Energy Efficiency Backward Forced Draft Industrial Centrifugal Fans
Introduction
The Energy Efficiency Backward Industrial Centrifugal Fans can meet the performance requirements of large flow and high pressure at the same time, and has the characteristics of high efficiency and low noise. It is a series industrial centrifugal fan products with a wide range of performance.
The designed max full pressure efficiency is higher than 80% new series boiler ventilation centrifugal fans and induced draft fans with the low noise.
The Energy Efficiency Backward Industrial Centrifugal Fans can be selected if the intake conditions are equivalent and the performance is suitable.

Advantages and Features
Choose the right industrial centrifugal fan type, reasonable operating condition fan parameters, preferred flow pattern ,reasonably organize the gas source, carefully designed leaf type, increase wind tongue clearance, properly reduce the fan speed, improvement volute design, design principles for purifying the flow and minimizing secondary flow losses and so on. Combined with the finite difference method numerical calculation machine air inlet and impeller wheel cover type line, and the uniformity of the flow field at the fan impeller inlet is used as the optimization criterion to optimize the air inlet. The above method is combined with the original fan impeller, volute and other optimization design methods to integrate the optimal design procedure of the impeller, the volute and the air inlet, the lower specific noise level and the smaller fan size.
