| Abstract: | The distributor of 7# unit of Xiajiang Hydropower Station adopted an interval arrangement of spring connecting rod and plain connecting rod. In the process of 7# unit testing, spring connecting rod occurred a little flex and the signal of spring confiect- ing rod action was sent. That the control ring closed too much and the guide vanes closed too fast caused this problem after inves- tigation. Through reducing compression stroke of the guide vane servomotor and adding action conditions of the segment valve, the problem that the spring connecting rod occurred flex finally was solved. |
