摘要
为了检验某大型水电站水轮机的水力特性,进行了水轮机福伊特模型验收试验,包括尺寸检查、效率试验、出力试验、飞逸试验、空化试验、蜗壳差压试验、压力脉动试验、导叶水力矩试验、轴向水推力试验、筒阀下拉力试验等内容。试验结果表明:模型水轮机及换算得到的原型的效率、出力、空化、压力脉动、飞逸、轴向水推力、导叶水力矩、筒阀压力等性能指标均满足合同技术要求。
In order to test the hydraulic characteristics of the hydraulic turbines of a large hydropower plant the Yoith hydraulic turbine model acceptance tests were conducted ,including dimensions check ,efficiency test ,output test ,runaway test ,cavitation test ,spiral case differential pressure test ,pressure fluctuation test ,guide vane hydraulic torque test ,axial hydraulic thrust test and cylinder tensile test .T he test results show that the performance indexes of the model turbine and those converted from the prototype such as ef-ficiency ,pressure fluctuation ,runaway ,guide vane hydraulic torque ,axial hydraulic thrust and cylinder valve pressure all meet the technical requirements of the contract .
