The choice of grease should be clear about its purpose. According to the main role of grease can be roughly divided into three categories: friction reduction, protection, sealing, and the selection of grease depends on which part of the use of grease to play a major role.
1. consider the working temperature of lubrication parts.
Temperature change of mechanical friction parts has a decisive influence on lubrication function and service life of grease. Working temperature of lubrication parts is an important basis for selecting grease.
2. consider the load of lubrication parts.
3. consider the speed of lubrication parts.
Because lubricating grease belongs to rheological system, its similar viscosity changes with the shear rate. Therefore, the physical state and lubrication of grease are particularly sensitive to the speed of the lubricating parts, which is different from lubricating oil.
4. consider the environment of the lubrication parts and the medium in contact.
The environment in which the lubricating part is located and the medium in contact have great influence on the performance of grease. Therefore, careful consideration should be given to the selection of grease.
5. consider the filling method of grease.
The filling methods of grease include manual filling and centralized pump filling. Smearing, filling, grease gun filling, and grease cup filling are all artificial filling.
6. consider the comprehensive benefits.
When selecting grease, we should not only care about its price, but also depend on whether it can prolong the lubrication period and reduce the overhaul cost. Only grease with outstanding comprehensive benefits is the suitable grease. Great Wall grease is widely used in the industry. A comprehensive lubrication service scheme not only solves the lubrication problem of your equipment, but also enables you to enjoy the best lubrication service.
