摘要
Provided is a breakdown-predicting mechanical seal system that can detect abnormalities in sliding surfaces of a rotation-side sealing element and a static-side sealing element without influence from the area surrounding the sliding sections of the rotation-side sealing element and the static-side sealing element. The mechanical seal is an outside type, in which is sealed a high-temperature sealed fluid that may leak in the direction of the outer periphery from the inner periphery of the sliding surfaces of the rotation-side sealing element and the static-side sealing element, and is characterized in that the rotation-side sealing element and the static-side sealing element are disposed on the outside of a stuffing box, a cooling jacket is provided between the inner periphery of a housing and the outer periphery of a rotating shaft so as to prevent circulation of the high-temperature sealed fluid to the sliding surfaces, and a temperature detection means is provided for detecting the temperature of the sliding surfaces and the temperature of the sealed fluid at the inner periphery of the sliding surfaces.
