　　為了不讓泵水通過軸與密封間隙泄漏，由出口冷凝泵或在鹽水中的母管引至密封水。給水泵是一種具有一定溫度、高溫的水通過泵軸或泵體金屬容器用莒縣機械密封將熱(re)量傳給(gei)軸(zhou)(zhou)承，使軸(zhou)(zhou)承溫度升(sheng)高(gao)。為了控制(zhi)傳熱(re)，所以密封的水也起(qi)到冷卻(que)作用。

　　莒縣機械密封直接冷卻就是冷卻液體直接和密封端面接觸達到冷卻的目的。沖洗實際上也是直接冷卻的一種方式，沖洗方式中通過管路連接換熱器將冷卻后的沖洗液引入密封腔進行直接冷卻。還有一種直接冷卻就是在莒縣機械密封低壓側(大氣(qi))將清(qing)水(shui)、蒸(zheng)汽等(deng)冷卻流(liu)體直(zhi)接引入密(mi)封端(duan)泄露處(chu)的一(yi)種(zhong)冷卻方式，也(ye)稱急冷，急冷不(bu)僅(jin)冷卻*，還能(neng)將密(mi)封端(duan)面周圍(wei)的雜質及泄露液帶走，急冷液其壓力(li)(li)比(bi)密(mi)封介(jie)質壓力(li)(li)低。急冷液應盡量采(cai)用軟(ruan)水(shui)，以(yi)防(fang)(fang)止水(shui)垢產生破壞密(mi)封端(duan)面。當(dang)密(mi)封流(liu)體為易凝固、易結(jie)晶時(shi)，可(ke)用蒸(zheng)汽、溶劑等(deng)防(fang)(fang)止流(liu)體凝結(jie)。
