| 摘 要： | 推导出了XXJ300/500液压蓄能修井机下放管柱刹车时,管路中液压冲击最大压力升高值的计算公式。通过仿真分析计算表明,下放管柱时,在管柱接近行程终点时减小节流阀开口面积,可以减小管柱到达行程终点时的末速度,从而可减小液压冲击。

| Abstract: | The formula of the greatest pressure value produced by hydraulic shock during braking of XXJ300/500 hydraulic energy-storing workover rig lowering pipestring is derived. The simulation analysis shows that decreasing throttle valve path area near the end of pipestring stroke can decrease the final velocity of pipestring, so that it can decrease hydraulic shock. |
