Sixth Day on October 4
as Luxor is my first day of the wounded day, the event from the first two pairs of eyes seems to be more meaningful to express, so on October 3 in the travel by the caregiver to do it. from today’s start again for me to record.
Today is the day after arrival in Luxor, project sites to the east coast of the Nile Karnak (Karnak) Temple and Luxor Temple (LuxorAmonTemple ).
8:30 am, everyone check out the collection, ending the cruise 4 days 3 nights on the trip. and then, straight from Karnak. Luxor as the ancient capital of Egypt, where countless monuments. the Karnak Temple and the Nile is the West Bank, Valley of the Kings can and said Yu Liang’s name attractions. here was famous because it is not only a temple but a temple group. by the continuous construction of 18 pharaohs of Egypt, an Egyptian dynasty every architectural features and culture is reflected in this, the Egyptians are proud to be known as the Egyptian natural museum. there should be the most famous film Death on the Nile The famous scene in the show off from the main building Ramses 2 of the World 23-meter by 134 5 m thick composed of a central hall, a large stone and the construction of the obelisk of Queen 哈特普苏特.
entered Qana g temples, eyes on me and caregiver is not enough to make the up. We visited Trinity Temple sequential structure of the Temple of Ramses a group of the world, the central hall, the world’s most ancient man-made lake and so on (it is that can not remember which of these are from the construction of the Pharaoh) and then around the artificial lake on the Egyptian beetle turning stone 7 times, are supposed to bring luck. Ha ha. Although just injured ankle yesterday, and I basically not be affected, to walk the momentum seemingly to be higher than any other person. Therefore, the Karnak Temple which most of the places are run again. By contrast, found a problem, that is, ancient Egyptian architecture standards and the passage of years has nothing to do. is not to say the more the better new or the older the better. but strong and a pharaoh or relevant. a powerful Pharaoh, the construction of the temple, from the construction process or mural sculpture standards for far more than the weak Pharaoh. Let me most interested is 哈普特苏特 Queen obelisk engraved with the letter and the central hall of the ubiquitous murals. If the obelisk itself shaping and grinding can also be understood, then the obelisk on how deep the hieroglyphics carved up, then is an eternal mystery. It does not look like Chinese writing stone, as you can see traces of hewn. text at the bottom of wide, flat line, people feel these words is not carved in stone and should be in the soft mud. Perhaps there have been many times in the Chinese martial arts novels of the \Hall is also the same problem. all places where you can write all the text or the mural on the cloud-riding god, people who strongly feel that the construction at the time, how would like more information passed on to future generations. but trying to convey in the end what is it? this rich text and information has not yet been completely deciphered, but after all, and left behind a clue to find the answer, which is why there is a natural museum of the biggest reasons for it.
After visiting card ng temple, our next stop is the Temple of Luxor. two very close distance. in the completion of the original, Karnak and Luxor temple was originally connected. Karnak Temple As a priest, the Luxor temple which is the Pharaoh’s palace. between two places, there is an approximately 1000 meters of road, the road sides of the Sphinx guarded by hundreds of groups. Of course, now the temple of two which have become residential areas, and the ancient Sphinx Avenue, retains only the remains of the Temple of Luxor in front of a small section of it.
contrast, the Luxor Temple as card ng spectacular temple. But the gates of the obelisk and the Pharaoh as the embodiment of ancient Egypt is still strong. After all, the Luxor Temple Ramses 2, the world is experiencing the product, as a great emperor, should be results will not be allowed to own any shortcomings. Luxor Temple has two symmetrical front had a large obelisk, but only one, and seemed more abrupt. Our guide, Ali brothers, brought the matter to could not help but anger from the heart to the bile from the evil side of health, and we all say, \French occupation of Egypt, and here, as their colony. King of France, a France-made watches as a gift at the time of the Egyptian king Muhammad Ali, Ali, of the same name — senior tour ah but if now The words of Ali when the king is estimated that the king of France also gave it a piece of granite. Unfortunately, Ali was king of some Shamao, grateful for the next Sato, people given us a total time on the East, we have to give it away as a ah. asked to ask men, let me state there is this thing? men said that the king not to mention you are really there on, we effect that one of the obelisk is the record not just time? Ali King a, uh, the good. knock down to foreigners! on such a, Luxor Temple obelisk in front of a pair of children separated the two so.
Note: Also this one, now stands in France Concorde.
Lu uxeau after visiting the temple, time is noon. guides us in the car asked, in the day is lunch is a meal in Egypt. It is not obvious you, who come to Egypt to eat Chinese food? certainly Egyptian food ah. We Brother Ali tour guide looked a little disappointed, it is estimated he wanted to eat the dishes? Ha ha. But Ali is still no complaints, takes us to the exterior looks a very good restaurant. had such a hot day, we all want in the room inside to eat, so you can cool a bit. However, entering the house, found that although it will take a group of Western tourists are eating may be the air that shares the taste of decoration. This can not stand, or outside the arbor it. did not think , as we sit in the arbor, shed the top of the fan in the fog began to spray it! such a blow on the fans, well, more comfortable than air-conditioned room! in or buffet lunch, the Egyptian tourism industry seems good provide this, butter chicken, tomato beef, pasta, fish steak … these are the things I like to eat, this can be Laozhao the. Ha ha. I see the edge of a beverage and ice cream stalls, in the past asked a moment, the scope of ice cream are buffet, casual eating. and spend money to buy drinks. It seems not all parts of Egypt to provide free drinks ah. and then find out a bit a of a 330ML of cola to two dollars. not crazy, right? not, eating ice cream! the same. caregiver taking advantage of photographic skill and North Sister, I went to Beijing and uncle eat and chat, the uncle visited many countries, Asia and Europe slipped a times, and then busy in Africa and South America has. Oh,the north face backpack, it seems we still have to keep ah!
dinner, and his party arrived here this evening we stayed in the hotel-maritim. Although we pray all the way from the city near the hotel that can be bus or The more open the more distant, until the suburbs before it stopped. But when we get off into the hotel, they immediately attract the environment here. fabled Luxor hotel really deserved reputation first. maritim hotel is located in the Eastern Nile a lake peninsula, facing the Nile West Bank, is the best place to view sunset. the whole atmosphere of the hotel were farmers, a complete circuit of the so-called building, is actually a circular cross section of construction, a total of 16 inter-level suites The distribution of the edge of the circle. appearance is very creative. room also extremely spacious and clean interior.
I and caregiver in the room and rest a while, then began another tour in the hotel to buy some postcards .6 o’clock , tour the city car to Luxor for dinner we have received. Oh, I must take this chance! finished, we did not want to get right back to the hotel guide, wander in Luxor after their taxi back. guides though not very happy, but still agreed.

