Product details

XH-CM-11 Medium pressure centrifugal fan

Product Introduction
XH-BI- 11 boiler fan is a new series of low-noise boiler drum, induced draft fan, designed for the use of various coal quality and equipped with dust and smoke elimination device for industrial boiler and the highest total pressure efficiency is higher than 80%, where the air intake conditions are similar, performance and adaptability can be selected.

Product Characteristics
XH-BI- 11 boiler fan  replacement products.
The design principles include selecting appropriate fan type, reasonable working parameters of fan, optimizing flow pattern, reasonably organizing air source, carefully designing blade shape, increasing air tongue clearance, appropriately reducing fan speed, improving volute design, purifying inlet flow and minimizing secondary flow loss. Combined with the finite difference method numerical calculation of the machine inlet and impeller cover profile, and the flow field uniformity at the inlet of the fan impeller as an optimization criterion to optimize the design of the inlet. Combining the above method with the original optimization design methods such as fan impeller and volute, the optimization design program integrating impeller, volute and air inlet, as well as the lower specific noise level and smaller fan size, is synthesized.

Type
1.The driving mode of fan
Type A- direct motor transmission
Type C - pulley drive
Type D - coupling drive
2.The induced draft fan, facing up from the driving part, can be made into clockwise rotation or counterclockwise rotation types.
3.The outlet position of the fan is indicated by the outlet angle of the housing. Clockwise rotation and counterclockwise rotation can be made into 0 degrees, 90 degrees, 180 degrees, 270 degrees four angles. 
When ordering products, customers must indicate the direction of rotation and the Angle of outlet according to the conditions of use, so as to meet the requirements of use. 

Structure
The fan and blower produced by our factory are all composed of impeller, air inlet, machine shell and other components. Bearing box for the integral structure, oil lubrication cooling, cantilever support, pulley, coupling outside the bearing.The induced draft fan is driven by c-type or d-type; Boiler blower under No.8.5 adopts type A transmission for easy maintenance.
The induced draft fan shall be equipped with adjusting door. If the user needs to adjust the door, order can be put forward to our factory individually.
Fan impeller, the use of tilting straight arc blade, wheel cover for the arc cone surface and streamlined air inlet lap combination, in the full use of die stamping forming production process, so that our factory has good aerodynamic performance, not easy to accumulate dust, low noise, geometric size accuracy, quality stability characteristics.
