Description

Heat dissipation sound insulation high pressure positive blower

Technical Field

The utility model belongs to the technical field of high-pressure fans, and particularly relates to a heat-dissipation sound-insulation high-pressure fan.

Background

The high-pressure fan is a fan with the wind pressure of 30kPa-200KPa or the compression ratio e =1.3-3 under the design condition, the air ring vacuum pump is generally classified as the high-pressure fan, also called the high-pressure fan, and is different from a common centrifugal fan in the current industry, when an impeller rotates, a wind vane impels air to move forwards and outwards due to the action of centrifugal force, so that a series of spiral motions are formed, air between blades of the impeller rotates in a spiral accelerating way and pushes 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 way again. As the air passes through the impeller and side channels along a helical path, each impeller blade increases in compression and acceleration, and as rotation progresses, the kinetic energy of the gas increases, causing a further increase in the pressure of the gas passing along the side channels, and as the air reaches the junction of the side channels and the discharge flange, the gas is forced out of the vanes and out of the pump body through the outlet muffler.

However, when the conventional high-pressure fan is used, because the air pressure is high, great noise is inevitably generated when the fan runs, which is not beneficial to creating a good working environment for processing personnel.
