本产品适宜输送不含固体颗粒的易燃、易爆、有毒、有害及贵重介质和其他要求无泄漏及介质不允许密封材料污染的场合。

除非能有效排除铁磁性微粒，否则本产品应避免输送含有铁磁性物料的液体。

CQB Magnetic Driven Centrifugal Pump is a magnetic driven single-stage single-suction centrifugal pump, a new type magnetic driven chemical process pump, designed to ISO2858 standard. This product is designed to convey inflammable and explosive, toxic, harmful and rare valuable fluids in the petrochemical process. It has the distinctive features of full-enclosure, leakage free, contamination free, low vibration and noise, an ideal environmental-friendly product in petrochemical, fine chemical, metallurgical, power, paper-making, pharmaceutical and foodstuff industries.

This product is suitable for conveying inflammable and explosive, toxic, harmful and valuable media containing no solid particles and in other applications requiring no leakage, and no contamination of sealing materials by media.

Unless ferrous magnetic particles can be effectively removed, conveying liquid containing ferrous magnetic material with this product should be avoided.

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。全密封，无泄漏。

2.采用ISO2858标准，方便替代IH型、ZA型和CZ型化工流程泵。

3.工艺液体自冷却润滑传动部件，不需要额外管路系统。

4.整台泵只需1～2个密封圈，确保了运行安全。

5.优化的刚性轴结构设计，具有更佳的挠度指数，使泵的振动值进一步降低。

6.泵的轴向力主要靠叶轮上的副叶片或者平衡孔进行水力平衡，残余轴向力由推力轴承承受。

7.采用大厚度、重载、强推力陶瓷轴承，选用高纯度、高耐磨性的碳化硅材料，使用寿命长。

8.内外磁转子均为全密封式结构，防止泵在腐蚀环境下磁体腐蚀和磁性能的衰退。

9.泵体具有底脚支撑和中心支撑（CQBH）两种形式，供不同温度介质时选用，基本型采用底脚支撑、低温与高温型采用中心支撑。

10.新型的诱导轮技术，可使泵的必需汽蚀余量更低。

11.多种循环方式将泵内产生的涡流热和摩擦热带走，以满足不同介质的输送。典型的循环系统有：

a.内循环式。通过泵内液体压力差形成自循环。

b.外循环式。当不宜使用泵送介质进行自润滑冷却时，可引入外来液体，但外来液体必须高于泵腔内的压力0.07～0.1MPa。

12.一般无需额外的冷却循环系统。

13.因结晶、汽化等工况需要时，可带冷却或保温夹套。

14.可选择电机直连或通过联轴器连接的形式。

15.从驱动端看，泵为顺时针方向旋转。

16.法兰标准可提供ANSI、HG/T20615、HG/T20592等多种选择。

17.可配带普通Y系列电机、YB系列防爆型电机、直流电机和永磁电机等。

1.This pump is of horizontal single stage and single suction type with radial split, axial suction and radial discharge. It is fully enclosed and leakage free.

2.It is based on ISO2858 standard, and can be conveniently used in place of type IH, ZA and CZ chemical process pumps.

3.The driving parts are cooled and lubricated by process liquid, without additional piping system.

4.In the whole pump, only 1~2 sealing rings are used, ensuring operation safety.

5.Optimized rigid shaft structure design with better deflection index has further reduced the vibration of the pump.

6.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 on the thrust bearing.

7.Ceramic bearings of big thickness, heavy duty and high thrust are used, and they are made with high purity and high wear resisting carborundum material, with a long service life.

8.Both internal and external magnetic rotors are in fully enclosed structure, to prevent corrosion of magnetic mass and attenuation of magnetic property with the pump in corrosive environments.

9.Pump body is available in two types: foot support and center support, for use with media of different temperature; the basic model is provided with foot support and low and high temperature types with center support.

10.New type inducer technology is adopted, to further reduce the necessary NPSH of the pump.

11.The heat produced by eddy current and friction in the pump is carried away with a number of circulation forms, to allow conveying different media. Typical circulation systems include:

a. Internal circulation. Self-circulation is formed by the liquid differential pressure within the pump.

b. External circulation. When self-lubrication and cooling with pumped media is not suitable, external liquid can be connected, provided that the incoming liquid pressure must be 0.07~0.1MPa above the pressure within the pump cavity.

12.Normally additional cooling circulation system is not required.

13.Cooling or insulation jacket can be provided when required in conditions such as crystallization and gasification.

14.Either direct driving by motor or via coupling can be used.

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

16.A number of options for flanges to standards ANSI, HG/T20615 and HG/T20592.    

17.It can be provided with general-purpose Y series motor, YB series explosion-proof motor, DC motor and permanent magnetic motor.
