列为回转-冲击式液压凿岩机性能参数的是凿岩机的冲击能量、冲击频率、转速和轴推力。这些参数的最佳组合,可在能量和钎具消耗较少的情况下,保证高速度和高效率地凿岩。在破碎机构和选择合理参数的问题上尚存在一些不同意见。在著作[1]中列举了六种回转-冲击凿岩破碎系统,每一种都具有各自的特点。在回转-冲击凿岩法的应用范围上,意见也不一致。多数作者认为,用这种凿岩方法钻凿普氏硬度系数 f=8～16的
The performance parameters of the rotary-impact hydraulic rock drill are the impact energy, impact frequency, rotational speed and axial thrust of the rock drill. The best combination of these parameters guarantees rock drilling with high speed and high efficiency with less energy and tool wear. There are still some different opinions on the mechanism of crushing and selecting reasonable parameters. In the book [1], there are six types of rotary-impact rock breaking systems, each of which has its own characteristics. In the rotary - impact drilling range of applications, the views are not consistent. Most authors believe that drilling with this method of drilling Platts hardness f = 8 ~ 16
