[@originalkhawk]

Aliexpress takes anywhere between 4 weeks up to 4 months to deliver stuff to my house. i love it, because 2 weeks after i order stuff, i completely forget about it, and then out of nowhere a new package arives every week for about a month (depending on how much you order). it really feels like its christmass

[@yuxuanhuang3523]

The pump seems a sentrifugal pump. They never suck, they only push. You need a line wit no air in it, an u-shape to keep it always primed or a oneway valve to keep air getting into it from the output side (especially when the pump is off) after priming it. Any air in the pump will make it not pump.

[@comp0smentis]

lol been sick in bed but I got up so I could read text well enough to write nearly exactly this. This^^^^!! Well said.

[@Henning_S.]

Yes, a check valve will definitely work if the the pump is always filled with water, but I think it is a vane pump because you can see the input shaft is offset from the center of the casing. A vane pump is potentially capable of sucking air, but it needs to be made with pretty good precision.

I understand the love/hate relationship with aliexpress. I ordered around $80 worth of ICs for a synth I was designing and none of the ICs arrived and on top of that I didn't get my $80 back. You really have to be careful when ordering because you may think you're ordering from a company who you have previously had a good experience ,but in reality is just an unrelated company using the branding of a company with a good reputation. That being said the thing I love about aliexpress is that it's a great place to find aftermarket/obsolete/vintage ICs and very specialized tools/ test sockets/adapters. I found some very nice test sockets that would have been costed an arm and a leg on amazon and some used vintage YM2203 sound generation chips that were completely unavailable on amazon or even digikey.

Der Pumpenwirkungsgrad bei der "Drill Powered Waterpump" dürfte einfach nur extrem schlecht sein. Bei einer Höhe von 1m entsteht (unter Vernachlässigung des Schlauch-Druckverlustes) ein Höhen-Druckverlust von 990 kg/m3 (ca.) * 9,81 m/s2 * 1m, was ca. 9712 Pascal entspricht. Nimmt man den Schlauchquerschnitt bei ca. 5cm an und eine Strömungsgeschwindigkeit von ca. 3 m/s, so ergibt sich ein Volumenstrom von ca. 0,002 m3/s. Die benötigte Stutzenleistung, die an das Fluid übertragen werden muss, wäre dann ja 9712 Pascal * 0,002 m3/s = 19,4 Watt, was die Bohrmaschine ja locker leisten müsste.

Pumps often have a much smaller rating in sucting than they do in pressure. Try using a piece of threaded rod to elongate the shaft of the pump and dip it in your pond. You can than drive the pump with the drill though your rod which should provide enough pressure to pump water. Thats why water reservoirs have the pump at the bottom and it can still deliver up to 20 bar of pressure which means it can lift water up to (theoretically) 200m. No pump however can suck water from 10m as that would require absolute negative presure (-1bar) which also means perfect vacuum.

Would not recommend the drill saw, full chainsaws have numerous safety features built in which just aren't present here. If the saw kicks backs, it gets doing towards the shoulder, where there is a major artery. A regular chainsaw's handle both serves as a grip for steadying, and a physical barrier to stop the saw from reaching your shoulder on a flick back.
