Maintenance knowledge of cold storage equipment

Maintenance knowledge of cold storage equipment:
1. Regularly check and confirm whether the power supply voltage meets the requirements. The cold storage voltage should be 380 V ≤ 10% (three-phase four-wire). When the cold storage equipment is not used for a long time, the total power of the cold storage should be cut off. source, and ensure that the cold storage equipment is not contaminated by moisture, ash and other substances.
2. The condenser on the refrigeration device is susceptible to contamination and should be cleaned regularly according to the actual situation. In order to maintain good heat transfer effect, good heat dissipation effect and good cooling effect, the surroundings of the refrigeration unit should not be cleaned. Stacking clutter
3. The electrical equipment of the cold storage equipment should be kept away from moisture to avoid electric shock accidents due to leakage.
4. The hinges, handles and door locks of the cold storage door should be lubricated regularly according to the actual situation.
5. Maintenance of electrical equipment of refrigeration equipment should be performed by individuals or personnel who know how to use electricity. Any maintenance must cut off the power supply to ensure safety.
6. The vibration of the refrigerator should be avoided during operation. This will not only increase mechanical wear, but also cause the unit connecting pipe to loosen or break. If abnormal noise is found during the operation of the machine, it should be stopped for inspection and elimination before operation. The protection function of the refrigeration compressor unit is pre-set and does not require adjustment. When the insulation layer is damaged or the steam insulation layer and the top waterproof layer are not tightly connected, the water vapor in the high-temperature, high-humidity air outside the cold storage in summer moves from the outdoor high-temperature side to the cold storage under the power of the water vapor pressure difference.
7. Regularly inspect the cold storage structure. Civilian cold storage walls are composed of cement mortar surface layer, brick exterior wall, surface layer, steam insulation layer, polyurethane insulation layer and protective layer. This causes a large amount of condensation or frost layer to be generated on the inner layer of the cold storage structure, affecting the cold storage. service life. At the same time, the generation of cold bridges causes a large amount of waste of cooling capacity and increases the workload of the refrigeration unit. The storage plate assembly gap of the prefabricated cold storage enclosure structure is too large and needs to be sealed with glass glue or foaming agent to ensure that the surface of the enclosure structure is dry and the structure is intact.
