Pump industry suppliers to tell you: reason mainly has the self-priming pump vibration which points

main reasons of the self-priming pump vibration are as follows:

1, due to the self-priming water pump equipment installation is not correct, some users in order to save energy the imbibition non-clog sewage pump directly to the random fixed self-priming pump factory batten bracket together with the self-priming pump on the ground in the import and export pipeline is used directly, and the user is the self-priming pump on the Angle iron welding stents, due to the hob is too single triangle is not only a small amount of solid self-priming pump base contact with Angle iron this method is not correct.

2, because when installing ZX self-priming pump coupling concentricity is not adjusted or the inside of the coupling rubber piece of wear and tear, cause a large self-priming pump vibration phenomenon appeared, at this time should be recalibrated coupling concentricity or replace the new rubber block and adjust good concentricity.

3, vacuum inside the pool water level dropped or the cause of the current is too fast, cause the self-priming pump suction let self-priming pump sound into the air when the abnormal phenomenon. Possibly is the reason why the self-priming pump bearing damage is cause of the self-priming pump vibration, replace new bearing can solve.

4, due to the self-priming pump pipe diameter is not in accordance with the standard caliber configuration of imports and exports, such as stainless steel exports self-priming pump inlet piping is 100 mm and 100 mm, but some users never consult manufacturer, directly change the inlet piping is small, cause into water little couldn't keep up with self-priming pump water yield, that is why the self-priming pump vibration is the cause of self-priming pump noise is not normal.

self-priming pump in use there will be a failure, if judgment, improper handling, will affect the performance of self-priming pump doesn't even work, longest appear the phenomenon of self-priming pump self-priming pump is not water, tell you the solution:

( 1) Check before starting the pump body of water storage chamber and enough water.

( 2) If there is a leak or blocking phenomenon suction pipe. If you have should be ruled out immediately.

( 3) Self-priming sewage water pump impeller mouth is closed. Such as jam to dredge.

( 5) If the water pump speed is too low, to the normal speed. Check whether the mechanical seal and framework oil seal is damaged. Such as damage to replace.

( 6) Backflow hole must be clear in the pump body, otherwise, the reflux hole cleaning, remove blockage.
