    摘要： Provided is a floating ring type mechanical seal in which a floating ring is pinched and held between a rotary ring provided in a rotary shaft and a stationary ring provided in a seal casing to be movable in an axial direction while being urged toward the rotary ring so that a relative rotation of the floating ring with respect to the stationary ring is inhibited. The rotary ring is made of a sintered compact of SiC or cemented carbide. A diamond film is formed on a sealing surface sliding on the floating ring in the rotary ring. A diamond film continuous to the diamond film of the sealing surface is formed on an outer peripheral surface of the rotary ring and a rear surface, which is a surface opposite to the sealing surface, in the rotary ring.

    摘要： An abradable seal (100) is provided, comprising an outer ring arrangement (120, 150) and an energiser (140) for urging said outer ring arrangement (120, 150) against an opposing surface, wherein an outermost surface (120) of said outer ring arrangement defines a sealing surface of said abradable seal (100);
    wherein said outer ring arrangement (120, 150) is configured such that after a first period of operation said sealing surface suddenly transitions from having a relatively large surface area to having a relatively small surface area, so as to cause a sudden increase in internal leakage across the seal at said transition.

    摘要： Provided is a shaft seal device provided with a seal member which possesses excellent liquid tightness, small friction resistance and high wear resistance. In a shaft seal device which is arranged around the periphery of a shaft which is supported in a rotatable manner or in a reciprocating manner, and is provided with a seal member for securing liquid tightness around the shaft, the seal member is formed of a porous body formed by using a hydrophilic polymer resin in which chains are cross-linked. The shaft seal device is also characterized in that: the shaft is a shaft which extends between a liquid phase region and a gas phase region; the seal member is a seal member which suppresses a leakage of a liquid to the gas phase region from the liquid phase region; and an aqueous lubricant which is prepared by adding a water soluble thickening agent is impregnated into the seal member.
