动能式自回转液压潜孔冲击器

Kinetic energy self-propelled rotary hydraulic DTH hammer

介绍了一种新型动能式自回转液压潜孔冲击器,并且通过对比分析探讨了其与传统气动潜孔冲击器的区别。结果表明,该冲击器避免了活塞与钎杆的碰撞,能量利用率高,破碎岩石的效率高。

This paper introduces a novel kinetic energy self-propelled rotary hydraulic DTH hammer and discusses differences from the traditional pneumatic DTH hammer. The result shows that this DTIt hammer avoids the collision of pistons and drill shanks and has higher utilization ratio and higher efficiency of breaking rocks.
