Diesel engine water pumps may not be used frequently for many people, so the maintenance of diesel engine water pumps is very important at ordinary times. So, let's take a look at the maintenance of the diesel engine water pump.

1. Check the oil level of the oil pan. Check whether the oil level is displayed on the oil gauge. If it is insufficient, add it to the specified amount, but it should not exceed the upper limit of the oil gauge. The diesel fuel supply specification is: replace every 12 months, and replace the diesel filter every 12 months.

2. Check whether the grease in the oil filling point is sufficient. Remove the grease nipple of the diesel engine circulating pump and observe whether the grease inside is sufficient. When insufficient, use a grease gun to add enough grease, if necessary, once a week.

3. Check whether the water in the cooling water tank of the diesel engine water pump is sufficient. When the water in the tank is not enough, it should be replenished immediately. The water you put in should be clean fresh water. Directly adding groundwater will form scale in the water tank, which will easily affect the cooling effect and cause failure. When the ambient temperature is below zero in winter, antifreeze with a suitable freezing point should be configured according to the low ambient temperature; the antifreeze should be replaced every 12 months (50-32 ethylene glycol antifreeze), and the antifreeze should be replaced in November every year.

4. Check whether the oil in the oil tank of the diesel engine water pump is sufficient. The diesel oil in the oil storage tank is always sufficient, and shall not be less than 50% of the volume of the oil tank. When refueling, it is necessary to effectively remove moisture and impurities. Diesel oil is put in, and the diesel filter element is replaced every 12 months.

5. Daily inspection 3. Water leakage, oil and gas conditions. Check the sealing surface of diesel engine pump pipes and pipe joints. If any leakage is found, it should be solved in time. For example, if the exhaust pipe or the supercharger sealed in the cylinder is loose or leaks, it should be solved immediately.

6. When checking the diesel engine water pump battery: observe whether the box has cracks, bumps, and whether the positive and negative terminals are loose or slippery. When using a wet battery, it is necessary to observe the liquid level of the decomposition solution in the battery, making it 10~15mm higher than the surface of the plate.

7. Inspection after long-term operation: check the muffler and exhaust pipe of the diesel engine, remove carbon deposits to prevent sparks, and check the wear of the pump packing seal and replace it in time if necessary.

8. Check the installation of the accessories of the diesel engine water pump: the installation stability of the accessories, and whether the connection between the anchor bolts and the machine tool is firm.

9. Check the diesel engine water pump drive coupling: check whether the connecting bolts are loose, and if they are loose, tighten the bolts as soon as possible.

10. Clean the appearance of auxiliary equipment. Wipe the oil, water and dust on the surface of the main engine, cylinder head, air filter, etc. with a dry cloth or dipped diesel cloth, and use compressed air or a blower to blow off the dust on the surface of the generator, radiator, and fan.
