Tunnel boring construction fan The fan has a high pressure. The low flow rate is suitable for wind transportation during processing such as grain, wood chips and cotton.
Tunnel boring construction fan Widely used for general ventilation or dust extraction, it can be used to discharge a mixture of wood chips, fibers and dust with air.
The fan is mainly composed of an impeller, a casing, an air inlet, a transmission group and the like.
1. Impeller: There are 10 pieces of back-inclined arc blades with A3 material welded in the middle of the arc-cone wheel cover and the flat-plate wheel. After static and dynamic balance correction, the operation is stable.
2. Case: welded with a common steel plate into a snail shell as a whole.
3. Air inlet: Make a convergent streamlined overall structure, bolted to the inlet side of the casing.
4. Transmission group: It consists of main shaft, bearing box and pulley. The main shaft is made of high-quality steel and the overall structure of the bearing housing. Rolling bearings are used, and the rolling bearings are lubricated with bearing grease.
