气垫式调压室在某些特定条件下,有其显著的优点.挪威已有十座气垫式调压室,其中九座运行良好,一座因设计不当,不能运行。本文介绍了气垫式调压室设计运行原则,以及防止漏气的办法.事实证明,气垫式调压室也是安全可靠的. 我国将要修建许多巨型地下水电站以及高水头抽水蓄能电站,在这修电站上若采用尾水气垫式调压室,气压很低,更是利多弊少,值得一试. Air-cushion surge chambers have significant advantages under certain conditions. There are 10 air-conditioned surge chambers in Norway, nine of which are in good condition and one is not designed to operate properly. This article describes the principle of design and operation of air-cushion surge chamber, as well as ways to prevent air leaks. As it turns out, air-cushion surge chamber is also safe and reliable. China will have to build many giant underground hydropower stations and high-head pumped storage power station in this repair If the tail gas cushion type surge tank, the pressure is very low, it is more advantages and disadvantages less, it is worth a try.
