What are the factors that affect the quality of lubricating oil for Volvo diesel generator sets?

For the factors that affect the quality of Volvo diesel generator set lubricating oil, we should know that the oil pressure of Volvo diesel generator set reflects the technical condition of the lubrication system. If the oil pressure is too low or too high, it will affect the lubrication quality of the Volvo diesel generator set. Once the oil pressure is abnormal, immediately find out the cause and eliminate it. Oil pressure is always low. No matter what speed or temperature the engine is at, the oil pressure indicated by the oil pressure gauge is always lower than 69kpa, and the oil pressure warning light flashes. The main reason is:
The oil quantity and quality of the Volvo diesel generator set does not meet the requirements. If there is too little oil in the sump; the oil becomes thinner and deteriorates, and the viscosity decreases; water and diesel are mixed in the engine oil. The oil pump is seriously worn or improperly assembled, the oil pressure of the pump cannot meet the requirements, and there is too much oil leakage in the pump. The oil collecting screen or filter is seriously blocked by sludge, and it is difficult for the oil to enter the main oil passage.
The oil pump inlet pipe joint is not tightly sealed, and the oil absorption phenomenon is serious. The lubricating oil circuit leaked seriously, causing a large amount of oil in the main oil passage to flow back to the oil pan from the leak to relieve pressure. The leaking parts mainly include: loose process oil plug on the body; oil pipe rupture; loose screw plug of crankshaft journal centrifugal purification oil chamber; too large matching clearance of crankshaft bearing or cam bearing, failure of oil pressure gauge and sensing plug (remove sensor If the pressure returns to normal at this time, it means that the sensing plug is damaged).
The above is the content of the factors affecting the quality of Volvo diesel generator set lubricating oil.
