【摘要】 利用Pro/E的热力学分析对机械密封的动环进行有限元分析,通过对密封环摩擦热、搅拌热等因素的分析计算,分析密封环端面温度对密封环结构变形的影响。结果表明:内流式机械密封端面温度径向呈近似抛物线分布;密封环内的温度梯度使密封环产生热变形,导致形成圆锥型的端面;热变形会使密封环产生内应力。更多还原

【Abstract】 The finite element analysis of movable ring in mechanical seal was performed by Pro/E thermodynamic analysis module.Through analysis and computation on the factors of seal ring such as the friction heat and agitation heat,the effect of the seal ring’s end surface temperature on the structure distortion of the seal ring was analyzed.Result shows that the end surface temperature of the internal flowing mechanical seal is approximate parabola distribution;the temperature gradient in the seal ring makes the seal ring thermal deformation,which results in conoid end surface;thermal deformation can result in the inner stress on the seal ring.更多还原
