The centrifugal drum and draft fan of GCU Y6-41 boiler is a new series of low noise boiler drum with maximum full pressure efficiency of more than 80% designed to adapt to industrial boiler with various coal quality and equipped with dust abatement device. The intake condition of induced fan is the same as that of other low noise boiler. The performance is suitable for those who can choose.

 

GG Y 6-41 series centrifugal fan, is boiler drum, fan generation products.

 

The design methods used in the series of GCU Y6-41 fans are as follows: selecting the appropriate fan type, reasonable operating parameters of the fan, optimizing the flow pattern, organizing the air source, carefully designing the blade shape, increasing the gap between the air and tongue, appropriately reducing the fan speed, improving the design of the volute, and improving the design of the volute. The design principles of purifying the incoming flow and minimizing the loss of secondary flow are combined with the numerical calculation of the inlet of the machine and the cover of the impeller by using the finite difference method. Based on the uniformity of the flow field at the inlet of the fan impeller, the optimal design of the inlet is carried out. The above method is combined with the original optimization design methods such as the fan impeller, the volute case and the inlet air.Optimized design program, lower specific noise level and smaller fan size.

 

1. The driving mode of fan is A-motor direct transmission.

 

C-belt pulley drive

 

D-coupling drive

 

2, the induced fan from the transmission face, and can be made clockwise rotation or counter-clockwise rotation two types.

 

3. The air outlet position of the fan is expressed by the air outlet angle of the housing. Both clockwise rotation and counterclockwise rotation can be made into four angles: 0 degrees 90 degrees and 180 degrees and 270 degrees.

 

Customer order, according to the use conditions must indicate the rotation and outlet angle, in order to meet the use.

 

Fourth, the structure of the fan:

 

The fan and blower produced by our factory are made up of impeller, inlet, housing, etc. The bearing box is integral structure, oil lubricated cooling, cantilever support, belt pulley, etc. The shaft coupling is outside the bearing. The draft fan adopts type C or D drive boiler blower with A transmission, which is easy to maintain.

 

The draft fan should be equipped with the adjusting door. If the user needs to adjust the door, they can put forward the order to our factory separately.

 

Fan impeller, adopting backward tilted circular arc straight blade, the cover of which is a combination of arc conical curved surface and streamline inlet. Under the production conditions of die stamping forming, our factory has good aerodynamic performance, not easy to accumulate ash, and low noise. Precise geometry and stable quality.


We could Design and Produce the Marine fan,Industrial Fan,and Other Ventilation Equipment according to your detailed requirement !
