how to make an aquarium air pump

Hi allso i do not know much about air pumps, but i wanted to construct onei know i need a diaphgram for the pump, but what else do i need?i found this replacement part (http://cgi.ebay.com/Perfecto-Aquarium-Air-Pump-200-Replacement-Diaphragm_W0QQitemZ200197939820QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item2e9cba226c&_trksid=p3286.m20.l1116) which was the diaphragm pump itselfit has some magnet part which it attaches to for the electric part,but say i wanted to make it to a kind of attachment where i wanted it to split to two wires, how would this work?thanks!

Wanted intructable - "Convert an Aquarium Air Pump into a Vacuum Pump"

Hey all - Wanted intructable: "Convert an Aquarium Air Pump into a Vacuum Pump" I know this is pretty simple - probably... as well to add to that a mod... "Convert a Aquarium Air Pump into an Adjustable Vacuum Pump" I'm trying to build something else and would like to see how this is done - i have one shot at one Aquarium air pump and don't want to mess it up. Plus i'd like to know how to regulate the vacuum  - make it with adjustable vacuum pressure if possible - if i even really need to or at least regulate the vacuum pressure so it is not too much if it is after built. I'm sure i could do a google and find all the parts - thinik tank it out and build it... but if you know already how to do it - makes things a tad easier for me. The instrucable even easier to avoid mistakes. thanx - chase -

DC Motor Air Pump

Hello Folks! How are you? I need a air pump for my aquarium and I have tons of DC motors, I was thinking of buying one, but they are so noisy and its so much cooler to use old parts to build something. I found some projects here for water pumps using DC motors, but what I want is to build a system, using a DC motor that brings air from the outside through a small hose into my recipient, in this case my aquarium. Have you guys/gals ever heard of something like that? is it possible?

Advice on A centrifugal pump.

Hello, I recently was given a pet from a friend and after doing some research on what the little guy needs I came to the understanding that the current enclosure he is in is inadequate for his needs. Therefore, I wanted to save up some cash to get him the right size tank set up that I know he deserves. In the meantime though, I have plenty of things laying around the house that I feel could render him a more comfortable habitat till that investment goes through. After more research on the matter, I came to find that for most household aquariums, the bulk of the work falls on your filtration system. That being said, I wanted to go for a Wet / Dry Sump Filter setup as it would be  the most easiest system to setup at home with the various resources laying about. Unfortunately while gravity will be doing the work of siphoning the water from the tank down to the Wet / Dry Filter Media, it will not be moving it back up to the tank. For that I concluded there was no escaping the need of a pump in some shape or form to move that cleaner water back into the tank. From what I read the pump will pretty much determine how big I can make his tank.  So this brings me to my current dilemma. Presented with various motors around the house, I went for the biggest I could find (* excluding the water pumps in our cars mind you). That so happen to be a 1.25 HP Wet & Dry Shop vac that was collecting dust in the garage. I confirmed the motor is working and already came with the impeller attached to it. I was hoping to see if you fine folks could share some wisdom on how I can: 1.) Make it Waterproof. 2.) Adhere the right type of casing around the Impeller and Motor so as to benefit from the  Bernoulli's principle and get the most water moving through my system.  3.) I intend to have this setup not 15~20 feet from where I sleep, this motor is LOUD. I was reading online about creating a sound damping box for it and was wondering what suggestions you guys might have for that? I keep fearing there won't be enough ventilation and it will over heat. ....anything else you would like to throw in. TL;DR :

air mattress pump silencer

I have a big air mattress that I use frequently, but the electric pump is so loud that the apartment neighbors complain.  It takes 3-5 minutes to inflate, which is an eternity of noise when you're setting things up at night.   I just wondered if there might be a way to dampen the sound without having to use a foot pump or just leave the mattress inflated it at all times. Any ideas, anyone?

Air Compressor/Vacuum Pump

I have a theory: You have your supply of compressed air. You connect that by hose to one branch of a y-connector. The other branch is connected to a hose that goes into some sort of fluid that you want to move from one vessel to another. The trunk of the y is your exhaust (in theory). So now I give, say, 15 psi out of my air supply and that shoud drag my fluid out of its vessel through the y connector to the destination of my choosing. Would that work?

