In the batch cleaning of blind hole parts, due to its structural characteristics, a large number of parts are placed in the cleaning cage and immersed in the cleaning solution at the same time. Because of the surface tension of the cleaning fluid, the air in the grooves, slits and blind holes can not be removed in time, but is blocked in the blind hole, so that the cleaning agent can not fully contact the surface of parts, it is difficult to effectively and thoroughly remove the residual cutting fluid, pressure oil and coolant in the blind hole. So at this time, how to clean the blind hole ultrasonic cleaning equipment?

　　種方法：

　　在設計五金件超聲波清洗機時，可以在罐體上加一個壓縮空氣噴嘴。外部工廠氣源，在清洗盲孔零件時，將工件慢慢放入，盡可能讓水流入孔內。零件放置后，利用壓縮空氣使水產生大量水柱沖擊工件。為了使堵塞在孔口中的氣泡爆裂，達到更好的對盲孔部位的超聲波清洗效果。

　　The first method:

　　In designing ultrasonic cleaning machine for hardware, a compressed air nozzle can be added to the tank body. External factory air source, when cleaning the blind hole parts, slowly put the workpiece into the hole, as much as possible to let the water flow into the hole. After the parts are placed, compressed air is used to generate a large number of water columns to impact the workpiece. In order to make the bubbles blocked in the orifice burst, to achieve a better ultrasonic cleaning effect on the blind hole.

　　第二種方法：

　　The second method:

　　使用中高頻結合的超聲波清洗設備。利用高頻超聲波，原理是高頻振蕩，使堵塞在盲孔中的氣體超聲波清洗機的氣泡破裂，鐵屑被一掃而空。

　　The use of high frequency combined with ultrasonic cleaning machine. The use of high frequency ultrasonic, the principle is high frequency oscillation, so that blocked in the blind hole in the gas ultrasonic cleaning machine bubble burst, iron filings were swept away.

　　一般情況下，超聲波清洗設備使用時的頻率在很大程度上決定了超聲波清洗機的清洗效果。超聲波空化閾值與超聲波清洗機的頻率密切相關。頻率越高，氣蝕閥越高。也就是說：頻率越低越容易產生空化，而在頻率低的情況下，液體被壓縮變薄的時間間隔更長，這樣氣泡在解體前就可以長到更大的尺寸.因此，我們可以通過增加空化強度來提高清洗效率。

　　In general, the frequency of ultrasonic cleaning equipment to a large extent determines the cleaning effect of ultrasonic cleaning machine. Ultrasonic cavitation threshold is closely related to the frequency of ultrasonic cleaning machine. The higher the frequency, the higher the cavitation valve. That is: cavitation is more likely to occur at lower frequencies, and at lower frequencies, the liquid is compressed and thinned at longer intervals, allowing bubbles to grow to larger sizes before they disintegrate. Therefore, we can increase the cleaning efficiency by increasing the cavitation intensity.

　　盲孔太小，水壓無法使堵在盲孔中的氣泡爆裂。超聲波的傳播是以水為介質，即超聲波清洗機說只要水能到達的地方，超聲波就會存在，從而實現清洗。但少量未滲入清洗劑的盲孔無法清洗干凈。

　　The blind hole is too small for water pressure to burst the bubbles trapped in it. The transmission of ultrasonic is water as the medium, that is, ultrasonic cleaning machine said that as long as the water can reach the place, ultrasonic will exist, so as to achieve cleaning. However, a small number of blind holes that have not infiltrated into the cleaning agent cannot be cleaned.

　　超聲波清洗設備是一種新型的清洗技術，根據盲孔零件的結構特點和水性金屬表面清洗劑的使用，在超聲波清洗中引入真空技術，以達到更好的清洗效果。目前已廣泛應用于工業清洗領域。所以想知道更多的內容，就點擊http://www.chendakeji.cn網站咨詢！
