ZJ30 / 1700DB Rig
ZJ30/1700B rig is driven by Ac variable frequency motor, According to the function is divided into following major areas: driling platform
power and electric supply area, pump area, solid control area, ol tank area and other devices. t is suitable for side driling well, directiona
well and vertical well drlling operation within 3000m. Drawworks and rotary table adopt independent driving mode. Drawworks is driven by
one 600kW AC variable frequency motor;rotary table is driven by one 300kW AC vaniable frequency motor. Two sets of F-500 mud pumps
are respectively driven by the other two YJ23A500kW AC variable frequency motors. The speed of motor used to driving drawworks is
changed by one set two shits transmission to drive drawworks through chain box, and to realize 2+2R gears. Rotary table adopts direct
connection between motor and rotary through transmission shaft.
1.The rig adopts modular design,and installation & transportation times is less, which can realize to move and disasembely quickly
2.Mast is front open-face,"K" type mast. lt is two-section telescoping structure. lt raising & lower by its own power, substructure is high-ow
position hydraulic telescoping structure, installation on low position and raising integrally
3.The rig is driven and controlled by AC frequency conversion mode, which has special driller console.All air hose and ol tubes adopt quick
acting coupling and are remarked clearly
