Submersible Slurry Pump Maintenance Guide
  1. Regular Inspection and Maintenance

 

  1. External Inspection: Conduct a meticulous weekly examination of the pump's exterior, focusing on cable connections, casing integrity, and the cooling system. Ensure there is no corrosion, damage, or blockages.

 

  1. Internal Cleansing: Perform monthly internal cleansing. Disassemble pump components, including impellers, pump casings, and inlet/outlet paths, clearing away slurry, particles, and corrosive substances to maintain the pump's cleanliness and smooth operation.

 

  1. Lubrication and Protection

 

  1. Bearing Maintenance: Quarterly inspections and lubrication of bearings. Use high-quality lubricating grease to ensure smooth bearing operation and suitable temperatures. Regularly clean and replace bearing lubricants.

 

  1. Sealing Maintenance: Monthly checks on the pump's sealing system. Ensure intact sealing rings to prevent internal leaks and contamination.

 

  1. Electrical System Maintenance

 

  1. Motor Inspection: Comprehensive quarterly checks on motors, including current and voltage tests, insulation testing, and verification of motor's high-temperature protection features. Repair or replace any damaged electrical components.

 

  1. Insulation Testing: Bi-annual insulation tests to ensure the electrical system maintains a safe insulation state, minimizing potential electrical faults.

 

  1. Performance Monitoring and Adjustment

 

  1. Performance Monitoring: Monthly monitoring of pump operating parameters such as flow rate, head, and efficiency. Regularly record pump performance data, compare it with previous records, and make timely adjustments to maintain optimal performance.

 

  1. Shaft Power Testing: Quarterly measurement and analysis of pump shaft power. Changes in shaft power may indicate the pump's operating status or performance issues.

 

  1. Preventive Maintenance

 

  1. Maintenance Plan Development: Develop a detailed preventive maintenance plan outlining inspection cycles, maintenance procedures, and required resources. Strictly adhere to this plan to ensure the pump's long-term stable operation.

 

  1. Recording and Documentation: Document specific details, materials used, and time spent during each maintenance session. Establish comprehensive maintenance records to serve as references for future maintenance tasks.

 

Conclusion

The effective operation of submersible slurry pumps relies on regular maintenance and care. The provided guidelines offer detailed and specific maintenance steps and frequencies to ensure the reliability and stability of pump equipment. It is imperative to strictly follow the manufacturer's provided operation manuals and recommendations to ensure the safety and compliance of the maintenance process.
