To improve the life of the motor, the first thing to do is to solve the bearing system problem. The necessary condition for the normal operation of the bearing system is that the bearing is well lubricated. In order to optimize bearing lubrication, grease is critical. Below, Dalan Motor Xiaobian will talk to you about how to choose the grease that is suitable for the special pump motor of the vane pump.
Select bearing grease for different considerations:
(1) Bearing grease must have anti-rust effect and good adhesion. The rust inhibitor in the grease is preferably insoluble in water, and the grease may adhere to the surface of the steel to form an oil film.
(2) A reasonable oil seal structure is necessary to protect bearings and lubricants from external contamination. During the operation of the bearing, no matter whether debris or moisture can penetrate into the bearing to prevent damage.
(3) Correct maintenance and maintenance of the key factors to extend the service life of the bearing. For daily equipment maintenance, attention must be paid to the cleanliness of the bearing grease and the selection of appropriate maintenance tools.
(4) Do not mix incompatible greases. If two kinds of incompatible greases are mixed, the consistency will usually become soft. In the end, the bearings may be damaged due to the easy loss of grease. If you don't know which grease the bearing originally used, you must first remove the old grease inside and outside the bearing before adding new grease.
The classification of oils is mainly based on temperature and working conditions:
Greases can be classified according to their allowable operating temperatures. The consistency and lubricity of greases are affected by the operating temperature. Bearings operating at a certain temperature must be selected to have the correct consistency and good lubrication at the same temperature. Grease is manufactured in different operating temperature ranges and can be roughly classified into low temperature, medium temperature and high temperature greases.
If the grease is not properly selected, all bearing protection measures are in vain. It is important that the base oil viscosity of the grease provides sufficient lubrication at the operating temperature, mainly due to temperature. As the temperature rises, the viscosity of the base oil decreases, and the viscosity of the base oil increases as the temperature decreases.
