Description

technical field

[0001] The invention relates to a water pump test stand, in particular to a water pump durability test stand. Background technique

[0002] The water pump is an important part in the cooling system of the automobile engine. Its function is to pump the coolant, so that the coolant can flow rapidly in the engine cooling water channel, take away the heat generated during the engine operation, and maintain the normal working temperature of the engine.

[0003] If the water pump fails, it will make the water temperature too high and may cause engine failure. In fact, in the engine failure, the failure caused by the high water temperature occupies a very high proportion, and the high water temperature is caused by the failure of the water pump. Generally speaking, the water pump of the engine has entered a period of high incidence of failure when it has been used for about 100,000 kilometers. In order to ensure the quality of maintenance, many water pumps are mai...
