ChineseDuring the operation of the automobile water pump, there will be abnormal conditions and pre-rotation failure. How to deal with this situation and check it in time? The working condition of the automobile water pump is abnormal or the impeller of the automobile water pump is slipping, so that the pumping volume of the automobile water pump cannot be proportional to the engine speed, or the water seal is leaking.
Check the working status of the car water pump. Open the radiator water filler cap to make the engine slowly accelerate; observe the circulation of the cooling water in the water filler; if it continues to accelerate and the impeller does not slip, the car water pump is not working properly. On the contrary, there is a problem with the car water pump. When observing the circulation of the cooling water from the water inlet, another method can be used: turn off the engine when the water temperature is high, and quickly remove the hose from the car cylinder head to the radiator upper water chamber joint, and use a cloth ball to connect the upper water chamber If the connector is plugged, add cooling water to the radiator from the water filling port, and then start the engine. If the water in the cylinder water jacket and the radiator is pumped by the car water pump out of the hose, the impeller will not slip, indicating that the car water pump is working. Normal; otherwise, abnormal.
Automobile water pump flow test The automobile water pump flow test must be carried out on a special test bench. The driving device of the test bench drives the rotation of the automobile water pump to observe whether the displacement meets the manufacturer's standard or whether there is water leakage.
