1皮带及斗式提升机的打滑信号为了更好地检测皮带及斗式提升机(以下简称为“设备”)的工作状态,避免“设备”出现打滑(包括皮带打滑、联轴器尼龙棒断裂和液力偶合器喷油等)时对“设备”本身及后续设备带来的危害,“设备”尾部都装有打滑检测装置。建厂伊始,“设备”自带的是普通的接近开关,发出的是脉冲信号,导致DCS的隔离继电器频繁动作,降低了继电器的使用寿命,且DI点是以
1 Belt and bucket elevator slip signal In order to better detect the belt and bucket elevator (hereinafter referred to as “equipment ”) working condition, to avoid “equipment ” slipping (including belt slip, coupling Nylon rod breakage and hydraulic coupling fuel injection, etc.) on the “equipment ” itself and the follow-up equipment hazards, “equipment ” tail are equipped with skid detection device. The beginning of construction, “equipment ” comes with a common proximity switch, the issue of a pulse signal, resulting in frequent DCS isolation relay action, reducing the life of the relay, and the DI point is
