Development of Energy-saving Control Technology for Rotary Drilling Rigs
As a high-power engineering machinery,rotary drilling rigs have high energy consumption,low energy utilization rate,and low matching between various systems,which are important reasons for energy loss.This article starts with the working principle of rotary drilling rigs and briefly analyzes the power system of rota-ry drilling rigs,from three directions:hydraulic system control,power system control,and overall coordinated control,This article introduces various energy-saving control technologies for current rotary drilling rigs,inclu-ding hybrid power technology,main winch lowering technology,mast/luffing regeneration technology,power head multi gear technology,and power head pressure fast lifting technology.It is hoped that this will be benefi-cial for improving the technical level of rotary drilling rigs.
