Trying to FIX a Faulty 12V Air Compressor / Tyre inflator

[@mikeydk]

The fan isn't there because it would run out of air.... it is there to cool the motor and compressor cylinder down.

[@skonkfactory]

When you compress a gas, like in the cylinder, its temperature increases by the equation p1.v1 / t1 = p2.v2/t2 where p, v and t are pressure, volume and temperature. This is also why gas escaping from a pressurized cylinder is very cold- its volume has expanded immensely, so the temperature drops very low.

[@ramanjeet1111]

hahahaha .u said it

[@621ELECTRONICS]

I see some comments about JB Weld to repair what is essentially a connecting rod. While JB Weld is handy for various things, it is not strong enough to handle that. That motor spins pretty aggressively and fast, not to mention having to move the piston in the cylinder building up pressure, JB Weld simply couldn't take that abuse, would likely re-break within the first handful of revolutions. Only hope would be welding new material on and machining to fit. Not worth the effort in these units, they are dirt cheap normally and do not last long. I tore apart a few of these over the years, same fault and not worth fixing, however, in Vince's case, he had two identical units to make one work and it is content for a video, so its a win win as cheap as he got these. I wish I had I decent camera / skilled in editing videos back when I did a ton of repairs, would have made for some decent videos. I enjoy watching Vince work on stuff, he does nice videos. Oh, and from my experience, that fan is to cool that motor, as these can run for quite a while inflating a totally flat car tire, both the motor and compressor pump can get quite hot!

[@mahlapropyzm9180]

Worth knowing how simple these are inside, also why they are so noisy, overheat and are seemingly disposable. On the plus side, you still have a pretty beefy 12V motor, and LED beacon and a bunch of spares. Plus one working compressor :D

[@MrBuck295]

you should have put some grease on the moving parts when it was apart other than that I`m proud of you well done

[@vitor900000]

Since they look like they have being used a lot the reason the Rod broke is most probably for the lack of grease. Don't forget to re-grease the rod, the crank and all gears. @KPA is Kilopascals and ATM is Atmospheric pressure 101 kpa = 14,65 psi = ~1.03 kg.cm2 = ~1 atm = the pressure we live in.

[@steveaustin4118]

That would be good to watch

[@ovecka2]

Oh, and KPA on the display means Kilopascals which is an SI unit of pressure. 100 kPa = 1 bar = the pressure of 1 atmosphere

[@nathanmead140]

I didn't know that. now i do. But i will still use lbs and psi for all my tires (my silver bike uses lbs because it's old)

[@jeffbguarino]

I have never used the lights on these pumps, So I buy the pumps without the lights since they are cheaper. You should also feel air pressure when the motor is going. So the problem is in the pump for both of these. You don't need a tire to pump up , but they would be a better test of the unit.

[@Operational117]

KPA stands for kilopascals... our atmosphere has a semistable pressure of 101.325 kilopascals, or 1.01325 bars. (semistable meaning a very minute fluctuation (around 1-3%), which is one of the main reason why we have wind; high-pressure air always wants to go to a lower pressure area) A pressure higher than that means the object has a higher volume of air packed into the same amount of space (relative to the atmosphere). That is why a tire(tyre?) feels rock solid when tapped; the air literally wants to escape (and it always wants to escape to a lower pressure, in this case: the atmosphere), and it literally pushes against the rubber wall of the tire(tyre?). The same applies to a *lower* pressure (like a vacuum chamber), but this time it's the air *outside* that wants to go *in.* kg/cm2 (or rather kgf/cm2) stands for "kilogram-force per square centimeter). It indicates how much mass of air is being ejected per square centimeter of outlet (or exerted on a square centimeter of surface). The air inside a tire(tyre?) will try to escape, and if the inlet valve is open but plugged to a pump/pressure gauge, the air is going to try to move that way. That is why your pump can sense the pressure; it's not how much pressure it's emitting, it's how much pressure it senses the tire(tyre?) holds, and cuts off when it reaches that limit, so as not to overextend the pumping. Two reasons: 1. If the tire(tyre?) has too much air, it can degrade the driving experience and/or weaken the rubber. 2. If the pressure is *WAY* too high, the tire(tyre?) can burst, which can be dangerous. It also means you'll have to buy a new tire(tyre?)(this is getting tyresome...). Of course, some of what I just wrote might be wrong or slightly incorrect, but I believe most of this to be accurate enough. Anyone else are free to correct me if they find a fault in my writing. And don't get started on the tire(tyre?) debacle: I know it depends on nationality, I just want to bridge the gap, or meet in the middle, or... gah, I'm just trying to be nice to everyone! 😔

[@pcno2832]

I learned about tires bursting the hard way when I tried to inflate my bicycle tire with one of those gas(petrol) station pumps they used to have with a gauge that popped up with the reading; I didn't know at the time that such gauges read zero until you let off on the air valve so I kept waiting for it to move until the tire blew up and rendered me deaf for the rest of the day. Good thing it happened when I was too young to drive; with a car tire, I'd have been a right mess from the explosion.

[@heartcrafts3426]

WHERE ARE YOU VINCE? DON'T HOLD OUT ON ME MAN...I CAN'T GO WITHOUT MY "TRYING TO FIX" COLD TURKEY??

