自七十年代初期气垫调压室的概念提出以来,已有9个基本无衬砌的气垫调压室在挪威投入使用。它们被用于长为13km 的引水隧洞中。其中6个自建成后运行情况令人满意,两个作了减少气损的补救工作。本文介绍至今仅在挪威才有的气垫调压室的几何形状、动态特性、运行情况及其性能。同时探讨岩石洞室的气损问题,简述两个调压室的补救工作,提出设计气垫调压室的建议。
Since the concept of air-cushion surge chambers was introduced in the early 1970s, nine basic non-shrouded air-cushion surge chambers have been put into operation in Norway. They are used in 13km long diversion tunnels. Six of these operations were satisfactory since their completion and two have made remedial work to reduce air loss. This article describes the geometry, dynamics, operating conditions and performance of an air-cushion surge chamber that has hitherto only been available in Norway. At the same time, the problem of gas loss in rock caverns is discussed, the remedial work of two pressure regulating chambers is briefly described, and the suggestion of designing air-cushion surge arresters is proposed.
