机械零部件的清洁度是评价产品质量的指标之一。采用超声波清洗并配用水剂清洗液,清洗油脂,污垢和研磨膏微粒等可以比现有的清洗工艺效果好。一、超声波清洗的机理和配用清洗液超声波的清洗机理是基于超声的空化效应。清洗槽底部的超声换能器在高频电能作用下,被激发作弹性的机械振动,从而向槽内清洗液辐射超声波。在一定声强和频率下,清洗液中产生大量气泡,这些气泡随超声振动反复地生成和闭合,这种现象即称为空化效应。当空化气泡完全闭合时,会产生自中心向外的微激波,其压强可达几千个大气压,这种冲击力能将
Mechanical parts cleanliness is one of the indicators to evaluate product quality. The use of ultrasonic cleaning and dispensing liquid cleaning fluid, cleaning grease, dirt and abrasive particles such as particles than the existing cleaning process is effective. First, the mechanism of ultrasonic cleaning and cleaning solution with ultrasonic cleaning mechanism is based on the cavitation effect of ultrasound. Ultrasonic transducer at the bottom of the cleaning tank is excited to make elastic mechanical vibration under the action of high frequency electric energy so as to radiate ultrasonic wave to the cleaning liquid in the tank. Under a certain sound intensity and frequency, a lot of bubbles are generated in the cleaning solution. These bubbles are repeatedly generated and closed with ultrasonic vibration. This phenomenon is called cavitation effect. When the cavitation bubbles are completely closed, they will generate micro-shocks from the center outward, the pressure up to thousands of atmospheres, this impact will be able to
