Centrifugal blower, as an indispensable gas conveying equipment in the industrial field, mainly relies on the clever conversion between kinetic energy and pressure energy, and this conversion process is achieved through a specific transmission mechanism.
When the centrifugal blower is started, the prime mover drives the impeller to rotate at high speed through the shaft. This transmission process is the starting point of the entire blower operation and a key link in the transmission of kinetic energy. The blades on the impeller are designed to be both sturdy and in accordance with aerodynamic principles to ensure effective capture and acceleration of incoming gas during high-speed rotation.
As the gas flows in, the centrifugal force generated by the rotation of the impeller begins to take effect. Under the action of centrifugal force, gas is thrown from the center of the impeller towards the edge, and the flow velocity increases significantly in this process. This increase in speed actually transfers kinetic energy to the gas, causing its kinetic energy to increase.
When the high-speed flowing gas leaves the impeller and enters the diffuser chamber, the flow direction changes and slows down. This deceleration process is a crucial step in converting kinetic energy into pressure energy. Through this deceleration, the kinetic energy in the gas is converted into pressure energy, thereby maintaining a stable pressure at the outlet of the fan.
It is worth mentioning that the working point of a centrifugal blower depends not only on its own performance, but also on the external system characteristics. When the resistance of the pipeline network increases, the performance curve of the pipeline will become steeper, which requires the fan to adjust its working state accordingly to adapt to the changes in the system. This adaptability is achieved by adjusting the speed or blade angle of the fan, ensuring stable gas delivery under different operating conditions.
In summary, the working principle of a centrifugal blower actually utilizes a special transmission mechanism - the conversion between kinetic energy and pressure energy. This conversion is not only efficient but also flexible, enabling centrifugal blowers to play an important role in various industrial environments and become an indispensable part of modern industry.
