Abstract
The sources of oil contamination in hydraulic system of boom-type road header are analyzed, and the important significance of the oil pollution control is pointed out. Then, the mathematical equationof the hydraulic contamination control system is established and the related influencing factors are analyzed. The factors that affect oil contamination of boom road header are presented to reduce the probability of failure, and then improve the reliability of hydraulic system. It is very useful for the oil contamination control of hydraulic system.
