Centrifugal fan bearing maintenance
Centrifugal fan basic knowledge summary (including: principle, structure, outlet direction, blade type, theoretical characteristics)
1. The working medium is axially injected into the impeller, enters the blade flow passage, and is transformed into vertical and radial movement of the fan shaft; 2. Under the action of the blade, the medium obtains energy increase: static pressure increases and kinetic energy increases; 3. The medium can be transported if the energy to be raised is sufficient to overcome the resistance.
