通过式喷淋清洗机在流水线上的定位很清楚：工件从一端进，经过预洗、主洗、漂洗、烘干，从另一端出来。听起来简单，但选型时非常容易被忽略的参数——节拍——直接决定这条清洗线能不能匹配前道和后道的产能。

The positioning of the spray cleaning machine on the assembly line is very clear: the workpiece enters from one end, goes through pre washing, main washing, rinsing, and drying, and exits from the other end. It sounds simple, but the most easily overlooked parameter when selecting - the beat - directly determines whether this cleaning line can match the production capacity of the front and rear channels.

节拍不是传送带速度，是清洗工艺的总时间。

The beat is not the speed of the conveyor belt, but the total time of the cleaning process.

很多采购方只问“传送带跑多快”，忽略了清洗效果取决于工件在清洗腔内的有效停留时间。预洗要冲掉大部分切削液和铁屑，主洗要针对盲孔和复杂型面做深度清洁，漂洗要控制残留电导率，烘干要保证水分不残留。每个工段的停留时间都有工艺下限，加起来才是真正的节拍底线。传送带走快了，工件经过喷淋区的时间不够，洗出来的东西表面看着干净，盲孔里还是油。

Many buyers only ask 'how fast the conveyor belt runs', ignoring that the cleaning effect depends on the effective residence time of the workpiece in the cleaning chamber. Pre washing should flush away most of the cutting fluid and iron filings, while main washing should perform deep cleaning on blind holes and complex surfaces. Rinsing should control residual conductivity, and drying should ensure that there is no residual moisture. The dwell time of each section has a process lower limit, and the total is the true bottom line of the cycle. The conveyor is taking away quickly, and the time for the workpiece to pass through the spray area is not enough. The surface of the washed thing looks clean, but there is still oil in the blind hole.

传送带速度要和前道工序“对表”。

The speed of the conveyor belt should be compared with the previous process.

通过式清洗机通常接在机加工线或焊接线后面。前道工序的节拍如果是两分钟一件，清洗机的传送带速度就按两分钟一件来设计。如果清洗机节拍比前道快，工件供不上，设备空转；比前道慢，前道工件堆积，整条线被清洗环节卡住。选型时要先算清楚前后道的节拍匹配，再倒推清洗机长度和传送速度。

The through type cleaning machine is usually connected behind the machining line or welding line. If the cycle time of the previous process is two minutes per piece, the conveyor speed of the cleaning machine should be designed according to two minutes per piece. If the cleaning machine beats faster than the previous one, the workpiece cannot be supplied, and the equipment runs idle; Slower than the previous one, the previous workpieces piled up, and the entire line got stuck in the cleaning process. When selecting, it is necessary to first calculate the matching rhythm of the front and rear channels, and then reverse the length and conveying speed of the cleaning machine.

喷嘴布局决定清洗有没有死角。

The nozzle layout determines whether there are any dead corners during cleaning.

通过式清洗机的喷淋方式通常分上下喷淋和侧喷淋。对于有深孔或盲孔的工件，上下喷淋只能清洗外表面，孔内靠重力自然进液效果有限。需要增加侧向或倾斜角度的喷嘴，对准孔口方向喷射。喷嘴的扇形角度、覆盖范围、距离工件的距离，都需要根据工件形状来设计。标准机型适合规则工件，异形件要做非标布局。

The spraying method of a through type cleaning machine is usually divided into upper and lower spraying and side spraying. For workpieces with deep or blind holes, up and down spraying can only clean the outer surface, and the effect of natural liquid injection into the hole by gravity is limited. Need to add nozzles with lateral or inclined angles and aim them towards the direction of the orifice for spraying. The fan-shaped angle, coverage range, and distance from the workpiece of the nozzle need to be designed according to the shape of the workpiece. Standard models are suitable for regular workpieces, while non-standard layouts are required for irregular parts.

漂洗级数是达标的关键，不是“冲一下就行”。

The level of rinsing is the key to meeting the standard, not just 'rinse once'.

精密件清洗后要求残留电导率低于某个限值，单级漂洗往往达不到。多级逆流漂洗是更可靠的做法：非常后一级用非常干净的水，逐级往前回流，水的利用率高，漂洗效果也稳定。选型时问清楚漂洗级数和是否需要纯水系统，这两项直接关系到清洗质量能不能稳定达标。

After cleaning precision parts, it is required that the residual conductivity be below a certain limit, which is often not achieved by single-stage rinsing. Multi stage countercurrent rinsing is a more reliable approach: the last stage uses the cleanest water and flows back step by step, with high water utilization and stable rinsing effect. When selecting, ask clearly about the rinsing level and whether a pure water system is needed, as these two directly affect whether the cleaning quality can be consistently met.

烘干段不是“吹吹就行”，要算热平衡。

The drying stage is not just about blowing, it needs to be considered as thermal balance.

烘干段的热风温度、风量、停留时间，需要根据工件的形状和重量来算。薄片状工件好烘干，实心块状工件内部蓄水，表面干了里面还有潮气。如果工件有盲孔，烘干时间要延长或者增加吹扫装置。烘干段短了，后道工序喷漆或装配会因为水汽出问题。

The temperature, air volume, and residence time of the hot air in the drying section need to be calculated based on the shape and weight of the workpiece. Thin sheet workpieces are easy to dry, while solid block workpieces have water stored inside, and there is still moisture inside when the surface is dry. If the workpiece has blind holes, the drying time should be extended or a blowing device should be added. The drying section is too short, and there may be issues with the subsequent painting or assembly processes due to water vapor.

通过式喷淋清洗机的选型逻辑很清晰：先按工件形状和清洁度要求算清洗工艺总时间，再按前后道节拍倒推传送速度，然后设计喷嘴布局和漂洗级数，非常后校验烘干段的热平衡。传送带跑多快是结果，工艺时间才是原因。

The selection logic of the through spray cleaning machine is very clear: first calculate the total cleaning process time according to the shape and cleanliness requirements of the workpiece, then reverse the conveying speed according to the rhythm of the front and rear passes, then design the nozzle layout and rinsing stage, and finally verify the thermal balance of the drying section. The speed of the conveyor belt is the result, and the process time is the reason.
