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 centrifugal fan made of FRP anticorrosive material for its outer shell. Its working principle is that when the motor rotates to drive the impeller of the fan, the gas between the blades of the impeller rotates along with it, and it is thrown out under the action of centrifugal force. The gas flow rate increases, which makes the gas flow in the impeller. The kinetic energy is converted to static pressure energy, and then with the increase of fluid pressure, the static pressure energy is converted to velocity energy, and the gas is discharged through the exhaust port, and a certain negative pressure is formed in the middle of the impeller. Because the inlet is negative pressure, the external gas is immediately added under the action of atmospheric pressure, and continuously discharged and compensated under the action of continuous rotation of the impeller. Input gas to achieve the purpose of continuous blast. Under the same power, the general range of wind pressure and air volume is inversely proportional. Under the same power, if the wind pressure is high, the wind volume will be relatively low, and if the wind volume is large, the wind pressure will be lower, so as to make full use of the efficiency of the motor.
