詳細介紹

用途(USAGE)

BE射流(誘導)風機是專為公路、鐵路隧道縱向通風換氣系統(tǒng),并在緊急狀態(tài)下進行煙霧排放控制而設計的動力機械換氣設備。同時亦可用于類似隧道、輔助隧道工程場合的通風換氣,適用于海拔高度3500米以內工作運行要求。

BE射流(誘導)風機/軸流式消防排煙風機工作條件可在-25℃~50℃環(huán)境下連續(xù)工作運行,隧道內發(fā)生火災時,可允許在250℃下短時間運行(不超過1h)。

BE jet blower is a mechanical power designed for the vertical ventilation system in railways and highways and can control the smog at emergency time. it can also be applied to the ventilation system of some projects similar to tunnels and side-tunnels.The highest elevation where it can normally operste is at an elevation of 3500 meters high.

BE jet (induction) fan / axial flow fire smoke exhaust fan can operate continuously at- 25 ℃ ~ 50 ℃. In case of fire in the tunnel, it can operate for a short time at 250 ℃ (no more than 1h).


原理(Principle)

BE射流(誘導)風機葉輪葉片采用選的航空動力學原理而設計,經電動機帶動其旋轉對空氣作功,(在設計規(guī)定的幾何參數(shù)下)能產生最大的推力,將氣流經出氣段高速射出,并帶動其周圍的空氣一起向前流動。當空氣流動到接近滯止狀態(tài)時,又經下一組風機工作,來達到新空氣不斷地補充,排礎污濁的空氣,實現(xiàn)隧道內新鮮潔凈的空氣循環(huán)流動。

The impeller and blade of BE Series Jet Blower is designed by adopting advanced aerial dynamic principles.it is motivated by an electronic montor to rotate and exert work to the air.Under the geometric parameter it's design permites,it can produce the strongest thrust power to jet ut the air through the air let-out passage at high speed and to drive the surrounding air to flow forward together.When the flow of air approaches stagnation,the following blower group will continue to work so as to supply fresh air and let out filthy air- continuously.Therefore,the circulation of fresh and clean air in the tunnel will be .


結構(Structureee)

BE射流(誘導)風機由三段組成

BE jet blower is compossed of the following three sections

1進氣消聲段:(集風器、防護網、導流器、整流柵、消聲器)
