摘要
为更好地满足千米钻机孔底动力定向钻进的需求,研制了BWY-200/9型泥浆泵。对泥浆泵的关键部件曲轴进行动力学分析,得到一个工作循环中曲轴的受力危险区域,并采用有限元分析软件对这些危险区域进行静力学及疲劳强度分析,得到曲轴的应力应变分布云图,为BWY-200/9泥浆泵优化设计提供了理论依据。最后用试验结果证明泥浆泵的工作能力及主要部件曲轴的结构设计是合理、安全可靠的。
In view of the requirement for directional drilling of kilometer rig in the bottom of hole,it develops BWY-200/9 mud pump.It introduces the dynamic analysis of crankshaft and key component of the mud pump,obtains dangerous stress area in a working cycle.Based on finite element analysis software it analyzes the static and fatigue strength of these dangerous areas,reveals the contour of stress and strain,provides a theoretical basis for the optimal design of BWY-200/9 mud pump.The experiment shows that the working capacity of mud pump is well and crankshaft structure design are reasonable,safe and reliable.
