潜水电泵配套的磁力起动器跳闸时,应查明原因排除故障后再起动。可有的机手不管三七二十一,干脆用石头将“起动”按钮一压了事,强迫潜水电泵继续运行。这种做法很笨,是一种缺乏技术知识的表现。磁力起动器由交流接触器和热继电器两部分组成。当因电源电压过低、潜水电泵实际使用扬程太低(配离心泵)、抽泥浆等,磁力起动器均会跳闸,达到保护潜水电机的目的。在潜水电机过热或过载的情况下 Submersible pump supporting the magnetic starter tripping, you should find out the cause of the fault and then start. May have some hands Regardless of thirty-seven twenty-one, simply use the stone will “start ” button a pressure to force the submersible pump to continue running. This approach is stupid, is a lack of technical knowledge of the performance. Magnetic starter consists of AC contactor and thermal relay in two parts. When the power supply voltage is too low, the actual use of submersible pump is too low (with centrifugal pump), pumping mud, etc., the magnetic starter will trip to achieve the purpose of protecting the submersible motor. In case of submersible motor overload or overload
