风机性能参数
风机的性能参数主要有流量、压力、功率,效率和转速。另外,噪声和振动的大小也是主要的风机设计指标。流量也称风量,以单位时间内流经风机的气体体积表示;压力也称风压,是指气体在风机内压力升高值,有静压、动压和全压之分;功率是指风机的输入功率,即轴功率。风机有效功率与轴功率之比称为效率。风机全压效率可达90%。
风机的未来
风机发展将进一步提高风机的气动效率、装置效率和使用效率,以降低电能消耗;用动叶可调的轴流风机代替大型离心风机;降低风机噪声;提高排烟、排尘风机叶轮和机壳的耐磨性;实现变转速调节和自动化调节。
鼓风机有两大类,ysdzxcvb201605211一类是叫“离心式鼓风机”,它的原理是由于风机工作时里面的风机叶轮高速旋转,使风机壳里的空气产生离心力而被甩离风机叶轮,经过出风口被“压送”出风机;而此时由于风机叶轮周围的空气被甩出而产生“负压”,所以“新空气”便从进风口处被源源不断地补充进来,构成了风机的正常工作状态;第二类是叫“轴流风机”,它的工作原理是:由于这种风机和电风扇一样,其叶片的面和风机轴是有一个夹角的,在旋转时,叶片把空气顺轴向往出风口“推”,而在进风口处就形成了一定的负压,新空气也就被补充进来,这样也就保持了正常工作的状态。
普通型轴流风机可用于一般工厂、仓库、办公室、住宅内等场所的通风换气,也可用于冷风机(空气冷却器)、蒸发器、冷凝器、喷雾降、等等,也有矿用轴流风机,
防腐、防爆型轴流风机采用防腐材料及防爆措施,并匹配防爆电机,可用于输送易爆、易挥发、具有腐蚀性的气体,
要求轴流风机输送的气体应无显著灰尘,无粘性和纤维物质;电动机直连型温度不超过40℃,皮带传动型温度不超过60℃。输送气体的粉尘量不得超过150mg/m3,
轴流风机主要由叶轮、机壳、电动机等零部件组成,支架采用型钢与机壳风筒连接。其中防腐型轴流风机叶轮、机壳均为玻璃钢制成,其它型式轴流风机一般采用钢板制成。
工作原理风机的叶轮由数十片叶片组成,它类似庞大的气轮机的叶轮。叶轮叶片中间的空气受到了离心力的作用,向叶轮的边缘运动,在那里空气进入泵体环行空腔,重新从叶片的起点以同样的方式再进行循环。叶轮旋转所产生的循环气流,
以极高的能量离开气泵以供使用。风机采用专用电机,结构紧凑,体积小,重量轻,噪音低,送出气源无水无油
当叶轮旋转时,气体从进风口轴向进入叶轮,受到叶轮上叶片的推挤而使气体的能量升高,然后流入导叶。导叶将偏转气流变为轴向流动,同时将气体导入扩压管,进一步将气体动能转换为压力能,最后引入工作管路。
轴流式风机叶片的工作方式与飞机的机翼类似。但是,后者是将升力向上作用于机翼上并支撑飞机的重量,而轴流式风机则固定位置并使空气移动。AFB0748HH 70 x 70 x 25.4 MM SERIES AFB AFB0712L AFB0724L AFB0712M AFB0724M AFB0712H AFB0724H AFB0712HH AFB0724HH AFB0712VH AFB0724VH AFB0712SH 80 x 80 x 15 MM SERIES AFB AFB0812LB AFB0824LB AFB08 AFB08 AFB0812HB AFB0824HB AFB0812HHB AFB0824HHB AFB0812VHB AFB0824VHB AFB0812SHB AFB0824SHB 80 x 80 x 20 MM SERIES AFB0812LD AFB0824LD AFB0812MD AFB0824MD AFB0812HD AFB0824HD AFB0812HHD AFB0824HHD AFB0812VHD AFB0824VHD AFB0812SHD AFB0824SHD 80 x 80 x 25.4 MM SERIES AFB AFB0805L AFB0812L AFB0824L AFB0848L AFB0805M AFB0812M AFB0824M AFB0848M AFB0805H AFB0812H AFB0824H AFB0848H AFB0812HH AFB0824HH AFB0848HH AFB0812VH AFB0824VH AFB0812SH AFB0824SH 92 x 92 x 15 MM SERIES AFB AFB0912LB AFB0912MB AFB0912HB AFB0912HHB 92 x 92 x 20 MM SERIES AFB AFB0912LD AFB0924LD AFB0912MD AFB0924MD AFB0912HD AFB0924HD AFB0912HHD AFB0924HHD AFB0912VHD AFB0924VHD 92 x 92 x 25.4 MM SERIES AFB AFB0912L AFB0924L AFB0948L AFB0912M AFB0924M AFB0948M AFB0912H AFB0924H AFB0948H AFB0912HH AFB0924HH AFB0948HH AFB0912VH AFB0924VH 120 x 120 x 25.4 MM SERIES AFB1212L AFB1224L AFB1212M AFB1224M AFB1212H AFB1224H AFB1212HH AFB1224HH AFB1212VH AFB1224VH AFB1212SH AFB1224SH 120 x 120 x 38 MM SERIES AFB AFB1212LE AFB1224LE AFB1248LE AFB1212ME AFB1224ME AFB1248ME AFB1212HE AFB1224HE AFB1248HE AFB1212HHE AFB1224HHE AFB1248HHE AFB1212VHE AFB1224VHE AFB1248VHE AFB1212SHE AFB1224SHE 172 X 150 X 25.4 MM SERIES AFB AFB1512L AFB1512M AFB1512H AFB1524L 172 X 25.4 MM SERIES AFB AFB1712L AFB1712M AFB1712H AFB1724L PART NO.
