Shower room pulley working temperature special lubrication
It is generally used for 90 ℃ (volume temperature of oil) or 200 ℃ (bearing temperature), and Shower room pulley special lubrication is adopted.
Oil can be used up to 250 ℃.
It is generally used below 120 ℃, and it can be used up to 220 ℃ with special grease or shortening the grease change cycle.
Allowable speed.
(DN value)
4.5～5 × 105。
3~5 × 105。
Greases with the same thickener and similar base oils can generally be mixed without adverse effects.
Selection of lubricating grease
When selecting lubricating grease, it is mainly considered according to the working temperature, load and speed of the bearing.
The lubricating performance of grease depends on the base oil, and the selection of base oil is determined according to the purpose and service conditions of grease. The lubricating grease used for low temperature, light load and high-speed bearings shall be low viscosity base oil, such as instrument oil, turbine oil, etc. The lubricating grease used for bearings with low temperature, medium load and medium speed can use mechanical oil and internal combustion engine oil as the base oil. Cylinder oil can be used as base oil for lubricating grease used for bearings with high temperature, heavy load and low speed. Synthetic base oil can be selected for special Shower room pulley lubrication conditions.
