Centrifugal fans and kiln fans, but what is the difference between them?
1. The latter is more complicated to install;
2. The former is often installed at the inlet and outlet of air-conditioning units, boiler drums, induced draft fans, etc. The latter is often installed in the air duct, or at the front end of the air duct outlet.
3. The former motor and the fan are generally connected by a belt driven rotating wheel, and the latter motor is generally in the fan;
4. While the kiln fan does not change the flow direction of the medium in the air duct, the centrifugal fan changes the flow direction of the medium in the air duct;
The drain shell expands slowly to slow the flow of air or gas and convert kinetic energy into useful static pressure. In addition, there are oblique flow (mixed flow) fans, the wind pressure coefficient is higher than that of the kiln fan, and the flow coefficient is larger than that of the centrifugal fan. It fills the gap between the kiln fan and the centrifugal fan. The flow is varied by changing the angle of the blades in the inlet casing upstream of the impeller. At the same time, it has the characteristics of simple and convenient installation.
A mixed flow (or axial rush flow) fan combines the features of a kiln and centrifugal fan, although it looks more like a traditional kiln fan. The enclosure can have an open inlet, but more often it has a right-angled bend shape that allows the motor to be placed outside the duct. Weld the curved plate blades on the conical steel hub.
