    Daily cold storage system maintenance method

    Daily cold storage system maintenance method For large-scale refrigeration equipment such as cold storage, we should usually do daily inspection and maintenance in order to quickly eliminate the abnormal operation of the cold storage, thereby reducing the inconvenience and loss caused by the cold storage. How to maintain For large-scale refrigeration equipment such as cold storage, we should usually do daily inspection and maintenance in order to quickly eliminate the abnormal operation of the cold storage, thereby reducing the inconvenience and loss caused by the cold storage. How to maintain refrigeration systems such as cold storage and fresh storage. 1. The compressor suction temperature in the refrigeration system is 5-15 degrees Celsius higher than the evaporation temperature; 2. The oil temperature of the refrigeration crankcase cannot exceed 70 degrees Celsius; 3. The oil pressure of the refrigeration compressor is higher than the suction pressure, which is about 0.12-0.3Mpa; 4. Corresponding to the evaporation pressure of the suction pressure box of the refrigeration compressor; 5.The exhaust temperature of the refrigeration compressor r22 system must not exceed 150 degrees Celsius, and the maximum r12 system cannot exceed 130 degrees Celsius; 6. The refrigeration compressor of the cold storage should not have obvious knocking sound; 7. The heat of all parts of the body of the cold storage refrigeration compressor unit shows normal; 8. Always pay attention to the cooling water temperature and cooling water volume. The condenser inlet water temperature is preferably 2 to 5 degrees Celsius lower than the outlet water temperature. 9.The condensing pressure should not exceed the range of the discharge pressure of the refrigeration compressor; 10. 10.Always pay attention to the oil return of the compressor crankcase oil level and the oil separator;
