旧砂气力吸送在上海拖拉机厂已使用14年之久,其最大输送量曾达27吨/时,经吸送后的旧砂含泥量为8～11％,新砂消耗只占型砂日耗量1～2％,陶土与煤粉消耗小于1％。本文介绍他们加强维护管理、不断改进,保证稳定生产的经验。并对旧砂气力吸送的经济效果进行了分析,认为:旧砂吸送量在1.5吨/时以下、输送管路在30米以内更为适用。
Old sand pneumatic suction in Shanghai tractor factory has been used for 14 years, the maximum delivery volume has reached 27 tons / hour, the amount of sand after the suction of 8 to 11%, the new sand consumption only accounted for sand consumption 1 ~ 2%, clay and coal consumption less than 1%. This article describes their experience in strengthening maintenance management, continuous improvement, and ensuring stable production. And the economic effect of the old sand pneumatic suction was analyzed, that: the amount of the old sand suction at 1.5 tons / h below, the transmission line is more applicable within 30 meters.
