一、IS型清水离心泵结构说明：IS型清水离心泵为后开式，拆开泵盖和叶轮时不需拆卸吸水和排出管路。悬架内装有两个滚珠轴承，用机器油或润滑脂润滑。泵通过弹性联轴器由电动机直接驱动。涡室、脚、进水法兰和出水法兰铸成一个整体。二、IS型清水离心泵装配与拆卸：泵在装配前应首先检壹零件有无影响装配的缺陷，并擦洗干净，方可进行装配。1、予先可将各处的连接螺栓，丝堵等分别拧紧在相应的零件上。2、予先可将0形密封圈、纸垫、毛毡等分别放置在相应的零件上。3、予先可将密封环和填料、填料环、填料压盖等依次装到泵盖内。4、将滚动轴承装到轴上，然后装到悬架内，再合上压盖，压紧滚动轴承，并在轴上套上连接螺栓。5、将轴套装在轴上，再将泵盖装在悬架上，然后再将叶轮、止动垫围。叶轮螺母等装上并拧紧。最后将上述组件装到泵体内，并拧紧泵体、泵盖上的连接螺栓。在上述装配过程中，一些小件如平键、档油盘、档水?轴套内0形密封围等容易遣漏或装钳顺序，应特别注意。泵拆卸顺序基本上可按装配顺序的反向进行。安装泵安装的好坏对泵的运行和寿命有重要影响，所以安装和校正必须仔细进行。泵的外形及安装尺寸。1、安装和校正：1)清除底座上的油腻和污垢，把底座放在地基上。2)用水平仪检查底座的水平度，允许用楔铁找平。3)用水泥浇灌底座和地脚螺栓孔眼。4)水泥干固后应检查底座和地脚螺栓孔眼是否松动，合适后拧紧地脚螺栓，重新检查水平度。5)清理底座的支持平面，水泵脚及电机脚的平面，并把水录和电机安装到底座上去。6)联轴器之间应保持一定的间隙，检查水泵轴和电机轴中心线是否一致，可用薄垫片调整使其同心。测量联轴器的外园上下，左右的差刖不得超过0.1mm，两联轴器端面间隙一周上最大和最小的间咪差别不得超过0.3mm2、安装说明：1)泵的安装高度，管路的长度。直径、流速应符合计算，力求减少不必要的损失。2)长距输送时应取较大的管径，泵的管路应有自己的支架，不允件管路的重量加在泵上，避免把泵压坏。3)排出管路如装逆止阀应装在闸阀的外面。三、IS、IR型卧式单级单吸清水离心泵起动停止与运转：1、起动：1)应在机^联结前确定是电动机的旋转方向是否正确，泵的运转是否灵活。2)关闭吐出管路上的闲阀。3)向泵内灌满水，或用真空泵引水。4)接通电源，当泵达到正常转速后，再逐渐打开吐出管路上的闸阀，并调节到所需要的工况，在吐出管上的闸阀关闭的情况下，泵连续工作的时间不得超过3分钟。2、停止：1)逐渐关闭吐出管路上的闸阀，切断电源。2)如环境温度低于0℃，应将泵内水放出，以免冻裂。3)如长期停止使用，应将泵拆卸清洗上油，包装保管。3、运转：1）在开车及运转过程中，必须注意观察仪表读数，轴承发热，填料漏水和发热及的振动和杂音等是否正常，如果发现异常情况，应即时处理。2）轴承温度最高不大于80℃，轴承温度不得比周围温度超过40℃。3)填料正常，漏水应该是少量均。4)轴承油位应保持在正常位置上，不能过高或过低，过低时应及时补充润滑油。5)如密封环和叶轮配合部位的间隙磨损过大应更换新的密封环。泵型号Type流量Capacity扬程Headm转速Speedr/min功率Power(Kw)效率%汽蚀余(NPSH)m重量Weighkgm3/hl/s轴Shaft电机MotorIS(R)50-32-12512.53.472029001.132.2602.072IS(R)(R)50-32-125A11.23.11160.841.5582.0IS(R)(R)50-32-1256.31.74514500.160.75542.0IS(R)(R)50-32-125A5.61.5640.120.75522.0IS(R)(R)50-32-16012.53.473229002.023542.076IS(R)(R)50-32-160A11.73.25281.723522.0IS(R)(R)50-32-160B10.83.01241.412.2502.0IS(R)(R)50-32-1606.31.74814500.280.75482.0IS(R)(R)50-32-160A5.91.6470.240.75462.0IS(R)(R)50-32-160B5.41.560.200.75442.0IS(R)(R)50-32-20012.53.475029003.545.5482.081IS(R)(R)50-32-200A11.73.25443.044462.0IS(R)(R)50-32-200B10.83.01382.544442.0IS(R)(R)50-32-2006.31.7412.514500.511.1422.0IS(R)(R)50-32-200A5.91.64110.441.1402.0IS(R)(R)50-32-200B5.41.59.50.370.75382.0IS(R)(R)50-32-25012.53.478029007.1611382.0154IS(R)(R)50-32-250A11.73.25706.1911362.0IS(R)50-32-250B10.83.01605.197.5342.0IS(R)50-32-2506.31.742014501.071.5322.0IS(R)50-32-250A5.91.6417.50.941.5322.0IS(R)50-32-250B5.41.5150.791.1282.0IS(R)65-50-125256.942029001.973692.078IS(R)65-50-125A22.46.22161.462.2692.0IS(R)65-50-12512.53.47514500.270.75642.0IS(R)65-50-125A11.23.1140.200.75642.0IS(R)65-50-160256.943229003.355.5652.084IS(R)65-50-160A23.46.5282.834632.0IS(R)65-50-160B21.76.03242.324612.0IS(