How to solve the pump noise？

Speaking of pump believe that will not be unfamiliar, it is often used in daily life items. In the process of using the pump, often there will be a lot of noise, if not dealt with in time, the use of later will also bring a certain impact, so we all want to know how to solve the pump noise? How to deal with it?
In fact, there are many reasons for the noise generated when the pump is running, such as unreasonable installation, air in the pump and dirt mixed with the noise factors, which are often encountered is due to cavitation vibration and noise. And in addition, the pump noise through the pipeline, pipeline support, building entities and so on these to propagate, the need for vibration reduction and noise control.

For pump vibration reduction measures:
(1) need to choose a low speed, low noise, and low energy pump, not only can reduce the noise, but also make the pump problem less.
(2) It is necessary to reduce the vibration of the water pump set, and install the vibration isolator or elastic liner material under the base.
(3) the inundation depth of the suction port can not be too high or too low, and the connection with the suction pipe needs to be sealed. For these details, if not treated, it is easy to lead to water flow into the air and cause cavitation noise.
(4) The connection between the suction pipe and the outlet pipe needs to use a soft connection device.
(5) and then the pump installation design needs to be reasonable, need to meet the pump allowed cavitation allowance standard.

For other pump noise problems and solutions:
(1) For the pump with imperfect foundation, it is necessary to reinstall it according to the basic requirements.
(2) for the impeller rotation imbalance caused by noise, it is necessary to check the impeller rotation balance, if necessary to replace the impeller.
(3) if there is dirt and air mixed in the pump, it is necessary to remove the dirt in the pump, and then to seal, so that the pump does not accumulate air.

In order to facilitate the use of water in daily life, are generally used to pump. In the process of using the pump, there are many reasons for the pump noise, if you want to solve the problem of noise, you can try through the above ways, so as to ensure that the pump is in the normal range, to avoid more trouble.
