Overview |
|
The aluminum ventilation centrifugal fan is a
professional ventilation device specially installed on the
building roofs to achieve effect ventilation, heat dissipation,
dehumidification and air exchange of the interior of buildings.
It can effectively exhaust the polluted air with smoke, dust,
oil mist and moisture in the buildings, has the advantages of
light weight, good corrosion resistance and high ventilation
performance, and can keep the good ventilation environment. The
centrifugal fan can be widely applied to hotels, schools,
hospitals, workshops and other buildings. |

Aluminum Alloy Structure
The
whole centrifugal fan is crafted with aluminum alloy materials,
effectively reducing the overall weight and the roof load and
further improving the application safety. |
|
Fan Impeller
The fan impeller is processed through finish
machining, has good dynamic balance, can ensure long-term stable
and continuous operation with low noise, and is safe, reliable
and durable.
|
|
|
|
|
Rainproof Cap
The
aluminum alloy rainproof cap is integrally formed and subjected
to crimping treatment, is light in weight, high in structure and
low in air resistance and has a good protection effect.
|
|
Fixing Buckles
The fixing buckles are designed for fastening
the top cover and the fan body to effectively protect the
internal motor and parts, and the fastening and loosening
operation is flexible and convenient.

Operation
Method |
|
1.
Before installation, carefully check whether the blade
is damaged or deformed due to transportation. If yes, it
should be repaired before installation.
2.
Check whether the blade and the air duct make contact
with the shell due to the loosening of the connecting
screw. If the clearance between the blade and the air
duct is not uniform, the clearance should be adjusted,
and the machine can be started only after the correction
is uniform and the screws are tightened.
3.
Before starting the fan, first of all, check whether
there are objects around the fan that hinder the
rotation, and whether the blade installation angle is
consistent.
4.
Check whether the insulation performance of the motor is
good. After switching on the power, check whether there
is friction, collision and vibration. After running for
one hour, stop the motor to check whether the heating is
normal.
5.
During normal operation, monitor whether the fan current
is within the normal range. In case of the following
circumstances, it should be shut down immediately for
maintenance:
(1)
The motor temperature exceeds 90℃.
(2)
The motor smokes.
(3)
The strong vibration or a greater sound occurs.
The
fan not used for a long time should be placed in a dry
place to avoid damage to the motor due to moisture. |
