国产大功率汽轮机组高压各压力级广泛采用静叶型线为TC—1A_①、动叶型线为HQ—1的透平级。静动叶型以前都进行过详细的平面叶栅吹风试验,但缺少透平级的试验数据。从上汽厂300MW等汽轮机的实测数据来看,高压缸效率比设计值低。125MW汽轮机在机组运行的初期,感到高压缸通流部分通流能力不足,以后几经修改叶高,才使机组达到安全满发。为弄清TC—1A_①, Domestic high-power steam turbine unit pressure widely used at various pressure levels for the stator blade line TC-1A_①, moving the blade line HQ-1 level for the turbine. Static and dynamic vane type have been carried out before a detailed flat cascade hair test, but the lack of turbine-level test data. According to the measured data of steam turbine of 300MW such as SAIC, the high-pressure cylinder efficiency is lower than the designed value. In the early stage of operation of the unit, the 125 MW turbine felt that the flow capacity of the high-pressure cylinder through-flow part was insufficient, and after several modifications of the leaf height, the unit was safe and full of fire. To understand TC-1A_①,
