Analysis Of The Causes Of Bearing Damage Such As Centrifugal Pumps And Submersible Pumps

Centrifugal pumps, submersible pumps, multistage pumps and other rolling bearings in the use of their own quality and external conditions, their bearing capacity, rotation accuracy and anti-friction performance will change, when the performance index of the bearing is lower than the use requirements and can not work normally, it is called bearing damage or failure, once the bearing is damaged and other accidents, there will be its machine, equipment stop, function damage and other abnormal phenomena.

Therefore, it is necessary to investigate and deal with the causes of occurrence in a short period of time, and take corresponding measures, of course, the situation of rolling bearing damage is much more complicated than the damage of general mechanical parts, rolling bearing damage is characterized by many manifestations, complex reasons, bearing damage in addition to the internal factors of bearing design and manufacturing, most of them are due to improper use, such as: selection cloth suitable (see customer notice), unreasonable support design, improper installation, poor lubrication, poor sealing and other external factors.

It is of great significance to study the formation and causes of rolling bearing damage, on the one hand, we can improve the use method, use the bearing correctly, give full play to the due efficiency of the bearing, and on the other hand, it will help to develop new products with better performance. In addition to describing the precautions in the use of rolling bearings, installation methods, operation monitoring, etc., this article also focuses on the forms and causes of bearing damage and the countermeasures that should be taken.
