摘要： A tandem seal in a shaft-seal device for a high-speed rotation apparatus, including a means for feeding and discharging seal water (7) to and from a sealed space D which is between two mechanical seals (4, 5), the water feeding and discharging means being comprised of a ring-shaped feed water channel (75) that connects to a feed water path (72), a ring-shaped discharge water channel (76) that connects to a discharge water path (74), a shower ring (77) that closes openings of these feed/discharge water channels (75, 76), and a plurality of feed water holes (78) and discharge water holes (79) formed in the shower ring (77). The seal water (7) fed from the feed water path (72) to the feed water channel (75) is supplied into the sealed space D through all the feed water holes (78), and the seal water 7 inside the sealed space D is discharged from all the discharge water holes (79) to the water path (74) via the discharge water channel (76), thus suppressing pulsing phenomena of the seal water 7 occurring by its supply and circulation in the sealed space D.
摘要翻译：一种用于高速旋转装置的轴封装置中的串联密封件，包括用于向密封空间D供给和排出密封水（7）的装置，该密封空间D位于两个机械密封件（4,5）之间，水进料和排出装置包括连接到给水路径（72）的环形给水通道（75），连接到排水路径（74）的环形排放水通道（76），关闭这些给排水通道（75,76）的开口的淋浴环（77）和形成在淋浴环（77）中的多个给水孔（78）和排放水孔（79）。从供水路径（72）供给给水通道（75）供给的密封水（7）通过所有给水孔（78）供给密封空间D，密封空间D内的密封水7 经由排放水通道（76）从所有排放水孔（79）排放到水路（74），从而抑制在密封空间D中供给和循环而产生的密封水7的脉动现象。
