                產品簡介

                產品介紹:

                GN型系列和3N6x2、4N5x2、4N6x2凝結水泵系臥式單吸多級懸臂式離心泵。3N6、4N6、6N6和NB型系列凝結水泵系單級懸臂式離心泵。GN型、N型、NB型凝結水泵比一般水泵有較好的汽蝕性能之特點。


                產品特點:

                 ·  泵的軸封采用填料密封或機械密封,并輔以外接水封水進行水封,以防進氣或漏水。

                 ·  在軸上的軸封處裝有可更換的軸套以保護泵軸,軸套與軸之間裝有O型密封圈,防止其配合間隙造成進氣或漏水。

                 ·  泵的傳動通過彈性聯軸器由電動機直接驅動。

                 ·  懸架部件采用兩個向心推力球軸承和一個單列向心球軸承的組合,支撐泵轉子部件并承受泵的徑向力和軸向力,軸承用潤滑油潤滑。


                產品用途:

                 ·  適用于冶金、發電廠、精煉廠、石油化工、低溫工程中,汽輪機冷凝水的抽送及高真空度要求密閉容器的液體抽送

                 ·  可用在介質與凝結水相似的其他地方

                 ·  輸送液體溫度在80℃以下(如裝上帶有冷卻結構的冷卻室,可輸送液體溫度150℃以下)
