Multi Stage Air Compressor Working Principle

Air will enter to the compressor at the impeller eye axially and compressed air will leave the compressor in radial direction.

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. The initial volume when the piston is at top is zero assuming there is no bumping clearance. 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. Ultimately your choice between a one stage or multi stage compressor should be based on the size and nature of your operations. In three stage air compressor fresh air from the atmosphere enters in a first stage low pressure cylinder. Air enters through a suction filter.

There you have to use a multi stage air compressor. We normally use three stage reciprocating air compressors as a. Working principle of multi stage reciprocating compressor mp4. High discharge air pressure is achieved by a multi stage air compressor.

Learn more about single and two stage air compressors. 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. The working principle of multistage air compressor is same as double stage air compressor.

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

Thus as the piston moves from top to bottom a volume of air v1 is drawn into the 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. 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.
