一、概况我厂水源井较多且分散。每井设专人看管,按水位高低来开停水泵,既费事又不及时。厂三结合射流小组经十几天的研究试验,实现了用射流技术控制水井水位,能按规定的高低水位自动开停水泵。经实际使用,效果良好。二、动作原理控制线路如图。采用两个或非元件:一个控制高水位,另一个控制低水位。设置一个高水位水槽,作为向元件供水的稳压水源。当水位上升堵住水位管口时,或非元件(一)由原来的右边流水变换到左边流水,水电转换器动作,接通了磁力开关的常闭接点。水
I. Overview Our plant water wells are more dispersed. Every well is set up to be supervised and the water pump is opened and stopped according to the water level, which is both costly and not timely. After three days of research and trials, the three-jet team of the company realized the use of jet technology to control the water level of wells, and can automatically start and stop the pump at the prescribed high and low water levels. The actual use, the effect is good. Second, the principle of action control circuit as shown. Two or more elements are used: one to control the high water level and the other to control the low water level. Set a high-level water tank as a constant-pressure source of water for the component. When the water level rises and the water level nozzle is blocked, or the non-element (1) changes from the original right water flow to the left flow, the water and electricity converters act to close the normally closed contact of the magnetic switch. water
