一、功率的選擇:
1、 Power selection:
超聲波清洗機有時用小功率,花費很長時間也沒有污垢。而如果功率達到一定數(shù)值,很快便將污垢去除。若選擇功率太大,空化強度將大大增加,清洗效果是提高了,這時較精密的零件也產(chǎn)生了蝕點,而且清洗機底部振動板空化嚴重,水點腐蝕也增大,在采用三氯乙烯等有機溶劑時,基本上沒有問題,采用水或水溶性清洗液時,易于受到水點腐蝕,如果振動板表面已受到傷痕,強功率下水底產(chǎn)生空化腐蝕更嚴重,因此要按實際使用情況選擇超聲功率。
The ultrasonic cleaning machine sometimes uses low power and takes a long time to remove the dirt. If the power reaches a certain value, the dirt will be removed quickly. If the power is too high, the cavitation strength will be greatly increased, and the cleaning effect will be improved. At this time, the more precise parts also produce corrosion spots. Moreover, the vibration plate at the bottom of the cleaning machine has serious cavitation, and the water-point corrosion is also increased. When using organic solvents such as trichloroethylene, there is basically no problem. When using water or water-soluble cleaning fluid, it is easy to suffer from water spot corrosion The cavitation corrosion is more serious in the water bottom under high power, so the ultrasonic power should be selected according to the actual situation.
二、頻率的選擇:
2、 Frequency selection:
超聲波清洗機頻率從28 kHz 到 120kHz 之間,在使用水或水清洗劑時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,甚幾百 kHz 。對鐘表零件清洗時,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 cavitation is obviously beneficial to the low frequency. Generally, the frequency is about 28-40 kHz. For parts with small clearance, slit and deep hole, it is better to use high frequency (generally more than 40KHz) or even several hundred kHz. When cleaning the clock parts, use 100kHz. If using 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,常使用網(wǎng)籃,當頻率為 28khz 時使用 10mm 以上的網(wǎng)眼為好。
When cleaning small parts and articles, the basket is often used. When the frequency is 28kHz, it is better to use more than 10mm mesh.
四、清洗液溫度:
4、 Cleaning fluid temperature:
水清洗液適宜的清洗溫度為 40-6 ,尤其在天冷時若清洗液溫度低空化效應差,清洗效果也差。因此有部分清洗機在清洗缸外邊繞上加熱電熱絲進行溫度控制,當溫度升高后空化易發(fā)生,所以清洗效果較好。當溫度繼續(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。 有機溶劑清洗液則要接近于沸點的溫度來清洗。
The suitable cleaning temperature of water cleaning solution is 40-6, especially in cold weather, if the temperature of cleaning fluid is low, the cavitation effect is poor. Therefore, there are some cleaning machines in the cleaning cylinder on the outside of the heating wire 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, which causes the impact sound pressure to decrease, and the effect will also be weakened. Organic solvent cleaning solution should be close to the boiling point temperature to clean.
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子表面 100mm 以上為佳。由于單頻清洗機受駐波場的影響,波節(jié)處振幅很小,波幅處振幅大造成清洗不均勻。因此選擇清洗物品位置應放在波幅處。
Generally, it is better that the liquid level of cleaning liquid is more than 100 mm higher than the surface of vibrator. Due to the influence of standing wave field, the amplitude of single frequency cleaning machine is very small, and the amplitude of wave amplitude is large, resulting in uneven cleaning. Therefore, the location of cleaning articles should be placed at the wave amplitude.
