| Abstract:Accumulative hydro-hammer is of reacting type with low energy consumption, small displacement, large impact power and high energy efficiency. Take the example of internal valve structure, the paper introduces the hydraulic accumulative hydro-hammer about its structure features and working principles, and elaborates the developing process, technical advantages and application effects. The existing problems and the improvement suggestions are also put forward. |
