The structure of the closed fan mainly includes the casing, the rotor, the reducer, the front cover and the rear cover of the casing, etc. Different components perform their duties and perform different functions.

The fan cover (used to place the rotor machine tool) is the main body of the fan. It has butt joints with upper and lower flanges, with a circular dustbin in the middle, A and B design, in line with domestic standard sizes. The observation hole is set on one side of the shell, and the left and right mouths are the same size. The front cover and rear cover of the fan housing have been precisely processed, and the dedicated bearing positions are tightly integrated to ensure concentricity with the rotor. The connection with the reducer is a flat connection design and matched with the processing to ensure a complete concentric structure.

The fan speed reducer is a planetary reducer (speed 25-40), the speed of which is adjusted by the discharge amount. The reducer and the motor are integrated, and a special reduction motor is used. The rotor of the air shutter is made of cast iron (the rotor is divided into cast iron, cast steel and aluminum). The rotor rotates in the housing to transfer the medium from top to bottom and has a circular structure. Both sides are disc-shaped, and the middle is a six-part trapezoid. In the slit structure, the center of the rotor is a permeable circular hole, which is machined to penetrate the center of the spindle. Install sealing strips as needed to improve sealing performance.
