ZJ50 / 3150D Rig

ZJ50/3150D rig adopts 3 sets of CAT3512 diesel generator sets as the main power. The 600V/50Hz AC is rectified 0~750V DC by SCRcabinet to drive YZ08/YZ08A series DC motorfor Drawworks, rotary table and mud pumps. Drawworks is driven by 2 sets of motors,2 setsof mud pumps are separately driven by 2 sets of motors. Rotary table is driven by 1 motor,electrical transmission system is one-two controltype, AC-SCR-DC transmission. Front open-face mast, swing up substructure, hoisted by Drawworks power, main brake of Drawworks ishydraulic disc brake and the auxiliary brake is magnetic eddy current brake.

Feature：

1.Adopt swing up or slingshot substructure. Substructure, mast and all equipments on the floor are installed at low position, mast andsubstructure are raised up at once by Drawworks power. Have advantages of dismounting convenience, quick-carying,entire movementand installation, etc.

2.Drill arrangement meet the requirement of explosion-proof, safety, drilling engineering and equipment installation, disassembly andconvenient maintenance

3.The Drawworks, rotary table and mud pump can realize independent step less speed regulation, has provided the safeguard foroptimizing drilling technology.
