Iindlela zokulinganisa iAxial kunye neRadial Load Balancing kwiiPumpu zeTurbine eziNqobileyo ezininzi.
1. I-Axial Force Generation kunye neMithetho-siseko yokulinganisa
Amandla e-axial kwiqonga elikhulu iimpompo zeinjini ezithe nkqo ikakhulu zenziwe ngamacandelo amabini:
● Icandelo lamandla e-Centrifugal:Ukuqukuqela kweradial yolwelo ngenxa yamandla asecentrifugal kudala umahluko woxinzelelo phakathi kwezigqubuthelo zangaphambili nasemva ze-impeller, okukhokelela kumandla e-axial (ngokuqhelekileyo ajoliswe kwindawo yokufunxa).
● Isiphumo soxinzelelo loxinzelelo:Umahluko woxinzelelo olongezelekayo kwisigaba ngasinye unyusa ngakumbi amandla e-axial.
Iindlela zokulinganisa:
● Ulungelelwaniso lwe-impeller elinganayo:Ukusebenzisa ii-impellers zokufunxa kabini (ulwelo lungena kumacala omabini) lunciphisa ukwahlukana koxinzelelo lwe-unidirectional, ukuthoba amandla e-axial kumanqanaba amkelekileyo (10% -30%).
● uyilo lomngxuma wokulinganisa:Imingxunya yeRadial okanye e-oblique kwi-impeller back cover iphinda iqondise ulwelo olunoxinzelelo oluphezulu emva kwindawo yokungena, ukulinganisa umahluko woxinzelelo. Ubungakanani bomngxuma kufuneka buphuculwe ngokusebenzisa izibalo ze-fluid dynamics ukuthintela ilahleko yokusebenza kakuhle.
● Uyilo lweblade umva:Ukongeza iiblades ezibuyela umva (ngokuchasene neencakuba eziphambili) kwinqanaba lokugqibela livelisa amandla okumelana ne-centrifugal ukuphelisa imithwalo ye-axial. Ngokuqhelekileyo zisetyenziswa kwiimpompo eziphezulu zentloko (umz., i-multistage verticalturbinepumps).
2. UkuVeliswa koMlayisho weRadi kunye nokuLinganisa
Imithwalo yeradial isuka kumandla e-inertia ngexesha lokujikeleza, ulwelo olungalinganiyo lokusasazwa koxinzelelo oluguquguqukayo, kunye nokungalingani okushiyekileyo kubunzima berotor. Imithwalo ye-radial eqokelelweyo kwiimpompo zamanqanaba amaninzi inokubangela ukuthwala ukushisa, ukungcangcazela, okanye ukungahambi kakuhle kwe-rotor.
Ulungelelwaniso lwezicwangciso:
● I-Impeller symmetry optimizations:
o Ukuthelekisa iincakuba ezi-Odd-even (umzekelo, iiblade ezi-5 + 7 iincakuba) zisasaza amandla eradial ngokulinganayo.
o Ukulinganisa okuguquguqukayo kuqinisekisa i-centroid ye-impeller nganye ihambelana ne-axis ejikelezayo, ukunciphisa ukungalingani okushiyekileyo.
● Ukomelezwa kolwakhiwo:
o Ulwakhiwo lwezindlu oluqinileyo oluphakathi lunqanda ukufuduswa kweradial.
o Iibheringi ezidityanisiweyo (umz., iibheringi zebhola ezikuluhlu oluphindwe kabini + iibheringi eziqengqelekayo ezisilinda) zibamba imithwalo yeaxial kunye neradial ngokwahlukeneyo.
● Imbuyekezo ye-hydraulic:
o Isikhokelo se-vanes okanye amagumbi abuyiswayo kwi-impeller clearances akhulisa iindlela zokuhamba, ukunciphisa i-vortices yendawo kunye nokuguquguquka kwamandla emitha.
3. Ukuhanjiswa komthwalo kwii-Multi-Stage Impellers
Amandla e-Axial aqokelelana ngokwenqanaba kwaye kufuneka alawulwe ukunqanda ukugxilwa koxinzelelo:
● Ukulungelelanisa ngokwenqanaba:Ukufakela i-balance disk (umzekelo, kwi-multi-stage centrifugal pumps) isebenzisa i-axial gap umahluko woxinzelelo ukuze ulungelelanise ngokuzenzekelayo amandla e-axial.
● Ukomelela kokuqina:I-pump shafts yenziwe ngama-alloys aphezulu (umzekelo, i-42CrMo) kwaye iqinisekisiwe ngokuhlalutya kwezinto ezinqamlekileyo (FEA) kwimida yokuphambuka (ngokuqhelekileyo ≤ 0.1 mm / m).
4. Uphononongo lobuNjineli kunye noQinisekiso lokubala
Umzekelo:Impompo yeinjini yeikhemikhali yamanqanaba amaninzi (izigaba ezi-6, intloko iyonke yi-300 m, isantya sokuhamba ngama-200 m³/h):
● Ukubalwa kwamandla e-axial:
o Uyilo lokuqala (i-impeller yokufunxa enye): F=K⋅ρ⋅g⋅Q2⋅H (K=1.2−1.5), ekhokelela ku-1.8×106N.
o Emva kokuguqulwa kwi-double-suction impeller kunye nokongeza imingxuma yokulinganisa: Amandla e-Axial ancitshiswe kwi-5 × 105N, ukuhlangabezana nemigangatho ye-API 610 (≤1.5 × i-torque yamandla elinganisiweyo).
● Ukulinganisa umthwalo weradial:
o I-ANSYS I-Fluent CFD iveze iincopho zoxinzelelo lwasekhaya (ukuya kuthi ga kwi-12 kN/m²) kwizithinteli ezingalungiswanga. Ukwazisa i-vanes yesikhokelo icuthe iincopho ngama-40% kwaye ithwala ubushushu bunyuke nge-15°C.
5. Iikhrayitheriya zoYilo oluPhambili kunye neNgqwalasela
● Imida yamandla e-Axial: Ngokuqhelekileyo ≤ 30% yamandla e-pump shaft tensile, kunye ne-thrust ethwele ukushisa ≤ 70 ° C.
● Ulawulo lwe-impeller clearance: Igcinwe phakathi kwe-0.2-0.5 mm (incinci kakhulu ibangela ukukhuhlane; inkulu kakhulu ikhokelela ekuvuzeni).
● Uvavanyo olunamandla: Iimvavanyo zokulinganisa isantya esipheleleyo (i-G2.5 grade) ziqinisekisa ukuzinza kwenkqubo ngaphambi kokugunyaziswa.
isiphelo
Ukulinganisa imithwalo ye-axial kunye ne-radial kwiimpompo ze-injini ye-injini ethe nkqo ngumngeni wobunjineli weenkqubo ezibandakanya amandla olwelo, uyilo lomatshini, kunye nesayensi yezinto eziphathekayo. Ukuphucula ijometri ye-impeller, ukudibanisa izixhobo zokulinganisa, kunye neenkqubo zokwenziwa ezichanekileyo zokuphucula kakhulu ukuthembeka kwempompo kunye nobomi. Inkqubela phambili yexesha elizayo kulinganiso lwamanani oluqhutywa yi-AI kunye nokuveliswa okongeziweyo kuya kunceda ngakumbi uyilo lwe-impeller eyenzelwe wena kunye nokwandisa umthwalo oguqukayo.
Qaphela: Uyilo olulungiselelwe usetyenziso oluthile (umzekelo, iimpawu zolwelo, isantya, ubushushu) kufuneka luhambelane nemigangatho yamazwe ngamazwe efana ne-API kunye ne-ISO.
