Background
The high-pressure fan is a fan with the wind pressure of 30 kPa-200 KPa or the compression ratio e of 1.3-3 under the design condition. The air ring vacuum pump is generally classified as a high-pressure fan in the current industry. A high-pressure fan, also called a high-pressure fan, is different from a common centrifugal fan, when an impeller rotates, a wind vane impels air to move forwards and outwards under the action of centrifugal force, the high-pressure fan forms a series of spiral movements, air between blades of the impeller rotates in a spiral shape in an accelerating mode and extrudes the air outside a pump body into a side groove (sucked by an air suction port), and after the air enters a side channel, the air is compressed and then returns to the space between the blades of the impeller to rotate in an accelerating mode again. As the air follows a helical path through the impeller and side channels, each impeller blade increases in compression and acceleration, and as rotation progresses, the kinetic energy of the gas increases, causing a further increase in pressure of the gas passing along the side channels. When the air reaches the junction of the side groove and the discharge flange, the gas is forced out of the vanes and out of the pump body through the outlet muffler.
