Abstract: | The running of the electro-hydrostatic driving groups of the rotary system belonging to the large diameter drilling rigs is characterized by a dynamic regime, determined by the transitory phases of the drilling process, by the proper drilling process, and by the accompanying phenomena. In the work, the stand built up for the non-stationary hydro-mechanical process research in the frame of these driving groups, the measuring instruments and the used strain gauge transducers, as well as some aspects regarding their calibration, are presented. The stand represents the rotary system of the drilling rigs F320-3DH-M and F400-4DH-M in natural size and from dynamic point of view. |
