带式输送机组合式变频双电机驱动系统研究与应用
|
摘要
针对一些大型煤矿因采用大运量、长运距的双电机驱动带式输送机,而带来运输过程中的启停负荷、输送带张力、电机功率等变化幅度大等特点。采用PLC控制器对高压变频传动过程进行控制,以此保证煤矿带式输送机正常高效安全运行。通过对设计的带式输送机组合式变频双电机驱动系统进行测试,得到主电机和从电机具有基本相同的技术参数,对于实现矿井安全高效生产具有一定的现实意义。
Some large coal mines adopt double motor drive belt conveyor with large capacity and long haul distance,which brings the characteristics of large changes in starting and stopping load, belt tension, motor power and so on. PLC controller is used to control the process of high voltage frequency conversion drive,so as to ensure the normal,efficient and safe operation of coal mine belt conveyor. By testing the combined frequency conversion dual motor drive system of belt conveyor,it is found that the main motor and the slave motor have the same technical parameters,which has certain practical significance for realizing safe and efficient production in mine.
