超聲波清洗機(jī)頻率并非越高越好，選對才實(shí)用

　　The higher the frequency of the ultrasonic cleaning machine, the better. Choosing the right one is practical

　　在山東電氣成套設(shè)備的配置中，變壓器作為電力轉(zhuǎn)換的核心部件，其配套的高壓進(jìn)線開關(guān)選型直接關(guān)系到設(shè)備安全和運(yùn)行穩(wěn)定性。不少企業(yè)采購或運(yùn)維山東電氣成套設(shè)備時，都會困惑：多大容量的變壓器該用負(fù)荷開關(guān)，多大的該用斷路器？負(fù)荷開關(guān)與熔斷器又適配哪些情況？其實(shí)答案很明確，核心就是看變壓器的容量大小。今天就專門圍繞這個問題科普，幫大家理清不同容量變壓器對應(yīng)的開關(guān)選型邏輯。

　　In the configuration of Shandong Electric's complete set of equipment, transformers are the core components of power conversion, and the selection of their matching high-voltage incoming line switches directly affects the safety and operational stability of the equipment. Many companies are confused when purchasing or operating complete sets of equipment from Shandong Electric: what capacity transformer should use a load switch, and what size should use a circuit breaker? What are the suitable situations for load switches and fuses? The answer is actually very clear, the core is to look at the capacity of the transformer. Today, we will focus on this topic to popularize science and help everyone clarify the switch selection logic corresponding to transformers of different capacities.

　　先說說低頻段（20-40kHz），這是專門應(yīng)對“粗洗、重污”的高頻段。它的核心優(yōu)勢是空化效應(yīng)強(qiáng)，產(chǎn)生的氣泡破裂時沖擊力大，能快速剝離工件表面的厚重油污、銹蝕層和大顆粒雜質(zhì)。比如機(jī)械加工后的零件、五金配件上的切削油垢、長期使用的模具表面重污，用低頻清洗都能高效搞定。不過要注意，低頻清洗的沖擊力較強(qiáng)，清洗后工件表面可能殘留輕微痕跡，所以更適合預(yù)處理環(huán)節(jié)，或者對潔凈度要求不高的工業(yè)場景。如果用低頻清洗精密脆弱的工件，很容易造成表面劃傷或結(jié)構(gòu)損壞。

　　First, let's talk about the low-frequency range (20-40kHz), which is specifically designed to deal with the high-frequency range of "coarse washing and heavy pollution". Its core advantage is strong cavitation effect, which generates bubbles with strong impact force when they burst, and can quickly peel off heavy oil stains, rust layers, and large particle impurities on the surface of the workpiece. For example, cutting oil stains on machined parts, hardware accessories, and heavily soiled mold surfaces that have been used for a long time can be efficiently cleaned with low-frequency cleaning. However, it should be noted that low-frequency cleaning has a strong impact force, and there may be slight traces left on the surface of the workpiece after cleaning, so it is more suitable for pre-treatment or industrial scenarios with low cleanliness requirements. If low-frequency cleaning is used to clean delicate and fragile workpieces, it is easy to cause surface scratches or structural damage.

　　再看中頻段（60-80kHz），這是應(yīng)用最廣的“通用型”頻率，也是大多數(shù)場景的穩(wěn)妥選擇。它很好地平衡了清洗力度和工件保護(hù)，既能有效去除常規(guī)污漬，又不會損傷工件。不管是五金小配件、電子元件的表面灰塵油污，還是汽車零件、醫(yī)療器械的常規(guī)清潔，選中頻基本不會出錯。比如電子廠清洗電路板、汽修店清洗發(fā)動機(jī)零件、醫(yī)院清洗常規(guī)醫(yī)療器械，中頻段都能滿足潔凈度要求，而且適配的工件材質(zhì)范圍廣，不銹鋼、塑料、玻璃等都能適用，性價比也相對較高，是工業(yè)和商業(yè)場景的主流選擇。

　　Looking at the mid frequency range (60-80kHz), it is the most widely used "universal" frequency and a reliable choice for most scenarios. It strikes a good balance between cleaning force and workpiece protection, effectively removing common stains without damaging the workpiece. Whether it's the surface dust and oil stains of hardware accessories and electronic components, or the routine cleaning of automotive parts and medical equipment, the selection frequency is basically error free. For example, cleaning circuit boards in electronic factories, cleaning engine parts in auto repair shops, and cleaning conventional medical equipment in hospitals can all meet cleanliness requirements in the mid frequency range. Moreover, it can adapt to a wide range of workpiece materials, such as stainless steel, plastic, glass, etc., with relatively high cost-effectiveness, making it the mainstream choice in industrial and commercial scenarios.

