超聲波霧化噴嘴又稱干霧抑塵噴嘴,能夠準(zhǔn)確有效的控制粉塵現(xiàn)場,擁有內(nèi)部混合設(shè)計JCO噴嘴和外部混合設(shè)計JAU的噴嘴。對于特定的流量,我們可以提供特殊定制,滿足您的要求。流量0.15 J至25 JN的型號。 空氣霧化噴嘴能夠比同類型的噴嘴節(jié)約50%至60%的資源,我們的雙流體噴嘴和超聲波霧化噴嘴的獨特之處在于,噴嘴具有氣壓可調(diào)節(jié)比例20:1,和霧滴大小減少調(diào)制能力.
Ultrasonic atomization nozzle is also called dry fog dust suppression nozzle,超聲波干霧噴嘴, can effectively cool the accurate dust in the scene, with external and internal mixing design JCO nozzle mix design JAU nozzle.For a specific flow, we can provide special customization, meet your requirements.Flow of 0.15 J to 25 Jacqueline Nottingham models.Air atomizing nozzle can be better than the same type of nozzle se 50% to 60% of the resources, our twin fluid nozzle, and ultrasonic atomizing nozzle is unique in that the nozzle with pressure adjustable ratio systematically, and the droplets size reducing modulation ability.

超聲波霧化噴嘴試驗結(jié)果和分析超聲波噴嘴典型頻譜圖超聲波噴嘴頻譜圖如圖2所示從圖中可知,在頻率處出現(xiàn)峰值,其幅值分別為聲壓出現(xiàn)無規(guī)律變化,有些測試位置上聲壓突然變大,這是由于在這些位置上脈動頻率和共振腔的固有頻率相同產(chǎn)生共振,聲壓出現(xiàn)極大值。?從頻譜圖可以看出,干霧噴嘴,在其他條件給定的情況下在一定范圍內(nèi)變化時聲
壓才會出現(xiàn)峰值,而超出這一范圍就沒有明顯的峰值。這是由于共振區(qū)內(nèi)的超聲波是由入射波和經(jīng)過共振腔的反射波疊加而成的
,如果入射波和反射波正好相反,那么就不能形成共振峰值。如果的距離太短頻率增加噴口和共振腔狹縫對外射流共振腔失去作用。如果的距離太由于噴口和共振腔距離太遠(yuǎn)而使到達(dá)共振腔的聲能太少形成共振頻率的振幅很小給其它噴注噪聲所
覆蓋看不到明顯的峰值。只有當(dāng)間距滿足入射波和反射波疊加的條件并且噴口和共振腔距離處于佳值,才使共振峰值達(dá)到很大
即聲壓達(dá)到很大。?顯然聲壓越大霧化效果就越好,對振動頻率的選,一般在10kHz左右較好,干霧抑塵噴嘴,若頻率太低,干霧噴嘴,不易起振,若頻率太高,聲能輸出受限制,因此既不能只強(qiáng)調(diào)頻率而忽視聲壓,也不能只強(qiáng)調(diào)聲壓而忽視頻率要兩者兼顧。
