二、產(chǎn)品概述
 
    DQLB型便拆立式管道離心泵是在ISG型泵的基礎(chǔ)上開發(fā)成功的一種結(jié)構(gòu)新穎,技術(shù)*的產(chǎn)品。
   
    該立式泵告別是在整體結(jié)構(gòu)上進(jìn)行大膽突破設(shè)計。采用獨(dú)立軸承體、泵軸支撐,解決了原來立式泵靠電機(jī)軸承支撐的不足之處;采用優(yōu)秀水力模型的葉輪,消除了原立式泵軸向力大的不足之處;電機(jī)采用Y系列標(biāo)準(zhǔn)通用電機(jī),解決原立式泵加長軸電機(jī)配套更換難的問題;同時99%的便拆結(jié)構(gòu),解決了更換大功率水泵的軸承、機(jī)械密封、葉輪、泵軸的難題。
   
    該泵與國內(nèi)同類產(chǎn)品相比,具有運(yùn)轉(zhuǎn)更平穩(wěn)、使用壽命長、配套更方便、維護(hù)保養(yǎng)更輕松等等,的優(yōu)點(diǎn)。在立式泵系列產(chǎn)品中屬國內(nèi)前列,各項(xiàng)技術(shù)居國內(nèi),是替代ISG型立式泵、IS型離心泵、S型雙吸泵等常規(guī)各種離心泵的產(chǎn)品。
 
三、工作條件
 
1、泵系統(tǒng)工作壓力為1.6MPa,即泵吸入口壓力+泵揚(yáng)程≤1.6MPA(泵揚(yáng)程工作壓力大于1.6MPa時應(yīng)在訂貨另行提出,以便在制造時泵的過流部件和聯(lián)接部件采用鑄鋼)。
2、輸送介質(zhì)為清水或物理化學(xué)性質(zhì)類似清水的其它液體。(輸送介質(zhì)帶有細(xì)小顆粒的應(yīng)在訂貨時另行說明,以便裝配耐磨式機(jī)械密封)。
3、環(huán)境溫度≤40℃,海拔高度≤1000m,相對濕度≤95%
