User Manual for High-Temperature Centrifugal Fans

High-temperature centrifugal fans are corrosion-resistant ventilation devices. The main components of these fans are either treated with anti-corrosion coatings or made of corrosion-resistant materials, providing effective protection against corrosion. They are ideal corrosion-resistant ventilation devices for industries such as chemicals, pharmaceuticals, rare earths, smelting, and electroplating. Classified by airflow direction. High-temperature centrifugal fans are classified based on different airflow directions. High-temperature centrifugal fans. After the high-temperature centrifugal fan is started, the motor drives the impeller to rotate in a vortex pattern, drawing air in from the center of the impeller. Due to the dynamic action of the blades on the gas, the gas pressure and velocity increase; under the influence of centrifugal force, the gas is directed along the path of the blades into the housing and discharged through the outlet. High-temperature centrifugal fans consist primarily of an impeller and a housing. In high-temperature centrifugal fans, the impeller is mounted directly on the motor. Large and medium-sized high-temperature centrifugal fans are connected to the motor via a coupling or pulley. High-temperature centrifugal fans typically feature a single-sided air inlet and use a single-stage impeller. When large airflows are required on both sides, two consecutive impellers may be used. This configuration is also referred to as a high-temperature centrifugal fan. High-temperature centrifugal fans consist of an impeller, housing, and collector assembly, and are typically mounted on building walls. High-temperature centrifugal fans consist of a hub, impeller, streamlined body, housing, diffuser, and drive components. The blades are evenly distributed around the hub, typically numbering between 2 and 24. The greater the number of blades, the higher the static pressure. The installation angle of the blades in high-temperature centrifugal fans is typically 10° to 45°; the larger the installation angle, the greater the airflow and static pressure.
