【正文】 aned must be considered when developing an ultrasonic cleaning process. A large dense mass, for example, prevents internal surfaces from being thoroughly cleaned (., metal castings). A rule of thumb is that the load by weight should be less than the weight of half the water volume. So, for example, in five gallons (approximately 40 lbs .) of water, the maximum workload should be less than 20 lbs . In some cases, it is better to ultrasonically clean two smaller loads rather than one larger load. Each of the factors outlined here must be considered when specifying an ultrasonic application to ensure a high level of cleaning success. Neglecting any single factor can have a negative impact on the overall cleaning process. 。 河北農(nóng)業(yè)大學(xué)畢業(yè)設(shè)計(jì)外文原文 Ultrasonic Cleaning Ultrasonic cleaning is a good fit for a wide range of applications, from removing swarf and grinding and polishing residue to treating parts covered in oil, grease, or layers of paint. Ultrasonics can be used to clean miniature watch parts or to support the overhaul of jumbo jet engines. And from an industry perspective, the fields of electrotechnics, precision mechanics and light engineering, optics, metal processing, and medical equipment have proven particularly receptive to the ultrasonic concept. So the impact of ultrasonic cleaning is clearly recognizable. But to truly understand the value of ultrasonics, one must understand how ultrasonic cleaners really work. Ultrasonic Cleaning Explained The cleansing effect of ultrasound is the product of a phenomenon called cavitation. Billions of minute gas bubbles implode, causing shock waves that undermine dirt and blast it off a part’s surface. One of the key advantag
