hello this is mikage anyway and here is a water pump I'm going to make for my um Stirling engine this one right here I'm actually curing the glue right now because it has a hole in it but so this is gonna be the water pump and it's going to run off of the air pressure so when the air pressure goes in now it's going to pump the water so my air pressure is going to come in here and then there's going to be a diaphragm on this surface here so sandwich in between here so there's going to pull that in and out and then there's gonna and that water to me on that this side and then there'll be a check valve see on this layer and on this layer so the water goes in and out the correct way and then yeah that's about it so now I'm going to put it together some more use some silicone or something like that to seal it up real good and hopefully it'll work so I don't know but I used a I'm just using old scraps of aluminum like this scrap here and to get these nice circles like this well not really nice circles I am used a one-inch paddle bit in the drill and they're made for wood but it seemed to still work pretty good in its aluminum so it didn't seem to dull it at all so I worked pretty good okay so I just got the diaphragm glued in so it starts to dry but so yeah so the next step is to put in the check valves my execs want material I'm going to use yet but this diaphragm I'm just using a thick rubber glove it's like a chemical rubber glove or something okay so here's the check valves so it's just a little flap of the same material but I glued on here one on each side I was originally going to use some plastic or some rubber like this I think it's palm liner but I stuck a little piece on there and tried blood through it it would it was because the surface area is very great since the little hole you couldn't really blow through it very good so I figured that would not work so this seems like it should work alright so my design has a bit of a flaw see this check valve here when it opens it actually blocks this hole so I think I'm going to move this hole over so that it doesn't do that and then it should work a lot better so I'm going to do that okay so this is how I care my jb weld in like 10 minutes get it so that's hard enough to do something with it I just put on my hot plate like I don't know how hot it is but it's pretty hot I mean not hot not boiling but it's too hot to leave your hand on my brain but I just put them under a can to keep the heat in there and this jb weld probably has been on there for about 10 minutes and it's pretty hard I can't dig my fingernail into it but usually jjl takes about 24 hours to dry um so I'm speeding up the process a lot but so now all I've got to do so I move the hole over and blocked up the other hole and now all I got to do is just glue them back together and bolt it down so good doing that ok so if the way that I did it looks a little too complicated for you you need something easier you could instead of making all that check valve part which is probably the most complicated part well other than drilling using the paddle bit to drill the large area for the diaphragm you could replace all the check valve part with this which is a squirt gun on pump or water gun pump and you just take this part off and then this part is the check valve assembly so I think that the water would come in this one come out this one I'm not sure you know actually you thought sway but yeah these already have the check valves built-in it's kind of hard to do I mean the camera so there's little check valve part now I think that the check valves I made probably work better they seal better but that would work too um you could also use this for a piston pump - you could just glue your piston right on here and there you go you've got a piston pump alright so I've got it all put back together um so now it's time to test it out ok so here it is all hooked up so it runs a lot better armed with a load um at slower RPMs it pumps a lot more water so I have a my generator hooked up right now but I've got a squirt gun nozzle on it right now so that you can see how far it squirts it can squirt actually about 3 feet squaring pretty good so yeah I'll pop them on and that's it's not really it's not I'm not really sacrificing any on anyway performance with this either it seems like it I mean when you put sweetest tube the engine is beat up so I don't think it's really using much powerful engines right if I was using a piston pump it would be slowing the engine down quite a bit just to pump that water so you can see it helps it still pumps it fine up here but you when the engine is going on slower it pumps a lot more than if it still knows that so yeah that's how to make a DIY water pump for a Stirling engine it works really good so so yeah thanks for watching
