What are the causes of compressor overtemperature?

The main reasons are: 1. The cooling water volume for the four-cylinder engine is too low or not turned on； 2. The inlet temperature at the four sections is on the high side ； 3. The compressor is operating under overload conditions ； 4. Overpressure at the four outlet sections ； 5. Damage to the piston rings of the fifth-stage piston can cause gas from the fifth-stage outlet to leak into the fifth-stage inlet, which in turn can lead to overheating at the fourth-stage outlet. Others, please have experts add more.
What was said on the first floor is good; I’d add that it might be the valve that’s broken (there’s a problem with the air valve).
① A fault in the intake or exhaust valve in the lower section causes the discharge pressure to rise, increasing the compression ratio. ② The exhaust valve in that section is faulty; the gas that is expelled flows back into the system during inhalation, where it is compressed again. ③ The pre-cooler is not cooling properly.
Scaling on the condenser or oil cooler affects heat transfer
