对全液压推土机的特点和液压系统的组成进行了介绍,给出了发动机与液压泵匹配控制的方法,结合国内首台小马力全液压推土机,以铲掘工况为例,计算了发动机转速与液压泵排量的关系,对实现液压泵与发动机的控制、提高全液压推土机的作业生产率有重要的作用。
The characteristics of full hydraulic bulldozer and the composition of hydraulic system are introduced. The matching control method between engine and hydraulic pump is given. Combined with the first small horsepower full hydraulic bulldozer in China, taking the shoveling working condition as an example, the relationship between engine speed and The relationship between displacement of the hydraulic pump has an important role in achieving the control of the hydraulic pump and the engine and improving the operation productivity of the full hydraulic bulldozer.
