【摘要】 由于高温气冷堆采用氦气作为冷却剂,堆内构件在氦气下的摩擦学性能变化成为高温气冷堆必须研究的一个问题。在氦气环境中,材料的摩擦学性能一般要变差,而且很难采用流体润滑技术。本文讨论了粘结固体润滑膜和熔烧固体润滑膜技术在高温气冷堆控制棒驱动机构上的应用,并探讨了对于连续运转的摩擦副、固体润滑剂的几种补给方式以及固体润滑技术在氦风机上应用的必要性和可能性。更多还原

【Abstract】 Because Helium is used as coolant in High Temperature Gas-cooled Reactor(HTGR),the change of tribological properties o f HTGR structure component under Helium is a big problem.Under Heli-um,tribological properties of mate rial becomes worse and fluid lubrica tion can’t be used.Bonded solid lubr i-cation film and fusion sintering solid film are used in control rod and can solve the tribological problem well.Methods of replenishment soli d lubricant are discussed for contin uously operating friction compo-nents.The necessity and possibilit y for solid lubrication film used in Helium fan is also discussed.更多还原
