How does a compresser water pump work?please explain in detail.?

Water pumps can  be reciprocal , geared or centrifugal.  A reciprocal pump works like an automobile cylinder.  water in the cylinder is forced out when the piston rises.  A valve closes to hold the water there.  On the downstroke, a valve opens to admit more water to the cylinder.  On the upstroke that valve closes, and the discharge valve opens.\n\nIn a geared pump, two meshing gears rotate in a very tight enclosure.  Water is admitted on one side.  The spaces between teeth carry water around the case to the discharge side.\n\nCentrifugal pumps spin water with a paddlewheel-like arrangement.  This gives the water energy in the form of velocity.  When this water is forced into a pipe, the energy converts from velocity to pressure.

The fountains are fed from a reservoir or aqueduct that is located much higher in the landscape. Gravity produces the pressure.\n\nYour household plumbing works on exactly the same principle. Your house doesn't have any motor or pump yet the water still fountains upwards when you turn on the hose. That's because the water towers and reservoirs are high enough above your tap to produce a significant pressure

If it is a high-volume, low pressure pump, one of the easiest ways is to get a long piece of clear tubing and make a U-tube manometer.  the pressure will cause the water to climb in the tube vented to the atmosphere, while the other end is connected to the pump outlet.  You measure the height of the water column, and can get the head directly in feet of water, a popular unit of measurement in the pump industry.  If it is a high pressure pump, a simple pressure gage from the local plumbing supply or hardware store will read in PSI.  In rough terms, 14.7 psi is approximately equal to 32.2 Feet of water column pressure.

I believe from my old chem eng days before I gave that up to become a model that a positive displacement pump is where the liquid is forced though the device by changing the volume of the pump e.g. a piston. Their operating characteristics are therefore relatively independant of pressure but they are less efficient with high volumes \n\nOther types of pumps e.g. centrifugal do not change the volume of pump or force liquid in the same way but rather alter the pressure by 'flinging' the liquid.

I don't think it is a good idea due to the compresser.  You could ask someone like at a Lowe's or Home depot store but, I really don't think you are supposed to.

The cooling system,works like a cars ,except there is no radiator. The water is pulled from the lake or ocean into the water pump,flows through all the water ports in the block and head,then go out . it is kind of a cycle ,in and out.

Do exactly the following:\n\n1 FULLY unwind the little knurled nut on your valve.\n2 Importantly - tap the unwound nut to break the seal in the valve. Ensure you hear a little blast of escaping air as you tap it - if not do it again.\n3 Now fit the adaptor and screw it on fully.\n4 Now apply your pump and everything should work fine.\n\nIf this doesn't work then either your valve or your pump is knackered. \n\nTesting the pump is easy - just put your finger over the nozzle and pump - a good farting sound is an excellent indicator its working just fine.\n\nTesting the valve is even easier - try the other tyre!

I assume you are talking about a central chiller plant setup. This is common on large campuses. There are a few high capacity centrifical or recepricating compressor water chillers that chill water and it is stored in large tanks to expand system capacity or ofset high peak deman energy costs. The chilled water is sent to buildings and used to cool them in a device not unlike a car radatior.

Here's how it works:\n\nThe air and water serve two different functions - the air is what is compressed, and pushes the water out of the back end of the rocket.  The water, although basically incompressible, is what makes the rocket go.  Momentum is always conserved, so whatever momentum (mass times speed) the water gets going out the back is also imparted to the rocket in the opposite direction.  You can think of it as positive and negative added momentum, creating a net change of zero.  The rocket is usually a much lower mass than the water, so the speed it achieves in order to match the momentum is higher than that of the water.\n\nAfter the water and air are expelled from the rocket, gravity is the only remaining force; the rocket slows, reverses direction, and lands on the ground.

You need to fill in more information.  There are many kinds of pumps, two major classes being positive displacement and centrifugal.  Traditionally, something like a swimming pool centrifugal  pump could never be reversed so power would be produced by forcing fluid through it.  So in that case, the pump cannot be used as a turbine.\n\nIf you take a positive displacement pump, like a roots-type blower (supercharger), you CAN run that in reverse and blow air in one end and get shaft power out.  \n\nHydraulic motors used to turn wheels slowly on construction equipment can also be used as pumps--they will work either way.  If you apply shaft power, you will get fluid power out.  If you apply fluid power, you will get shaft power out.  \n\nTurbine pumps are usually very specifically designed to run only in one direction and have shaft power going into them rather than out.

Gotta approach this using basic principles.\n\nEnergy is the integral of force applied over a distance.\nTheres two sets of forces working:\nfluid and gravitational.\n\nSo you make your control volume, and look at it.\nYou want to raise the water in it, thats mgh or rho*v*g*h\n\nYou also have to exert a pressure to push against the water ahead of it.  The downward pressure acting on your control volume is f/a so the force you must overcome is p*a and you are traversing distance h so the energy is p*a*h\n\nTherefore to raise the fluid vertically against a down pressure and against gravity the minimum energy (real world is lossy) is \nE = h*(mg+pa)

In simple terms, a displacement compressor squeezes the gas to increase it pressure. A dynamic compressor imparts extra velocity to the gas and then slows the gas down to convert this extra velocity to pressure. \n\nI as sure that the first three compressors mentioned in your question are displacement types. I believe the liquid ring is also but I am not completely sure.

They send it to cooling towers to turn the steam back into water, so they can take advantage, once again, of the mechanical energy involved in water expanding into steam.  Water expands a lot turning into steam, but when steam just turns into even hotter steam, the pressure increases, but not that much.\n\nSure they could be even more efficient by finding a good use for the extra heat, but that would be a bunch more machinery.

Basic Mechanics 101:\nThe Carburator mixes gas and air. The valve puts the mixture in the cylinder. The pistons compresses the mixture to a flash point. The spark plug provides a spark. The mixture burns up, pushing the cylinder, that turns the crank shaft, which turns the main shaft that is connected to a transmission or to what ever it is you want to turn.

Depends on your application.\n\nPump water from a shallow (less than 20ft)or deep (greater than 20ft) well?\nHow much volume(gpm) and pressure(psi) are you looking for?\nBased on standard house current at 110VAC or off of a car battery(12V) and how long do you plan to have this pump running (few minutes at a time or hr's or day's on end)?\n\nYour question can be simple or a major under taking. \n\nA simple pump, using an old washmachine pump and motor you can come up with a basic pump. This will work on a shallow application, meaning the pump can't draw water from a resavoir being very deep, maybe a few feet. \nA sump pump is also a very shallow well type, works from a jet principle, but can't deliver a lot of pressure 10-15psi for a short period of time.\n\nWater wells which are deep, > 30ft, usually have the pump submerged into the water which then pushes the water out vs drawing the water up.\nSome of the older pumps were of a piston design, inefficient compared todays jet pump standards.\n\nOtherwise an electric moter and a mechanical pump.