The low pulsation rate and gentle performance of this Roots-type positive displacement pump is achieved due to a combination of its two 90° helical twisted rotors,nike air max 2000, and a triangular shaped sealing line configuration, both at the point of suction and at the point of discharge. This design produces a continuous and non-vorticuless flow with equal volume. High capacity industrial “air compressors” have been designed to employ this principle, as well as most “superchargers” used on internal combustion engines, and even a brand of civil defense siren, the Federal Signal Corporation’s Thunderbolt.

A Positive Displacement Pump must not be operated against a closed valve on the discharge side of the pump because it has no shut-off head like Centrifugal Pumps. A Positive Displacement Pump operating against a closed discharge valve, will continue to produce flow until the pressure in the discharge line are increased until the line bursts or the pump is severely damaged – or both.

Because of the wide variety of applications, pumps have a plethora of shapes and sizes: from very large to very small, from handling gas to handling liquid, from high pressure to low pressure, and from high volume to low volume.

Positive displacement rotary pumps are pumps that move fluid using the principles of rotation. The vacuum created by the rotation of the pump captures and draws in the liquid. Rotary pumps are very efficient because they naturally remove air from the lines, eliminating the need to bleed the air from the lines manually. Positive displacement rotary pumps also have their weaknesses. Because of the nature of the pump, the clearance between the rotating pump and the outer edge must be very close, requiring that the pumps rotate at a slow, steady speed. If rotary pumps are operated at high speeds, the fluids will cause erosion, much as ocean waves polish stones or erode rock into sand. Rotary pumps that experience such erosion eventually show signs of enlarged clearances, which allow liquid to slip through and detract from the efficiency of the pump. Positive displacement rotary pumps can be grouped into three main types. Gear pumps are the simplest type of rotary pumps, consisting of two gears laid out side-by-side with their teeth enmeshed. The gears turn away from each other, creating a current that traps fluid between the teeth on the gears and the outer casing, eventually releasing the fluid on the discharge side of the pump as the teeth mesh and go around again. Many small teeth maintain a constant flow of fluid, while fewer, larger teeth create a tendency for the pump to discharge fluids in short, pulsing gushes. Screw pumps are a more complicated type of rotary pumps, featuring two screws with opposing thread ―- that is, one screw turns clockwise, and the other counterclockwise. The screws are each mounted on shafts that run parallel to each other; the shafts also have gears on them that mesh with each other in order to turn the shafts together and keep everything in place. The turning of the screws, and consequently the shafts to which they are mounted, draws the fluid through the pump. As with other forms of rotary pumps, the clearance between moving parts and the pump’s casing is minimal. Moving vane pumps are the third type of rotary pumps, consisting of a cylindrical rotor encased in a similarly shaped housing. As the rotor turns, the vanes trap fluid between the rotor and the casing, drawing the fluid through the pump.

