1. Maintenance of the fuel supply system: Ensure that the fuel supply system is accurately adjusted, follow the data in the manual, and accurately check and adjust the fuel supply advance angle. After 500 hours of operation, calibrate again to maintain efficient operation. Use light diesel oil that meets national standards, and clean the diesel tank and filter regularly to maintain the oil circuit unobstructed.
2. Oil monitoring and maintenance: Check the oil level of the governor every day and replenish it in time. For injection pumps and governors with skeleton oil seals, oil needs to be added separately. Abnormally high oil volume needs to be alert, which may be a serious oil leak and needs to be eliminated in time.
3. Regular maintenance: Replace the oil in the high-pressure oil pump and governor within the specified time, and clean the oil pump filter at the same time to ensure that the system is clean and unblocked.
4. Professional operation: Be cautious when disassembling and adjusting the injection pump, especially those sealed parts. Repairs by non-professionals may cause damage, so be sure to seek the help of professionals.
5. Storage and maintenance: If it is not used for a long time, make sure that the fuel injection pump oil channel is filled with diesel. After disassembly, it should be stored in a dry environment under the protection of anti-rust oil, away from acidic and alkaline items to prevent corrosion.
6. Check fasteners and seals: Regularly check whether the fasteners of the diesel water pump are loose, and tighten them in time. Check whether the seals such as oil seals and O-rings are damaged or aged, and replace them in time if necessary.
7. Check the bearings: Observe whether the bearings of the diesel water pump are worn or rusted, and lubricate or replace them if necessary. At the same time, check whether the bearing clearance meets the requirements.
8. Check the motor windings: Check whether the motor windings of the diesel water pump are short-circuited or open-circuited, and repair or replace them if necessary. At the same time, check whether the motor insulation resistance meets the requirements to ensure the safe operation of the motor.
9. Check the cooling system: Check whether the cooling system of the diesel water pump is working properly, such as whether the water tank, fan and other components are blocked or leaking. Clean or replace damaged parts if necessary.
Through the above maintenance measures, the efficient operation and extended service life of the diesel engine water pump can be ensured.
