DEVICE FOR DETECTING ANOMAL WEAR FOR SEALING ELEMENTS AND ROTOR DEVICE

摘要

An apparatus (4) for detecting abnormal wear of a seal member (24) sliding with respect to a peripheral surface of a rotating member (22) for sealing the peripheral surface of the rotating member (22), comprising: a load ratio measuring unit (41) which is a load ratio a rotation of the rotating member (22); a temperature measuring unit (42) that measures the temperature of the sealing member (24); a gas concentration measuring unit (43) that measures a concentration of a gas discharged from the sealing member (24); and a determining unit (44) that determines that abnormal wear has occurred when it is detected that at least two of the measured values measured by the load ratio measuring unit (41), the temperature measuring unit (42) and the gas concentration measuring unit (43) after reaching a second reference value (A2, B2, C2) are below a first reference value (A1, B1, C1) as a result of a comparison of each measured value with the first reference value (A1, B1, C1) that is greater than a normal value (A0, B0 , C0) and with the second reference value (A2, B2, C2), which is greater than the first reference value (A1, B1, C1).
