易门铜矿三家厂分矿的4号箕斗井以及罐笼付井,过去均用机械行程开关作过卷扬开关,因常被撞坏而造成过卷扬保护失灵。针对这一问题,经研究改用光电控制器代替了原用的机械行程开关。其动作原理是:当光源被提升容器遮断时,RS—CW系列光电管联结的JGK—Ⅱ型光电控制器立即动作,切断卷扬机的保险器,从而达到控制过卷的目的,如附图所示。
Yimen Copper Mine three sub-ore plant on the 4th bucket and cage to pay wells, the past are used mechanical trip switch made hoist switch, often damaged crashed caused hoisting failure. In response to this problem, the study replaced the photoelectric controller to replace the original mechanical travel switch. The action principle is: When the light source is lifted container to be interrupted, RS-CW series photocell connected JGK-Ⅱ photoelectric controller immediately action, cut off the winch fuse, so as to achieve the purpose of controlling the volume, as shown in the figure .
