轮式推土机广泛应用于矿山开采、道路维护、农业、建筑业等工程上,其工作装置液压系统故障发生率比较频繁。本文以834H型轮式推土机为例,介绍其工作装置液压系统工作原理,并对工作装置无动作及动作缓慢的原因进行分析。1.液压系统工作原理(1)主液压回路834H型轮式推土机液压系统由主液压回路和先导液压回路组成,其主液压回路主要由工作泵1、主安全阀2、举升缸3、液压油箱4、
Wheeled bulldozers are widely used in mining, road maintenance, agriculture, construction and other projects, the working unit hydraulic system failure occurs more frequently. In this paper, the 834H bulldozer is taken as an example to introduce the working principle of the hydraulic system of the working device and to analyze the reasons why the working device does not move and the action is slow. 1. Hydraulic system works (1) the main hydraulic circuit 834H wheel bulldozer hydraulic system consists of the main hydraulic circuit and pilot hydraulic circuit, the main hydraulic circuit consists of working pump 1, the main relief valve 2, lift cylinder 3, hydraulic Fuel tank 4,
