Piston ammonia gas compressor fault rectification

Troubleshooting Steps for a Piston-type Ammonia Gas Compressor That Won't Start Properly:

Firstly, check if the issue is caused by low supply voltage or poor motor circuit connections. If it is confirmed that the grid voltage is low, wait for the grid voltage to normalize before restarting. If the problem is due to poor contact in the circuit, inspect the connections related to the motor and make the necessary repairs.

(2) Inspect for exhaust valve leakage: If the exhaust valve is cracked or not sealed properly, it can lead to excessive pressure inside the crankcase, resulting in difficulty in starting. Replacing the exhaust valve and gasket will resolve the issue.

(3) Inspect whether the energy regulation mechanism is malfunctioning. Mainly check for blockages in the fuel supply line, low pressure, or stuck oil pistons, and repair according to the cause of the fault.

(4) Inspect the temperature controller for damage or misalignment; adjust the temperature controller if misaligned; repair or replace if damaged.

(5) Check if the pressure relay is malfunctioning. Simply repair the pressure relay and reset the pressure parameters.
