Inlet vane adjustment inlet vane adjustment is achieved by adjusting the blade Hunan Leiyang culture curtain fan, flow direction of the suction impeller changes, change the fan performance curve. Air-conditioning fan inlet flow positive convoluted regulation, can achieve the inlet guide vane angle is zero when all working conditions the following performance curves; and negative regulation of the flow of imports of farmed convoluted fan can increase fan pressure and flow, but there is a certain adjustment range limit. Since the inlet vane adjustment has a wide adjustment range and high economy, and to achieve automatic adjustment, therefore, it is widely used for the air-conditioning fan. Features 1 fan culture, fan are: stainless steel blades, with air volume, no distortion, no breaking, attractive and durable. 2, belt use automatic belt tensioner with the belt is not loose, out with. 3, the pulley belt pulley using pay more gluten sandblasted, improve aesthetics Artemisia city of Hebei farming fan curtain, eliminate stress, increase strength. 4, France imported bearings bearing high-strength, low noise, and long service life. 5, blinds made of stainless steel Chuzhou culture curtain fan, automatically open and close, dust, water, nice.
