The car water pump is a centrifugal pump that is mainly used to circulate coolant to keep the engine’s temperature stable and normal operation. The working principle of a car water pump is as follows:
Automobile water pumps are composed of casing, impeller, bearings, seals, etc.
The car water pump is driven by the engine’s belt, causing the impeller to rotate at high speed, sucking the coolant from the water tank, and then forcing it into the engine cooling system.
When the impeller rotates, due to the centrifugal force, the liquid flows out of the impeller and flows back to the water tank along the pump body.
At the same time, the sealing device of the automobile water pump prevents coolant leakage.
When the engine is running at high speed, the speed of the car’s water pump will also increase to ensure the flow and speed of the coolant.
In short, the automobile water pump is an important part of the engine circulation cooling system. Through the centrifugal force generated by the high-speed rotation of the impeller, the coolant is drawn from the water tank and then pressed into the engine cooling system to maintain the constant required for normal engine operation. temperature.
