AC VF Drive Drilling Rigs

AC VF Drive Drilling Rigs Features 1. Drill floor equipment installs at ground level and rigs up integrally with the mast 2. 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 3. 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. 4. Integrated design of mechanical, electrical, digital control and communication, adopting up-to-state vector control, VF, digital control and field bus communication technology 5. Performance and technical parameters comply with SY/T5609_1999 standard. 6. Main parts conform to API spec and marked with API monogram.