Amatuer experiment Contest! How high can an aquarium airpump pump water? Mini airlift pump.

I believe that many bubble pumps for aquariums can bubble the air about 2ft deep under water.  So if you use the air bubbler as part of an airlift pump, how high can you pump?  Here is a link about airlift pumps http://www.animatedsoftware.com/pumpglos/air_lift.htm (unfortunately the wikipedia airlift pump entry is commercial spam). Anyway, the aquarium air pump I used produces about 2 liters of air per minute (so not so much). So here are the contest rules.  Your airlift pump has maximum submergence of 2 ft.  You must use a T-Joint to introduce the air and you use an appropriate pipe diameter to airlift the water higher. The height pumped is measured from the top of the water in the water reservoir to the top of the airlift pipe and the submergence is measured from the top of the water in the water reservoir to where air enters the T-Joint. So, winner and Instructables world record holder is  the person who pumps water highest under these conditions. I will start with my example. Thats pretty much as high as I will go but if you have a suitable area, I think you might beat me! Competition is ongoing. Best of luck Brian

Sawdust as a medium for hydroponics? Answered

Actually I have 2 questions pertaining to hydroponics. First you should know that I have a passive hydroponic system functioning right now the container is partially submerged in a nutrient solution with holes in the bottom of the container. The medium I'm using right now is perlite to allow more oxygen and act like a wick. I do have a top layer of aquarium gravel to anchor the plant better. I've been thinking of trying to add more oxygen to the roots by using an air pump. I was going to insert the tube from the top (the dry section above the water) pointing down to the wet section to blow some air to the roots. Would this be an unnecessary addition if I continue to use perlite as a medium? My second question is the title, would sawdust work as a medium for hydroponics? I assume it would be able to act like a wick for a passive system my concern is would the roots get enough oxygen in sawdust? Also most mediums are inert sawdust wouldn't be, would that have a negative impact on my plant?

Bike pump problem?

I was using my bike pump today to fill a pneumatic launcher, and finally I just got fed up with the leaking around the pump base. On every stroke, the first 3/4 of air would be leaked out of the base, and it would only compress the remaining 1/4 of air remaining, and that would only compress if you pushed down very hard, and quickly, otherwise it all leaked out. And no matter what pressure the launcher was pressureized to, the pump handle/piston would slide down slowly, getting pushed down under it's own weight, meaning that there was almost no resistance to it. I think the leak is occuring where the tube meets the pump base, and you can feel air rush out with your legs as you pump. I'm pretty sure there is a one way valve in the gauge portion of the pump, which connects to the base with a hose,  and the filling hose is coming out of it, which is allowing me to compress at least a little air before the rest leaks out. I disassembled  the pump, starting with the base. Turns out, the leak was from an oring on the tube which was not tightened down enough by a screw on ring around the base of the tube. Put it back together, and voila, pushing my finger against the schrader valve connector and pushing down on the pump handle created pressure against my finger and no leaking. As soon as I hooked it up to my launcher, i realized something was up, I could pump down once, but the pump handle just got pushed upwards as soon as i let go. This is what I can't figure out how to fix. It seems the one way valve in the gauge portion is locked in the open position. Anybody know how to fix this? EDIT: Okay I took pictures of the pieces. I now cannot figure out if the valve is in the base, or the gauge portion, so i have included pics of both. Hopefully someone can help me figure this out. EDIT 2: Turns out the valve is in the base, and the ball just fell out when i first disassembled it, i have now found the ball and it is working fine.

Nerf Gun Valve? (Air, Need a valve)

Yea. Basically, I'm trying to make a nerf rifle with a better trigger. I've used ball valves in the past, but those let out the air way too slow, and you jerk when you pull that.  So I need some kind of valve that can be pulled, and is airtight.

Can one cool air with a bicycle pump?

Here is the thing. I'm going on a 5 day trip and I'm taking a cool box with me. A cool box will only stay cold for half a day with ice in it. Compressed gas becomes cold when it expands, but buying cans of whatever gas and releasing them in the box is wasteful and expensive. Air out of the bicycle pump is kind of cold, but not near cold enough. How can I decrease the temperature coming out of the nozzle ? Or does someone have a better idea on how to turn muscle power into cool drinks.

