压缩空气储能膨胀机进气阀严密性试验
|
摘要
目前,国内压缩空气储能电站膨胀机进气阀严密性试验所采用的试验方案、试验指标不明确,缺少对严密试验的科学论证,没有膨胀机进气阀严密性是否合格的量化指标。为准确判断膨胀机进气阀的严密性,保障压缩空气储能发电膨胀机的安全运行,文章通过对比分析火电和核电蒸汽轮机、燃气轮机进气阀严密性试验方法,结合膨胀机的结构动力特性及其运行特点,提出膨胀机进气阀严密性试验的方法,并对试验步骤进行规范,提出试验结果合格的判定标准,通过不同时间段试验的惰走时间数据进行比较,得到进气阀严密性的变化情况。该方法引入膨胀机转速作为判断依据,量化严密性试验合格指标,使试验更具客观性和可操作性,保障膨胀机的安全稳定运行。
At present,the scheme adopted in inlet valve leak test of the expander in compressed air energy storage(CAES)power station and the test parameter are not definite,the leak test lacks the scientific demonstration,and there is no quantitative index of whether the inlet valve is tight.In order to estimate the leakage of inlet valve accurately and ensure the safe running of CAES power plant,through comparative analysis on the inlet valve tightness test method of steam turbine and gas turbine in thermal power and nuclear power,in combination with the structural dynamic characteristics of expander and its operation features,this paper puts forward the inlet valve leak test method of expander and its judgment basis,and compares the idling time data of different time periods to obtain the variation of CAES inlet valve leak test.The method introduces the expander speed as the judgment basis and quantifies the acceptable index of leak test,which makes the test more objective and operable,and ensures the safe and stable operation of expander.
