水环真空泵在使用过程中常常会出现结构的问题,导致泵内的热传递环境逐渐被破坏,热交换频率越来越低,进而使泵的运转收到影响,降低了它的工作效率,那么,水环真空泵中的水垢是如何形成的呢?我们来看一下下面的内容吧!

1、受热分解

含有硬度成分的循环水进入水环真空泵后,随泵的旋转在泵体内形成水环做功发热,使溶解在水中的重碳酸盐逐渐分解,并沉淀析出,结成水垢。

2、溶解度降低

负溶解度温度系数的盐类随着循环水水温的升高而降低溶解度,并析出沉淀形成结垢。

3、相互反应

循环水中原本溶解度较大的盐类在真空泵的运行过程中和其他盐类发生物理化合反应,形成难溶物质而形成水垢。

4、蒸发和浓缩

循环水不断做功发热,不可避免地要产生蒸发和浓缩,使水中溶解盐的浓度不断增大,达到饱和时析出沉淀,形成水垢。

运行中的水环真空泵产生的水垢有盐垢和污垢2种,它们的成分因水源不同而各不相同,我们应详细分析水垢的形成原因及其成分,这样才能采取有效措施加以解决。