Pump efficiency is defined as the ratio of the power imparted on the fluid by the pump in relation to the power supplied to drive the pump. Its value is not fixed for a given pump, efficiency is a function of the discharge and therefore also operating head. For centrifugal pumps, the efficiency tends to increase with flow rate up to a point midway through the operating range (peak efficiency) and then declines as flow rates rise further. Pump performance data such as this is usually supplied by the manufacturer before pump selection. Pump efficiencies tend to decline over time due to wear (e.g. increasing clearances as impellers reduce in size).

Today, hand operated village pumps are considered the most sustainable low cost option for safe water supply in resource poor settings, often in rural areas in developing countries. A hand pump opens access to deeper groundwater that is often not polluted and also improves the safety of a well by protecting the water source from contaminated buckets. Pumps like the Afridev pump are designed to be cheap to build and install, and easy to maintain with simple parts. However, scarcity of spare parts for these type of pumps in some regions of Africa has diminished their utility for these areas.[citation needed]

Not all plants are refineries, however, and different results can be expected elsewhere. In chemical plants, pumps have traditionally been “throw-away” items as chemical attack can result in limited life. Things have improved in recent years, but the somewhat restricted space available in “old” DIN and ASME-standardized stuffing boxes places limits on the type of seal that can be fitted. Unless the pump user upgrades the seal chamber, only the more compact and simple versions can be accommodated. Without this upgrading, lifetimes in chemical installations are generally believed to be around 50 to 60 percent of the refinery values.

Reciprocating Pumps

A device or machine that compresses and/or transports fluids, usually by pressure or suction, or both; may be used to remove water from a construction site or to convey water from one elevation to another.

Plimsolls; a type of sports shoe with a rubber sole used in games such as tennis and badminton.

Multiphase pumping applications, also referred to as tri-phase, have grown due to increased oil drilling activity. In addition, the economics of multiphase production is attractive to upstream operations as it leads to simpler, smaller in-field installations, reduced equipment costs and improved production rates. In essence, the multiphase pump can accommodate all fluid stream properties with one piece of equipment, which has a smaller footprint. Often, two smaller multiphase pumps are installed in series rather than having just one massive pump.

A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure and flow rate of a fluid. Centrifugal pumps are the most common type of pump used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward or axially into a diffuser or volute chamber, from where it exits into the downstream piping system. Centrifugal pumps are typically used for large discharge through smaller heads.

Often simply referred to as centrifugal pumps. The fluid enters along the axial plane, is accelerated by the impeller and exits at right angles to the shaft (radially). Radial flow pumps operate at higher pressures and lower flow rates than axial and mixed flow pumps.

Reciprocating pumps are those which cause the fluid to move using one or more oscillating pistons, plungers or membranes (diaphragms).

Velocity pumps A centrifugal pump uses a spinning “impeller” which has backward-swept arms

Pump efficiency is an important aspect and pumps should be regularly tested. Thermodynamic pump testing is one method.

The screw centrifugal pump is a popular choice for handling delicate products such as food and crystals. Its low shear characteristic reduces emulsification when pumping mixtures making it ideal for pumping oily water and Return Activated Sludge [RAS] as it does not damage the floc. The pump’s ability to pass long fibrous materials such as rope without clogging makes it a frequent choice for municipal waste water applications. A screw centrifugal pump typically has an operating efficiency of 70% to 85%. It has a relatively steeply rising head/capacity curve shape giving it good flow control capability over its allowable operating range

A plunger pump consists of a cylinder with a reciprocating plunger in it. The suction and discharge valves are mounted in the head of the cylinder. In the suction stroke the plunger retracts and the suction valves open causing suction of fluid into the cylinder. In the forward stroke the plunger pushes the liquid out of the discharge valve.

