I. Daily Use
1. Pre-startup inspection: Ensure there are no obstructions around the pipeline centrifugal pump and that the base mounting bolts are securely fastened. Check whether the bearing lubricant is sufficient and whether its quality meets the requirements. Verify that sealing fluid has been properly filled into the seal chamber, and ensure that the exterior of the sealing area is clean.
2. Startup Procedure: During startup, close the outlet valve, gradually increase the flow rate, and reduce the startup load. At the same time, pay close attention to changes in current, voltage, and power, ensuring they remain within the specified ranges.
3. Operational Monitoring: During operation, periodically check the pump’s vibration, noise level, bearing temperature, and other parameters to ensure they remain within normal ranges. At the same time, regularly inspect the inlet and outlet flow rates and pressure fluctuations to guarantee stable performance of the centrifugal pump.
II. Maintenance
1. Regular Inspections: Check the quality and liquid level of bearing lubricant weekly to ensure proper bearing lubrication. Monthly, inspect the condition of sealing areas; if any leaks or severe wear are detected, replace the seals promptly.
2. Quarterly Maintenance: Conduct a comprehensive inspection of the pipeline centrifugal pump once per quarter, including tightening screws and cleaning out impurities. At the same time, check the internal wear condition of the pump components, such as the impeller and pump casing; if necessary, carry out repairs or replacements.
3. Annual Overhaul: Conduct a comprehensive overhaul at least once a year, including replacing bearings, seals, and repairing worn components. At the same time, perform a thorough inspection and maintenance of the piping system to ensure that the pipelines remain unobstructed.
4. Idle Maintenance: If the pipeline centrifugal pump is to be left idle for an extended period, the inside of the pump should be cleaned and coated with rust-preventive oil, then stored in a dry, well-ventilated location.
In addition, the following points should also be noted: Avoid running the pump under no-load conditions and prolonged operation under overload; avoid frequent starts and sudden shutdowns; pay attention to the impact of ambient temperature on the pump; and keep the area around the pump clean. By adopting these daily usage and maintenance measures, you can effectively ensure the normal operation of the pipeline centrifugal pump, extend its service life, and reduce the likelihood of failures.
