Device for Protection Against Hydraulic Shocks of Multi-Stage Pressure Hydraulic Transport Systems

Pipeline hydrotransport systems began to develop rapidly from the second half of the last century. This was especially the case in the mining and mineral industries, when it was used for hydraulic transportation of loose solid materials. One of the fragments of the fundamental works performed by the author at G. Tsulukidze Mining Institute – the construction performance and working principle of the hydraulic shock protection device of multistage pressure hydraulic transport systems – is reviewed. The construction includes a pneumohydraulic accumulator, the body of which is connected to the suction pipe of the pumping unit through a tube on which a foot is mounted, and the bottom is connected to the necessary pipeline with a transfer pipe. Additionally, reverse valves are installed on the supply pipe and the transfer pipe.
