Key component configuration
★drive device
•Fengshen series fan adopts Taiwan/German gearbox motor
•Fengxing series adopts the industry's first non carbon brush, large
torque, DC drive motor, replacing the traditional motor speed
reducer, realizing high integration, improving reliability and
transmission efficiency
★control device
•Fengshen series fan adopts Taiwan / Germany brand inverter stepless
speed change (optional explosion-proof controller) to configure
circuit breaker overcurrent overload protection, cooling fan and
other components
•Fengxing series fan adopts a special brush free controller
★fan blade
•The material of the fan blade adopts magnesium aluminum alloy T6
treatment, corrosion resistance, high strength, high toughness
•Advanced fluid simulation software CFD simulation and wind tunnel
test, in line with aerodynamic anti fatigue;
•With the function of delay start, the load and impact of the motor
are greatly reduced, and the service life is longer
★Structure components
•The structural parts are formed by Q235B laser, bending the
stiffener structure, and the thickest part is 8mm.
•Alloy steel high strength bolts and anti-skid nuts are used for the
bolts.
•Steel wire rope and turnbuckle tension structure to stabilize the
fan against falling
• The integrated chassis can prevent the risk of fracture, the
coupling anti falling structure can avoid screw defects, the
chassis can be dropped, the hole arrangement design of plywood
structure can prevent sliding, the adjustable structure is suitable
for any installation conditions, and the arc-shaped adjustable
waist hole can be adjusted to ensure the plane level of blade
chassis
Comparison of three refrigeration methods in 1000 square meter
plant
| Refrigeration mode | Quantity | Power/unit | Tall power | General comparison |
| Central air conditioner | 1 | 80KW | 80KW | The walls and doors and windows of the plant are required to be
insulated. The cost of one-time investment of the equipment is
high, and the maintenance cost of replacing the filter element and
adding refrigerant is high |
| Traditional industrial fan | 40 | 0.3KW | 12KW | The installation of traditional wall fans is limited by walls and
columns. The power lines of floor fans are scattered, which has
potential safety hazards. It is not safe for the hair of staff
members to be mixed into the fan blades, which occupies a small
space and covers a short service life |
| 7.3M large industrial ceiling fan | 1 | 1.5KW | 1.5KW | Large coverage area, long service life, low maintenance cost,
installation does not occupy the workshop space, safety and
environmental protection |
The energy consumption of large industrial ceiling fan is about 1 /
50 of that of central air conditioner and 1 / 10 of that of
traditional industrial wall fan
***Suitable places of installation: Any high enough structure of
factory,sport center,logistic place,car repair workshops,supermarket, airport,package
workshop,animal breading industry,any kinds of hall,as well as
fitness center etc.
***Height of installation: "Fengshen" series products for 6 meters
to 20 meters height.
"Fengxing" series products for 3 meters to 6 meters height.
***Solutions for the three main kinds of installation structures as
above shown pictures.
There are various forms of building structures. We provide you with
the installation methods of three common structures (right figure):
