由张家口煤矿机械厂研制的新一代SGZ-764/400型刮板输送机经过几年的研制和攻关,最近在张家口问世,并通过出厂评议。该机综合了国内外各种输送机的优点,选用了多种新结构,采用了新技术、新工艺,并提出了过煤量200万吨,中部槽联接强度200吨的较高技术指标,是目前较先进的刮板输送设备。这种刮板输送机采用了双速电机和双速真空磁力起动器,改善了输送机的启动性能;减少了易发事故的环节;中部槽采用了封底形式,选用了25mm厚中板和精铸高锰钢端
Developed by Zhangjiakou Coal Mine Machinery Factory, a new generation of SGZ-764/400 scraper conveyor after several years of research and research, recently came out in Zhangjiakou, and passed the factory review. The machine combines the advantages of various domestic and foreign conveyor, selected a variety of new structures, the use of new technologies and new processes, and put forward the amount of 200 tons of coal, the central tank joint strength of 200 tons of high-tech indicators, Is the more advanced scraper conveyor equipment. This scraper conveyor uses a two-speed motor and two-speed vacuum magnetic starter to improve the conveyor’s start-up performance; reduce the accident prone part of the central groove using the back cover, the choice of 25mm thick plate and fine Cast high manganese steel end
