20080292469 | CENTRIFUGAL AIR COMPRESSOR - If the ambient temperature of a pressure volute measured by a temperature sensor exceeds 0° C., a compressor is instantly started at normal operation. If the temperature of the pressure volute measured by the temperature sensor is 0° C. or lower, there is a possibility that a rotary vane may be adhered to the pressure volute due to a congelation. Therefore, vibration along the axial direction is given to the rotary shaft by way of an axial magnetic bearing. If the vibration amplitude of the thus given vibration exceeds a predetermined value, the compressor is started at normal operation after idle operation. On the other hand, if the vibration amplitude is lower than a predetermined value, it is determined that the thus given vibration is unable to eliminate the adhesion of the rotary vane due to the congelation, and the heater is actuated to heat the pressure volute only for a predetermined time. Thereafter, the ambient temperature is detected again, and if the ambient temperature exceeds 0° C., the compressor is started, | 11-27-2008 |
