Basic maintenance requirements
Cleaning and environmental maintenance
Keep the pump body and surrounding environment clean, dry, and free of oil stains to avoid leakage of media accumulation leading to corrosion or contamination of components.
Clean the sediment in the pump cavity and flow channel regularly, especially after long-term shutdown, rinse it before starting to prevent blockage.
Oil level and lubrication management
Components Maintenance points Reference cycle
Bearing box Check whether the oil level is near the middle scale line of the oil dipstick. If it is insufficient, add lubricating oil in time once a week
Lubricating oil replacement After continuous operation for 600-800 hours, completely replace the lubricating oil to ensure lubrication effect About 2-3 months
Packing lubrication The dynamic and static rings using lubricating grease need to be refueled regularly every day; the pressure and flow of the shaft seal water must meet the requirements, and water should be added in time when the temperature is too high12 Daily inspection
Maintenance points during operation
Real-time monitoring and abnormal handling
Vibration and sound: Ensure that there is no abnormal sound or severe vibration during operation. If any problem is found, stop the machine immediately for inspection.
Pressure and current: monitor outlet pressure (specific filler is required when ≤0.5MPa) and current stability to avoid overload operation
