CQE型泵为单级单吸卧式磁力驱动石油化工流程泵,该型泵参照美国石油学会API685及其相关标准设计制造,具有全密封、无泄漏、无污染,效率高,汽蚀性能好、零部件通用性、互换性好,结构安全可靠,运转稳定等特点,可广泛应用于石油化工、精细化工、冶金、电力等行业。

CQE型泵通过内外磁转子进行耦合传动,隔离套将内磁转子密封在泵腔内,运用磁力驱动技术,解决了石油化工流程中易燃易爆、有毒有害及稀有贵重流体的输送问题。

本产品适宜输送清洁或稍有污染且不含固体颗粒的介质。

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。

CQE pump is a single stage, single suction horizontal magnetic drive petrochemical process pump. It has been designed and manufactured by referencing API685 and other relevant standards. It features full sealing, no leakage, no pollution, high reliability, good cavitation performance, good versatility and interchangeability of parts, high structural safety and reliability, and stable operation etc. It can be widely used for petrochemical industry, fine chemical industry, metallurgy, and electric power industry etc.

CQE pump is driven by coupled internal and external magnetic rotors. An isolation sleeve seals the internal magnetic rotor inside the pump cavity. Magnetic drive technology has been used, solving the difficult problem of conveying inflammable, explosive, toxic, harmful, rare, and noble fluids in petrochemical flow path.

This product is applicable to conveying clean or slightly contaminated media not containing solid particles.

Except ferromagnetic particles can be effectively removed, use of this product to convey liquid containing ferromagnetic material shall be avoided.

 

结构说明 Description of structure

1.该系列泵均为单级、单吸、卧式悬臂离心泵;

2.泵为轴向水平吸入,径向垂直排出;

3.泵体为蜗壳式、径向剖分,水平中心支撑;

4.叶轮为整体铸造,带有后密封环和平衡孔,以平衡轴向力;

5.通过泵送工艺液体自循环和外接液体强制循环等多种循环方式将泵内产生的涡流热和摩擦热带走,以满足不同工况介质的输送。

6. 因结晶、汽化等工况需要时,可带冷却或保温夹套。

7.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。

8.内置滑动轴承采用了大厚度、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。

9.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。

10.滚动轴承采用稀油润滑,其油位由油标和油杯同时控制,油杯能自动补偿油位;

11.采用了加长挠性膜片式联轴器部件,检修时不必拆卸吸入和吐出管路就能拆出叶轮、轴等零部件;

12.对轴承、泵支架,根据工况条件进行冷却,冷却水的管路布置符合API682规范。

13.泵和电机安装在同一个公用底座上。

14.法兰标准可提供ANSIHG/T20615HG/T20592等多种选择。

15.可配带普通电机、防爆电机、直流电机和永磁电机等。

1. This series pumps are all single stage, single suction, horizontal cantilever centrifugal pumps.

2. These pumps adopt axial horizontal suction and radial vertical discharge.

3. Pump body adopts volute type, radial splitting, and horizontal central support.

4. The impeller is an integral casting, complete with rear seal ring and balance hole to balance axial force.

5. Eddy flow heat and friction heat generated in the pump is taken away by various circulation modes, e.g. pumped process liquid self-circulation and forced circulation of externally connected liquid, to satisfy conveying of media under different operating conditions.

6. Cooling or thermal insulation jacket can be provided if required by operating condition such as crystallization or evaporation.

7. Optimized rigid shaft structural design provides better deflection index, further reducing pump vibration.

8. Internal sliding bearing adopts thick, heavy duty, strong thrust ceramic bearing, and high purity, high wear resistance silicon carbide material, thus allowing long service life.

9. Both internal and external magnetic rotors adopt fully sealed structure, thus preventing pump magnet corrosion in corrosive environment and deterioration of magnetism.

10. Roller bearing is lubricated by oil, with the oil level controlled by both oil gauge and oil cup. This oil cup can automatically compensate the oil level.

11. Lengthened flexible membrane type coupling is adopted. For maintenance, parts such as impeller and shaft etc. can be removed without dismantling the suction pipeline or discharge pipeline.

12. Bearing and pump supports are cooled according to operating condition, with cooling water pipeline layout meeting API682 code.

13. The pump and the motor are installed on the same pedestal.

14. Flange standard may be ANSI, HG/T20615, or HG/T20592.

15. ordinary motor, explosionproof motor, DC motor, or permanent magnet motor etc. can be used.
