Analysis of the large sound vibration in the self priming pump

What self priming pump will be the sound vibration of the abnormal situation? Many people think this is because of the quality of the self priming pump, in fact, because of the big reason for the vibration of the pump, the main reason is as follows:
1, the self suction pump installation is not correct, some users of self suction non clogging sewage pump random factory fixed self-priming pump self-priming pump bracket with the wood together on the ground with the import and export pipeline is directly used to directly in order to save time and effort, and the user is the self suction pump is fixed on the triangle welding the bracket, because too single trevet isn't solid. Only a small amount of self suction pump base and the triangle with this method is not correct, the correct way is to remove the wooden pump fixed on a hard flat surface.
2, due to the installation of ZX coupling self-priming pump when the concentricity is not adjusted or coupling inside the rubber block wear leads to self suction pump vibration phenomenon, it should be re concentric coupling degree of correction or replacement of new rubber block and adjust the concentricity.
3, there may be a pump bearing damage caused by the pump will be a big reason for vibration, the replacement of the new bearings will be able to solve.
4, the self suction pump import and export is not in accordance with the standard diameter aperture configuration, such as stainless steel self-priming pump inlet pipe is 100mm export is 100mm, some users without consulting the manufacturers directly to the import pipeline, resulting in small water quantity to keep up with the self suction pump out of water, which is the self suction pump vibration the reason is the self suction pump sound is not normal.
5, suction pool water level drops or water too fast, resulting in self-priming pump water into the air to pump sound is not a normal phenomenon.
Self suction pump in use will fail, if judged, handled properly, will affect the working performance of self-priming pump self-priming pump can not even work, the phenomenon is the self suction pump water, to tell you the solution:
Self priming pump does not water
(1) check whether the pump body of the water storage room to start before the foot of the water (at least on the surface of the impeller more than the center line). Otherwise, to add enough water.
(2) whether the rotation direction is in compliance with the requirements. If not consistent, can be adjusted to the direction of rotation of the pump with the pump.
(3) Self-priming sewage pump impeller inlet is blocked. If the blockage to clear.
(4) whether there is leakage or blockage of water absorption. If there is, should be immediately ruled out.
(5) check the mechanical seal and the skeleton oil seal is damaged. If the damage is to be replaced.
(6) in the body of the pump flow must be clear, otherwise, to clean the reflux hole, clear the blockage.
(7) if the pump speed is too low, it should make it reach the normal speed.
