　　在工業生產上，工件清洗絕不是一個小環節。清洗方式的選擇，直接關系到產物性能的穩定性與質量可靠性；選擇不恰當的工藝，不僅會影響生產效率，還可能損傷工件的精密度，帶來不必要的成本浪費。

　　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.

　　清洗方式的選擇，關鍵在于結合叁個核心維度綜合判斷：

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

　　叁個維度

　　three dimensions

　　01工件結構復雜性

　　01 Complexity of workpiece structure

　　02污染物屬性

　　02 Pollutant Attributes

　　03材料兼容性01

　　03 Material Compatibility 01

　　工件結構復雜性——結構復雜工件：  如帶有盲孔、深孔、微細縫隙、復雜流道或精密紋路的工件，更適合采用超聲波清洗。超聲波依托“空化效應”，在清洗液中產生無數微米級氣泡，可穿透并清潔人手難以觸及的細小區域，實現無死角清洗。

　　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.

　　結構簡單工件：  對于表面平整、開放性強、無隱藏結構或大型外表面工件，噴淋清洗是更高效經濟的選擇。系統通過不同角度的噴嘴噴射高速液流，憑借機械沖擊力迅速剝離污垢，覆蓋均勻，適合連續大批量作業。

　　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污染物的附著狀態——嵌入式、微小的污染物：  如輕質油污、灰塵、冷卻液殘留等。可使用超聲波清洗，其空化作用可使清洗液滲入微粒間隙，溫和而徹底地瓦解污染物，尤其適合精密件和表面要求高的場合。

　　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.

　　厚實、粘著力高的污垢：  如厚重油脂、拋光膏、積碳、膠質殘留等，經濟實惠上更推薦噴淋清洗，憑借其較強的沖擊力和覆蓋能力，更容易實現快速剝離。尤其在中高壓噴淋模式下，清洗液對頑固污垢有良好的機械鏟切作用。噴淋設備噴嘴需定期更換

　　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

　　復合型污染物 或 其他頑固污垢：  可采取組合清洗策略。例如先通過噴淋清除工件表面大部分重污垢，再借助超聲波進行深度精細清洗，尤其適用于既有平坦表面又有復雜內腔的工件。

　　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——精密脆弱材質：  對于表面易劃傷、鍍層脆弱或結構微小的工件（如精密電子元件、細小工件等），宜優先選擇超聲波清洗。但需注意控制超聲功率和作用時間，避免空化作用導致表面微損傷。

　　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.

　　堅硬及耐受性材料：  不銹鋼、硬質合金等，可兼容噴淋清洗。但需注意噴射壓力與距離的控制，過高壓力仍可能對棱邊或薄弱部位造成沖擊損傷。

　　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.

　　化學兼容性考量：  無論超聲波或噴淋，都需確保清洗劑與工件材料相容。例如某些清洗液可能對有色金屬、橡膠或涂層有腐蝕性，需提前開展相容性測試，避免發生材料變質或失效。

　　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.

　　總結  綜上，超聲波與噴淋清洗并無絕對優劣之分，關鍵要看應用場景和清洗要求。建議結合實際工件情況、預算成本、污染類型及產線節奏進行綜合分析，必要時可結合兩種技術實現更可靠、高效的清洗閉環。

　　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.
