Abstract

compressor centrífugo livre de lubrificação. um dispositivo compacto de compressão de gás compreendido de: a) um ou mais compressores centrífugos; e b) um motor elétrico síncrono de imã permanente de fluxo axial de alta velocidade. o motor elétrico e o compressor são diretamente acoplados em um único eixo e suportados por rolamentos passivos magnéticos e eletrodinâmicos, livres de lubrificação. o equipamento não usa vedações mecânicas já que o rotor é colocado dentro da contenção de pressão do gás. o equipamento não requer sistemas auxiliares para refrigeração, filtração, separação ou alimentação de fluidos lubrificantes.lubrication-free centrifugal compressor. a compact gas compression device comprising: a) one or more centrifugal compressors; and b) a high speed axial flux permanent magnet synchronous electric motor. the electric motor and compressor are directly coupled to a single shaft and supported by lubrication-free magnetic and electrodynamic passive bearings. the equipment does not use mechanical seals as the rotor is placed inside the gas pressure containment. the equipment does not require auxiliary systems for cooling, filtration, separation or supply of lubricating fluids.
