How to Measure Ultrasonic Cleaner Power Efficiency

by:Sinobakr     2020-04-25
We now have ultrasonic cleaners distributed all over the world in a truly wide range of applications. They range from the very small, used for gems, to the mid-sized used at home or in labs, to the rather large ones in industry. The units effectively provide us with the 'next-generation' of cleaners. They are capable of substituting virtually any conventional liquid-based cleaning process with their advanced functionality. They combine compactness, utility, ease of use, efficiency, and low power consumption with a high quality of cleaning. The ultrasonic device cleans by converting or consuming electrical power into ultrasonic power, which in turn transforms into cleaning power. It is all about the use and conversion of energy, or power into another one - sonic. Whether the process scale is small, medium or large, electric power is a continuous or recurring expense. To extract the most from the ultrasonic cleaning machine, it must not only work well, it must do it at a lower cost per weight or volume of object cleaned. Of course, one can factor in the time and labour saved as a positive 'input'. We assume the cost and scale of the particular ultrasonic cleaner in question is large enough to justify the purchase of a good wattmeter or powermeter. A very simple intuitive calculation provides us with a sufficiently good estimate of the as-is power efficiency, expressed in percentage. See that the tank is as-installed, heat-insulated or not. Place a typical, average object to be cleaned in the mesh basket. After autodegassing, run the cleaner, as usual, for the regular duration of time - but take note of power-meter readings every 5-10 minutes, or so. Then the simple formula below provides a measure of the power efficiency: P.eff. = E[in-elec]/E[out-heat]; where E[in-elec] is the net electrical energy consumed, and E[out-heat] is the measured, converted adiabatic (no heat loss) energy from this in the liquid. E[in-elec] = P[in-elec] * Δt; where P[in-elec] is the average power, Δt = total time of experiment E[out-heat] = m*Cp*ΔT; where m = mass of liquid (kg), Cp = avg. liquid specific heat capacity (kg/J-C); ΔT = rise in temperature during the experimental ultrasonic heating run. Suppose DI water is the cleaning liquid, in a medium-sized bath of 10 liters capacity, which is well insulated, so we can neglect all heat losses. Power Efficiency(%) = E[out-heat]/E[in-elec] * 100 E.g. m = 10 kg (m = (density) 1 kg/L * (volume) 10 L); Cp = 4200 (J/kg-C), ΔT = 80 - 30 = 50 deg C, in a run of Δt = 2 hours, which is typical of DI water operations. Then E[out-heat] = m*Cp*ΔT = 10*4200*50 = 2.1 MJ (MJ = 1 million J). From the Power-meter, suppose we get an average value of P[in-elec] = 350 W (Watts). The electrical power consumed is E[in-elec] = P[in-elec] * Δt = 2.52 MJ. The power efficiency then is the ratio. Power Efficiency(%) = E[out-heat]/E[in-elec] * 100 = 2.1/2.52 *100 = 83.3%, typical of a small-mid cleaner in good condition. The only additional instrumentation needed is the power-meter. This procedure should be repeated for every fresh liquid and material concentration. It should be repeated every week or fortnight. A marked drop in efficiency is a key indicator that something is going wrong. It would signify a need to get the equipment checked by a professional technician or engineer, from the vendor or the manufacturer.
