FRP fans are mainly used for indoor ventilation in industrial and civil buildings. There are two kinds of FRP fans: centrifugal fan and axial fan. The structure of direct-connected vertical device of motor can be divided into ordinary type, explosion-proof type, temperature-resistant type, humidity-resistant type, corrosion-resistant type and so on according to different service conditions. The shell and impeller can be made of different materials according to the actual situation, and the wind cover can be made of light and corrosion-resistant FRP materials. The FRP fan is planned according to the outdoor climate conditions, and the hood is made of FRP material, which can resist the corrosion of rain, snow and humid atmosphere, and the motor and metal parts are also strictly protected against corrosion; The air inlet is equipped with a louver damper, which can be opened and closed actively. When the fan works, the air door opens, and when the fan stops working, the air door closes. Fan blades are airfoils made by precision planning and precision machining technology, which have excellent air performance. After the impeller is formed, check the static balance and dynamic balance one by one to ensure the smooth and reliable operation of the fan; The supporting structure of motor and impeller is a patented scheme. When the motor and the impeller are supported together, as the rear guide mechanism of the impeller, it can reduce the circumferential rotation of the outlet airflow and obviously improve the fan power; The hood is streamlined, and the outer surface is made of gel coat resin film, which makes the fan look bright, uniform in color and beautiful. Suitable for ventilation and exhaust in office buildings, shopping malls, theaters, hospitals, factories, workshops, basements and other places. The gas to be transported should be gas without viscous substances, the gas temperature should not be greater than 80℃, and the mass of substances contained in the medium should not be greater than 150mg/M3. At present, it is mainly used in different fields, such as municipal and urban transmission and distribution networks. This is mainly because FRP pipes have the advantages of non-toxicity, no secondary pollution to water quality, no need for any anti-corrosion measures, very long service life and inconvenient installation and operation, so they are widely used.
Glass fiber reinforced plastic air ducts are all metal structures and glass fiber reinforced plastic structures. The practice of some projects proves that the air environment of the roof is not good, especially after the rainy season, the steel parts are seriously corroded, which reflects that the corrosion resistance of the steel structure rain cap is not ideal, which seriously affects the service life and beauty of the roof fan. The strong plastic roof fan can solve the corrosion problem, but the pipeline and the base part run for a long time and are easy to fall off, which leads to the collision between the fan and the motor and causes an accident.
