how does compressor works?

Answer 1

#There is a diference between compressor and a pump.Pl. read below:
[Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible, so the main action of a pump is to transport liquids.]
#A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compression of a gas naturally increases its temperature.
-Since compression generates heat, the compressed gas is to be cooled between stages making the compression less adiabatic and more isothermal. The inter-stage coolers cause condensation meaning water separators with drain valves are present. The compressor flywheel may drive a cooling fan.

For instance in a typical diving compressor, the air is compressed in three stages. If each stage has a compression ratio of 7 to 1, the compressor can output 343 times atmospheric pressure (7 x 7 x 7 = 343 Atmospheres).
#I am giving working of a reciprocating compressor as there are many types of compressors. for detail please visit:
http://en.wikipedia.org/wiki/Gas_compressor

#A reciprocating compressor consists of a crankshaft (driven by either a gas engine, electric motor, or turbine) attached to a connecting rod, which transfers the rotary motion of the crankshaft to a crosshead. The crosshead travels back in forth in a crosshead guide. The crosshead converts the rotating motion to a reciprocating motion. The piton rod is attached to the crosshead and the piston (which is contained in a cylinder) is attached to the piston rod. The piston acting within the cylinder then compresses the gas contained within that cylinder. Gas enters the cylinder through a suction valve at suction pressure and is compressed to reach desired discharge pressure. When the gas reaches desired pressure, it is then discharged through a discharge valve. Desired discharge pressure can be reached through utilization of either a single or double acting cylinder. In a double acting cylinder, compression takes place at both the head end and crank end of the cylinder. The cylinder can be designed to accommodate any pressure or capacity, thus making the reciprocating compressor the most popular in the gas industry.

#Reciprocating compressors use pistons driven by a crankshaft. They can be either stationary or portable, can be single or multi-staged, and can be driven by electric motors or internal combustion engines. Small reciprocating compressors from 5 to 30 horsepower (hp) are commonly seen in automotive applications and are typically for intermittent duty. Larger reciprocating compressors up to 1000 hp are still commonly found in large industrial applications, but their numbers are declining as they are replaced by various other types of compressors. Discharge pressures can range from low pressure to very high pressure (>5000 psi or 35 MPa). In certain applications, such as air compression, multi-stage double-acting compressors are said to be the most efficient compressors available, and are typically larger, noisier, and more costly than comparable rotary units.

Answer 2

Simply put........A compressor is similar to an an auto engine without spark plugs or a fuel injection system, in that it sucks air or some other gas into a compression chamber via an intake valve on the downward piston suction stroke, and compresses the air or gas on the upward stroke of the piston. The compressed air is then released into a holding tank or into a compressed air hose.

The crankshaft of the compressor which powers the pistons up and down, and opens and closes the valves, is driven by a motor, either electrical or mechanical.

Answer 3

This explanation will have to be very basic as the full explanation will take many pages of text and diagrams. (Diagrams can't be used in this program).
(Also, PUMPS CANNOT be and are NOT COMPRESSORS, they add pressure energy to incompressible liquids but a liquid MUST NEVER be put through a compressor).

In many industries, compressors are used to add energy to gases in the form of pressure for various uses and processes. Compressors of many, varied types are utilised for this purpose.
In some cases, high pressure is needed in order to liquefy a gas. This is often carried out to greatly decrease the volume of the gas to allow storage and transportation of the liquids to anywhere in the world.
There are 3 main types of compressor…
1…Centrifugal
2…Axial Flow
3…Reciprocating (Piston) Types

Answer 4

Essentially a compressor is a pump, that draws, compresses, then discharges fluid. Air, and refrigerating pumps are designed to discharge vapor only, and will fail, when forced to pump liquid. When these type compressors fill with liquid, valve damage will occur, and perhaps lock up.

Answer 5

When someone does not know how a compressor works, which now adays is a common everyday thing, all you bragging self important people take the opportunity to tell us how great you are that you know every technical aspect. You fail to answer the question in terms that such a person can comprehend.

Answer 6

By means of electrical or mechanical power the TO&FRO or turbulance moments of the piston inside cylinder suucks the air incase of air compressors and refrigerent in case of a/c & refrigeration system through inlet valve /port and compress into tank incase of air compressor and to the system incase of a/ & refrigeration.

Answer 7

a compressor pulls in a gas or liquid in then condenses it by putting it in a smaller space than it would normally occupy. Once it pulls in more than is normally occupying a certain space then the container is pressurized depending on the pressure wanted is what determines how much gas or liquid will be confinded in the space at any given time. When the gas or liquid is pressurized the matter wants to expand and when it is released from the compressor, the gas or liquid expanding to its normal pressure causes it to cool rapidly.

pump and check valves...
