Load Sensing Hydraulic Circuit on Hydraulic Driving Head Core Drill

摘要:

钻探工作对液压钻机的回转、给进和升降液压回路都有性能上的要求，传统的手动控制阀与定量泵组成的普通液压系统技术较落后，对不同地层钻进控制能力和适应性差，而负载敏感液压回路对钻进适应性强，可提高钻进效率，且液压系统能耗少、发热少、传动效率高。介绍了液压动力头岩心钻机的负载敏感液压回路的工作原理，系统的特点及对钻探工作的负载适应能力。

Abstract:

Because of the performance requirements of drill operation on rotating, feeding, hoisting and falling hydraulic circuit for hydraulic drill, the traditional ordinary hydraulic system consisting of manual control valve and pump is considered to be backward, which has poor adaptability in drilling control in different formations. But the load sensing hydraulic circuit has good adaptability for drilling work, which can promote the efficiency of drilling, the hydraulic system is with energy saving, low temperature and efficient transmission. The article introduced the working principle of load sensing hydraulic circuit on hydraulic driving heading core drill, system characteristics and adaptive capacity to drilling work load.
