ZJ120DB Drilling Rig

Features:

The drawworks is driven by two AC motors with 1+1R/2+2R step-less speed, and reversal will be realized by AC motor reversal

The mud pump is driven by AC motors, which are mounted on the rear skid of mud pump, with V-belt transmission and simple structure

The independent driven rotary table runs with 1+1R/2+2R step-less speed and reversal will be realized by AC motor reversal

Using AC-DC-AC drive technology, rotary table and drawworks are four quadrant running and full digital vector control.

Single drum, gear driven and one/two shifts smooth speed change drawworks is simple in structure and reliable in operation.

Feed back/Dynamic brake is adopted to replace eddy current brake as auxiliary brake.

Automatic drilling is obtained by drawworks main motor or an independent motor. Intellectual position control for traveling block prevent crown block and rotary table from collision.

Real time communication and network is available by using PROFIBUS technology

K type mast is suitable for install top drive system

Sling shot or swing up substructure and mast are used so that all the equipment can be installed at lower position
