液压控制在工程设计中被广泛应用，特别是大型设备，飞机、挖掘机等液压系统作为控制系统主要功能部分，结构复杂，零部件精度高，已达微米、亚微米级，高精度决定了液压系统抗污染需求高，而污染很大程度上影响着系统工作，据资料记载，液压系统故障的75%以上源于污染液压系统的污染主要来源于零部件自身。
Hydraulic control is widely used in engineering design, especially for large equipment, aircraft, excavators and other hydraulic systems as the main functional parts of the control system, with complex structure and high precision of parts, which has reached the micron and submicron levels. The high precision determines the high demand for anti-pollution of the hydraulic system, and the pollution greatly affects the system work, according to the data records, More than 75% of the hydraulic system faults are caused by the pollution of the hydraulic system. The pollution of the hydraulic system mainly comes from the parts themselves.
即产品在生产制造过程中产生的，因未能彻底去除而带到系统污染物主要包括研磨膏、铁屑、防锈油、乳化液、电蚀物、盐类、其他等这些污染物或残留在零件表面，或聚集零件深孔或盲孔中，在工作液作用下，污染物会到处移动，破坏工作面，造成油路堵塞，影响系统工作，降低液压系统使用寿命，甚至造成事故随着液压控制技术发展和液压控制系统应用，简单的清洗方法，已经无法保证液压零件清洁度要求，这时候工业超声波清洗机的应用，提高工业清洗质量和效率，解决了液压件清洗难题。
That is, the pollutants generated in the production and manufacturing process of the product and brought into the system due to the failure to completely remove them mainly include grinding paste, iron filings, antirust oil, emulsion, electrical corrosion, salt, and other pollutants, which may remain on the surface of the part or gather in the deep or blind holes of the part. Under the action of the working fluid, the pollutants will move everywhere, damage the working surface, cause oil blockage, affect the system work, and reduce the service life of the hydraulic system, Even with the development of hydraulic control technology and the application of hydraulic control system, simple cleaning methods can no longer ensure the cleanliness requirements of hydraulic parts. At this time, the application of industrial ultrasonic cleaning machine can improve the quality and efficiency of industrial cleaning and solve the problem of hydraulic parts cleaning.

超声波清洗作为一种效果显着的强化清洗方法其机理，是利用了超声波在液体中的空化作用在超声波作用下，液体分子时而受拉，时而受压，形成了一个个微小空腔，激发成直径在50~500um，并被清洗液蒸汽充满的细小气泡，即“空化泡”由于空化泡内维压力相差十分悬殊，待空化泡破裂时，会产生局部压力冲击波，气压力可达几百个大气压在这种压力作用下，附着在零件表面的各种污垢会被剥落与此同时，在超声波作用下，清洗液脉冲和搅拌加剧，溶解加速，从而强化清洗效果。
The mechanism of ultrasonic cleaning, as an effective enhanced cleaning method, is to take advantage of the cavitation effect of ultrasonic in the liquid. Under the action of ultrasonic, the liquid molecules are sometimes pulled and sometimes pressed to form tiny cavities, which are excited into tiny bubbles with a diameter of 50~500um and filled with the cleaning liquid vapor, that is, "cavitation bubbles" due to the great difference in the internal pressure of cavitation bubbles, when the cavitation bubbles break, Local pressure shock wave will be generated, and the pressure force can reach hundreds of atmospheres. Under this pressure, various dirt attached to the surface of the parts will be peeled off. At the same time, under the action of ultrasonic wave, the pulse and stirring of the cleaning solution will be intensified, and the dissolution will be accelerated, thus strengthening the cleaning effect.
超声波清洗设备多为箱槽结构，清洗槽大小决定单次清洗能力，可以根据被清洗零部件大小和数量选择清洗槽清洗形式可以是单槽清洗，也可以是多槽清洗，单槽清洗即为零部件在一个清洗槽内清洗完毕多槽清洗，是指将清洗过程分为多个工步，零部件从第一个槽清洗后，进人第二个槽继续清洗，之后再进人第三个槽，第四个槽一般每个槽主要去除一种污染物清洗液需要根据零部件材料选择，金属材料常用的清洗液有汽油、酒精、水剂等，非金属材料清洗液多为对零部件无损害的溶液单槽清洗时常选用汽油、酒精等挥发性溶液，溶液挥发性强化清洗效果;多槽清洗时，多选用水剂，主要考虑降低成本和提高安全性等因素不论是单槽清洗还是多槽清洗，随着清洗过程的进行，溶液温度会逐渐上升，同时也会导致被清洗零部件温度上升，一般多槽清洗后温度在45一55℃，单槽清洗后温度在25~40℃两种清洗方式都会伴随出现“发泡”现象，发泡会增强去污力清洗前需要对零部件进行防护处理，保护被清洗零部件，清洗后对零件进行防锈处理，肉片下来，然后卷在春卷皮了，放上黄瓜丝，蘸上酱料，味道非常棒。
The ultrasonic cleaning equipment is mostly of tank structure. The size of the cleaning tank determines the single cleaning capacity. The cleaning tank can be selected according to the size and quantity of the parts to be cleaned, which can be single tank cleaning or multiple tank cleaning. Single tank cleaning means that the parts are cleaned in a cleaning tank, and the cleaning process is divided into multiple steps. After the parts are cleaned from the first tank, they enter the second tank to continue cleaning, Then enter the third tank. Generally, each tank in the fourth tank mainly removes one kind of pollutant. The cleaning solution needs to be selected according to the material of the parts. The commonly used cleaning solutions for metal materials include gasoline, alcohol, water, etc. The non-metallic material cleaning solution is mostly the solution that does not damage the parts. Volatile solutions such as gasoline, alcohol, etc. are often used for single tank cleaning, and the volatility of the solution enhances the cleaning effect; In the case of multi-tank cleaning, the water agent is mostly selected, and the main consideration is to reduce the cost and improve the safety. Whether it is single-tank cleaning or multi-tank cleaning, the temperature of the solution will gradually rise as the cleaning process proceeds, and the temperature of the cleaned parts will also rise. Generally, the temperature after multi-tank cleaning is 45-55 ℃, and the temperature after single-tank cleaning is 25-40 ℃, Foaming will enhance the detergency. Before cleaning, the parts need to be protected. After cleaning, the parts need to be rust proofed. The meat is sliced and then rolled on the skin of the Spring rolls. The cucumber is put on the shredded cucumber and dipped in the sauce. The taste is very good.
