working principle
The engine drives the water pump bearing and impeller to rotate through the pulley. The cooling liquid in the water pump is driven by the impeller to rotate together, and is thrown to the edge of the water pump housing under the action of centrifugal force. At the same time, a certain pressure is generated and then flows out from the water outlet or water pipe. The pressure at the center of the impeller is reduced due to the cooling liquid being thrown out. The cooling liquid in the water tank is sucked into the impeller through the water pipe under the action of the pressure difference between the inlet of the water pump and the center of the impeller to realize the reciprocating circulation of the cooling liquid.
The bearings supporting the water pump shaft are lubricated with grease, so it is necessary to prevent the coolant from leaking into the grease to cause the grease to emulsify, and at the same time to prevent the leakage of the grease. The sealing measures of the water pump to prevent leakage include water seal and gasket. The water seal dynamic seal ring and the shaft are installed between the impeller and the bearing through an interference fit, and the water seal static seal seat is tightly press-fitted on the housing of the water pump to achieve the purpose of sealing the coolant.
The water pump housing is connected to the engine through a gasket and supports moving parts such as bearings. There is also a drain hole on the water pump housing, located between the water seal and the bearing. Once the coolant leaks through the water seal, it can be drained from the drain hole to prevent the coolant from entering the bearing cavity to damage the bearing lubrication and cause the parts to rust. If the coolant still leaks after the engine is stopped, it indicates that the water seal has been damaged.
