Detailed description of the characteristics of mixed-flow fans

Mixed-flow fans are often used in the process of industrial production, but many factories in the selection of the time do not know where to start, it is because we know too little about the characteristics of mixed-flow fans, and therefore do not know where they should be used, so we should first understand the characteristics of mixed-flow fans it.

1. mixed-flow (oblique flow) fan, wind pressure coefficient than axial fans, flow coefficient than centrifugal fans, used in wind pressure and flow are "not too big or small" occasions. It fills the gap between the axial fan and centrifugal fan. Together with the installation of a simple and convenient features.

2. Mixed-flow fan combines the characteristics of axial flow and centrifugal fans, and looks more like a traditional axial flow fan. The housing may have an open inlet, but more commonly, it has a right-angle zigzag shape that allows the motor to be placed outside the duct. The secretion housing expands slowly to slow down the air or gas flow and convert kinetic energy into useful static pressure.

3. Series low-noise energy-saving mixed-flow rotary fan is a new type of fan between axial flow and centrifugal ventilation fan, with high pressure of centrifugal fan, large flow of axial flow fan, high efficiency, good energy-saving, low noise, convenient installation, etc. Fan design is novel, compact structure, small volume, light weight, easy to install, speed less than 2000r /, noise less than 75dB (A), fan connected to the pipeline and installation in the air conditioning box, noise less than 70dB (A). Low pressure centrifugal fan, widely used in industry, civil building ventilation and dust removal, etc.

4. The fan mainly consists of impeller, casing, inlet collector, guide piece, motor and other components. The impeller is selected to have the meridional acceleration characteristics of the twisted plate welded to the hub. It is calibrated by dynamic balance and over speed test, and has outstanding aerodynamic function. The casing is round and connected with the air collector of noise elimination function to form a whole. The outlet is equipped with a flow guide, with outstanding airflow distribution and stable pressure.
