The strength analysis of mud pump key parts based on finite element method

研究泥浆泵关键零部件的应力分布,并根据分析结果验证其是否满足相应的工况要求,以提高泥浆泵的功率等级。对1600HP泥浆泵的曲轴、连杆、齿轮轴分别基于1800HP型泥浆泵的最大工况受力条件下进行有限元分析,找出应力分布情况,并校验各主要零部件的强度。经过分析后,发现1600HP各关键零部件设计强度富余,完全满足1800HP的工况要求,为泥浆泵的功率提升提供理论支撑。

Studing the stress distribution of mud pump key parts, and according to the anslysis results show it satisfies the requirement of working condition,in order to improve the power of the mud pump. The three - dimensional finite dement method was adopted to analyses the stress and strain on 1600HP mud pump key parts ,based on the 1800HP mud pump maximum load conditions. After analysis, found the 1600 HP key parts and components design strength to spare, fully meet the requirement of the operation condition of the 1800 HP,and provide the oretical support for mud pump power in- creases.
