DA1型多級離心泵是單吸、多級、分段式離心泵,用于汲送清水及無腐蝕性的液體,改變過流零件的材料,可供礦山排送酸性水。介質(zhì)最高溫度80℃。流量范圍3-350m3/h,揚(yáng)程范圍13-400m。
DA1系列是本廠自行設(shè)計(jì)的產(chǎn)品,因其體積小、效率高等特點(diǎn),一直是工業(yè)、農(nóng)業(yè)、交通、民用等部門受歡迎產(chǎn)品。曾獲部優(yōu)產(chǎn)品稱號。
泵的軸封為填料密封、機(jī)械密封。主要零件的制造材料為:進(jìn)水段、中段、出水段等承壓零件——普通鑄鐵、球墨鑄鐵或不銹鋼;葉輪——鑄鐵、鑄鋼或不銹鋼;軸——碳鋼或不銹鋼。
多級泵主要由定子、轉(zhuǎn)子、軸承和軸封四大部分組成:
1、多級泵定子部分主要由吸入段、中段、吐出段和導(dǎo)葉等組成,有拉緊螺栓將各段夾緊,構(gòu)成工作室。 D型多級泵泵一般水平吸入,垂直向上吐出;用于是油田注水時,泵進(jìn)出口均垂直向上。 DG型多級泵出、入口均垂直向上。
2、多級泵轉(zhuǎn)子部分主要由軸、葉輪、平衡盤和軸套等組成。軸向力由平衡盤平衡。
3、多級泵軸承主要由軸承體、軸承和軸承壓蓋等組成,軸承用油脂或稀油潤滑。
4、多級泵軸封采用軟填料密封,主要由進(jìn)水段和尾蓋上的密封函體、填料、擋水圈等組成。 D型多級泵泵水封水來源于泵內(nèi)的壓力水。 DG型多級泵泵水封水來源于外部供水。
5、多級泵轉(zhuǎn)動泵通過彈性聯(lián)軸器由原動機(jī)直接驅(qū)動。從原動機(jī)端看泵,泵為順時針方向旋轉(zhuǎn) D、 DG型多級泵泵是臥式單吸多級節(jié)段式離心泵。供輸送清水(含雜質(zhì)量小于1%,顆粒度小于0.1mm)或物理化學(xué)性質(zhì)類似于水的其它液體。 D型多級泵泵輸送介質(zhì)溫度小于80℃,適用于礦山排水、油田注水、工廠和城市給、排水等場合。油田注水泵根據(jù)介質(zhì)的腐蝕性,泵采用不同的材質(zhì)。 DG型泵輸送介質(zhì)溫度小于105℃,適用于各種鍋爐給水。
設(shè)計(jì)院在設(shè)計(jì)裝置設(shè)備時,要確定多級泵的用途和性能參數(shù)并選擇泵型。這種選擇首先得從選擇泵的種類和形式開始,以什么原則來選擇多級泵,選擇的依據(jù)又是什么呢?
1、使所選多級泵的型式和性能符合裝置流量、揚(yáng)程、壓力、溫度、汽蝕余量、吸程等工藝參數(shù)的要求。
2、多級泵必須滿足介質(zhì)特性的要求:
a.對輸送易燃、易爆有毒或貴重介質(zhì)的泵,要求軸封可靠或采用無泄漏泵,如磁力驅(qū)動泵(無軸封,采用隔離式磁力間接驅(qū)動);
b.對輸送腐蝕性介質(zhì)的多級泵,要求對流部件采用耐腐蝕性材料,如氟塑料耐腐蝕泵 ;
c.對輸送含固體顆粒介質(zhì)的多級泵,要求對流部件采用耐磨材料,必要時軸封用采用清潔液體沖洗。
3、機(jī)械方面要求多級泵可靠性高、噪聲低、振動小。
4、正確計(jì)算多級泵采購的投入成本,包括采購成本和安裝維護(hù)成本。
