The oil pump of the oil filter is one of its core components, responsible for sucking and delivering the oil into the filtration system. To ensure the efficient operation of the oil filter and extend the service life of the oil pump, regular maintenance and care are essential. The following are the maintenance methods for the oil filter pump:
- Oil pump operation status:
- Check whether the oil pump runs smoothly and whether there is any abnormal noise or vibration.
- Observe whether the flow and pressure of the oil pump are normal.
- Seal inspection:
- Check whether the seals of the oil pump (such as shaft seals, and O-rings) are leaking.
- Oil cleanliness:
- Ensure that the oil entering the oil pump is clean to avoid impurities entering the pump and causing wear.
- Cleaning the inside of the oil pump:
- Disassemble the oil pump regularly, clean the pump cavity, impeller and inlet and outlet pipes, and remove deposited sludge and impurities.
- Cleaning filter:
- Clean or ｒｅｐｌａｃｅ the filter at the oil pump inlet to prevent impurities from entering the oil pump.
- Bearing lubrication:
- Regularly check and replenish the lubricating oil of the oil pump bearing to ensure smooth operation of the bearing.
- Seal lubrication:
- Lubricate the mechanical seal to prevent dry friction from causing seal failure.
- Impeller and pump casing:
- Check whether the impeller and pump casing are worn or corroded, and repair or ｒｅｐｌａｃｅ them if necessary.
- Shaft and sleeve:
- Check the wear of the pump shaft and sleeve to ensure that their concentricity and fit clearance meet the requirements.
- Seal:
- Check the wear of the mechanical seal or packing seal, and ｒｅｐｌａｃｅ the damaged seal in time.
- Bolts and fasteners:
- Check whether the connection bolts of the oil pump components are loose and tighten them if necessary.
- Pipeline connection:
- Check whether the connection of the inlet and outlet pipes is firm to avoid oil leakage or air intake.
- Pressure and flow:
- Regularly monitor the operating pressure and flow of the oil pump to ensure that it works within the design range.
- Temperature:
- Check the operating temperature of the oil pump to avoid overheating and damage to components.
- Develop a maintenance plan:
- Develop a regular maintenance plan (such as monthly, quarterly or annually) based on the frequency of equipment use and working environment.
- Spare parts reserve:
- Reserve commonly used wearing parts (such as seals, bearings, impellers, etc.) for timely replacement.
- Oil pump does not discharge oil:
- Check whether the oil pump is taking in air, clean the inlet filter, and ensure that the oil is sufficient.
- Insufficient flow:
- Check whether the impeller is worn, whether the pipeline is blocked and whether the oil viscosity is too high.
- Abnormal noise:
- Check whether the bearing is damaged, whether the impeller is loose and whether there is foreign matter in the pump.
- Leakage:
- Check whether the seal is damaged and whether the fastener is loose.
- Long-term shutdown:
- If the oil filter is shut down for a long time, it is necessary to drain the oil in the oil pump and pipeline, clean the oil pump and apply anti-rust oil.
- Reactivate:
- Before reactivating, check the status of each component of the oil pump to ensure that there is no rust or damage.
Through the above maintenance methods, the service life of the oil filter pump can be effectively extended, the efficient and stable operation of the oil filter can be ensured, and the failure rate and maintenance cost can be reduced at the same time. Regular maintenance not only improves equipment reliability but also ensures the quality of oil treatment.
