农村的水箱和水塔上水一般是手动,使用起来很不方便,有时一不注意就会造成跑水。笔者用手头有的零件自制了一个自动水位控制器,如图所示。原料按图所标,无需调整就能正常使用。三相电机、单相电机都可以控制。 工作原理很简单。A、B、C三个触点,放在水箱或水塔的适当位置(如图),当水塔无水时,A、B、C三点不能接通,T_1没 Water tank and water tower in rural areas are generally manual, very inconvenient to use, and sometimes do not pay attention to will cause running water. The author made an automatic water level controller with some parts on hand as shown in the figure. Raw materials according to the picture, without adjustment can be used normally. Three-phase motors, single-phase motors can be controlled. The working principle is very simple. A, B, C three contacts, on the tank or tower in the appropriate location (Figure), when the water tower is dry, A, B, C three can not be connected, T_1 did not