It functions as a hydraulic transformer that takes in water at one “hydraulic head” (pressure) and flow-rate, and outputs water at a higher hydraulic-head and lower flow-rate. The device utilizes the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started.

With only one cylinder the fluid flow varies between maximum flow when the plunger moves through the middle positions, and zero flow when the plunger is at the end positions. A lot of energy is wasted when the fluid is accelerated in the piping system. Vibration and “water hammer” may be a serious problem. In general the problems are compensated for by using two or more cylinders not working in phase with each other.

The positive displacement principle applies whether the pump is a

where ΔP is the change in total pressure between the inlet and outlet (in Pa), and the fluid flowrate is given in m^3/s. The total pressure may have gravitational, static pressure and kinetic energy components; i.e. energy is distributed between change in the fluid’s gravitational potential energy (going up or down hill), change in velocity, or change in static pressure. η is the pump efficiency, and may be given by the manufacturer’s information, such as in the form of a pump curve, and is typically derived from either fluid dynamics simulation (i.e. solutions to the Navier-stokes for the particular pump geometry), or by testing. The efficiency of the pump will depend upon the pump’s configuration and operating conditions (such as rotational speed, fluid density and viscosity etc).

A pump is a device used to move fluids, such as liquids or slurries, or gases.

Mixed flow pumps

As the name indicates, multiphase pumps and their mechanical seals can encounter a large variation in service conditions such as changing process fluid composition, temperature variations, high and low operating pressures and exposure to abrasive/erosive media. The challenge is selecting the appropriate mechanical seal arrangement and support system to ensure maximized seal life and its overall effectiveness.[7][8][9]

A positive displacement pump causes a fluid to move by trapping a fixed amount of it then forcing (displacing) that trapped volume into the discharge pipe. A positive displacement pump can be further classified according to the mechanism used to move the fluid:

Mixed flow pumps, as the name suggests, function as a compromise between radial and axial flow pumps, the fluid experiences both radial acceleration and lift and exits the impeller somewhere between 0-90 degrees from the axial direction. As a consequence mixed flow pumps operate at higher pressures than axial flow pumps while delivering higher discharges than radial flow pumps. The exit angle of the flow dictates the pressure head-discharge characteristic in relation to radial and mixed flow.

One modern application of positive displacement diaphragm pumps is compressed-air-powered double-diaphragm pumps. Run on compressed air these pumps are intrinsically safe by design, although all manufacturers offer ATEX certified models to comply with industry regulation. Commonly seen in all areas of industry from shipping to processing, SandPiper, Wilden Pumps or ARO are generally the larger of the brands. They are relatively inexpensive and can be used for almost any duty from pumping water out of bunds, to pumping hydrochloric acid from secure storage (dependent on how the pump is manufactured – elastomers / body construction). Lift is normally limited to roughly 6m although heads can reach almost 200 Psi.[citation needed]

It goes without saying that unscheduled maintenance often is one of the most significant costs of ownership, and failures of mechanical seals and bearings are among the major causes. Keep in mind the potential value of selecting pumps that cost more initially, but last much longer between repairs. The MTBF of a better pump may be one to four years longer than that of its non-upgraded counterpart. Consider that published average values of avoided pump failures range from $2600 to $12,000. This does not include lost opportunity costs. One pump fire occurs per 1000 failures. Having fewer pump failures means having fewer destructive pump fires.

From this came the expression “parish pump” for “the sort of matter chattered about by people when they meet when they go to get water”, “matter of only local interest”. However water from pitcher pumps are more prone to contamination since it is drawn directly from the soil and does not undergo filtration, this might cause gastrointestinal related diseases.

This uses two meshed gears rotating in a closely fitted casing. Fluid is pumped around the outer periphery by being trapped in the tooth spaces. It does not travel back on the meshed part, since the teeth mesh closely in the centre. Widely used on car engine oil pumps.

Pump efficiency

Progressive Cavity Pumps (Positive Displacement) Progressive cavity pumps are single-screw types typically used in shallow wells or at the surface. This pump is mainly used on surface applications where the pumped fluid may contain a considerable amount of solids such as sand and dirt.

Buffer Tank A buffer tank is often installed upstream of the pump suction nozzle in case of a slug flow. The buffer tank breaks the energy of the liquid slug, smoothes any fluctuations in the incoming flow and acts as a sand trap.

