Electric
Drive / Compound Drive Drilling Rigs
■ The drawworks and mud pump are driven by
diesel engine +hydraulic coupler (torque converter) + integral chain compound
box, while the rotary table by AC VFD or DC motor, to realize stepless speed
regulation. The drilling performance has greatly improved.
■ The modules of rig are laid out in the way of
front high rear low, and the power drive system will be installed in the low
position.
■ The drawworks is designed to have an integral
chain driving mechanism, remote air-controlled mechanical gear-shifting. A hydraulic
disc brake (a band brake is optional) is adopted to be main brake, an eddy
current brake as auxiliary brake.
■ The substructure is designed to be of
piled-box-type, or front-swing-up
rear-box type.
■ The compound box can be fitted with
energy-saving generator and automatic blower.
■ An independent auto driller by motor is
equipped.
■ Independent driller control cabin,
centralized electric / air / hydraulic controls, unified layout of instruments.
The driller's operations are simplified and intelligentized. The travel block
realizes intelligent control to avoid collision and collision.
■ An integral guiding rail can be fitted for
cluster well operations.
■ Network electric drive rigs are also
available (motor hydraulic coupling set for electric motor).
