Abstract
A mechanical seal has a seal ring and a mating ring that faces and slides against the seal ring and either the seal ring or mating ring is supported via a bellows on the equipment interior side of a seal cover installed on a housing, while the other rotates together with a rotational shaft; and a baffle sleeve with a roughly L-shaped cross-section is fixed on the equipment exterior side of the seal cover to guide quenching liquid to the sliding surfaces of the seal ring and mating ring, where the baffle sleeve is structurally split into a flange part and cylinder part. The mechanical seal allows for preassembly of its seal members on the stationary side, baffle sleeve, damper, and other related parts at a factory, service center, etc., in a reliable and controlled manner, requiring fewer assembly steps during onsite engineering works.
