How to start and shut down a reciprocating compressor when both the outlet valve and check valve are leaking?
Thread Content
Dear sea friends: When the outlet valve and check valve of a reciprocating compressor leak severely (severe air leakage occurs as soon as the inlet and outlet manual valves are opened), how should it be started up and switched? I would appreciate your advice.
If the air valve leaks, the system operates under load from the start, which can easily cause fluctuations in system pressure; it is best to repair or replace the air valve.
Leaks in the air valve and check valve are both abnormal; they need to be repaired. If the check valve leaks, it’s a bit better; when pressurizing the tank, open the outlet valve slowly first to build up pressure, and then open the inlet valve once the pressure reaches the desired level. It’s best to repair the air valve before cutting it off; as mentioned above, a leaky air valve is equivalent to imposing extra load on the system. Forcing a cut-off will cause large fluctuations in system pressure, which has a significant impact on operations
Like, like! Fate, one can meet it even here.
I agree with you; it’s definitely the safest and most seamless approach to repair it first before shutting down the machine. However, in the production of such devices, it is inevitable that operating machines may fail and require shutdown for maintenance; at the same time, there are issues where the exhaust valves and check valves of the backup machines leak, forcing a shutdown as well. This is why the above questions arise.
