How to choose grease suitable for vane pump special oil pump motor?

To improve the service life of the motor, the first thing is to solve the bearing system problem. The necessary condition for the normal operation of the bearing system is good lubrication of the bearing. Grease is critical in order to achieve optimum bearing lubrication. The following Dalan Motor Xiao Bian talks about how to choose the right grease for the vane pump special oil pump motor.

Select bearing grease considerations:

(1) The bearing grease must have a rust proof effect and good adhesion. The rust inhibitor in the grease is preferably insoluble in water, and the grease can adhere to the surface of the steel to form a film of oil.

(2) A reasonable oil seal structure is necessary to protect the bearings and lubricants from external contamination. During the operation of the bearing, no impurities or moisture can penetrate into the bearing to prevent damage to it.

(3) Correct maintenance The key factors that extend the service life of the bearing. For routine equipment maintenance, attention must be paid to the cleanliness of the bearing grease and proper maintenance tools.

(4) Do not mix incompatible oils. If two incompatible greases are mixed, their consistency will usually become soft. Finally, the bearing may be damaged due to the easy loss of grease. If you do not know which type of grease was originally used in the bearing, you must first remove the old grease inside and outside the bearing before adding new grease.

The classification of grease is mainly based on temperature and working conditions:

Greases can be categorized according to their permissible operating temperatures. The consistency and lubricity of the grease 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. Greases are manufactured in different operating temperature ranges and can be roughly classified into greases for low, medium and high temperatures.

If the grease is not properly selected, all bearing protection measures are in vain. It is important that the base oil viscosity of grease is sufficient to provide sufficient lubrication at the operating temperature, which is mainly affected by the temperature. As the temperature rises, the viscosity of the base oil decreases, and the viscosity of the base oil decreases as the temperature decreases.
