提升机自动控制与变频节能改造实践

Renovation practice of automatic control and frequency conversion of mine hoist for energy saving

矿井提升系统是地下开采矿山主要的生产系统之一,提升机的自动控制与变频节能对矿山的降本增效至关重要。针对鑫泰矿业公司老式提升机主要依靠电动机转子串电阻调速控制存在的控制精度低、安全性差等问题,介绍了PLC及变频器控制提升系统,详述了PLC及变频器控制提升系统的构成、特点以及自动准确平滑启停的实现方法。应用实践表明,PLC及变频器控制提升系统控制性能优良、操作简便、运行效率高、节能效果显著。

Mine hoisting system is one of the most important production systems in underground mining,and the automatic control and frequency conversion for energy saving of hoists are vital for achieving cost effective results.Considering the lowing control precision and safety deficiency existing in the old-fashioned hoists of Xintai mining company,the paper proposes PLC and frequency conversion hoisting system and introduces in detail the construction,features and the implementation method of accurate and smooth automatic control of on and off of the system.Application practice proves the PLC and frequency conversion hoisting system to be effective,easily accessible,efficient and energy-saving.
