Product description
W6-51 high temperature centrifugal fan is based on the principle of kinetic energy conversion to potential energy, the use of high-speed rotation of the impeller to accelerate the gas, and then slow down, change the flow, the kinetic energy into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, and the gas flows into the radial direction through the impeller and then enters the diffuser. In the diffuser, the gas changes the flow direction to cause deceleration, which slows the kinetic energy into pressure energy. The increase in pressure mainly occurs in the impeller, followed by the expansion process. In a multistage centrifugal fan, use a refluxor to allow the airflow to enter the next impeller, creating a higher pressure.
Performance characteristics
Centrifugal fan is a variable flow constant pressure device, when the speed is constant, the centrifugal fan pressure - flow theory curve should be a straight line. Due to internal losses, the actual characteristic curve is curved, and the pressure generated in the centrifugal fan is greatly influenced by the change in the intake air temperature or density, resulting from a given intake air volume, maximum intake air temperature (lowest air density) The lowest pressure. For a given pressure and flow characteristic curve, there is a power and flow characteristic curve. When the blower is running at constant speed, the required power increases for a given flow rate as the intake air temperature decreases.
