1.Horizontal multi-stage pump does not absorb water or water. The cause of this failure is mostly due to the end of valve stuck, part of the blockage of water, high water or water pipe leakage is too high. Should be checked one by one, taken at the end of valve repair, clear the blockage and correct the steering and other processing.
2.Pipeline leakage or leakage. No more than nuts tightened due. If the leakage is not serious, can be applied to cement slurry, mud or soft soap in the leakage; if the joints Water Leakage, tighten the nut wrench can be used. Serious leakage, leakage, must be re assembled.
3.Multi-stage centrifugal pump severe vibration. May be the motor rotor is not balanced or shaft coupling. Sometimes bearing wear, bending, rotating parts of the relaxation, rupture, pipeline stent is not strong also cause vibration. Should be adjusted, reinforcement, inspection or replacement.
4.The impeller is bad. When the damage is not large, can be repaired. Hard alloy should be replaced or plated when the damage is serious. Completely damaged, the impeller should be removed, the repair shop to repair.
5.Horizontal multi-stage pump shaft bending. Is due to the impact load, belt pulled too tight, causing incorrect installation. If the bend is not serious, can be used manually screw to correct, but not too hard, in case of a complete break.
