Prerequisites and principles for adjustment of several operations in the refrigeration system of cold storage

Prerequisites and principles for adjustment of several operations in the refrigeration system of cold storage First of all, it is necessary to abide by the premise and principle of operation and adjustment, that is, the adjustment lever of the expansion valve must be adjusted in the middle position to keep it in the factory state, and it cannot be arbitrarily adjusted in the future. The mobilization changes the opening degree, and it is impossible to tell whether it is because the opening degree is too large or too small, or because the system is added more or less, or because the refrigerant is missing due to leakage. By maintaining the factory state of the expansion valve, the working conditions can be identified and judged whether the system has added more or less refrigerant, or lacked refrigerant due to leakage. Normally, the superheat degree of the expansion valve can only be adjusted slightly. 'J:? + E (k: d. W7 D8 N Under no circumstances should frost appear on any part of the compressor body! This is also a sign to measure and identify whether the compressor and system are normal. The frost on the compressor body indicates that the compressor is running at a wet stroke (with liquid). At this time, the compression efficiency will be greatly reduced. In severe cases, there is no compression capability, and the energy efficiency is extremely poor; because of the low operating temperature, increased lubrication The viscosity of the oil affects the lubrication, and it is easy to damage the machine parts or the compressor. Frosting timing of cold storage: when the storage temperature is above 0 degrees, no frosting phenomenon should occur in any part of the entire system! Only when the storage temperature is below 0 degrees, the frost-covered parts can gradually appear. The frost of the system is the discharge pipe of the expansion valve, and then slowly extends to the evaporator. After the entire evaporator is completely frosted, the air return pipe (suction pipe) is finally reached until the suction valve of the compressor. . This is also to measure whether the operation and adjustment of the system are in place
