When the temperature is high, choose a grease with good oxidation resistance, low evaporation loss and high drop point. When the temperature is low, choose a grease with a low starting moment and a similar viscosity. .
2. The selected high temperature grease should be compatible with the speed of use of the friction pair being lubricated.
At high speeds, high-temperature greases with a large cone penetration made from low-viscosity base oils should be selected; for low-speed greases, high-temperature greases with high-cone penetration grades made from high-viscosity base oils should be selected.
3． The selected high temperature grease should be suitable for the load.
For heavy loads, high temperature greases with high base oil viscosity and high thickener content should be selected. When the load is particularly large, you should pay attention to selecting high temperature grease with extreme pressure additives or fillers (molybdenum disulfide, graphite); at low and medium loads, generally use high temperature grease with short No. 2 consistency soap fiber structure and medium viscosity base oil. .
4． The selected high temperature grease should be suitable for the environmental conditions used
In environments with humid air or contact with water, calcium-based, lithium-based, and lithium-based composites with good water resistance should be used. When there is a lot of dust, thicker (ie higher grade) greases should be selected to ensure tightness. Preferably, impurities can be prevented from being mixed into the friction pair.
In the environment of strong chemical media, high temperature greases such as fluorocarbon high temperature grease, which are resistant to chemical media, should be used.
5. The selected high temperature grease should be compatible with the lubrication method of the friction pair
In the case of centralized grease supply, 00 ~ 1 high-temperature grease should be selected; for parts filled with grease guns, grease cups, etc. regularly, 1 ~ 3 high-temperature grease should be selected; , Should use No. 2 or No. 3 high temperature grease.
