1. The rig adopts DC electric drive mode. From the 4 sets CAT3512B diesel generator power, the inverter drive cabinet after rectifying into 0-750V (adjustable) DC drive drawworks, mud pump, rotary motor, stepless speed regulation.
2.The rig adopts open front derricks, low installation, integral lifting.
3. The base for singleshot structure, all equipment installed on mesa low power integrated hoisting winch.
4.Four shaft hoist winch. Powered by two 750V, 800KW DC motor, the main brake using hydraulic disc brake, brake disc with double water-cooled disc. The auxiliary brake adopts water cooling electromagnetic eddy current brake. Winch configuration overwind valve type and hammer type anti-collision device.
5. A rotary table 1 750V, 800KW DC motor driven by flip chain box, universal shaft driving.
6, Every mud pump with 2 750V, 800KW DC motor driven by the joint group of narrow V. The continuous and steady change stepless speed regulation of DC motor can be realized and the displacement of the pump.
7.Using 5 class drilling mud purification system, it can be very well to remove harmful solid mud in the mud to purify.
