The centrifugal roof row is mainly suitable for places where factories, laboratories, high -rise housing, basement, bathrooms, gymnasiums and other industrial and civilian buildings need ventilation and ventilation. It is especially suitable for damp and corrosive gas emissions.
The main feature is that the anticorrosive performance is excellent, the flow is large, the static pressure and efficiency are high, the noise is low, and the operation is stable and reliable.
Functional characteristics of centrifugal roof exhaust fan
The centrifugal roof exhaust device is the mechanical energy of the input to improve the mechanical of gas pressure side by side.FRP centrifugal fan is a fan made of FRP material, also known as anticorrosive centrifugal fan.
It has the characteristics of strong anticorrosive performance, long service life, and stable operation.
Generally, centrifugal roof exhaust device can be used in occasions with corrosive gases and emits corrosive gases.The gases they transport are not allowed to contain viscous substances, dust and hard particles less than or equal to 150 mg/m3, gas temperature less than or equal to 60 degrees, and relative humidity less than or equal.High -temperature places are not suitable for glass reinforced reinforced fans.
Installation and maintenance of centrifugal roof exhaust fans
1. The foundation of the installation must be higher than the roof, the surface is required to be flat to prevent water leakage, and the foot bolts must be embedded.
2. Add a layer of 5mm rubber sheet with a pad between the fan base and the foundation to reduce vibration. The ground foot bolts should be equipped with a spring cushion ring to prevent loosening during use.
3. Check the components of the fan in detail before debugging. The rotating impeller should have no dullness and cards and wipes.
4. At the beginning of the trial transportation, first click the motor to check whether the rotation direction of the rotation of the leaves is correct (looking down at the impeller should be rotated against the time).
5. There should be no abnormalities during testing or normal use, and voltage, current, vibration, and noise should be within the normal range.
6. During the operation, you should stop immediately when you encounter the situation.
① strong vibration
② The noise suddenly increased or made an abnormally sound
③ The motor has white smoke
④ The temperature of the motor and bearing is too high.
7. When the wind door is an electric wind door, the wind door is opened when the fan is turned on; when it is closed, turn off the fan first and then turn off the wind door.
8. Starting 72 hours and every half a year, the fan connecting parts and fasteners should be loose, adjust the transmission belt tight, and add lubricating oil (fat).
9. In the event of snow in winter and frozen, it must be moved frequently to prevent the exit of the snowst head.
10. After the long -term shutdown, you should re -check the normal operation and put it on the normal operation.
The above is the functional characteristics and installation and maintenance of the centrifugal roof exhaust fan
