摘　　要：汽轮机高中压缸在经过长时间运行后,缸体变形导致隔板与洼窝中心出现滑动间隙,设计了一种能够在满载合缸的情况下测量汽缸和隔板洼窝中心数据的多点数据测量装置,并且通过现场试验验证装置的测量效果。实际应用结果表明:该装置可以使主轴精确地按照理想角度位置静止,并且通过激光检测头精准测量间隙数据,与基准值相比,平均偏差在0.01mm以内。该装置有效缩短了测量时间,提升了调整一次到位的准确性和成功率,提高了机组的安全性和经济性。For the sliding gap between the diaphragm and the groove center caused by the deformation of the high and medium pressure cylinders body in steam turbines after a long period operation,a multi-point data measuring device that can measure data of the cylinder and the diaphragm-groove center under the full load condition with combined high and medium pressure cylinders was designed,and the measuring effect of the device was verified by field test.Actual application results show that the device can make the main shaft precisely stay at the ideal angular position,and accurately measure the gap data by laser detector head.Compared with the reference value,the average deviation is within 0.01 mm.By applying this device,the measure time is decreased effectively,the accuracy and success rate of one successful adjustment at the first time are improved,and the safety and economy of unit are improved.
