EC centrifugal fan configuration with excellent aerodynamic efficiency of backward type centrifugal wind leaf. Built-in drive circuit board, has the speed feedback, locked-rotor protection, current limiting, soft start function, the direction of rotation is clockwise.
Storm of shenzhen technology co., LTD. Is a centrifugal fan rotor, outer rotor axial flow fan fan, mute, pipes, DC fan, blower, new trend person EC fan etc electromechanical integration products as the leading modern production enterprises. Fan, exterior rotor backward centrifugal fan/DC centrifugal fan/EC centrifugal fan. Outer rotor backward centrifugal fan, 100 mm133mm rotor diameter, 100 mm 175 mm to 190 mm, 220 mm and 225 mm, 250 mm and 280 mm, 310 mm and 350 mm, 355 mm400mm, 450 mm, 500 mm, 560 mm630mm mm800mm900mm 710 specifications, such as air volume size from 245 m3 / h - 10800 m3 m3 / h.
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.
Energy saving of precision air conditioning system EC EC centrifugal fan EC fan fan
Electronic commutation centrifugal fan:
Outer rotor fan, high efficiency and energy saving;
No vibration, long life;
Using brushless dc motor, the built-in circuit, can according to indoor temperature stepless speed regulation.
Low starting current, below the operation current (ordinary ac motor starting current is running current of 3.5 times)
Compared with the general asynchronous motor, save electricity for the whole year can reach 50%
The same working point of EC fan relative to ordinary AC fan, its power.
Because of the fan in the computer room air conditioning is non-stop running, running time is longest, so all the year round, the power consumption of fan for the whole units account for considerable proportion. By the figure below shows, such as in chilled water unit, selection of EC fan can save energy as much as 63% throughout the year
