Multi Stage Air Compressor Diagram

Thus we have seen the actual operation of an air compressor and its theoretical p v diagram.

Multi stage air compressor diagram.

A compressor operating at lower output consumes less electricity. For pressures exceeding 30 bar multi stage compressors are required. For maximum compressor efficiency it is desirable to cool air after one stage using inter stage cooler. While straightforward this setup is limited in its efficiency and capacity for delivering high volumes of pressurized air.

In two stage compressor initial compression takes place in the low pressure cylinder. In a two stage compressor the air is compressed twice for double the pressure. Refer to the diagram of a multi stage compressor where it is evident that the work done by the compressor is less when compared to a single stage machine for same delivery pressure. In a single stage compressor the air is compressed one time.

In single stage compressor entire compression of air takes place in single stroke of the piston. The compressed air at the pressure p2 volume v2 and temperature t2 is delivered out of the compressor to the air receiver.

Reciprocating compressor multistage ideal conditions for multi stage compressors. The main difference between single and two stage compressors is the number of times that air gets compressed between the inlet valve and the tool nozzle. The simplest compressor designs feature a single cylinder chamber arrangement. If we required discharge air pressure above 85 kg cm then four stage air compressors are useful.

Multistage compression refers to the compression process completed in more than one stage i e a part of compression occurs in one cylinder and subsequently compressed air is sent to subsequent cylinders for further compression. The working principle of multistage air compressor is same as double stage air. In addition multistage compressors run much longer on cycles than one stage units which cycle on and off more frequently. We know that pv n c where n is the polytropic compression index.

Very high air pressure 250 bar and air volume flow rate is possible with. In my next article we will discuss the work done by and reasons for using multi stage air compressors.
