[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Fan] trends: more and more obvious trend of economic globalization, interdependence of national economies will further international economic cooperation and exchanges between the increasingly close fan technology, international market in a significant crossover and integration phase. Meanwhile, the global industry is accelerating the pace of structural adjustment, the size and depth of the international division of labor are major progress in the developed world industrial production to capital-intensive and technology-intensive industries, labor-intensive products to developing countries and regions. This is for our country to play their own advantages, among the international market provides a good opportunity for development. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product -] impeller fan blower fan is the main component, its geometric shape, size, number of leaves and manufacture of precision have a significant impact on performance. Static balance impeller or fan balancing correction in order to ensure smooth rotation. The export orientation of different blade impeller into forward, radial and backward three types. Front tilt toward the top of the impeller vanes of the impeller rotation direction; top blade radial impeller is in the radial direction, is divided straight blade and curved blade; after rotating reverse tilt toward the top of the impeller vanes of the impeller. The maximum pressure in the flow and the number of revolutions constant forward impeller, the minimum, but the efficiency is generally lower the required diameter of the impeller; pressure after the impeller contrary, the resulting minimum, the required maximum impeller diameter heaters, and general efficiency high; radial impeller in between. Vane-type lines straight blade simplest and most complex airfoil blades. In order to have the right blade surface velocity distribution, generally using curved blades, such as blades, such as the thickness of the arc. Impeller cover discs usually have to increase the strength of the impeller and reduce gas leakage between the blade and the casing. Coupling the blade with the cover plate by welding or riveting. Lighter weight impeller welding, smooth flow. Low, medium small centrifugal fan impeller is also made of aluminum alloy casting. When the axial fan work, power machine driven impeller rotating within a cylindrical enclosure, gas enters from the collector to obtain energy wind chassis through the impeller, increasing the pressure and speed, and then discharged in the axial direction. Arrangement of the axial fan has a vertical, horizontal and inclined three, small, only about 100 mm impeller diameter, large up to 20 meters.
