What Should I Do If I Encounter These Faults When Disassembling And Assembling The Slurry Pump?

What should I do if I encounter these failures when disassembling and assembling the slurry pump?1) The disassembly and assembly of the pump head part of the slurry pump pump head part and the clearance adjustment of the pump head part should be carried out according to the assembly drawing.The impeller, sheath, rear guard plate and sealed box are all equipped with lifting tools for disassembly and assembly (lifting tools need to be ordered separately).For disassembly and assembly methods, please refer to the \"Suspension Tool Instructions\".2) The disassembly and assembly of the shaft filler shaft filler in the shaft seal part should be carried out according to the assembly drawing. In order to ensure the sealing effect of the shaft seal of the filler, the shape of the filler opening should be cut as much as possible as possible as shown in the figure below. When loading into the filler box, the openings of the adjacent filler should be staggered by 108 degrees.Slurry pump fault and treatment method: Fault Fault Series Solution Motor Overcurrent 1. The pump head is higher than the actual pipeline head.2. There is friction between the impeller and the guard plate.3. The power of the equipped motor is small.4. Bearings are damaged.5. The motor shaft and the pump shaft have different centers.1. Lower the pump head or close the pump outlet valve.2. Adjust the axial position of the impeller to overcome friction.3. Change the high-power motor.4. Replace new bearings.5. Adjust the concentricity of the two axes.The pump does not come on when the pump is started 1. The air in the pump is not removed.2. Air intake of the suction pipeline system.3. Air intake at the shaft seal.4. The suction pipe or impeller is blocked.1. Add exhaust measures.2. Exclude air intake reasons.3. Adjust the sealing performance to ensure the sealing volume and water pressure of the shaft sealing water.4. Eliminate blockage.Low pump lift 1. The pump lift is lower than the actual pipeline lift, resulting in a small pump flow.2. The pipeline cavitation allowance is less than the pump must be cavitation allowance, resulting in a small pump volume.3. The pump inlet valve is not expanded or the valve is damaged, causing the pump to be cavitated.4. Air intake of the suction pipeline system.5. The suction pipe or impeller is blocked.6. The slurry concentration is too high.1. Increase the pump head.2. Build a pipeline device so that the pipeline cavitation allowance is greater than the pump. The necessary cavitation allowance or replacement of the pump whose cavitation performance meets the requirements of the pipeline device.3. Expand the imported valve or replace the new valve.4. Exclude air intake reasons.5. Eliminate blockage.6. Reduce the slurry concentration or change to a pump with a larger size.Pump vibration and noise 1. The pump or pipeline is not installed firmly.2. The pump is carried out in a cavitation state.3. The pump motor has different concentrations.4. The impeller or coupling is not statically balanced and exceeds the difference 5. The coupling elastic pad is damaged.6. Bearings are damaged.7. Insufficient slurry supply causes pump evacuation.8. The characteristics of the pipe pump are not matched and the pump is caused by the pump cavitation.9. The suction pipe or impeller is blocked.10. Local air.11. There are many reasons for pump vibration and noise, and it needs to be solved specifically based on the actual situation on site.1. Reinforce and install firmly.2. Adjust the cavitation characteristics of the pipe pump so that the cavitation allowance of the pipeline is greater than the necessary cavitation allowance of the pump.3. Adjust the concentricity of the two axes 4. The impeller or coupling is regenerated and balanced to make it qualified.5. Replace the new elastic pad.6. Replace new bearings.7. Increase the amount of slurry or close the outlet valve of the pump.8. Adjust the pump characteristics to match the pipeline characteristics.9. Eliminate blockage.10. Add an exhaust valve to the air in the air in the air to remove the air in the air.Shaft seal leakage slurry 1. No shaft sealing water is added or the pressure of the shaft sealing water is too small.2. The filler is loose or installed incorrectly.3. The filler is broken.4. Severe wear of the shaft sleeve.5. The mechanical seal installation is unqualified.1. Increase the shaft sealing water or increase the shaft sealing water pressure.2. Adjust the filler loose to achieve sealing performance and install the filler according to 5-4 pieces.3. Replace new filler.4. Replace a new shaft sleeve.5. Reinstall the mechanical seal.Oil leakage from bearing components 1. Too much oil refueling.2. The bearing gland seal is not installed properly.3. Oil leakage at the oil standard.1. Recharge the fuel to the oil mark indicating position.2. Reinstall.3. Reinstall the oil mark.Bearing heat 1. Improper matching of the characteristics of the pipe pump, causing pump vibration, evacuation and cavitation.2. The motor shaft and the pump shaft have different centers.3. The elastic pad of the coupling is damaged.4. The oil is too dirty or the oil chamber is slurry.5. The bearing bead frame is worn or damaged.1. Adjust the characteristics of the pipe pump to make it reasonably match.2. Adjust the concentricity of the two axes.3. Replace the new elastic pad.4. Replace new oil to prevent slurry in the oil chamber.5. Replace new bearings in the cleaning oil chamber.
