Introduction: Micro Liquid Pump Sucks
The small new instructable that I propose is a suction pump, liquid that I designed to meet a requirement, I've had a few times: it is necessary to collect small amounts of liquid in places a little rough.
I used the pump you need to spray the water in the glass before you operate the car windscreen wipers, and that has a range not excessive but enough (about 1 liter per minute).I recovered from a car in demolition.
Initially I thought about battery supply, but instead I opted for a power supply with an AC/DC 12v DC output.
Step 1: The Materials and the Construction
First I closed by a tube folded and secured with wire one of two exits, since, as you know this type of pump has two outputs to feed both the crystals of the machine running now one now another depending on the polarity of the power supply.
After this I created the necessary holes in cylindrical container, then slid the pump already supplied its pipes.
I then sealed with a silicone product that I also partially filled the Interior of the container to prevent unwanted entries.
Step 2: The Switch
As regards the hermetic button I've built isolating tightly with a piece of gum attached with hot glue, the CAP previously drilled.
As you can see in the second figure of this time, I put in between the button and the rubber cover a piece of foam rubber suitably shaped to create a flexible space which enables the button return to rest position when released.
I then mounted the button and I've attached with hot glue to the desired position.
Step 3: The Connections and the Final Test
I ran and then the simple linkages, consisting in the fuel pump with 12v DC voltage through the transformer, discontinued in one of the Poles from the power button.
After that I colored with matte black spray paint which gives a more professional appearance and I accompanied all about Nice label (this of course DIY) with the logo of INSTRUCTABLES.
It remained that the testing that I promptly executed by making a video, that download in the next few days because, for some reason I don't know, I can not download it: it gives me a message like: HTTP error or IO error.
Thanks for your attention, if you have any advice for me I will accept with pleasure,
Until next time
