Automobile water pump is the main part of the forced circulation of automobile cooling system. The engine drives the water pump bearing and impeller to rotate through the belt pulley. The coolant in the water pump is driven by the impeller to rotate together. Under the effect of centrifugal force, it is thrown to the edge of the water pump housing. At the same time, it generates a certain pressure and then flows out of the water outlet or water pipe.
The engine drives the water pump bearing and impeller to rotate through the belt pulley. The coolant in the water pump is driven by the impeller to rotate together. Under the effect of centrifugal force, it is thrown to the edge of the water pump housing. At the same time, it generates a certain pressure and then flows out of the water outlet or water pipe. The pressure at the center of the impeller is reduced due to the coolant being thrown out. The coolant 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 center of the impeller to realize the reciprocating circulation of the coolant.
The bearing supporting the water pump shaft is lubricated with grease, so it is necessary to prevent the coolant from leaking to the grease to cause the grease emulsion, and also prevent the grease from leaking. Sealing measures to prevent leakage of water pump include water seal and gasket. The dynamic seal ring and shaft of the water seal are installed between the impeller and the bearing through interference fit, and the static seal seat of the water seal is tightly pressed onto the housing of the water pump to seal the coolant.
The water pump housing is connected with the engine through a gasket and supports moving parts such as bearings. The water pump housing is also provided with a drain hole, which is located between the water seal and the bearing. Once the coolant leaks through the water seal, it can leak out from the drain hole to prevent the coolant from entering the bearing cavity and damaging the bearing lubrication and causing corrosion of components. If coolant leaks out after the engine is stopped, the water seal is damaged.
