How should cold storage refrigeration equipment be repaired?

To complete the maintenance of the semi-closed refrigeration compressor, it is necessary to check whether the gap between the parts of the semi-closed refrigeration compressor is in the normal range. If it is too large or too small, it will cause the gas transmission coefficient to change so as to weaken the refrigeration effect. The second is to check the following aspects.

1. The cold storage unit should carefully observe the oil return situation of the compressor during the initial operation, and keep it clean. If the oil surface is not clean enough or the oil surface is falling, it is necessary to refuel or replace the oil in time. This can avoid poor lubrication

2. Judge the sound of cold storage equipment. Listen carefully to the running sound of the water pump, cooling tower, compressor, fan and other equipment. If it does not conform to the routine, it should be repaired in time. The maintenance site can be referred to the vibration situation of the compressor, exhaust pipe and foundation.

3. Often observe the operation of compressor equipment, check the exhaust temperature, in the seasonal change, when the temperature difference is large, special attention should be paid to the operation. If any exception occurs, check and adjust the condensation temperature and liquid supply

4. Check whether the water pump works properly. Whether the moldy switch is effective. If an exception occurs, handle it in time

5. For water cooling equipment, it is necessary to check the turbidity of cooling water frequently. It is necessary to replace the cooling water frequently. And check the water supply system running, taking, dripping, leakage and other conditions exist.

6. Overhaul and maintenance of cold storage refrigeration compressor: In general, the refrigerated oil and filter dryer should be replaced once after the cold storage equipment runs for 30 years. Change the situation half a year later.

There are many cold storage refrigeration equipment, among which the core product is semi-closed refrigeration compressor, compressor types on the market are also many, in the choice of consumers or according to the specific needs of the choice, and do a good job in the daily use of maintenance work.
