立轴式回转钻机液压系统升级及应用

Upgrading of Hydraulic System of Spindle Rotary Drilling Rig and the Application

摘要:

机械传动、液压给进的立轴式钻机，是当前国内广泛应用的一种主流机型，液压系统是立轴式钻机的重要组成部分。针对主流深孔立轴式岩心钻机液压系统存在的问题，通过采取增大液压元件的额定流量、加大油管的通径、对油箱部分进行完善等措施，对立轴式回转钻机的液压系统进行了升级改进，并经实践验证取得了较好的效果。介绍了立轴式钻机液压系统优化升级的主要措施及其实际应用效果。

Abstract:

Spindle drilling rig, with mechanical transmission and hydraulic driving, is still a kind of main model widely used in China at present, hydraulic system is an important component of the whole rig. Aiming at the existing problems in the hydraulic system of deep hole spindle drilling rig, upgrading improvement was made and good effect was verified by practice. The main measures of optimization and upgrading of spindle rotary drilling rig and the practical application are introduced in this paper.
