RADIAL MAGNETIC BEARING AND STATOR INDEPENDENT AIR COOLING STRUCTURE FOR CENTRIFUGAL COMPRESSOR

摘要

A radial magnetic bearing and stator independent air cooling structure for a centrifugal compressor, comprising a housing (1), wherein a stator (2) is arranged inside the housing (1), air compressor magnetic bearing seats (3) are arranged at two ends of the housing (1), a radial magnetic bearing (4) is arranged on the housing, oblong holes (5), i.e., an electric motor air inlet hole (7) and an electric motor air outlet hole (8), are provided on the housing (1), and round holes (6), i.e., a radial magnetic bearing air inlet hole (9) and a radial magnetic bearing air outlet hole (10), are provided on the housing (1). The radial magnetic bearing and stator independent air cooling structure for a centrifugal compressor is simple in structure, is convenient to operate, can reduce the internal temperature of a machine, prolongs the service life of parts, and improves efficiency effectively.
