VFD and Control System
DDPM-DW (Drawworks) directly driven wire drum of the drawworks system, eliminating gearbox, air clutches and other associated accessories. The unison with the VFD the motors operation allows the drawworks system to smoothly achieve self-lifting, lowering, and hoisting with absolute zero slip ratio.
DDPM-DW improves the efficiency of drilling operations by increasing; performance and safety factor, while reducing energy consumption, maintenance, footprint, and rig weight.
• Intelligent Systems: The operator need only operate a shift handle for convenient control of the speed to the drawworks lifting, lowering and hovering with absolute zero slip ratio.
• Increased Efficiency: The DDPM-DW efficiency is up to 97.1%, and its directly driven wire drum provides 6% higher transmission efficiency and 11% faster hoist speed.
• Overload Capacity: the Breakdown Torque is up to 1.8 times the Rated Torque, allowing smooth control of any situation.
• Less Maintenance: directly connecting to the drawworks system eliminates the gear box and all associated maintenance to it.
• Reduced Weight & Footprint: DDPM-DW reduces your rig weight with a 20% to 30% reduction in footprint.
