Integrated the work on theory and experiment, the paper provides technical performance material at large about the automating and humidifying character of the centrifugal nozzle with firing pin type, high pressure and little aperture to the manufacture and user. with the valuable reference during the selecting the equipment and ascertaining the parameters, the users could select and control the humid parameter
課題的理論與試驗兩方面工作相結合，為撞針型高壓小孔徑離心式噴嘴的霧化加濕性能提供了較為詳細的技術性能資料，為生產廠家和用戶在設備選型和參數選擇過程中，提供了有價值的參考，便於用戶正確而經濟地選擇、控制濕度參數，有效調節噴嘴孔徑、噴水初溫和噴水壓力的大小。According to the experimental data of droplet size 、 particle spectrum range 、 droplet cone shape 、 flow rate 、 cover area and cover area rate which obtained through changing the pressure of power sprayer and the nozzle diameter in greenhouse ， this paper made comparative analysis on atomizing performance in same pressure and different nozzle type between same nozzle type and different pressure. the conclusion is that : the ejection rate and the droplet cone shape change with the variation of pressure and nozzle diameter ， average particle diameter decreases obviously and particle quantity increases obviously with the increase of pressure and decrease of nozzle diameter. these results will lay experimental foundation for precise spraying 、 low pollution and highly effective operation
本文根據溫室內動力噴霧機壓力與噴嘴孔徑的變化影響霧滴大小、粒譜范圍、霧錐形狀、流量、覆蓋面積及覆蓋面積率的試驗數據，對相同壓力下不同噴嘴型號和相同噴嘴型號時壓力不同時的微粒化性能進行對比分析和研究，得到如下結論噴出量與霧錐形狀隨著壓力和噴嘴孔徑大小變化而變化；平均粒徑隨著壓力的增加和噴嘴孔徑的減小而明顯減小；粒數隨著壓力的增加和噴嘴孔徑的減小而明顯增多，為精噴量、低污染、高防效的防除作業奠定了實驗基礎。When the water - air ratio increases, air ' s changing quantity of enthalpy and absolute humid will be enhanced. at last, the paper analyses the data from single factor experiment by mathematics method and gets relationship formulas about the nozzle flux, valid humidifying quantity and air ' s enthalpy changing quantity
最後，對上述單因素試驗得到的數據進行數學分析，運用線性回歸分析、多項式回歸分析和非線性回歸分析的數學方法，得到影響撞針型高壓小孔徑離心式噴嘴的噴嘴流量、有效加濕量和空氣焙變量的數學關系式。This item successfully completed under scheduled. one hand, it breaks the customary practice of only using foreign numerical control system to equip with high precision machine, escapes the hard problem that it is difficult to self redevelop in limited time by using foreign numerical control system, and resolves the problems that it needs convenience in manipulation and high precision in grinding
一方面，打破了「高精度機床的數控裝置只選用國外數控系統」的慣例，避開了選用國外數控系統在短時間內難以二次開發的難題，解決了噴油嘴中孔座面加工中高精度的加工技術要求問題和方便操作問題。For small aperture ejection nozzle, especially to the p serial type that the center hole diameter is 4mm, its center hole and inner cone is always adopting imported numerical control machine to grind
對于小孔徑的噴油嘴，特別是直徑為4mm的p系列噴油嘴的中孔座面的磨削，一直採用進口的數控磨床加工。To the places of small reynolds numbers and high media viscosity, it is difficult to reach the demand that using orifice plate and nozzle, etc, to make the measurement. and the 1 / 4 orifice plate was specially designed for that
對于管道雷諾數很小或介質粘度高的場合，應用孔板或噴嘴等來測量很難達到要求，而這些裝置正是專為此而設計的。分享友人
