玻璃钢离心风机顾名思义是一种外壳用玻璃钢防腐蚀材料制造的离心风机，工作原理是当电机转动带动风机叶轮旋转时，叶轮中叶片之间的气体也跟着旋转，并在离心力的作用下甩出这些气体，气体流速增大，使气体在流动中把动能转换为静压能，然后随着流体的增压，使静压能又转换为速度能，通过排气口排出气体，而在叶轮中间形成了一定的负压，由于入口呈负压，使外界气体在大气压的作用下立即补入，在叶轮连续旋转作用下不断排出和补入气体，从而达到连续鼓风的目的。 同等功率下，风压和风量一般程反比。 同等功率下，风压高，风量就会相对低，而风量大，风压就会低些，这样才能充分利用电机的功效率。
FRP centrifugal fan, as its name implies, is a kind of centrifugal fan made of FRP anti-corrosion material. Its working principle is that when the motor rotates to drive the fan impeller to rotate, the gas between the blades in the impeller also rotates, and these gases are thrown out under the action of centrifugal force. The gas velocity increases, so that the kinetic energy of gas is converted into static pressure energy in the flow, and then, with the increase of the flow rate, the kinetic energy is converted into static pressure energy By pressurization, static pressure energy is converted into velocity energy, and the gas is discharged through the exhaust port, and a certain negative pressure is formed in the middle of the impeller. Due to the negative pressure at the inlet, the external gas is immediately added under the action of atmospheric pressure, and the gas is continuously discharged and added under the continuous rotation of the impeller, so as to achieve the purpose of continuous blowing. Under the same power, the air pressure and air volume are generally inverse ratio. Under the same power, if the wind pressure is high, the air volume will be relatively low, and if the air volume is large, the wind pressure will be lower, so as to make full use of the efficiency of the motor
