摘要
就射流相对于刀具的四处不同位置对切割效能的影响进行了测试。并对射流位置与刀具前方岩石碎块形成的关系进行了分析。在射流作用下,切割深度、切割速度对射流作用的发挥和刀具力减小的影响进行了讨论,发现当射流位于刀具底部中心适当位置时,刀具力减少量最大。
The tests for the effects of jet position on drag bit cutting process were described. The influence of jet position on rock chips formed ahead of bit was analyzed. And the effects of cutting depth,bit velocity on bit force reductions were discussed. One of the most interesting results is that the water jet has the largest effect on drag bit forces when it is directed towards the center beneath drag bit.
