The oilfield pumping unit kowtow machine control system using D71 inverter has been put into operation for more than three years, and has achieved good economic and social benefits:


  • The control device operates reliably, has good environmental adaptability, can resist harsh environments such as oil pollution, dust and damp heat, and has a low failure rate; 

  • The extraction speed can be adjusted dynamically, saving energy and increasing crude oil production at the same time;

  • Excellent current limiting characteristics, strong overload capacity, can effectively reduce frequency conversion overload, overcurrent protection, and maximize production continuity.
