    One way that you can mount the studs without welding is to drill and tap the studs on the tank side and then drill holes in the tank and use cap head Screws to connect them using copper washers to seal the Junction.

      @Anthony Williams Copper washers are commonly used in automotive applications typically on the oil drain plug. They are however a one time use item as they become work hardened from being clamped by the fastener. Another example of a crush able metal seal is the small washer that come on spark plugs, Which are designed to extend high heat vibration and pressure.

  • @geor664
    @geor664 Před rokem +10

    Great article on building an ultrasonic cleaner.
    Some suggestions :
    *) Positioning of the transducers under the pan.
    The two commercial units and your own show the transducers spaced equidistance and positioned relatively close to the edge of the bottom of the water tray. This will work but creates a really inefficient transfer of acoustic energy into the tray and water. The curved edge of the tray is the stiffest part of the tray. So its hard to impart vibrations into the pan. The centre of the pan is the most flexible part of the pan and this is where the transducers should be mounted.
    To maximise the amount of pan bottom-panel movement , you need to mount the transducers closer to the centre of the pan.
    You also need to keep in mind that the transducers are now acting as a broadside array (in both the X and Y directions of the pan area) and that the spacing between the transducers will affect the (spatial) phasing of them (and hence the amount of overall power). To keep the transducers working in unison (spatially) you need to space them at integers of the wavelength they operate at. The propagation velocity for water is 1450 m/s and for the steel pan , somewhere around 3000m/s ( from memory , so please confirm this before using it) Since your mounting to the metal pan, then say your transducers are running at 30kHz then 1 wavelength will be C/F = 3000/30E3 = 0.10 m (driver centre to centre). So ideally you would need to keep the transducers spaced around 100mm. Any way you have the idea , you need to plug in the operating frequency for your devices, and look up the correct propagation frequency for the metal.
    You could measure the propagation time across transducers to work out spatial phasing and ideal transducer distance by exciting one transducer (only) and measuring from a second adjacent transducer , but treating it as a "pickup microphone".
    *) Polarisation of Transducers
    It is not impossible that the output transformers feeding the transducers may have different winding directions depending on suppliers of the transformers. It is wise to check , with a scope the actual drive signal polarity to make sure all drivers are running in phase.
    *) Tuning of the driver frequency for maximum power output.
    The transducer design you are working with is known as a Tonpilz transducer ( means musical mushroom in German). The conical aluminium mounting base is a 1/4 wave acoustic shorting stub. This all means that the transducers are resonant devices meant to transfer max energy at the resonant frequency of the transducer. I suggest, you tune each of the drive and transducers, one at a time, mounted to the pan and pan full of water. Tune for maximum power transfer to the water. What I do is to float a sheet of aluminium foil on TOP of the water, and count the number of seconds to achieve pinholes. That gives you a pretty easy way of calculating a time integrated method for real acoustic power measurement. There will probably be a trimpot on each of the driver boards that will allow you to tweak the driver resonant frequency.
    *) You need to use welded lugs to secure the transducer to the pan underside
    Epoxy will work , but you lose energy ( the stuff is too compliant) and you are getting heat failure of the epoxy
    Consider using spot welding to mount the mounting studs to the bottom of the pan for maximum power transfer. If you cant afford a spot welder, using a heavy duty truck 12V battery that can crank 400 to 600Amps. Use a starting solenoid to interrupt the battery, use welding leads or car battery jumper leads ( around 1/2 inch thick copper wire) and then use a monostable multivibrator to adjust how many milliseconds to power the starter solenoid that feeds the spot weld contact points. Use a couple of spark plugs with the centre ground leads snapped off , for your point contacts.
    *) Transducer overheating
    Consider using a high temperature epoxy (electric motor coil epoxy) to glue small heat sinks to the bottom of the transducer backs , so the fans can do their job better, and place the heatsink blades in the same direction as the air flow.
    Heatsinks and glue mass will alter the Q and the resonance frequency of the transducers , so take this into account.
    If your transducers are overheating, one possibility is that they are not transferring all of their acoustic energy into the pan and water.
    As a consequence, some of the electrical energy is converted to heat in the transducer. Use this knowledge to help you tune your device for max power transfer into the water.
    *) Power transistor ratings
    Your output transistors are FeiHong FHA13009A (or similar brand) rated at 400V 100W 12A 4MHz +150℃@(Tj) in a TO-3PN flat pack
    (PNP power transistor).
    Consider uprating these , use Mouser selection search to find a suitable VCE, power, current and temperature rating. To widen your search allow for other mounting considerations such as TO3 can and use a heatsink placed in the fan air flow, and use fly leads to connect the trannies to the PCB.
    I found 2N6609 (TO3 can ) with 16A , 150W , 200 c (Tj) but a VCE of 140V ( you will need to measure the max VCE of you drivers to see if this is high enough. )
    You should measure the operating temperature of the existing trannies to see if its overheating the mode of failure or over voltage transients.For the former, you can solve using bolt on heatsink and for the latter , use a GMOV varistor across the C & E to clamp any bad transients (you will need a high speed scope to see glitches. A low speed scope may not be able to see them, and the scope leads may also be a source of damping, so beware )
    Good article - well done
    Hope this helps

