Dawang fans Configuration
1.Motor:Custom manufacture motor,NORD German.Low gear gap assembly process, gear grinding process, low noise,No vibration,free maintenance, more safety.Get CCC¡¢CE¡¢UL certification
2.Frequency Converter:Top Frequency Converter configuration, Schneider electric suit.Safety protection module, automatically cut off when accident,protection grade IP55.Passed UL,EMC,LVD,ROHS certification
3.variable cross-section Streamlined blade:1.5mm thick 5052 aero-grade 5 pieces aluminum plate are adopted, variable cross-section streamlined blades( equal string length theory of Aerodynamics).Fan blade gradually narrows from root to tip and thins to the tail then widens, single blade weights is 7.7kg
4.Wheel hub chassis:7075 aero-grade aluminum material,after CNC machining, chassis precision tolerance controlled at 100¦Ìm to ensure balance.
5.Main Frame:Q345 high strength steel structure laser cutting,after pickling and phosphating,coating thickness up to 80 ~ 100 microns, curing temperature is 190℃. Surface hardness has no scratch by 2H pencil test, up to GB6739-86 standard
6.mortise and tenon connection:Fully mortise and tenon connection,ensure the overall fan safety
Dawang fans Advantage:
1.Blade shape- Streamlined variable cross-section
Blade gradually narrows from root to tip and thins to tail then widens
like plane wing, more conform to the equal string length theory of aerodynamic
Fan volume is more even, higher and there is no hole in the middle, low air resistance, save energy consumption.
2.Blade weight-light
Each blade is 7.7KG,total weight for 5pcs is 38.5KG.Small blades ,light weight, reduce the motor load, increase the fan life.Low energy consumption.
3.blade petiole joint -- full mortise and tenon joint
The "convex" shape petiole and "concave" shape buffer device are locked with bolts, each blade is riveted together with damping device by 16 rivets. Blade, damping device and petiole become a whole, torsional and shear force reduced.
