铜山矿业公司金属矿山主井承担着矿/废石及部分检修材料的提升运输任务,主井提升机能否安全、高效、可靠运行,对矿山生产与安全关系重大。1系统配置该主井提升机1991年初建成投产,设计生产能力为120万t/a。系统由北京有色设计院设计,机械部分由中信重工机械股份有限公司生产。主电动机是上海电机厂生产的低速直联电动机,电控系统全套从ABB公司引进,是国内较早引进全数字直流拖动提升机。提升机为JKMD-4×4型多绳摩擦落地式。由
The main shaft of the metal mine in Tongshan Mining Company shoulders the task of upgrading and transporting the ore / waste rock and some maintenance materials. Whether the main shaft hoist can be operated safely, efficiently and reliably is of great importance to mine production and safety. 1 System Configuration The main shaft hoist put into operation in early 1991, design production capacity of 1.2 million t / a. The system is designed by Beijing Nonferrous Design Institute and the mechanical part is produced by CITIC Heavy Industry Machinery Co., Ltd. The main motor is a low-speed direct-coupled motor produced by Shanghai Electric Machinery Factory. The complete electronic control system was introduced from ABB Company. It is the earlier introduction of all-digital DC drag hoist in China. Hoist for the JKMD-4 × 4 type multi-rope friction floor. by
