很多厂长觉得，只要工件能“走”过一条喷淋线，就算自动化了。真正投产才发现：外面洗干净了，螺纹孔里还塞着铁屑；烘干出来看着干，装配前一摸全是水膜。问题不在机器贵不贵，在工艺段有没有配齐。

Many factory managers believe that as long as the workpiece can pass through a spray line, it is considered automated. Only when it was truly put into production did I realize that the outside had been washed clean, but there were still iron filings stuffed into the threaded holes; After drying, it looks dry, but before assembly, it feels like a water film. The problem is not whether the machine is expensive or not, but whether it is fully equipped in the process section.

通过式喷淋清洗机的本质，是网带送料 + 多段处理：上料→高压喷淋粗洗→沥水→漂洗→风刀切水→热风烘干→下料。它擅长啃大平面、重油污、大批量机加件（壳体、齿轮、轴承、汽配冲压件），节拍快、人工少。

The essence of the through type spray cleaning machine is mesh belt feeding+multi-stage processing: feeding → high-pressure spray coarse washing → draining → rinsing → air knife cutting water → hot air drying → discharging. It is good at gnawing on large flat surfaces, heavy oil stains, and large quantities of machined parts (shells, gears, bearings, automotive stamping parts), with fast pace and less labor.

选型盯住5个数，比听销售讲故事有用：

Focusing on 5 numbers for selection is more useful than listening to salespeople tell stories:

网带宽度与高度：按非常大工件外廓留10–20mm余量，别卡着出色做；

Mesh belt width and height: Leave a margin of 10-20mm according to the maximum workpiece outline, and do not limit it;

喷淋压力：普通除油0.3–0.6MPa，带切削液硬垢可到1.0–1.5MPa，但薄壁件压力过高会变形；

Spray pressure: 0.3-0.6MPa for ordinary oil removal, 1.0-1.5MPa for hard scale with cutting fluid, but excessive pressure on thin-walled parts can cause deformation;

过滤精度：铁屑多的工况配磁性分离+袋式过滤，精度50–100μm，不然喷嘴三天一堵；

Filtering accuracy: For working conditions with a high amount of iron filings, magnetic separation and bag filtration are used, with an accuracy of 50-100 μ m, otherwise the nozzle will clog every three days;

烘干温度：60–120℃分区控温，先风刀再热风，否则盲孔必留水印；

Drying temperature: 60-120 ℃ temperature control zone, with air knife first and then hot air, otherwise blind holes will leave watermarks;

输送速度：0.15–1.5m/min变频可调，和前后机床节拍对齐，别为了“看起来快”把速度拉满。

Conveyor speed: 0.15-1.5m/min, adjustable by frequency conversion, aligned with the rhythm of the front and rear machine tools, do not pull the speed to the limit just to make it look fast.

两个容易踩的坑：

Two easy pitfalls to tread on:

深孔、盲孔件别只用喷淋——外层干净、孔内藏污，正确做法是“喷淋预洗+超声波精洗”组合线；

Do not only use spraying for deep and blind hole parts - the outer layer should be clean and the hole should be dirty. The correct method is to use a combination line of "spray pre washing+ultrasonic fine washing";

铝件和钢件别共用同一套碱液配方，铝件要用中性/弱碱清洗剂，否则发白腐蚀。

Aluminum and steel parts should share the same alkaline solution formula. Aluminum parts should be cleaned with neutral/weak alkaline cleaning agents, otherwise they will turn white and corrode.

签合同前让厂家拿你的工件做免费试洗，看洁净度、看烘干后有无水渍、看连续跑2小时压降变化。能试样、敢写质保响应时间的，才值得下单。

Before signing the contract, ask the manufacturer to take your workpiece for a free trial wash to check the cleanliness, whether there are any water stains after drying, and the pressure drop change after running continuously for 2 hours. Only those who can sample and dare to write the warranty response time are worth placing an order.
