CFY型泵是一种单级单吸长轴液下式磁力驱动离心泵，适合于石油、化工行业输送不含固体颗粒的各类易于挥发的有毒有害液体。

广泛应用于氟化工行业氢氟酸液下泵和LNG行业的胺收集液下泵等。

CFY is a single stage single suction long shaft submerged magnetic driven centrifugal pump, suitable for conveying all types of volatile toxic and harmful liquids free of solid particles in petroleum and chemical sectors.

It is used extensively as submerged pump for hydrofluoric acid in fluorine chemical sector and for amine collecting liquid in LNG operations.

结构说明Description of structure

1.单级、单吸、立式。

2.滑动轴承采用输送介质自润滑；材质为碳化硅陶瓷、石墨、碳化钨等耐磨材料。

3.较高扬程的泵采用双蜗壳结构，使转子部件受径向力小，轴挠度小。

4.泵的吸入口顺着轴线方向，排出口与轴线平行。

5.驱动端的泵轴由轴承盒内的滚动轴承支承，滚动轴承以黄油润滑。

6.泵的内置滑动轴承用所输送的液体润滑。

7.泵工作时液面必须高于叶轮中心线，叶轮浸没在介质中，不存在排空问题。

8.泵主要由泵体、泵盖、叶轮、轴、联轴器、中间接管、出液管、轴承架、底板等零件组成。

9.泵的立式电机通过弹性联轴器与泵直接传动，泵的整体通过底板安装在容器上。

10.该泵型可在高压工况中运行，工作压力4.0MPa。

1.Single-stage, single-suction vertical pump.

2.The sliding bearings are self-lubricated by conveying medium, in wearing-resisting materials such as silicon carbide ceramics, graphite and tungsten carbide.

3.Double-volute structure is used for pumps with high head, so that rotor components are subjected to low radial force and small shaft deflection.

4.The pump suction is along the axial line, and the discharge is in parallel with the axial line.

5.The shaft at the driving end is supported by a rolling bearing in the bearing housing, and the rolling bearing is grease lubricated.

6.The built-in sliding bearings in the pump are lubricated by the liquid conveyed.

7.During operation, the liquid level must be above the impeller centerline, and the impeller is immersed in the medium, without emptying.

8.The pump is comprised of body, cover, impeller, shaft, coupling, intermediate connection pipe, discharge pipe, bearing support and base plate.

9.The vertical motor of the pump drives the pump directly via an elastic coupling, and the whole pump is mounted on the vessel via a base plate.

10. Pump can run at high pressure,the maximum working pressure is 4.0Mpa.
