液压技术的应用有力地推进了各类地质钻机,尤其是工程地质钻机的发展,显示出极大的优越性。本文主要结合国内液压技术发展的实际,探讨工程地质钻机主要机构液压回路方案的设计,以及整机液压系统的合理组合。所论述的问题,很多也适用于其它用途的地质钻机。 The application of hydraulic technology has effectively promoted the development of various types of geological drilling rigs, especially engineering geological rigs, showing great superiority. This paper mainly based on the actual development of hydraulic technology in China, discusses the design of the hydraulic circuit scheme of the main organization of engineering geological drilling rig and the reasonable combination of the hydraulic system of the whole machine. Many of the issues discussed also apply to other geological drilling rigs.
