Ep3 Cheap High SCFM Air with Parallel Compressors

Тәжірибелік нұсқаулар және стиль

I need lots and lots of compressed air for sandblasting, but I'm on a tight budget and only have residential power. Let me show you how to create a rig with four compressors in parallel!
Transcript:
OK, Hi Kids! Welcome back to Hannah’s Bug!
To remove the paint and rust from my bug, I’m going to use a lot of sand blasting. Now, sandblasting requires a lot of air volume, not so much air pressure. Air pressure is measured in PSI while air volume is measured in SCFM, or Sustained Cubic Feet per Minute. You might think that I can buy, just, an air compressor with a really large tank, however, that will not work because the air tank will only supply me enough air for about 25 to 30 seconds of sandblasting and then the air compressor will need to refill the air and it’ll never be able to catch up.
For me to feel confident that I’m getting enough compressed air, I need to have 25 SCFM at 80 PSI. There aren’t many air compressors on the market today that can give me that on standard household 240 voltage. There are many on the market that can give me that on three phase power, however, on the street that I live on here in Teddyland, I can’t get three phase power off the poles.
One affordable solution would be to rent a diesel screw-type compressor. Those would really only cost my producer and camera-dog under 200 dollars a week. However, I don’t want to do all my sandblasting in one week, and to rent this over the entire course of the project would become extremely expensive, and I do not want to do that. So let me ask you a question. What would Chris Hemsworth do?
Chris Hemsworth would use multiple inexpensive compressors in parallel. Bernoulli got me these four compressors at about $140.00 each. Good boy Bernoulli! [Off-screen bark]
To run them in parallel, the air connection is actually very simple. You can see how I did them here, with more tube than 25 me’s. Yup, more. The final one. And now for the real problem: the electricity!
First, obviously, you need to make it so that each compressor is on an individual circuit because each household circuit only supplies 15 amps, while each compressor takes around nine. In simpler words, no 2 compressors in socket or else house go boom-boom!
So you’ll need to run a lot of extension cords. You need to plan this beforehand that way you get as short a run of extension cord as possible, because each foot of extension cord adds resistance to the circuit.
There are many problems to face ahead. The first problem is that reciprocating compressors have what’s called a duty cycle, which means that they’ll turn on so that they can fill their tank then take a break until it’s time to fill their tank again. Since these individual compressors are not in coordination, one of them may decide to be the hero and stay on all the time so that it burns itself out.
So I have to figure out a way to turn them all on in unison, but that will create another problem. It will create a power sag, which means there won’t even be enough current to turn them on, and they would all stall.
Each compressor has a pneumatic switch, which means the compressor will turn on when the tank is low, then turn off when the tank is full. You might just think that I can adjust these points so that the compressors are in coordination, but this won’t work, because the on and off points will change depending on the load. So I’m going to need to use electrical relays.
If these are my compressors, this will be my control, and these four will be my slaves. What would happen is, I would turn this one on, then there would be a 2 second delay before this one turns on, then another 2 seconds before this one, then another 2 seconds before this one, then another 2 seconds before the fourth slave. If I could see into the future, I would...

    Haha. I was playing around with the idea of some kind of central control to make sure one of multiple parallel compressors under independent control doesn't burn up trying to fill all the connected tanks. I did not expect to find the relevant issues so well covered by a 13 year-old! Great job. Keep it up!

    she shouldnt.... you arent supposed to run air compressors on extension cords because of the high amp draw... it can cause fires because extension cords arent usually made of the same gauge (thickness) of wire as whats in your walls... NEC (national electric code) calls for no less than 14 gauge wire in your standard 20 amp 110 outlet.... (important to note that even though the outlet itself is only capable of 15 amps the breaker is usually 20amp)..... in summary during prolonged use the extension cord wire could get so hot that it would melt the insulation off of it and cause an electrical fire.... this effect is magnified by the length of the cord.

    you do realize that a large majority of grounded extension cords sold are 14 if not 12 gauge. Unless you are buying the absolute CHEAP crappy extension cords you will be getting at a minimum 14 gauge. Also the duty cycle of the compressors will never allow the heat to reach that point in the cord or construction work would be having fires left and right from compressors running on extension cords all day while we do things like roofing or framing houses.

