Multi Stage Air Compressor Working Principle

The atmospheric pressure is p1.

Multi stage air compressor working principle. These blades can be forward leaning radial or backward leaning depending upon the desired output. We normally use three stage reciprocating air compressors as a. After the first compression stage air passes through a heat exchanger where it is cooled before arriving at the second cylinder. Air enters through a suction filter.

The intake of air in the first stage gets compressed and then it is passed over a cooler to achieve a temperature very close to ambient air. Working principle of multi stage reciprocating compressor mp4. Cooling the air reduces the work needed to compress it during the second or third stages. The rotor provide velocity to the gas with blades that are attached to a rotating disc.

High discharge air pressure is achieved by a multi stage air compressor. Multi stage air compressor units with various cylinder configurations and piston shapes figure 1 above are used in conjunction with intermediate and after cooling to provide the nearest possible approach to the ideal of isothermal compression. Learn more about single and two stage air compressors. The impellers are assembled or mounted on a steel shaft and this assembly is known as compressor rotor mostly in multi stage compressors.

This cooled air is passed to the intermediate stage where it is again getting compressed and heated. The working principle of multistage air compressor is same as double stage air compressor. Losses in a centrifugal compressor. The air compressor draws in air from the atmosphere.

A multi stage compressor is one in which there are several cylinders of different diameters. A pressure ratio of 4 1 could be achieved with single stage centrifugal compressor and higher pressure ratio of 12 1 is also possible to achieve with multi stage centrifugal compressor. Ultimately your choice between a one stage or multi stage compressor should be based on the size and nature of your operations. There you have to use a multi stage air compressor.

In summary one stage units are for small scale projects and personal use while two stage models are more geared toward industrial scale arsenals. In three stage air compressor fresh air from the atmosphere enters in a first stage low pressure cylinder. Thus as the piston moves from top to bottom a volume of air v1 is drawn into the compressor.
