我矿自制的设备运转记时装置可用于记录各种设备的运转时间,工作可靠,计时准确,价格低,每台不超过20元。该装置线路图如下图所示。设备起动时,XLC闭合,串接在计时线路中的辅助触点随之闭合,晶体管日历钟接通电源开始计时;停车时,电源切断,钟停。由于晶体管钟带有日历,每月只调整一次“零点”,月终得到设备的工作日数,算出设备的运转率。该装置装在选矿厂的7号磨机上,使用3个多月,证明计时准确可靠。
I mine self-made equipment operating chronograph device can be used to record a variety of equipment running time, reliable work, accurate timing, low prices, each not more than 20 yuan. The device circuit diagram as shown below. When the device is started, XLC is closed, the auxiliary contact cascaded in the timing circuit is closed, the transistor calendar clock is connected to the power and starts counting; when the vehicle is stopped, the power is cut off and the clock is stopped. As the transistor clock with a calendar, adjust only once a month “zero”, the end of the month to get the number of equipment, calculate the operation rate of equipment. The device installed in the dressing mill No. 7 mill, the use of more than 3 months, that timing accurate and reliable.
