What is centrifugal backward impeller?
What is impeller structure?
The backward impeller includes a circular annular blade bottom plate, a hub, blades and a guide ring. The hub is integrated with the inside of the circular annular blade bottom plate. The top of the hub is provided with a cylindrical plastic shaft sleeve which is integrated with the blade. The inlet end to the outlet end of the blade are distorted. The inlet angle of the blade is divided into the upper inlet angle near the deflector and the lower inlet angle near the bottom of the circular annular blade.
The outlet angle of the blade is divided into The upper air outlet angle near the deflector and the lower air inlet angle near the bottom of the circular annular blade; the upper part of the blade is composed of a connected and non-connected area. The corresponding air outlet area is 70% -75%. The advantages of the backward impeller are novel structure, large air volume and low noise.
