water pump

The engine drives the pump bearing and impeller through the belt pulley. 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 shell, and a certain amount of pressure is generated, and then flowing out of the outlet or pipe. The pressure in the center of the impeller is reduced due to the throwing of the coolant. The coolant in the tank is sucked into the impeller through the water pipe under the difference between the inlet of the pump and the center of the impeller to realize the reciprocating circulation of the coolant.
