DRE型磁力驱动导热油泵
DRE Magnetic Driven Heat Transfer Oil Pump

DRE型系列泵，参照美国石油学会API685及其相关标准设计制造，全密封、无泄漏。专用于高温热油加热场合或类似的热媒环境，选用具有较高的磁能积和极低的温度系数，温度稳定性和化学稳定性高的磁性材料，可输送温度至400℃的热传送流体，是一种理想的高温热油循环泵。
该产品也可用于输送低温流体，应用于恒低温场合和易结晶流体的输送。
DRE pumps are specially designed for applications with high temperature hot oil heating or similar thermal media environment; they are made with magnetic materials with high magnetic energy product and extremely low temperature coefficient, and high temperature and chemical stability, to transfer heat transfer fluid with temperature up to 400℃, hence an ideal high temperature heat transfer oil circulating pump.
The product can also be used to transfer low temperature fluid, in applications of constant low temperature and conveying fluid likely to crystallize.
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.设置有冷却或保温夹套。
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ANSI、HG/T20615、HG/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.
