3 Stage Air Compressor Diagram

The red wire from the 3 phase is only connected to the motor.

3 stage air compressor diagram.

Reciprocating piston compressors use a cylinder to force air into a chamber where it is compressed. In my next article we will discuss the work done by and reasons for using multi stage air compressors. The trade off between 3 and 4 stage compressors is one of mechanical complexity vs energy efficiency. In a single stage compressor the air is compressed one time.

The simplest compressor designs feature a single cylinder chamber arrangement. In a three stage compressor the air will go into the first intake and be compressed before traveling over a cooler. In a two stage compressor the air is compressed twice for double the pressure. A 3 stage compressor is less mechanically complex than a 4 stage compressor.

Fig shows various parts of three stage v type reciprocating air compressor with the receiver air tank. 3 stage vs 4 stage air compressors. Various parts of reciprocating compressors. Thus we have seen the actual operation of an air compressor and its theoretical p v diagram.

However given the same energy input the 3 stage compressor will output less compressed air than the equivalent sized 4 stage. The compressed air at the pressure p2 volume v2 and temperature t2 is delivered out of the compressor to the air receiver. After 3 months the motor burnt out. We used a pressure switch by square d part number 9013 fhg12mix.

Next the air goes into an intermediate stage compressor during which it is heated as a natural byproduct. 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. While straightforward this setup is limited in its efficiency and capacity for delivering high volumes of pressurized air.

The black and blue wires from the 3 phase are connected to the pressure switch and then connected to the motor. In my last article we discussed the limitations of a single stage air compressor and the problems associated with it. 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. We are using a 3 phase 240 volt system and hooking up to an air compressor.

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.
