英文版  The contemporary fan performance advantage
 

A contemporary all the various components of the fan in front of the painting are using shot peening pretreatment , effective removal of metal oxide , oil , and thus more paint and metal character focus , painting two durable.
2 fan most of the welding process using a mechanical automatic welding , the welding quality is generally wind turbine manufacturers can not match .
3 fan duct using a special machine CNC hydraulic support design ( exclusive domestic ) the hairdryer processing , No. 8 hairdryer roundness of less than 0.5 mm , and 8 to the 12th hairdryer roundness less than 0.8mm , 12 more than the wind tube -roundness less than 0.95mm . Thus the fan impeller blade tip clearance and duct wall be effectively controlled , the higher the efficiency of the fan , pneumatic be effectively guaranteed .
All contemporary two-speed fan the YDT two-speed motor , YD motor than other manufacturers in more than 45% of the low - speed energy-saving .
5 , all the contemporary explosion-proof fan with steel impeller, the tip inserts welded H62 brass process, using the standard is higher than the national standard international ISO standards .
6 All fans than the noise indicators were less than 27dB ( A ) , far less than the national standard limited 35db ( A ) .
7 fan motor shall be detected before storage of the no-load current of the motor , when the value is less than the prices of the company the subject of the provisions are allowed to use , from the source to ensure the quality of the heart of the fan - motor .
8 All fan rotor blades and guide vanes are used repeatedly amended in accordance with the provisions angle expanded view of CNC plasma cutting , the use of electric heating mold pressed , to prevent the move , the guide vanes rebound and local overheating , fan equipment to ensure installation angle and up to the aerodynamic data accurate performance and durability.
9 wind chassis contemporary company specializes in mold the framework of the special plant rolled high - quality steel sections , box angle using the two-tier structure ( both aluminum alloy , covered with plastic) , the wind chassis unilateral intake gap not less than 1.2 impeller diameter , all aerodynamic data to be effectively guaranteed .
Rectangular duct fans with external rotation of the motor 10 , the volute vertical plate stamping manufacturing screw holes process, using a jig positioning , resulting in cochlear Road is smooth and accurate, the accuracy of aerodynamic parameters , the noise is very low .
