GY6-41 boiler centrifugal drum induced draft fan
Product details
GY6-41 boiler exhaust fan usage:
The GY6-41 boiler exhaust fan is a new series of low-noise fans designed to adapt to industrial boilers that use various media and are equipped with dust and smoke elimination devices, with a maximum total pressure efficiency of over 80%. It can be used under similar inlet conditions and with similar performance.
GY6-41 boiler fan type:
1. The position of the air outlet is represented by the angle of the air outlet of the casing.
2. Induced draft fans can generally be made in two types: clockwise and counterclockwise rotation.
3. The structure of the fan and the induced draft fan are composed of components such as impeller, air inlet, and casing. The bearing box is an integral structure, lubricated and cooled by engine oil, supported by a cantilevered structure, and the pulley and coupling are located on the outside of the bearing.
4. The transmission mode of the fan is: the induced draft fan adopts C or D type transmission, and the blower of boilers below 8.5 adopts A type transmission. The induced draft fan should be equipped with a regulating door. The fan impeller adopts a backward inclined circular arc blade, and the wheel cover is a combination of a conical curved surface and a streamlined air inlet, all of which use mold stamping technology to achieve good aerodynamic performance of the fan oil, low dust accumulation, low noise, and stable quality.
Characteristics of GY6-41 boiler fan:
GY6-41 boiler exhaust fan is a replacement product for boiler ventilation and induced draft fans. The design method used for the GY6-41 boiler exhaust fan includes selecting the appropriate fan type, reasonable fan operating conditions, selecting the optimal flow pattern, organizing the air source reasonably, carefully designing the blade shape, increasing the clearance between the air tongues, appropriately reducing the fan speed, improving the volute design, purifying the incoming flow, and minimizing secondary flow losses. The finite difference method is used to calculate the inlet and impeller cover profiles, and the smooth and uniform airflow at the impeller inlet is used as the optimization criterion for the outlet optimization design. Combined with the existing optimization design methods for fan impellers, volutes, etc., a comprehensive optimization design program integrating impellers, volutes, and air inlets was developed to obtain an aerodynamic sketch curve. Practice has proven that it can ensure both wind pressure and air volume, as well as high efficiency, low specific noise, and smaller fan size.
