环境污染水资源紧张农村打井取水情况较为普遍现有的三极管电路和浮球开关水位控制器故障率较高三极管电路构成的控制元件常出现的故障是抗干扰能力差会使三极管误动以浮球开关为形式的控制元件由于浮球的连接线经常会磨断以及开关触点的腐蚀和氧化故障率也较高且水井水量不足水泵长时间空抽容易毁坏电机。

本文比较成熟的电机抽水控制程序及说明，供您参考。-Environmental water stress is more common in rural water wells existing transistor level float switch controller circuit and a high failure rate of the control element transistor circuits often malfunction is anti-interference ability to make the floating transistor malfunction switch in the form of ball control elements as the float cable often wear off and the switch contact corrosion and oxidation failure rate is high and water wells pumping less likely to damage the pump motor air time this pumping more mature motor control program and instructions for your reference.
