| 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. |
