在供水工程中,用水泵向水塔盛水桶內送水时,一般是设专人来掌握桶內裝水情况,以防止盛水过多,溢出桶外.这样既不方便,也浪费人力.最近一○五勘探队在向水塔送水的工作中,利用了指示灯来控制水塔的裝水情况,这项方法是李树棠同志提出的.装设与使用非常简单,其电路装设如图所示.从电源引用一根单线,通过招示灯,引入水塔上的盛水桶內,联结在铁块上.铁块固定在所需装水的位置上.铁块裝在桶壁上,必需良好的绝缘(铁质或导电物质制成的盛水桶),导线进入桶內亦应与捅保持绝缘.工作中,当水桶內水位上升,遇到铁块时,则使整个电路构成一个完整的通路,指示灯即明
In the water supply project, when water is pumped into the water tower tub, it is usually set up for people to grasp the water content in the barrel to prevent excessive water overflow and overflow the barrel. This is inconvenient and wastes manpower. During the work of supplying water to the water tower, the five exploration teams used indicator lights to control the water content of the water tower. This method was proposed by Comrade Li Shuzheng. The installation and use were very simple. The circuit installation was as shown in the figure. Reference a single line, through the instruction lamp, into the water tank on the water tower, connected to the iron block. Iron block fixed in the required water position. Iron block installed in the barrel wall, the need for good insulation (iron Or the bucket made of conductive material, the wire into the barrel should also be kept insulated from the crucible. During work, when the water level in the bucket rises and meets the iron block, the whole circuit constitutes a complete access, the indicator light is clear
