Gravitational Potential Energy Recovery and Recycle of Rotary Drilling Rig Kelly Bar
Abstract:
In order to improve the economic benefits of tunneling to rotary drilling rig ,in this paper ,the rotary drilling rig main winch hydraulic system was improved ,by increasing an hydro pneumatic accumulator storage and releasing gravitational potential energy of kelly bar ,as well as increasing reversing motor and the main winch motor to form a hydraulic transformer .So ensured the high pressure when the energy release and reduced the rotary drilling rig engine power ,what’s more ,this system’s feasibility had been verified by theoretical calculation .
