| Abstract: | This paper summarized the phenomena and reasons of common faults for TY180 bulldozer working member hydraulic system based on the analyses of its working principle,structure and typical faults.Corresponding measures were put forward to eliminate the faults.By causal analysis and fault tree analysis(FTA),the fish bones chart of shovel's motionless or weakness rising and fault tree of scarifier cylinder fixed are given out to explicitly describe the logical relationship between causes and corresponding results of the faults.Practice has proved it is possible to rapidly diagnose and eliminate some faults of bulldozer working member hydraulic system with the proposed methods to improve the machine reliability.It provides certain theoretical basis and practical references for fault detection and maintenance of hydraulic system of construction machinery. |
