Features:
l 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
l 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
l The independent driven rotary table runs with 1+1R/2+2R step-less speed and reversal will be realized by AC motor reversal
l Using AC-DC-AC drive technology, rotary table and drawworks are four quadrant running and full digital vector control.
l Single drum, gear driven and one/two shifts smooth speed change drawworks is simple in structure and reliable in operation.
l Feed back/Dynamic brake is adopted to replace eddy current brake as auxiliary brake.
l Automatic rig123.net' target='_blank'>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.
l Real time communication and network is available by using PROFIBUS technology
l K type mast is suitable for install top drive system
l Sling shot or swing up substructure and mast are used so that all the equipment can be installed at lower position