  • @TheOriginalEviltech
    @TheOriginalEviltech Před rokem +84

    Thanks for making this video! Some issues i have with it are the 2 devices you called voltage stabilizers - those are bipolar transistors. The epoxy you used - the manufacturers use special high temperature high hardness homogenous mix that seems to hold the transducers even after getting over 200 deg C. The transducers are actually piezoelectric resonators and the driver boards attempt to resonate them at their own frequency. Using one driver board for 2 transducers reduces the vibration amplitude. The transformers use a special type of wire to fall in line with the skin effect at this kind of frequencies so be mindful when rewinding them. The transducers run on 1.5 up to 3 KV so be very careful with their wiring. I work with transducers for ultrasonic welding at 15, 18 and 20 KhZ with up to 3KW of power each. Be mindful when taking them out of circuit when hot and attempting to touch them when they cool off - due to the piezo effect and the plates being compressed by a large diameter bolt which contracts and expands with heat the plates can and will generate a substantial charge on the middle electrode if not in circuit. Disassembling them will also generate that type of charge as well as assembling them. The piezo electric material that the plates are made of usually contains lead and titanium but the lead is quite toxic so wear a respirator if you notice a broken plate in any of the transducers. As you found out - every board and the vat should be grounded. The polarity of the transducers is important because their outside electrode must be grounded to the vat and supply ground.

      @Carl Mayo with the correct flux, yes. Surfaces need to be very clean and heat controlled carefully to not burn out the flux. Stainless is very easy to overheat, since it is such a bad conductor of heat, so go light on the heat and give it time to come up to temperature. Harris does make a special stainless steel liquid soldering flux that is probably better for more critical or difficult to clean assemblies, but I believe the normal stay clean flux should work if the surfaces are cleaned thoroughly. Stay silv 45 or 56 brazing filler is also an alternative that can be done with a swirl tip mapp torch, but those rods are very expensive. The stay brite 8 would probably work just fine as long as you get a good clean bond.

    Bruce, I have a suggestion for you. The studs that come with the transducer heads can also be silver brazed in place. A small propane torch can generate more than enough heat for that purpose. If you carefully apply heat to the stud a little at a time it is as easy as soldering. Granted the temperature is much higher than soldering but you will see the flux melt and flow when the temperature is high enough then the silver will flow just like solder does.

