I-SOF/SOU High suction pressure pump (API610/OH2)

Iphampu yenqubo ye-petrochemical yochungechunge lwe-OH2 iyiphampu evundlile, yesiteji esisodwa, ehlukaniseke ngemisebe ye-cantilever centrifugal. Lolu chungechunge lwamaphampu lunebhokisi elithwala elihlukile ukuze lithwale wonke amandla asetshenziswa ku-pump shaft futhi liqinisekise isikhundla se-rotor. Ipompo ifakwe Esisekelweni futhi ixhunywe kumshayeli wayo ngokuhlanganisa okuguquguqukayo.

1. Umzimba wephampu: Umzimba wephampu wamukela idizayini yesakhiwo esiyivolute. I-pump body outlet ≥DN80 isebenzisa idizayini ye-hydraulic eyivolumu ephindwe kabili, elinganisela amandla eradial ngezinga elikhulu kakhulu. Usayizi we-flange orifice uklanywe ngokuhambisana nezidingo ze-API610. Umzimba wephampu Ukwesekwa kwe-centerline kungathuthukisa ukuzinza kokushisa futhi imelane nomthwalo ophezulu we-nozzle. I-drainage interface yomzimba wepompo i-welded futhi ihlanganiswe ngokuphelele;

2. Izingxenye zokuthwala: Izingxenye zokuthwala (ibhokisi eliphethe, i-bearing, shaft, indlala, ikhava yepompo, njll.) zamukela umklamo jikelele wokudonsa ngaphandle, ovumela ukuhlolwa nokugcinwa kwepompo ngaphandle kokunyakazisa amapayipi okungenisa nokuphuma. Izingxenye ezithwalayo zisebenzisa umklamo oqinile, futhi akukho ubakaki ophethe ekugcineni kwebhokisi elithwalayo;

3. I-Shaft: I-shaft iyisakhiwo se-shaft engenalutho, futhi inkomba yokuqina ye-pump shaft ihlangabezana nezidingo ze-API61011 Appendix K. Ngesikhathi esifanayo, isakhiwo se-impeller nut anti-reverse siyamukelwa ukuze kuhlangatshezwane nezidingo zesayithi. izimo zokusebenza kanye nokwenza ngcono ukuphepha nokuzinza kwemishini.

4. Ibhalansi yamandla e-axial: Izindandatho ezikwazi ukumelana nokugqoka zenzelwe izinhlangothi zombili ze-impeller, futhi imbobo yebhalansi ivuliwe ngaphakathi ukuze yenze ingcindezi ezinhlangothini zombili ze-impeller self-balance, futhi i-thrust bear ithwala kuphela okuphansi. umthwalo.

5. Ama-bearings kanye nokuthambisa: I-bearing yangaphambili (i-bearing eduze kwekhanda lepompo) isebenzisa ama-deep groove ball bearings, athwala amandla e-radial kuphela. I-bearing yangemuva (i-bearing eseduze nomkhawulo wokushayela) isebenzisa ama-angular amabhola okuxhumana (uchungechunge lwama-73) noma ama-roller bearings ama-tapered (31 series); ama-bearings amukela isakhiwo sokugcoba indandatho kawoyela, futhi uphawu lohlobo lwe-isolator oluthwele lungakhethwa ngokuya ngezidingo zomsebenzisi Noma uphawu lwe-labyrinth.

6. Mechanical seal: Usayizi womgodi wokuvala uhambisana ne-API682 4th "Shaft Seal System for Centrifugal Pump and Rotary Pumps", futhi kungalungiswa izinhlobo ezahlukene zokuvala, zokushaywa umoya, kanye nezisombululo zokupholisa.
