MD280-43X7矿山用泵,多级矿用泵具体的参数介绍.doc

MD型单吸多级离心清水泵MD280-43*7矿山用泵概述： MD型泵为单吸、多级、节段式离心清水泵。适应于矿山、工厂及城市给排水，用来输送不含固体颗粒的清水或物理、化学性质类似于清水的液体，被输送的介质温度为080，允许进口压力0.6MPa。MD280-43*7矿山用泵参数范围：流量Q 10500m3/h扬程H 33850mMD280-43*7矿山用泵型号说明：MD型泵在型号表示方法上有三种，现分述如下：1）MD12-25*5“MD”表示多级MD280-43*7矿山用泵。“12”表示泵的流量（m3/h）。“25”表示泵的单级扬程（m）。“5”表示级数。2）MD80-305多好呀“MD”表示单级、多吸、节段式离心清水泵。“80”表示泵的吸入口直径（mm）。“30”表示泵的单级扬程（m）。“5”表示级数。这种方法表示的泵只有MD8030。3）150MD305“150”表示泵的吸入口直径（mm）。“MD”表示单级、多吸、节段式离心清水泵。“30”表示泵的单级扬程（m）。“5”表示级数。MD280-43*7矿山用泵结构型式：MD型泵为卧式安装，所有MD型泵的吐出口方向垂直向上。轴向力由平衡盘来平衡。轴封一般采用填料密封，根据用户需要也可采用机械密封。除MD85-67，MD155-67型泵采用滑动轴承、稀油润滑外，其余采用滚动轴承、油脂润滑。MD280-43*7矿山用泵的装配清洗和检查：a、用没有清洗全部的零件，在空气中干燥或用布擦干；b、检查全部零件的磨损情况，对不能确保正常运转的零件应更换新的；c、检查泵轴是否有灰尘或生锈，用千分表检查轴的不宜度（轴的径向跳动值不大于8级精度）；MD、当密封间隙超过推荐值的最大值50%时，应更换密封元件。泵的装配顺序一般是按拆卸顺序反向进行；本型泵装配质量的好坏直接影响泵能否正常运行，并影响泵的使用寿命和性能参数；影响机组的振动和噪音。装配中应注意以下几点：a、固定部分各零件组合后的同心度靠零件制造精度和装配质量来保证，应保护零件的加工精度和表面粗糙度、不允许磕碰、划伤。作密封剂用的二硫化钼应干净，紧固用的螺钉、螺栓应受理均匀。b、叶轮出口流道与倒也进口流道的对中性是依各零件的轴向尺寸来保证。流道对中性的好坏直接影响泵的性能，故泵的尺寸不能随意调整。c、泵装配完毕后，未装填料前，用手动转动泵转子，检查转子在壳体内旋转是否灵活，转向窜动量是否达到规定要求。MD、上述检查符合要求后，在泵两端轴封处加入填料，注意填料环在填料室中的相置。MD280-43*7矿山用泵旋转方向：从电机端向泵看为顺时针方向旋转。MD280-43*7矿山用泵主要零件材质： 泵的过流部件材质均为铸铁，轴的材质为45号钢。MD280-43*7矿山用泵成套范围：泵于电机、底座配套供应，可配功用底座或本身底座，厂方还提供附件（包括吐出锥管、闸阀、底阀、止回阀）和备件（包括叶轮、密封环、导叶套、平衡盘、轴套）。MD280-43*7矿山用泵的拆卸拆卸时应严格保护零件的制造精度不受损伤：拆卸穿杆的同时应将各中段用垫垫起， 以免各中段止口松动下沉将轴压弯MD280-43*7矿山用泵注意亊项：a、将泵壳内的液体放掉：b、如果轴承部件是稀油润滑时应将润滑油放掉；C、拆去妨碍拆卸的附属管路，如平衡管、水封水管等管路和引线，拆卸顺序：泵的拆卸步骤应从拆下吐出側的轴承部件开始，其顺序大致如下（因泵的结构有所差别.在拆卸过程中会略有不同）:a、柠下吐出侧轴承压盖上的螺栓和吐出段、填料函体、轴承体三个件之间的联接螺母卸下轴承部件：b、拧下轴上的圆螺母，依次卸下轴承内圈、轴承压盖和挡套后，卸下填料体（包括填料压盖、填料环和填料等）：c、依次卸下轴上的O型密封较圈、轴套、平衡盘和键后，卸下吐出段（包括末级导叶、 平衡环等）;MD、卸下末级叶轮和键后，卸下中段（包括导叶）：按同样方法继续卸下其余各级的叶 轮、中段和导叶，直到卸下首级叶轮为止：e、拧下吸水段与轴承体的联接螺母和轴承压通上的螺栓后，卸下轴承部件（在这之前 应先将泵联轴器卸下）；f、将轴从吸入段中抽出，拧下轴上的固定螺母，依次将轴承内圈、O型密封圈、轴套和挡套等卸下。至此拆卸工作基本完成，但在上述拆卸过程中，还有部分零件时相互联接在一起的，一般情况下拧下联接螺栓或螺母后可卸下。参数型号流量Q扬程H转速n轴功率Pa配带电动机效率必须汽蚀余量叶轮名义直径进出口径泵重功率型号m3/sL/smr/minkwkw%mmmmmkgMD16-6031016202.784.445.55186183177298016.919.921.930Y200L1-23040442.32.83.42096550170MD16-6041016202.784.445.55248244236298022.526.629.237Y200L2-23040442.32.83.42096550190MD16-6051016202.784.445.55310305295298028.233.336.545Y225M-23040442.32.83.42096550210MD16-6061016202.784.445.55372366354298033.839.943.855Y250M-23040442.32.83.42096550230MD16-6