Iphampu ehlukanisayo yesiteji esisodwa/ekabili(API610/BB2)

1. Umzimba wephampu: Umzimba wephampu wamukela isakhiwo segumbi lokuskrola kabili ukuze unciphise amandla e-radial, ukunciphisa umthwalo we-shaft, futhi andise impilo yesevisi yama-bearings; ukufakwa kwe-centerline kanye nezakhiwo zokusekela kuzo zombili iziphetho zingathuthukisa ukusebenza kwepompo ngenxa yokukhuphuka kwezinga lokushisa ngaphansi kwezimo zokushisa eziphezulu. Ukuphakama kungase kubangele ukwanda nokuguqulwa komzimba wepompo; indawo yokungena nokuphuma komzimba wephampu ingalungiswa ngezindlela ezihlukahlukene ukuze kube lula ukuhlelwa kwepayipi lomsebenzisi;

2. Isembozo sephampu: Isembozo sepompo sinomklamo oqinile, umthamo oqinile wokuthwala ingcindezi, nokuthembeka okuphezulu. I-gasket yensimbi enokwethenjelwa kakhulu isetshenziselwa ukuvala umzimba wepompo kanye nesembozo sepompo, okwenza kube lula ukuthutha imidiya ephezulu, enobuthi, eyingozi futhi ehwamuke kalula;

3. I-Impeller: Isakhiwo sesiteji esisodwa ngokuvamile sisebenzisa i-impeller edonsa kabili ukunciphisa i-NPSH yepompo futhi yehlise izindleko zokufakwa kwedivayisi. Ngesikhathi esifanayo, i-double-suction impeller ingakwazi ukulinganisa amandla e-axial akhiqizwa ngokwawo: isakhiwo esinezigaba ezimbili ngokuvamile sisebenzisa isigaba sokuqala sokudonsa kabili kanye ne-impeller yesigaba sesibili. Isiteji sokuqala sokudonsa okukodwa kanye nesigaba sokuqala sokudonsa kabili singacabangela izidingo ze-cavitation zepompo. I-impeller yesibili isebenzisa imbobo yebhalansi ukuze ilinganise ukucindezela kwe-axial, futhi amandla asele e-axial aphethwe yi-bearing. Ngezimo zokusebenza ezinezidingo eziphansi ekusebenzeni kwe-cavitation kanye nokusebenza kahle okuphezulu, isakhiwo se-single-suction back-to-back noma ubuso nobuso singacatshangelwa;

4. I-Shaft: Yamukela umklamo we-shaft oqinile onokuphambuka okuncane. Uma ububanzi be-shaft bukhulu kune-60mm, yakhelwe njengesandiso se-shaft conical, esiza ukufakwa nokuhlakazeka kokuhlanganisa, ama-bearings kanye nezimpawu;

5. Ama-Bearings and Lubrication: Ama-bearings asebenzisa ama-oil-ring self-lubricating rolling bearings noma ama-sliding bearing structures ngokusho kwamandla e-shaft kanye nesivinini. Lapho kukhethwa isakhiwo esinamabhola aginqikayo, isiphetho sokushayela sisebenzisa i-deep groove ball bearing ukuze sinikeze ukusekela kwe-radial, futhi isiphetho esingashayeki sifakwe ipheya yama-angular amabhola okuxhumana ukuze kukhawulwe ukunyakaza kwe-axial ye-rotor futhi ngesikhathi esifanayo kunikeze i-radial. ukwesekwa; lapho kusetshenziswa i-bearing bearing, ama-radial sliding bearings emikhawulweni yomibili adlala indima yokusekela i-radial, futhi ama-angular amabhola okuxhumana ahlelwa ngemuva kwe-radial bear ekugcineni okungashayeli ukukhawulela ukunyakaza kwe-axial ye-rotor;

6. Umakhenikha uphawu: Uhlelo lokuvala luhambisana nezidingo ze-API682 4th Edition "Centrifugal Pump kanye neRotary Pump Sealing System" kanye namazinga okuthengwa kwempahla ye-Sinopec, futhi ingacushwa ngezinhlobo ezahlukene zokuvala, ukushaywa, kanye nezisombululo zokupholisa.
