超聲波清洗機(jī)主要由超聲波發(fā)生器、清洗槽和箱體三部分組成
Ultrasonic cleaning machine is mainly composed of ultrasonic generator, cleaning tank and box
1. 箱:
1. Case:

The panel of ultrasonic cleaning machine is equipped with ammeter, power switch, output socket, frequency and phase power series adjustment knob, and the back is equipped with power inlet socket and safety tube.
2. 超聲波發(fā)生器:
2. Ultrasonic generator:
它由電力變壓器和整流系統(tǒng)、振蕩器、驅(qū)動級、功率放大器和輸出變壓器組成。
It consists of power transformer and rectifier system, oscillator, drive stage, power amplifier and output transformer.
3.清洗罐:
3. Cleaning tank:
它由不銹鋼水箱、復(fù)合換能器和配套電感組成。換能器在不銹鋼箱體底部干燥,不銹鋼箱體與箱體框架之間有阻尼裝置。
It consists of stainless steel water tank, composite transducer and matching inductor. The transducer is dry at the bottom of the stainless steel box, and there is a damping device between the stainless steel box and the box frame.
2、超聲波清洗機(jī)主要參數(shù)
2. Main parameters of ultrasonic cleaning machine
1. 頻率:
1. Frequency:
頻率≥20kHz,可分為低頻、中頻、高頻三部分。
Frequency ≥ 20kHz, can be divided into low frequency, medium frequency, high frequency three parts.
2. 清洗介質(zhì):
2. Cleaning medium:
超聲波清洗一般采用兩種清洗劑:化學(xué)溶劑清洗劑、水性清洗劑等。清洗介質(zhì)的化學(xué)作用可以加速超聲波清洗的效果。超聲波清洗是一種物理功能。這兩個功能結(jié)合在一起,以充分和較好地清潔對象。
Ultrasonic cleaning generally uses two kinds of cleaning agents: chemical solvent cleaning agent, water-based cleaning agent, etc. The chemical action of cleaning medium can accelerate the effect of ultrasonic cleaning. Ultrasonic cleaning is a physical function. These two functions are combined to fully and better clean the object.
3.功率密度:
3. Power density:
功率密度=發(fā)射功率(W) /發(fā)射面積(cm2)通?!?.3w/cm2。超聲功率密度越大,空化效應(yīng)越強,速度越快,清洗效果越好。但對于精度高、表面光潔度好的物體,長時間的高功率密度清洗會造成物體表面的空化腐蝕。
Power density = transmitting power (W) / transmitting area (cm2), usually ≥ 0.3w/cm2. The higher the ultrasonic power density is, the stronger the cavitation effect is, the faster the speed is, and the better the cleaning effect is. But for the object with high precision and good surface finish, long time high power density cleaning will cause cavitation corrosion on the surface of the object.
4. 超聲波頻率:
4. Ultrasonic frequency:
超聲頻率越低,在液體中越容易產(chǎn)生空化,強度越大,作用越強。適用于工件的初洗(粗、臟)。高頻,超聲波方向強,適用于精細(xì)物體清洗。
The lower the ultrasonic frequency is, the easier cavitation is to occur in the liquid, and the stronger the intensity is, the stronger the effect is. It is suitable for the initial washing of workpieces (rough and dirty). High frequency, strong ultrasonic direction, suitable for fine object cleaning.
5. 清洗溫度:
5. Cleaning temperature:
一般來說,超聲空化效果在30℃~ 40℃時較好。溫度越高,影響越顯著。超聲波的實際應(yīng)用一般采用50℃- 70℃的工作溫度。
Generally speaking, the ultrasonic cavitation effect is better at 30 ℃ ~ 40 ℃. The higher the temperature, the more significant the effect. The practical application of ultrasonic generally adopts the working temperature of 50 ℃ - 70 ℃.