071016202.784.445.55434427413298039.446.651.575Y280S-23040442.32.83.42096550250MD16-6081016202.784.445.5549648847229804552.358.475Y280S-23040442.32.83.42096550270MD16-6091016202.784.445.55558549531298050.759.965.790Y280M-23040442.32.83.42096550290MD16-60101016202.784.445.55620610590298056.366.573.190Y280M-23040442.32.83.42096550310MD16-60111016202.784.445.55682671649298061.973.280.3110Y315S-23040442.32.83.42096550330MD16-60121016202.784.445.55744732708298067.669.887.6110Y315S-23040442.32.83.42096550350MD16-60131016202.784.445.55806793767298073.286.594.9132Y315M-23040442.32.83.42096550370MD16-60141016202.784.445.55868854826298078.893102.3132Y315M-23040442.32.83.42096550390MD25-5031525284.166.947.78154.5150144298014.318.920.330Y200L1-24454542.42.72.8196808027072参数型号流量Q扬程H转速n轴功率Pa配带电动机效率必须汽蚀余量叶轮名义直径进出口径泵重功率型号m3/sL/smr/minkwkw%mmmmmkgMD25-5041525284.166.947.78206200192298019.125.227.137Y200L2-24454542.42.72.81968080295MD25-5051525284.166.947.78257.5250240298023.931.533.937Y200L2-24454542.42.72.81968080315MD25-5061525284.166.947.78309300288298028.637.840.745Y250M-24454542.42.72.81968080340MD25-5071525284.166.947.78360.5350336298033.444.147.555Y250M-24454542.42.72.81968080360MD25-5081525284.166.947.78412400384298038.250.454.275Y280S-24454542.42.72.81968080385MD25-5091525284.166.947.78463.545043229804356.76175Y280S-24454542.42.72.81968080405MD25-50101525284.166.947.78515500480298047.76367.875Y280S-24454542.42.72.81968080430MD25-50111525284.166.947.78566.5550528298052.569.374.690Y280M-24454542.42.72.81968080450MD25-50121525284.166.947.78610600576298057.375.681.4110Y315S-24454542.42.72.81968080475MD46-5032846507.7812.7813.89172.5150144298024.829.33137Y200L2-2536363.22.52.832088080270MD46-5042846507.7812.7813.89230200192298033.139.841.345Y225M-2536363.22.52.832088080295MD46-5052846507.7812.7813.89287.5250240298041.449.851.675Y280S-2536363.22.52.832088080315MD46-5062846507.7812.7813.89345300288298049.659.761.975Y280S-2536363.22.52.83208808034073参数型号流量Q扬程H转速n轴功率Pa配带电动机效率必须汽蚀余量叶轮名义直径进出口径泵重功率型号m3/sL/smr/minkwkw%mmmmmkgMD46-5072846507.7812.7813.89402.5350336298057.969.772.290Y280M-2536363.22.52.832088080360MD46-5082846507.7812.7813.89460400384298066.279.682.690Y280M-2536363.22.52.832088080385MD46-5092846507.7812