摘要
冲击器是潜孔钻机的主要部件 ,它的质量好坏直接影响着钻孔速度和钻孔成本 ,通过J 2 0 0C型冲击器在贵州铝厂现场试验 ,证明新型冲击器比原有冲击器的钻孔速度提高 43 %。
The impacter is the main component of down hole driller.Its quality influences directly drilling speed and drilling cost.J 200C impacter is tested on site of Guizhou Aluminium Factory.It is proved that the drilling speed of the new mpacter is 43% faster than the primal impacter.
