【摘要】：采用優(yōu)化設(shè)計(jì)技術(shù)進(jìn)行離心泵的設(shè)計(jì)為人們獲得性能優(yōu)良、運(yùn)行穩(wěn)定的離心泵的開辟了新途徑，優(yōu)化設(shè)計(jì)方法彌補(bǔ)了傳統(tǒng)設(shè)計(jì)方法的不足，代替大量的實(shí)驗(yàn)而節(jié)省很多人力物力;它在改善離心泵的水力性能和內(nèi)部流態(tài)以及達(dá)到增效節(jié)能的方面，，具有重要的實(shí)際意義。 本文主要針對(duì)離心泵的葉輪和壓出室這兩個(gè)重要部件進(jìn)行了優(yōu)化設(shè)計(jì)，具體做了以下工作： 1.首先用簡單的幾何分析與少量的數(shù)值計(jì)算相結(jié)合完成葉輪軸面投影圖的繪制，建立前后蓋板型線的數(shù)字模型。 2.然后分別運(yùn)用正交設(shè)計(jì)法和復(fù)合形法對(duì)已經(jīng)完成的數(shù)字模型進(jìn)行優(yōu)化設(shè)計(jì)，并比較這兩種方法的優(yōu)缺點(diǎn)。 3.其次對(duì)軸面流線分點(diǎn)的傳統(tǒng)方法進(jìn)行了改進(jìn)，運(yùn)用數(shù)值方法（二分法）實(shí)現(xiàn)對(duì)軸面流線的分點(diǎn)。 4.接著本文討論了離心泵蝸殼梯形截面渦室的一種新計(jì)算方法。 5.最后在Q35H50循環(huán)泵上進(jìn)行了試驗(yàn)并統(tǒng)計(jì)數(shù)據(jù)結(jié)果，以此驗(yàn)證以上這些優(yōu)化設(shè)計(jì)方法的可行性。
[Abstract]:The design of centrifugal pump with optimum design technology has opened up a new way for people to obtain the centrifugal pump with excellent performance and stable operation. The optimization design method makes up for the deficiency of the traditional design method. Instead of a large number of experiments to save a lot of manpower and material resources; It has important practical significance in improving hydraulic performance and internal flow state of centrifugal pump and achieving efficiency and energy saving. In this paper, the impeller and pressure-out chamber of centrifugal pump are designed optimally, and the following works are done: 1. Firstly, a simple geometric analysis and a few numerical calculations are used to complete the drawing of the impeller axial plane projection, and the digital model of the front and rear cover plate profile is established. 2. Then the orthogonal design method and the complex method are used to optimize the completed digital model, and the advantages and disadvantages of the two methods are compared. 3. Secondly, the traditional method of axial streamline separation is improved, and the numerical method (dichotomy) is used to realize the separation of axial streamline. 4. Then a new calculation method for trapezoidal vortex chamber of centrifugal pump volute is discussed. 5. Finally, the experiment on Q35H50 circulating pump is carried out and the statistical results are given to verify the feasibility of these optimization design methods.
