Fault causes and measures Pump can not start Protection circuit work Check the protection circuit The prime mover failure Check and repair the prime mover No water Pump suction pipe water is not full Re-fill with suction, discharge valve closed Death inhalation, discharge valve filter, suction pipe plug Disassembly And remove foreign matter Impeller with foreign matter Removal of foreign objects to remove the direction of rotation Anti-adjust the motor wiring up to less than the design flow Air suction Check the suction pipe and sealing parts As the water level lower, the submerged depth is not enough to extend the suction pipe to deepen the depth of submerged foreign impeller plug Removal and removal of foreign matter Impeller wear serious Replacement of the impeller at the beginning of a drainage, but immediately stop the pump suction pipe insufficient irrigation again fill (according to siphon bucket conditions apply) air suction check the suction pipe and sealing parts suction pipe air accumulation re- Set the pipeline overload rotation speed too fast adjust the prime mover so that it reaches the specified number of revolutions in the design flow, the design lift operation to adjust the opening of the outlet valve to adjust the impeller rotary body contact with the pump body, the material is too large increase motor power , Change the impeller clearance gap bearing heat grease Clogged, insufficient oil Replacement of oil Lube oil aging Replace oil bearing eccentric, bearing side cover too tight Re-find, replace the spindle Adjust the side cover clearance Bearing faulty check, repair or replacement Pump vibration Impeller partial blockage Disassembly And remove the foreign body impeller damage Remove and replace the impeller flow is too small in the vicinity of the design point of the pump and the prime mover is not the same point to find bearing damage repair, inspection or replacement of turbidity change suction water level, improve the suction pipe, design point flow work
