Electronic water pump structure and working principle The water pump is an important component of the automobile engine cooling system. Its main function is to drive the coolant circulation, absorb excess heat from the engine and transmit it to the outside air through the heat sink to avoid excessive engine temperature. If the engine temperature is too high, the lubriing ability of the engine oil will decrease, which will lead to aggravated wear of the parts. If the temperature reaches a certain value, it will cause serious failures such as engine cylinder scuffing or burning of tiles, and eventually the engine will be burned and scrapped. There are two types of water pumps: traditional mechanical water pumps and electronic water pumps.
