【Q&A Question 039】May 29, 2016: What are the reasons for the drop in the pressure of the lubricating oil in the unit? The answer key will be available after responding; scoring is based on answering the key points. 1. Lubricating oil pump issues ； 2. Clogged filter ； 3. High oil temperature ； 4. Degraded lubricant ； 5. Pipeline leaks, etc
1. Oil pump failure 2. Low oil temperature and viscous lubricant 3. Oil pipe leak 4. Instrument detection failure
There is a problem with the lubricating oil pump: the safety valve at the pump outlet is leaking, the overflow valve at the pump outlet is not functioning properly, and the filter at the pump inlet is clogged
There is a problem with the main oil pump. It’s time to replace the lubricant.
1 The fuel tank level is below the minimum level line； 2 Oil filter clogged ； 3 Oil pipeline control valve failed ； 4 The oil pump does not deliver sufficient flow. 5. Oil circuit leakage. 6. The oil cooler is not working properly, resulting in high oil temperature
Pump failure, leakage present, filter clogged
1. Lubricating oil pump issues； 2. Clogged filter ； 3. High oil temperature ； 4. Degraded lubricant ； 5. Pipeline leaks, etc
Fuel pump failures at gas stations, clogged pipelines, high oil temperature, degraded lubricating oil, etc
1. Distortion of instrument signals； 2. Failure of the self-acting lubricating oil control valve ； 3. Leakage in the lubricating oil pipeline ； 4. Caused by leaks or failures in the oil regulation system ； 5. The return tank bypass valve is opened
Excessive clearance in the gear oil pump / Broken oil pipe / Clogged filter / Oil level in the tank / Overly open return valve, etc
