1. The noise caused by the imbalance of the impeller of the Centrifugal pump Wholesale Price pump. Some pumps have been used for a long time. The impeller is in operation or is damaged by debris sucked into the pump cavity or other reasons that cause the impeller to lose its balance. Top-heavy and light-footed. At this time, when the motor is running at a high speed, the bearing strength of the motor bearing will be different, which will cause noise. At the same time, the motor shaft will also be affected by the unbalanced impeller, which will cause noise.

2. Noise caused by bearing damage. Some customers install the water pump outdoors and use it without any shelter. Rainwater will be sucked from the motor fan cover by the fan blades. If it invades into the bearing chamber of the motor rear cover, the bearing will be oxidized. Rust, the bearing balls are no longer smooth, and mechanical noise will be emitted. If it is installed indoors, this problem generally does not occur, but there will be another situation. If the mechanical seal is not replaced in time between damages, use it as it is. If there is no shutdown, the mechanical seal will lose its sealing effect and the pump will run. The pressure in the middle pump cavity causes the water in the pump body to spray out. The water retaining ring on the motor shaft can protect the motor bearing from water intrusion in a short time, but the water will be damaged after more and more water sprays into the bearing chamber. bearing.
3. The noise of Centrifugal pump Wholesale Price caused by improper installation should be flat, stable, and firm during installation. Flat means level. When the pump is installed, the foot should be kept level and not inclined. Steady means it should be stable and not loose and swaying. , Sturdy means that the installation foundation must be solid and stable, and one side cannot be on the ground and the other side cannot be suspended.
