I’m reading The Three-Body Problem series and this contraption was mentioned in detail. However I couldn’t visualize it. Your visuals and explanation were super helpful. Thank you!
Four years of high school and a year of college, where i spent hours banging my head into my desk trying to understand how steam engines and governors work, and literately two videos, and now it all makes sense. I hate public school, they don't want you to actually learn anything. Thank you for making this video.
Thank you for this. I have difficulty in learning due to this pandemic for there is no face to face class yet just online class. Our instructors only give us something to read and it's not enough. Thank you for making educational videos like this. Love you!
I was reading What Might Cognition Be, If Not Computation? by Tim Van Gelder and He mentioned the governor. As someone far from engineering, I could understand how it works thanks to your video. Thank you so much.
A lot of people don't understand this style governor is where sayings "Balls Out" or "Balls to the Walls" came from - The only thing you didn't really show on the variable speed governor variant, is the spring that the governor must overcome to change the set speeds... My Two-Cylinder John Deere uses a very similar style in principle, but uses a leaf spring, hooked to the throttle demand lever on operator's station to pull the throttle arm open, and then when the speed exceeds the required load, the movement of the fly-weights overcomes that spring tension and shuts the throttle plates, also if you shut the lever at the Operators station it will force the throttle to idle in case of governor failure. It Idles at 350-400RPM and runs at 1050 No-Load and 975 under load. - The one you show is a more or less a "Fixed Speed Governor"
Balls to the wall comes from aviation 20th century, specifically referring to the round tops of throttle levers being pushed to the firewall of the cockpit.
I fully-understood! Your explain is easy to understand. I have trouble listening english but your pronunciation is clear to understand. I appreciate about your lecture👍Thank you!
Taking Power Engineering online, have followed your channel for quite some time. Honestly feel like I've learned more from your videos than the books, you are a blessing 🙏
Otis Elevator flyball governors are not outdated in my opinion compared to most of the newer designs. It is just a strong yet simple design. It will do its job for many years with hardly any maintenance.Just like Great Grandma's cast Iron cookware will generations later. But sales need to be made and someone needs to produce something new to kill the everlasting. In some cases, certain devices do not need to be redesigned. There is something special about things that were designed so well that they seemingly last forever and are easy to repair and/or maintain.
this is the mechanism used to control speed of the motor in Kitchenaid stand mixers. when you move the lever an actual circuit board that is pivoted off the read moves back and forth, moving it further and closer to the governor depending on which speed is selected. antique tech but ingenious
I'm thinking by adjusting the weight of the balls you could change the speed it governs to. Then I thought it would be nice to have springs forcing the arms down so that you could simply turn a nut and the speed setting would change. Then I thought, boy I'd like to figure a way to adjust that nut while the whole thing is spinning. Right now I think maybe if you could slap a thrust bearing on those arms by attaching a sleeve on a hinge so they will still be able to lift up and down then use the steam in a piston or airbag to push down on the thrust bearing all while controlling the steam pressure with a valve. That's the best I can do. Let me know if anyone has a simpler idea?
@@savree-3dThe valve opening and closing is a function of the centrifugal force, and as you explained, when the engine is 100rpm, it will be completely open, then at 200rpm starts to close, then at maximum rotation valvle will shut off. So the amount of steam (or air) going into the engine is controlled to keep constant rpm, right? Sorry I think I was mixing 'vehicle speed' and engine rpm when I asked the question.
Thank you for such a clear instruction. However, I am looking for a way to mechanically control the speed of a motor generator set, even if the load on it is changeable. For that, I require the least number of moving / wearing parts, so no horizontal to vertical gears for me, I have horizontal shafts only. I guess I could invent a system of fan paddle air brakes, with weights working against springs, to place new load on a flywheel which is starting to spin too fast, and the frequency of the generator is starting to climb out of range. I expect this may be achieved with inverter based speed controllers, but I want to cut out the electronics and come up with a simple, low tech, "flintstone" approach. I shall continue my search!
If by "mechanical governors" you mean throttle levers, linkages, cables, and throttle return springs, then yes... ALL ENGINES not just small ones use "mechanical governors." But this is a CENTRIFUGAL GOVERNOR, and anyone deploying this mechanism for a small engine would be a total idiot!
