firing point

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,便于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。

Through the special studies on impacts to atomizing and humidifying effect from such factors as the firing pin type , centrifugal structure , higher spraying pressure , less aperture , initial water temperature and original state of the air , some conclusions are obtained , such as : the centrifugal nozzle with firing pin type , high pressure and little aperture has bigger air eddy and atomizing angle . the spaying liquid has high velocity . the droplet is small , and the heat and mass transfer velocity is high 通過對撞針型結構、離心式結構、較高的噴水壓力、較小的噴嘴孔徑、噴水初溫及待加濕空氣初狀態對霧化加濕效果的作用原理的重點分析,得到:撞針型高壓小孔徑離心式噴嘴具有較大的空氣渦與霧化角,噴出的液體流速高、液滴小、水與空氣傳熱傳質速率高,撞針型結構提高了霧化加濕效率,高壓小孔徑的特點為霧化加濕提供了較大的能量,而噴水初溫的升高會減小水的粘性力和表面張力,從而優化加濕效果。

Based on the theory analysis and experiment work , the paper studies the humidifying property of the centrifugal nozzle with firing pin type , high pressure and little aperture . compared with the traditional air washer , the high efficiency and energy saving character of this kind of nozzle is stood out 課題從理論和試驗兩方面分析研究了撞針型高壓小孔徑離心式噴嘴的霧化加濕性能,并將其與傳統噴水室加濕系統進行能耗比較,突出了撞針型高壓小孔徑離心式噴嘴高效節能的特點。

As to the work about theory analysis , at first , the paper describes the atomizing and humidifying process of the centrifugal nozzle with firing pin type , high pressure and little aperture and liquid physical properties . later , combining with the structure characters of this kind of nozzle , the paper studies on the theory of the atomizing and humidifying process by three phases , which is water film forming phase , water film falling into pieces phase , and heat and mass transfer between water and air phase in turn 理論工作方面,首先描述了撞針型高壓小孔徑離心式噴嘴的霧化加濕過程和液體的物理性質,然后結合撞針型高壓小孔徑離心式噴嘴的結構特點,將其霧化加濕過程分三個階段進行機理上的研究,這三個階段依次為液膜形成、液膜初次破碎及二次霧化、水與空氣的熱濕交換。

Special gun muzzle , rough nail hardened design , powerful explosive force , low recoil , most important super version series , firing pin under special treatment , various design , made as per the principle of car suspension , above 5 folds more durable than common nail gun 槍咀特制,粗牙加硬設計,爆發力強,后坐力低,最主要超級版系列,撞針是經過特別處理,一頭大小設計,汽車避震原理制造,比普通牙釘槍耐用5倍以上。

However , the related research is rarely reported on the humidifying property of the centrifugal nozzle with firing pin type , high pressure and little aperture 但當前對該類型噴嘴加濕性能的相關研究還較少見諸報道。

This “ paper mainly researches on the humidifying property of the centrifugal nozzle with firing pin type , high pressure and little aperture 課題主要對撞針型高壓小孔徑離心式噴嘴的霧化加濕性能進行研究。
