我局王庄矿使用的100千瓦离心式扇风机,过去启动与停止运行都是就地操作;监护风机运行状态是由值班人员就地检查看护。同时,风机房噪音很大,影响职工身体健康。矿三结合技术革新小组,发扬自力更生的革命精神,自行设计,自己动手,组装了两套遥控设备,实现了矿井主扇风机运行自动化。每天可减少值班人员三人,通过三年来的运行实践证明,元件灵敏可靠,运行性能良好。一、主控回路(见图1)1、扇风机启动:按下启动按钮1K_1,启动接触器线卷(?)_1经(?)_2、2P(?)常闭接点通
Wangzhuang mine Bureau of 100 kilowatts centrifugal fans used to start and stop the operation of the past are the local operation; monitoring fan running status is on duty by local duty inspection and care. At the same time, the fan room noise is large, affecting the health of workers. Mine three combination of technical innovation group, carry forward the revolutionary spirit of self-reliance, self-designed, do it yourself, the assembly of two sets of remote control equipment, to achieve mine main fans running automation. Reduce the number of people on duty every day, through three years of operation proved that the components are sensitive and reliable, good running performance. First, the main control circuit (see Figure 1) 1 fan fan start: Press the start button 1K_1, start the contactor coil (?) _ 1 by (?) _ 2,2P
