詳細(xì)介紹

用途(USAGE)

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

BE射流(誘導(dǎo))風(fēng)機/軸流式消防排煙風(fēng)機工作條件可在-25℃~50℃環(huán)境下連續(xù)工作運行,隧道內(nèi)發(fā)生火災(zāi)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(dǎo))風(fēng)機葉輪葉片采用選的航空動力學(xué)原理而設(shè)計,經(jīng)電動機帶動其旋轉(zhuǎn)對空氣作功,(在設(shè)計規(guī)定的幾何參數(shù)下)能產(chǎn)生最大的推力,將氣流經(jīng)出氣段高速射出,并帶動其周圍的空氣一起向前流動。當(dāng)空氣流動到接近滯止?fàn)顟B(tài)時,又經(jīng)下一組風(fēng)機工作,來達(dá)到新空氣不斷地補充,排礎(chǔ)污濁的空氣,實現(xiàn)隧道內(nèi)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(jié)構(gòu)(Structureee)

BE射流(誘導(dǎo))風(fēng)機由三段組成

BE jet blower is compossed of the following three sections

1進(jìn)氣消聲段:(集風(fēng)器、防護(hù)網(wǎng)、導(dǎo)流器、整流柵、消聲器)

Air let-in and muffing section:(air collector,protective net ,diversion set,rectification grid and muffler

2風(fēng)機段:機殼部、葉輪(動葉)部、靜葉(導(dǎo)葉)部、電動機

Blower section:casing part,impeller(moving blade)part,still blade(guide blade)part and electric motor

3出氣消聲段:(出氣消聲器)

Air let-out and muffing section:(air let-out muffler)
