Slide ring, a shaft, a mechanical seal, a housing and a rotor for a flow machine and a flow machine

摘要

A mechanical seal includes a pair of slide rings and a spring. Each slide ring has an outer circumferential surface, an inner circumferential surface and slide or seal surfaces at one axial end. Each pair of slide rings has a rotating slide ring and a stationary slide ring, the slide or seal surfaces of each pair of slide rings being in sliding and sealing contact with each other. The inner circumferential surface of one rotating slide ring includes a device to form lock the slide ring, by direct mechanical contact to a hub or a shaft of the flow machine and at least one sealing surface at a side of the device is configured to form lock, each of the slide rings, when assembled to the flow machine supported, in an axial direction by a seal ring to one of the hub and the shaft of the flow machine.
