Multi Stage Air Compressor Diagram

The simplest compressor designs feature a single cylinder chamber arrangement.

Multi stage air compressor diagram.

The working principle of multistage air compressor is same as double stage air. While straightforward this setup is limited in its efficiency and capacity for delivering high volumes of pressurized air. If we required discharge air pressure above 85 kg cm then four stage air compressors are useful. The compressed air at the pressure p2 volume v2 and temperature t2 is delivered out of the compressor to the air receiver.

Single stage compressor. In single stage compressor entire compression of air takes place in single stroke of the piston. This discharge air pressure is achieved by a multi stage air compressor. Reciprocating compressor multistage ideal conditions for multi stage compressors.

Advantages of reciprocating compressor. 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. A compressor operating at lower output consumes less electricity. We normally use three stage reciprocating air compressors as a multi stage air compressor.

Single stage cycle. In my next article we will discuss the work done by and reasons for using multi stage air compressors. In multi stage compressor compression takes in stages. 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.

For pressures exceeding 30 bar multi stage compressors are required. 8 1 5 6 1 1 5 11 1 1 n n p p vp n n w delivery temperature n n p p tt 1 1 5 15. Reciprocating compressor diagram parts working multi stage compressor. Piston type compressors are available in a wide range of capacity and pressure 2.

The multi stage compressors are available with pressure up to 250 350 bar. In addition multistage compressors run much longer on cycles than one stage units which cycle on and off more frequently. Very high air pressure 250 bar and air volume flow rate is possible with. Cvp 3 2 9 5 4 1 cvp n 8 7 6 l p.

Thus we have seen the actual operation of an air compressor and its theoretical p v diagram. Practical understanding of multi stage compressor. 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 two stage compressor initial compression takes place in the low pressure cylinder.

We know that pv n c where n is the polytropic compression index. Reciprocating piston compressors use a cylinder to force air into a chamber where it is compressed.
