Blower accessories impeller

Model Number: 4-72 blower impeller Brand Name: Tong Tian Key Specifications/Special Features: Main products are: 4-72, 9 -, 9-19 and 26, 9-28, 35, 5-9-47, 48, 4-5-73, 79, 4-4-79, 6, 6-48-41 and 46, 6 -, 6 -, 6-23, 25, 30, 9-38, 39, 8 to 18, 10-8-19, 10 to 21, all kinds of high pressure, medium pressure and low pressure blower impellerlow fan impeller features:Axial flow impeller of the wind direction and the wind direction, wind and intake levels outCommonly used in air volume is larger, wind pressure from bottomSuch as the transformer room, computer room, workshop and sidewall wall exhaust or air supplyHenan accer blower manufacturer production of axial flow fan WEX sidewall exhaust fan, blower, T35 axial flow fan, DZ WSP side-wall pipeline axial flow fan, DFBZ square wall axial flow fanHenan accer blower manufacturer production of axial flow fan air volume, low pressure, low noise, grazing type blade before useMaterial variety, can be made into glass steel, carbon steel, aluminumCentrifugal fan impeller features:Centrifugal impeller of the wind direction and the wind direction is 90°Generally applicable to high pressure, large air volumeHenan accer blower manufacturer production of centrifugal fan with RTC all-aluminum no volute centrifugal fan centrifugal fan, ISQ roof box, cabinet HTFC low noise centrifugal fan, low noise centrifugal fan for DBF box, GDF pipeline centrifugal fan
Centrifugal impeller can be divided into the front curved impeller, the impeller, the curved impeller
1, before the curved impeller: linear velocity direction of the airflow direction and the blade Angle for the acute angle
Features: low speed, large volume, low static pressure (relatively backward, the curved impeller), molding process is simple and low cost
Before the curved impeller speed too high will cause the motor overload, so before using the curved impeller fan does not allow no-load running
2, backward of impeller: air flow direction and the direction of the linear velocity of the blade Angle for the obtuse Angle, blade to form
Features: high speed, wide speed range, small volume, high static pressure, however, high efficiency (relative curved impeller comparison)
After 3, curved impeller: air flow direction and the direction of the linear velocity of the blade Angle for the obtuse Angle, blade surface form
Features: high speed, large volume (larger than the backward of impeller), higher static pressure, higher efficiency, however
After performance and backward curved impeller of the fan impeller of the fan performance is very similar, but after the curved impeller efficiency higher, also more stable performance, processing more difficult, widely used in the field of high pressure fan
