How does the car water pump work? Automotive water pump bearing manufacturers answer for you

    Centrifugal water pumps are widely used in car engines. Its basic structure is composed of water pump housing, connecting plate or pulley, water pump shaft and bearing or shaft bearing, water pump impeller and water seal equipment and other parts. The engine rolls through the belt pulley and the impeller of the water pump. The coolant in the water pump is rotated by the impeller and is thrown to the edge of the water pump housing under the action of centrifugal force. A certain pressure is generated together, and then flows out from the water outlet or water pipe. . The pressure at the base of the impeller drops because the cooling liquid is thrown out. The cooling liquid in the water tank is sucked into the impeller through the water pipe under the pressure difference between the inlet of the water pump and the base of the impeller, completing the reciprocating circulation of the cooling liquid.　 The bearing supporting the water pump shaft is smooth with smooth grease, so it is necessary to prevent the coolant from leaking to the smooth grease to form a smooth grease emulsification, and at the same time, to avoid the coolant from leaking. The sealing methods to avoid leakage of the water pump include water seals and gaskets. The water seal dynamic seal ring and the shaft are installed between the impeller and the bearing through interference cooperation, and the water seal static seal seat is tightly leaned on the housing of the water pump, and then achieves the intention of sealing the coolant.

    The main purpose of the car water pump bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its reversal accuracy. The purpose of the smoothness of rolling bearings is to reduce internal friction and wear of the bearing, avoid sticking; extend its service life; discharge frictional heat and cooling, avoid overheating of the bearing, and avoid aging of the lubricating oil itself; also prevent foreign matter from intruding into the bearing, or avoid rust and corrosion The role.
