单级双吸中开泵 选型 型号 参数

页眉内容一 概述 S、SM、SF、SL、SY、SA、SAP、SAL、RS、XBD、XBC型泵为单级双吸水平中开式离心泵，供输送不含固体颗粒的清水或物理化学性质类似于清水的其它液体，被输送液体的温度为0摄氏度到80摄氏度。适用于工厂、矿山、城市给水、电站、农田排灌和各种水利工程。允许最大进口压力是0.6MPa二、产品特点 S、SM、SF、SL、SY、SA、SAP、SAL、RS、XBD、XBC型泵的吸入口与吐出口均在水泵轴心线下方。与曲线垂直成水平方向。检修时勿需拆卸进出口水管及电动机。 泵的主要零件泵体、泵盖、叶轮、轴、轴套、双吸密封环等，其中也轮、轴套、双吸密封环为损件。 叶轮用轴套和轴套螺母固定在轴上，其轴向位置可以通过轴套螺母进行调整，叶轮的轴向力通过其自身叶片对称布置达到平衡。 双吸密封环用以减小水泵压水室的水漏回吸水室。 泵的轴封分为填料密封和机械密封两种，轴承润滑方式分干油润滑和稀油润滑两种，当泵径为800mm以下基本采用干油润滑，泵口径为800mm以上基本采用稀油润滑。 泵通过弹性联轴器与电动机联接。 S型泵是单级双吸，卧式中开离心泵。型号意义： 以150S78A为例：150泵进口直径为150毫米S双吸离心泵78扬程为78米A叶轮外径第一次切割性能范围： 流量:14013000m3/h扬程:10134m口径:1501200mm三、 产品用途 供输送清水及物理化学性质类似于水的液体。液体最高温度不得超过80，适合工厂、矿山、城市、电站的给排水，农田排涝灌溉和各种水利工程(如下图）。 矿山、电站给排水、农田灌溉、工厂四、 性能参数型号流量Q( m3/h)扬程H(m)转速n(r/min)功率(KW)效率(%)汽蚀余量(NPSH)r(m)轴功率电机功率100S908090295030.137652.5100S90A72752330642.5150S10016010059.875733.5150S7816078455573.53.5150S78A1446233.845723.5150S501605027.337803.9150S50A1444020.930753.9150S50B1333618.622703.9200S952809591.711079.25.3200S95A2707573.590755.3200S632806358.37582.75.8200S63A2704645.155755.8200S422804238.14584.26200S42A2703633.137806250S6548565145010913278.63250S65A4685489.4110773250S394853961.57583.63.2250S39A46830.549.355793.2250S244852436.94585.83.5250S24A41420.327.637833.5250S144851421.53085.83.8250S14A4321115.818.5823.8300S110790110295.7440804300S9079090242.831579.64300S90A75678217280744300S90B72067180220734300S5879058149.918084.24.4300S58A72049118.6160814.4300S58B68443100132804.4300S327903279.211086.84.6300S32A7202660.775844.6300S1979019475586.85.2300S19A7201639.245805.2300S127901230.43784.85.5300S12A684103.930785.5350S125126012553471080.55.4350S125A1181112462630785.4350S125B109896373500775.4350S7512607530335585.25.8350S75A117065247280845.8350S75B108055197220825.8350S4412604417322087.56.3350S44A111636131160846.3350S2612602610213287.56.7350S26A111621.578.890836.7350S1612601664.57585.37.1350S16A104413.448.855487.1500S9820209597067880079.54500S98A18728354063078.54500S98B174674452560784500S59202059391450834.5500S59A187249333400754.5500S59B174640257315744.5500S35202035219280884.8500S35A174627151220854.8500S22202022144.1185845.2500S22A174617101132805.2500S1320201386.2110835.7600S75317075727800897.5600S75A288065580630887.5600S47317047465560887.5600S32317032310400897.5600S32A288027238280897.5600S22317022223280857.5600S22A288018.2168.520084.57.54页脚内容
