During the operation of the low-temperature chiller, there will be a liquid hammer phenomenon, and after a detailed analysis of the cause of the failure, we also have a corresponding solution. The specific operations are as follows:
In fact, the measures to solve the liquid shock failure of the low-temperature chiller can be carried out before the equipment is turned on. For example, the oil cavity of the compressor in the chiller can be preheated for a long time, so as to effectively avoid the refrigerant Accumulation in lubricating oil can prevent the occurrence of liquid hammer to a certain extent.
In addition, the protection of the flow of the water system of the chiller is also one of the key measures, so that the compressor can be protected when the water flow is not enough, so as to avoid the failure of the chiller. When designing the chiller pipeline, it would be better if the liquid refrigerant can be prevented from entering the compressor when it is turned on, especially in the refrigeration system with a relatively large charge.
In addition, in the normal operation of the equipment, it is necessary to strengthen its inspection and maintenance to avoid serious failures.
