富力煤矿折返二段钢带机电控及电气系统改造

Enriching the dint coal mine fold returns two steels takes the machine electricity controls and the electricity system reforms

由于采用可控硅整流控制,使机电系统运转平稳,速度调控方便。消除了原系统运煤启动时,速度变化大、加速度不平稳及启动时造成驱动轮轮衬与牵引钢丝绳间产生相对滑动,使轮衬及牵引钢丝绳磨损严重等缺点;而且取消了副电机和副减速机,减少了设备维修量。

Pass to take to the steel machine electric motor and eleetricities control the system to reform completely, making its attain to revolve steady, the speed adjusts to control the convenience and break down the low etc. in rate purpose, guaranteeing availably the lord carries the normal movement of the system.
