鋁制機翼型葉片無蝸殼風(fēng)機

Application運用：

這種風(fēng)機是專門為空調(diào)箱內(nèi)作送排風(fēng)使用，或可以做成箱體式風(fēng)機。因為這種風(fēng)機無蝸殼設(shè)計，在裝入箱體內(nèi)后，Grade FE可以在可能空調(diào)箱內(nèi)實現(xiàn)97%高效率的層流，從而可以使得換熱器的換熱效率大 大提高。由于這種風(fēng)機直連設(shè)計，所以也被廣泛用于醫(yī)院，半導(dǎo)體，太陽能等需要高靜壓，低噪音及高效率無塵的工業(yè)及民用場所。
This kinds of fan is mainly desigened for suppy and return air in air handing unit and cabinet fan. Since this is non-housing, after installed in the AHU, it will get an unltra smooth laminar flow effciency up to 97%, then to improve the beat exchange effciency grately. And also ilso direct drive design, it can be used in the Clean room of Hospital, semi-conductor industrial, solar industrial where higher pressure low sound and high effciency non-dust needed.
 

FEATURE特點：

1.風(fēng)機葉片為高效低噪音機翼型設(shè)計，該葉片利用現(xiàn)今先進(jìn)的流體力學(xué)計算軟件（CFD）及有限元分析軟件相互配合，模擬旋轉(zhuǎn)葉輪內(nèi)部三維流場，通過不斷改變?nèi)~片角度，形狀，弧度等參數(shù)設(shè)計出來的阻力和紊流度小的葉片及葉輪。
The fan blade is airoil shaped with quiet and high efficiency aharacteristic. The blade is designed with CFD and FEM software. We ues the software Simulation the three-dimensional fluid flow inner the wheel by continuously change the shape and angle to get a correct wheel shape with low energy loosing at last
2.風(fēng)機葉片，前盤及中盤材質(zhì)為高強度鋁鎂合金焊接制造，轉(zhuǎn)速可達(dá)3000轉(zhuǎn)，耐壓可達(dá)3000PA以上。由于是鋁鎂合金材料，它本身具有很好的防腐性能，在潮濕及中溫情況下保持持久穩(wěn)定運行。
The wheel blade, bacl and front plate are ail welded together with Aluminum-magnesium alloy material. The max running speed of the wheel is 3000RPM, and this kind of fan can reach 3000Pa external stantistic pressure. Since the corrosion resistance characteristic, the fan can be used in a circumstance with high density of moisture.
3.風(fēng)機進(jìn)口喇叭口采用的是類似風(fēng)機發(fā)動機進(jìn)口口旋壓拉伸加工工藝，直接得到剖面為文丘里型線的雙曲面進(jìn)風(fēng)口，保證了氣流通過喇叭口平順沒有紊流地進(jìn)入葉輪，消除進(jìn)風(fēng)損失，提高效率。
Fan inlet cone is produced by large automatic spun machine with one piece large material. The section of the inlet cone is a double curve of Venturi-type, this inlet cone shape will minimize the fan inlet turbulence, increase the whole fan efficiency. .
4.風(fēng)機的框架結(jié)構(gòu)鋼板焊接設(shè)計，擁有更高的結(jié)構(gòu)強度。同時，先進(jìn)的靜電粉末噴涂，可以保證在高溫高濕情況下長時間防腐。
Laser cut and precision formed panels with all welded construction offer the highest rigidity, Electrostatically applied, thermosetting polyester urethane powder paint provides a clean and uniform coating that will not chip off if the unit is bumped or dented.
5.風(fēng)機可以設(shè)計為皮帶傳動或直聯(lián)傳動，風(fēng)機的軸承設(shè)計壽命為L（10）=100000小時，風(fēng)機軸承在出廠前將會被注滿油脂。
The fan can be designed as direct drive or belt drive, The bearing is Customer-oriented designing, the at least bearing life is L（10）=100000, every bearing will be oil filled before it leave the fanctory.
6.每臺風(fēng)機的葉輪都經(jīng)過動平衡測試，當(dāng)風(fēng)機組裝完后，每臺風(fēng)機都進(jìn)行震動測試，保證風(fēng)機能達(dá)到G2.5國際震動限值標(biāo)準(zhǔn)。
Every fan wheel will be blanced with dynamic balancing machine, after the whole fan assembled. Every fan will be applied viberation test, The maximum allowable fan vibration shall meet balance quality grade G2.5 standards Report shall be provided at no charge to the customer upon request.
7.在低頻段的高音將很難被消除，但該款12葉片的無渦殼風(fēng)機擁有在低頻段相對較低的噪音，使其整體噪音降低，同時也易于消音。
High sound power levels in the first and second octave bands are difficult to attenuate. The 12 bladed wheel generates less low frequency sound power.
