单级双吸清水离心泵.pdf

S 型泵简介E- mail:eastpump@1产品简介S型单级双吸离心泵是新型节能卧式中开泵，供输送清水或物理化学性质类似于水的其他液体，根据用户需求，通过改变泵结构及材质可用于输送多泥砂水或各类腐蚀性液体，该系列泵适用于工厂、矿山、城市给排水、电站、农田排灌及各种水利工程型号意义300单级双吸离心泵A车小叶轮外径相应改变泵型扬程90mS90吸入口直径300mmI过流部件材料代号—装配与拆卸装配转子部件：依次将叶轮、轴套、轴套螺母、填料套、填料环、填料压盖、挡水圈、轴承部件装在泵轴上，并套上双吸密封环，然后装上联轴器；将转子部件装在泵体上，调整叶轮的轴向位置到双吸密封环的中间加以固定，将轴承体压盖固定螺钉紧固；装上填料，放好中开面纸垫，盖上泵盖打紧螺尾柱销后，拧紧泵盖螺母，最后装上填料压盖但不要将填料压得太紧，填料过紧会使轴套发热，耗费功率较大，也不要压得太松，过松会使液体渗漏大，水泵效率降低；装配完成后，用手转动泵轴，没有擦碰现象，转动比较轻滑均匀即可，拆卸可按上述装配顺序相反进行结构说明本型泵的吸入口与吐出口均在水泵的轴心线的下方，与轴线垂直成水平方向检修时无需拆卸进出口水管及电机。

从传动方向看去，水泵为顺时针方向旋转（根据用户需要亦可改为逆时针方向旋转）泵主要零件有：泵体、泵盖、叶轮、轴、双吸密封环、轴套等；泵体与泵盖构成叶轮的工作室在进出水法兰上，制有安装真空表和压力表的管螺孔进出水法兰的下部，制有放水的管螺孔；经过静平衡校验的叶轮，用轴套和两边的轴套螺母进行调整；泵轴由两个单列向心球轴承支承轴承装在轴承体内、安装在泵体两端，用黄油润滑；双吸密封环用以减少水泵压水室的水漏回吸水室；泵通过弹性联轴器由电动机直接传动，必要时亦可用内燃机传动；轴封为软填料密封（根据用户需要可采用机械密封结构）S 型泵结构图及材料表E- mail:eastpump@2结构图21346578910过流部件主要材料代号表序号名称1泵体2泵盖3叶轮4轴56轴套7联轴器8轴承体9填料压盖10填料双吸 密封环材料代号材料牌号IMT- 4II1Cr18Ni9TiIII1Cr18Ni12Mo2Ti未注HTE- mail:eastpump@3Type泵型号Q m /h()3流量150S78150S78A150S50150S50A150S50B200S95200S95A200S95B200S63200S63A200S42200S42A250S65250S65A250S39250S39A250S24250S24A250S14250S14A300S90300S90A300S90B300S58300S58A300S58B300S32300S32A300S19300S19A300S12轴功率电机功率功率(kW)Head (m) 扬程r/min转速效率%η(NPSH)r (m) 气蚀余量重量(kg)295029502950295029502950295029502950295029502950145014501450145014501450145014501450145014501450145014501450145014501450145055453730221321109075554537132110755545373018.531528022020016013290755545373.73.73.93.93.95.35.35.35.85.8663.13.13.23.23.53.53.83.84.24.24.24.44.44.44.64.65.25.25.51401401301301302602602602302301801804854853803803653653203208408408408108108107107104884886671261601988278704045527075.572 11214418067625530.133.438.56872.670 13016022052504025.227.331.17380.477 11214418044403518.620.024.57275.570 10813316038363217.218.019.46572.572 183280324103958783.191.4102.46279.275 18027032492857867.383.394.3677573 18026030682756864.873.880.9627270 21628035169635354.858.366.77482.776 18027032454463737.845.146.6707570 21628032448423534.838.140.28184.281 19827031043363130.533.134.4768076 36048561271655892.8109.2130.67578.674 3424205406148507788.5987477.775 36048561242393254.261.567.57683.679 32446857635302541.748.450.9747977 36048557627241933.136.936.48085.882 32441448222201725.627.227.98083.380 36048557616141119.621.522.18085.578 3204325041311814.515.214.67882.775 5907909369390822022432797479.675 576756918867870190216.42477174.271 540720900726757151180200707370 576790972635850131.8147.9165.57584.280 529720893534942100.5118.0130.97682.578 50468483546433787100108738078 6127909003632287579868086.880 55172081031262458.160.767.9808478 61279093522191645.947.147.98086.885 50472082920161338.739.239.1718075 61279090014121029.230.433.18084.874S 型泵性能参数表性能参数表E- mail:eastpump@Type泵型号Q m /h()3流量300S12A350S125350S125A350S125B350S75350S75A350S75B350S44350S44A350S26350S26A350S16350S16A400S90400S90A400S90B400S40400S40A400S40B500S98500S98A500S98B500S59500S59A500S59B500S35500S35A500S322500S22A500S13600S22轴功率电机功率功率(kW)Head (m) 扬程r/min转速效率%η(NPSH)r (m) 气蚀余量重量(kg)1450145014501450145014501450145014501450145014501450145014501450970970970970970970970970970970970970970970970307105604003552802202201601329075555604503151851601108006305604504003152802201851321102505.55.45.45.45.85.85.86.36.36.76.77.17.16.26.26.25.15.15.14.14.14.14.54.54.54.84.85.25.25.77667158015801580120012001200110511058758757607601950195019501940194019402400240024002235223522351640164015551555150525005226847921110821.723.922.77278.476 850126016601401251004635336287080.572 80311811570125112903914615507078.270 745109814581089677313373425707772 9721260144080756527130331978.585.280 90011701332706556220244.42577884.279 82810801224595547177.4196.3203.57582.477 92712601476504437163.4172.5188.38187.579 86411161332413630121129.51368084.580 97212601440302622991021058087.582 8641116129626211676.576.977.48083.473 9721260144020161363.864.468.97385.474 864104412601613105147497478.370 135016201800969085458.2473508788482 121514601621787369327345371.3798482 108413001445625855223245264828482 90010801260424037129140150808584 8151007108435333195.81071098184.584 725870967282624.767.373.378.4828483 1620202023401149879664.8678.1680.37879.574 1500187221709683675095395427778.573 140017462020867459431.4450.1432.87678.775 162020202340675947374388.23747983.680 150018722170574939315332.33207475.672 140017462020464032240255.8248737471 162020202340403528207.6218.2209.98588.285 140017462020312721144150.61388285.284 162020202340242219137.5143.6142.47784.285 140017462020201714103100.6947480.382 16202020234015131083.885.779.77983.480 252031703600252218209.2215.8215.2828882S 型泵性能参数表性能参数表E- mail:eastpump@S 型泵性能参数表5性能参数表Type泵型号Q m /h()3流量600S22A600S32600S32A600S47600S47A600S75600S75A600S75B600S100600S100A600S100B800S22800S22800S22A800S22A800S32800S32800S32A800S32A800S47800S47800S47A800S47A800S76800S76800S76A800S76A800S76B800S76B轴功率电机功率功率(kW)Head (m) 扬程r/min转速效率%η(NPSH)r (m) 气。
