摘要
对前混合式磨料射流清洗油管进行了实验研究，研究结果表明，前混合式磨料射流清洗油管涂料的清洗速率随泵压和喷嘴直径的增大而增大，喷距、喷射角和颗粒直径的最佳值分别为１５０ｍｍ、１２０°（或６０°）和０．８ｍｍ。油管旋转速度与喷嘴平移速度的比值与清洗宽度成反比。前混合式磨料射流清洗油管涂料的速率大大高于后混合式磨料射流。
The experimental results on cleaning oil tube coating by premixed abrasive jet showed that the efficiency of the premixed abrasive jet for cleaning oil tube coating increased with pump pressure and diameter of nozzle. There exists a preferred value that results in the highest efficiency of the premixed abrasive jet for cleaning oil tube with the preferred standoff distance of 1 50 mm, jet angle of 120°or 60° and diameter of abrasive grain of 0. 8 mm. The ratio of rotary velocity of oil tube to shift velocity of nozzle is determined with cleaning width, and is inverse proportion to the cleaning width.Expcriment shows that the efficiency of premixed abrasive jet for cleaning oil tube coating is much better than that of postmixed abrasive jet.
