| Summary: | The results of the research of processes in hydraulic systems of hydraulic drilling rigs of geological exploration boreholes are analyzed in the paper. The functioning of the flow throttling valves and pressure shift under many different schemes of connection and different regimes of operating is considered. The various patterns of the flows of the hydraulic fluid through the local resistances are revealed. The evaluation of the flows patterns of hydraulic fluid in the hydraulic borehole system is done, as well as the dividing into the different areas and subareas and its application in regulating equipment. The instructions of their usage in the feed mechanisms of the hydraulic drilling rigs are worked out. |
