2、 Lathkar ;S. K. Basu Abstract Oil contamination is the major source of failure and wear of hydraulic system components. As per literature survey, approximately 70 % of hydraulic system failures are caused by oil contamination. Hence, to operate the hydraulic system reliably, the hydraulic oil should
3、 be of perfect condition. This requires a proper Contamination Management System which involves monitoring of various parameters like oil viscosity, oil temperature, contamination level etc. A study has been carried out on vehicle mounted hydraulically operated system used for articulation of heavy
4、article, after making the platform levelled with outrigger cylinders. It is observed that by proper monitoring of contamination level, there is considerably increase in reliability, economy in operation and long service life. This also prevents the frequent failure of hydraulic system. Keywords： Oil
5、 contamination; RPN; FMEA ; Failure prevention Introduction The development of advance technologies to meet todays requirement for compactness needs sophisticated high pressure system. For reliable and efficient operation, a high quality and clean oil is required. Oil contamination is the major sour
6、ce of failure and wear of Hydraulic system components. As per literature survey approximately 70 % of hydraulic system failures are caused by oil contamination 1. Detailed study reveals that major causes of failure of pumps, valves, actuators are due to contamination. The contamination once developed/ingressed in the system, while circulating in the system, damage the surface of component or stop the movement of valve spool/other moving parts resulting in failure of the system. This pap
