Claims

[Scope of utility model registration request]

A mechanical seal in which a stationary ring on the seal housing side and a rotating ring on the rotating shaft side are brought into relative rotational sliding contact at their sealed end surfaces, an impeller for circulating coolant is formed on the outer periphery of the rotating ring, and the seal housing, the ring On the inner periphery of
forming a cooling liquid inlet opening toward the sealed end surface and an annular groove extending oppositely along the outer periphery of the impeller;
dividing the inside of the groove into a plurality of groove portions in the circumferential direction;
A mechanical seal characterized in that a cooling liquid outlet is provided at each end of the groove portion in the direction of rotation of the impeller.
