Analysis on the wide application of diagonal flow fan

The impeller of the oblique flow fan makes the air do both centrifugal and axial motion, and the movement of the air in the shell is a mixture of axial and centrifugal motion. The oblique flow fan has the advantages of high pressure, large air volume, high rate, compact structure, low noise, small volume and convenient installation. Diagonal fan is widely used in hotels, restaurants, shopping malls, office buildings, gymnasium and other civil buildings ventilation and exhaust, duct pressure ventilation and ventilation of mining enterprises. The oblique flow fan mainly consists of impeller, casing, inlet collector, outlet guide vane, motor and other components. The shell is made of a cylinder-shaped, three-section flange, the inlet is connected with the air flow pipe network, the inlet air collector is made of sword-shaped streamline, and the diagonal flow fan is made of sound-absorbing net plate, the outlet is provided with a guide piece, so that the outlet airflow has a good airflow distribution and stable pressure retention.
