Compressor airflow decreases
Thread Content
The compressor in our unit is a reciprocating compressor. Starting from yesterday, the gas flow rate began to decrease gradually, dropping from 64,000 to 60,000, and then stabilized. Upon inspection, one of the outlet valves of the compressor was found to be slightly warm. Could it be a problem with the valve? What other issues could there be? Thank you
The possible reasons are: 1. Valve issue； 2. Internal leakage of the return valve ； 3. Piston ring leakage ； 4. Packing leakage.
It is likely caused by a faulty and stuck air valve. The ultimate effect of a stuck air valve is the same as that of a unloader operating.
The answer on the 2nd floor is quite detailed; please check the inlet filter as well.
The main cause of this phenomenon is a valve failure; nothing else needs to be considered. Only consider other reasons if there is a sudden and significant drop in traffic.
Based on the owner’s description, it is more likely that the exhaust valve with a slightly higher temperature is leaking. Shut down the machine, clean the valve or replace the valve assembly, and then try starting the machine again.
It’s obviously a problem with the air valve; this kind of thing happens often
(1) The intake valve is not sealed properly. (2) The exhaust valve is not sealed properly. (3) Wear or damage to the piston rings. (4) Leakage of the sealing packing. (5) The safety valve is not tight. (6) Local abnormal leakage. (7) The intake pressure is too low.
It’s a problem with the air valve; the valve disc might be damaged, which is affecting performance.
This kind of issue is usually related to the valve, but it could also be a problem with the piston seal or the piston rod seal
There is a problem with the air valve, and the piston rings may also be worn, affecting the air inflation volume
According to the poster, it’s likely a problem with the valve; an increase in intake temperature can also lead to poor compression performance by the compressor. Large gaps in the piston rings or cylinders may likewise affect the compressor’s compression capacity. Of course, it’s also important to pay attention to cooling between the different sections of the compressor.
The reasons might be； 1 Increase in the temperature of the inlet gas 2 Leaks in the pipes 3 Damaged piston rings or leaking gas valves
