Multi Stage Air Compressor Working Principle

Air enters through a suction filter.

Multi stage air compressor working principle.

This cooled air is passed to the intermediate stage where it is again getting compressed and heated. The initial volume when the piston is at top is zero assuming there is no bumping clearance. 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. The atmospheric pressure is p1. The working principle of multistage air compressor is same as double stage air compressor.

The air compressor draws in air from the atmosphere. The rotor provide velocity to the gas with blades that are attached to a rotating disc. The impellers are assembled or mounted on a steel shaft and this assembly is known as compressor rotor mostly in multi stage compressors. These blades can be forward leaning radial or backward leaning depending upon the desired output.

Losses in a centrifugal compressor. How multi stage compressors work multi stage compressors feature two or more piston cylinders each of a different diameter. High discharge air pressure is achieved by a multi stage air compressor. We normally use three stage reciprocating air compressors as a.

Learn more about single and two stage air compressors. Air will enter to the compressor at the impeller eye axially and compressed air will leave the compressor in radial direction. Working principle of multi stage reciprocating compressor mp4. 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.

A multi stage compressor is one in which there are several cylinders of different diameters. 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. After the first compression stage air passes through a heat exchanger where it is cooled before arriving at the second cylinder.
