Glass fiber reinforced plastic animal husbandry fan

Glass fiber reinforced plastic (FRP) anti-corrosion fan refers to a fan made of glass fiber reinforced plastic (FRP), which has the same appearance and size as a steel fan, except that the shell and impeller are made of FRP, and its main characteristics are corrosion resistance, acid and alkali resistance. It is a type of anti-corrosion fan. FRP anti-corrosion fan is suitable for ventilation and exhaust in office buildings, shopping malls, theaters, hospitals, factories, enterprise workshops, basements, and other places. The gas conveyed should be free of viscous substances, The gas temperature shall not be greater than 80 ℃, and the content of the medium shall not be greater than 150mg/M3.

1) FRP anti-corrosion fan workshop, industrial use: factory buildings, warehouses, livestock farms, etc.

2) FRP anti-corrosion fan buildings and public residences: local ventilation for high-rise buildings and general buildings.

3) Various public places such as schools, hospitals, laboratories, stadiums, cinemas, hotels, etc.

4) Ambient air conditions for use of fiberglass corrosion resistant fans: dust content and other solid impurity content Temperature ≤ 150mg/M3 ≤ 80 ℃

Key points for installation of negative pressure fan cooling equipment

Firstly, the installation location selection of negative pressure fan ventilation and cooling equipment is a key point, and it is recommended to choose the floor or platform as much as possible for maintenance and repair; When arranged outdoors, the motor should be equipped with a protective cover that prevents sunlight and rain. When the motor power of the centrifugal fan is less than or equal to 75kW, it is not necessary to install a valve that is only used for starting. When selecting a centrifugal boiler induced draft fan for discharging high-temperature flue gas or air, a valve for starting should be installed to prevent motor overload during cold operation.

2. The installation pedestal (foundation) of negative pressure fan ventilation and cooling equipment should have sufficient strength, stability, and durability, and the vibration of the pedestal should meet the following requirements:

1) The natural vibration frequency of the basic device shall not exceed 1/3 of the speed of the motor and fan;

2) The difference between the vibration speed of the negative pressure fan ventilation and cooling equipment during operation and the vibration speed of the fan at rest should be more than three times.

When installing negative pressure fan ventilation and cooling equipment on building components, vibration isolation measures should be taken.

4. Flexible joints should be installed between the inlet and outlet of the ventilation and cooling equipment of the negative pressure fan and the air duct. The inlet and outlet ducts and other devices should be supported separately and firmly supported by the foundation or other components of the building. The casing should not bear the weight of other components.

Performance characteristics of negative pressure fan
