• Adjusting an atomizer circuit

    From Commander Kinsey@21:1/5 to All on Mon Apr 11 09:33:22 2022
    XPost: alt.home.repair, uk.d-i-y

    I've bought an atomizer circuit and "speaker", which appears to want a water depth of 1cm. However the tank/valve I have produces 2cm depth. Is there a way to change the electronics to make it vibrate water into vapour at a greater depth?

    As Tim 'the toolman' Taylor would say, more power!

    At one time I had a job where we built Ultrasonic energy amplifiers
    and transducers.
    We sat our transducer in 6" of water and could blow a plume 6" to 10"
    above the surface of the water.
    But it was 1000 watts and a 2" transducer.

    This is 25W, a 1 inch transducer. The same as the thing I replaced. But it refuses to atomize through that depth of water. The old one did (although it did burn out after 9 months). How do you suggest I increase the power? And should I be looking at
    a higher power or a higher frequency?

    I have no idea how that would work. There's nothing special about it that I can see, just a 1 inch metal transducer. Similar circuit powering it as the original humidifier. It's this: https://www.ebay.co.uk/itm/174783229310

    15kV with all the conforming specs for medical devices with human
    contact. microamp curren shutdown and nearly instant. Took a couple
    years to develop and you could fit 6 of them in a cigarette pack
    (100mm). It even had a vacuum potted box on the mutiplier end.
    It ran from about 4.5 volts up past 9 volts. and had a four segment HV transformer before the multiplier that had about 1000 turns of #54 on
    each segment. Short of not being able to do much work like say fire an
    X-ray tube, it was one of the most precise, most complicated supplies I developed.

    Are not piezo wafers all quite flat?

    It could be frequency tuned to respond best at a specific depth.

    Transducers are fairly high Q devices and capacitive, you generally need
    a series inductor to tune them. Although I think some circuits actually
    use the
    L and transducer C for tuning and use a power oscillator. So they will oscillate at the
    correct frequency for a replaced transducer, within reason.

     Somewhere, I have an interesting curve showing the power required to
    cause cavitation in water.

    I found the graph.
    https://www.dropbox.com/s/07dgqxafqbm4f8x/Cavitation%20paint.jpg?dl=0
    Note: Cavitation threshold is dependent on whether the water is degassed
    or not.

    At low Ultrasonic frequencies it takes little power to get cavitation
    (on or near the faceplate), but as you move up
    to several hundred Kilohertz it takes much more power. When I first
    started with the company, they used
    transducers around 400kHz, but shortly changed to 620kHz. As I mention
    we pulsed a 2" PZT 8 ceramic disk,
    epoxied to a 1/16" aluminum faceplate with 1000 watts and didn't have cavitation on the faceplate.
    We did have a reflector that would focus the beam to a point and we
    would get a fuzzy cottony looking
    area that made a hissing sound. We could also melt plastic in an ice
    water bath.
     Transducer held up under power, heat was the problem, so our
    transducer was run in an ice bath with an FEP Teflon window
    separating the Fluid under test from the Ice Bath. One of our customers
    found PTFE Teflon windows caused failed experiments.
     He was killing e.coli in milk and was getting high kill rates, then
    had a tear in his Teflon window, he got some new Teflon windows (PTFE)
    and could not get his high kill rates again. Lots of phone calls before
    that was solved, because we didn't know either.

    Naming a disease is easy. It's the first step in identifying the disease - or more frequently a group of diseases with similar symptoms. Curing any particular disease can be a lot harder, and some of them are always going to turn out to be incurable.

    Quite what Commander Kinsey thought that he was saying here isn't obvious. What is obvious is that he should have shut up.

    I also made a Piezo stack stimulator amplifier which was 2kW and was
    20Hz to 20kHz range. The output included a HUGE coil in a huge
    ferrite core pair. Those were fun to wind. It had an 18 inch long
    heat sink for the row of drivers it had on it. Have to mount them
    all, and THEN solder the heavy legs to keep it all coplanar to the
    sink. It also had two 2kVA transformers sitting in the bottom of the
    cabinet.

    It drove a stack of Piezo chips about 30mm in diameter and a
    hundred tall (4 inches) for a total deflection of just over one
    millimeter, which we doubled with a 2:1 rocker arm which drove a
    presicion lathe cutting tool. That coupled with a feedback loop on
    the lathe allowed for optical quality surfaces and it was used to cut
    perfect 'molds' for 1 inch diameter contact lenses for race horses.

    That was a fun development.

    Sounds like it could be used to prevent cavitation on propellers
    for subs. Shame though that it is acoustic. Like raising a flag (or
    firing up a boom box) saying "Here I am!"
