ZJ50 / 3150D Rig
Z.50/3150D rig adopts 3 sets of CAT3512 diesel generator sets as the main power. The 600V50Hz AC is rectified 0 ~ 750V Dc by SCR
cabinet to drive YZ08/YZ08A series DC motor for Drawworks, rotary table and mud pumps. Drawworks is driven by 2 sets of motors,2 sets
of mud pumps are separately driven by 2 sets of motors. Rotany table is driven by 1 motor, electrical transmission system is one-two contro
ipe, AC-SCR-DC transmission, Front open-face mast. swing up substruclure, hoisted by Drawworks power. main brake of Drawworks is
hydraulic disc brake and the auxiliary brake is magnetic eddy current brake.
1.Adopt swing up or slingshot substucture. Substructure, mast and al equioments on the foor are instaled at low position mast and
substructure are raised up at once by Drawworks power. Have advantages of dismounting convenience, quick-carrying, entire movement
and installation, etc
2.Drill arrangement meet the requirement of explosion-proof, safety, driling engineering and equipment installation, disassembly and
convenient maintenance.
3.The Drawworks, rotary table and mud pump can realize independent step less speed regulation, has provided the safeguard for
optimizing drilling technology.
