Razões para o som anormal da bomba horizontal multiestágio

1) The inlet runner is asymmetrical

The inlet channel of the pump has an important impact on the performance and noise of the pump. If the inlet channel is asymmetrical, the inlet flow of the pump impeller is uneven, and the vibration and wear of the multistage pump are adversely affected, resulting in a buzzing sound.

2) Improper installation

The base of the pump is not smooth, the fastening screw is loose, the pump shaft is not rotating and so on will also cause buzzing, you need to check whether the installation of the multistage pump is standardized, if there is a problem, timely maintenance or replacement parts.

3) The pump is damaged

When the pump is faulty, such as bearing damage, housing damage, etc., it is easy to appear buzzing, and it is necessary to contact professionals in time to repair or replace the pump.

4) One of the possible reasons for the humming sound of the pump shaft, when the multi-stage pump shaft is eccentric, it will cause the distance between the impeller and the fixed housing to be inconsistent, making the flow and velocity uneven, and then produce vibration and noise.

5) The pump is overloaded

Pump overload is also one of the reasons for the hum, under normal circumstances, the rated power of the pump is determined according to the load, if the load is too large during operation, it will produce a hum.

6) The impeller is not balanced

The impeller is a key component, and its balance has an important impact on the operation of the pump, if the impeller is unbalanced, it will cause the pump to buzz when running at high speed, and will also increase the vibration and wear of the pump, speeding up the aging and damage of the pump.
