全自动化喷淋清洗机凭借高压喷射与程序控制的协同作用，在工业零件清洁领域占据重要地位，其核心优势体现在各清洗环节的精准配合与高效运作。从预处理到干燥的全流程无需人工干预，通过压力、温度、时间的精准调控，实现对油污、碎屑、污渍的深度清除，满足不同材质、不同污染程度零件的清洁需求，各环节的功能特性共同构成了设备的高效清洁能力。

　　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.

　　预处理环节是清除表面浮尘与疏松杂质的基础步骤，为后续深度清洁奠定基础。该环节通过阵列式喷嘴形成 360 度无死角的喷淋区域，高压水流（压力通常在 0.8-2MPa）以扇形或锥形喷射模式冲击零件表面，利用水流的冲击力剥离附着的铁屑、砂粒、粉尘等固态杂质，以及部分可溶性油污。对于带有凹槽、通孔的复杂零件，设备会配备定向旋转喷嘴，水流可深入孔径内部，避免杂质在缝隙中藏匿。预处理的水温一般控制在 30-50℃，适度的温度能增强水流对油污的浸润效果，同时避免高温对零件表面造成损伤。经过预处理后，零件表面 80% 以上的疏松污染物被清除，大幅降低后续环节的清洁压力，减少清洗液的消耗。

　　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.

　　主清洗环节是瓦解顽固污渍的核心，通过高压与化学作用的协同实现深度清洁。此环节的喷射压力提升至 2-5MPa，部分针对重油污的场景可增至 8MPa，高压水流能穿透凝固的油脂层，使顽固油污产生龟裂并脱离零件表面。清洗液多采用碱性配方（pH 值 8-10），通过皂化反应将动植物油脂转化为可溶于水的物质，配合表面活性剂增强对矿物油的乳化能力，实现油污的化学分解。主清洗区域的水温通常设定在 50-70℃，高温环境能加速化学反应速率，同时降低清洗液的黏度，增强其渗透能力。为提升清洁均匀性，输送带在主清洗区域会采用步进式运行模式，即零件暂停时喷嘴集中喷射，确保每个部位都能获得足够的清洗时间。清洗液通过循环过滤系统持续净化，滤网与磁性分离器可截留液体中的固态杂质，使清洗液重复使用，降低运行成本。

　　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.

　　漂洗环节的核心作用是清除残留清洗液与化学物质，避免二次污染。经过主清洗的零件表面会附着少量含洗涤剂的液体，若不彻底清除，干燥后可能形成白色印记或腐蚀斑点。漂洗环节采用多级递进式清洁模式，一级漂洗使用经过过滤的循环水，初步冲洗大部分残留液；二级漂洗切换为纯水，通过更细密的喷嘴布局，清除零件表面及缝隙中残留的洗涤剂成分；对于精密零件（如液压阀块、轴承套），会增加三级去离子水漂洗，利用去离子水无矿物质的特性，防止水中离子在零件表面形成电化学腐蚀。漂洗压力略低于主清洗（1-3MPa），避免高压水流对已清洁的精密表面造成损伤，水温保持在 40-60℃，既能确保冲洗效果，又能减少水分在零件表面的附着量，为后续干燥环节减负。

　　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.
