Application運(yùn)用：

這種風(fēng)機(jī)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(jī)。因?yàn)檫@種風(fēng)機(jī)無蝸殼設(shè)計(jì)，在裝入箱體內(nèi)后，Grade FE可以在可能空調(diào)箱內(nèi)實(shí)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(jī)直連設(shè)計(jì)，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(chǎng)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(diǎn)：

1.風(fēng)機(jī)葉片為高效低噪音機(jī)翼型設(shè)計(jì)，該葉片利用現(xiàn)今先進(jìn)的流體力學(xué)計(jì)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(chǎng)，通過不斷改變?nèi)~片角度，形狀，弧度等參數(shù)設(shè)計(jì)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(jī)葉片，前盤及中盤材質(zhì)為高強(qiáng)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(yùn)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(jī)進(jìn)口喇叭口采用的是類似風(fēng)機(jī)發(fā)動(dòng)機(jī)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(jī)的框架結(jié)構(gòu)鋼板焊接設(shè)計(jì)，擁有更高的結(jié)構(gòu)強(qiáng)度。同時(shí)，先進(jìn)的靜電粉末噴涂，可以保證在高溫高濕情況下長(zhǎng)時(shí)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(jī)可以設(shè)計(jì)為皮帶傳動(dòng)或直聯(lián)傳動(dòng)，風(fēng)機(jī)的軸承設(shè)計(jì)壽命為L(zhǎng)（10）=100000小時(shí)，風(fēng)機(jī)軸承在出廠前將會(huì)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(tái)風(fēng)機(jī)的葉輪都經(jīng)過動(dòng)平衡測(cè)試，當(dāng)風(fēng)機(jī)組裝完后，每臺(tái)風(fēng)機(jī)都進(jìn)行震動(dòng)測(cè)試，保證風(fēng)機(jī)能達(dá)到G2.5國(guó)際震動(dòng)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(jī)擁有在低頻段相對(duì)較低的噪音，使其整體噪音降低，同時(shí)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.
