大家知道,卧式水轮发电机组是以蜗壳的垂直度(前后盖板的端面垂直度)作为安装基准的(一般不垂直度应小于0.03毫米/米),并保证下述质量要求:1.保证水轮机和发电机主轴的水平度和同心度;2、保证水轮机转轮和蜗壳的同心度;3保证轴承转动灵活.蜗壳的垂直度,可用框式水平仪测量,或垂吊钢琴线用内径千分尺测量盖板端面上下距离.下面着重谈谈如何从工艺上保证上述主要安装质量.
As we all know, horizontal turbine generator set is based on the volute’s verticality (front and rear cover end surface perpendicularity) as a mounting reference (generally not verticality should be less than 0.03 mm / m), and to ensure the following quality requirements: 1 Guarantee the horizontal and concentricity of turbine and generator spindle 2 Guarantee concentricity of turbine wheel and volute 3 Guarantee the rotation of bearing Flexible volute verticality can be measured by frame level or hanging piano line With the inner diameter of the micrometer gauge cover up and down the distance below focus on how to technically guarantee the quality of the above installation.
