一、DL立式多級(jí)離心泵產(chǎn)品概述：
DL立式多級(jí)離心泵是采用國(guó)家推薦使用的高效節(jié)能產(chǎn)品IS型泵的水力模型，為立式多級(jí)多節(jié)段式結(jié)構(gòu)。螺桿把進(jìn)水段、中段、出水段夾緊聯(lián)成一體。水泵每一級(jí)裝一個(gè)葉輪、一個(gè)導(dǎo)水葉。軸向力采用水力平衡法解決，殘余軸向力由球軸軸承承受，用油脂潤(rùn)滑。軸封采用軟填料或機(jī)械密封。產(chǎn)品執(zhí)行JB/T2727-93《立式多級(jí)離心泵型式與基本參數(shù)》標(biāo)準(zhǔn)，主要供吸送稀釋的、清潔的、不腐蝕的、不爆炸的清水及物理化學(xué)性質(zhì)類似水的不含固體顆粒或纖維的液體，具有效率高、性能范圍廣、運(yùn)轉(zhuǎn)安全、平穩(wěn)、壽命長(zhǎng)、占地面積小，安裝維修方便等特點(diǎn)。
廣泛應(yīng)用于高層建筑的消防、生活供水以及空調(diào)機(jī)組循環(huán)、冷卻水輸送。
