摘要:
计算U型节流阀口过流截面通流面积A1(X)、A2(X)及其湿周Pw1Pw2,并得到了等效水力直径Dh1Dh2。推导了表征阀口节流特性的参数:节流压降分配系数均值E(k)及其方差D(k),空化指数σ2的均值E(σ2in)、E(σ2out)及其方差D(σ2in)、D(σ2out)。利用正交试验设计和模糊综合判断得到了节流阀口优化结构,并与初始节流阀口相比较。结果表明:Dh2提高了53.85%; E(k)与1的偏差减小了25.23%,D(k)降低了80.50%; D(σ2in)、E(σ2in)、D(σ2out)和E(σ2out)分别减小了35.16%、9.32%、1.61%和62.39%。
Abstract:
By calculating the areas of throttling sections in U-shape orifice and their wetted perimeters, the equivalent hydraulic diameters Dh1,Dh2 were obtained. Throttling performance parameters,such as mean E(σ2in),E(σ2out),variance D(σ2in),D(σ2out),mean E(k)and its variance D(k)were derived. Based on orthogonal experimental design and comprehensive fuzzy judgment method,hydraulic throttling orifice structure was obtained and compared with original date. Results showed that Dh2 increased 53.85%; the difference between E(k)and 1 decreased 25.23%,and D(k)decreased 80.50%; parameters D(σ2in),E(σ2in),D(σ2out)and E(σ2out)decreased 35.16%,9.32%,1.61%, and 62.39%,respectively.
