    摘要： A sealing device for a Lysholm compressor (23) has a carbon sealing ring (25), which is fixedly connected to the casing (3) of the compressor, and a metal maintaining ring (26), which is arranged peripherally of a shaft (5, 6, 7, 8) of a rotor (1, 2) of the compressor and rotates therewith. The sealing ring is pressed against the maintaining ring to achieve a seal. The square root of the sum of the square of the surface roughness of the sealing ring (25) and the square of the surface roughness of the maintaining ring (26) is in the range of 0.8 to 2.5 Z, which prevents the occurrence of blisters on the surface of the sealing ring and maintains the amount of oil which leaks past the sealing device below the permissible leakage level.
