Multi Stage Air Compressor Diagram

The compressed air at the pressure p2 volume v2 and temperature t2 is delivered out of the compressor to the air receiver.

Multi stage air compressor diagram.

Single stage compressor. Single stage cycle. Very high air pressure 250 bar and air volume flow rate is possible with. 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.

We know that pv n c where n is the polytropic compression index. While straightforward this setup is limited in its efficiency and capacity for delivering high volumes of pressurized air. Reciprocating compressor multistage ideal conditions for multi stage compressors. A compressor operating at lower output consumes less electricity.

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 two stage compressor the air is compressed twice for double the pressure. For pressures exceeding 30 bar multi stage compressors are required. Practical understanding of multi stage compressor.

In multi stage compressor compression takes in stages. We normally use three stage reciprocating air compressors as a multi stage air compressor. The simplest compressor designs feature a single cylinder chamber arrangement. For maximum compressor efficiency it is desirable to cool air after one stage using inter stage cooler.

Reciprocating piston compressors use a cylinder to force air into a chamber where it is compressed. Piston type compressors are available in a wide range of capacity and pressure 2. Cvp 3 2 9 5 4 1 cvp n 8 7 6 l p. In two stage compressor initial compression takes place in the low pressure cylinder.

If we required discharge air pressure above 85 kg cm then four stage air compressors are useful. The multi stage compressors are available with pressure up to 250 350 bar. Reciprocating compressor diagram parts working multi stage compressor. Thus we have seen the actual operation of an air compressor and its theoretical p v diagram.

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. In my next article we will discuss the work done by and reasons for using multi stage air compressors. 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. Advantages of reciprocating compressor.
