    然後,在中心系統內利用試驗設計理論安排訓練樣本,採用神經網路建立葉輪性能與子午流道設計參數之間的響應關系,同時計及葉片形狀對葉輪性能的影響,對子午流道及葉片進行優化。
  4. The main object of this paper is to design a diagonal impeller, which requires small size and high rotating speed. the first step of the design is to solve the radial equilibrium equations on the s2 stream surface. second, the blades designed according to the results of the first step

    方案計算是為二維設計做基礎;二維設計是在s2流面內用流線曲率法求解完全徑向平衡方程,利用流場計算的結果來初步判斷設計的工程合理性;葉片造型利用s2流場的計算結果,近似沿著氣流流面進行造型。
  5. The main object of this paper is to design a diagonal impeller, which requires small size and high rotating speed the first step of design is to solve the radial distribution of parameters at the inlet and outlet of the blade, such as pressure, temperature and velocity. and then, according to the radial distribution, we can design the diagonal impeller blade. blade elements are defined on a cone, which pass through the blade edge streamline location

    其設計思想是採用準三維設計方法,先進行二維流場計算,在葉片軸向間隙中設立計算站,應用數值計算方法計算葉片前後緣的壓力、溫度、速度等參數沿葉高的分佈,然後根據這些參數,選取若干個回轉面進行葉型設計;再將各回轉面上得到的基元葉型沿某一個積疊軸積疊起來形成三維葉片,最後對得到的三維葉片進行試驗,並對實驗結果進行分析比較。
  6. Main working principal is that the bottom scraper with low rotate speed impels materials to form circumfluence in the basin of machine, the impeller of rotor rotating with medium speed can not only add wallop to sand, but also can add shear force to the sand with scraper so that the sand can touch and scrub each other fast ; wind blasting is set to cool the hot sand, remove dust and strip the membrane so that fast speed of regeneration and top - grade used sand can be gained

    主要工作原理是低速轉動的底刮板推動物料在機盆內形成環流,中速轉動的轉子葉片既對砂子施以沖擊力,又與刮板配合對砂子施以剪切力,使砂粒間快速接觸和強烈摩擦,圍圈設風帶鼓風使熱砂沸騰冷卻除塵脫膜,從而達到再生速度快,回用砂質量好的目的。
