Why does a high lubricating oil temperature lead to low pressure of the compressor’s lubricating oil? Please explain this to me
There is a certain relationship between the density of lubricating oil and temperature and pressure; the density decreases when the oil temperature is high and increases when the temperature is low. Therefore, the oil pressure is lower at high temperatures and higher at low temperatures.
Personally, I think it is because the high temperature reduces the viscosity of the lubricant, thereby affecting the pressure. I would appreciate it if experts could correct my personal understanding.
