Water gun for cleaning
 

Hi there,

I saw that ppl use compressed air in soda bottles to remove dust from their computer componentes. That got me thinking, would it be possible to do a water cleaning tool this way ?

I clean my bicycle on our courtyard from time to time and there is no electricity nor waterpipe handy. So i got an idea, first clean the bike with sponge and soap, and then use watergun to remove that soap. I wouldnt need much water nor power to do that. My idea is:

Get a 20 liter ( 5 galon ) plastic container that can handle about 8 bars ( 115 PSI ), make 2 holes in it, 1 for filling it with pressure and 1 for connecting a tiny hose to it. I would connect cordless battery air compressor which can suply 8 bars to it. Now you put some water into that container and supply 8 bars of pressure then turn the air compressor off. Now i can use that water hose to remove soap from the bike and when the pressure runs out i suply more pressure to it. I could even make a 8 bar valve that would keep the container at constant pressure of 8 bars and leave the air compressor running.

Again, when i say use water hose i am talking about really small one, basicly the water coming out would be the same amount as coming out of the water gun. I wont remove dirt with it, i will remove soap. Still i think it would be better then taking a bottle of water and spilling it over the bike.

So what do you think, would it work ? Those homemade water guns i saw on youtube were mean ..

That would work although more complex then if you used a 12v pond pump in a bucket or milk jug with tubing / hose. Powered using eight 1.5v batteries for your 12v.


The battery pack could have a on/off switch for convenience

Perhaps a garden sprayer would work for you?

Much easier then my pump and battery idea.. the garden sprayer IS the answer .. imo

ecomodded: do you think pond pump will give me enough power ? Great idea though, i didnt think of that

sunspot: Thank you for this, i was sure that this thing existed, just didnt know how it is called. This is exactly what i need. I want to assembly it not buy it though and i still think battery air pump is better then pumping it yourself. The battery operating pump i am getting in few days has a max amount of 8 bars and suplys 8 liters per minute, it has a gauge also. I am thinking that this is small enough amount so that i could leave it on and spray at the same time without it filling the container with pressure to fast. I will have to play around with it but it should work. And if it wont, i can still go and buy this garden thingy

The little solar pumps can raise the water 3 meters so it will have enough force for the job
here is the specs from a common mini 12v / solar pump that I have
It cost me $5 online

Water, oil, gasoline, acid and alkali solution
Working temperature: 0 ~ 75℃
Power consumption: 4.2W
Rated voltage: 12V DC
Max rated current: 350mA
Max flow rate: 4L/MIN(1.06G/MIN)
Max Head(lift height): 3M

You can up the voltage and get them to perform stronger

After a little more thought I think a car windshield washer pump would work MUCH better for a power washer.
You can get one free from a parts car.

Great ideas but to keep it simple, would my idea work, at least for starters ? I would LOVE to make it i just need some thoughts whether it would work. I do know what at 8 bars water comes out of the hose quite fast :)

It would work Great ! imho and you get the enjoyment of making it yourself and having your plan come to volition. Also you have your air pump en route so its half way done now.. When you get it up and working I would like to see a photo or Video of it in action.


I bet it works great for you !

Have you any ideas for the pressure tank ? I was thinking one of the emergency plastic gas tanks might work , although the psi may blow the caps off .. not sure,
To provide pressure relief a 60 psi or so pressure relief valve could be used.

whats your plan for the tank ?
