Gravity feed pump question

[OddsCrazyStuff]

Given the height of the top of the reservoir, so do I mean it should be no problem for the pumps to get liquid, but it dont hurt to double check.

[Hackzzila]

Does it go pump > res or res > pump?

It looks like pump > res and you should never do that.

[ThatOneRussian]

That will be a huge problem the pump needs to be under the res youre going to have to hold your pc upside down to fill it up...

[Mug]

Works the same way that a U-bend in a toilet works.

[airdeano]

yeah, you'll have problems bleeding and circulation wise..

you have no return to the reservoirs at all.

your GPU (red fittings) loop goes res>pump>GPU and nothing..

your CPU loop (white fittings) goes res>pump>RAM block>CPU>RAM block and nothing.

[Enderman]

yes it will be fine just make sure that there is fluid in both pumps before turning them on

 

and this loop is unfinished right? just want to make sure you dont forget your other pieces of tubing

[xgn]

I admire you're bending skills im not that good still practising and frustrated over mistakes but I'm getting there... slowly

also wozers thats a beefy radiator you have there on bottom

Its res to pump.

Gravity should do the job there.

I havent gotten that far yet, I just wanted to confirm that the pumps are good, so I dont need to redo anything.

[ThatOneRussian]

Its res to pump.

not if the pump is above the reservoir though

[thekeemo]

How the fuck did you do the res

[Hackzzila]

Its res to pump.

I would say no because the water will be cut off due to gravity.

no...that's not how fluid works

the top of the reservoirs is above the top of the pump

when a reservoir is filled, the fluid will get pushed past the equivalent heightin the tubing, which means that both pumps will be filled with water before being turned on

also the pumps are pullingdirectly from the bottom of each res which means no air will get into the pumps during filling as long as he keeps the res water level above the pump height

yeah but it will be fucked when he starts the pump ......

the way you have it situated that the reservoir cannot have any air in them at all.

making it a hydraulic loop (which is fine), but any air in the system, the flow will cease.

coolant in mass is weighted, but not enough to keep a pump from cavitation.

Its not finished yet, I just wanted to confirm that I dont need to change anything regarding the pumps first.

Thanks, that what I wanted to confirm. So as long as I keep the top reservoir full, I should have no problems?

[0ld_Chicken]

as long as the liquid level is higher in the res than the pumps are then you'll be fine.  you may need to tilt things a little at first to get liquid to them initially but even that wont be necessary I think.

I know the pumps need liquid to work, but as long as I open the other top port on the reservoir, so should liquid make the air go away.

[Enderman]

No, he will NOT.

Do you even understand how fluid dynamics work???

The reservoir fluid level will be ABOVE the pump height which means that every pipe below the water level will be filled with fluid, which includes the pump

yeah when he starts it the fluid on both sides will start going down and the fill wont be as fast as the pump pumps out the water. the water level will go down quickly on the pump and liquid will be to slow to fill up the pumo

[OddsCrazyStuff]

Its a PWM pump, so it runs at 40% speed on molex only, I think.

[Enderman]

what the hell are you talking about???

 

this is what happens when you fill the loop, before turning the pump on

the white circle is an air bubble

the orange arrows are the water flow

 

when the pump turns on it will suction the air bubble through the loop because of the high flow rate of the fluid

[0ld_Chicken]

it'll simply pull more water in.... unless he lets his res run dry during filling but that isn't the issue here

Agree that this is what will happen.  D5 pumps can be a bitch though to get them to stop cavitating.

Yeah

The pump will have fluid in it before it starts, and there will be an air bubble stuck there which will be hard to get out, but the loop will work and the pump wont be damaged

On full speed the D5 has a massive flow rate though so I don't think that air bubble will be a problem for long

What speed will this pump be on with molex only?
