The chiller is an indispensable product in industrial production now, and in long-term operation, the compressor of the chiller will overheat and cause the compressor to fail to run, that is, the chiller will fail. If you do not pay attention to maintenance, it will have a certain impact on the operation and service life of the chiller. Therefore, in order to solve the overheating failure of the chiller compressor, Shenzhen Simpson Refrigeration Technology Co., Ltd. will introduce the cold water to everyone. Of the compressor's overheating problem.
The causes of compressor overheating failure are as follows:
One: The compressor is overloaded and runs over current. The possible reasons are: too high cooling water temperature, excessive refrigerant charge, or non-condensable gas such as air in the refrigeration system, resulting in a large load on the compressor, which appears as an overcurrent and is accompanied by a high-voltage fault.
Two: The electrical fault causes the compressor of the chiller to run in overcurrent. If the three-phase power supply voltage is too low or the three-phase imbalance causes the current or the current of one phase to be too large; the AC contactor is damaged, and the contacts are ablated, resulting in excessive contact current or excessive current due to lack of phase.
3: The overheat protection module SSM of the freezer is damp or damaged, the intermediate relay is damaged, and the contacts are bad, which is manifested as an overheating fault when the machine is turned on, and the compressor cannot be started. If the unit's electronic board fails or communication fails, an overheating fault may be falsely reported.
Four: The chiller is not ventilated, and there is no ventilation distance for the entrance and exit seals of the chiller. The location of the chiller is very important. It must be installed in a well-ventilated place, and no debris can be placed around the chiller, otherwise it will affect the normal operation of the chiller.
The above are some of the reasons for the overheating of the chiller compressor. I hope it can help everyone. If the operator encounters the compressor overheating fault of the refrigerator again, he can solve the problem by using the method. If you need to know about the normal operation of the chiller, you can look at the methods and techniques to improve the chiller operation stability.
