ZJ30 Drilling Rig

1.ZJ30 Skid mounted drilling rig 2.drilling depth:2000-3000m 3.Max.hook load:1700KN 4. API Specification

ZJ30/1700 Drilling rig has four choice of driven mode according to your requirement: mechanical driven(L), combination driven(LDB), DC motor driven(D), AC frequency variable motor driven(DB).

Main components/parts,such as a crown block,traveling block,hook,swivel, rotary table,mast & substructure are in compliance with API standards, and can be stamped with API monogram.

Design features:

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. To reduce driller and drilling workers' labor intensity and promote the drilling automation, the drilling rig is equipped with a hydraulic disc brake and some mechanized wellhead tools to realize the remote control. For AC/VFD electrical driven type, the drawworks is equipped with an emergency motor to greatly promote the capacity for handling any accidents.

3. The brake system of drawworks adopts hydraulic disk brake, with electromagnetic brake for DC/SCR drive drawworks and mechanical drive drawworks, dynamic brake for AC/VFD drive drawworks, with simple structure and reliable performance.