      @@BranchusCreations Hey Bruce, since the tubs are thin they will warp pretty easily if too much heat is applied. First, use something like a scotch bright pad or the like and Isopropyl alcohol to clean the area you are going to braze too. Then wrap the stud in something like baling wire to hold it upright and in place with the threaded tip up and the flat against the tub. This will keep your hands clear of the heat and ensure the thing stays put. Then make a ring of the brazing wire to wrap around the unthreaded end of the stud. Next, apply a small dab of borax/flux to the spot. Remember the silver brazing metal is going to follow wherever the flux goes so start with a small dab maybe 5mm dia. or just a bit bigger than the diameter of the stud. Now place the ring tight around the stud and sit both in the borax/flux. Then heat the stud until the borax/flux melts and then until the ring melts and flows under the stud. There should be more than enough heat transferred through the stud to heat the tub. At that point you will see if the braze has stuck to the stud and the tub, it will resemble a good solder joint. Only Much hotter! ;-) Don't try and feed the brazing wire as you would solder as the torch will melt it quickly and you run the risk of pushing the stud out of place. I hope this helps.

    Just a small hint. The lugs with the threads which should be welded on the tub, to which the transducers have to be glued, have a purpose.
    The thickness of the glue needs to be a certain thickness to optimize the energy transferee from the transducer to the tub. Otherwise the energy stays in the transducer an gets converted to heat. The waste product of the energy converging world.
    If one cannot weld there are mettle stripes of different thickness which can be bought and uses to make the glue the right thickness.

      yeah that is true, but in reality glue has no business being anywhere near the transducers and the tub. Glues are organic and do not have the high density to properly transfer the phonons from the transducer to the tub. Welding is necessary otherwise you are robbing yourself on efficiency, and probably shortening the lifespan of your transducers. I was using these things way back in 1997 in combination with a Malvern Zeta sizer and a Malvern Mastersizer for particulare anaysis in the functional foods industry. Laser particle analysis, Mie theory, Fourier transform the whole shebang.

    Would be an interesting and rather cheap experiment to do a series of the aluminium foil tests with a cascade of foils hung from above, that way you could make a 3d map of cavitation intensity. I'd guess the positioning of the transducers is crucial, combined with various driving frequencies you get interference patterns with unwanted hot spots and dead zones. Though I'm almost sure you can't precisely (if at all) set the frequency of each driver, so this could easily turn out to be a futile attempt to synchronize them in the first place. Still, it would be interesting to see if any pattern emerges in the current configuration.

With the balance control set in the center, you will not have any real bass. Turning the balance all of the way to either full left or to full right will bring the bass response back to life. With the balance set in the center, one speaker is essentially moving outward on bass notes & the other is moving inward. I used to call this the Star Trek "Matter verses Anti-Matter" effect.

Drill a hole about half the diameter of the slug in the tray, then place the slug against the bottom of the tray, covering the hole, and weld from the top of the tray to fuse the rim of the hole to the top of the plug. Keep the welding gun toward the center of the hole to keep from blowing out the bottom of the tray, and work in short bursts, around 0.75-1 seconds, overlapping the end of the last burst and the start of the next slightly to maximize the chances it stays watertight. Should get that nice and firmly affixed without too much fuss.

    Protip on the whole welding thing:
    In a situation like this you don't actually need much skill to do it right. Just centerpunch the spot where the threaded bolt thingy is gonna be (so you have it marked from both sides). Then place it down right there and maybe hold it in place with some aluminium tape (or any other heat resistant tape). Then simply weld right on the spot from the other side (probably works best with a TIG welder, but MIG should work as well). You WILL blow a hole into your thin sheet metal, yes, but since the bolt is right there anyways that's actually what you want. It'll weld right through and onto the bolt. Done.

So a physical coupling to the tank is necessary especially if you use it often.

It could have a situation you envision ... though it would be pretty hard to pull it off even if you tried. You perhaps are thinking about optimizing the location ... which would decrease the weak spot near the bottom ... the optimized difference would be small ... not really worth considering it would be something like comparing 10^6 to 10^8. With a coherent single source through multiple slits, it's a bit easier to get to where you are interested ... sorta like a dbl slit with 2 rows of 4 instead. But the medium is nothing like air and the container is nothing like an atmosphere or a big pond. The container also couples well across sources although nothing like a coherent source.

