Forward-Curved Double-Inlet Centrifugal Fan Types and Structure

Forward-Curved Double-Inlet Centrifugal Fan Types and StructureForward-curved double-inlet centrifugal fans feature dust-resistant properties and wear resistance, making them suitable for exhausting gases containing dust, wood chips, fine fibers, and similar materials. When gases contain hard particles, a dust removal device must be installed upstream of the fan. Additionally, forward-curved double-inlet centrifugal fans can also serve as general ventilation fans. 1. Types of Forward-Curved Double-Inlet Centrifugal Fans: Generally, these fans employ a single suction design encompassing various mechanical dimensions. They primarily come in two types: right-rotating and left-rotating. This forward-curved double-inlet centrifugal fan is driven by a V-belt. When pressure and flow requirements change during operation, adjustments can be made according to the specifications in the performance table. 2. Construction Overview of Forward-Curved Double-Inlet Centrifugal Fans: These fans consist of an impeller, air inlet, casing, transmission components, and motor. Typically, the impeller features 12 blades welded to a conical wheel with an arc-shaped profile. The blades, blade cover, and wheel are constructed from 16Mn steel. The entire propeller undergoes dynamic and static balancing correction for stable operation. Under normal circumstances, the impeller installation and disassembly of the forward-curved double-inlet centrifugal fan is performed on one side of the casing. The air inlet of the forward-curved double-inlet centrifugal fan is positioned on the side of the fan.
