摘要： A method for detecting leakage at a fluid connection for a gas turbine fuel supply system is disclosed herein. The method includes closing a flow control valve at an upstream end of the fuel supply system and pressurizing the fuel supply system with a compressed medium via a compressed medium supply to a target pressure. The target pressure is less than a pressure threshold of a check valve that is disposed downstream from the compressed medium supply and upstream from a corresponding combustor of the gas turbine. The method further includes pointing a receiver portion of an ultrasonic detection device proximate to at least one tube fitting of the fuel supply system located between the flow control valve and a combustor which is fluidly coupled to the fuel supply system. Detection of an increase in sound level and/or the sound of popping at the tube fitting is indicative of a leak at the tube fitting.

摘要翻译： 本文公开了一种用于检测用于燃气轮机燃料供应系统的流体连接处的泄漏的方法。 该方法包括关闭在燃料供应系统的上游端的流量控制阀，并通过压缩介质通过压缩介质将压力介质加压至目标压力。 目标压力小于设置在压缩介质供应的下游和燃气轮机的相应燃烧器的上游的止回阀的压力阈值。 该方法还包括将超声波检测装置的接收器部分指向靠近位于流量控制阀和流体耦合到燃料供应系统的燃烧器之间的燃料供应系统的至少一个管接头。 在管接头上检测到声级和/或声音爆裂的声音指示管配件处的泄漏。