Positive Displacement Pumps has an expanding cavity on the suction side and a decreasing cavity on the discharge side. Liquid flows into the pumps as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses. The volume is constant given each cycle of operation.

A relief or safety valve on the discharge side of the Positive Displacement Pump is therefore absolutely necessary. The relief valve can be internal or external. The pump manufacturer normally has the option to supply internal relief or safety valves. The internal valve should in general only be used as a safety precaution, an external relief valve installed in the discharge line with a return line back to the suction line or supply tank is recommended.

Gravity pumps include the syphon and Heron’s fountain – and there also important qanat or foggara systems which simply use downhill flow to take water from far-underground aquifers in high areas to consumers at lower elevations. The hydraulic ram is also sometimes referred to as a gravity pump.

A pump displaces a volume by physical or mechanical action. Pumps fall into five major groups: direct lift, displacement, velocity, buoyancy and gravity pumps.[1] Their names describe the method for moving a fluid.

This uses a jet, often of steam, to create a low pressure. This low pressure sucks in fluid and propels it into a higher pressure region.

For a typical “pumping” configuration, the work is imparted on the fluid, and is thus positive. For the fluid imparting the work on the pump (i.e. a turbine), the work is negative.e power required to drive the pump is determined by dividing the output power by the pump efficiency. Furthermore, this definition encompasses pumps with no moving parts, such as a siphon.

In early 2005, Gordon Buck, John Crane Inc.’s chief engineer for Field Operations in Baton Rouge, LA, examined the repair records for a number of refinery and chemical plants to obtain meaningful reliability data for centrifugal pumps. A total of 15 operating plants having nearly 15,000 pumps were included in the survey. The smallest of these plants had about 100 pumps; several plants had over 2000. All facilities were located in the United States. In addition, all plants had some type of pump reliability program in progress. Some of these programs could be considered as “new,” others as “renewed” and still others as “established.” Many of these plants―but not all―had an alliance arrangement with John Crane. In some cases, the alliance contract included having a John Crane Inc. technician or engineer on-site to coordinate various aspects of the program.

One important part of system design involves matching the pipeline headloss-flow characteristic with the appropriate pump or pumps which will operate at or close to the point of maximum efficiency. There are free tools that help calculate head needed and show pump curves including their Best Efficiency Points (BEP).[10]

A machine that draws a fluid into itself through an entrance port and forces the fluid out through an exhaust port (see illustration). A pump may serve to move liquid, as in a cross-country pipeline; to lift liquid, as from a well or to the top of a tall building; or to put fluid under pressure, as in a hydraulic brake. These applications depend predominantly upon the discharge characteristic of the pump. A pump may also serve to empty a container, as in a vacuum pump or a sump pump, in which case the application depends primarily on its intake characteristic. See also Centrifugal pump; Compressor; Displacement pump; Fan; Fuel pump; Pumping machinery; Vacuum pump.

As has been noted, a typical pump failure based on actual year 2002 reports, costs $5,000 on average. This includes costs for material, parts, labor and overhead. Let us now assume that the MTBF for a particular pump is 12 months and that it could be extended to 18 months. This would result in a cost avoidance of $2,500/yr―which is greater than the premium one would pay for the reliability-upgraded centrifugal pump.[3][4][5]

Examining pump repair records and MTBF (mean time between failures) is of great importance to responsible and conscientious pump users. In view of that fact, the preface to the 2006 Pump User’s Handbook alludes to “pump failure” statistics. For the sake of convenience, these failure statistics often are translated into MTBF (in this case, installed life before failure).[3]

Pumps are used throughout society for a variety of purposes. Early applications includes the use of the windmill or watermill to pump water. Today, the pump is used for irrigation, water supply, gasoline supply, air conditioning systems, refrigeration (usually called a compressor), chemical movement, sewage movement, flood control, marine services, etc.

Twin Screw (Positive Displacement) The twin screw pump is constructed of two intermeshing screws that force the movement of the pumped fluid. Twin screw pumps are often used when pumping conditions contain high gas volume fractions and fluctuating inlet conditions. Four mechanical seals are required to seal the two shafts.

The screw centrifugal impeller was invented in 1960 by the late Martin St?hle, the founder of Hidrostal AG. He had received an order from the Amial S.A. fish processing factory in Chimbote (Peru) for the development of a system for transporting fish from the nets into a boat, and from the boat into the fish processing plant. The pump was to work reliably without damaging the fish. The result was the pump with the characteristic screw centrifugal impeller. This invention was a great success. It has since been used in many ways throughout the world in countless other fluid handling systems.

