I have to hear a noise to have an idea. However, during closing maybe water hammering could be the reason. During opening gashing, water may create sound.
Turbine is designed to run at constant rotation speed. During the operation of the turbine when the rotation speed is constant, the wicket gates will not move. The function of the wicket gates is primarily to control the quantity of water entering the turbine runner, thereby controlling power output. If the power demand is reduced, than wicket gates will reduce the amount of water proportionally to keep rotation speed constant. In the same token, when the demand increases, the wicket gates will increase amount of water passing from the turbine to keep rotation speed fixed. Secondary purpose of the wicket gate is to control the angle of the tangential velocity striking the runner bucket surface.
Love the video. Great and simple lesson on shift ring & wicket gate operation. Could do without the robot voice though (feels like I'm getting a scam call on my house phone, lol).
I was a kid out of high school and learned a lot. One night they taught me how to balance a 50 ton turbine runner. I did a couple alone, balancing them on a 6" ball bearing and adding lead weight to balance it.
On the assembly. the whole wicket gate and upper /lower rings were assembled on the shop floor. Huge stuff...the wicket gates were at least 6-7 feet high with 6" diameter shafts at each end. when it was all together we did the alignment using piano wires and a huge inside micrometer connected to a pair of headphones.
I did a google search on Allis Chalmers and find out that it was a big farming equipment and also produced equipment for mills. I have never heard this company before. What happen to the company, is it become AGRO. I never heard that one too.
Allis Chalmers , was in Lachine, Quebec Canada and built Turbines, Crushers, Vibrating Screens Ball Mills, Pumps and Compressors. I did a Machinist Apprenticeship there from 64 to 69. It has been gone for years now
I have the honor to watch the video. Thank you for publishing video
Operating the hydraulic cylinder to close or open the wicket gate. Is it need different motor? Thanks
when we opening and closing the servomotor have sound. Could you expands the sound reason?

I love your videos very much thanks you for posting them
and what is up if the rotation speed is constant?

It is a fantastic video
excellent video of this complex mechanism
Oh Hell this is good! Built these at Allis Clalmers in Lachine back in the 60's :-))
It must be fun to do something like that. I never see one close up, I envy you.

thanks for clear explanation
Thank you for your visit and support.
Very good.
Yes, it's an amazing animation vidio.
Thank you for your visit and comment. I appreciate it.
