Deublin H SERIES STEAM AND HOT OIL UNIONS
杜博林公司H系列旋转接头

H系列旋转接头是DEUBLIN杜博林公司最营遍使用的自我支持 旋转压力接头，它特别适合于造纸，塑料和纺织工业用的蒸汽和热油接头。The H Series is DEUBLIN’S most popular self-supported rotating pressure joint, engineered specifically for steam and hot oil applications common in the paper, plastic and textile industries.

这种自我支持的设计是通过二个远远隔开的碳精石墨轴承实现，使用二个轴承可以得到更好的对中并且使负荷分布更均匀，从而减少磨损，延长密封的寿命。这种自我支持的设计特别适合于开式传动齿轮的纸机，因为在这种情况下，不可能有外部安装面，这种设计的特点是一个自我对中的球面碳精石墨对着保合金密封面，保密封材料含有高的保、铬含量，提供极好的密封面以及耐蚀、耐磨。使用金刚砂布处理可以使密封面翻新。Especially suited for open gear machines, where external mounting surfaces are not available, the self-supporting design of the H Series features two widely-spaced, self-aligning carbon graphite bearings that distribute the load more evenly, reducing wear and promoting longer seal life. The high nickel and chromium content of the Ni-Resist seals provides an excellent sealing surface and resists wear due to corrosion and abrasion. The sealing surfaces can be easily reconditioned with an emery cloth.

密封机构的设计使得碳精石墨总是处于压缩状态，而碳石墨受到压缩时比受到拉伸有高达4倍的强度，所以更能承受压力或水力的撞击，装在壳体而正好在碳石墨密封上方的二个螺旋塞(备选)，用于观察密封面磨损的情况，作为蒸汽接头用的配有旋转虹吸管的双流接头端盖上有二个玻璃视镜可以观察冷凝水 排出情况。The sealing mechanism is designed such that the carbon graphite is under compression. Carbon graphite under compression is four times stronger than in tension, so it can better withstand pressure surges and water hammering. The convex seal ring is also better suited to handle mechanical and thermal shock. Two threaded plugs (optional) in the housing located over the carbon graphite seals allow for monitoring of seal face wear.The H Series is available in either monoflow or duoflow configuration, with flanged or threaded stainless steel rotor. The end cap of the duo-flow version for steam service with a rotating siphon is available with dual sight glasses to monitor condensate flow.
