43、裝置模型試驗成果的匯報，察看了裝置模型試驗現場，并對葉片安放角-4。下能量特性和汽蝕特性進行了目擊試驗，經討論，現形成紀要如下：一、根據泵段模型試驗驗收紀要，本次對U20U-HL-02模型水泵進行裝置模型試驗，相關試驗標準符合招標文件要求，完成了合同規定的試驗內容。二、經查驗各測試儀器儀表率定證書原件，均在有效期內，試驗臺效率測試綜合不確定度滿足合同規定不大于士0.4%的要求各測試儀器測試位置符合有關規范要求匚三、現場測試了葉片安放角顯。的能量.汽蝕性能，觀察了模型泵的汽蝕、振動，復核測試數據與提交的試驗數據基本吻合。四、在模型裝置轉速1312.5r/min時，最優工況點葉片安放角4。、流量3
