Compressor lubricant issues
Thread Content
Why is the lubricating oil from the compressor unit returned to the oil tank by gravity, and why aren’t the bearings lubricated while submerged in pressurized lubricating oil? Thank you!
Firstly, it enhances the lubrication effect as well as the duration for which the lubricant remains in place. If lubrication is carried out under pressure, it requires significant resources in terms of design and implementation; moreover, oil-free lubrication or excessively high oil temperatures can lead to bearing damage
How to improve the lubrication effect? Why does this increase the dwell time? High consumption is no problem, but how does oil-free lubrication occur under pressure? Why does high oil temperature occur under pressurized flow? I hope you can continue to answer my questions?
First, the original poster should learn about the various methods of bearing lubrication. By “submerged,” does the poster mean oil immersion lubrication? What is the speed of the compressor? If the speed is high, oil immersion lubrication should not be used; circulating lubrication might be appropriate. If the circulating lubrication pressure is too high, it is not conducive to the formation of an oil film thickness.
If there is pressure, the flow rate increases significantly; naturally, the residence time of the oil becomes shorter. When pressure is applied, it is done through other means, and once those means fail, oil-free lubrication occurs
