　　In the field of high-end equipment manufacturing, the removal of burrs and residues in the inner cavity and intersecting pores of heavy-duty castings has always been a challenge due to their complex structure and large size. The dedicated high-pressure deburring cleaning machine achieves efficient removal of micro scale residues in castings through innovative fluid dynamics design and intelligent control, significantly improving product qualification rate and production cycle.

　　高壓水射流技術(shù)突破

　　Breakthrough in High Pressure Water Jet Technology

　　設(shè)備核心采用超高壓往復(fù)式增壓系統(tǒng)，可將自來水加壓至300-500MPa，形成直徑0.1-0.3mm的聚焦水射流。該射流在特定噴嘴作用下產(chǎn)生空化效應(yīng)，水滴以超音速沖擊鑄件表面，對硬度達(dá)HRC50的殘?jiān)鼘?shí)現(xiàn)剪切剝離。某航空發(fā)動機(jī)機(jī)匣清洗實(shí)驗(yàn)顯示，單次作業(yè)殘?jiān)コ蔬_(dá)98.6%，較傳統(tǒng)工藝提升3倍效率。

　　The core of the equipment adopts an ultra-high pressure reciprocating pressurization system, which can pressurize tap water to 300-500MPa, forming a focused water jet with a diameter of 0.1-0.3mm. The jet produces cavitation effect under the action of a specific nozzle, and water droplets impact the surface of the casting at supersonic speed, achieving shear peeling of residue with a hardness of HRC50. The cleaning experiment of a certain aircraft engine casing showed that the removal rate of single operation residue reached 98.6%, which is three times more efficient than traditional processes.

　　多軸聯(lián)動精準(zhǔn)操控

　　Multi axis linkage precise control

　　針對復(fù)雜型腔結(jié)構(gòu)，設(shè)備配置六軸聯(lián)動機(jī)械臂，結(jié)合激光掃描建模技術(shù)，可自動生成最優(yōu)清洗路徑。機(jī)械臂重復(fù)定位精度達(dá)±0.05mm，確保水射流精準(zhǔn)穿透直徑3mm的深孔。在某重型燃?xì)廨啓C(jī)葉片清洗中，該系統(tǒng)成功清除隱藏在1.2米深流道內(nèi)的氧化皮，較人工清理時間縮短85%。

　　For complex cavity structures, the equipment is equipped with a six axis linkage robotic arm, combined with laser scanning modeling technology, which can automatically generate the optimal cleaning path. The repeated positioning accuracy of the robotic arm reaches ± 0.05mm, ensuring that the water jet accurately penetrates deep holes with a diameter of 3mm. In the cleaning of a heavy-duty gas turbine blade, the system successfully removed the oxide scale hidden in the 1.2-meter deep flow channel, reducing the cleaning time by 85% compared to manual cleaning.

　　旋流分離與循環(huán)過濾

　　Cyclone separation and circulating filtration

　　為解決殘?jiān)厥针y題，設(shè)備集成三級旋流分離裝置。含渣水流經(jīng)一級切向入口產(chǎn)生螺旋運(yùn)動，在離心力作用下，粒徑大于50μm的顆粒被甩至錐壁并沉淀。二級聚結(jié)濾芯采用梯度孔徑設(shè)計(jì)，逐級攔截微米級殘?jiān)Ｈ壏礉B透膜過濾系統(tǒng)則確保循環(huán)水清潔度達(dá)NAS 6級，實(shí)現(xiàn)95%以上的水資源循環(huán)利用。

　　To solve the problem of residue recycling, the equipment integrates a three-stage cyclone separation device. The slag containing water flows through the first tangential inlet to generate spiral motion. Under the action of centrifugal force, particles with a diameter greater than 50 μ m are thrown to the cone wall and precipitate. The secondary coalescing filter adopts a gradient pore size design to intercept micron sized residues step by step. The three-stage reverse osmosis membrane filtration system ensures that the cleanliness of the circulating water reaches NAS level 6, achieving over 95% of water resource recycling.

　　清洗過程搭載聲發(fā)射檢測模塊，通過分析殘?jiān)鼊冸x產(chǎn)生的聲波信號，實(shí)時判斷清洗終點(diǎn)。當(dāng)特征頻段信號幅值衰減至閾值時，系統(tǒng)自動切換至柔性沖洗模式，避免過洗損傷基體。某汽車變速箱殼體生產(chǎn)線數(shù)據(jù)顯示，該閉環(huán)控制使單件清洗能耗降低40%，同時將表面粗糙度控制在Ra1.6μm以內(nèi)。

　　The cleaning process is equipped with an acoustic emission detection module, which analyzes the sound wave signals generated by residue peeling to determine the cleaning endpoint in real time. When the amplitude of the characteristic frequency band signal decays to the threshold, the system automatically switches to flexible flushing mode to avoid damage to the substrate caused by over washing. According to data from a production line for a certain automobile gearbox housing, this closed-loop control reduces energy consumption for single cleaning by 40%, while controlling surface roughness within Ra1.6 μ m.

　　The equipment adopts a fully enclosed explosion-proof structure, and the pressure resistance level of the cleaning compartment reaches 1MPa. It is equipped with combustible gas concentration monitoring and automatic pressure relief devices. The wastewater treatment system uses Fenton oxidation and activated carbon adsorption to achieve a chemical oxygen demand (COD) discharge concentration below 50mg/L, meeting the national first-class discharge standard. In a wind power bearing manufacturing enterprise, the annual hazardous waste generation was reduced by 200 tons, resulting in significant environmental benefits.
