Features of AC VF Drive Drilling Rigs
• Drill floor equipment installs at ground level and rigs up integrally with the mast
• Single shaft AC VF gear drives drawworks; Drawworks main brake is hydraulic disc brake, assistant brake is dynamic brake, meanwhile drawworks is equipped with motor auto-bit-feeding device
• Traveling block position automatic control system prevents “collide up and impact down” accidents. Position control is achieved by real-time detection of traveling block position and PLC calculation and analysis. When traveling block reaches alarming position, “soft-stop” control procedure of “alarming-slowdown-stop” is triggered automatically. Accurate real-time position indication of traveling block makes driller’s operation easy.
• Integrated design of mechanical, electrical, digital control and communication, adopting up-to-state vector control, VF, digital control and field bus communication technology
• Performance and technical parameters comply with SY/T5609—1999 standard.
• Main parts conform to API spec and marked with API monogram.

• Key mechanical parts conform to API spec and marked with API monogram
• Powered by 4 parallel 2000 (3000) series diesel engines + hydraulic torque converter (coupling) + chain box drive
• Drawworks drum is grooved. The main brake is hydraulic disc brake and assistant brake is electromagnetic eddy current brake. Drawworks adopt pneumatic tube clutch for remote control, operating easily and quickly.
• Drawworks adopts split type arrangement and installed above and under the drill floor. Heavy main drawworks is placed at lower position. Drill floor is box-on-box type structure, compact, easy to rig up.
• Rotary table is independently driven by AC VF motors for 0-240 r/min stepless speed regulation thus eliminating rotary table and mud pump power conflicts which occur in uniform driving system of mechanical rig, thus satisfying quick drilling. AC is provided by auxiliary generator set.
