driving nozzle 中文意思是什麼

driving nozzle 解釋
驅動噴嘴
  • driving : adj. 1. 推動的，起推動作用的。2. 【機械工程】傳動的；主動的。3. 猛沖的。4. 精力充沛的，有上進心的；（監工等對工人）苛刻的。5. 駕駛的，操縱的。
  • nozzle : n. 管嘴；噴嘴；〈俚語〉鼻子。 a jet [propelling] nozzle 【火箭】尾噴管。
  1. A reasonable position of driving nozzle helps to achieve the maximum material flow that also depends on other parameters such as backpressure, properties of conveyed material and driving gas. it is observed that, an increase of convergent section angle is harmful to the pneumatic conveying system, and also influences on the mass flow rate of conveyed material, the distribution of static pressures in injector and the pressure drops of conveying pipe. in addition, within a reasonable scope of air mass rate, increasing the driving jet velocity is more advantageous than enlarging the dimension of driving nozzle

    試驗研究發現，氣體噴嘴位置對氣固噴射器的輸送能力影響最大，氣體噴嘴存在某一最佳位置，而這一最佳位置與背壓、輸送物料特性和輸送風特性相關聯；氣固噴射器的收縮角對其輸送能力、內部靜壓分佈和輸送管阻力特性均有適量影響，收縮角增大對整個輸送系統均不利；在適當的輸送風范圍內，提高氣體噴嘴出口速度比擴大氣體噴嘴尺寸更為有利，但氣體噴嘴出口速度過高會增加氣固噴射器和輸送管內的能量損耗，給輸送帶來不利的影響；系統背壓與氣固噴射器的氣體噴嘴出口速度的選取有關。
  2. Through the controls of geometric dimension of micro - nozzle and driving frequency to obtain the volume of droplets in the grade of pico to femto litre, which is applicable to make high density micro - array

    通過微噴嘴幾何尺寸控制和驅動頻率控制獲得從飛升到皮升級樣點體積，可以用於製作高密度的微陣列。
