　　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南口街道機械密封將熱量傳(chuan)給軸(zhou)(zhou)承(cheng)，使軸(zhou)(zhou)承(cheng)溫度(du)升高。為了控(kong)制傳(chuan)熱，所以(yi)密封的(de)水也起到(dao)冷卻作(zuo)用。

　　南口街道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南口街道機械密封低壓側(大(da)氣)將(jiang)清水(shui)、蒸汽等冷(leng)卻(que)流(liu)體(ti)直接(jie)引入密封(feng)端(duan)(duan)泄(xie)(xie)露處的(de)一種冷(leng)卻(que)方式，也稱急冷(leng)，急冷(leng)不(bu)僅冷(leng)卻(que)*，還能將(jiang)密封(feng)端(duan)(duan)面周圍的(de)雜質(zhi)及泄(xie)(xie)露液帶走，急冷(leng)液其壓力比密封(feng)介質(zhi)壓力低。急冷(leng)液應(ying)盡量采用軟(ruan)水(shui)，以防止(zhi)水(shui)垢產(chan)生破壞密封(feng)端(duan)(duan)面。當密封(feng)流(liu)體(ti)為易凝固、易結(jie)晶(jing)時，可用蒸汽、溶劑等防止(zhi)流(liu)體(ti)凝結(jie)。
