Product Description

http://xxxxx/english/products/products.htm Adopt digital-control technique, computer technique and integrated design with mechanical, electric, hydraulic and pneumatic, the intelligent control for drilling rig is realized through PLC technology and touch screen. AC VF motor drive, the drawworks, rotary table and mud pump achieved stepless speed regulating. The drawworks is a structure with single shaft, gear transmission, stepless speed regulating, the brake adopt hydraulic disk brake and dynamic brake together, structure simple and performance reliable. Adopt the constant WOB auto-bit-feed device, patent of Honghua, the WOB control precision is very perfect. The rig realize the function for collecting, display, storage, print and transmission of drilling parameters, and have the function of multi-points monitoring and communication. The rig achieve the full digital-control or digital closed-loop control for travelling block position, trip speed, safety preset and interlock protection, have the function of preventing �collide up and impact down �and preventing �pumping and obstructing�. Have online monitoring system for working state of mechanical, electric, hydraulic and pneumatic implements, failure alarm and failure self-diagnosis system, can hold the working condition of equipments and do troubleshooting easily. The driller control cabin is independent and lifted hydraulically (ZJ*0DBS), not to contact with drill floor, little vibration and convenient to installation and teardown. The driller control cabin is a pressurization unit for explosion�proof (certificated). The drillers can complete all drilling operation sitting on the operating chair, radically remodel their operation manner and working condition, lighten their labor intensity, change them from experience worker to knowledge worker. Can be equipped with rig moving device, satisfy the requirement for cluster well drilling. Satisfy the requirement for TD
