The drilling rig is powered by a diesel generator. The AC power from several diesel generators controls and drives drawwork, mud pumps,rotary table drive motors, motor-driven drawwork, mud pumps and rotary tables via SCR or VFD systems. Drilling rig adopts K type mast, low installation, overall release; base with parallelogram structure, low installation, use drawwork tension to rise in place; Drawwork main brake using hydraulic disc brakes, auxiliary brake for electromagnetic eddy current brake or Eaton brake; VFD drive of the rig drawwork, auxiliary brake can use energy braking; drive turntable motor through two gearbox drive rotary table.
