ルシール。 In a mechanical seal that prevents leakage of sealed fluid by closely sliding a fixed ring airtightly supported on a housing and a rotating ring airtightly supported on a rotating shaft and rotating integrally with the rotating shaft. ,
An oil seal is provided on the atmosphere side of the two rings in sliding contact, the outer periphery of which is hermetically fitted and fixed to the housing, and the inner periphery lip portion that slides in contact with the rotating shaft faces away from the atmosphere side. , and a relatively high viscosity fluid is filled in a space between the housing and the rotating shaft, partitioned by both the rings and the oil seal.
A mechanical seal characterized by a sealed configuration.
