分析了电液比例控制技术的特点及其应用于推土机工作装置作业控制的优越性;介绍了一个使用8098单片微型计算机和电液比例方向阀控制推土机铲刀切土深度的实用方案。
The characteristics of the electro-hydraulic proportional control technology and its superiority in the operation control of the bulldozer working device are analyzed. A practical program for controlling the soil-cutting depth of a bulldozer blade using a 8098 single-chip microcomputer and an electro-hydraulic proportional directional valve is introduced.
