Analysis of the factors affecting the likelihood of the appearance of a category of malfunctions of parts in the hydraulic excavator

Аннотация

This article analyzes the main malfunctions of Quarry hydraulic excavators that occur in hydraulic systems, and presents the breakdown of hydraulic parts in a certain state and disconnections into classes as a result of intensive erosion of hydraulic systems during the period of operation. In addition, on the basis of logical and probabilistic relations, an analysis of the fault tree of hydraulic systems was carried out, determining the shares of the interruptions of the hydraulic parts of the quarry hydraulic excavators in the overall working process.
