Under the design conditions of import side channel blower, the fan with wind pressure of 30 kPa~200 KPa or compression ratio e=1.3~3 belongs to the category of import side channel blower. At present, air-ring vacuum pump is generally classified as import side channel blower in the industry. High-pressure blower, also known as high-pressure blower, is different from the general centrifugal blower. The impeller of the compressor fan (also known as centrifugal fan) is covered with a mechanical shell, and the center of the impeller is the air inlet. When the medium pressure fan works, the power equipment runs to drive the impeller to rotate, and the air is sucked in from the intake port. In the process of centrifugal fan blade rotating, dynamic action is exerted on the gas to increase the pressure and speed of the gas. Under the action of centrifugal force, the gas is discharged from the exhaust port along the blade passage. In the working process of medium pressure fan, although the impeller's rotation increases the pressure and speed of gas, the variation of gas is small, so in the design and use of centrifugal fan, gas is usually treated as incompressible fluid. The gas treatment process of the medium pressure fan is completed in the same radial plane, so the medium pressure fan is also called the runoff centrifugal fan.
Runoff centrifugal fan is the principle of runoff fan. Runoff fan is the fan of ordinary electric fan, which blows out along the direction of the fan axis. This kind of fan whose direction of outflow is in the same direction as the axis of rotation axis is called axial fan. The direction of the wind blown out by common blowers is perpendicular to the fan blade axis, so it is called axial fan. Do runoff fan. Runoff fan works by centrifugal force, so it is a centrifugal fan.
What is the function of frequency conversion in import side channel blower and cross-flow fan
What is the function of frequency conversion and the size of centrifugal fan in import side channel blower and cross-flow fan? Comparatively speaking, when the outlet of the fan is small, the air volume increases with the cross-section area of the outlet and increases by 3 pressures, and then decreases by 27. When the inlet and outlet of the fan are not connected with the pipeline, the air volume is the largest, the wind pressure is the smallest and the power is the largest.
