What are the requirements for lubricant grades and temperatures for large-scale units?
Thread Content
How is the lubricant for large-scale units selected, and what impact does viscosity have on the operation of these units?
1. The model of lubricating oil to be used is specified in the design documents for each large-scale unit. 2. Viscosity is crucial for the lubrication of bearings; high viscosity leads to increased energy consumption, while low viscosity causes the bearing temperature to rise, potentially resulting in severe wear of the bearing. 3. Temperature has a significant impact on the viscosity of lubricating oil; generally, the temperature of the lubricating oil in such systems should be around 40 degrees, with no more than 45 degrees.
Reply to 2# mmhsz321: So, what determines the lubrication viscosity for the machine units? Is it the mode of exercise or the power load?
The principle is generally to use low viscosity for high speeds and light loads, and high viscosity for low speeds and heavy loads