[@lucaspagan3576]

Get your blue mat dirty is much better then getting your carpet dirty, less cleaning.

[@pcno2832]

That's a nice pump; the auto shutoff feature is a big help. But I'm surprised at the screw-on fitting; I've never seen a pump like that without a clamp-on compression fitting, though they do sell clamp-on adapters you can fit, so you don't have to worry about loosing pressure while un-screwing the hose. The only other thing that pump lacks is a counter-rotating weighted gear to reduce the vibration, but that's not a huge deal; I put a small bungee cord on mine so it didn't dance on the pavement while in operation.

[@nathanmead140]

Mg/cm is probably a milligram (or other grams that start with the letter M) of pressure per square centimeter. And these look really easy to work on inside if something breaks so i might have to get one of these for my bike after i get a generator and a different 12 volt battery for it

[@sankyppp]

You get cheap foot-pumps at local parts shops. If a motor and a shaft is added to the piston rod, it will make a much more reliable tyre inflater. I am planning a diy.

[@welestgw]

You do a great job of always challenging yourself on a budget.

[@Mymatevince]

[@res1492]

Vince, i know you're not that stupid.... the fan is to cool the motor...it has nothing to do with drawing air in to pump it back out.

[@pulesjet]

Dang this is Amusing . Your seemingly lack mechanical knowledge reflects the modern times in our disposable world. No One knows how to work on anything these days. Everything contained within that simple compressor would have been common knowledge to most 12 year old boys while I was growing up.

[@hazardousshluud2000]

Yeah, I knew what was inside that pump, lol. I messed with lots of stuff like that as a young teenager.

[@MrKeebs]

I reached out to someone and it was confirmed he's on holiday.

[@FreeWhilly734]

I have one and it works absolutely fine but the screen always says 0 PSI so it's quite dangerous any idea what could cause that? Not sure what tells the controller what the psi in the tyre currently is.

[@chinmayjadhav9192]

Mine is just blowing it's own fuse everytime located in it's plug. It works fine if not plugged to the tyre. If plugged, it blows the fuse in next 5 seconds. Blown 3 so far. Anyone has any solution?

[@cslim3881]

When idling, the motor draws idling current. Once it is asked to pump air, motor current increases. Idling 1 Amp, running 4 amps. So increase rating of fuse or measure actual consumption. Then put in an appropriate fuse.

[@jeremydewolfe8026]

Did I just watch you admit you don’t know Morse Code? You are going to update us with a video of you learning Morse Code and then sending out a code to us right?

[@KrotowX]

Just threw out remains of ContimobilityKit inflator. Used it at first time after 9 years of riding the car where it was bundled. After few minutes of work large piston gear broke to shreds. No replacement around and no reason to replace because gearbox and piston are made from plastic anyway :( At least cannibalized the 12V DC motor, switch and wire with 12V connector. Interesting that switch too is 6A/2A 250V, but working motor demand 10A+ current poor switch begin to warm up and melt - noticed slight melting remains around middle pin. Seems this inflator was made for single use and is extreme example of cost cutting :)

[@TheSuperCyborg]

Oh, the suspense by 2:18 on whether your portable power supply will drive the compressor, or whether the compressor will draw so many amps from it that it will turn it into a puff of smoke... Release the shmooo! (Back to the video, and cheers, Vince!)

[@MyRegardsToTheDodo]

Was kind of fun when I worked at a gas station about 15 years back. We had a sign on our pressure checkers/tire inflaters that they were only for cars, but every now and then some idiots would try using them on their bikes. Most of the time that worked, but I once got out to make my rounds (empty the wastebaskets, check on the car wash and so on) to find a group of teen boys with very puzzled looks on their faces and a bike with only the rim instead of the back wheel. They were lucky they didn't hurt themselves.

They are de facto made for single use. And if it can inflate one tire without breaking, you are lucky.

Do you have JB Weld in the UK? I'm sure you have something similar. It's a two part epoxy that's SUPER strong if the material is prepped properly. I know you scavenged the broken one but something to think about using in the future for these types of fixes.

@@Mymatevince I thought it was too but it does work really rather well . Is heat resistant up to a certain temp and it claims it's hard enough that it can be milled and ground (not sure about those myself ) but for about £8 it's worth a shot for future projects. Only thing I noted with it is that if it's mixed wrong allowed to set too fast it can be brittle on the thinner parts and it's worth keying up the two surfaces you're fixing it to. Loving the vids .

Fan is to cool down the motor and gears, that piston shoud have a rubber sealing, you should clean it along with cylinder and put fresh grease because it will get hot and wear easy. I have the same compressor but without electronic gizmo parts. You will never use it for a car tire - it will die imediately (if not stright away or soon after). Use it to inflate bycicle tires, playing balls, beach matress and etc. The good compressors must contain air bottles to store reserves and don't load the motor.

Cheap pot metal construction means that these little compressors don' t last. Sadly the same cheap motors and pumps seem to be in most of these, even some of the named brands that you would expect to be higher quality. Pack it all with grease and don't run it for long periods, and you should get a little longer life out of it. The piston should have a bronze bearing on it, but the bearing is that crappy Chinesium pot metal arm, running on a steel shaft. Engineered to fail I'm afraid. Worth it for £7.99 for two though, and you get a free pressure transducer and reasonably powerful motor to play with, from the dead one.
