Causes and solutions for flow failure of water pump in industrial chillers

Industrial chillers will inevitably have various types of failures during operation. Today, Chongqing Refrigeration Equipment Company mainly analyzes with you the failure of the pump flow in the industrial chiller. When the flow is too large or too small , What caused it, and how to solve this problem.

　　 The flow rate of the water pump must be appropriate, too large or too small will have a certain impact on the operation of the industrial chiller.

　　 One, the reason and solution of the pump flow is too small

　　 1. When the pump flow is too small, you should observe the pump flow and head data marked by the pump to see if it matches the pump. Some chiller manufacturers produce unqualified products that will cause this situation.

2. If the parameters such as the flow rate and head of the water pump match the specification data of the water pump required by the industrial chiller, then you should check whether the pump has a long service life, whether the pump is excessively worn or damaged, and whether the pipeline is damaged or leaked. . Of course, it is also possible that the parts have not been used for a long time, the parts have been rusted, oxidized, and the inside of the pump and the water pipe may be blocked by foreign objects.

3. Some people think that the reverse rotation of the water pump motor will also cause too little flow and engine damage, but in fact it is not the case. The reverse rotation of the motor at a certain speed will not cause damage to the pump and motor, but excessive flow. Basically, it will not be caused by reversal, because in the case of reversal, the water pump is difficult to discharge.

　　4. If the pump flow is too small, you should also consider whether it is the setting of the chiller system.

　　 2. Reasons and solutions for excessive pump flow

The flow of the water pump is too large. In addition to the problem of the setting and operating data of the chiller system, you should also consider whether the head, flow and other parameters of the chiller pump are relatively large and exceed the normal demand range. This problem is believed to be the chiller The manufacturer’s problem is that the unmatched pump is used in the chiller.

It is not advisable for the circulating water pump flow of industrial chillers to be too large or too small. Many users blindly pursue the pump flow, thinking that a large pump flow will make the chiller have a good cooling effect and a large cooling capacity, which can meet the cooling requirements. Otherwise, matching the excessively large cooling water circulation pump will inevitably increase the equipment cost of the industrial chiller unit, and the operating costs such as electricity bills will also increase. Excessive cooling water flow and pressure will also cause the water flow pipe resistance to increase and cause unnecessary The increase in energy consumption reduces the service life of the cooling water circulation pump and may cause many other failures.
