Centrifugal blower is a common mechanical equipment widely used in industrial production processes for ventilation, air exchange, and air supply. It has the characteristics of simple structure, reliable operation, and high efficiency, so it is favored by many enterprises and factories.

Firstly, the working principle of a centrifugal blower is to utilize the centrifugal force. When the electric motor drives the impeller to rotate at high speed, the gas is sucked into the blower and rapidly accelerated. As the gas accelerates, the centrifugal force generated pushes the gas towards the outlet of the centrifugal blower, thereby achieving gas transportation and increasing pressure.

Secondly, the structural design of a centrifugal blower is relatively simple, usually consisting of an electric motor, blower housing, impeller, inlet and outlet pipelines, and other parts. Among them, the impeller is the core component of the centrifugal blower, playing a crucial role in driving gas movement. The impeller is generally composed of several curved blades, which push the gas towards the outlet through the rotation of the blades.

The application range of centrifugal blower is very wide. In industrial production, centrifugal blowers can be used for ventilation, providing fresh air for the production workshop, and eliminating exhaust gases and harmful gases. It can also be used for air supply to deliver gas to the desired location and meet the process requirements in the production process. In addition, centrifugal blowers can also be used in processes such as flue gas desulfurization, waste gas treatment, and water treatment, playing an important role.

When using a centrifugal blower, we need to pay attention to some issues. Firstly, security measures should be taken, and the electrical equipment of the blower should be regularly inspected to ensure its normal operation. Next is maintenance and upkeep, regularly cleaning the dust and dirt inside the blower to ensure its long-term stable operation. In addition, according to the specific usage environment, choose the appropriate centrifugal blower model and specifications to ensure its performance and effectiveness.
