8 simple maintenance common sense of combined cold storage you must understand

We will inevitably have some small failures in the process of using the cold storage. If we can do a little simple troubleshooting, we can eliminate the failures in the shortest time and reduce losses. The following editor of okmarts.com will introduce you some knowledge of combined cold storage maintenance!

　　 1. Initial operation of cold storage equipment: Always observe the oil level and return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, solve it in time to avoid poor lubrication.

　　 2. The combined cold storage is not cooling or the cooling effect is poor. Check whether the condenser of the refrigerator is dirty. Check whether the frost is too thick on the evaporator in the warehouse. Check if the refrigerant is leaking (coat the pipe connection with soapy water, there are bubbles that indicate refrigerant leakage). And ask the engineer of the combined cold storage to supplement the refrigerant and deal with the leakage. Check whether the sealing of the combined cold storage door is intact and eliminate it. Check whether the refrigerator in the combined cold storage works. Check whether the parameter setting of the computer controller of the cold storage is correct and re-assemble the cold storage door installation. Check whether the controller of the cold storage is malfunctioning and replace it. Check whether there are enough gaps for the items stacked in the warehouse and clear them.

　　3. Frequently observe the operating status of the heart compressor of the cold storage equipment, check its exhaust temperature, and pay special attention to the operating status of the system during seasonal operation, and adjust the system's liquid supply and condensation temperature in time.

　　4. The combination cold storage door starts frequently or does not start for a long time, or when it does not stop after a long time, or the storage temperature is not reached, it will stop. A. Check whether there is dirt on the condenser. Poor heat dissipation will cause the condensing pressure of the refrigerator to be too high. In order to protect the compressor, the machine will stop running under the action of the pressure controller. After the heat dissipation is good, press the pressure controller. The black reset button, the machine will automatically resume operation. B. The parameter setting of the controller is wrong, just reset it. C. The refrigeration is not good, please refer to fault 2. D. The temperature control fails. E. The electrical appliance is damaged.

　　5. The operating status of the compressor should be observed by observing the changes of the instrument, listening to the sound of the machine, and touching the temperature change of the machine. If the compressor is found to have gas leakage, it should be repaired or replaced in time.

　　6. ​​The lighting in the library does not light up. Please check if the switch is malfunctioning and the bulb is damaged. When checking, cut off the power supply and pay attention to the waterproof of the lamp when installing the lamp cover.

　　7. The combination cold storage door is not closed tightly. Please adjust the hinge on the door and the distance between the door lock and the storage body.

　　 8. We should implement regular maintenance and routine maintenance to maintain the high efficiency of compressor operation.
