Single-stage slurry pump fault Daquan, single-stage slurry pump troubleshooting

Based on the complex work environment of the single-stage slurry pump, a variety of faults may be encountered during use. As a qualified operator, we must be clear single-stage slurry pump all the possible causes of failure, and solutions to the chest, so as to be able to work more efficiently. Single-stage slurry pump failure Daquan, single-stage slurry pump troubleshooting solutions Causes of failure Measures can not start the pump Protection loop work Check the protection circuit The prime mover failure check, repair The prime mover does not pump The suction pipe water is less than full Fill inhalation, Exhaust valve closed Open suction, discharge valve Filter, suction tube blocked Disassemble and remove foreign matter Foreign matter in impeller Disassembly Remove foreign material Rotation Direction Inverted Adjust motor wiring Not up to design flow Air suction Inspect suction pipe and seal as level drops , Submerged depth is not enough to extend the suction pipe to deepen the depth of submergence foreign matter blockage in the impeller Removal and removal of foreign matter Impeller wear serious Replacement of the impeller at the beginning of drainage, but immediately stop pumping suction pipe insufficient irrigation again fill (according to loading siphon bucket conditions apply ) Air Inhalation Inspect Suction Tube and Sealing Area Suction Tube Air Cumulation Reset Pipeline Excessive Rotation Speed Too High Adjust the prime mover so that it reaches the specified number of revolutions Adjust the opening of the outlet valve beyond the design flow and design lift, Adjust the impeller back Body contact with the pump body, the material is too large Increase the motor power, adjust the gap for the impeller to adjust the gap Grease grease blockage, lack of oil Change the lubricant Oil aging Replace the bearing oil bearing eccentric bearing pressure too tight , Replace the spindle Adjust the side cover clearance Bearing faulty check, repair or replacement Pump vibration Impeller partial blockage Removal and removal of foreign matter Impeller damage Disassembly and replacement Impeller flow is too small In the vicinity of the design point The pump is not the same as the original motive pump Positioning Bearings bearing damage Repair, check or change the turbidity change suction water level, improve the suction pipe, design point flow work
