Abstract: PURPOSE:To judge the life of a mechanical seal by providing projected rings on the outer circumference of a rotating ring, so that the displacement of the projected rings can be detected by ultrasonic detectors from the outside of a shaft-sealing chamber. CONSTITUTION:The life measuring device for a mechanical seal comprises a vessel 1 required to be sealed, a turning shaft 2 being turned by a driving device, a shaft sealing chamber 3, a fixed seat 4, and turning rings 5 that turn together with the turning shaft 2 via a spring receiver 7, and on the outside of each of the turning rings, a projected ring 6 is provided. A compression spring 8 pushes the turning ring 5 against the fixed seat 4 for maintaining tightness. During the operation, the turning ring 5 is pushed by the compression spring 8, and the projected part of the turning ring 5 that is liable to be worn wears, and the ring is moved in the axial direction as much as the amount of wear. The ultrasonic waves emitted from a ultrasonic detector 9 hot on the outer surface of the projected ring 6 and are reflected via the sealing liquid inside the shaft-sealing chamber 3. When the turning ring 5 of the mechanical seal part wears to reach its life limit, the ultrasonic waves emitted from the detector 9 hit the outer surface of the turning ring 5 and are reflected. The difference between both reflection times is taken as the wear limit valve of the turning ring 5, thus the life of the sliding members can be estimated.
