Archimedean screw water pump in action

I revisited this location 5 years later and made a follow up to this video here: • Archimedean screw wate...
This Archimedean screw water pump station is located in Wangen an der Aare, Switzerland. Its purpose is to pump water from a small stream up into a large river. this was needed because the small stream sits about 3 meters lower than the river does.

Es asombroso. Mis respetos y total admiración a todos los Ingenieros Colombianos que están haciendo este bello proyecto en el norte de Bogotá, Colombia. Están marcando historia! Lo que ya es normal en algunas partes del mundo hoy hasta ahora se construye con gran ahínco e ingeniería en nuestro bello País. Gracias Ingenier@s. Dios les bendiga enormemente a ustedes y a todos sus seres queridos. Gracias por todos sus esfuerzos y sus luchas tanto profesionales como personales. Recuerden que el lugar de trabajo es sagrado y todos sus compañeros merecen respeto. Saludos Proyecto Guaymaral en Bogotá norte; Colombia 🇨🇴. Tierra querida... Gente querida... Paz y bien.

Not a TH-cam recommendation. I actually searched for it .. Wondering such pumps exist like in my imagination!

[@jestnutz]

Me too I'm wondering if you could attach a water wheel to the crank and link it with a running stream

[@kellymoses8566]

Really inefficient. The water leaks around every flight. The flighting should be enclosed

[@wiredforstereo]

Screw pumps are very efficient, and can handle a variety of flow rates with the same efficiency. Sure, they look messy, but that is irrelevant to efficiency, only the required power vs flow matters.

[@karlnoben8199]

@Blind FreddyIndeed, when it goes up, the water doesn't fill all the flight around (to do so, you need it to be leakproof from the bottom, which needs extra bottom waterlevel control and make it more complex to maintain, for instance when something gets stuck in it). This may not be necessary as the power required to lift the water is correlated to the weight/volume of displaced water and th the difference of levels. So yes, it moves less water than with a fully enclosed pipe, put it requires proportionnally less power and is easyer to maintain

[@jjsjapp2732]

Indeed the outer perimeter has a gap line that will leak, as any atmospheric pump wil do. Some screws do have a rubber lining at the perimeter. More important is that water inside the screw should not have a higher level than the inner shaft. Otherwise water would leak over the shaft in a spiral, without making much impact to the rotor. In the atmospheric screw itself the water speed is zero. It just stands still like in an elevator, waiting while lowering, until the end is reached. Just the weight, not the speed-impact of water thrives the wheel..This is why these screw generators are much-much more fish friendly than turbines that uses pressure and high waterspeed impacts..

[@russellking9762]

would it be possible to run these on contaminated water like sewerage?

Here’s one at a wastewater treatment plant
