汽轮机快速冷却有蒸汽顺流和逆流冷却、压缩空气顺流和逆流冷却、抽真空吸入环境空气顺流和逆流冷却等 ;另外 ,还有鼓风逆流快冷和压缩空气汽缸导入快冷等的几种方式。为了评价上述快速冷却方式的优缺点 ,应用模糊数学的处理方法 ,提出了评价快速冷却方式的综合指标 ,指标综合考虑了影响快速冷却方式总体性能的程度 ,通过计算隶属函数并考虑各指标在快速冷却方式中的重要程度 ,经过模糊变换得到每一种冷却方式的综合优劣度
Turbine rapid cooling with steam downstream and countercurrent cooling, compressed air downstream and countercurrent cooling, vacuum suction into the ambient air downstream and countercurrent cooling, etc .; In addition, the blast countercurrent fast cooling and compressed air into the cylinder and so fast Kind of way. In order to evaluate the merits and demerits of the rapid cooling method above, a comprehensive index to evaluate the rapid cooling method is put forward by applying the fuzzy mathematics processing method. The index comprehensively considers the degree of affecting the overall performance of the rapid cooling method. By calculating the membership function and considering the rapidity of each index, The degree of importance of the cooling method, after the fuzzy transform to get the overall advantages and disadvantages of each cooling method
