The cleaning of automobile water pump bearings is divided into rough washing and fine washing

The correct method of automobile water pump bearing:

1. In the process of using imported water pump bearings, regular cleaning is very important. How to properly clean imported water pump bearings? When the imported water pump bearing is removed for inspection, the appearance record should be recorded by photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the water pump bearings.

2. The cleaning of the water pump bearing is divided into rough washing and fine washing, and a metal grid can be placed at the bottom of the container in use.

3. For rough washing, use a brush to remove grease or adhesions in oil. At this time, if the water pump bearing is rotated in oil, be careful that the rolling surface may be damaged due to foreign matter.

4. When fine washing, slowly rotate the water pump bearing in oil, and it must be done carefully.

5. The commonly used cleaning agent is neutral non-water-containing diesel or kerosene, and sometimes warm lye etc. are used as needed. No matter what kind of cleaning agent is used, it must be filtered frequently to keep it clean.

6. After cleaning, immediately apply anti-rust oil or anti-rust grease on the imported water pump bearings.

The water pump shaft is connected to the bearing, because it is composed of a main shaft and a ring, which is equivalent to a combination of two zero-class bearings.

The water pump is composed of a water pump housing, shaft bearing, water seal, impeller, fan and transmission parts. Automobile water pump shaft bearing is an important part of water pump. Due to the high speed of the water pump, the general water pump speed reaches 6000r/min, and the high speed water pump speed is as high as 9000r/min. Therefore, the shaft bearing is required to have a higher load-bearing capacity, so as to meet the requirements of the pump life under 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 automobile shaft bearing should be able to meet the requirements of maintaining normal operation at high temperatures without reducing the bearing capacity. The sealing of the bearing is difficult, and its sealing is reliable. Both performance and durability will directly affect the usability of the pump. In short, the bearing capacity, working clearance and sealing performance of the shaft bearing are three important performance indicators that affect the performance of the pump.

Automotive water pump bearings are a new type of structural bearing developed to meet the above needs. It is essentially a double-supported shaft system with a simplified structure. The two supported bearings do not have inner rings. The raceways of the rolling elements are directly made on the shaft. The two supported bearing outer rings are made into a whole. The two sides are sealed with seals to form the assembly of the shaft sleeve. Under the same bearing capacity, its radial dimension is smaller than that of a general type bearing; under the same radial size condition, its bearing capacity is greater than that of a general type bearing.