Helico-Axial Pumps (Centrifugal) A rotodynamic pump with one single shaft requiring two mechanical seals. This pump utilizes an open-type axial impeller. This pump type is often referred to as a “Poseidon Pump” and can be described as a cross between an axial compressor and a centrifugal pump.

On this page

Centrifugal pumps are most often associated with the radial flow type. However, the term “centrifugal pump” can be used to describe all impeller type rotodynamic pumps[2] including the radial, axial and mixed flow variations.

Radial flow pumps

plunger pumps
diaphragm pumps

Electric Submersible Pumps (Centrifugal) These pumps are basically multistage centrifugal pumps and are widely used in oil well applications as a method for artificial lift. These pumps are usually specified when the pumped fluid is mainly liquid.

Rotodynamic pumps (or dynamic pumps) are a type of velocity pump in which kinetic energy is added to the fluid by increasing the flow velocity. This increase in energy is converted to a gain in potential energy (pressure) when the velocity is reduced prior to or as the flow exits the pump into the discharge pipe. This conversion of kinetic energy to pressure can be explained by the First law of thermodynamics or more specifically by Bernoulli’s principle. Dynamic pumps can be further subdivided according to the means in which the velocity gain is achieved.

Pump Repairs

Axial flow pumps differ from radial flow in that the fluid enters and exits along the same direction parallel to the rotating shaft. The fluid is not accelerated but instead “lifted” by the action of the impeller. They may be likened to a propeller spinning in a length of tube. Axial flow pumps operate at much lower pressures and higher flow rates than radial flow pumps.

Priming a pump

reciprocating
rotary

In diaphragm pumps, the plunger pressurizes hydraulic oil which is used to flex a diaphragm in the pumping cylinder. Diaphragm valves are used to pump hazardous and toxic fluids.

From an initial design point of view, engineers often use a quantity termed the specific speed to identify the most suitable pump type for a particular combination of flow rate and head.

Machine that uses energy to raise, transport, or compress fluids. Pumps are classified by how they transfer energy to the fluid. The basic methods are volume displacement, addition of kinetic energy, and use of electromagnetic force. Pumps in which displacement is accomplished mechanically are called positive displacement pumps. Kinetic pumps pass kinetic energy to the fluid by means of a rapidly rotating impeller (blade). To use electromagnetic force, the fluid being pumped must be a good electrical conductor. Pumps used to transport or pressurize gases are called compressors, blowers, or fans.

The impeller has a single blade, axially extended at the inlet and developed around its axis much like a corkscrew. Linking this to a centrifugal outlet allows pumping with the minimum of agitation and shear, essential factors when product bruising, liquid emulsification or clogging is to be avoided.

Widely used for pumping difficult materials such as sewage sludge contaminated with large particles, this pump consists of a helical shaped rotor, about 10 times as long as its width. This can be visualized as a central core of diameter x, with typically a curved spiral wound around of thickness half x, although of course in reality it is made from one casting. This shaft fits inside a heavy duty rubber sleeve, of wall thickness typically x also. As the shaft rotates, fluid is gradually forced up the rubber sleeve. Such pumps can develop very high pressure at quite low volumes.

Positive Displacement Pumps, unlike Centrifugal or Roto-dynamic Pumps, will produce the same flow at a given speed (RPM) no matter the discharge pressure.

These types of pumps have a number of characteristics:

Reciprocating-type pumps require a system of suction and discharge valves to ensure that the fluid moves in a positive direction. Pumps in this category range from having “simplex” one cylinder, to in some cases “quad” four cylinders or more. Most reciprocating-type pumps are “duplex” (two) or “triplex” (three) cylinder. Furthermore, they can be either “single acting” independent suction and discharge strokes or “double acting” suction and discharge in both directions. The pumps can be powered by air, steam or through a belt drive from an engine or motor. This type of pump was used extensively in the early days of steam propulsion (19th century) as boiler feed water pumps. Though still used today, reciprocating pumps are typically used for pumping highly viscous fluids including concrete and heavy oils and special applications demanding low flow rates against high resistance.

