Operation process and flow rate of Air Shower Blowers

- Mar 14, 2019-

In the process of operation, the Air Shower Blowers can effectively convert the kinetic energy into potential energy. In operation, the high-speed rotating impeller is used to accelerate the gas effectively, then decelerate, change the flow direction during operation, and convert the kinetic energy. A potential energy (pressure). In a single-stage centrifugal fan, gas enters the impeller from the axial direction, and the gas changes to a radial direction as it flows through the impeller, and then enters the diffuser. In the diffuser, the gas changes the direction of flow and the cross-sectional area of the pipe increases to slow the flow. This deceleration converts kinetic energy into pressure energy. The increase in pressure mainly occurs in the impeller, followed by the expansion process. In a multistage centrifugal fan, a return flow is used to bring the gas stream into the next impeller, resulting in higher pressure.

 

The air shower fan has a low gas flow rate during operation, and the pressure does not change much during operation. Generally, it is not necessary to consider the gas specific volume change during operation, that is, the gas is treated as an incompressible fluid. Centrifugal fans are available in both right-handed and left-handed versions. Front view from the side of the motor: the impeller rotates clockwise, called the right rotary fan; the impeller rotates counterclockwise, called the left rotary fan.


Air shower chamber fan is a variable flow constant pressure device. When the speed is constant, the pressure-flow theoretical curve of the fan should be a straight line. The pressure generated in the centrifugal fan is greatly affected by the change in intake air temperature or density.
