What should I do if the pump flow in the industrial chiller is faulty?

The flow rate of the pump must be appropriate. Too large or too small will have an impact on the operation of the industrial chiller.


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


1. When the pump flow is too small, the pump flow and lift data should be observed to see if it matches the pump. This situation occurs when some products produced by chiller manufacturers fail.


2. If the flow rate and head of the pump match the specifications of the pump required by the industrial chiller, then it should be checked whether the pump is used for a long period of time, whether the pump is excessively worn or damaged, and whether the pipe is damaged or leaked. . Of course, it may be that it has not been used for a long time, the parts are rusted, oxidized, and there may be foreign matter inside the water pump and inside the water pipe.


3. Some people think that the reverse rotation of the pump motor will also cause the flow to be too small and the engine to be damaged. However, this is not the case. The motor is reversed at a certain speed and will not cause damage to the pump or motor. Small is basically not caused by reversal, because in the case of reversal, the pump is difficult to effluent.


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


Second, the reasons and solutions for excessive pump flow


The flow rate of the pump is too large. In addition to the problem of setting operation data of the chiller system, it should also be considered whether the parameters such as the head and flow of the chiller pump are relatively large and exceed the normal demand range. This is believed to be a chiller. The problem with the manufacturer is that the pumps that do not match are used in the chiller.


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