Common faults and causes of compressors

Common faults and causes of compressors Common compressor failures are as follows: 　　L. The compressor cannot start normally 　　 The power supply voltage is too low, the motor circuit is poorly connected, or the exhaust valve is leaking, resulting in too high pressure in the crankcase. The energy regulation mechanism has failed. 　　 2. The compressor starts and stops frequently 　　The steam leakage of the exhaust valve makes the high and low pressures balance, resulting in too high inlet pressure or too small temperature relay amplitude difference. 　　 3. There is no oil pressure after the compressor is started or the oil pressure cannot be reached during operation The oil pump pipeline system is leaking or the pipeline is blocked, the oil pressure regulating valve is too large or the valve core is off, the crankcase is too low or there is ammonia in the tank, the oil pump does not enter the oil, or the oil pump may be seriously damaged The gap is too large. 　　 4. The oil pump is not pressurized 　　 The parts of the oil pump are severely damaged, causing the gap to be too large, or the oil pressure gauge is inaccurate, and the pointer is malfunctioning. 　　 5. The lubricant in the crankcase foams 　　The lubricating oil is mixed with a large amount of ammonia liquid. When the pressure is reduced, the ammonia liquid causes foaming; the crankcase is filled with too much oil, and the connecting rod is driven by the lubricating oil. 　　 6. Compressor oil consumption is too large 　　 The oil ring is severely worn, and the assembly gap is too large; the oil ring is installed reversely, and the locking port of the ring is installed on a vertical line. The gap between the piston and the cylinder is too large; the temperature of the exhaust steam is too high, so that the lubricating oil is taken away by the airflow in large quantities.