Centrifugal pump
Main article: Centrifugal pump

For midstream and upstream operations, multiphase pumps can be located onshore or offshore and can be connected to single or multiple wellheads. Basically, multiphase pumps are used to transport the untreated flow stream produced from oil wells to downstream processes or gathering facilities. This means that the pump may handle a flow stream (well stream) from 100 percent gas to 100 percent liquid and every imaginable combination in between. The flow stream can also contain abrasives such as sand and dirt. Multiphase pumps are designed to operate under changing/fluctuating process conditions. Multiphase pumping also helps eliminate emissions of greenhouse gases as operators strive to minimize the flaring of gas and the venting of tanks where possible.[7]

  Columbia Encyclopedia: pump Top Home > Library > Miscellaneous > Columbia Encyclopedia pump, device to lift, transfer, or increase the pressure of a fluid (gas or liquid) or to create a vacuum in an enclosed space by the removal of a gas (see vacuum pumps under vacuum). The centrifugal pump, the most common kind, consists basically of a rotating device, called an impeller, inside a casing. The fluid to be pumped enters the casing near the shaft of the impeller. Vanes attached to the spinning impeller give the fluid a high velocity so that it can move through an outlet. The reciprocating pump moves a fluid by using a piston that travels back and forth in a cylinder with valves to help control the flow direction. Examples are the lift pump and the force pump. In a lift pump the piston and cylinder are positioned vertically. When the piston moves upward, atmospheric pressure pushes water into the cylinder to fill the empty space beneath the piston. On the downward stroke, the water in the cylinder is forced to flow above the piston. Reversing direction, the piston moves up, allowing more water to come up under it into the cylinder and lifting the water held above it to an outlet pipe where the water flows out of the pump. Since atmospheric pressure will support a column of water no higher than about 33 ft (10 m), a lift pump can raise water no farther than this distance. The rotary pump is like the reciprocating pump in that it allows a fluid to fill a space that then decreases in volume, forcing the fluid out of the space. However, unlike a reciprocating pump, it has no valves and uses one or more rotating components in place of a piston. The jet pump has no moving parts; it uses a swiftly moving fluid to induce motion in another fluid. For example an atomizer, a type of jet pump, uses a high-speed stream of air to pump a liquid, such as a perfume. Compressors are used to pump air or other gases into a closed container. They range from hand pumps to large power-driven devices that furnish compressed air for operating pneumatic machinery and for various other purposes. In nuclear reactors that use liquid radioactive metal, the nonmechanical electromagnetic pump is employed. An electric current is either induced in the liquid metal or is passed through it by electrodes. A magnetic field surrounding the pipe then propels the current-carrying liquid forward.

Axial flow pumps
Main article: Axial flow pump

One sort of pump once common worldwide was a hand-powered water pump over a water well where people could work it to extract water, before most houses had individual water supplies.

Liquid and slurry pumps can lose prime and this will require the pump to be primed by adding liquid to the pump and inlet pipes to get the pump started. Loss of “prime” is usually due to ingestion of air into the pump. The clearances and displacement ratios in pumps used for liquids and other more viscous fluids cannot displace the air due to its lower density.

Positive Displacement Pumps are “constant flow machines”

v.

One practical difference between dynamic and positive displacement pumps is their ability to operate under closed valve conditions. Positive displacement pumps physically displace the fluid; hence closing a valve downstream of a positive displacement pump will result in a continual build up in pressure resulting in mechanical failure of either pipeline or pump. Dynamic pumps differ in that they can be safely operated under closed valve conditions (for short periods of time).

A peristaltic pump is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible tube fitted inside a circular pump casing (though linear peristaltic pumps have been made). A rotor with a number of “rollers”, “shoes” or “wipers” attached to the external circumference compresses the flexible tube. As the rotor turns, the part of the tube under compression closes (or “occludes”) thus forcing the fluid to be pumped to move through the tube. Additionally, as the tube opens to its natural state after the passing of the cam (”restitution”) fluid flow is induced to the pump. This process is called peristalsis and is used in many biological systems such as the gastrointestinal tract.

A hydraulic ram is a water pump powered by hydropower.

The power imparted into a fluid will increase the energy of the fluid per unit volume. Thus the power relationship is between the conversion of the mechanical energy of the pump mechanism and the fluid elements within the pump. In general, this is governed by a series of simultaneous differential equations, known as the Navier-Stokes equations. However a more simple equation relating only the different energies in the fluid, known as Bernoulli’s equation can be used. Hence the work, W, done by or on a pump is given by:
