黑龙江高效自平衡多级离心泵

1、ZD型高效节能自平衡多级泵概述ZD型自平衡多级泵是长沙宏力水泵厂为满足用户需求而设计的一种高效、节能及使用寿命长的先进型多级离心泵产品，采用国外高效、节能水利模型，改变了传统多级泵带平衡装置的设计，并加速了高压多级泵的技术发展。依据API610标准研发制造，在行业内居于技术领先地位。具有高效区宽、性能范围广、汽蚀性能好、运转安全和平稳、噪音低、易损件少，安装维修方便等优点。ZD型高效节能自平衡多级泵将传统的结构形式进行了改革创新，取消了多级离心泵的轴向力平衡机构，取消了平衡盘装置，是D、DG型多级离心泵最好的更新换代产品。ZD型高效节能自平衡多级泵由于无平衡装置，即无平衡盘的圆盘摩擦损失又无平

2、衡水的回流损失，所以泵效率比同类别多级泵提高514%,在平衡盘无磨擦的情况下降低了泵的轴功率，从而达到了一个节能的效果，所以泵运行时的耗电量同比同类别多级泵节能3%左右。同时彻底解决因平衡装置失效而导致平衡盘和平衡环的磨损或转子咬死等各种故障，它的设计延长了泵的使用寿命。无故障运行时间是普通泵的3倍以上，用户维修成本大大降低，从而降低泵的寿命周期成本。多年的运行证明，该产品性能达到国际同类产品的先进水平。可用于输送颗粒含量w1.5%,颗粒1.3mm,温度105C的清水或物理化学性质类似于清水的其它液体。也可通过改变泵的材质（和结构）、密封形式和增加冷却系统用于输送温度W225C热水、油类、腐蚀

3、性或含磨料的介质等。材质有HT200、QT600、ZG、304、304L、316L、317L、904L、CD4等各种材质可供用户选。性能特点1）高效节能：采用先进的水力模型，自主研发高效节能产品；由于泵转子没有了平衡盘的磨损及轴向脉动，叶轮与导叶的对中性总是处于最佳状态，不会像普通多级泵结构随平衡盘的磨损、转子部件前移而出现效率明显下降；且没有了平衡水的泄露，减少了容积损失，在整体上提高了泵的运行效率，降低了轴功率，比普通多级泵效率平均高2%-3%；2）新结构：具有对称布置的叶轮转子部件，各级对称叶轮所产生的轴向力相互抵消，无需采用平衡盘结构就能实现泵腔内巨大轴向推力的自动平衡，突破了多级泵的

4、传统结构；3）新技术：独有的节流、减压装置，奇数级平衡装置，还能起到辅助支承作用；4）高可靠性：叶轮的对称布置，使运行中产生的轴向推力基本得到自相平衡，从而不需要小间隙、高压降、易冲刷、易磨损、易出故障的平衡盘装置，使轴向力载荷对泵的磨损和对系统干扰的不利影响降到最小。残余轴向力由推力轴承承受，这样使泵轴始终处于受拉状态、轴的受力状态均匀，且应力峰值较原型结构大大降低，从而提高了泵转子的刚性和临界转速，使泵转子运行的平稳性和可靠性显著提高；5）汽蚀性能好，使用寿命长：优化的水力及结构设计、精密的铸造、可靠的耐磨材质，部分型号泵首级叶轮采用双吸结构，使泵具有良好的抗汽蚀性能，整机运转平稳、噪音低

5、、使用寿命长；6）机封强可靠性：泵启、停时转子部件没有轴向窜动，工作时没有轴向脉动，克服了一直困扰多级泵的机封可靠性差这一难题；7）应用广泛：取消了小间隙平衡盘，比传统多级泵结构适应介质性质更为恶劣的场合；8）维护成本低：采用精密铸造，减少了易损件部件及维修拆装次数，延长了产品寿命，最大限度地避免了由于拆装过多引起的一系列问题，降低了维护成本；9）检修方便：产品整机采用三维设计、转子部件数控加工，严格保证了各部件的加工尺寸和加工精度；定位精确，一般技术人员只要按总装图的装配顺序和要求即可完成；完全避免了老式多级泵必须专业人员才能调整定位轴向蹿动尺寸，带给用户极大的便利。型号说明例：ZD280J
