Research on the damage of four chamber reverse osmosis diaphragm
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.
