Multi Stage Air Compressor Diagram

Reciprocating compressor multistage ideal conditions for multi stage compressors.

Multi stage air compressor diagram.

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. For maximum compressor efficiency it is desirable to cool air after one stage using inter stage cooler. We know that pv n c where n is the polytropic compression index. 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. Reciprocating piston compressors use a cylinder to force air into a chamber where it is compressed. Reciprocating compressor diagram parts working multi stage compressor.

While straightforward this setup is limited in its efficiency and capacity for delivering high volumes of pressurized air. Advantages of reciprocating compressor. In addition multistage compressors run much longer on cycles than one stage units which cycle on and off more frequently. Piston type compressors are available in a wide range of capacity and pressure 2.

Thus we have seen the actual operation of an air compressor and its theoretical p v diagram. Practical understanding of multi stage compressor. The compressed air at the pressure p2 volume v2 and temperature t2 is delivered out of the compressor to the air receiver. The multi stage compressors are available with pressure up to 250 350 bar.

Very high air pressure 250 bar and air volume flow rate is possible with. The working principle of multistage air compressor is same as double stage air. A compressor operating at lower output consumes less electricity. Cvp 3 2 9 5 4 1 cvp n 8 7 6 l p.

If we required discharge air pressure above 85 kg cm then four stage air compressors are useful. The simplest compressor designs feature a single cylinder chamber arrangement. Single stage compressor. This discharge air pressure is achieved by a multi stage air compressor.

In single stage compressor entire compression of air takes place in single stroke of the piston. In a single stage compressor the air is compressed one time. For pressures exceeding 30 bar multi stage compressors are required. 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 normally use three stage reciprocating air compressors as a multi stage air compressor. In my next article we will discuss the work done by and reasons for using multi stage air compressors.