    Im an electrical engineer and I think this is great; keep up the good work ! The comment about a diode across the coil of the relay you are controlling with the transistor is a good one. When a relay coil turns off, it generates a voltage spike due to the energy stored in its magnetic field. This is known as a "flyback" diode.

My 62 year old brain lost track about 20 seconds in and I've decided the easiest and less expensive way is to purchase 1 60 gallon, 3HP IR compressor for about $850 and run a 240 line to it. Having run my own body shop out of my garage years ago I know it'll do almost anything I'll ever need it to do. Anyway, I guess you're about 18 or so by now and about to graduate college and take over NASA any day now so more power to you!

I see a lot of criticism and official "air compressor inspectors" up here with plenty to say what is wrong, but it's my understanding you built this with a particular mission goal in mind and I'm absolutely certain you achieved it lil lady :) (I thought I was doing good saving up for an 80gal 240v deal, now that I checked the CFM rating on all my picks knowing sandblasting is definitely part of my long term goals, I'm honestly considering two cheaper 60gal 120v deals lol, the arduino part is not a problem)

    I cannot believe the petty, insecure, and negative comments. Absolutely thrilling. This is HER solution. She invested the time to comprehend and implement. Everyone must learn somewhere. Clearly very gifted and intelligent. A note, there is a lazy solution to mechanically couple. I tracked down a US mfg that makes a phenomenal, all metal yet cheap check valve. Sellorcity on amz. I operate by pairing down into a single connection. I have two pairs of eight gallons. One mobile, and one fixed. Each pair uses this check valve joined at a T. I then have an adapter so I can run two 3/8 lines and join at the destination, or join at the pairs. Same idea. I made sure the pressure sensors cut in within a threshold. Also, drying the air is important. I recommend the check valves on quick connects so they can be oiled once every six months. I must use dedicated 15 amp circuits for each as they all synchronously cut in. I solved the frequency by pairing 7 gallon Kobalt tanks to keep mobility. I also configured the couples and check valves so I don't need every compressor on always. Not as refined, but fast and dirty. Also, check out the Makita 2HP oiled 2.5 gallon. I'm building a new array, and these peaked my interest. Taiwan made. The quality appears to be leaps over the last gen CP compressor that was very efficient. That would be the one with the crank exposed towards the handle. For performance expectations, I can run tools rated > 14 cfm.

    I admire your ingenuity, energy, and intellect, but something to consider when you are designing your stuff. The KISS principle. Back in the early days of space exploration one problem they had was ballpoint pens wouldn't write very well in outer space. The USA solved the problem with a $250, 000 (a LOT of money back then) research grant, the Russians solved the problem with a $1 mechanical pencil. Your system is subject to a lot breakdowns because of the complexity of your system. In addition the compressors are all turning on even when you are only using a small amount of air (excess power usage) and I can see where there could be a short cycling (off, on off, on) problem causing premature failure of the motors and more power wasted from the high amps pulled during repeated start ups. Probably a lot of excess noise as well at times. BTW, air systems are like electrical systems in that smaller lines have more resistance to flow, increasing the size of your airline might allow you to get by with less power or fewer compressors. Also, generally speaking, bigger compressors are more efficient. Small oiless compressors use a different tech than bigger compressors. I built 2 less complicated solutions years ago using small compressors to save space in,a mobile shop. The small units could be stuck inside the vehicles frame and take up less space, use less power most of the time, and I could use smaller, cheaper inverters. Solution A involved 2 compressors. I connected the air lines together in a common manifold and I simply adjusted the switch on one unit to kick in at a lower pressure setting (I had to scrape off the epoxy used to keep the adjusting screw in the switch from moving due to vibration, adjust the screw and epoxy it back). If the first compressor could keep up, the second compressor never kicked in. Took 15 minutes and some JB weld that already had laying around. I suppose you could readjust the cut off pressure lower also to make it cut off earlier too, but I never did. Solution B involved three compressors. All 3 had the pressure switches set up to cut off at 120psi and turn on at 90 psi in the tank (factory settings) Basically the same concept only setting the air regulators at different pressures 90psi, 80psi, and 70psi and a fourth regulator close to or at the tool to control tool pressure. On startup of the tool when the pressure dropped below 90psi the first compressor motor kicked in, if the pressure kept dropping past the regulator settings of the other compressors each would start supplying air as it reached their regulator pressure and each would start up their motor as the pressure dropped below their switch settings. You could reset the regulators, if need be, for different situations. Cheap and simple to diagnose and repair. In your situation, with the addition of some ball valves you could disconnect the compressors and use them indivdiually or any combination very quickly. With both systems, most of the time, there was only 1 compressor running, the rest was in reserve. I am sure that a hybrid of the 2 solutions would work also. Last, but not least, I would like to remind you to be careful when working with any system that can turn on automatically or can be turned on remotely by someone else. Be sure to disconnect or lock out the power. Some systems common around the house or shop are: air conditioners, refrigerators, air compressors, vacuum cleaners, blowers and fans, lights, anything that can be set on a timer or sensor, or connected to the latest danger, "the internet of things".

