进口化工轴流泵概述
化工轴流泵参照升力线理论，吸取螺旋桨设计的经验，发展了沿径向变环量分布的轴流泵设计方法，并进行了厂内的模型试验，与同类相比，重量轻，体积小，刚性好，效率高等特点。
主要应用于大流量、低扬程的场合，特别适用于制盐、制碱的强制循环系统之中。
进口化工轴流泵结构特点
1、转速低，一般转速在980r/min以内，符合结晶工艺要求运行平稳.
2、水力性能优异，效率 〉70%高效区宽，抗汽蚀性能好.
3、考虑泵介质流动方向为垂直向下进，水平方向出。水流作用力对泵轴的巨大影响，在泵**增设了泵轴外套保护装置。使介质的俯冲作用力转移到泵体上，从而保证了泵的运行稳定，大大减轻了介质对机械密封作用力的影响，延长了机器封使用寿命。该结构的改进在国内同类产品中迈出了较大的一步。另外泵体采用整体式铸造刚性好，中间支承结构联结稳定.
4、 轴承箱部位为方型长跨距重型结构，稳定性好，承载能力强，运行可靠，与国内同类产品相比安装方便精确（原国内轴承箱为分体式）。前后两端分别采用径向短圆柱轴承和重型成对轴承。其轴承均采用INA（SKF）或国际优质轴承.
5、 封轴先进，采用副叶轮动力密封和博格曼快装式双端面机械密封组合，外接冷却冲洗水，改善轴封工作条件，机封寿命长。轴套外圆加大，与国内同类产品相比壁厚加厚变形小.
密封腔处的径向振摆小于0.05mm，保证了密封的可靠性和耐久性，延长了维修周期。可安装填料密封和单端或双端机械密封，并可安装动力密封以供特殊场合使用。

The import of chemical axial flow pump
British imports of chemical axial flow pump Chemical axial flow pump
Introduction of imported chemical axial flow pump
Hzw according to lifting line theory, draw propeller design experience, the development of the design method of axial flow pump with variable circulation distribution along the radial direction, and the model test is carried out and compared with the similar, light weight, small volume, good rigidity, high efficiency.
The utility model is mainly applied to the occasions of large flow rate and low lift, and is especially suitable for the forced circulation system of salt making and alkali making.
Structural characteristics of imported chemical axial flow pump
1, low speed, general speed within 980r/min, with the crystallization process running smoothly.
2, excellent hydraulic performance, high efficiency, wide area 70%, anti cavitation performance.
3, considering the flow direction of medium pump is vertically downward, a horizontal direction. The huge influence of the flow force on the pump shaft, and the pump shaft is additionally provided with a protective device for the shaft cover of the pump. So that the medium of the subduction force transferred to the pump body, thereby ensuring the stable operation of the pump, greatly reducing the effect of the medium on the mechanical seal force, extending the service life of the machine seal. The improvement of the structure has taken a big step in the domestic similar products. In addition the pump body adopts integral casting rigid, intermediate supporting structure coupling stability.
4, bearing box for square parts of long span and heavy structure, good stability, strong bearing capacity, reliable operation, compared with the domestic similar product installation is convenient and accurate (the original domestic bearing box split). The front and rear ends are respectively provided with a radial short cylindrical bearing and a heavy pair bearing. The bearings are made of INA (SKF) or international high quality bearings.
5, shaft sealing is advanced, the vice impeller dynamic seals and Bergman fast assembled double end mechanical seal combination, external cooling water, improve the working conditions of mechanical seal seal, long service life. The outer circle of the shaft sleeve is enlarged, and the wall thickness is thicker and the deformation is small compared with the domestic similar products
Seal radial vibration cavity pendulum is less than 0.05mm, to ensure the reliability and durability of sealing, prolong the maintenance period. Packing seal and single or double end mechanical seal can be installed and can be used for special occasions.
