Analysis of common problems of air compressors:

1. Exhaust temperature of a certain stage is too high:

(1) The intake and exhaust valves of the next stage are faulty or poorly installed or the valve plates and springs are damaged

(2) The piston ring of the next stage fails

2. The exhaust pressure of a certain stage is too low:

(1) The intake and exhaust valves of this stage are faulty, or poorly installed, or the valve leaf spring is damaged

(2) The piston ring of this stage fails

3. Exhaust temperature of a certain stage is too high:

(1) The intake air temperature of this stage is too high (2) The exhaust pressure of this stage is too high (3) The temperature of the cooling water drainage is too high

4. The oil temperature is too high: (1) The oil cooler fails (2) The bearing or bearing bush or slideway or oil pump is faulty

5. Drainage temperature is too high: insufficient water supply
