一、功率的选择:
1、 Power selection:
超声波清洗机有时用小功率,花费很长时间也没有污垢。而如果功率达到一定数值,很快便将污垢去除。若选择功率太大,空化强度将大大增加,清洗效果是提高了,这时较精密的零件也产生了蚀点,而且清洗机底部振动板空化严重,水点腐蚀也增大,在采用三氯乙烯等有机溶剂时,基本上没有问题,采用水或水溶性清洗液时,易于受到水点腐蚀,如果振动板表面已受到伤痕,强功率下水底产生空化腐蚀更严重,因此要按实际使用情况选择超声功率。
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、频率的选择:
2、 Frequency selection:
超声波清洗机频率从28 kHz 到 120kHz 之间,在使用水或水清洗剂时由空穴作用引起的物理清洗力显然对低频有利,一般使用 28-40kHz 左右。对小间隙、狭缝、深孔的零件清洗,用高频(一般 40kHz 以上)较好,甚几百 kHz 。对钟表零件清洗时,用 100kHz 。若用宽带调频清洗,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、清洗篮的使用 :
3、 Use of cleaning basket:
在清洗小零件物品时,常使用网篮,当频率为 28khz 时使用 10mm 以上的网眼为好。
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、清洗液温度:
4、 Cleaning fluid temperature:
水清洗液适宜的清洗温度为 40-6 ,尤其在天冷时若清洗液温度低空化效应差,清洗效果也差。因此有部分清洗机在清洗缸外边绕上加热电热丝进行温度控制,当温度升高后空化易发生,所以清洗效果较好。当温度继续升高以后,空泡内气体压力增加,引起冲击声压下降,效果也会减弱。 有机溶剂清洗液则要接近于沸点的温度来清洗。
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确定:
5、 Determination of the amount of cleaning fluid and the position of cleaning parts:
一般清洗液液面高于振动子表面 100mm 以上为佳。由于单频清洗机受驻波场的影响,波节处振幅很小,波幅处振幅大造成清洗不均匀。因此选择清洗物品位置应放在波幅处。
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.
