【摘要】：Q25H52電液循環(huán)泵是一種新型高速離心泵,主要用于特種動(dòng)力裝備,本課題關(guān)于Q25H52電液循環(huán)泵的研究主要包括葉輪的繪形、繪型結(jié)果的優(yōu)化和性能測(cè)試三部分: 1.葉輪的繪形 葉輪是影響離心泵性能的主要零件,離心泵葉輪的繪形即繪制出葉輪的前后蓋板該和葉片的型線,繪型的好壞直接關(guān)系設(shè)產(chǎn)品的性能,是葉輪設(shè)計(jì)中最關(guān)鍵的步驟。本文提出了一種新的軸面軸面投影圖的繪制方法。先對(duì)葉輪進(jìn)行簡(jiǎn)單的幾何分析,確定葉輪前蓋板由一條直線和兩條弧線構(gòu)成,后蓋板由一條直線和一條弧線構(gòu)成,之后對(duì)型線進(jìn)行少量的數(shù)值計(jì)算,將每個(gè)參數(shù)用方程式表達(dá)出來(lái),最后使用matlab對(duì)計(jì)算編程,使葉輪的繪型可以通過(guò)輸入一組參數(shù)由電腦計(jì)算完成,之后修改也只用改變相應(yīng)參數(shù)即可,大大簡(jiǎn)化了計(jì)算量。所得結(jié)果精度極高,接近理論設(shè)計(jì)的形狀。在葉輪流線的分點(diǎn)計(jì)算時(shí),本文將“二分法”引入,編程進(jìn)行計(jì)算,結(jié)果表明計(jì)算簡(jiǎn)便,分點(diǎn)精度高。 2.優(yōu)化設(shè)計(jì) 葉輪設(shè)計(jì)完成后,需對(duì)葉輪進(jìn)行優(yōu)化設(shè)計(jì),葉輪的優(yōu)化設(shè)計(jì)可以改善葉輪形狀,顯著提高葉輪效率,是葉輪設(shè)計(jì)的必須步驟。本論文選取正交優(yōu)化法。所謂正交設(shè)計(jì),就是利用事先制好的特殊表格—正交表來(lái)科學(xué)地安排試驗(yàn),并進(jìn)行試驗(yàn)數(shù)據(jù)分析的一種方法。本文采用L1 6( 45)最后表對(duì)繪型結(jié)果進(jìn)行了兩輪優(yōu)化,經(jīng)檢驗(yàn)優(yōu)化后的結(jié)果接近于理論結(jié)果,故優(yōu)化效果很好。 3.性能測(cè)試 完成葉輪設(shè)計(jì)后進(jìn)行了Q25H52電液循環(huán)泵的性能測(cè)試,檢驗(yàn)了在不同流量、轉(zhuǎn)速以及通氣情況下的工作情況,測(cè)試結(jié)果表明Q25H52電液循環(huán)泵工作穩(wěn)定高效,符合設(shè)計(jì)要求。
[Abstract]:Q25H52 electro-hydraulic circulating pump is a new type of high-speed centrifugal pump, which is mainly used for special power equipment. The research on Q25H52 electro-hydraulic circulating pump mainly includes the drawing of impeller. The optimization and performance testing of the drawing results are three parts: 1. Shape of impeller Impeller is the main part that affects the performance of centrifugal pump. The drawing of centrifugal pump impeller is the drawing of the front and rear cover plate of impeller and the profile of blade. It is the most important step in impeller design. In this paper, a new method of drawing axial plane projection map is put forward. Firstly, a simple geometric analysis of impeller is carried out, and it is determined that the front cover plate of impeller is composed of a straight line and two arcs. The back cover plate is composed of a straight line and an arc. Then a small amount of numerical calculation is carried out on the shape line. Each parameter is expressed by equation. Finally, the matlab pair is used to program the calculation. The drawing of impeller can be completed by computer by inputting a set of parameters, and then modified only by changing the corresponding parameters, which greatly simplifies the calculation. The result is extremely accurate. This paper introduces the dichotomy method into the calculation of the separation point of the impeller streamline line and carries out the calculation by programming. The results show that the calculation is simple and the accuracy of the separation point is high. 2. Optimal design After the design of impeller is finished, the impeller should be optimized. The optimal design of impeller can improve the shape of impeller and improve the efficiency of impeller. Orthogonal design is a necessary step in the design of impeller. In this paper, orthogonal optimization method is chosen. The so-called orthogonal design is the use of a special form made in advance-orthogonal table to scientifically arrange the test. A method to analyze the experimental data is presented in this paper. 45) at the end of the paper, two rounds of optimization are carried out, and the results are close to the theoretical results, so the optimization effect is very good. 3. Performance testing After the impeller design was completed, the performance of Q25H52 electro-hydraulic circulating pump was tested, and the working conditions of Q25H52 electrohydraulic circulating pump under different flow rate, rotating speed and ventilation were tested. The test results show that the Q 25 H 52 electrohydraulic circulating pump works stably and efficiently and meets the design requirements.
