BOLTR: Air Compressor Explained and Fixed.

I haven't had a compressor in the shop for a few months. So we have a look at how the compressor works and salvage good parts to build a new compressor system for the shop.

One of my first jobs out of high school was welding at Campbell Hausfeld. you were definitely right not to try to repair that. The weakness on those compressor are the heads. I'm not sure how they test them now but the 20-plus years ago I was there we tested them in a "bomb box" They were pressurize to 350 psi. When the tanks fail they always blow the heads off. The larger tanks were Hydro tested. Tanks up to 30 gallons were tested under air pressure. When one of those tanks failed it would shake the whole building. -david

[@GorillaStrengthEquipment]

AvE glad to be able to contribute. Another thing that is kind of interesting about those tanks is the large spuds that's welded in there. In order for the tank to be a certified pressure vessel you have to have inspection holes that's why some of the holes have really big bushings in them. They double as inspection holes.

[@GorillaStrengthEquipment]

krap101 not really sure what you're asking tanks under 30 gallons were tested with air pressure. larger tanks were tested with water or Hydro tested it's really interesting to watch a tank fail under a hydro. It would make a really cool video to blow that tank up with water pressure!!

[@krap101]

Gorilla Strength Equipment USA Oh, I was just wondering whether the air pressure check was a different requirement from hydro. I know most if not all high pressure gas tanks require hydro testing

[@GorillaStrengthEquipment]

krap101 At the time hydro was required one level of certification. They were trying to move smaller tanks over to hydro testing so they could increase the pressure in the tank but they were having a lot of trouble with it. The smaller tanks out sold the larger ones almost 7 to 1. Depending on the size of the smaller tanks each line would turn out 2400 tanks a shift. Hydro testing was a huge bottle neck on production. Just dumping the water from 2400 30 gallon tanks would take forever. It's been a long time since I was there but at that time 110 psi was the max pressure of the smaller tanks. I see some of them now at 175 psi. I'm guessing they are Hydro testing them. I don't recall the pressure limits and required testing for each. It's hard for me to imagine them hydro testing each of those but they may.

[@OverdrivenXR]

@ Krap101: These are low pressure. Low pressure requires only proof testing. Basically pressurize and prove it doesn't leak, distort or rupture. The manufacturer likely has an exemption/special provision to do air testing for expedience compared to draining the water and then drying the inside of the tank. The tank still experiences the same stresses as it would with water, the only difference is the vastly increased safety precautions required when using air. I intentionally ruptured a 2.5lb fire extinguisher cylinder at 900psi inside a cage and barely got wet while hydro testing it. A local dive shop had a reserve scuba tank about the same size rupture at about the same pressure. It was in a tub of water to cool it, the tub was destroyed, the wall damaged, ceiling tiles in pieces for a 8ft radius and the guy filling it couldn't hear right for hours after due to the shockwave. Hydro is way safer. High pressure is another animal. All high pressure tanks need to be hydro tested. There are certain cases where the testing interval can be extended but there are requirements for tank specification, what it contains and how often its filled. But basically all high pressure tanks require hydrotesting unless its military.

[@ethanpoole3443]

fpdiscopenguin You know, I have never jumped because of either of my compressors starting. What does make me jump every damn time is the frigging unloader valve on my 80-gallon compressor -- does it every single time and always sounds like a line or hose just busted! I do not have that issue with my wimpy little 6-gallon pancake compressor, but the 80-gallon one absolutely startles me.

[@wills.5762]

My compressor, long story short, is half a century old. I don't use it too often, but godamn when that relief valve opens up...Took out a window, once.

[@tomcardale5596]

As for "things that usually go wrong", with the single phase piston compressors I've used, I tended to get through two pump units for every one pressure switch and motor start capacitor. I've killed a lot of compressors and either I've got lucky with the centrifugal switch or unlucky with every other component, but never yet had a problem with one. Three phase compressors seem to last longer, and in my experience generally have a two stage pump instead of a twin cylinder single stage pump that the smaller single phase ones have. Where I used to work we had 4 medium sized compressors, around the 200l tank with 4-5kW motor sort of thing. Small by industrial standards but bigger than most people would have at home. We needed 3 compressors to be in use, and the 4th one was the spare that I was always fixing. The heaviest use one was around about 1200 hours per year use, but in the UK you don't seem to be able to get good quality piston compressors - they're all crap up until you spend a huge amount of money on a screw or vane compressor. In contrast, we had two (lower pressure admittedly, about 4 bar) vane compressors that had run extremely well in well over 30k hours use each. The only spare part I'd fitted was an oil pump on one of them.

