Driving device
The external rotor permanent magnet synchronous motor is
designed and manufactured by the company's shareholder with more than 20 years
of experience in permanent magnet motor design and manufacturing. High efficiency,
energy saving, energy consumption reduced by 30%, direct drive has no mechanical
deceleration, quiet, stable operation and lifelong maintenance free.
Fan blade
The fan blade surface is designed by large-scale hydrodynamics
simulation software, and the air supply effect is the best; The wall thickness is
increased, and four stiffeners are added in the inner cavity, which greatly improves
the bending and fracture resistance; High performance aluminum alloy 6005t6, 10%
higher than 6063; Fluorocarbon paint baking / electrostatic plastic spraying
treatment on the surface, wear-resistant and easy to clean.
Chassis
Made of high performance structural steel; The upper and lower
double chassis are clamped with 12 high-strength bolts to connect all blades as a
whole and eliminate looseness and noise.
Fin High performance structural steel is made by laser, and its bending and fracture
resistance is 15% higher than that of aluminum alloy, so as to eliminate deformation
and fracture.
Control system
As a shareholder of the company with more than 20 years of
experience in frequency conversion control system design and manufacturing, the
company specializes in the design and manufacturing of industrial large fans,
multiple protection such as electronics and logic operation, and super heat
dissipation devices, providing the most perfect guarantee for the safe, stable and efficient operation of fans.
a fastening. All 12.9 / 8.8 high-strength bolts of domestic well-known brands are adopted, with guaranteed quality; Adopt mechanical locking nut to prevent loosening; With "loctite" locking glue, there is no hidden danger for permanent locking.
Safety devices and measures
Six safety protection:
1. Both sides of the connecting plate between the fan and the mounting beam are
folded to form a [shape to prevent deformation and bending;
2. The connection splint and the beam mounting plate are of deep sawtooth
structure, which are locked with each other to prevent falling off;
3. The connection of all parts of the fan is L-hook connection or mortise and tenon
connection and fully welded with double protection;
4. After the fan is installed, it shall be tightened and fixed on the building with 4 steel
ropes to prevent shaking;
5. Steel wire rope connection is added between motor shaft and building beam for
multiple protection;
6. The control system has complete overload, overcurrent and overheating
protection.
