In order to give full play to the bearing and maintain its due performance for a long time, regular maintenance (regular inspection) must be done. Through proper regular inspection, it is very important to find faults early and prevent accidents before they happen, which is very important to improve productivity and economy.
When removing the bearing for inspection, first make appearance records by photography and other methods. en outre, confirm the amount of remaining lubricant and sample the lubricant before cleaning the palier.
un. The cleaning of bearings is divided into rough cleaning and fine cleaning, and a metal grid can be placed at the bottom of the container.
b. During rough cleaning, use a brush to remove grease or adhesion in the oil. En ce moment, the bearing surface will be damaged due to foreign matters, such as rolling oil.
c. During fine cleaning, rotate the bearing slowly in oil and carry out it carefully.
The commonly used cleaning agent is neutral water-free diesel oil or kerosene, and sometimes warm lye is used as needed. No matter what kind of cleaning agent you use, always filter it and keep it clean.
In order to judge whether the removed bearing can be reused, it is necessary to check its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and sealing ring.
The judgment criteria vary according to mechanical properties, importance and inspection cycle. In case of the following damage, the bearing shall not be reused and must be replaced.

B. stripping of the rolling surface of the raceway surface.
Every bearing has a certain service life potential. Research has shown that, for various reasons, not every bearing achieves it. Important stages which have a major impact on a bearing service life can be recognised during the bearing’s lifecycle.Bearing Maintenance
These stages are mounting, lubrication, alignment, basic condition monitoring and dismounting. The stages in a bearing life cycle are extremely important for achieving the maximum service life of the bearing. By applying the right maintenance practices and using the correct tools, you can considerably extend your bearing’s service life and increase plant productivity and efficiency.Bearing Maintenance
If the bearing of the water pump is not good, it is one of the important parts of the bearing of the water pump. During the daily maintenance of water pump products, pay special attention to the maintenance of bearings. How to do the maintenance of water pump bearings? Let’s follow Xiaobian to have a look.
For the newly put into use water pump, under normal circumstances, it is necessary to replace the lubricating grease (oil) once after 100 hours of operation, and then it is enough to replace it once every 500 hours.
en outre, after 1500 hours of operation, the lubricating grease on the flow bearing should be replaced, and the amount of oil should be appropriate and added to the specified position, Otherwise, too much and too little will easily lead to bearing heating.
The container used to hold lubricating oil or grease should be kept clean and well sealed, and do not fall into dust and other sundries, otherwise it will cause certain damage to the bearing.
en outre, it should be noted that sodium based grease should not be used for the lubrication of water pump bearing, because this kind of grease has the characteristics of high temperature resistance (125 ℃) and is easy to dissolve in water, so, Sodium based grease is not suitable for the lubrication of water pump bearings.
