The characteristic of high-pressure spray cleaning is to use a higher spray pressure than traditional ones, and use a dedicated nozzle to position and spray the workpiece at a fixed point; The spray pressure is 0.25MPA-0.5MPA, and the cleaning agent is a low foam, low concentration water-based cleaning solution.

发动机连杆高压喷淋清洗清洗工艺

High pressure spray cleaning process for engine connecting rods

发动机连杆高压喷淋清洗机采用传送链条步进输送。将连杆通过夹紧装置夹紧，步进下位送入密封高压清洗箱中，在该区采用上、下高压喷淋形成水流错位对喷，形成的漩涡流使连杆在密封清洗箱中可得到的清洗。清洗完成后，连杆上位进入局部清洗区，在局部清洗区喷嘴定位、定点对连杆细小孔进行高压冲洗。高压喷淋清洗机下部接有清洗剂回收箱，喷淋后的清洗剂通过清洗剂回收设备净化处理回收再次循环利用。清洗后的连杆步进送入真空烘干箱中，通过真空高温对连杆进行烘干，烘干后的连杆进入防锈区喷涂防锈液，经喷涂防锈液再输送到冷风冷却箱风干，然后步进下料位，卸下连杆，完成整个清洗过程。

The high-pressure spray cleaning machine for engine connecting rods adopts a conveyor chain for step-by-step transportation. Firstly, clamp the connecting rod through a clamping device and step it down into a sealed high-pressure cleaning box. In this area, the upper and lower high-pressure spraying are used to form a staggered flow of water, forming a vortex flow that allows the connecting rod to be thoroughly cleaned in the sealed cleaning box. After the cleaning is completed, the upper part of the connecting rod enters the local cleaning area, and the nozzle is positioned and fixed in the local cleaning area to perform high-pressure flushing on the small holes of the connecting rod. The lower part of the high-pressure spray cleaning machine is connected to a cleaning agent recycling box, and the sprayed cleaning agent is purified, recycled, and reused through the cleaning agent recycling equipment. The cleaned connecting rod is stepped into a vacuum drying box and dried through high vacuum temperature. The dried connecting rod enters the anti rust area and is sprayed with anti rust liquid. After spraying the anti rust liquid, it is transported to a cold air cooling box for air drying. Then, the connecting rod is stepped to the feeding position and removed to complete the entire cleaning process.

高压喷淋高压喷淋常用于零件表面形状较复杂且有螺纹孔、盲孔、窄缝隙及用其他清洗方法难于除去的硬质粘着微粒子的清洗，并根据被清洗零件表面的污物状态，选择合适的喷淋压力和清洗剂。

High pressure spraying is commonly used for cleaning hard adhesive particles with complex surface shapes, threaded holes, blind holes, narrow gaps, and other cleaning methods that are difficult to remove. Based on the dirt state on the surface of the cleaned parts, appropriate spraying pressure and cleaning agent are selected.

高压喷淋清洗机运行可靠，性能稳定。高压喷淋清洗技术的使用不仅提高了连杆的清洁度，同时间接地提高了连杆的使用寿命。使用碳氢清洗剂替代了传统的清洗剂，既提高了清洗效率又改善了清洗的工作环境。自动控制技术的应用降低了人工劳动成本，使设备的运行更可靠更，大幅度地提高了生产效率。

The high-pressure spray cleaning machine operates reliably and has stable performance. The use of high-pressure spray cleaning technology not only improves the cleanliness of the connecting rod, but also indirectly improves its service life. The use of hydrocarbon cleaning agents instead of traditional cleaning agents not only improves cleaning efficiency but also improves the working environment for cleaning. The application of automatic control technology has reduced labor costs, made equipment operation more reliable and safe, and greatly improved production efficiency.
