| 摘 要： | 本文计算和论述了回转冲击钻进中管道液流产生的水击及其影响。使用蓄能器可以改善管道液流动态、提高冲击器的工作能力、减少水击能量的损失。凡冲击器的基础频率越低,蓄能器的安装距离则越大,否则效果相反。从管道各部水压变化实测证明蓄能器确能减小管道压力波动幅值,提高冲击器频率。利用热力学原理可以计算蓄能器每次蓄释的能量。

| Abstract: | In this paper,the water hammer which takes place in flowing liquid as hydraulic percussion drill working has been calculated and studied. An air-bag energy reservoir has gained advantages for improving the condition of water flow and raising the frequency and force of hydraulic peccussion drill. The distance between energy reservoir and drill is an important factor which is determined by fundamental frequency of percussion drill. |
