工作原理： 全自动钠离子交换器采用离子交换原理，去除水中的钙、镁等结垢离子。当含有硬度离子的原水通过交换器内树脂层时，水中的钙、镁离子便与树脂吸附的 钠离子发生置换，树脂吸附了钙、镁离子而 钠离子进入水中，这样从交换器内流出的水就是去掉了硬度的 软化水。
Working principle: the fully automatic sodium ion exchanger adopts the principle of ion exchange to remove calcium, magnesium and other scaling ions in water. When the raw water containing hardness ions passes through the resin layer in the exchanger, the calcium and magnesium ions in the water will be replaced with the sodium ions adsorbed by the resin. The resin adsorbs the calcium and magnesium ions and the sodium ions enter the water, so the water flowing out of the exchanger is the softened water with the hardness removed.
