The function and working principle of the Engine water pump
The role of the automobile engine water pump is to drive the coolant to dissipate heat from the engine, to ensure that it circulates in the cooling system, to allow the water to circulate through the radiator continuously, to take away heat, and to ensure that the engine is not overheated. The engine drives the water pump bearing and the impeller to rotate through the pulley. The coolant in the water pump is driven by the impeller to rotate together, and is thrown to the edge of the water pump shell under the action of centrifugal force. At the same time, a certain pressure is generated, and then flows out from the water outlet or water pipe.

In the cylinder block of the car engine, there are many water channels for cooling water circulation, which are connected with the radiator placed in the front of the car through water pipes to form a large water circulation system. A water pump is installed at the upper water outlet of the engine. Driven by the fan belt, the hot water in the water channel of the engine cylinder is pumped out and the cold water is pumped in. There is also a thermostat next to the water pump. When the car is just started, it is not opened, so that the cooling water does not pass through the water tank, but only circulates in the engine. When the temperature of the engine reaches above 95 degrees, it is opened, and the hot water in the engine It is pumped into the water tank, and the cold wind blows through the water tank when the car is moving forward, taking away the heat.
