系列高效液动锤的研究与应用

Study and Application of High Efficiency Hydro-hammer

摘要:

传统的液动潜孔锤适应孔深较浅、孔径范围小。传统的正作用式液动潜孔锤阀、锤的工作弹簧对冲击能量影响大、弹簧寿命短，易损坏，其在不正常工作时将截断液流通道，必须提钻检查，否则将会出现烧钻事故;传统的双作用液动锤主要是靠锤、阀各自的上下活塞面积差产生的压力增高而工作，运动密封副多，对冲洗液质量要求高、运动阻卡几率大，固定式节流环对冲锤下行做功将产生一定的阻尼作用。YZX系列高效液动潜孔锤和SYZX系列绳索取心液动锤克服了传统液动锤的诸多不利因素，通过从基础理论研究、结构优化设计、产品规模开发，使我国液动锤技术得到了大幅度的提升，并作为一种高效、简便、节能的新产品，在生产实践中获得了良好的应用效果。

Abstract:

As the new products with high efficiency, convenience and energy-saving, YZX series high efficient hydro-hammer and SYZX series wire-line coring hydro-hammer overcame the unfavorable factors of traditional hydrohammer. By the basic theoretical research, structural optimization design and scale development, hydro-hammer technology has been largely improved in China and good application result is achieved in construction practice.