      Typically for more delicate items, higher frequencies work better. You can maintain the same watt density while reducing effective power per cavitation bubble. This has 2 benefits in that's it's less likely to cause damage and it's more likely to create cavitations that will clean rather than deform. It's like using a brush with thick vs thin bristles while using the same force. You can still use 40KHz, but higher frequencies do tend to work better.

    Wiring the transducers must be done properly. The center lug is isolated from the shield shell/cone, while the other side is not. Thus the need to ground the tub itself. Before wiring, I always check 1) to see if one if the lugs shorts to the shield/cone, and 2) if the positive of negative wire from the driver connects to ground. If you wire incorrectly, the transducer will not operate, and worse, you've shorted out the driver output.

JB Weld cures into a very hard, strong, temperature tolerant, but very brittle layer that will be pulverized by the vibration over time. Epoxy has to be mixed vigorously, and contrary to what you hear, it requires a long curing time (several days) minimum. It also needs a LOT of mixing in the smallest cup you can get away with, preferably a small cough syrup cup. Too large of a cup will make it harder to incorporate the epoxy components completely and evenly. Epoxy likes to be mixed deep rather than wide so it can continually fold in on itself like cake batter. Mix about 3/4 of the cup full for a good mixing depth. I borrowed a few plastic Twizzler sticks from my local Starbucks and chucked one into my drill and stirred it at full blast for two minutes. The color should change after a good mixing.
    Second, your application of the epoxy wasn't properly applied. You glued the studs and then glued and screwed on the transducers. If you're not going to weld or braze it on, epoxying it separately won't work. Instead, screw the studs on the transducer so it's flush with the top of the horn. Abrade both the contact area and the horn itself and clean both surfaces with acetone. Add a thin layer of epoxy to both mating surfaces and press the horn firmly on the mating surface until you get a nice bead of glue around the horn. Add some weight to the horns to give it the best chance of adhering. I noticed you feared squeezing out too much glue. This was a mistake since a thick layer of epoxy reduces the cavitation and takes longer to cure. This may explain the electrical issues, for the same reasons you don't run them dry.
    Alternatively, stainless steel can be easily brazed. Make sure you buy silver solder and a good liquid flux intended for stainless steel. You can use a torch to braze the stud in place. After cleaning up and abrading the surface and adding the epoxy, screw it tightly to maximize contact.

      Can ultrasound be used to facilitate mixing epoxy or paint?

      @@JohnVallevikGreen I'm not sure, but if I were to guess, epoxy is rather viscous making it more difficult for the waves to penetrate. If it does have an effect, it would take quite a bit of time in which the epoxy has already started to set. I'm also not sure about paint, but I guess it would work as it's less viscous. I would air on caution as paint often contains volatile solvents.

      With epoxy I thought to stir mix manually and then vibrate it to thoroughly mix and shake loose imbedded bubbles

      @@JohnVallevikGreen That applies to epoxy pours where you don't want visible holes or cavities in the molded part. For epoxy used as an adhesive, you need to mix it fast.

    Your work is great. I have never seen so much thoroughness in an electronics build like this. I was curious about building a DIY ultrasonic cleaner from purchased drivers and transducers but I have neither the welding resources nor the component troubleshooting ability that you do. Thank you very much for sharing this experience with us and providing this high level of useful advice. I will keep educating myself about purchasing--and maybe even slightly modifying--an ultrasonic cleaner for my own work and projects but I will not take myself down the rabbit hole of trying to build my own. Thank you!

    I used to work in an electronic parts cleaning company here in California USA and I have used and operated a huge cleaning machine with two ultrasonic tanks, about 40 gallons each, more or less. One is for the detergent mixture, which is automatically mixed by the computerized machine and the other has plain DI water only for rinsing. We used D.I. water (distilled industrial water), which is a very pure type of water for both tanks. I have retired 6 years ago from that work and glad to watch your video about ultrasonic cleaners and how to build one.
