Multistage slurry pump failure Daquan, multi-stage slurry pump troubleshooting

Compared to other pumps, slurry pump operating environment is the most complex, therefore, the probability of failure has also increased a lot. The following is a small series compiled on the multi-stage slurry pump fault and solution Daquan, hoping to help you! Multi-stage slurry pump Daquan Daquan, multi-stage slurry pump troubleshooting solutions Causes of failure The pump can not start the protection circuit Work check protection circuit prime mover failure check, repair prime mover no water pump suction pipe full of water fill again suction, discharge valve closed dead open suction, discharge valve filter, suction tube blocked disassemble and remove foreign matter foreign matter in impeller disassembly Production of anti-foreign objects to reverse the direction of rotation to adjust the motor wiring can not reach the design flow Air suction Check suction pipe and sealing parts due to lower water levels, submerged depth is not enough to extend the suction pipe, deepen the depth of submerged foreign matter blockage Removal and removal of foreign matter Impeller wear serious replacement Impeller at the beginning of a drainage, but immediately stop pumping suction pipe insufficient irrigation again filled (according to the installation of siphon bucket condition) air suction check suction pipe and sealing parts suction pipe air accumulation reset pipeline overload rotation speed too Quickly adjust the prime mover 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 weight is too large to increase the motor power, change the impeller clearance grease bearing grease blockage, to the oil Insufficient replacement of lubricating oil Aging of oil Change of lubricating oil Bearing eccentricity, bearing side cover too tight Correction, replacement of spindle Adjusting side cover clearance Bearing defective Check, repair or replace Pump vibration Impeller partially blocked Remove and remove foreign matter Impeller Damaged removal and replacement of impeller flow is too small In the vicinity of the design point of the pump and the original motivation is not the same point Positioning bearing repair damage, check or replace the turbidity change suction water level, improve the suction pipe, design flow point work (Editor: Huang Nengwen QQ:)