R)65-50-16012.53.47814500.450.75602.0IS(R)65-50-160A11.73.2570.380.75582.0IS(R)65-50-160B10.83.0160.320.75562.0IS(R)65-40-200256.945029005.677.5602.088IS(R)65-40-200A23.46.5444.837.5582.0IS(R)65-40-200B21.76.03384.005.5562.0IS(R)65-40-20012.53.4712.514500.771.5552.0IS(R)65-40-200A11.73.25110.661.1532.0IS(R)65-40-200B10.83.019.50.551.1512.0IS(R)65-40-250256.9480290010.315532.0172IS(R)65-40-250A23.46.5708.7411512.0IS(R)65-40-250B21.76.03607.2311492.0IS(R)65-40-25012.54.472014501.422.2482.0IS(R)65-40-250A11.73.2517.51.212.2462.0IS(R)65-40-250B10.83.01151.001.5442.0IS(R)65-40-315256.94125290021.330402.5200IS(R)65-40-315A23.96.6411419.33038.52.5IS(R)65-40-315B22.76.3010317.222372.5IS(R)65-40-315C21.45.949215.322352.5IS(R)65-40-31512.53.473214502.944372.5IS(R)65-40-315A11.93.3228.52.6435.52.5IS(R)65-40-315B11.33.1525.82.334342.5IS(R)65-40-315C10.72.94232.094322.5IS(R)80-65-1255013.92029003.635.5753.087IS(R)80-65-125A44.712.43162.674733.0IS(R)80-65-125256.94514500.480.75712.5IS(R)80-65-125A22.46.2240.350.75692.5IS(R)80-65-1605013.93229005.977.5732.597IS(R)80-65-160A46.813.0285.027.5712.5IS(R)80-65-160B43.312.04244.105.5692.5IS(R)80-65-160256.94814500.791.5692.5IS(R)80-65-160A23.46.5570.671.1672.5IS(R)80-65-160B21.76.0360.551.1652.5IS(R)80-50-2005013.95029009.8715692.5100IS(R)80-50-200A46.813448.3711672.5IS(R)80-50-200B43.312.04386.8911652.5IS(R)80-50-200256.9412.514501.312.2652.5IS(R)80-50-200A23.46.5111.12.2632.5IS(R)80-50-200B21.76.039.50.921.5612.5IS(R)80-50-2505013.980290017.322632.5156IS(R)80-50-250A46.8137014.6218.5612.5IS(R)80-50-250B43.312.046012.0015612.5IS(R)80-50-250256.94td>2014502.273602.5IS(R)80-50-250A23.46.517.51.923582.5IS(R)80-50-250B21.76.03151.582.2562.5IS(R)80-50-3155013.9125290031.537542.5206IS(R)80-50-315A47.513.2511428.193752.52.5IS(R)80-50-315B45.412.610324.9630512.5IS(R)80-50-315C42.911.992290021.9330492.5206IS(R)80-50-31525.06.943214504.195.5522.5IS(R)80-50-315A23.86.6228.53.595.551.52.5IS(R)80-50-315B22.76.325.83.194502.5IS(R)80-50-315C21.45.94232.794482.5IS(R)100-80-12510027.8202900711784.5101IS(R)100-80-125A89.424.83165.127.5764.5IS(R)100-80-1255013.9514500.911.5752.5IS(R)100-80-125A44.712.4240.671.1732.5IS(R)100-80-16010027.832290011.215784.0161IS(R)100-80-160A93.526289.3815764.0IS(R)100-80-160B86.624.1247.6511744.0IS(R)100-80-1605013.9814501.452.2752.5161IS(R)100-80-160A46.81371.191.5732.5IS(R)100-80-160B43.312.0460.941.5712.5IS(R)100-65-20010027.850290017.922763.6149IS(R)100-65-200A93.5264415.1318.5743.6IS(R)100-65-200B86.624.1381
