Research on the Correlation Application of Marine Lubricating Oil Technical Indicators

Abstract

In order to timely grasp the running state of ship equipment lubricating oil, reduce serious or sudden equipment failure caused by lubrication problems. The ship lubricating oil was monitored to analyze the correlation between the pollution degree of lubricating oil and the content of wear particles, the correlation between the content of ferromagnetic particles and the ferrography analysis technology, and the correlation between additives and physicochemical indexes. The results show that the rate correlation between the wear intensity index of lubricating oil and the pollution degree is as high as 0.993. The correlation coefficient between the PQ index of lubricating oil and ferromagnetic substances was as high as 0.995, and the contents of the two were approximately equal. The correlation was very obvious, and the standard deviation was only 0.32, with little difference. Ammonium thiophsphonate has a significant positive impact on the Four-ball PB value of the lubricating oil, Oil sludge quantity and the phosphorus retention of the oil after oxidation. Sulfurized olefin has a significant positive impact on copper corrosion. Amine sulfuric-phosphoric diester has a significant positive impact on the kinematic viscosity of the lubricating oil at 100°C. This method can enable relevant personnel to obtain a small number of test results, so as to analyze the interaction between particulate matter and organic fluid in ship lubricating oil and the wear and tear of mechanical equipment, so as to have a more comprehensive grasp of the equipment, make timely maintenance arrangements and reduce the sudden failure of the equipment.