[@Cafferssss]

when i was an apprentice, my boss asked me to strip a compressor to prove that i could, i fucked every single piston ring, as did the other apprentice when he did his. I spent a fortune on new parts (on company dollar mind) and re built mine proper, the other lad just left the rings out. MY boss didnt like me much and decided that the machine that was knocking its bollocks out was the one i rebuilt. So i asked him to show me which machine was bad, and to run them both. Thats where my letter stamping came into its own, i unbolted my machine and under neath was a date of repair and my name - stamped in a nice neat row. Dont know why i felt the need to share this but yeah, basically bosses are arseholes and always leave a tell tale of your work someplace incase some shit like that happens.

[@MillersMotors]

@8:00 got the capacitors mixed up! Silver is run, black is start

[@mwethereld]

As an Australian Tradesmen I can confirm this is indeed how we tag out equipment!

[@PuchMaxi]

You forgot to tell us about the unloader valve. It releases the pressure in the line, when the tank is full. That way the motor can start easier on restart and not stall out (burning up the start capacitor in the process).

[@highpwr]

He did cover the "blow off valve" = Pressure relief valve. (Safety) The valve that dumps the head pressure when the tank reaches "full" is known as the unloader because it "unloads" the pressure from the pump piston(s) & output line.

[@PuchMaxi]

Bmp, I was a little lost in translation.

[@ivanblogs]

5:56 Pretty sure THAT IS NOT A SENSE LINE - that's the unloader line. (That's where the blast of air comes from when it stops normally) Sense is the main entry on the switch base (to the diaphragm). The pressure switch is not just electric, it's a pneumatic switch as well. When the pressure is great enough, the power to the motor is switched off AND the air from between the pump and the tank check value is vented to atmosphere. This is so when the pump starts again, the cylinder isn't already under pressure - causing the electric motor to stall before it gets a chance to get some momentum. ISSUES WITH THE UNLOADER MECHANISM CAN BURN OUT MOTORS. (Particularly a problem with those single phase motors and their low torque start capacitor setups) This is why you don't turn running compressors off & on again at the power... and why the human on/off switch built operates the air & power switching.

[@PuchMaxi]

Jup, you are right Ivan! That's where the springs are for, setting the cut in and cut out pressure (hysteresis) for starting the motor.

[@keithjurena9319]

And some compressors utilize a special check valve without an unloader line to the pressure switch. Called an Air Genie, these have a spring loaded check valve that senses flow...well, all check valves sense flow..anyhow, when the pressure causes the switch to stop flow of pixies to the motor, the check valve closes to isolate the tank AND a bleed port opens to vent pressure betwixt the compressor and Air Genie. This way the compressor starts up without pressure load.

[@thetremoloco4801]

As a born and bred Aussie ave your lingo is spot on love ya vids so entertaining and informative

[@RambozoClown]

Pretty good explainin' but what you called a sense line was the unloader line. You didn't mention anything about unloading the head so the motor can start.

[@gregparker8349]

Yeah I caught that too

[@Lagggerengineering]

Glad my compressor has a 3 phase motor. That thing outlived my grandfather and will outlive me.

[@HiwasseeRiver]

As a wee laddy back in Texas I did a 3rd world fix on a propane tank. The purge was not as good as it should have been - I wouldn't call the result an "explosion" per se, more of a giant belch and fart of flame that sheared off one eyebrow , some hair and half my ginger mustache. Some how I survived my youth. Since your compressor reciprocates do you figure that was a fatigue crack?

[@ShamelessJames]

what the hell was that magic libation he sprayed on there some sort of weird clear on spray paint? went on clear and dried white. That's new to me

[@highpwr]

It's part of a crack finding kit. First you spray on a cleaning solvent to remove dirt and oil from the surface you are testing. They you spray on a red die penetrate and let it soak into the surface for a few minutes. Then wipe off the excess die from the surface. Finally you spray on a developer (goes on clear and dries to a white powder) which draws out any remaining dye that is hidden in cracks. The dye then stains the white powder showing you where the crack is. Simple, no?

[@ShamelessJames]

simple enough thanks for the explanation.

[@melaniew77msn]

That is some really helpful stuff. It is called liquid penetration dye testing. I or inspectors test some welds that I make with that same fluid. It is great for parts too large to x-ray or when hydro testing is not practical. Sometimes parts will be tested with die/pen process before being steam tested as to help keep steam testers safe. It works great to find cracks on aluminum heads or other engine parts. I general it is just really great stuff that is easy to learn to use and not to expensive. It is for more than cracks it will show any defect that is open to the surface.

[@southjerseysound7340]

[@smjones4238]

Small nylon line from check valve to pressure switch is the unloader line to drain air pressure from the line going from the exhaust valve of the compressor to the check valve when the PS shuts off, to enable zero back pressure (on the compressor) starts when the tank is at the kick in pressure. The pressure switch senses tank pressure through the fitting, usually 1/4" NPT, on its bottom. Great video as usual. Michael from Colorado

[@sharpstuffaudwayne5086]

I've got a few things with the same tag 😂😂

[@mman454]

You were right that you got the start and run capacitors mixed up. The run cap does allow a higher power factor but it does this by creating an additional offset phase, so the motor essentially runs as a two phase motor.

