Single Stage High-Speed Turbo Blower
The single stage high-speed turbo blower follows the compression principle of the centrifugal compressor, or dynamic compressor with radial design.
It works at constant pressure with performance depending on external ambient conditions delivering compressed air without pulsations. This is different from the positive displacement compressors working at constant flow, where the inlet air density does not affect performance and the compression is pulsating.
Air is drawn axially into the center of the impeller with radial blades and is pushed radially by means of centrifugal force. The rotation of the impeller accelerates the speed of air (kinetic energy), and forces it to pass through the downstream diffusers and volute.
Here, the high kinetic energy is converted into potential energy (pressure) slowing down the speed of the air through expansion. The velocity energy is converted into pressure energy according to Bernoulli’s principle (pressure is inversely proportional to velocity squared).
