1. Clean appearance:
Periodically clean the exterior of the diesel water pump unit, including the unit cavity, radiator, pump and diesel engine parts.
Use water and neutral cleaners to gently wipe, avoiding corrosive or organic solvents.

2. Check the lubrication system:
Regularly check whether the oil in the lubrication system is sufficient and replace or replenish the lubricant in time.
Pay attention to cleaning the filter of the lubrication system to prevent the clogging of the filter from affecting the lubrication effect.

3. Check the cooling system:
Check whether the coolant of the cooling system is sufficient, and clean the bolts and fixing nuts of the cooling fan and radiator.
If any abnormality is found in the coolant, it should be dealt with promptly.

4. Check the battery:
Regularly check the battery voltage of the diesel water pump unit and keep it in good charging condition.
If necessary, clean the connectors and terminals of the battery to ensure a good electrical connection.

5. Test unit operation:
Regularly test the operation of the diesel water pumping unit, including starting, running and stopping.
Observe any abnormalities in operation and make timely adjustments or repairs.

6. Maintain and check the oil supply system:
Use good diesel fuel and filters to ensure that the diesel fuel entering the injection pump is highly clean. Select the diesel fuel that meets the requirements of the grade, at least after 48h precipitation.

7. Check the sealing condition of the oil outlet valve:
After the injection pump has been working for some time, the sealing condition of the oil outlet valve can be checked to make a rough judgment on the wear of the plunger and the working condition of the oil pump.

8. Avoid arbitrary disassembly and adjustment:
The injection pump should not be disassembled and adjusted arbitrarily, and should be disassembled and maintained in a clean place.
