摘要
为了检验龙滩水电站水轮机模型的水力性能,进行了水轮机模型验收试验。其内容包括效率试验、飞逸试验、空化试验、压力脉动试验、轴向水推力试验、蜗壳差压试验、成像观测试验及模型水轮机通流部件几何形状及尺寸检查测量等。验收结果表明:龙滩模型水轮机性能及其换算到原型的水力性能满足合同保证要求,模型的几何型线和流道尺寸可以用于真机的设计,采购及制造。
In order to demonstrate the hydraulic performance of model turbine applied at Longtan Hydropower Project, and made the model test. The model tests include efficiency tests, runaway tests, cavitation tests, pressure fluctuation tests, hydraulic axial thrust tests, Winter-Kennedy differential pressure tests, imaging observation tests and dimensional checks. The test results showed that the prototype of the model tests meets the guarantee above the contract, and the geometry of hydraulic contours of the model can be used for prototype design, procurement and manufacturing.
