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。

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%GX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。

Chemical axial flow pump inlet chemical axial flow pump imported from Germany pump axial flow pump Chemical axial flow
Overview of 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 axial flow pump
1, low speed, the general speed of less than 980r/min, in line with the requirements of the crystallization process running smoothly
2, excellent hydraulic performance, efficiency of the 70% high efficiency area, good anti cavitation performance
3, taking into account the direction of the flow of the pump into the vertical downward direction, the 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 the integral casting rigidity, and the middle supporting structure is connected stably
4, the bearing box for the square long span heavy structure, good stability, bearing capacity, reliable operation, compared with the domestic similar products to facilitate the installation of precision (the original bearing box for split type). The front and rear ends are respectively provided with a radial short cylindrical bearing and a heavy pair bearing. The bearings are INA (SKF) or international quality bearings
5, sealing the axis of advanced, the use of auxiliary impeller power seal and Bergman fast mounted double face mechanical seal combination, external cooling water, improve the shaft seal working conditions, machine seal life is long. 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
The radial vibration of the seal cavity is less than 0.05mm, which guarantees the reliability and durability of the seal and prolongs the maintenance period. Packing seal and single or double end mechanical seal can be installed and can be used for special occasions.
Chemical axial flow pump:
The utility model is suitable for the occasions of large flow and low lift, and is especially suitable for the forced circulation system of salt making and alkali making.
Performance parameters of axial flow pump
Flow: 300-1100m3/h
