Introduction to Cabinet-Type Centrifugal Exhaust Fans

Introduction to Cabinet-Type Centrifugal Exhaust Fans

Generally speaking, the primary characteristics of cabinet-type centrifugal exhaust fans are: high airflow volume, high static pressure, and excellent wear resistance for long-term use in dusty environments, ensuring extended service life. Consequently, these fans are highly favored by customers for dust extraction applications. In practical use, they are primarily employed to exhaust mixed air containing wood chips, fibers, and dust. Examples include furniture factories, wood processing plants, and cement plants. Airflow and Pressure Analysis: Under normal operating conditions, the airflow range typically spans 755–56,900 m³/h. Total pressure: 350-2043 Pa. Currently, cabinet-type centrifugal exhaust fans for dust removal are primarily available in right-handed and left-handed configurations. For transmission-group fans, clockwise rotation of the propeller is termed right rotation, denoted as "R." Counterclockwise rotation is termed left rotation, denoted as "L." Cabinet Centrifugal Exhaust Fan Outlet Angle Analysis: In practical applications, the outlet position of cabinet centrifugal exhaust fans is typically indicated by the outlet angle of the casing. The "left" and "right" angles can be one of six values: 0°, 45°, 90°, 135°, 180°, or 225°. Overview of Cabinet Centrifugal Exhaust Fan Construction: Key components of dust-removal centrifugal fans include the impeller, casing, inlet, and transmission assembly. The impeller is a critical component for regulating static and dynamic balance, ensuring smooth operation. Typically, the casing is welded from ordinary steel plates to form a complete volute. The drive section of cabinet centrifugal exhaust fans consists of the main shaft, bearing housing, and pulley.
