Patent ID: 8500129

Claim:
A slide ring seal arrangement for high circumferential velocities for sealing a liquid with low to no electrical conductivity, said seal arrangement comprising at least one pair of slide rings, one of which is installed in a rotationally immovable manner and the other of which is installed for common rotation with a rotating component; said slide rings having interacting slide faces which during operation form between them a sealing gap which seals a region of the slide ring seal arrangement which is pressurized by the fluid to be sealed in relation to a surrounding region, wherein one of the slide rings is formed substantially from a material with good electrical conductivity and the other slide ring is formed substantially from a material with low electrical conductivity; the slide ring seal arrangement is located in a dead-end circulation circuit of a rotating component which is to be sealed and is connected to a cooling system which has a filter; a dosing device, which increases the electrical conductivity of the fluid, is arranged in or connected to the circulation circuit; and the electrical conductivity of the fluid is set to a value in the range of from 3 to 500 μS/cm.
