通过式喷淋清洗机的选型，采购方通常盯着传送速度、喷嘴数量、烘干温度这些"看得见"的参数。但真正决定清洗效果的，往往是三个容易被忽略的"水"参数：水温、水质、水压。

When selecting a spray cleaning machine, the purchaser usually focuses on visible parameters such as conveying speed, number of nozzles, and drying temperature. But what really determines the cleaning effect are often three easily overlooked "water" parameters: water temperature, water quality, and water pressure.

水温低一度，清洗剂效果差一截。

The water temperature is one degree lower, and the effectiveness of the cleaning agent is poor.

水基清洗剂的活性对温度非常敏感。大多数工业清洗剂的非常佳工作温度在50-70℃之间。低于这个区间，清洗剂对油污的乳化和分散能力明显下降；高于这个区间，部分清洗剂会分解失效或挥发加快，反而增加消耗。实际运行中常见的问题是：清洗槽加热功率配得够，但保温没做好，工件进槽后水温快速下降，后段工件实际是在"温水"里过了一遍。选型时要确认加热功率和保温层厚度，运行中要监测槽液实际温度，不是看温控表显示多少就是多少。

The activity of water-based cleaning agents is highly sensitive to temperature. The optimal working temperature for most industrial cleaning agents is between 50-70 ℃. Below this range, the emulsifying and dispersing ability of the cleaning agent on oil stains significantly decreases; Beyond this range, some cleaning agents may decompose and become ineffective or evaporate more quickly, resulting in increased consumption. A common problem in actual operation is that the heating power of the cleaning tank is sufficient, but the insulation is not done well. After the workpiece enters the tank, the water temperature drops rapidly, and the later stage of the workpiece is actually immersed in "warm water". When selecting, it is necessary to confirm the heating power and insulation layer thickness. During operation, the actual temperature of the tank solution should be monitored, not just the temperature displayed on the temperature control meter.

水质不控制，漂洗等于白洗。

If the water quality is not controlled, rinsing is equivalent to washing white.

漂洗段的目的不是"冲一下"，而是把工件表面残留的清洗剂和污垢带走。如果漂洗水本身杂质含量高，漂洗完工件表面还会留下水垢或离子残留。精密件清洗通常要求漂洗水电导率低于10μS/cm，有些场景要求更低。达到这个标准需要配纯水系统，不是接自来水就能用。多级逆流漂洗的设计逻辑就是：非常后一级用非常干净的水，逐级往前回流，既保证漂洗效果又节约用水。选型时要问清楚漂洗级数和纯水系统的配置。

The purpose of the rinsing stage is not to 'rinse', but to remove any residual cleaning agents and dirt from the surface of the workpiece. If the rinsing water itself has a high impurity content, scale or ion residue will still be left on the surface of the workpiece after rinsing. Precision parts cleaning usually requires a rinse water conductivity of less than 10 μ S/cm, and some scenarios require even lower conductivity. To meet this standard, a pure water system is required, which cannot be used simply by connecting to tap water. The design logic of multi-stage countercurrent rinsing is to use the cleanest water in the last stage and reflux forward step by step, which ensures the rinsing effect and saves water. When selecting, it is important to clarify the rinsing stage and the configuration of the pure water system.

水压不是越大越好，要看喷嘴类型和工件形状。

The higher the water pressure, the better. It depends on the type of nozzle and the shape of the workpiece.

高压喷淋适合去除顽固污垢和复杂型面，但压力太高会损伤精密工件表面，还可能把污垢冲进盲孔深处。低压大流量喷淋适合表面清洗和易损工件。喷嘴类型也直接影响压力分布：扇形喷嘴覆盖面积大但冲击力分散，锥形喷嘴冲击力集中但覆盖面小。选型时要根据工件的污染类型和形状来匹配压力和喷嘴，不是统一按非常高压力配。

High pressure spraying is suitable for removing stubborn dirt and complex surfaces, but too high pressure can damage the surface of precision workpieces and may also flush dirt into the depths of blind holes. Low pressure high flow spray is suitable for surface cleaning and vulnerable workpieces. The nozzle type also directly affects the pressure distribution: fan-shaped nozzles have a large coverage area but dispersed impact force, while conical nozzles have concentrated impact force but small coverage area. When selecting, the pressure and nozzle should be matched according to the pollution type and shape of the workpiece, not uniformly based on the highest pressure.

过滤系统是"水参数"的守护者。

The filtration system is the guardian of 'water parameters'.

清洗过程中剥离下来的污垢混入槽液，如果不及时过滤，会随喷淋再次打到工件表面。多级过滤（袋式、磁性、精密）配合使用才能保证槽液洁净度。滤芯更换要按压差表来，达到设定值就换，不能凭感觉。过滤系统堵了，水压会下降，清洗效果跟着打折。

The dirt peeled off during the cleaning process mixed into the tank solution. If not filtered in time, it will be sprayed onto the surface of the workpiece again. Multi level filtration (bag type, magnetic, precision) can be used in combination to ensure the cleanliness of the tank solution. The replacement of the filter element should be done by pressing the differential gauge and replacing it when it reaches the set value, not by feeling. The filtration system is blocked, the water pressure will decrease, and the cleaning effect will be reduced accordingly.

通过式喷淋清洗机的选型逻辑很清晰：水温按清洗剂非常佳活性区间控制，水质按工件清洁度要求配纯水，水压按污染类型和工件形状匹配，过滤系统保证槽液长期稳定。传送速度是骨架，水参数才是血肉。

The selection logic of the through type spray cleaning machine is very clear: the water temperature is controlled according to the optimal activity range of the cleaning agent, the water quality is matched with pure water according to the cleanliness requirements of the workpiece, the water pressure is matched according to the type of pollution and the shape of the workpiece, and the filtration system ensures long-term stability of the tank liquid. The transmission speed is the skeleton, water parameters are the flesh and blood.
