Abstract

The invention relates to an air suspension centrifugal blower which comprises a motor, a motor base, a flow guide opening, an air outlet, turbines and volutes. A rotor is coaxially connected with the left turbine and the right turbine through a rotor mandrel. A left radial bearing component and a right radial bearing component are disposed in a motor shell. Each radial bearing component comprises a radial bearing block, a radial bearing, a journal and a radial bearing gland, wherein the radial bearing is a foil piece type dynamic pressure gas radial bearing. An inner thrust bearing block, an outer thrust bearing block and a thrust plate are disposed on the right side in the motor shell. An inner thrust bearing is disposed between the inner thrust bearing block and the thrust plate. An outer thrust bearing is disposed between the thrust plate and the outer thrust bearing block. The inner thrust bearing and the outer thrust bearing are foil piece type dynamic pressure gas thrust bearings. The air suspension centrifugal blower has the advantages that the foil piece type dynamic pressure gas radial bearing and thrust bearings are used, the blower is good in high-speed stability, high in bearing capacity, good in lubrication performance, high temperature resistant and long in service, no external gas sources are needed, blower efficiency is increased, and energy consumption and noise pollution are reduced.

Description

[0001] technical field The invention belongs to the technical field of mechanical equipment and relates to an air suspension centrifugal blower, in particular to an air suspension centrifugal blower adopting a foil type dynamic pressure gas thrust bearing. Background technique [0002] Aeration blowers for sewage activated sludge treatment are divided into Rhodes blowers, multi-stage low-speed centrifugal fans, and single-stage high-speed centrifugal fans. Blowers in sewage treatment plants consume a lot of energy, generally accounting for more than 30%-50% of the total energy consumption of sewage treatment plants. The Roots blower is noisy and has the disadvantage of lubricating oil leaking to the cylinder. At the same time, the air volume can only be adjusted by adjusting the speed and bypassing the vent valve. The efficiency of the fan is low and the waste of energy is serious. A single-stage high-speed centrifugal fan requires a huge lubrication and cooling system, ...
