【摘要】 概述了在研的某重型燃气轮机喷嘴组油路的流量特性试验研究结果。通过构件及喷嘴组试验,确定了喷嘴组各流道尺寸,获得了喷嘴组Ⅰ、Ⅱ路共同供油时流量相互干扰的定量关系,获得了由于焊接等因素导致流量减小的定量关系。以试验数据为依据的喷嘴组通过了单管燃烧试验,各项指标均达设计标准。证明了该试验设备及试验方法的实用性、可行性和可靠性,试验数据为该喷嘴组的设计改型提供了可靠的依据。更多还原

【Abstract】 Briefly described were the results of an experimental study on the nozzle group oil-circuit flow characteristics of a heavy-duty gas turbine (National 863 Program Major and Special Item).Through tests performed on the components and nozzle groups,the dimensions of various flow circuits of the nozzle groups were determined.A quantitative relationship of flows in mutual interference in case of the first and second circuit of the spray nozzle groups jointly supplying oil was obtained.Moreover,a quantitative relationship of the decrease in flow rate caused by such factors as welding,etc.was also acquired.The spray nozzle groups designed based on the test data have passed the single-tube combustion test with various indexes satisfying the design standard.It has been proven that the test facilities and methods are practical,feasible and reliable.The test data can well provide a reliable basis for the retrofitted design of the nozzle groups.更多还原
