Shaft seal leakage is one of the common faults of slurry pumps, mainly caused by shaft seal wear, uneven sealing surface, or improper installation. The solution is to replace the worn shaft seals to ensure that the sealing surface is flat and smooth; Adjust the installation position of the shaft seal to ensure that the clearance between it and the shaft is appropriate; Check the clamping force of the shaft seal to ensure the sealing effect.
The impeller of the slurry pump is the core component of the slurry pump, and its wear directly affects the performance of the pump. The main cause of impeller wear is the erosion of solid particles in the medium. The treatment method is to regularly measure the wear of the impeller, and when the wear reaches a certain level, a new impeller should be replaced in a timely manner; For impellers with light wear, repair techniques such as welding and spraying can be used for repair.
During the maintenance process, the components should be cleaned, repaired, or replaced according to the maintenance plan, and then assembled.
1. Cleaning: Place the disassembled parts into a cleaning tank and use cleaning agents or high-pressure water guns to clean and remove surface dirt and oil stains. After cleaning, dry with a clean cloth or blow dry with compressed air.
2. Repair or replacement: Repair or replace worn, corroded, or damaged parts. The repair methods include welding, spraying, grinding, etc; For irreparable components, new ones should be replaced.
3. Assembly: Assemble in the reverse order of disassembly. During the assembly process, attention should be paid to parameters such as fitting clearance and tightening torque of each component to ensure assembly quality. At the same time, lubricate and seal vulnerable parts such as bearings and sealing rings.
