Analysis of the reason:
1. Because self suction pump equipment installation is not accurate, some users to saving energy directly to the self-priming non clogging sewage pump random factory fixed self-priming pump wood bracket together with self-priming pump together on the ground is connected to the inlet and outlet pipe directly use, as well as the user is the self-priming pump is fixed and welded in the iron triangle bracket, because the trivets too is not a single solid as long as a few self-priming pump base and the triangle touch this approach is not accurate, the correct way is remove the wood put pump are fixed on the solid flat on the ground.
2. Because in the installation of ZX self priming pump coupling concentric degree unadjusted perhaps good coupling to the inside of the rubber block wear resulting in self-priming pump oscillation phenomenon appears, when should de novo school couplet coupling concentricity may replace the new rubber block and adjust the concentricity.
3. There may be a pump bearing damage to the factors will also be a large self suction pump oscillation factors, the replacement of the new bearings can be processed.
4. Because self-priming pump import and export diameter not in accordance with the norms of the caliber of the equipment, such as stainless steel self-priming pump inlet pipeline is 100mm export is 100mm, and some users without consulting the manufacturers directly to the inlet pipe of small change, resulting in water quantity is small and not self-priming pump water, this is self-priming pump oscillation factor is the self suction pump sound is not normal factors.
5. Ceiling inside the pool water level fell by perhaps the factors of flow too quickly, resulting in self suction pump suction belt into the air let self suction pump sound is not normal sight.