.7813.89517.5450432298074.489.692.9110Y315S-2536363.22.52.832088080405MD46-50102846507.7812.7813.89575500480298082.999.5103.2132Y315M1-2536363.22.52.832088080430MD46-50112846507.7812.7813.89632550528298089.7109.5113.5132Y315M1-2536363.22.52.832088080450MD46-50122846507.7812.7813.89690600576298099.3119124160Y315L1-2536363.22.52.832088080475MD85-673558510015.2523.6127.78222201183298061.571.576.690Y280M-25465653.344.4235150150840MD85-674558510015.2523.6127.78296268244298082.195.4102.2110Y315S-25465653.344.4235150150964MD85-675558510015.2523.6127.783703353052980102.5119.3127.2132Y315M1-15465653.344.42351501501126MD85-676558510015.2523.6127.784444023662980123.1143.1152.8160Y315M2-25465653.344.42351501501434MD85-677558510015.2523.6127.785184694272980143.6166.9178.8200Y3152-2(ip44)5465653.344.42351501501624MD85-678558510015.2523.6127.785925364882980164.1190.8204.3220Y315M1B-25465653.344.42351501501624MD85-679558510015.2523.6127.786666035492980184.6214.6230250Y315M2B-25465653.344.4235150150184074参数型号流量Q扬程H转速n轴功率Pa配带电动机效率必须汽蚀余量叶轮名义直径进出口径泵重功率型号m3/sL/smr/minkwkw%mmmmmkgMD155-6739515518526.3843.0651.38228201177298093.6114.7122.1132Y315M1-26374732.64.55.723515015952MD155-6749515518526.3843.0651.383042682362980124.8152.9162.8185Y315SB-26374732.64.55.7235150151024MD155-6759515518526.3843.0651.383803352952980156191.1203.6220Y315M1B-26374732.64.55.7235150151145MD155-6769515518526.3843.0651.384564023542980187.2229.3244.3280Y355M2-2(ip23)6374732.64.55.7235150151435MD155-6779515518526.3843.0651.385324694132980218.4267.6285315Y355M3-2(ip23)6374732.64.55.7235150151558MD155-6789515518526.3843.0651.386085364722980249.6305.8325.7355Y355M1-2(ip23)6374732.64.55.7235150151700MD155-6799515518526.3843.0651.386846035312980280.8344366.4400Y400-26374732.64.55.7235150151860MD80-3032643487.211.913.3102908329801215.115.918.5Y160L-260707933.94.31628080135MD80-3042643487.211.913.313612011129801620.121.222Y180M-260707933.94.31628080150MD80-3052643487.211.913.3170150139298020.125.226.530Y200L1-260707933.94.31628080165MD80-3062643487.211.913.3204180167298024.130.231.837Y200L2-260707933.94.31628080175MD80-3072643487.211.913.3238210195298028.135.237.145Y225M-260707933.94.31628080190MD80-3082643487.211.913.3272240222298032.140.242.455Y2
