Reasons for low compressor lubricating oil pressure
Thread Content
My unit is a piston compressor. What could be the reason for the low pressure of the compressor lubricating oil? What methods can be used to increase the lubricating oil pressure when it is low? Thank you, extra points
1. Low pressure at the oil pump outlet； 2. Clogged outlet filter ； 3. Faulty pressure gauge (pressure transmitter) 4. Clogged pipeline (clogged inlet filter). Solution: Disassemble and inspect the oil pump ； Switch or replace the oil filter element ； Check the pressure gauge or pressure transmitter ； Clean the inlet filter ；
1. The oil suction filter is clogged; remove it and clean it. 2. The oil pressure control valve is malfunctioning; it needs to be repaired or replaced. 3. The gap between the oil pump gear and the pump cover is too large or there is wear; repair or replace it. 4. The crankcase oil level is too low; add oil or allow oil to return. 5. The bearings in various parts are severely worn, resulting in excessive gaps or oil leakage in some oil circuits; these issues need to be inspected and repaired.
Additional note: High oil temperature leads to a drop in oil pressure； Another issue that is not easy to detect is damage such as detachment or breakage at certain lubrication points inside the crankcase.

The original poster’s analysis is absolutely correct; well done.
