全自動化噴淋清洗機憑借高壓噴射與程序控制的協同作用，在工業零件清潔領域占據重要地位，其核心優勢體現在各清洗環節的精準配合與高效運作。從預處理到干燥的全流程無需人工干預，通過壓力、溫度、時間的精準調控，實現對油污、碎屑、污漬的深度清除，滿足不同材質、不同污染程度零件的清潔需求，各環節的功能特性共同構成了設備的高效清潔能力。

　　The fully automated spray cleaning machine, with the synergistic effect of high-pressure spraying and program control, occupies an important position in the field of industrial parts cleaning. Its core advantages are reflected in the precise coordination and efficient operation of each cleaning process. The entire process from pretreatment to drying does not require manual intervention. Through precise control of pressure, temperature, and time, it achieves deep removal of oil stains, debris, and dirt, meeting the cleaning needs of parts of different materials and pollution levels. The functional characteristics of each link together constitute the efficient cleaning capability of the equipment.

　　預處理環節是清除表面浮塵與疏松雜質的基礎步驟，為后續深度清潔奠定基礎。該環節通過陣列式噴嘴形成 360 度無死角的噴淋區域，高壓水流（壓力通常在 0.8-2MPa）以扇形或錐形噴射模式沖擊零件表面，利用水流的沖擊力剝離附著的鐵屑、砂粒、粉塵等固態雜質，以及部分可溶性油污。對于帶有凹槽、通孔的復雜零件，設備會配備定向旋轉噴嘴，水流可深入孔徑內部，避免雜質在縫隙中藏匿。預處理的水溫一般控制在 30-50℃，適度的溫度能增強水流對油污的浸潤效果，同時避免高溫對零件表面造成損傷。經過預處理后，零件表面 80% 以上的疏松污染物被清除，大幅降低后續環節的清潔壓力，減少清洗液的消耗。

　　The preprocessing stage is the fundamental step in removing surface dust and loose impurities, laying the foundation for subsequent deep cleaning. This process forms a 360 degree spray area without dead corners through an array of nozzles. High pressure water flow (usually at a pressure of 0.8-2MPa) impacts the surface of the parts in a fan-shaped or conical spray mode, using the impact force of the water flow to peel off solid impurities such as iron filings, sand particles, dust, and some soluble oil stains. For complex parts with grooves and through holes, the equipment will be equipped with directional rotating nozzles, allowing water flow to penetrate deep into the aperture to prevent impurities from hiding in the gaps. The pre-treatment water temperature is generally controlled at 30-50 ℃. Moderate temperature can enhance the infiltration effect of water flow on oil stains, while avoiding damage to the surface of parts caused by high temperature. After pre-treatment, more than 80% of the loose pollutants on the surface of the parts are removed, significantly reducing the cleaning pressure in subsequent processes and reducing the consumption of cleaning solution.

　　主清洗環節是瓦解頑固污漬的核心，通過高壓與化學作用的協同實現深度清潔。此環節的噴射壓力提升至 2-5MPa，部分針對重油污的場景可增至 8MPa，高壓水流能穿透凝固的油脂層，使頑固油污產生龜裂并脫離零件表面。清洗液多采用堿性配方（pH 值 8-10），通過皂化反應將動植物油脂轉化為可溶于水的物質，配合表面活性劑增強對礦物油的乳化能力，實現油污的化學分解。主清洗區域的水溫通常設定在 50-70℃，高溫環境能加速化學反應速率，同時降低清洗液的黏度，增強其滲透能力。為提升清潔均勻性，輸送帶在主清洗區域會采用步進式運行模式，即零件暫停時噴嘴集中噴射，確保每個部位都能獲得足夠的清洗時間。清洗液通過循環過濾系統持續凈化，濾網與磁性分離器可截留液體中的固態雜質，使清洗液重復使用，降低運行成本。

　　The main cleaning process is the core of breaking down stubborn stains, achieving deep cleaning through the synergy of high pressure and chemical action. The spray pressure in this stage can be increased to 2-5MPa, and for some scenarios with heavy oil stains, it can be increased to 8MPa. High pressure water flow can penetrate the solidified oil layer, causing stubborn oil stains to crack and detach from the surface of the parts. Cleaning solutions often use alkaline formulas (pH 8-10) to convert animal and vegetable oils into water-soluble substances through saponification reactions, combined with surfactants to enhance the emulsifying ability of mineral oils and achieve chemical decomposition of oil stains. The water temperature in the main cleaning area is usually set at 50-70 ℃. High temperature environment can accelerate the chemical reaction rate, while reducing the viscosity of the cleaning solution and enhancing its permeability. To improve cleaning uniformity, the conveyor belt will adopt a step-by-step operation mode in the main cleaning area, which means that the nozzles will spray intensively when the parts are paused, ensuring that each part can receive sufficient cleaning time. The cleaning solution is continuously purified through a circulating filtration system, and the filter screen and magnetic separator can intercept solid impurities in the liquid, making the cleaning solution reusable and reducing operating costs.

　　漂洗環節的核心作用是清除殘留清洗液與化學物質，避免二次污染。經過主清洗的零件表面會附著少量含洗滌劑的液體，若不徹底清除，干燥后可能形成白色印記或腐蝕斑點。漂洗環節采用多級遞進式清潔模式，一級漂洗使用經過過濾的循環水，初步沖洗大部分殘留液；二級漂洗切換為純水，通過更細密的噴嘴布局，清除零件表面及縫隙中殘留的洗滌劑成分；對于精密零件（如液壓閥塊、軸承套），會增加三級去離子水漂洗，利用去離子水無礦物質的特性，防止水中離子在零件表面形成電化學腐蝕。漂洗壓力略低于主清洗（1-3MPa），避免高壓水流對已清潔的精密表面造成損傷，水溫保持在 40-60℃，既能確保沖洗效果，又能減少水分在零件表面的附著量，為后續干燥環節減負。

　　The core function of the rinsing process is to remove residual cleaning solution and chemicals, avoiding secondary pollution. After the main cleaning, a small amount of detergent containing liquid may adhere to the surface of the parts. If not thoroughly removed, white marks or corrosion spots may form after drying. The rinsing process adopts a multi-stage progressive cleaning mode, with the first stage rinsing using filtered circulating water to preliminarily rinse most of the residual liquid; Switching from secondary rinsing to pure water, using a finer nozzle layout to remove residual detergent components from the surface and gaps of the parts; For precision parts such as hydraulic valve blocks and bearing sleeves, three-stage deionized water rinsing will be added to utilize the mineral free nature of deionized water to prevent electrochemical corrosion of water ions on the surface of the parts. The rinsing pressure is slightly lower than the main cleaning pressure (1-3MPa) to avoid damage to the cleaned precision surface caused by high-pressure water flow. The water temperature is maintained at 40-60 ℃, which can ensure the rinsing effect and reduce the amount of water adhering to the surface of the parts, reducing the burden on the subsequent drying process.
