摘要
FIS2200型钻井泵是为适应深井超深井钻井作业的需要而研制和开发的,液缸的承压能力和可靠性是确定泵设计参数和工作寿命的决定性因素。采用Pro／E、ANSYS等软件建立了FIS2200型钻井泵液缸的三维有限元分析模型,计算了其动、静强度和动态特性,获得了液缸在额定载荷作用下应力云图、动应力响应以及最大变形位置和变形量。计算结果表明,FIS2200型钻井泵液缸的动态性能良好,而且其结构动、静强度和疲劳极限足够,可以减小液缸外形尺寸．以减轻液缸的质量。
To meet the needs of drilling deep well or ultra-deep well, a Model FIS2200 Drilling Pump is developed. Reliability and pressure endurance of its hydraulic cylinder are determinants of parameter-choosing and service life. In this paper, 3D finite element model is established in Pro/E and ANSYS, static and dynamic performances are analyzed. Meanwhile, maximum deformation, stress distribution and dynamic stress response of the hydraulic cylinder are obtained under rated load. Computational results show that Model FIS2200 mud pump has good dynamic performance, enough structural dynamic and static strength and fatigue limits, which is helpful to reduce liner size and weight.
