Common problems of fruit preservation display air curtain cabinet
Release Time:
2023-04-06
Fruit preservation-air curtain cabinet is not unfamiliar to everyone, especially in summer, it can be seen almost everywhere. Since it is so widely used and the usual utilization rate is relatively high, it is inevitable that some products will fail. If there is a failure, it may lead to its inability to use, which will bring some unnecessary economic losses to people.
Fruit preservation-air curtain cabinet is not unfamiliar to everyone, especially in summer, it can be seen almost everywhere. Since it is so widely used and the usual utilization rate is relatively high, it is inevitable that some products will fail. If there is a failure, it may lead to its inability to use, which will bring some unnecessary economic losses to people.
I don't know if you have encountered it. Sometimes when touching the cabinet, there will be an electric shock feeling, which is the leakage of the fruit preservation-air curtain cabinet. Elimination method: Use a multimeter to measure the leakage and check it by section method. When the compressor is powered on and running alone, check whether the entire cabinet is charged due to the leakage of the compressor. Statically detect the compressor terminal, and pay attention to the lead plug part in the motor winding. If there are ignition marks with the casing, it indicates that there is leakage. The method of replacing the terminal part together with the surrounding part of the shell is adopted. After installing the body, power it on to make it run, check whether there is any leakage phenomenon. After the various indicators of the compressor are normal, put it back on the base of the cabinet and connect the pipeline., leak detection, evacuation, and filling with an appropriate amount of refrigerant to restore normal operation.
Also, after the power is turned on, the air switch on the cabinet is suddenly disconnected. There are generally two situations: one is that the compressor fails; the other is caused by unstable voltage. Troubleshooting method: Check whether the compressor of the first-stage refrigeration system is damaged. If it is damaged, it will cause a short circuit and cause power protection. You can replace the accessories. If there are no original accessories, you can replace the compressor with a considerable power after calculation, weld the pipeline well, and after pressurizing to check the air tightness of the pipeline, vacuum and add refrigerant, and then turn it on to check whether it is normal. The fault may also be caused by the unstable power supply. Because the first stage starts first, the damage is usually in the first stage. In this case, as long as the delay regulated power supply is installed, the fault will not occur again.
Another more common phenomenon is that the internal temperature of the fruit preservation-air curtain cabinet has stopped working before it reaches the temperature set by us on the thermostat. This phenomenon will also directly affect the freshness of the items in the cabinet. Troubleshooting method: Although the cabinet has not reached the set temperature, the panel display temperature has reached the set temperature. This is due to damage to the thermistor that detects the temperature, and accessories need to be replaced. If there are no original accessories, a temperature control system can be reinstalled to eliminate the fault.
