摘要
通过价值工程(Value Engineering,VE)的分析方法,对既有膜组件中除纤维外的各主要零件的价值系数进行分析.通过分析发现,现有组件中罗筒、顶头和密封胶的价值系数>1,应该加大投入力度;而筒体、不锈钢卡箍的价值系数<1,可以降低其投入成本.结合现有组件在使用中的问题提出了针对饮用水处理用膜组件的修改建议,并进行了后续验证,通过中试证明了前期价值工程分析的合理性.
The functions of major parts of original UF module except membrane fiber have been analyzed by value engineering. The analysis revealed that the value coefficients of the parts of body, end enclosure and sealant were larger than one, so that these parts should be increased investment. Whereas the value coeffi- cients of shell and stainless steel hoop were less than one, so they should be decreased investment. To solve the problems encountered by original UF module using for drink water during operation, the module revision was made based on the value analysis and the modified module was used for pilot application. The satisfactory result proved the value engineering a highly competent method.
