The sewage pump with mixing is very noisy

The sewage pump with mixing device is mostly used to suck sewage pits with more particles, such as slurry water in industrial production and urban underground sewage pits. The mixing device can float and discharge the precipitated foreign matters. Compared with the traditional sewage pump, it has higher treatment efficiency and medium overcurrent. However, recently, some customers have reported that the sewage pump with mixing device is very noisy, EVP pump industry provides relevant solutions.
The automatic mixing sewage pump is a submersible sewage pump. Although the mechanical operation itself will produce a certain amount of noise, because the operation is carried out under the liquid and the noise cannot be transmitted to the ground too much, the noise perceived by human beings should be limited. If the noise is unbearable in the actual process of using the pump, it is recommended to put forward the pump and carry out the following maintenance and treatment.
1. First check the pipeline system, mainly to ensure that the pipeline has a separate support frame, and all connections are fastened without looseness. If necessary, install damping devices to alleviate the noise caused by vibration;
2. Confirm the historical maintenance records of the sewage pump and check whether anyone has changed the factory structure and configuration components of the pump. Some users will modify the pipe size of the sewage pump to make the flow meet the transportation standards. This behavior will lead to the imbalance of water absorption and output, resulting in severe noise and shaking. If it is really necessary to change the configuration and internal structure of the sewage pump under special transportation conditions, it is recommended to contact the manufacturer and arrange professional technicians to implement it;
3. In addition to the behavior of modifying the pump structure by themselves, some users also replace the supporting motors of the original factory. Some newly replaced motors may have poor performance or mismatch with the pump power, resulting in unstable current during operation, pulse and noise.
The above content briefly introduces the relevant reasons and treatment measures for the high noise of the sewage pump with mixing. Such matters can be avoided in the actual process of using the pump, which only requires the operator to pay more attention. If you want to know more pump information such as screw pump and multi-stage pump, you are welcome to continue to pay attention to EVP pump industry.
