What are the reasons that cause the diesel engine water pump to fail to supply water?

Apr 27, 2024

When the diesel engine water pump is used for a long time, it will fail to supply water. What are the reasons that cause it to not supply water? Here are some of the reasons why.

 

When the water temperature in the diesel engine body rises, the thermostat will open to circulate the cooling water and the water in the radiator tank. The water outlet pipe on it is the channel for the high-temperature water in the body to flow to the radiator. If the water temperature in the pipe is low, it means that the cooling water inside and outside the engine is not flowing, and needs to be dealt with in time. Otherwise, the water temperature inside the engine will be too high, leading to a bigger cause of failure. In many cities, the water temperature is low for cooling the diesel engine water outlet pipe. The following is an analysis of common causes of failure.

1. The thermostat of the diesel engine water pump is broken. When the water temperature rises to the required temperature, the cooling water circulation valve cannot be opened, and the cooling circulation between the cooling water and the radiator tank inside the engine cannot be realized, which will cause the temperature of the upper outlet pipe to be too low.

2. The diesel engine cooling circulation water pump of the diesel engine water pump is damaged, resulting in the cooling water in the body being unable to circulate with the cooling water in the radiator, resulting in low temperatures in the upper part and the water outlet pipe.

3. If the cooling water pump of the diesel engine is belt-driven, and the belt is too loose or damaged, the engine cooling water pump circulation will be weak or not working, so that the internal and external circulating water cannot circulate for heat dissipation, and the temperature of the upper part and the outlet pipe will be low.

4. If this situation occurs after replacing the coolant of the diesel water pump engine, you should also consider whether there is air in the circulating water channel when replacing and adding coolant, resulting in large air resistance in the circulating water channel, poor heat dissipation of the internal and external circulating water, and upper outlet. Water pipe temperature is low.

5. If the engine is left for a long time or a special cooling solution is not added for a long time, the scale in the engine body will be too thick or too much, blocking the circulation of waterway, making the internal and external circulation waterways unblocked, and also causing the temperature of the upper outlet pipe to be low.

6. When working in a low-temperature environment, it is normal for the water pipe temperature to be low at first. Because the thermostatic valve is not open and the internal and external cooling water circulation has not yet occurred, the temperature of the upper water pipe will be lower during this period.

When using the diesel engine water pump, remember to observe it in time to find problems in time, instead of using it all the time without maintaining it.
