Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a multi-stage high-pressure fan. Background Art

[0002] When the high-pressure fan is working, the power machine (mainly the electric motor) drives the impeller to rotate in the volute casing, and the air is sucked in from the center of the impeller through the air inlet. Due to the dynamic effect of the blades on the gas, the gas pressure and speed are increased, and under the action of centrifugal force, the gas is thrown toward the casing along the blade path and discharged from the exhaust port. Because the flow of gas in the impeller is mainly in the radial plane, it is also called a radial flow fan. The current multi-stage high-pressure fan is not convenient in the connection between the outlet and the pipeline, which affects the combination and disassembly of the pipeline and the fan.
