超高温高压发电机组汽轮机轴向位移调整实践

Axial Displacement Adjustment Practice of Steam Turbine in Super High Temperature and Pressure Generator Set

2021年2月,首钢水钢能源事业部双超发电机组建成投运,设备投产以来,其间多种原因突发停机,先后3次造成主推轴瓦磨损。最为严重的一次,推力盘双面磨损,一度影响水钢自发电生产,打破煤气系统平衡,生产组织困难,一定程度上给煤气系统安全带来影响。为此,双超机组的平稳运行一方面关系到水钢公司生产经济性,另一方面关系到煤气系统的平衡和安全。

Since a super high temperature and pressure generator set(named as a double super set)was put into operation in February of 2021,it frequently stopped suddenly during its running,resulting in the wear of main thrust bearing bush for three times.The most serious one in those three times was the double-sided wear of the thrust disc,which affected Shuigang5s own electric generating,broke the balance of coal gas,made Shuigang’s production organization difficult,influenced the safety of coal gas system in a certain extent.Therefore,the smooth operation of the double super set is related to not only the economy of Shuigang’s production but also the balance and safety of coal gas.
