产品概述: HW型泵为卧式、单级、单吸、涡壳式混流泵。
适用于输送清水或物理、化学性质类似于水的其它液体。
被输送的液体温度不宜高于50℃。
广泛用于农田排灌、工业和城市给排水等多种场合。
型号意义: 以300HW-8A为例
300——泵进、出口直径(mm)
HW——卧式涡壳混流泵
8——设计扬程(m)
A——切割叶轮外径或换用不同性能的叶轮。
性能范围: 流量:70~6500m3/h
扬程:4~20m
口径:150~900mm
结构特点: 1、HW型泵主要由泵盖、叶轮、泵体、泵轴、轴套及轴承体(口径≤350mm)或轴承架(口径≥400mm)等主要零件构成。
2、泵盖分别与泵体和进水管相接。泵盖平面与叶轮平面之间应有适当间隙。间隙过小会产生摩擦;间隙过大,会导致泵体内的压力水大量回流、使泵的效率降低。实际使用的适宜间隙为0.3-0.7mm(将泵轴推向泵的进口端),间隙可用增减纸垫厚度来调整。
3、轴封装置由填料、填料压盖、填料环和泵体上的调料函组成(150HW和200HW型泵无填料环)。其作用是防止空气吸入泵内和防止水从泵内过多地沿轴流出。?HW,HBC型涡壳式混流泵性能参数表泵型号流量Q扬程H(m)转速n(r/min)口径(mm)效率η(%)功率N(kW)临界气蚀余量(NPSH)c(m)重量W(kg)(m3/h)(L/S)吸入排出轴功率配带功率150HW-51805051450150150822.9942.760150HW-61805061450150150823.595.5368:223629.21800150150827.077.5468150HW-81805081450150150824.785.52.760150HW-121805012.52900150150827.4711655200HW-53601005145020020081.56.017.54105200HW-83601008145020020083.59.39114105200HW-103601007120020020083.58.22114130:45012510145020020083.514.6818.55130:50013912.2160020020083.519.91305.5130200HW-1236010012.5145020020083.514.6818.54105250HW-554015051180250250828.97114190250HW-745012579802502508410.22154168250HW-84441235.4970250250847.78112.7190:540150811802502508414.0118.54190:66418412.114502502508426306.4190250HW-114501524.8980250250847114169:65018011.614502502508424.37306169:72020014.316002502508433.38376.5169250HW-1254015012.511802502508421.88304190300HW-579222059703003008312.99154230300HW-879222089703003008520.3224230300HW-8A5811613.9730300300847.48113230:78021779803003008418.08224230:103528812.313003003008442.17555230300HW-1279222012.59703003008531.72374230350HW-87452074.473035035085.510.44154330:1000278898035035085.525.5305330400HW-712603506.87304004008627.13304486:169247012.39804004008665.9755486400HW-1014003899.947304004008644.3554496:18805221898040040086107.11105496500HW-619805506.25805005008738.4555.5770:24926929.87305005008776.4956770650HW-533129205.14856506508554.1755.51940:403211207.555906506508597.511561940650HW-734009446.54506506508868.4905.31940.366310177.64856506508886.11005.51940.4457123811.1859065065088154.218061940650HW-10400011111459065065088173.318061940.33229239.74906506508899.71155.51940700HW-8450012507.849070070088108.71304.5.800HW-105980166112.2490800800882252505.53433800HW-167200200017.759080080088394.64506.534331200HW-2.5960026672.5154120012008874.3100298501200HW-6.61558443296.62501200120088318350498501200HW-9.61870051949.5300120012008855063069850
