超声波清洗机频率并非越高越好，选对才实用

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

　　在山东电气成套设备的配置中，变压器作为电力转换的核心部件，其配套的高压进线开关选型直接关系到设备安全和运行稳定性。不少企业采购或运维山东电气成套设备时，都会困惑：多大容量的变压器该用负荷开关，多大的该用断路器？负荷开关与熔断器又适配哪些情况？其实答案很明确，核心就是看变压器的容量大小。今天就专门围绕这个问题科普，帮大家理清不同容量变压器对应的开关选型逻辑。

　　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.

　　先说说低频段（20-40kHz），这是专门应对“粗洗、重污”的高频段。它的核心优势是空化效应强，产生的气泡破裂时冲击力大，能快速剥离工件表面的厚重油污、锈蚀层和大颗粒杂质。比如机械加工后的零件、五金配件上的切削油垢、长期使用的模具表面重污，用低频清洗都能高效搞定。不过要注意，低频清洗的冲击力较强，清洗后工件表面可能残留轻微痕迹，所以更适合预处理环节，或者对洁净度要求不高的工业场景。如果用低频清洗精密脆弱的工件，很容易造成表面划伤或结构损坏。

　　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.

　　再看中频段（60-80kHz），这是应用最广的“通用型”频率，也是大多数场景的稳妥选择。它很好地平衡了清洗力度和工件保护，既能有效去除常规污渍，又不会损伤工件。不管是五金小配件、电子元件的表面灰尘油污，还是汽车零件、医疗器械的常规清洁，选中频基本不会出错。比如电子厂清洗电路板、汽修店清洗发动机零件、医院清洗常规医疗器械，中频段都能满足洁净度要求，而且适配的工件材质范围广，不锈钢、塑料、玻璃等都能适用，性价比也相对较高，是工业和商业场景的主流选择。

　　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.

　　最后是高频段（100-130kHz），主打“精密清洗、细小微粒去除”，适合对洁净度要求极高的场景。高频产生的空化气泡更小、分布更均匀，能深入到工件的微小缝隙、微孔和盲孔内部清洗，而且冲击力温和，不会划伤脆弱工件表面。比如光学镜片、半导体元件、精密仪器的核心零件，这些工件材质脆弱、结构复杂，污渍多是细小微粒，用高频清洗既能彻底去除污渍，又能保护工件精度。但要注意，高频清洗力度较弱，对付厚重油污时效率很低，甚至洗不干净，所以绝对不能用高频来处理重污工件。

　　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.

　　还有个实用技巧要分享：如果遇到复杂的清洗需求，比如工件既要去除重污又要达到高洁净度，可以选择多槽超声波清洗机，采用“多频组合”的方式。简单说就是先通过低频槽粗洗，快速剥离重油污和大颗粒杂质；再进入高频槽精洗，去除细小微粒、提升洁净度；必要时中间还可增加中频槽过渡清洗，确保清洗效果。这种组合方式能兼顾效率和精度，适合精密机械制造、高端电子等对清洗要求严格的行业。

　　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.

　　给大家提个核心选型建议：选超声波清洗机频率时，先明确两个关键信息--工件的污渍类型（是重油污、大颗粒，还是细小微粒）和工件材质（是坚固的金属，还是脆弱的光学玻璃、半导体）。按“重污选低频、常规选中频、精密选高频”的原则来选，再结合实际需求判断是否需要多频组合。千万别盲目追求高频率，比如用130kHz的高频清洗重油污零件，不仅效率低，还会浪费电力；反过来用20kHz的低频清洗光学镜片，很可能直接划伤镜片。

　　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.

　　总结下来，超声波清洗机的频率选择核心是“匹配需求”，低频强冲击适粗洗、中频通用适配广、高频高精度适精洗，频率高低没有绝对优劣。掌握这个选型逻辑，就能根据自己的工件情况精准选对频率，既保证清洗效果，又能保护工件、提升效率。如果大家在具体选型时还有疑问，比如不确定某类工件该选哪个频率，建议咨询清洗机厂家，结合工件样品和清洗要求获取精准建议，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.
