What are the routine inspections for the maintenance of cold storage?

　　As the core facilities in the fields of cold chain logistics, food processing and medical storage, the stable operation of cold storage is directly related to the quality and safety of stored items. Doing routine maintenance inspection can not only prolong the service life of equipment, but also avoid economic losses caused by faults. Today, Lengdi combs the routine inspection contents of cold storage maintenance from the following five points. ​

　　The first is the inspection of refrigeration system. It is necessary to check the running state of the compressor regularly, listen to whether the running sound is stable and whether there is abnormal noise, and touch the shell temperature to ensure that it does not exceed the normal range; Check the cleanliness of the condenser and evaporator. If there is too much dust and oil on the surface, it will affect the heat exchange efficiency. It needs to be cleaned at least once a month, and can be washed with a high-pressure water gun or a special cleaner. In addition, it is necessary to check the tightness of the refrigerant pipeline, observe whether there are any leakage traces, and use a pressure gauge to detect the system pressure to ensure that it meets the rated standards of the equipment. If the pressure is abnormal, it is necessary to promptly check the leakage point and replenish the refrigerant. ​

　　Secondly, the electrical system inspection is related to the safe operation of the cold storage. It is necessary to regularly check whether the wiring terminals in the distribution box are loose, whether there is fever or oxidation, tighten the screws and clean up the dust, test the sensitivity of electrical components, such as whether the AC contactors and relays are normally engaged and disengaged, and whether the overload protection and short-circuit protection devices can be effectively triggered. At the same time, check the lighting system to ensure that the lamps in the warehouse are in good condition, and the emergency lighting can be started normally when the power is cut off, so as to avoid the dark environment from affecting the maintenance operation. ​

　　The third is to check the structure of the warehouse to ensure the thermal insulation performance of the cold storage. It is necessary to check the aging and cracking of the sealing rubber strip at the joint of the library board daily. If it is damaged, it should be replaced in time to prevent the leakage of cold energy. Check the closing and sealing performance of the library door to ensure that the door body is closely attached to the door frame, and the door hinges, handles and other accessories are flexible and available. If necessary, add lubricating oil. For the ground, check whether there are cracks and depressions. If heavy goods are stored, pay attention to the bearing capacity of the ground to avoid affecting the overall insulation effect of the cold storage due to structural damage. ​

　　Fourth, check the temperature and humidity to keep the storage environment stable. It is necessary to record the temperature in the warehouse regularly every day and compare the set values. If the temperature difference is too large, it is necessary to check whether the refrigeration system is abnormal. For the cold storage with humidity requirements, it is necessary to monitor the humidity change through a hygrometer and adjust the dehumidification or humidification equipment in time to prevent the stored items from deteriorating due to abnormal temperature and humidity. ​

　　Followed by safety inspection to eliminate potential risks. Regularly check whether the fire-fighting facilities in the warehouse, such as fire extinguishers and fire hydrants, are in good condition and effective, and whether the emergency passage is smooth. For the ammonia refrigeration cold storage, it is necessary to test the sensitivity of the ammonia leakage alarm device to ensure that it can alarm in time and start the emergency treatment system when it leaks, and at the same time check whether the equipment grounding is good, so as to avoid safety accidents caused by electric leakage. ​

　　In short, the routine inspection of cold storage maintenance needs to comprehensively cover key systems. Only through regular inspection and timely treatment can the cold storage run stably and safely for a long time and provide reliable guarantee for stored items.
