IV. Key Points for Maintenance of Vertical Centrifugal Water Pump
1. Daily Operation Inspection
- Status Monitoring: Observe and listen to the operation of the Vertical centrifugal water pump, checking for abnormal vibrations or noise.
- Parameter Check: Monitor whether the motor current is within the rated range, and observe if the readings of the outlet pressure gauge and vacuum gauge are stable and normal.
- Leak Inspection: Check the pump body, mechanical seal, or packing seal of the Vertical centrifugal water pump for any leaks. For packing seals, the normal leakage amount should typically be controlled at 10 to 20 drops per minute.
- Temperature Check: Check the bearing housing temperature of the Vertical centrifugal water pump, which generally should not exceed 40°C above the ambient temperature, and high temperatures usually should not exceed 75°C.
- Lubrication Check: Check whether the bearing oil level is within the specified range and whether the oil quality is clean.
2. Regular Maintenance of Vertical Centrifugal Water Pump
- Regular Lubrication: Every 500 hours of operation, replenish or replace the lubricating oil (grease) for the pump bearings to ensure smooth oil flow and oil quality compliance.
- Performance Check: Regularly verify whether the actual flow and head of the Vertical centrifugal water pump match the design conditions to avoid long-term operation under cavitation, over-flow, or over-current conditions.
- Fastening and Cleaning: Regularly check and tighten the base bolts and pipeline connectors of the Vertical centrifugal water pump to ensure there is no loosening. Keep the pump body and surrounding environment clean and dry.
- Alignment Check: For Vertical centrifugal water pumps connected by a coupling, regularly check and correct the concentricity between the pump shaft and the motor shaft.
- Long-term Storage Maintenance: If the Vertical centrifugal water pump is not used for a long time, drain the residual liquid inside the pump, apply anti-rust treatment to rust-prone parts, and manually rotate the pump shaft several times periodically to prevent parts from seizing or deforming.
3. Planned Overhaul and Key Component Inspection
- Comprehensive Disassembly and Inspection: Check the impeller, seal ring, pump shaft, and other key components of the Vertical centrifugal water pump for wear, corrosion, or cavitation, and replace them if necessary.
- Bearing and Seal Replacement: Check the bearing clearance and wear of the Vertical centrifugal water pump, evaluate the wear condition of the mechanical seal or packing seal, and replace as needed.
- System Calibration: Calibrate related monitoring instruments of the Vertical centrifugal water pump, such as pressure gauges and thermometers, to ensure accurate and reliable data.
