 FRP roof fan

Keep working environment clean:

   FRP roof fan is a high quality fan product, and has been gradually applied to a wide range of applications. Wind turbines require very high working conditions. Clean up the working environment of FRP roof fans at any time. The surface should also be kept clean. No dirt will appear in the machine's inlet and outlet. Therefore, we will clean up the FRP roof fans and clean up the dust every once in a while.

During the operation of the FRP roof blower, if we hear abnormal noises, the touch motor will feel hot, can not start, stop running in time, then test the blower. When the FRP roof fan is still working, it is strictly prohibited to carry out maintenance. After repair, try running the fan for 10 minutes to ensure that there is no fault and then run again.

The roof fan adopts the mold or centrifugal impeller, the direct drive of the fan motor, the anticorrosive wind cap, the metal or FRP duct base, which has the characteristics of corrosion resistance, light weight, high strength, smooth operation, simple maintenance, low noise and excellent performance. It is widely used in the ventilation and ventilation of various industries such as power generation, chemical industry, rubber, pharmaceutical, food processing, metallurgy and other advanced civil buildings. According to different usage environment and conveying medium, impeller can be made of aluminum alloy, steel plate, engineering plastics, FRP and other materials, and made into conventional, anticorrosive type, explosion-proof type, anticorrosive and explosion proof type. Optional accessories: as required, gravity type check valve (or electric type), bird protection net, maintenance switch, centralized control box and other accessories can be provided.
 

Characteristic

(1), the specification form is many, the application scope is broad: according to the pressure of use occasion, the S and the noise difference, choose the following two forms of fan:

(5) axial flow roof fan: Code DWT- type, suitable for use in medium low pressure and large flow fi. At the same time, according to the user clamping, it can also be designed to be bidirectional reversible reversible, which has the characteristics of equivalent in positive and negative conditions.

(6) centrifugal roof fan: Code DWT-II, suitable for occasions with smaller S and higher pressure requirements.

12) high efficiency and low noise: the fan adopts advanced CAD system software, and is designed and developed through multi-objective optimization. By adopting the same diameter, different speed, different angles and different leaf shapes to meet the requirements of different working conditions, the fan and the system can be matched to achieve energy saving and noise reduction.

(3) light weight. High strength and corrosion resistance: fan impeller can be made of different materials according to the different corrosiveness of the working medium. They are made of ABS (engineering plastics), steel FRP (FRP) and aluminum alloy sheet. For the centrifugal fan with high pressure and large fan speed, the surface of the impeller is specially galvanized and sprayed. Corrosion resistance not only reduces the width of the whole machine, but also has good corrosion resistance.

(4K running smoothly and long life: this fan has a small inertia IFT, high dynamic balance and smooth operation, and all the performance requirements in the plant internal control standard are higher than that of the wind turbine industry standard, so as to ensure the long-term and stable operation of the fan.

It has wide application: the fan can be manufactured to explosion-proof, flame retardant, and suitable for aging, pumping, combustible, easy to bear and corrosive gases.

Beautiful appearance: the wind lintel of the fan is made of FRP, and its outer surface is made of imported gel coat resin film. The surface transition is soft, elegant and practical.

Conditions of use: the medium temperature is not more than 60 feet. There is no S sticky substance in the gas, and the dust FI is less than 100mg/m3.
