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.

發動機連桿高壓噴淋清洗清洗工藝

High pressure spray cleaning process for engine connecting rods

發動機連桿高壓噴淋清洗機采用傳送鏈條步進輸送。將連桿通過夾緊裝置夾緊，步進下位送入密封高壓清洗箱中，在該區采用上、下高壓噴淋形成水流錯位對噴，形成的漩渦流使連桿在密封清洗箱中可得到全方位的清洗。清洗完成后，連桿上位進入局部清洗區，在局部清洗區噴嘴定位、定點對連桿細小孔進行高壓沖洗。高壓噴淋清洗機下部接有清洗劑回收箱，噴淋后的清洗劑通過清洗劑回收設備凈化處理回收再次循環利用。清洗后的連桿步進送入真空烘干箱中，通過真空高溫對連桿進行烘干，烘干后的連桿進入防銹區噴涂防銹液，經噴涂防銹液再輸送到冷風冷卻箱風干，然后步進至下料位，卸下連桿，完成整個清洗過程。

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.

高壓噴淋高壓噴淋常用于零件表面形狀較復雜且有螺紋孔、盲孔、窄縫隙及用其他清洗方法難于除去的硬質粘著微粒子的清洗，并根據被清洗零件表面的污物狀態，選擇合適的噴淋壓力和清洗劑。

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.

高壓噴淋清洗機運行可靠，性能穩定。高壓噴淋清洗技術的使用不僅提高了連桿的清潔度，同時間接地提高了連桿的使用壽命。使用碳氫清洗劑替代了傳統的清洗劑，既提高了清洗效率又改善了清洗的工作環境。自動控制技術的應用降低了人工勞動成本，使設備的運行更可靠更安全，大幅度地提高了生產效率。

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.
