What is the function of the engine power water pump
Aug 16,2022
The function of the engine water pump is to drive the coolant to dissipate the heat of the engine, ensure that it circulates in the cooling system, keep the water circulating in the radiator, take away heat, and ensure that the engine is not too hot.
There are many water channels for cooling water circulation in the cylinder of the car engine. These water channels are connected with the radiator placed in the front of the car through water pipes to form a large water circulation system. The water pump is installed on the upper water outlet of the engine, driven by the fan belt, to pump out the hot water in the water channel of the engine cylinder, and pump the cold water in. There is also a thermostat next to the water pump. When the car is just started, it is not turned on, so the cooling water will only circulate in the engine and will not pass through the water tank. When the engine temperature reaches above 95 degrees, it will turn on, the hot water in the engine will be pumped into the water tank, and the cold air in the car will blow through the water tank to take away the heat.
The working principle of the pump is that the engine drives the bearing and the impeller of the pump to rotate through the pulley, and the coolant in the pump is driven by the impeller to rotate together. Under the action of centrifugal force, it is thrown to the edge of the pump casing, and a certain pressure is generated at the same time, and then flows out from the water outlet or water pipe.
