副立井提升由于提升量,提升对象,提升方式变化很大。要实现提升速度自动闭环控制比主井提升更为困难。近几年来我们采用了电动加速(提升对象自动记忆处理)—电动等速
Deputy shaft to enhance due to enhance the volume, enhance the object, upgrade methods vary greatly. It is more difficult to raise the speed of automatic closed-loop control than the main shaft hoisting. In recent years we used electric acceleration (to enhance the object automatic memory processing) - electric speed
