Compressor
Thread Content
Currently, the inlet and outlet pressures as well as the temperature at the first stage of the compressor are normal. The inlet pressure at the second stage is normal, but the outlet pressure is low (0.76 MPa); the temperature there is normal. The inlet pressure at the third stage is 0.76 MPa and the temperature is also normal, yet the outlet pressure shown is 0. There is a change in temperature in the cooler located between the third and fourth stages – the temperature near the third stage is 69.7, while it is 20 near the fourth stage. The inlet pressure at the fourth stage is 0 and the temperature there is normal; the outlet pressure at the fourth stage has not been checked. What could be the cause?
First, check if there is a problem with the pressure gauge. Then check the third-stage gas valve and eliminate the issue step by step
