超声波清洗机是近年来发展起来的超声波清洗技术，已经在汽车配件、电镀工具、除油污等表面处理生产中得到了较为广泛的应用。那么您知道常用超声波清洗机频率是多少吗？

Ultrasonic cleaning machine is a kind of ultrasonic cleaning technology developed in recent years, which has been widely used in the production of surface treatment of automobile accessories, electroplating tools, oil removal, etc. Do you know the frequency of commonly used ultrasonic cleaners?

超声波频率越低，在液体中产生的空化越容易，产生的力度大，作用也越强，适用于工件粗、脏、初洗，频率高则超声波方向性强，适合于精细的物件清洗，所以常用超声波清洗机频率是28khz、40khz。

The lower the ultrasonic frequency is, the easier the cavitation is generated in the liquid, the greater the force is, and the stronger the effect is. It is suitable for rough, dirty, and initial cleaning of workpieces. The higher the frequency is, the stronger the ultrasonic directivity is, and it is suitable for cleaning fine objects. Therefore, the frequency of commonly used ultrasonic cleaners is 28 khz, 40 khz.

实验表明，经过超声波清洗机高频清洗后干燥的零件表面润湿接触角小，污垢残留少。超声波清洗机低频清洗时，镀层耐腐蚀性差，超声波清洗过后，零件电镀表面均匀平整，耐蚀性有明显提高，采用超声波清洗，工艺简单，操作简便，劳动强度低，清洗质量好，清洗效率高，而且易于实现零、部件清洗自动化。大大的提高工作效率。特别对深孔、盲孔、凹凸槽的清洗是理想的设备。

The experiment shows that the wetted contact angle of the dried part surface after high-frequency cleaning by ultrasonic cleaner is small, and the dirt residue is small. When the ultrasonic cleaning machine is used for low-frequency cleaning, the corrosion resistance of the coating is poor. After the ultrasonic cleaning, the electroplating surface of the parts is even and flat, and the corrosion resistance is significantly improved. The ultrasonic cleaning is simple in technology, simple in operation, low in labor intensity, good in cleaning quality, and high in cleaning efficiency, and easy to realize the automation of parts and components cleaning. Greatly improve work efficiency. Especially for deep hole, blind hole, concave convex groove cleaning is an ideal equipment.

超声波清洗的优点相比其他多种的清洗方式，超声波清洗机显示出了巨大的优越性，它的高的效率和高清洁度，得益于其声波在介质中传播时产生的穿透性和空化冲击疚，所以很容易将带有复杂外形，内腔和细空的零部件清洗干净，对一般的除油、防锈、磷化等工艺过程，在超声波作用下只需两三分钟即可完成，其速度比传统方法可提高几倍，甚至几十倍。

Advantages of ultrasonic cleaning Compared with other cleaning methods, the ultrasonic cleaning machine shows great advantages. Its high efficiency and high cleanliness benefit from the penetrability and cavitation impact caused by its sound wave when it travels in the medium, so it is easy to clean the parts with complex shape, inner cavity and fine air. It can also clean the general process of oil removal, rust prevention, phosphating, etc, Under the action of ultrasonic wave, it can be completed in only two or three minutes, and its speed can be several times, or even dozens of times, higher than that of traditional methods.

这在许多对产品表面质量和生产率要求较高的场合，更突出地显示了用其它处理方法难以达到或不可取代的结果。您要了解更多相关事项的话就来我们网站www.jnthcsb.com咨询看看吧！
