Common pump failure and troubleshooting: 1, the pump vibrates violently The reason is that the electric rotor is unbalanced or the coupling is not good, the bearing is worn and bent, the parts of the rotating part are loose and broken, the pipe support is not firm and so on. Can be taken to adjust, repair, reinforcement, straightening, replacement and other methods. 2, pipe leakage or leakage may be due to screw the screw cap is not tight. If the leakage is not serious, in the place of leakage or leakage coated with cement, mud or soft soap and so on. If the joint leaks, you can tighten the screw cap by hand. Leak serious must re-disassembly. Imported pump valve 3, poor pumping: filling overheating and more due to too tight packing pressure, cooling water into the filler or damage caused by the shaft surface. Proper relaxation of packing can be taken to clear up the sealing tube blockage and other measures. Filler wear must be replaced by new, before installation must be soaked in oil, ring by ring into. Cut to be staggered, so as to reduce leakage. After the last lap packing installed tightly gland, then adjust the tightness when running. 4, the pump is not water or not drained The reason for the end of the valve stuck more than the part of the drainage blockage, water absorption is too high or water leakage, but also may be due to the wrong, impeller runner blockage caused. After one by one inspection, respectively, to take the end valve repair, remove the blockage, to correct steering, impeller cleaning and other measures for processing. More Search Keywords: water pump
