摘要
反渗透隔膜在净水机中起着至关重要的作用,但是存在容易破损的问题.因此,采用ANSYS有限元分析方法,对四腔体隔膜在不同工况下的应力分布进行研究,分析隔膜发生破裂的原因.根据有限元分析数据,发现最大应变和应力发生在支撑架上的液体出口处,与隔膜接触的水的表面的应变和应力均匀分布在扇形 45°轴线两侧.通过实验验证,发现隔膜容易发生破裂位置是腔体的最外缘处,结果与有限元分析结果吻合较好.
Abstract
Reverse osmosis membranes play a crucial role in water purifiers,but they are prone to damage.Therefore,ANSYS finite element analysis method to study the stress distribution of four chamber diaphragm under different working conditions and analyze the reasons for diaphragm rupture.According to the finite element analysis data,it was found that the maximum strain and stress occurred at the liquid outlet on the support frame,and the strain and stress on the surface of the water in contact with the diaphragm were uniformly distributed on both sides of the fan-shaped 45° axis.Through experimental verification,it was found that the diaphragm was prone to rupture at the outermost edge of the cavity,which was consistent with the results of finite element analysis.
