Backward of wind turbines, aluminium alloy or pipes and other material production, have single into the wind and the double in two forms, can be processed into backward or forward. Supporting guide ring, 1.5 mm cold plate stretch forming, fixed jig drill mounting holes, high accuracy, ensure the installation. Wind turbines with advanced welding technology, school of dynamic balance processing, guarantee the stable running of rotor, are widely used in all kinds of fans and ventilation equipment.
Outer rotor backward centrifugal fan, no form of spiral case, convenient supporting various purification hvac equipment, installed in the device's frame, produced by the rotation of the fan centrifugal air, as they encounter inside casing wall to form a high air pressure, thus lianyuan constantly through filter layer, the formation of coaxial flow, after the outer rotor centrifugal fan, high pressure, air volume is big, obvious effect, is the best choice of small hvac equipment. Fan by outer rotor asynchronous motor, aluminum impeller, such as motor low temperature has the distinct advantage of the ventilation and heat dissipation from the cooling. To extend the life of the fan reliability. After the fan for curved impeller, with compact structure, big air volume, static pressure is high, small vibration, low noise, easy installation, etc. Is mainly used for purifying workbench, the purification unit, ventilation pipe dust removal, purification air-conditioning systems, refrigeration equipment facilities, such as environmental protection and pollution control, etc.
