简单可靠的水位控制器李荐（西北矿冶研究院，甘肃白银市，７３０９００）我单位有一台１１ｋｗ的水环式真空泵，用水量较大，需解决水的循环利用问题。为此笔者设计制作了一台水位控制器，将水由低位槽泵人高位槽，然后再经水环真空系流回低位槽。经使用表明，该电路工作...
Simple and Reliable Water Level Controller LI Jian (Northwest Mining and Metallurgy Research Institute, Baiyin, Gansu, 730900) My unit has a 11kw water ring vacuum pump with large water consumption, which needs to solve the problem of water recycling. For this reason, I designed and manufactured a water level controller, which pumps the water from the low level tank to the high level tank and then flows back to the low level tank via the water ring vacuum system. After use indicates that the circuit is working ...
