The core problem of compressor oper
Emergency solution for sudden wet stroke failure in refrigeration compressor operation
The refrigeration compressor suddenly encounters a wet stroke failure during operation, that is, after the failure appears, only a quick solution to the problem can avoid a series of more problems caused by the wet stroke. Earlier, we did not analyze this problem in detail. We usually solve it according to established experience. In fact, this failure of the refrigeration compressor can be treated separately according to the severity of the failure. Let’s share it together below. , After the wet stroke failure of the refrigeration compressor, how to deal with the ending problem according to the severity of the failure.
1. Emergency stop, close the suction valve of the refrigeration compressor, and close the liquid supply valve of the container with too high liquid level;
2. Set the compressor energy regulating valve to the "0" position and continue to stop the machine, so that the refrigerant in the machine is boosted and vaporized;
3. Manual cranking, observe the suction pressure gauge;
4. If the cranking is normal and the suction pressure is close to the normal working discharge pressure, set the compressor energy control valve to the "0" position and start the compressor; when there is no abnormal sound, increase the energy control valve 1st gear, pump out the refrigerant in the crankcase;
5. If the cranking is abnormal or the compressor makes an abnormal noise, the exhaust valve is closed, and the refrigerant in the crankcase is discharged through the exhaust multi-purpose channel;
6. Check the cause of the wet stroke and eliminate it;
7. Turn on again and observe whether there is a wet stroke phenomenon.
Therefore, the severity of the wet stroke of the refrigeration compressor determines whether manual cranking is required and the suction and discharge pressure gauges are observed.
