ZJ40 / 2250D Rig

ZJ40/2250D dilling rig is DC drive module. Drlling rig adopts DC drive,full digital DC control system.Drawworks, rotary table and mud pumpis driven separately, drawworks, mud pump adopts one-to-two control, rotary table is the " one-to-one" control. The three generator setsinterconnection,though three SCR control cabinets, control respectively 7sets DC motors: 2 sets motors are compounded to driveDrawworks,1 set drive rotary table individually, another 4 sets motor, each two are compounded to drive 2 sets 1300 HP mud pump.

Feature：

1.The substructure adopts modular structure, using pin connection between block and block, realizing to quickly move.

2.Mastis front open-face, K type,five sections of mast is whole tower structure which can be installed with crown and move as a whole.Supporting leg is base seat under substructure, stability is good, using Drawworks power raising or lower as a whole.

3. Drawworks is driven by DC motor, power utlization rate is high,total number of Drawworks shift can be up to 4+4R,can realize steplessspeed regulation.
