Multi Stage Air Compressor 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.

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. Advantages of reciprocating compressor. Single stage compressor. Practical understanding of multi stage compressor.

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. If we required discharge air pressure above 85 kg cm then four stage air compressors are useful. Cvp 3 2 9 5 4 1 cvp n 8 7 6 l p.

In a single stage compressor the air is compressed one time. In a two stage compressor the air is compressed twice for double the pressure. In two stage compressor initial compression takes place in the low pressure cylinder. In single stage compressor entire compression of air takes place in single stroke of the piston.

Single stage cycle. We normally use three stage reciprocating air compressors as a multi stage air compressor. This discharge air pressure is achieved by a multi stage air compressor. 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.

While straightforward this setup is limited in its efficiency and capacity for delivering high volumes of pressurized air. The simplest compressor designs feature a single cylinder chamber arrangement. In multi stage compressor compression takes in stages. 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.

For pressures exceeding 30 bar multi stage compressors are required. In my next article we will discuss the work done by and reasons for using multi stage air compressors. We know that pv n c where n is the polytropic compression index. The multi stage compressors are available with pressure up to 250 350 bar.

Reciprocating compressor diagram parts working 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 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.

A compressor operating at lower output consumes less electricity. Thus we have seen the actual operation of an air compressor and its theoretical p v diagram.
