| 中文摘要:水压式凿岩破碎冲击器与液动冲击器的工作机理有着本质的区别，它有着很高的工作效率和能量转换率，凿岩速度大大高于气动潜孔锤，但这种水压冲击器不适合泥浆驱动。转阀式水压冲击器的配流不同于以往的配流方式，可能更适合泥浆介质驱动。 |

| Abstract:There is an essential difference in the working mechanism between hydraulic rock drilling impactor and hydro-hammer; with very high working efficiency and energy conversion ratio, the rock-drilling velocity of hydraulic rock drilling impactor is much higher than pneumatic DTH hammer but not suitable for mud driving. While the flow distribution mode of revolving valve hydraulic impactor is different to the previous flow distribution modes, and perhaps more suitable for mud medium driving. |