　　最后是高頻段（100-130kHz），主打“精密清洗、細(xì)小微粒去除”，適合對潔凈度要求極高的場景。高頻產(chǎn)生的空化氣泡更小、分布更均勻，能深入到工件的微小縫隙、微孔和盲孔內(nèi)部清洗，而且沖擊力溫和，不會劃傷脆弱工件表面。比如光學(xué)鏡片、半導(dǎo)體元件、精密儀器的核心零件，這些工件材質(zhì)脆弱、結(jié)構(gòu)復(fù)雜，污漬多是細(xì)小微粒，用高頻清洗既能徹底去除污漬，又能保護(hù)工件精度。但要注意，高頻清洗力度較弱，對付厚重油污時效率很低，甚至洗不干凈，所以絕對不能用高頻來處理重污工件。

　　Finally, the high frequency range (100-130kHz) focuses on "precision cleaning and removal of fine particles", suitable for scenarios with extremely high cleanliness requirements. The cavitation bubbles generated by high frequency are smaller and more evenly distributed, and can penetrate deep into the tiny gaps, micropores, and blind holes of the workpiece for cleaning. Moreover, the impact force is mild and will not scratch the surface of fragile workpieces. For example, optical lenses, semiconductor components, and core parts of precision instruments are made of fragile materials and have complex structures. Stains are mostly small particles, and high-frequency cleaning can thoroughly remove stains while protecting the accuracy of the workpiece. However, it should be noted that high-frequency cleaning has weak cleaning force and low efficiency in dealing with heavy oil stains, and even cannot clean thoroughly. Therefore, high-frequency cleaning should never be used to treat heavily polluted workpieces.

　　還有個實(shí)用技巧要分享：如果遇到復(fù)雜的清洗需求，比如工件既要去除重污又要達(dá)到高潔凈度，可以選擇多槽超聲波清洗機(jī)，采用“多頻組合”的方式。簡單說就是先通過低頻槽粗洗，快速剝離重油污和大顆粒雜質(zhì)；再進(jìn)入高頻槽精洗，去除細(xì)小微粒、提升潔凈度；必要時中間還可增加中頻槽過渡清洗，確保清洗效果。這種組合方式能兼顧效率和精度，適合精密機(jī)械制造、高端電子等對清洗要求嚴(yán)格的行業(yè)。

　　There is another practical technique to share: If you encounter complex cleaning needs, such as removing heavy stains from workpieces while achieving high cleanliness, you can choose a multi slot ultrasonic cleaning machine and use a "multi frequency combination" method. Simply put, it means first rough washing through a low-frequency tank to quickly remove heavy oil stains and large particle impurities; Then enter the high-frequency tank for fine cleaning to remove small particles and improve cleanliness; If necessary, intermediate frequency slot transition cleaning can be added in the middle to ensure the cleaning effect. This combination method can balance efficiency and accuracy, making it suitable for industries with strict cleaning requirements such as precision machinery manufacturing and high-end electronics.

　　給大家提個核心選型建議：選超聲波清洗機(jī)頻率時，先明確兩個關(guān)鍵信息--工件的污漬類型（是重油污、大顆粒，還是細(xì)小微粒）和工件材質(zhì)（是堅固的金屬，還是脆弱的光學(xué)玻璃、半導(dǎo)體）。按“重污選低頻、常規(guī)選中頻、精密選高頻”的原則來選，再結(jié)合實(shí)際需求判斷是否需要多頻組合。千萬別盲目追求高頻率，比如用130kHz的高頻清洗重油污零件，不僅效率低，還會浪費(fèi)電力；反過來用20kHz的低頻清洗光學(xué)鏡片，很可能直接劃傷鏡片。

　　Here's a core selection suggestion for everyone: When choosing the frequency of an ultrasonic cleaning machine, first clarify two key information - the type of stain on the workpiece (heavy oil stains, large particles, or small particles) and the material of the workpiece (strong metal, fragile optical glass, semiconductor). Choose according to the principle of "selecting low frequency for heavy pollution, medium frequency for conventional use, and high frequency for precision", and then determine whether multi frequency combination is needed based on actual needs. Do not blindly pursue high frequencies, such as using 130kHz high frequency to clean heavy oil contaminated parts, which not only has low efficiency but also wastes electricity; Conversely, cleaning optical lenses with a low frequency of 20kHz may directly scratch the lenses.

　　總結(jié)下來，超聲波清洗機(jī)的頻率選擇核心是“匹配需求”，低頻強(qiáng)沖擊適粗洗、中頻通用適配廣、高頻高精度適精洗，頻率高低沒有絕對優(yōu)劣。掌握這個選型邏輯，就能根據(jù)自己的工件情況精準(zhǔn)選對頻率，既保證清洗效果，又能保護(hù)工件、提升效率。如果大家在具體選型時還有疑問，比如不確定某類工件該選哪個頻率，建議咨詢清洗機(jī)廠家，結(jié)合工件樣品和清洗要求獲取精準(zhǔn)建議，避免踩坑。

　　In summary, the core of frequency selection for ultrasonic cleaning machines is "matching requirements". Low frequency strong impact is suitable for rough cleaning, medium frequency universal adaptation is wide, and high frequency high-precision is suitable for fine cleaning. There is no absolute superiority or inferiority in frequency. By mastering this selection logic, one can accurately select the right frequency based on their own workpiece situation, ensuring both cleaning effectiveness and protecting the workpiece while improving efficiency. If you still have doubts about the specific selection, such as unsure which frequency to choose for a certain type of workpiece, it is recommended to consult the cleaning machine manufacturer and obtain accurate advice based on the workpiece sample and cleaning requirements to avoid pitfalls.
