摘要
针对带式输送机传统传动方式普遍存在效率低、环节多、占用空间大、故障率高、安装工艺要求高、噪音大等问题,介绍了永磁同步电动滚筒在梁北选煤厂矸石带式输送机的应用实例,介绍了永磁直驱系统的工作原理,对比了设备改造前后传动结构、能耗、投资费用和使用效果。对比结果表明:永磁同步电机应用于带式输送机,传动系统结构简单、维护量少、运转平稳,噪音降低10dB,一年可节约用电约2万kW·h。
Aiming at the low efficiency, redundant links, large space occupation, high failure rate, high installation requirements and high noise of the traditional driving mode of the belt conveyor,we introduced the application of permanent magnet synchronous motorized pulley in the gangue belt conveyor in Liangbei Coal Preparation Plant,analyzed the permanent magnet direct drive system,compared the transmission structure,energy consumption,investment cost and effect of the machine before and after transformation. Application results show that, the drive system has simple structure, less maintenance and better operation,the noise is reduced by 10 decibel and 20 thousand kW·h of electricity is saved per year.
