自動(dòng)噴砂房的核心在于「程序控制」。其采用PLC（可編程邏輯控制器）或工業(yè)計(jì)算機(jī)系統(tǒng)，預(yù)設(shè)噴槍移動(dòng)軌跡、磨料流量、噴射壓力等參數(shù)。例如，通過機(jī)械臂或軌道式噴槍系統(tǒng)，可實(shí)現(xiàn)三維空間的精準(zhǔn)覆蓋，尤其適用于復(fù)雜曲面工件（如汽車輪轂、航空葉片）。自動(dòng)噴砂房，強(qiáng)調(diào)自動(dòng)化系統(tǒng)可集成除塵、磨料回收等功能，形成閉環(huán)處理。

　　The core of an automatic sandblasting room lies in 'program control'. It adopts PLC (Programmable Logic Controller) or industrial computer system to preset parameters such as spray gun movement trajectory, abrasive flow rate, and spray pressure. For example, precise coverage of three-dimensional space can be achieved through robotic arms or rail mounted spray gun systems, especially suitable for complex curved workpieces such as automotive wheels and aviation blades. Automatic sandblasting room emphasizes that the automation system can integrate functions such as dust removal and abrasive recovery, forming a closed-loop processing.

　　自動(dòng)噴砂房通常采用「壓送式」原理：磨料與壓縮空氣在混合室內(nèi)加壓后，通過管道輸送至噴槍，壓力穩(wěn)定且噴射力度強(qiáng)（參考B2B平臺(tái)數(shù)據(jù)，典型壓力范圍為0.6-0.8MPa）。部分高端機(jī)型還配備磨料自動(dòng)篩分裝置，可循環(huán)使用鋼丸、玻璃砂等材料。

　　Automatic sandblasting rooms usually use the principle of "pressure delivery": the abrasive and compressed air are pressurized in the mixing chamber and transported to the spray gun through pipelines, with stable pressure and strong spraying force (referring to B2B platform data, typical pressure range is 0.6-0.8MPa). Some high-end models are also equipped with automatic abrasive screening devices, which can recycle materials such as steel balls and glass sand.

　　手動(dòng)噴砂房多為「吸送式」設(shè)計(jì)，依靠文丘里效應(yīng)將磨料從儲(chǔ)料罐吸入噴槍。百度百家號(hào)某技術(shù)分析指出，這種方式壓力較低（約0.3-0.5MPa），適合鋁材、木材等軟質(zhì)基材，但磨料損耗率較高。

　　Manual sandblasting rooms are mostly designed as "suction type", relying on the Venturi effect to suck abrasives from the storage tank into the spray gun. According to a technical analysis on Baidu Baijiahao, this method has lower pressure (about 0.3-0.5MPa) and is suitable for soft substrates such as aluminum and wood, but has a higher abrasive loss rate.

　　自動(dòng)噴砂房的理論效率可達(dá)手動(dòng)操作的3-5倍。某船舶制造企業(yè)案例顯示，30平方米的鋼板表面處理，自動(dòng)系統(tǒng)僅需20分鐘，而手動(dòng)需2小時(shí)以上。這得益于多噴槍同步作業(yè)和連續(xù)進(jìn)料系統(tǒng)。

　　The theoretical efficiency of an automatic sandblasting room can reach 3-5 times that of manual operation. A case study of a shipbuilding enterprise shows that the automatic system only takes 20 minutes for surface treatment of a 30 square meter steel plate, while manual treatment takes more than 2 hours. This is due to the synchronous operation of multiple spray guns and continuous feeding system.

　　自動(dòng)化系統(tǒng)通過參數(shù)標(biāo)準(zhǔn)化實(shí)現(xiàn)Ra值（表面粗糙度）波動(dòng)范圍≤0.5μm，適合批量生產(chǎn)。某汽車零部件廠商的測(cè)試數(shù)據(jù)表明，自動(dòng)噴砂后涂層附著力測(cè)試合格率提升至99.3%。

　　The automation system achieves a fluctuation range of Ra value (surface roughness) ≤ 0.5 μ m through parameter standardization, which is suitable for mass production. The test data from a certain automotive parts manufacturer shows that the pass rate of coating adhesion testing after automatic sandblasting has increased to 99.3%.