    In solution A, I misstated "I connected the air lines together in a common manifold ". I connected the 2 tanks together so that they acted like 1 large tank with 2 compressors feeding it. Hope it is more clear now. Solution B does have a common manifold that all tanks are hooked to but each compressor is feeding its own tank and all tanks are feeding the tool..

They also cost around $120 on sale. So for $500 she got 10 hp and 21scfm @ 90 psi. Tell me again how spending $800 on the hf 60 gallon which puts out half the power is a better idea?

    I have built and repaired many industrial controls from scratch, the few concerns i have with this is that first, you are using a wooden enclosure to store electrical components and any well designed enclosure must be able to contain a failure from a short. The wooden box is literally a fire hazard. Second it is very bad practice to mix multiple power sources that are controlled from a single board, there could be a short and jump between phases. What could be a safer and more practical solution would have been to use a small breaker panel with two 15a tandem breakers running on a 240v 30a welding circuit. This way you know that all of the components would handle a short and withstand the current. This also gives one disconnect point for safety and you don't have a risk of a cordset getting pinched or causing a hotspot with all of the plug connections. Also the idea of using the programmable chip is nice, but you could have also used a simple time delay in line with a 120v relay or even a time delay relay. These offer a easy and fast way to update your sequencing. I can appreciate a homebrew design based on things in practice, however this design should be upgraded for safety reasons and simplicity.

BTW coincidentally this is the first video I checked out and that also covered the electrical/electronic subjects. Yupperz... Perfect. Thank You Very Much.

    its brilliant but has room for a lot of breakdowns as well. 1st of all, 4 compressors that are oiless...omg, you cant possibly have neighbors or be working in the same room. 2nd is you have 36 amps load just to fill roughly 40 gals of tanks and you have 600 bucks invested plus all the extra relays and power box so lets say 700 bucks to be conservative. not to mention all the future issues with 1 relay or switch or compressor that affects everything downstream. i have sandblasted for 20 yrs so i know your situation all to well. and i tandem 2 compressors as well to sandblast simply by setting the switches cut in and out the same and run both air lines to a T and a 3rd line off the T to the blaster. i am only pulling 16 amps total load, i have 18 cfm output, and 45 gallons of air and i can run the blaster constant for over an hour and maintain 75 psi. i have 100 lb blast pot so about an hour and im out of sand anyway. and believe me, 1 hour of blasting and your ready for a break anyway. i love the theory but the KISS method is better. half the electricity, double the air volume, oh and half the noise due to mine are oil bath compressors. you also will be buying 4 more in 5 yrs or less because of no oil...both of mine are from the 1980s and still going. the only difference is you did get out cheaper on the initial investment of 700 bucks. my 2 would cost about 1000 in todays world...but i will make up that 300$ difference in power bills vs yours in 12 months or less. keep up the good work, happy blasting and if your within 50 ft of those things, in addition to the standard respirator and sandblast hood, you will also need ear protection because they are insan

Uses less amps, has more cfm, more gallons, longer yrs service and you actually have something worth something a yr from now...do a video of these 4 compressors 1 yr from now...3 of them will be replaced by then...great value! !.

    Stumbled across this video searching for "air compressor control". Creative setup, and you're awesome. You've gained a subscriber. Another option is to pick up a larger compressor pump and motor at a place like Harbor Freight. The pumps are often on sale and you can find a 5HP 240V motor surplus or scrap fairly cheap. Then mount that on your existing compressor tank. That way you don't have to deal with controlling multiple compressors, draining them, plumbing them and it will be more power efficient. I did something similar on my Campbell Hausfield (see my channel, it's in the videos somewhere) with a 5HP motor and 14 CFM (at 90 PSI) twin cylinder pump. Total investment was about $150.
