摘要
为保证调门阀序调整后,机组调节性能及运行经济性良好,针对原高压配汽机构存在的汽门重叠度偏大,流量特性不良的问题,通过大修前的试验及计算分析,确定了合理的优化调整改进方案。改后的配汽机构特性试验表明,调节特性明显改善,机组的运行经济性得到了提高,并为一次调频特性调整改进工作创造了条件,达到了预期的目的。
<Abstrcat> Through overall test calculation and analysis on domestic large turbine matching steam devices,checking out original problem in design feature,during overhaul to adjust and modify on turbine matching steam devices,clearly to improve adjusting feature of turbine matching steam device and ecomomic profits of operation;feature test and analysis state that wish effect have been got for adjusting and modification.
