超聲波清洗機工作頻率及清洗液的重要性

超聲波清洗機工作頻率

Working frequency of ultrasonic cleaning machine

當工作頻率非常低（在人類聽覺范圍內）時，就會出現噪音。當頻率低于20kHz時，工作噪聲不僅變大，而且可能超過職業安全衛生法或其他法規規定的安全噪聲限值。在需要高功率去除污垢而不擔心損壞工件表面的應用中，通常選擇從20kHz到30kHz的較低清潔頻率。此頻率范圍內的清潔頻率通常用于清潔大型、重型零件或具有高密度材料的工件。20KHz磁性換能器和25KHz壓電換能器。

Noise occurs when the operating frequency is very low (within the range of human hearing). When the frequency is lower than 20kHz, the working noise not only becomes larger, but also may exceed the safety noise limit specified by the occupational safety and health law or other regulations. In applications that require high power to remove dirt without fear of damaging the workpiece surface, a lower cleaning frequency from 20kHz to 30kHz is usually selected. The cleaning frequency within this frequency range is usually used to clean large, heavy parts or workpieces with high-density materials. 20kHz magnetic transducer and 25kHz piezoelectric transducer.

高頻通常用于清潔更小、更精細的部件，或去除微小顆粒。高頻也用于不允許損壞工件表面的應用中。使用高頻可以通過多種方式提高清潔性能。隨著頻率的增加，空化氣泡的數量線性增加，產生更多更密集的沖擊波，可以穿透更小的間隙。如果功率不變，空化氣泡變小，其釋放的能量也相應減少，有效減少了對工件表面的損傷。高頻的另一個優點是它減少了粘性邊界層（波努利效應），使超聲波能夠檢測到極細的顆粒。這種情況類似于在水位下降時看到小溪底部的小鵝卵石。

High frequency is usually used to clean smaller and finer parts or remove small particles. High frequency is also used in applications where damage to the workpiece surface is not allowed. Using high frequency can improve cleaning performance in many ways. With the increase of frequency, the number of cavitation bubbles increases linearly, producing more and more dense shock waves, which can penetrate smaller gaps. If the power is constant, the cavitation bubble becomes smaller, and the energy released by it is reduced accordingly, which effectively reduces the damage to the workpiece surface. Another advantage of high frequency is that it reduces the viscous boundary layer (Bernoulli effect), enabling ultrasound to detect very fine particles. This is similar to seeing the pebbles at the bottom of the stream when the water level drops.

超聲波清洗機清洗液

超聲波清洗機生產廠家提醒您，不同的清洗液，清洗系統水基系統要加以區分：通常由一個開口槽組成，工件浸沒在其中。復雜的系統由多個水箱組成，并配有循環過濾系統、淋浴水箱、干燥箱等配件。溶劑系統多為超聲波汽相脫脂清洗機，常配備連續廢液回收裝置。

The manufacturer of ultrasonic cleaning machine reminds you that the water-based system of cleaning system should be distinguished for different cleaning solutions: it is usually composed of an open groove in which the workpiece is immersed. The complex system consists of multiple water tanks, and is equipped with circulating filtration system, shower water tank, drying oven and other accessories. Solvent systems are mostly ultrasonic vapor degreasing cleaning machines, often equipped with continuous waste liquid recovery devices.

超聲波汽相去除油脂是由溶劑蒸發罐和超聲波浸漬罐組成的一體化多罐系統完成的。油、油脂、蠟和其他溶劑可溶性污垢通過結合使用熱溶劑蒸汽和超聲波攪拌來去除。經過一系列清洗工序后卸出的工件是熱的、干凈的、干燥的。

Ultrasonic vapor phase grease removal is completed by an integrated multi tank system composed of solvent evaporation tank and ultrasonic impregnation tank. Oil, grease, wax and other solvent soluble dirt are removed by a combination of hot solvent steam and ultrasonic stirring. The workpiece unloaded after a series of cleaning procedures is hot, clean and dry.

此外廉價的清洗溶劑的使用成本并不一定低。使用中必須考慮到溶劑的清洗效率、安全性、一定量的溶劑可清洗多少工件利用率高等因素。當然，所選擇的清洗溶劑必須達到清洗效果，并應與所清洗的工件材料相容。更多相關內容就來關注我們網站www.dijiushangdian.cn吧！

In addition, the cost of using cheap cleaning solvents is not necessarily low. The cleaning efficiency and safety of the solvent, the number of workpieces that can be cleaned with a certain amount of solvent, and the high utilization rate must be considered in the use. Of course, the selected cleaning solvent must achieve the cleaning effect and be compatible with the workpiece material to be cleaned. Let's pay more attention to our website!
