ZJ20DBS Oil drilling rig

Oil drilling rig,mobile drilling rig,rotary drilling rig Model:ZJ20DBS,ZJ30DBS,ZJ40DBS,ZJ50DBS,ZJ70DBS

1) Adopting digital-control technique, computer technique and integrating mechanics, electricity, hydraulics and pneumatics into design, the intelligent control for drilling rig is realized through PLC technology and touch screen.

2) Adopting AC VF motor drive, the drawworks , rotary table and mud pump achieves stepless speed regulating function .

3)The drawworks is a structure with single shaft, gear transmission, stepless speed regulating, the brake adopts hydraulic disk brake and dynamic brake together, with simple structure and reliable performance.

4)Adopting constant WOB auto-bit-feed device, the WOB is controlled precisely.

5)The rig operation has realized the functions for collecting, display, storing, printing and transfer of drilling parameters, and the function of multi-points monitoring and communication.

6)The rig operation has realized the full digital-control or digital closed-loop control for traveling block position, trip speed, safety presetting and interlock protection, and preventing collide up and impact down (crown and RT protection) .

7)with the online monitoring system for working s tatus of mechanical, electric, hydraulic and pneumatic implements, failure alarm and failure self-diagnosis has been realized, the equipments can work normally and troubleshooting can be done easily.

8)The driller control cabin is independent and lifted hydraulically (ZJ70DBS), without contacting the drill floor, with little vibration, and convenient for installation and teardown. The driller control cabin is a pressurized unit for explosion proof (certificated). The drillers can fitful all drilling operation parameter setting on the operating chair, the operation manner has been improved and the labor intensity lightened greatly .

9)It can be equipped with rig moving device, satisfying the requirement for cluster well drilling.

10)Satisfying the requirement for TDS installation.
