Abstract

a presente invenção refere-se um compressor de parafuso sem óleo que pode realizar tanto a prevenção de fluxo de um lubrificante quanto a aquisição de compressibilidade confiável. o compressor de parafuso sem óleo inclui: um invólucro 12 tendo uma câmara de rotor 150; um rolamento 22 que suporta eixos de rotação 21 de rotores de parafuso; um dispositivo de vedação de eixo 20 com uma parte de vedação de óleo 31 e uma parte de vedação de ar 60; uma lacuna de ventilação 50 posicionada entre a parte de vedação de óleo e a parte de vedação de ar; e uma passagem aberta para a atmosfera 24 que comunica um lado da atmosfera do invólucro com a lacuna de ventilação. assumindo uma área transversal aberta efetiva como sh e um comprimento estreito efetivo como lh em uma parte mais estreita 24d da passagem aberta para a atmosfera, assumindo uma área transversal de vedação de eixo como sa e um comprimento de vedação de eixo efetivo como la em uma fina lacuna na parte de vedação de ar, assumindo um valor absoluto de uma pressão negativa na câmara do rotor durante uma operação de descarga como |p2|, e assumindo uma pressão diferencial mínima na parte de vedação de óleo durante a operação de descarga como ¿pb, a parte mais estreita, a parte de vedação de ar e a parte de vedação de óleo são configuradas de tal modo que uma relação (la / sa2,5) / (lh / sh2,5) |p2| / ¿pb é estabelecida.
