3 Stage Air Compressor Diagram

After 3 months the motor burnt out.

3 stage air compressor diagram.

In a two stage compressor the air is compressed twice for double the pressure. Fig shows various parts of three stage v type reciprocating air compressor with the receiver air tank. In a single stage compressor the air is compressed one time. Reciprocating piston compressors use a cylinder to force air into a chamber where it is compressed.

The compressed air at the pressure p2 volume v2 and temperature t2 is delivered out of the compressor to the air receiver. In my next article we will discuss the work done by and reasons for using multi stage air compressors. The red wire from the 3 phase is only connected to the motor. 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.

The pressure switch is connected to the electric motor. We are using a 3 phase 240 volt system and hooking up to an air compressor. The black and blue wires from the 3 phase are connected to the pressure switch and then connected to the motor. In a three stage compressor the air will go into the first intake and be compressed before traveling over a cooler.

In my last article we discussed the limitations of a single stage air compressor and the problems associated with it.

The simplest compressor designs feature a single cylinder chamber arrangement. The trade off between 3 and 4 stage compressors is one of mechanical complexity vs energy efficiency.

The compressor features an oil lubricated pump with three cast iron cylinders a 1 piece cast iron crankcase and 12 in cast iron flywheel. But just cooling the compressed air delivered out of each stage to near atmospheric temperature leads to increased overall operating efficiency and overcomes plenty of mechanical problems associated with the compressor. Thus we have seen the actual operation of an air compressor and its theoretical p v diagram. Next the air goes into an intermediate stage compressor during which it is heated as a natural byproduct.

3 stage vs 4 stage air compressors. This minimizes the heat that has accumulated through the compression process and lets it get close to room temperature. Single stage air compressor provides high air flow with has 14 scfm at 90 psi and 155 psi max working pressure giving the user optimum tool performance. When the desired pressure in the air tank is reached it stops the motor and hence the compressor.

A 3 stage compressor is less mechanically complex than a 4 stage compressor. While straightforward this setup is limited in its efficiency and capacity for delivering high volumes of pressurized air.
