Electromechnical Drilling Rigs

Electromechnical Drilling Rigs: Electromechnical Drilling Rigs is powered by diesel engines coincident with hydraulic torque converter which drives drilling winch, mud pump, automatic air compressor and energy saving generator by integral chain box drive.Power between power package, transmission unit and work unites is conveyed by cardan shaft. Drawworks equips with the auxiliary drive device to lift up and down the derrick, to automatic driller and boot up in emergency. K type derrick with assembling placed on the ground and raising/ laying down as a whole can equip with top drive; Box on box type substructure(swing-up type for ZJ50 and ZJ70 rigs) ensures conveniently disassemble and assemble, good stability and high safety. Rotary table is driven by Drawworks power through special rotary table drive unites or independently driven by AC VF motors. Feature of Electromechnical Drilling Rig: 1. Drill rig models and basic technical parameters conform to Chinese petroleum industry standards. All main components conform to specifications; 2. Diesel engine drives drilling winch, mud pump, automatic air compressor and energy saving generator by integral chain box, therefore it makes

Our truck-mounted drilling rigs range from 550HP to 1,000 HP. Tips For Inquiries Rig type: Skid -mounted, truck-mounted, or trailer-mounted? Hook load or drilling depth or rig power, better to submit rig specifications list, if not available, we may provide our specification list for your reference

BWH200

This model rig uses full hydraulic control, and the Top drive to drive the rotation of drilling tools with very high drilling efficiency. Reasonable overall layout uses the tractor-mounted or full ground chassis for transportation with good maneuverability. Very flexible in difficult roads and can be widely used in many fields such as resource exploration of hydrology wells, water wells, etc. The top-mounted driving head principal shaft has a great drift diameter, suitable for many kinds of construction work such as slurry drilling and air drilling, , meeting the demands for well-drilling at different terrain strata.

Electric Drive Rig

he drilling rig is powered by a diesel generator. The AC power from several diesel generators controls and drives drawwork, mud pumps,rotary table drive motors, motor-driven drawwork, mud pumps and rotary tables via SCR or VFD systems. Drilling rig adopts K type derrick, low installation, overall release; base with parallelogram structure, low installation, use drawwork tension to rise in place; Drawwork main brake using hydraulic disc brakes, auxiliary brake for electromagnetic eddy current brake or Eaton brake; VFD drive of the rig drawwork, auxiliary brake can use energy braking; drive turntable motor through two gearbox drive rotary table. Electric drive rig performance characteristics: 1.Basic parameters in line with industry standards and regulations, the main components manufactured in line with the relevant norms; 2.SCR and VFD speed control system and digital control technology to flexibly adjust the drawwork lifting speed, rotary table speed and mud pump stroke to improve the working performance and power utilization of drawwork, rotary table and mud pump; 3.The traveling block position to achieve closed-loop control; auxiliary drive to achieve automatic drilling and
