What is the abnormal sound vibration of a self suction pump? Many people think this is because of the quality of self-priming pump, in fact, it is not, the main cause of self suction pump vibration is the following several points for reference:
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 fact that the concentricity of the coupling is not adjusted well or the wear of the rubber block in the coupling causes the phenomenon of large self absorption pump when installing the ZX self suction pump, it is necessary to recalibrate the concentricity of the coupling or replace the new rubber block and adjust the concentricity.
3, and may be self suction pump bearing damage is also the cause of self suction pump vibration, the replacement of new bearings can be solved.
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, the water level in the sump falls or the flow is too urgent, which leads to the abnormal sound of the self-priming pump when the suction pump is absorbed into the air.
Self priming pump will malfunction in use. If it is judged or handled improperly, it will affect the performance of self priming pump and even fail to work. The longest phenomenon of self priming pump is self suction pump without water, and tell you how to solve it.
[self priming pump does not come out of water]
(1) check whether the water storage chamber of the pump body is added enough water before starting (at least the water surface exceeds the vane center line). Otherwise, add water.
(2) whether the rotation direction is in accordance with the requirements. If it is not consistent, it can be adjusted to the same direction as the rotating direction of the pump.
(3) Self-priming sewage pump impeller inlet is blocked. If the blockage is to be dredged.
(4) whether there is leakage or blockage of the water suction pipe. If any, it should be ruled out immediately.
(5) check whether the mechanical seal and the skeleton oil seal are damaged. If the damage is to be replaced.
(6) the reflux hole in the body of the pump must be unblocked, otherwise, the reflux hole should be cleaned and the blockage is cleared.
(7) if the speed of the pump is too low, it should make it reach the normal speed.
