結(jié)構(gòu)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(huán)和平衡孔，以平衡軸向力；
5.通過泵送工藝液體自循環(huán)和外接液體強(qiáng)制循環(huán)等多種循環(huán)方式將泵內(nèi)產(chǎn)生的渦流熱和摩擦熱帶走，以滿足不同工況介質(zhì)的輸送。
6.設(shè)置有冷卻或保溫夾套。
7.優(yōu)化的剛性軸結(jié)構(gòu)設(shè)計(jì)，具有更佳的撓度指數(shù)，使泵的振動(dòng)值進(jìn)一步降低。
8.內(nèi)置滑動(dòng)軸承采用了大厚度、重載、強(qiáng)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(nèi)外磁轉(zhuǎn)子均為全密封式結(jié)構(gòu)，防止泵在腐蝕環(huán)境下磁體腐蝕和磁性能的衰退。
10.滾動(dòng)軸承采用稀油潤滑，其油位由油標(biāo)和油杯同時(shí)控制，油杯能自動(dòng)補(bǔ)償油位；
11.采用了加長撓性膜片式聯(lián)軸器部件，檢修時(shí)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(jù)工況條件進(jìn)行冷卻，冷卻水的管路布置符合API682規(guī)范。
13.泵和電機(jī)安裝在同一個(gè)公用底座上。
14.法蘭標(biāo)準(zhǔn)可提供ANSI、HG/T20615、HG/T20592等多種選擇。
15.可配帶普通電機(jī)、防爆電機(jī)、直流電機(jī)和永磁電機(jī)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.
