根据西德引进PB泵消化的PB 4高层用砂浆输送、喷浆两用泵已由上海建筑施工技术研究所和华东建筑机械修造厂联合试制成功。经上海市建二公司装饰分公司在上海亚洲宾馆工程中考核试用,高度已超过原设计达到80米左右,其特点是:喷浆时无脉冲现象,无落地灰、喷浆均匀。作输送机用时送浆量也达到预期3—5立方米/小时要求。
The high-level mortar conveying and shotcreting pump for PB 4 which was digested by PB pump in West Germany has been successfully trial-produced by Shanghai Construction Technology Research Institute and Huadong Construction Machinery Repair Factory. Shanghai Shanghai Jian’er Decoration Co., Ltd. has applied for trials in the Asian Hotel Project in Shanghai, and its height has exceeded the original design by about 80 meters. Its characteristics are: no pulse phenomenon when spraying, no landing ash and even spraying. When used as a conveyor, the amount of slurry delivered is also expected to be 3-5 cubic meters per hour.
