Detailed Description

VFD Drilling Rigs

● The drawworks is driven by two VFD 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 VFD 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 prevents 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 applied so that all the equipment can be installed at lower.
