What Are The Types Of Car Water Pumps?
(1) Electric water pump The electric water pump is controlled by the engine control unit through current, it is not affected by the engine speed at that time, and can work flexibly according to the actual cooling needs of the engine. Since the engine power consumed by the electric water pump is very small, the fuel consumption of the engine can be reduced by using the electric water pump.
(2) Mechanical water pump The mechanical water pump is driven by the crankshaft of the engine through the transmission belt, and its speed is proportional to the speed of the engine. There are advantages and disadvantages to the way a mechanical water pump works. When the engine works under high-speed and high-load conditions, the engine generates a lot of heat, and the high speed of the water pump increases the circulating flow of the coolant, which can just improve the cooling capacity of the engine; when the engine works under low-speed and high-load conditions At this time, for example, towing other vehicles or turning on the air conditioner, the low speed of the engine causes the speed of the water pump to be low, which reduces the cooling capacity of the engine.
