4-72C型碳鋼離心風(fēng)機(jī) 4-72C型碳鋼離心風(fēng)機(jī)可輸送空氣和其它不自燃的、對(duì)人體無(wú)害的、對(duì)鋼材無(wú)腐蝕性的氣體。氣體內(nèi)不允許有粘性物質(zhì)，所含塵土及硬質(zhì)顆粒物不大于150mg/m3。氣體溫度不得超過(guò)80℃該風(fēng)機(jī)廣泛適用于工礦企業(yè)、大型建筑物、賓館酒樓等室內(nèi)通風(fēng)換氣排煙。
產(chǎn)品型式:本公司號(hào)有NO2.8、3.2、3.6、4、4.5、5、5.6、6、6.3、7.1、8、10、12十三種?？芍瞥捎倚妥笮齼煞N型式，葉輪順時(shí)針旋轉(zhuǎn)，稱(chēng)為右旋風(fēng)機(jī)。以“右”表示，葉輪逆時(shí)針旋轉(zhuǎn)，稱(chēng)為左旋風(fēng)機(jī)，以“左”表示。風(fēng)機(jī)的出口位置，以機(jī)殼的出風(fēng)角度表示。4-72NO2.8-10出廠時(shí)均做成多種型式，可根據(jù)使用單位要求安裝成所需的位置，即出風(fēng)口位置調(diào)整范圍0°~225°間隔是22.5°或45°，即（0°、45°、90°、135°、180°、225°）共六種。NO7.1-10根據(jù)用戶(hù)需求制成一種方向角度。風(fēng)機(jī)的傳動(dòng)方式為C式。
結(jié)構(gòu)特點(diǎn):本風(fēng)機(jī)主要由葉輪、機(jī)殼、進(jìn)風(fēng)口、機(jī)架、軸承箱等皮帶傳動(dòng)而組成。葉輪：由10個(gè)后傾斜的機(jī)翼型葉片、曲線型前盤(pán)和平板后盤(pán)組成。并經(jīng)過(guò)動(dòng)平衡校正，氣動(dòng)性能，故運(yùn)轉(zhuǎn)平衡、振動(dòng)小、效率高、壽命長(zhǎng)等特點(diǎn)。機(jī)殼：用鋼板焊成蝸型殼體。進(jìn)風(fēng)口：制成整體（全部模具成型），裝于風(fēng)機(jī)的側(cè)面，于軸向平行的戴面未曲線形狀，能使氣體順利進(jìn)入葉輪，且損失較小。傳動(dòng)組：由主軸、軸承箱、聯(lián)軸器等。主軸由優(yōu)質(zhì)鋼制成，軸承箱整體結(jié)構(gòu)，采用滾動(dòng)軸承，分為水冷和油冷兩種。

4-72C Carbon steel centrifugal fan 4-72C Carbon steel centrifugal fan It can transport air and other non-flammable harmless to human body and non-corrosive gas to steel. No viscous substances are allowed in the gas and the dust and hard particles are not more than≤150mg/m3. The air temperature shall not exceed≤80℃. The fan is widely used for indoor ventilation and smoke extraction in industrial and mining enterprises large buildings hotels and restaurants.
Product type: The company has NO2.8、 3.2、 3.6、 4、 4.5、 5、 5.6、 6、 6.3、 7.1、 8、 10、 12 13kinds. Can be made into right-handed and left-handed two types the impeller rotating clockwise called right-handed fan. In & other; Right & throughout; That the impeller rotates counterclockwise called the left cyclone to “ Left & throughout; Said. The outlet position of the fan is expressed by the outlet Angle of the enclosure. 4-72NO2.8-10 are made into a variety of types when leaving the factory can be installed into the required position according to the requirements of the user that is the position of the air outlet adjustment range 0° ~ 225° Interval is 22.5° Or 45° That (0° And 45° And 90° And 135° And 180° And 225°) A total of six. No7.1-10 according to user requirements to make a direction Angle. The transmission mode of the fan is C type.
Structure features: The fan is mainly composed of impeller housing air intake frame bearing box and other belt drive. Impeller: consists of 10 rear sloped airfoil blades curved front disc and flat rear disc. And after dynamic balance correction pneumatic performance so the operation balance small vibration high efficiency long life and other characteristics. Housing: welded with steel plate into a cochlear housing. Air INLET: MADE INTO a WHOLE (all mold molding) installed on the side of the fan parallel to the axial surface without curve shape can make the gas smoothly into the impeller and the loss is small. Transmission group: spindle bearing box coupling etc. The main shaft is made of high quality steel. The overall structure of the bearing box is made of rolling bearings which are divided into water cooled and oil cooled.
