本文介绍采用循环夹瓦总成和循环带构成的泡沫保温层连续浇注成型机的结构原理,生产裸露泡沫保温管的过程和在泡沫保温管外包覆聚乙烯保护层的工艺及其技术经济效果.

Crack fatigue growth rate under longitudinal cyclic tension combined with horizontal bending loading has been experimentally studied with specially designed apparatus in this paper. A simple and safe method is presented for solving fatigue strength of this component. Then, a formula ofcrack fatigue growth rate, is presented for this case。The ratio between minimum and maximum tensile loads being considered, the formula becomes, which extended the formula presented by Forman for this situation.

利用了特制加载架,实验研究了在轴向交变拉伸与横向弯曲复合载荷作用下的裂纹疲劳扩展规律,提出对这类受载构件疲劳强度的简单且安全的处理力法。然后提出了在这种载荷作用下的裂纹疲劳扩展速率(da)/(dN)公式,即。在考虑拉伸载荷的比值时,建议用下式,即做为对Forman公式在该情况下的扩充。

By first analyzing the motion pattern of conventional beam-pumping units, this article sets up the motion index mx equation of the non-symmetric cyclic conventional beam-pumping units. Using the above mentioned result the improved design of rear-set equilibrium weight CYJ5-2.7 -26B type conventional beam-pumping unit can be made. By analyzing the angle of the installed power and the crankshaft torque of the gear box, the improved pumping unit has a reasonable structure and marked economic results.

本文从分析常规游梁抽油机的运动规律入手,建立了非对称循环常规抽油机的运动指标m_a方程,求极值后归纳出一元六次方程,求解得优化四连杆的比值;据平衡原理,可确定平衡重最佳后置角。应用上述结果,可作出“平衡重后置”CYJ5—2.7—26B型常规抽油机的改进设计。从装机功率和减速箱曲柄轴扭矩的角度来分析,改进后的抽油机结构合理,经济效果显著,在油田生产中有推广应用价值。
