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。
