在精密零部件的清洁领域，一个直径仅0.3mm的喷油嘴喷孔、一片涡轮叶片曲面夹角处的涂层残留、一枚石英晶振表面的微粒污染物，都可能成为影响产品性能的“明显缺陷”。多槽手动超声波清洗机正是为解决这类微米级清洁难题而生。

In the field of precision component cleaning, a nozzle hole with a diameter of only 0.3mm, coating residue at the angle of a turbine blade surface, and particulate pollutants on the surface of a quartz crystal oscillator can all become "fatal defects" that affect product performance. The multi slot manual ultrasonic cleaning machine is designed to solve this type of micron level cleaning problem.

多槽手动超声波清洗机的核心在于“分步”与“协同”。设备通常配备3-6个独立槽体，每个槽体可分别注入清水、专用清洗剂、防锈液等不同介质，形成预洗、主洗、漂洗、脱水等完整清洗流程。操作人员根据工件污染程度，依次将工件从预洗槽转移至后续槽体：预洗槽采用60℃碱性清洗剂去除工件表面90%以上切削液等大分子污染物；主洗槽配置40kHz超声波换能器，产生空化效应使清洗液形成微射流，深入0.1mm以下盲孔清除金属碎屑；漂洗槽使用去离子水进行三级逆流漂洗，电导率控制在5μS/cm以下；非常后在烘干槽完成表面干燥处理。

The core of a multi slot manual ultrasonic cleaning machine lies in "step-by-step" and "collaborative" approaches. Equipment is usually equipped with 3-6 independent tanks, each of which can be filled with different media such as clean water, specialized cleaning agents, rust inhibitors, etc., forming a complete cleaning process including pre washing, main washing, rinsing, dehydration, etc. The operator transfers the workpiece from the pre washing tank to the subsequent tank according to the degree of contamination: the pre washing tank uses a 60 ℃ alkaline cleaning agent to remove more than 90% of large molecular pollutants such as cutting fluid on the surface of the workpiece; The main washing tank is equipped with a 40kHz ultrasonic transducer, which generates cavitation effect to form micro jets of cleaning solution, penetrating into blind holes below 0.1mm to remove metal debris; The rinsing tank uses deionized water for three-stage countercurrent rinsing, with conductivity controlled below 5 μ S/cm; Finally, the surface drying treatment is completed in the drying tank.

多槽手动超声波清洗机非常突出的优势在于其灵活换液能力。针对机械零件的切削油污染，可在主洗槽更换中性除油剂；面对电子元件的助焊剂残留，换用专用环保清洗剂。每个槽体独立储液，清洗不同批次工件时可快速换液，防止交叉污染。对于直径5mm的喷油嘴清洗测试显示，超声波清洗使孔内残留物显著减少；涡轮叶片曲面夹角处的碳化钨涂层残留，通过超声波空化剥离技术可实现100%清除；在石英晶振清洗中，通过调整功率密度使碎片率从3.2%大幅降低。从发动机喷油嘴到航空涡轮叶片，多槽手动超声波清洗机正在用“分步协同”的智慧，攻克一个又一个精密清洗的“无人区”。

The most prominent advantage of the multi slot manual ultrasonic cleaning machine is its flexible liquid changing ability. For cutting oil pollution of mechanical parts, neutral degreaser can be replaced in the main washing tank; In the face of residual soldering flux in electronic components, switch to specialized environmentally friendly cleaning agents. Each tank is independently stored with liquid, and the liquid can be quickly changed when cleaning different batches of workpieces to prevent cross contamination. The cleaning test for a 5mm diameter fuel injector showed that ultrasonic cleaning significantly reduced the residue inside the hole; The residual tungsten carbide coating at the angle of the turbine blade surface can be completely removed by ultrasonic cavitation stripping technology; In quartz crystal oscillator cleaning, the fragment rate was significantly reduced from 3.2% by adjusting the power density. From engine fuel injectors to aviation turbine blades, multi slot manual ultrasonic cleaning machines are using the wisdom of "step-by-step collaboration" to conquer one precision cleaning "no man's land" after another.
