1. I-Axial Force Generation kanye Nezimiso Zokulinganisa

Amandla e-axial ku-multistage  amaphampu ophephela mpo  zakhiwe ngokuyinhloko izingxenye ezimbili:

● Ingxenye ye-Centrifugal force:Ukugeleza kwe-radial okuwuketshezi ngenxa yamandla aphakathi nendawo kudala umehluko wengcindezi phakathi kwekhava yangaphambili nangemuva ye-impeller, okuholela kumandla e-axial (ngokuvamile aqondiswe endaweni yokudonsa).

● Umphumela ohlukile wengcindezi:Umehluko wengcindezi eqoqwayo esigabeni ngasinye unyusa futhi amandla e-axial.

Izindlela zokulinganisa:

● Ukuhlelwa kwe-Symmetrical impeller:Ukusebenzisa ama-impellers adonsa kabili (uketshezi lungena lusuka ezinhlangothini zombili) kunciphisa ukuhluka kokucindezela okukodwa, kwehlisa amandla e-axial kumazinga amukelekayo (10% -30%).

● Idizayini yembobo yebhalansi:Izimbobo ezikhanyayo noma ezitshekile kukhava ye-impeller engemuva ziqondisa kabusha uketshezi olunomfutho ophezulu lubuyele endaweni yokungena, ibhalansisa umehluko wengcindezi. Usayizi wembobo kufanele uthuthukiswe ngezibalo ze-fluid dynamics ukuze kugwenywe ukulahlekelwa ukusebenza kahle.

● Idizayini ye-blade ehlehlayo:Ukwengeza ama-blade ahlehlayo (okuphambene nama-blade amakhulu) esigabeni sokugcina kukhiqiza amandla aphikisana ne-centrifugal ukuze asuse imithwalo ye-axial. Okuvame ukusetshenziswa kumaphampu anekhanda eliphezulu (isb., amaphampu e-multistage verticalturbinepump).

2. Isizukulwane Somthwalo We-Radial kanye Nokulinganisa

Imithwalo yeradial isuka kumandla we-inertia ngesikhathi sokuzungezisa, ukusabalalisa kwengcindezi yoketshezi eguquguqukayo engalingani, nokungalingani okusele kusisindo se-rotor. Imithwalo enqwabelene yama-radial kumaphampu anezigaba eziningi ingabangela ukuthwala ukushisa, ukudlidliza, noma ukungahambi kahle kwe-rotor.

Amasu okulinganisa:

● Ukuthuthukisa i-impeller symmetry:

o Ukumadanisa kwe-Odd-even blade (isb, izindwani ezi-5 + izindwani eziyi-7) kusabalalisa amandla eradial ngokulinganayo.

o Ukulinganisa okunamandla kuqinisekisa ukuthi i-centroid ye-impeller ngayinye iqondana ne-axis ejikelezayo, kunciphisa ukungalingani kwensalela.

● Ukuqiniswa kwesakhiwo:

o Izindlu eziqinile eziphakathi nendawo zikhawulela ukususwa kwe-radial.

o Ama-bearings ahlanganisiwe (isb, ama-double-row thrust ball bearings + cylindrical roller bearings) asingatha imithwalo ye-axial ne-radial ngokuhlukana.

● Isinxephezelo samanzi:

o Qondisa ama-vanes noma amagumbi okubuyisela ezindaweni zokususa i-impeller engeza izindlela zokugeleza, wehlise ama-vortices endawo kanye nokuguquguquka kwamandla e-radial.

3. Ukudluliswa komthwalo kuma-Multi-Stage Impellers

Amandla e-Axial aqongelela esiteji futhi kufanele alawulwe ukuvimbela ukugxila kwengcindezi:

● Ukulinganisa okuhlakaniphile kwesiteji:Ukufaka idiski yebhalansi (isb, kumaphampu we-centrifugal ezigaba eziningi) kusebenzisa umehluko we-axial gap pressure ukulungisa ngokuzenzakalelayo amandla e-axial.

● Ukuthuthukisa ukuqina:Amaphampu amashafu enziwe ngama-alloy anamandla aphezulu (isb, 42CrMo) futhi aqinisekiswa ngokuhlaziywa kwesici esilinganiselwe (FEA) ngemikhawulo yokuchezuka (imvamisa engu-≤ 0.1 mm/m).

4. Indaba Yobunjiniyela kanye Nokuqinisekisa Ukubala

Isibonelo:Iphampu ye-multistagevertical turbine yamakhemikhali (izigaba eziyisi-6, ingqikithi yekhanda elingu-300 m, izinga lokugeleza elingu-200 m³/h):

● Ukubalwa kwamandla e-axial:

o Idizayini yokuqala (i-impeller yokudonsa okukodwa): F=K⋅ρ⋅g⋅Q2⋅H (K=1.2−1.5), okuholela ku-1.8×106N.

o Ngemva kokuguqulela ku-impeller yokumunca kabili nokwengeza izimbobo zebhalansi: Amandla e-Axial ancishisiwe abe ngu-5 × 105N, ahlangabezana namazinga we-API 610 (≤1.5× i-torque yamandla elinganiselwe).

● Ukulingisa ukulayishwa kwe-radial:

o I-ANSYS I-Fluent CFD iveze iziqongo zengcindezi yendawo (efika ku-12 kN/m²) kuma-impellers angalungiswanga. Ukwethula ama-vane omhlahlandlela anciphise iziqongo ngo-40% futhi athwale izinga lokushisa likhuphuke ngo-15°C.

5. Imibandela Yokuklama Ebalulekile Nokucatshangelwa

● Imikhawulo yamandla e-Axial: Ngokuvamile ≤ 30% wamandla okunyakazisa we-pump shaft, enezinga lokushisa elithwala i-thrust ≤ 70°C.

● Ukulawula ukukhishwa kwe-impeller: Kugcinwe phakathi kuka-0.2-0.5 mm (okuncane kakhulu kubangela ukungqubuzana; okukhulu kakhulu kuholela ekuvuzeni).

● Ukuhlola okunamandla: Ukuhlolwa kokulinganisa isivinini esigcwele (ibanga le-G2.5) kuqinisekisa ukuzinza kwesistimu ngaphambi kokusebenza.

Isiphetho

Ukulinganisa imithwalo ye-axial kanye ne-radial kumaphampu e-turbine eqondile e-multistage kuyinselelo eyinkimbinkimbi yobunjiniyela bezinhlelo ehlanganisa ukuguquguquka koketshezi, ukwakheka kwemishini, nesayensi yezinto ezibonakalayo. Ukuthuthukisa i-impeller geometry, ukuhlanganisa amadivaysi okulinganisa, kanye nezinqubo zokukhiqiza ezinembayo kuthuthukisa kakhulu ukuthembeka kwepompo nempilo yokuphila. Intuthuko yesikhathi esizayo ekufanisweni kwezinombolo okushayelwa yi-AI kanye nokukhiqiza okungeziwe kuzophinde kunikeze amandla ukwakheka komuntu siqu kwe-impeller kanye nokwenza kahle komthwalo oguqukayo.

Qaphela: Idizayini eyenziwe ngokwezifiso yezinhlelo zokusebenza ezithile (isb, izakhiwo eziwuketshezi, isivinini, izinga lokushisa) kufanele ihambisane nezindinganiso zamazwe ngamazwe njenge-API ne-ISO.
