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.

Piston type compressors are available in a wide range of capacity and pressure 2. Single stage cycle. Reciprocating compressor diagram parts working multi stage compressor. We normally use three stage reciprocating air compressors as a multi stage air compressor.

In a two stage compressor the air is compressed twice for double the pressure. If we required discharge air pressure above 85 kg cm then four stage air compressors are useful.

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

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. Practical understanding of multi stage compressor.

The working principle of multistage air compressor is same as double stage air. 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. The simplest compressor designs feature a single cylinder chamber arrangement.

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 maximum compressor efficiency it is desirable to cool air after one stage using inter stage cooler. 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.

Advantages of reciprocating 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. A compressor operating at lower output consumes less electricity. 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 compressor multistage ideal conditions for multi stage compressors. In two stage compressor initial compression takes place in the low pressure cylinder.
