Structure and working principle of electronic water pump The water pump is an important component of the automotive engine cooling system, and its main function is to drive the circulation of the coolant, absorb excess heat from the engine, and transmit it to the external air through a heat dissipation device to avoid excessive engine temperature. High engine temperature can reduce the lubricating capacity of the engine oil, leading to increased wear of the components. High temperatures to a certain value can lead to serious faults such as engine cylinder pulling or tile burning, ultimately leading to engine burnout and scrapping. Water pumps are divided into traditional mechanical water pumps and electronic water pumps. The traditional engine generally uses a mechanical water pump, which is driven by a pulley to rotate the pump bearing and impeller. The coolant in the water pump is driven and rotated by the impeller, and is used to the edge of the water pump housing under…
