A fan is a mechanical device that uses gas as a medium to transfer mechanical energy to the gas, thereby increasing its pressure and either suction or pressurizing the gas. What type does an air悬浮鼓风机 belong to? It can be categorized by the pressure of the gas at the fan outlet and by its working principle.
By categorizing based on the pressure of the gas at the fan outlet (not the standard quantity, but the range).
(1) Fan: Under standard conditions (0.101325 MPa, 20°C), the total pressure of the gas at the fan outlet is ≤ 0.03 MPa.
(2) Blower: The gas pressure at the blower outlet is 0.115~0.35 MPa.
(3) Compressor: Gas pressure at fan outlet > 0.35 MPa.
2. Categorized by working principle.
The impeller type is a gas compression and transportation machinery that is driven by a prime mover, causing the impeller to rotate and transfer mechanical energy to the gas, thereby increasing the pressure of the gas.
The impeller-type machinery can be divided into three types: centrifugal, axial, and mixed flow.
Centrifugal: As the impeller, installed within the housing, is rotated by the prime mover, the interaction between the blades and the gas transfers the energy output from the prime mover to the gas, which is then expelled through the outlet. This type of machinery is actually radial flow, but is conventionally referred to as centrifugal.
Axial Flow: As the impeller rotates within the cylindrical housing, its blades transfer energy to the gas, causing it to flow along the axis and then exit through the housing outlet.
Mixed flow: Gas flows both axially and radially within the blade passage. It falls between centrifugal and axial flow.
Air悬浮blowers are classified as blowers according to the gas pressure at the blower outlet, which ranges from 0.115 to 0.35 MPa. They are categorized as centrifugal blowers based on their working principle.
