220V Cooling Fan blade balance

Performance "220V Cooling Fan" blade balance related to the entire DC fan, DC fan blades than the positive balance of the general dynamic balance, it is the principle of adjustable vanes for DC and single-stage fan rotor blade adjustable DC fans, Because only one level of the impeller, mass imbalance caused due to wear it all focused on the impeller, "220V Cooling Fan" balancing process is a single plane balancing process, namely static equilibrium process. Flow cooling fan is a DC voltage and electromagnetic induction, the electrical energy into mechanical rotation so as to drive the blades. DC fan impeller and blade design, with the air flow DC fan with fan pressure and compression capability is closely related to the collision, serious point that affects the whole "220V Cooling Fan" grade and quality, how to design efficient and simple process of DC fans has been a major issue of scientific research personnel research, design and efficient impeller blades is the main way to solve this problem.
