What is the impact of lubricant viscosity and density on the amount of lubricant required?
Thread Content
Before starting the equipment, lubricant is added to it; the oil level is around 1/2. The equipment operates at a temperature of about 400°. The higher the temperature, the lower the viscosity and the thinner the lubricant, which could cause the oil level to rise? Does lubricating oil also apply to the law of conservation of energy? Before operation, the 206 seal in our factory was filled with oil to halfway up the oil cup. However, after operating for about 400 degrees, the oil level in the cup reached its maximum. We checked the seal as well, and no leakage was detected. What could be the reason for this?
There is a high likelihood of leakage, and the volume change due to thermal expansion and contraction is not that significant
The expansion of the liquid is extremely small! Can you get much more boiling water by heating a pot than by adding cold water? It’s practically negligible! The starting point of the problem is wrong! Liquids are incompressible!
