在选择合适超声波清洗机清洗技术参数的前提下,其清洗工序和工艺流程也十分重要。清洗过程实质上是零件表面、污染物、清洗介质三者之间复杂的物理、化学和机械作用过程。常用的超声波清洗形式是将零件浸入盛有清洗液的超声波清洗槽内,超声波发生机把50HZ常用电转换成超声频的电能,传输给换能器,再由超声波换能器将高频电能转换成超声振动,辐射至清洗液内进行清洗。
的超声波清洗工艺,一般常采用多槽式全自动、联合清洗程序。清洗时将零件装入用透声材料做成的网篮中,进行自动、定时、循环清洗。对于有大量污垢的零件可采用浸、喷、冲等方法进行预清洗,然后再进行超声波清洗。
超声波清洗工艺多选用水基清洗剂,由于这类洗剂比ODS洗剂对油脂及亲油污物的溶解性、渗透性和分散性能力差。所以必须采用多槽式超声波加温脱脂、超声波加温清洗,以加快污物的溶解和分散,使污物脱离零件(粗洗)。超声波漂洗(精洗)是用纯水洗去零件表面所残留的清洗介质。高压冲淋是采用全方位从上至下的方式进行高压纯水喷射,以冲洗小盲孔及缝隙中的污染介质。对冲淋后的洁净零件进行快速热风烘干或蒸汽烘干,以防零件表面氧化腐蚀。

In the selection of suitable ultrasonic cleaning machine technical parameters in the premise, the cleaning process and procedure is also very important. The cleaning process is essentially the parts surface, pollutants, the cleaning medium between the three complex physical, chemical and mechanical processes. The most commonly used ultrasonic cleaning form submerse part filled with cleaning liquid ultrasonic cleaning tank, ultrasonic generator50HZ electric conversion into super audio power, is transmitted to the transducer, the ultrasonic transducer will high frequency electrical energy into ultrasonic vibration, radiation to the cleaning fluid for cleaning.
Advanced ultrasonic cleaning technology, general usually adopts multiple groove type full automatic, United cleaning procedure. When cleaning the part into using acoustic material basket, automatic, timing, circulation cleaning. For a large number of dirt parts application is made by dipping, spraying, washing methods such as cleaning, then ultrasonic cleaning.
Ultrasonic cleaning technology using a water-based cleaning agent, because this kind of lotion than ODS lotion on grease and oil dirt solubility, permeability and dispersion ability difference. So it is necessary to use the multi-slot ultrasonic heating degreasing, ultrasonic heating cleaning, to speed up the dirt dissolved and dispersed, so dirt out of parts(rough wash). Ultrasonic washing(wash)is a water wash the parts surface residual cleaning medium. High pressure shower is used in all directions from top to bottom of the way of pressure water injection, to rinse small blind hole and the gap of the contaminated medium. Hedge leaching after clean parts for rapid drying or drying steam, to prevent surface oxidation corrosion.
