Water Pump Bearings

The water pump is composed of a water pump shell, a water pump bearing, a water seal, an impeller, a fan and the transmission parts. Automobile water pump bearing is an important part of water pump. Due to the high speed of the water pump, the speed of the general water pump is up to 6000r/min, and the speed of the high-speed water pump is up to 9000r / min. Therefore, it is required that the water pump bearing has a high bearing capacity, so as to meet the life requirements of the water pump at a certain speed. The space position of the water pump is limited, the heat dissipation area is small, and the working conditions are poor. Therefore, the water pump bearing should meet the requirements of maintaining normal operation under high temperature and without reducing the bearing capacity. The sealing of bearing is difficult, and its sealing reliability and durability will directly affect the serviceability of water pump. In short, the bearing capacity, working clearance and sealing performance of the water pump bearing are three important performance indicators that affect the service performance of the pump.

With the development of automobile in the direction of high speed, high reliability and low energy consumption, it is required that the cooling water pump is developed in the direction of light weight, small volume, large flow and high speed. The water pump bearing is a new type of bearing with large bearing capacity, good rigidity, high rotation accuracy, long service life, reasonable structure and reliable operation. At present, it is not only widely used in automobile cooling water pump, but also widely used in textile machinery, engineering machinery and so on.
