CQF氟塑料磁力驱动离心泵，是新型磁力驱动氟塑料衬里离心泵，采用国际标准ISO2858设计，过流部件采用氟塑料衬里，全密封无泄漏，适用于石油、化工、冶金、电力、造纸等工业部门。

本产品适宜输送强腐蚀性介质。除熔融碱金属，发烟硝酸等少数介质外，选用不同的氟塑料材料，几乎能抵抗所有化学介质的腐蚀，包括浓硝酸和王水的腐蚀。

CQF fluoroplastic magnetic driven centrifugal pump is a new type magnetic driven fluoroplastic lined centrifugal pump, designed to international standard ISO2858.The flow passage components are lined with fluoroplastic, and the pumpis fully enclosed and leakage free, suitable in industrial sectors such as petroleum, chemicals, metallurgy, power and paper-making.

This product is suitable for conveying highly corrosive media. Except for a small number of media such as molten alkali metal and fuming nitric acid, with different fluoroplastics, it can resist the corrosion of all chemical media, including concentrated nitric acid and aqua regia.

结构说明 Description of structure

1.该型泵为单级、单吸、卧式、径向剖分，轴向吸入、径向排出。

2.泵的轴向力主要靠叶轮上的副叶片进行水力平衡，残余轴向力由推力轴承承受。

3.采用ISO2858标准，方便替代IHF化工泵。

4.工艺液体自冷却润滑传动部件。

5.整台泵只需要1-2个密封圈，全密封，无泄漏，确保了安全性。

6.过流部件采用氟塑料内衬，尤其是PFA，其析出的污染物最少，非常适用于输送高纯度的化学药液。

7.泵轴由高强度的无压烧结碳化硅制成，滑动轴承由高密度碳型碳化硅材料制成。

8.一般采用叶轮与内磁转子分体式结构，优于普遍的叶轮与内磁转子一体式结构，降低了意外情况下的故障损失，减少了备件损耗。

9.选用不锈钢、碳钢、球墨铸铁等不同材质的外壳体，增加了泵在各种介质温度的强度及耐腐蚀性能。

10.选用纤维增强罩保护的隔离套，既消除了涡流损失，又获得了足够的强度，提高了隔离套的承压能力。

11.可选择电机直连或通过联轴器连接的形式，电机直连式了节省成本和空间，传动效率高，安装方便，不需要同心度较准。

12.从驱动端看，泵为顺时针方向旋转。

13. 该型号泵可以采用立式结构，型号标记为CQFL。

1. This pump is of horizontal single stage and single suction type with radial split, axial suction and radial discharge.

2.The axial load on the pump is mainly balanced hydraulically by the back blades or balance holes on the impeller, and the residual axial force is taken by the thrust bearing.

3.ISO2858 standard is adopted in place of IHF chemical pumps conveniently.

4.The driving components are cooled and lubricated by process liquid.

5.In the whole pump, only 1~2 sealing rings are used, ensuring best safety performance with total enclosing and free of leakage.

6.Flow passage parts are lined with fluoroplastics, especially PFA, with minimum pollutant separated out, highly suitable for conveying high purity chemical liquid.

7.The pump shaft is made with high strength pressureless sintered carborundum, and sliding bearings are made with high density carbon type carborundum.

8.The impeller and inner magnetic rotor are normally in split structure, which is better than the ordinary integrated structure for impeller and inner rotor, reducing the failure loss in case of accident and lowering spare parts consumption.

9. External volute is available in different materials such as stainless steel, carbon steel and modular cast iron, increasing the strength and corrosion resistance of the pump at all media temperature.

10.Spacers protected by fiber-reinforced hood are used, eliminating eddy current loss and obtaining sufficient strength, with increased pressure bearing capacity of spacer.

11.Either direct connection or via coupling can be selected for motor, and direct connection of motor saves cost and space, featuring high driving efficiency and convenient installation, without the need of concentricity alignment.

12.The pump rotates in a clockwise direction when viewed from the driving end.

13. Pumps of this model can adopt vertical structure. The model marking is CQFL.
