摘要
全液压瓦斯抽采机钻机目前多采用阀控变量技术,泵控变量技术仅在新型钻机上获得应用。介绍并研讨瓦斯抽采钻机液压系统主要回路型式和泵控变量技术的应用现状。
The valve-control technique is adopted on the most of existing hydraulic gas drainers, but the pumpcontrol technique is merely used on some new drainers. The main types of hydraulic system on gas drainers and the application of pump-control technique to them are introduced and discussed.