Can I simply connect them to a digital output and simply close the circuit somehow every time I want it to be on and turn open it when I want ti to be off? Thanks!

Air Conditioner Condensate

I've been thinking recently about ways to reuse the condensed water vapor that comes out of my air conditioner condenser. I've currently got a bucket set up under the spot where the condensate drips out just to see how much water is actually wasted. With the summer heat, I've got the AC going almost all day, and it comes out to about 1 gallon a day. What I'd ultimately like to do is have a storage tank for this water that I can use to water the lawn, wash the car, etc. The problem, though, is that the water outlet is very low to the ground, so only a small bucket will fit directly underneath (meaning it overflows by the end of the day). I'd like to have some sort of hose direct the fluid into a much larger container, and I'd like to do it without electricity. I can't think of a way to move the water without using some kind of pump, though. Any ideas?

How clouds act as an air pump to suck in air. Not how you think they do!

I have been thinking a long time about the biotic pump theory but I still don't understand it.  The math is too hard for me.   BUT it got me to thinking.   It is a point of major dispute in the meteorological world.   Does condensation cause low pressure?  2 russian nuclear physicists say yes,  almost everyone else says no!   So,  I thought and thought and thought.  Now I think I have a simple enough explanation And yes, they may not necessarily cause low pressure under the cloud (probably do)  but they definitely suck in air from elsewhere.  Imagine a fleet of huge doughnut shaped dirigible airships. They are sitting at 10,000 ft just floating there.   Now the commander tells everyone that they must now fly at 5000 ft.   So they turn on their propellers (in the hole in the doughnut) and drop down to 5000 ft by propelling air up  through the hole.   Now staying at 5000 ft is achieved by running the propellers at just fast enough.  So at 5000 ft they are pumping air from under the doughnuts to above them.   Now imagine a cumulus cloud.  Even though it is not fixed in size or shape and it does not have a propeller,  it is doing the exact same thing.  Air is being pumped up the middle and the clouds are sitting lower in the sky than they "should",  because they are sending that column of air up into the sky.   Here is my video to explain it visually.  https://www.youtube.com/watch?v=sPO8dWm_GIg

Air Compressor RPM? Answered

I found an old cast iron 50 + year old 2 stage air compressor and I was wondering what RPM's I should run it at.  My dad says it is running much slower than he remembered and it is going 323 RPM's compared to the original gear ratio that would have run at 269 RPM's.  That should be dramatically faster, so could going too fast decrease performance, or something, or is there a reason the original motor may have slowed down? The RPM's are a complete guess based upon the 1725 RPM motor average.  The only reason I had to change pullies was because the original had FLAT BELTS (awesome) from back when people cared and build stuff right.  Now I have a v-belt on it and the compressor pulley wobbles by like 2 inches and the thing is out of line, but these shouldn't be slowing it down. Basically I need to know what RPM's I should be running the compressor at. P.S.  It can double as a vacuum  pump and it uses old fashion check valves!

Has anyone made a solar heat powered Fluidyne stirling engine air pump?

So, I will start with what I have in mind.  (Might be total rubbish because I don't fully understand).  You have a solar collector box, not more than 1 meter square.  painted black 1 to 2 cm deep,   and probably with glazing over top. The box itself is metal fully closed up and the back is insulated.  From the box through the insulation there are some metal tubes that go to another box at back for the cooling chamber. Tubes are constricted so the air sprays through to the cooling box and it goes into steel wool as it expands. On the reverse stroke, it does not go so much through the steel wool because the nozel constriction is  on that side not the hot side.   Power is taken away from a liquid piston somewhere attached to both chambers  or a diaphragm at the back. (It can be water cooled). I want the strokes to be long and slow. Can it work?   Temp difference will only be around 40 degrees C and the pumped air ( 2 valves  in chamber off of liquid piston) only needs to go to 2 psi. )    I have been in contact with a guy in Germany who made Sterlings that worked with sun heat.    But he didn't use Fluidyne (also called liquid piston stirling) and he did not pump air.          My specs are extremely low, I only need 60 litres per hour of air at 1 or 2 PSI.  It would be very cool to make it from such basic materials.                 Thanks Brian
