Suction fan is the latest type of fan, axial fans are fans livestock farming, mainly used as negative pressure ventilation cooling works called suction fan. Negative pressure ventilation cooling ventilation and cooling project includes breeding meaning fan, ventilation and cooling simultaneously solve two problems. Suction fan is also used in the field of environmental protection curtain positive pressure air conditioning, pressurized air, pressurized hair and so on. Suction fan with a bulky, oversized wind tunnel, large diameter fan, large exhaust volume, ultra-low-power, low-speed, low-noise characteristics. From the structure of the material suction fan is divided into square galvanized sheet steel and glass flared suction fan suction fan. All the market square galvanized sheet suction fan structure and technical parameters of the basic agreement, suction fan type classification will be described in detail. FRP flared suction fan belt from drive mode is divided into different style and straight junction, suction fan type classification will be described in detail. Adjustable inlet vane inlet vane adjustment is achieved by adjusting the fan blade factory farming, the suction impeller flow direction changes, changes in the performance curve of the fan. Air-conditioning fan regulate the flow of imports are convoluted, inlet guide vane angle can be achieved for all operating conditions when the performance curve below zero; while a negative adjustment of imports convoluted flow can improve the fan pressure and flow, but there are certain limits adjustment range. Because adjustable inlet vanes with a wide adjustment range and higher economic FRP fan culture, and to achieve automatic adjustment, therefore, are widely used for air-conditioning fan.
