1、 Power selection:

超聲波清洗機(jī)有時(shí)用小功率，花費(fèi)很長時(shí)間也沒有清除污垢。而如果功率達(dá)到一定數(shù)值，很快便將污垢去除。若選擇功率太大，空化強(qiáng)度將大大增加，清洗效果是提高了，這時(shí)較精密的零件也產(chǎn)生了蝕點(diǎn)，而且清洗機(jī)底部振動(dòng)板空化嚴(yán)重，水點(diǎn)腐蝕也增大，在采用三氯乙烯等有機(jī)溶劑時(shí)，基本上沒有問題，采用水或水溶性清洗液時(shí)，易于受到水點(diǎn)腐蝕，如果振動(dòng)板表面已受到傷痕，強(qiáng)功率下水底產(chǎn)生空化腐蝕更嚴(yán)重，因此要按實(shí)際使用情況選擇超聲功率。

The ultrasonic cleaning machine sometimes uses low power and takes a long time without removing dirt. If the power reaches a certain value, the dirt will be removed soon. If the power is too large, the cavitation intensity will be greatly increased and the cleaning effect will be improved. At this time, the more precise parts also have corrosion spots. In addition, the vibration plate at the bottom of the cleaning machine has serious cavitation and water spot corrosion. There is basically no problem when using organic solvents such as trichloroethylene. When using water or water-soluble cleaning solution, it is easy to be corroded by water spots. If the surface of the vibration plate has been damaged, Cavitation and corrosion are more serious at the bottom of the water under high power, so the ultrasonic power should be selected according to the actual use.

二、頻率的選擇：

2、 Frequency selection:

超聲波清洗機(jī)頻率從28 kHz 到 120kHz 之間，在使用水或水清洗劑時(shí)由空穴作用引起的物理清洗力顯然對低頻有利，一般使用 28-40kHz 左右。對小間隙、狹縫、深孔的零件清洗，用高頻(一般 40kHz 以上)較好，甚至幾百 kHz 。對鐘表零件清洗時(shí)，用 100kHz 。若用寬帶調(diào)頻清洗，效果更良好。

The frequency of ultrasonic cleaning machine ranges from 28 kHz to 120 kHz. When using water or water cleaning agent, the physical cleaning force caused by the action of holes is obviously beneficial to the low frequency. Generally, it is about 28-40 kHz. For parts with small gaps, slits and deep holes, high frequency (generally above 40KHz) is better, even hundreds of kHz. When cleaning clock parts, use 100kHz. If you use broadband FM cleaning, the effect is better.

三、清洗籃的使用 ：

3、 Use of cleaning basket:

在清洗小零件物品時(shí)，常使用網(wǎng)籃，當(dāng)頻率為 28khz 時(shí)使用 10mm 以上的網(wǎng)眼為好。

When cleaning small parts, the basket is often used. When the frequency is 28kHz, it is better to use a mesh of more than 10mm.

四、清洗液溫度：

4、 Cleaning fluid temperature:

水清洗液適宜的清洗溫度為 40-6 ，尤其在天冷時(shí)若清洗液溫度低空化效應(yīng)差，清洗效果也差。因此有部分清洗機(jī)在清洗缸外邊繞上加熱電熱絲進(jìn)行溫度控制，當(dāng)溫度升高后空化易發(fā)生，所以清洗效果較好。當(dāng)溫度繼續(xù)升高以后，空泡內(nèi)氣體壓力增加，引起沖擊聲壓下降，效果也會減弱。 有機(jī)溶劑清洗液則要接近于沸點(diǎn)的溫度來清洗。

The optimum cleaning temperature of water cleaning solution is 40-6, especially in cold weather. If the temperature of cleaning solution is low and the cavitation effect is poor, the cleaning effect is also poor. Therefore, some cleaning machines wrap heating wires around the outside of the cleaning cylinder for temperature control. When the temperature rises, cavitation is easy to occur, so the cleaning effect is good. When the temperature continues to rise, the gas pressure in the cavity increases, causing the impact sound pressure to decrease, and the effect will also be weakened. Organic solvent cleaning solution should be cleaned at a temperature close to the boiling point.

五、清洗液量的多少和清洗零件的位置的確定：

5、 Determination of the amount of cleaning fluid and the position of cleaning parts:

一般清洗液液面高于振動(dòng)子表面 100mm 以上為佳。由于單頻清洗機(jī)受駐波場的影響，波節(jié)處振幅很小，波幅處振幅大造成清洗不均勻。因此佳選擇清洗物品位置應(yīng)放在波幅處。 (較有效范圍3-18公分)

Generally, the liquid level of cleaning fluid is more than 100mm higher than the surface of vibrator. Because the single frequency cleaning machine is affected by the standing wave field, the amplitude at the wave node is very small, and the amplitude at the wave amplitude is large, resulting in uneven cleaning. Therefore, the best choice for cleaning items should be placed at the wave amplitude. (more effective range: 3-18cm)
