本文介绍了一种核电站用密封门气密性自动检测系统的研究开发及其应用。其基本原理是利用计算机高速采集密封门的密封腔内压力的变化规律,据此计算出密封门的泄漏率。此系统已经成功应用在核电站用密封门的检测中。 关键词 : 气密性 自动检测 泄漏率 Abstract:In this paper, a new auto-dectect system which is used in nuclear power plant to detect airproof gate capability is introduced. The principle of this system is that we can calculate the leak ratio of the airproof gate through detecting the change ratio of press in the cavity of airproof gate. This auto-detect system has been used in the Tianan nuclear power plant . Keywords: Airproof Capability, Auto-Dectect, Leak Ratio
