分析了汽封间隙对机组振动的阻尼作用及其阻尼系数与振幅的关系。根据分析可知,汽封间隙不仅影响机组经济性,而且对机组振动也有很大的阻尼作用。
The damping effect of the seal gap on the unit vibration and the relationship between the damping coefficient and the amplitude are analyzed. According to the analysis, it can be seen that the gland gap not only affects the unit economy, but also has a great damping effect on the unit vibration.
