　　在工业生产上，工件清洗绝不是一个小环节。清洗方式的选择，直接关系到产品性能的稳定性与质量可靠性；选择不恰当的工艺，不仅会影响生产效率，还可能损伤工件的精密度，带来不必要的成本浪费。

　　In industrial production, workpiece cleaning is by no means a small step. The choice of cleaning method directly affects the stability and quality reliability of product performance; Choosing an inappropriate process not only affects production efficiency, but may also damage the precision of the workpiece, resulting in unnecessary cost waste.

　　清洗方式的选择，关键在于结合三个核心维度综合判断：

　　The key to choosing a cleaning method lies in the comprehensive judgment of three core dimensions:

　　三个维度

　　three dimensions

　　01工件结构复杂性

　　01 Complexity of workpiece structure

　　02污染物属性

　　02 Pollutant Attributes

　　03材料兼容性01

　　03 Material Compatibility 01

　　工件结构复杂性——结构复杂工件：  如带有盲孔、深孔、微细缝隙、复杂流道或精密纹路的工件，更适合采用超声波清洗。超声波依托“空化效应”，在清洗液中产生无数微米级气泡，可穿透并清洁人手难以触及的细小区域，实现无死角清洗。

　　Workpiece structural complexity - Workpieces with complex structures, such as blind holes, deep holes, micro gaps, complex flow channels, or precision patterns, are more suitable for ultrasonic cleaning. Ultrasonic waves rely on the "cavitation effect" to generate countless micrometer sized bubbles in the cleaning solution, which can penetrate and clean small areas that are difficult for human hands to reach, achieving blind spot free cleaning.

　　结构简单工件：  对于表面平整、开放性强、无隐藏结构或大型外表面工件，喷淋清洗是更高效经济的选择。系统通过不同角度的喷嘴喷射高速液流，凭借机械冲击力迅速剥离污垢，覆盖均匀，适合连续大批量作业。

　　Simple structured workpieces: For workpieces with flat surfaces, strong openness, no hidden structures, or large external surfaces, spray cleaning is a more efficient and economical choice. The system sprays high-speed liquid streams through nozzles at different angles, and quickly removes dirt with mechanical impact force, covering evenly and suitable for continuous large-scale operations.

　　02污染物的附着状态——嵌入式、微小的污染物：  如轻质油污、灰尘、冷却液残留等。可使用超声波清洗，其空化作用可使清洗液渗入微粒间隙，温和而彻底地瓦解污染物，尤其适合精密件和表面要求高的场合。

　　02 Adhesion status of pollutants - embedded, small pollutants such as light oil stains, dust, coolant residue, etc. Ultrasonic cleaning can be used, and its cavitation effect can allow the cleaning solution to penetrate into the gaps between particles, gently and thoroughly dissolving pollutants, especially suitable for precision parts and high surface requirements.

　　厚实、粘着力高的污垢：  如厚重油脂、抛光膏、积碳、胶质残留等，经济实惠上更推荐喷淋清洗，凭借其较强的冲击力和覆盖能力，更容易实现快速剥离。尤其在中高压喷淋模式下，清洗液对顽固污垢有良好的机械铲切作用。喷淋设备喷嘴需定期更换

　　Thick and highly adhesive dirt, such as heavy grease, polishing paste, carbon deposits, and gum residue, is more recommended for economical spray cleaning. With its strong impact and coverage ability, it is easier to achieve rapid peeling. Especially in the medium high pressure spray mode, the cleaning solution has a good mechanical cutting effect on stubborn dirt. Spray equipment nozzles need to be replaced regularly

　　复合型污染物 或 其他顽固污垢：  可采取组合清洗策略。例如先通过喷淋清除工件表面大部分重污垢，再借助超声波进行深度精细清洗，尤其适用于既有平坦表面又有复杂内腔的工件。

　　Composite pollutants or other stubborn dirt: a combination cleaning strategy can be adopted. For example, first remove most of the heavy dirt on the surface of the workpiece through spraying, and then use ultrasonic waves for deep and fine cleaning, especially suitable for workpieces with both flat surfaces and complex internal cavities.

　　03材料兼容性——精密脆弱材质：  对于表面易划伤、镀层脆弱或结构微小的工件（如精密电子元件、细小工件等），宜优先选择超声波清洗。但需注意控制超声功率和作用时间，避免空化作用导致表面微损伤。

　　03 Material Compatibility - Precision Fragile Materials: For workpieces with easily scratched surfaces, fragile coatings, or small structures (such as precision electronic components, small workpieces, etc.), ultrasonic cleaning should be preferred. However, it is important to control the ultrasound power and duration to avoid surface micro damage caused by cavitation.

　　坚硬及耐受性材料：  不锈钢、硬质合金等，可兼容喷淋清洗。但需注意喷射压力与距离的控制，过高压力仍可能对棱边或薄弱部位造成冲击损伤。

　　Hard and durable materials: stainless steel, hard alloy, etc., compatible with spray cleaning. However, attention should be paid to the control of injection pressure and distance, as excessive pressure may still cause impact damage to edges or weak areas.

　　化学兼容性考量：  无论超声波或喷淋，都需确保清洗剂与工件材料相容。例如某些清洗液可能对有色金属、橡胶或涂层有腐蚀性，需提前开展相容性测试，避免发生材料变质或失效。

　　Chemical compatibility considerations: Whether using ultrasound or spray, it is necessary to ensure that the cleaning agent is compatible with the workpiece material. For example, certain cleaning solutions may be corrosive to non-ferrous metals, rubber, or coatings, and compatibility testing should be conducted in advance to avoid material deterioration or failure.

　　总结  综上，超声波与喷淋清洗并无绝对优劣之分，关键要看应用场景和清洗要求。建议结合实际工件情况、预算成本、污染类型及产线节奏进行综合分析，必要时可结合两种技术实现更可靠、高效的清洗闭环。

　　In summary, there is no absolute superiority or inferiority between ultrasonic and spray cleaning, and the key depends on the application scenario and cleaning requirements. It is recommended to conduct a comprehensive analysis based on the actual workpiece situation, budget cost, pollution type, and production line rhythm. If necessary, two technologies can be combined to achieve a more reliable and efficient cleaning loop.
