概述
DLY立式液下多級泵是一種特殊型式的多級離心泵。廣泛適用于采油廠、化工廠、煉油廠、發(fā)電廠、水廠等輸送各種物理或化學(xué)性能類似于清水的油類及油水混合物。
性能范圍
流量:Q 6-400m3/h
揚程:H 15~600m
溫度:T -40℃~+180℃
粘度:δ ≤200cst(厘沲)
特殊工況,另可設(shè)計
結(jié)構(gòu)特點
該系列泵為節(jié)段剖分立式多級離心泵,電機采用立式防爆型,從電機端看為逆時針旋轉(zhuǎn)。介質(zhì)從底部軸向吸入,水平吐出。安裝便利,極為適合戶外安裝作業(yè)
軸向力主要由平衡鼓承受,并設(shè)置推力球軸承平衡殘余軸向力。軸封采用迷宮式節(jié)流減壓,加填料密封,保證填封處無泄漏。微少的液體從溢流管排回吸液池。
