発明の名称 (英語) SHAFT SEAL DEVICE, SEALING MEMBER AND HYDROELECTRIC POWER GENERATOR コモンズ 新技術説明会
発明の概要(英語) Provided is a shaft seal device equipped with a sealing member having excellent liquid-tightness, low frictional resistance, and high abrasion resistance. A shaft seal device provided with a sealing member, which is disposed around a shaft that is supported so as to allow rotation or reciprocation and is for securing liquid-tightness around the shaft, is characterized in that the sealing member is a porous material formed from a hydrophilic polymer resin in which the chains are cross-linked. The shaft seal device is also characterized in that: the shaft is a shaft forming a bridge between a liquid phase region and a gas phase region; and the sealing member limits leakage of liquid from the liquid phase region to the gas phase region and is impregnated with an aqueous lubricating solution prepared by adding a water-soluble thickener.
