冲击应力波形不仅决定了岩石破碎效果,而且影响到钻具使用寿命。本文根据J—10O潜孔冲击器的研究,介绍了改善冲击应力波形、提高冲击器活塞寿命的方法和经验。
Impact stress waveform not only determines the rock crushing effect, but also affect the life of the drilling tool. Based on the research of J-10O DTH, this paper introduced the method and experience of improving the impact stress waveform and improving the lifespan of the impactor.
