本文简要地论述了液压泵、马达在全液压钻机中的地位。根据金刚石钻进的特点,扼要地论述了全液压钻机对液压泵、马达的要永。选择了具有通轴结构的滑履式轴向柱塞泵、马达做为全液压钻机的主传动元件。综合了国内各家的设计计算方法,并参考了国外有关资料,确定了设计计算方法,进行了液压泵、马达的主要磨擦付的水力设计及80泵的计算。然后经过试验台的寿命试验,两磨擦付运转正常,说明了所确定的设计计算方法是可行的。 This article briefly discusses the hydraulic pump, motor position in the full hydraulic drilling rig. According to the characteristics of diamond drilling, a brief discussion of the full hydraulic drilling rig, hydraulic pump, motor to Yong. The choice of a through-axis structure of the axial piston pump, the motor as the whole hydraulic rig’s main transmission components. Based on the data from abroad, the design and calculation methods are determined and the hydraulic design of the main friction of the hydraulic pump and the motor and the calculation of the 80 pump are integrated. Then after the life test of the test bench, the two rub rubs pay to operate normally, which shows that the determined design calculation method is feasible.
