Vertical double-stage permanent magnet air suspension ORC afterheat generator

Abstract

The invention relates to a vertical double-stage permanent magnet air suspension ORC afterheat generator. The generator consists of upper and lower volutes of an expander, upper and lower impellers, a generator stator system, a generator rotor system, an upper air suspension bearing part and a lower permanent magnet air suspension bearing part; the upper and lower volutes of the expander are positioned at the upper and lower ends of the generator, and are respectively fixed on the upper air suspension bearing part and the lower permanent magnet air suspension bearing part; the upper air suspension bearing part and the lower permanent magnet air suspension bearing part are respectively mounted at the upper and lower ends of a base of a generator shell; the upper and lower impellers are respectively fixed at the upper and lower ends of a generator rotating shaft of the generator rotor system; the generator rotor system is positioned at the middle part of the generator shell, and is supported by the upper air suspension bearing part and the lower permanent magnet air suspension bearing part; the generator stator system is positioned on the outer side of the generator rotor system; and an air gap is formed between the generator stator system and the generator rotor system. The generator fully uses afterheat resources, and achieves broad market prospects.

Description

technical field [0001] The invention relates to a vertical two-stage permanent magnetic air levitation ORC (Organic Rankine Cycle, Organic Working Fluid Rankine Cycle) waste heat generator, which belongs to the field of generator design and manufacture. Background technique [0002] Permanent magnetic air suspension bearing is a high-performance bearing that uses the magnetic field force generated by the permanent magnet to bear the working load of the rotor and uses the air suspension bearing as an auxiliary control bearing to suspend the rotor in the air, so that there is no friction between the rotor and the stator. Compared with traditional mechanical bearings, it has the advantages of low wear, low energy consumption, high speed, and long life. It is especially suitable for special environments such as high speed, vacuum, and ultra-clean. It is used in energy transportation, military medical treatment, aerospace robots, and waste heat power generation. And other high-te...
