Working Principle of High Pressure Blower by Xianrun Blower

In the designing, when the air pressure is between 30 KPA~200 KPA, this fan belongs to high pressure fan. Also called high pressure blower, it is different from general centrifugal fan. 

High Pressure Blowers for Smelting Furnace

When the impeller rotates, due to the centrifugal force, air move to outward and forward, thus forming a series of spiral movement. Air between the impeller blades spiraling rotates accelerately and pile the outside gas into side slot, after the air entering the side channel, it is compressed, then the air return to impeller blades and rotates accelerately again.

When the air moves along a spiral orbit and go through the impeller and the side channel, every impeller blade increases the degree of compression and acceleration. With the rotation, the kinetic energy of the gas increasing, the air pressure along the side of the channel increase further. When the air reach to the connection between side channel discharge and flange, the air is squeeze out of the blades and exhausted out of pump through the muffler.
