Automating 7 Lego Water Pumps

[@phantomascom]

I like that the chain pump is so slow it needs to be supplemented by the peristaltic pump. For anyone that didn't notice, the peristaltic pump's inlet can be seen at ~7:14 in the chain pump's basin (just to the left of the chain pump's left support), and the outlet can be seen at ~7:24, just below the piston pump's outlet pipe. It's a bit more obvious in the overview at 8:06. Also, centrifugal pump and external gear pump are mvps!

I remember getting that first mindstorms set you could program on your pc as a kid, it was cool but I was just lacking the knowledge to build something actually cool and inventive of course.

I really loved them, back in the day when I had Windows machines. We never had anything like FIRST here, but I totally would have done _anything_ as a kid to get into something like that. I really loved the idea of Lego Mindstorms. I know there's some kind of open-source firmware for both that makes them run some dialect of C... but it seems like extremely capable microcontroller dev boards (and for a little more, far more powerful systems-on-a-chip able even to run regular OSes like Linux, thanks to the smartphone revolution) and accessories (motor controllers, sensors, etc.) have gotten so cheap it's almost more worthwhile to 3D print an enclosure for those than to try to hack my existing Mindstorms parts to do things... hmm... I keep looking at my little Lego and junk collection cart and my 3D printer and such and wishing I had the inspiration to build something, but the past few years I've been hit by a strange inability to commit myself (or more importantly, any resources) to any project that can't be proven 'the most practical/profitable way to accomplish the objective' ahead of time. I guess I feel generally guilty or wasteful, somehow. I really wish I could get that creativity I used to have back... Maybe I should spend some time just playing with the Lego parts again...

Archimedes screw is supposed to be within a pipe, which drastically increases the volume moved with each rotation.

[@JustinShaedo]

Not in this case; it only improves flow rates by reducing loss/spillage.

[@SqueakyNeb]

​@@JustinShaedo uh, no? Putting it in a pipe effectively increases the scoop size dramatically.

[@SKOOBER.]

Through all cases we have here so far, I wish they had more accessible Lego bricks that could fulfill these thoughts

[@skilletborne]

Yes, but I don't think there would have been a way to make that with lego (although I really appreciate you sharing the information)

[@JustinShaedo]

@@SqueakyNeb Yes! You're generally right: putting an Archimedes screw in a pipe might increase the effective scoop size and thus transport rate if: 1)The edges of the scoop were (too) shallow (thus reducing overflow) 2) The end was immersed deep enough in the water; so that the 'scoop' can completely fill. 3) The spirals are tight enough relative to the angle of elevation. The scoop is not immersed deep enough, and the spirals are too loose such that in this case, enclosing it won't improve transport rates at all. Have a look at some of the images of Archimedes screws, see how they have tight spirals and the ends are submerged deep enough to take a full scoop? So we whilst actually agree on the principles here, the application differs a bit in this case... If you're starting out on learning engineering principles, respect to you, and luck on your journey, it's complicated but worth it!

[@philipweber9545]

​@@penfold7800 actually the gear pump was by far the most effective. Like the design too.

[@Torchedini]

@@penfold7800 Other pumps lack seals which doesn't help

[@CreeplayEU]

@@penfold7800 The water wheel had 22ml/s flow rate while the centrifugal pump and gear pump both had 32ml/s flow rate, not only that the water wheel is not even a pump (at least not the way he did it) and it sucks. Not only does the water wheel need 10 or 20 times more torque to do the same work depending on the wheel diameter it will also always be 10 times bigger to reach the same flow rate and to make things even worse, for the water wheel to be a pump it would need to get the water higher than the highest point of the pump, which it can't, while the other pumps are capable of at least 1 meter height if it's just the LEGO one that he made. The real centrifugal pumps are able to pump the water from 5 to 41 meters of height while the gear pumps are the same as centrifugal ones but better because they can create a lot higher amounts of pressure, that's why they are used in some hydraulic pumps which need to actually push some weight and not just pump the water. The real water wheels often require something like a river to spin the wheel which either uses buckets if you want to just get the water out of the river or if you want it to pump the water above the river it powers a piston pump, centrifugal pump or a different pump designs not shown in this video.

It might be your favorite now but when you make one and use it in real life and have it working reliably the valves will make you go crazy, they always cause problems, they're expensive to replace, they're only ideal for clean water without anything like sand, leaves etc. inside of it and they need back pressure so it's ideal to run them 24/7, not really a ON/OFF design like the centrifugal pump, gear pump or the screw pump

You can't get continuous flow from an Achmedes Screw pump unless you (pick one) enclose the screw and spin fast, use a less viscous fluid than water, remove gravity. Starting submerged will not create continuous flow.

[@ibraheemahmed1670]

The cats just vibing at the end 😂 My favorite pump is probably the external gear pump; it has such a large range and it's nice and compact. Great video as always :)

[@Dogeek]

Each one of these pumps has pros and cons in real world applications (well not every pump per se, but you get the idea). A peristaltic pump is mandatory if you want to pump liquid without the risk of contaminating said liquid (for instance, for medical reasons) A centrifugal pump offers a good balance of head pressure, with a relatively small number of moving parts, paking it quite reliable, and cheap to produce External gear pumps can have a lot of flow rate, but the head pressure is determined by the radius of the gears, it's actually very impractical in real life. Piston pumps are pretty efficient at generating even more head pressure, most of the time you see those pumps as "membrane" pumps, which work in a similar fashion, except that instead of a piston, it's actually a membrane that is moved back and forth, either electromagnetically (think like a speaker for instance) or using pneumatics.

[@radishhat5736]