[@sp1nrx]

I have a shop where the compressed air tanks are inspected by the state every 5 years. I have had the same inspector everytime and he has some *very* scary stories about air tank explosions. The most memorable one involved a car wash where the air pump wore out and was consuming oil. Instead of repair or replace the pump they kept pouring oil into it. The pump was running so hot the oil caked in the HP line running into the tank (plus the tank was full of oil vapor) making a restricted orifice..... One day... BOOM! Destroyed the compressor shed, blew out a block-wall, launched the pump unit over 200 feet away, killed 1 and injured 4 people. The inspector had pictures and it was truly scary how violent it was. Mind you, it *was* a bomb but the idea that something like that can happen is sobering. I'm thinking, since this is in his house and he has a wife and child, he doesn't want to Mickey Mouse the compressor to save a couple of Canadian Pesos.... Some things are worth doing correctly. This is one of them.

[@animefreak5757]

That's why it's important to maintain your compressor, I don't think i've ever heard of a air compressor exploding that was functioning correctly, it's always overpressure that does it. After seeing his welds, yea, i wouldn't trust myself to weld a air tank either. Besides, if you have other tanks laying around, why not use em? For me, I make sure my tank stays drained, and my blowoff valve works (I test it occasionally) and don't worry too much about it. I've never heard of a air tank exploding that wasn't over pressurized, seen dozens that leak @ 125psi, but never explode.

[@marcellemay7721]

SD Customs They're fine for a small job site portable compressor up to about 4cfm. For running air nailers and stuff They're much lighter to move around and fairly inexpensive. But, for something that you're gonna park in your garage, buy the biggest thing you can possibly afford with an actual oiled crankcase. 2 stage is preferred so that you can get some real air pressure ,150-175psi, and some real cfms. I'd recommend at least a 5hp 220 volt, with a 60 gallon tank if you can afford it.

[@DrewLSsix]

SD Customs i got a craftsman 30 gal last year for $20 and the cylinder had de-chooched along with the compression ring. got a repair kit for all of $30 and sold the thing for $200. at the same time I decided to check out my many years old long suffering contractor compressor and discovered it was in immaculate condition. the rungs were the same teflon material but the cylinders were different and I think that made all the difference. the Cman was chintzy stamped metal with visible waves even in the new one, the contractor was a nice cast or pressure molded piece with a coating and it barely showed any scuffing at all where even the best sections of the C mans bore were rubbed raw. I take it then that like most things it depends on the manufacturer, oil less can be good...or it can be junk.

The white capacitor is your run cap, and the black capacitor is your start cap.The black cap has no oil to dissipate heat and is meant to be in the circuit breifly. Also a good time to check Microfared are in range.

I always did double helical screw compressors with dual evap dryers, but those were bigger shops. Every time the pressure gets low, an alternate compressor kicks on to avoid moisture in the air. Same deal with rotary vane or piston type air compressors for large HVAC pneumatic controls. We had a tank fail, and the top cap came off, went through the roof, and was never seen again. My neighbor blew the head off his compressor. It went through the roof, and came back down through another neighbor's roof. My neighbor moved out in the wee hours and he was never seen again.

I love the rotating "blue shmoo" addition to the thumbnail in the notification for subscribers.....

A little late but it's always worth it to add to the big picture. The 1/4" copper line from above the check valve to the pressure switch is not the pressure sensing, it's a mechanical bleed line to remove the head pressure and theoretically make starting the pump easier on the motor. If you want to help your motor even more add a solenoid valve and an on delay timer, 3 or 4 seconds, to bleed off the pump"s pressure to atmosphere allowing the motor time to get up to speed without the pumping load being added on top of the already high start current. This mod has proven to be a worthwhile investment and none of the compressors I've added it to since I did the first one, '74 at 70 Mile House, have fried a motor. Good day.

I do love the woodpecker approach to stick welding ,it never worked for me!

Greetings from Alberta! Thanks for the morning video ,

💯 on the tag out! If there are gentle type customers around we call it conformance failure

[@kenwolfe6093]

The run cap usually is oil filled to keep it cooler. The start cap is "dry" with a higher uf.

A rare AvE error; most of those small compressors have reed valves, not poppet valves. Keep the vijeos coming!

Your Australian is spot on good sir

[@WishIwasBrit]

always learn something - thank you sir.

[@herrwondie3857]

Man I love your videos!!! I always learn so much!! thanks for taking the time to explain how things chooch and letting us homegamers into your empire of dirt.

Love your lingo and channel peace from the uk

I'm still using an air tank from a WWII plane. Those things are almost indestructible. My Dad built our compressor back in the 60's. The compressor failed but the tank lives on.
