Horizontal multistage pump packing water leakage causes and treatment methods

In the case of serious water leakage at the root of the horizontal multistage centrifugal pump, it is easy to lead to unstable water pressure, the overall use effect of the pump can not reach the ideal standard, and there will be some hidden dangers of safety, and then analyze the causes and solutions of water leakage at the root of the multistage pump.

Horizontal multistage centrifugal pump root water leakage reasons:

1, The sealing may be aging, wear or damage, or it may be the connection at the root is loose and damaged

1, More wear, should be replaced.

2. If the disc is too loose, the gland should be pressed tightly.

3, The winding method is wrong, should be re-wound.

4, The centrifugal pump shaft bending, motor shaft and pump shaft is not coaxial, resulting in shaft offset disc root and water leakage, at this time should be corrected or replaced pump shaft, find a positive coupling, so that motor shaft and pump shaft coaxial.

Solution to water leakage at the root of horizontal multistage centrifugal pump:

1. Stop the water pump and disconnect it from the power supply.

2. Remove the packing parts of the centrifugal pump and check whether the status of the seals is normal. If the seal is aged or broken, it should be replaced with a new seal.

3, Check the pump pump body, if the pump body deformation should be replaced with a new pump body.

4. Check whether the installation of the packing is tight. If it is loose, the packing should be adjusted to ensure that the installation is firm.

5. Install the packing parts and tighten them with a wrench or other tools as required to ensure that there is no gap between the sealing parts and the centrifugal pump body.

6, Turn on the power supply, turn on the pump, and observe whether the water leakage of the pump has been solved. If the water leakage problem is still serious after the above treatment, it may be necessary to replace a new centrifugal pump.
