Multi Stage Air Compressor Working Principle

In three stage air compressor fresh air from the atmosphere enters in a first stage low pressure cylinder.

Multi stage air compressor working principle.

The atmospheric pressure is p1. This cooled air is passed to the intermediate stage where it is again getting compressed and heated. 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. 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. After the first compression stage air passes through a heat exchanger where it is cooled before arriving at the second cylinder. Losses in a centrifugal compressor. We normally use three stage reciprocating air compressors as a.

Thus as the piston moves from top to bottom a volume of air v1 is drawn into the compressor. The air compressor draws in air from the atmosphere. High discharge air pressure is achieved by a multi stage air compressor. These blades can be forward leaning radial or backward leaning depending upon the desired output.

Cooling the air reduces the work needed to compress it during the second or third stages. Air will enter to the compressor at the impeller eye axially and compressed air will leave the compressor in radial direction. The rotor provide velocity to the gas with blades that are attached to a rotating disc. Learn more about single and two stage air compressors.

How multi stage compressors work multi stage compressors feature two or more piston cylinders each of a different diameter. 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. The impellers are assembled or mounted on a steel shaft and this assembly is known as compressor rotor mostly in multi stage compressors. A multi stage compressor is one in which there are several cylinders of different diameters.

Ultimately your choice between a one stage or multi stage compressor should be based on the size and nature of your operations. Working principle of multi stage reciprocating compressor mp4. The initial volume when the piston is at top is zero assuming there is no bumping clearance.
