8 Simple Maintenance Knowledge of Combined Cold Storage

Apr. 08, 2020

In the process of using cold storage, we will inevitably have some small faults. If we can troubleshoot a little, we can eliminate the faults in a short period of time, which will reduce losses. The chiller Cold Room factory will introduce you to some combination of cold storage maintenance knowledge!

1. The initial operation unit of the cold storage equipment: the oil level and oil return condition of the compressor and the cleanliness of the oil should be constantly observed. If the oil is dirty or the oil level drops, it should be resolved in time to avoid poor lubrication.

2. The combined cold storage is not cooled or has a poor cooling effect. Check whether the condenser of the refrigerator is dirty. Check whether the evaporator in the store is too thick. Check whether the refrigerant is leaking (apply soapy water to the pipe connection, if there are bubbles, it means the refrigerant is leaking). And ask the combined cold storage engineering staff to replenish the refrigerant and deal with the leakage. Check whether the seal of the combined cold storage door is intact and eliminate it. Check whether the refrigerator in the combined cold storage is working. Check whether the parameter setting of the computer controller of the cold storage is correct and reassemble the cold storage door installation. Check whether the controller of the cold storage is malfunctioning and replace it. Check whether there are enough gaps in the stacking items and clear them.

8 Simple Maintenance Knowledge of Combined Cold Storage

3. Always observe the operating state of the compressor of the cold storage equipment, check its exhaust temperature, and pay special attention to the operating state of the system when changing seasons, and adjust the liquid supply and condensation temperature of the system in time.

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

5. Normally, the operating state of the compressor should be observed by observing the change of the instrument, listening to the sound of the machine running, and touching the temperature change of the machine. The compressor should be repaired or replaced in time if it finds that the compressor has a gas string.

6. The light in the warehouse is not on. Please check whether the switch is malfunctioning and the bulb is damaged. Cut off the power supply during the inspection, and pay attention to the waterproof of the lamp when installing the lampshade.

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

8. We should implement regular repairs and daily maintenance to maintain the efficiency of the compressor operation.
