我矿自制的磨矿机自动记时装置,用于记录磨矿机的运转时间,其工作可靠,每台不超过30元。该装置由取压、整流、稳压和带日历晶体管钟等四部分组成。在磨矿机启动补偿器电磁线圈的外侧再缠一同心线圈,此线圈在磨矿机工作时感应出4～6伏交流电压,经二极管D_(1-4)桥式整流后送入
Mine mine self-made automatic timing device mill, used to record the running time of the mill, its reliable work, each not more than 30 yuan. The device consists of take pressure, rectifier, voltage regulator and calendar with four parts of the clock. At the outside of the magnet coil of the compensator for starting the mill, a concentric coil is wound around. The coil induces an alternating voltage of 4 to 6 volts during the operation of the grinding machine and is rectified by the diode D_ (1-4)
