高压水喷砂是近年发展起来的一种新的清洗技术,由于它具有清洗效率高、质量好、动力消耗少和无粉尘污染等优点,受到使用单位的欢迎。由冶金部长沙矿冶研究院研制的GSPS—80型高压水喷砂机,用于清洗金属表面氧化皮、焊渣和锈蚀效果好,速度快。 1.工作原理借助于10～12MPa的高压水的高速喷射,使喷嘴周围形成负压将砂浆吸出,吸出的砂浆与高速喷射的高压水混合并加速,产生巨大的能量撞击金属表面的氧化物,由于物理的破碎
High pressure water sand blasting is a new cleaning technology developed in recent years. It is welcomed by the users due to its advantages of high cleaning efficiency, good quality, less power consumption and no dust pollution. GSPS-80 high-pressure water blasting machine developed by the Ministry of Metallurgy, Mining and Metallurgy Research Institute of Metallurgical Department is used for cleaning the surface of the metal oxide scale. The welding slag and corrosion effect are good and the speed is fast. 1. Working principle With the help of 10 ~ 12MPa high-pressure water jet, the negative pressure around the nozzle will suck the mortar, sucked out of mortar and high-speed jet of high-pressure water mixing and acceleration, resulting in huge energy impact on the metal surface oxide, Due to the physical fragmentation
