DRE型磁力驅動導熱油泵
DRE Magnetic Driven Heat Transfer Oil Pump

DRE型系列泵，參照美國石油學會API685及其相關標準設計制造，全密封、無泄漏。專用于高溫熱油加熱場合或類似的熱媒環境，選用具有較高的磁能積和極低的溫度系數，溫度穩定性和化學穩定性高的磁性材料，可輸送溫度至400℃的熱傳送流體，是一種理想的高溫熱油循環泵。
該產品也可用于輸送低溫流體，應用于恒低溫場合和易結晶流體的輸送。
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.
結構說明  Description of structure
1.該系列泵均為單級、單吸、臥式懸臂離心泵；
2.泵為軸向水平吸入，徑向垂直排出；
3.泵體為蝸殼式、徑向剖分，水平中心支撐；
4.葉輪為整體鑄造，帶有后密封環和平衡孔，以平衡軸向力；
5.通過泵送工藝液體自循環和外接液體強制循環等多種循環方式將泵內產生的渦流熱和摩擦熱帶走，以滿足不同工況介質的輸送。
6.設置有冷卻或保溫夾套。
7.優化的剛性軸結構設計，具有更佳的撓度指數，使泵的振動值進一步降低。
8.內置滑動軸承采用了大厚度、重載、強推力陶瓷軸承，選用高純度、高耐磨性的碳化硅材料，使用壽命長。
9.內外磁轉子均為全密封式結構，防止泵在腐蝕環境下磁體腐蝕和磁性能的衰退。
10.滾動軸承采用稀油潤滑，其油位由油標和油杯同時控制，油杯能自動補償油位；
11.采用了加長撓性膜片式聯軸器部件，檢修時不必拆卸吸入和吐出管路就能拆出葉輪、軸等零部件；
12.對軸承、泵支架，根據工況條件進行冷卻，冷卻水的管路布置符合API682規范。
13.泵和電機安裝在同一個公用底座上。
14.法蘭標準可提供ANSI、HG/T20615、HG/T20592等多種選擇。
15.可配帶普通電機、防爆電機、直流電機和永磁電機等。
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.
