Abstract

PURPOSE: To achieve a high speed, reduced size device and to improve the reliability, by employing a magnetic bearing not requiring the lubrication oil while employing the shaft seal device only at one position and shortening the length of rotary shaft.
CONSTITUTION: Magnetic bearings 14a, 14b utilizing the magnetic repulsion are employed for supporting the rotary shaft rotatably. Since the lubrication oil is'nt required to be fed to the magnetic bearings 14a, 14b, enclosed structure can be employed for the magnetic bearing 14a at the high pressure stage side. Consequently no shaft sealing device is required at the high pressure stage side and it is provided only at the low pressure side where the rotary shaft 9 will penetrate the casing 6. Since the shaft sealing device 10 is required only at the suction side, the fluid in the casing 6 can be sealed completely by means of a shaft sealing device at the low pressure side, while the length of the rotary shaft 9 is shortened to make higher the dangerous speed thereby a high speed device with reduced size can be achieved.
