1. Axial Force Generation le Balancing Principles

The axial forces inmultistage  lipompo tsa turbine tse otlolohileng  haholo-holo li entsoe ka likarolo tse peli:

● Karolo ea matla a Centrifugal:Phallo ea radial ea metsi ka lebaka la matla a centrifugal e baka phapang pakeng tsa likoahelo tse ka pele le tse ka morao tsa impeller, e leng se bakang matla a axial (hangata a lebisitsoe ho sekeno sa ho hula).

● Phello e fapaneng ea khatello:Phapang ea khatello ea cumulative ho pholletsa le mohato ka mong e eketsa matla a axial.

Mekhoa ea ho leka-lekanya:

● Ho hlophisoa ha li-impeller:Ho sebelisa li-impeller tse peli (mokelikeli o kenang mahlakoreng ka bobeli) o fokotsa phapang ea khatello e sa lekanyetsoang, ho theola matla a axial ho maemo a amohelehang (10% -30%).

● Moralo oa lesoba le leka-lekaneng:Masoba a marang-rang kapa a oblique sekoahelong sa impeller se khutlisetsa mokelikeli o phahameng oa khatello ho khutlela koung, ho leka-lekanya phapang ea khatello. Boholo ba lesoba bo tlameha ho ntlafatsoa ka lipalo tsa fluid dynamics ho qoba tahlehelo ea ts'ebetso.

● Moralo oa blade o ka morao:Ho kenyelletsa li-blades tse ka morao (ho fapana le li-blades tse kholo) sethaleng sa ho qetela ho hlahisa matla a counter-centrifugal ho fokotsa meroalo ea axial. Hangata e sebelisoa lipompong tsa hlooho e phahameng (mohlala, multistage verticalturbinepumps).

2. Radial Load Generation le Balancing

Meroalo ea mahlaseli e tsoa ho matla a inertia nakong ea ho potoloha, kabo e sa lekanang ea khatello ea metsi a matla, le ho se leka-lekane ha boima ba rotor. Meroalo e bokelletsoeng ea radial lipompong tse nang le mekhahlelo e mengata e ka baka ho chesa ho feteletseng, ho sisinyeha kapa ho se tsamaisane hantle ha rotor.

Maano a ho leka-lekanya:

● Impeller symmetry optimization:

o Odd-even blade matching (mohlala, 5 blades + 7 blades) e aba matla a radial ka ho lekana.

o Dynamic balancing e etsa bonnete ba hore centroid e 'ngoe le e 'ngoe e ikamahanya le axis e potolohang, ho fokotsa ho se leka-lekane ho setseng.

● Matlafatso ea meralo:

o Mehaho e thata ea mahareng e thibelang ho falla ha mahlaseli.

o Li-bearings tse kopantsoeng (mohlala, li-bearings tse nang le mela e 'meli ea li-ball + cylindrical roller bearings) li tšoara meroalo ea axial le ea radial ka thoko.

● Matšeliso a Hydraulic:

o Tataisa li-vanes kapa likamore tse khutlisang ka har'a li-impeller clearances li ntlafatsa litsela tsa ho phalla, ho fokotsa maqhubu a sebaka le ho feto-fetoha ha matla a mahlaseli.

3. Phetiso ea Mojaro ho Li-Impellers tsa Multi-Stage

Mabotho a Axial a bokellana ho latela sethala mme a tlameha ho laoloa ho thibela khatello ea maikutlo:

● Ho leka-lekanya ho latela maemo:Ho kenya "balance disk" (mohlala, lipompong tsa centrifugal tse nang le mekhahlelo e mengata) ho sebelisa phapang ea khatello ea axial gap ho fetola matla a axial ka bo eona.

● Matlafatso ea ho satalla:Li-shafts tsa pompo li entsoe ka li-alloys tse matla a phahameng (mohlala, 42CrMo) 'me li netefalitsoe ka tlhahlobo ea lintlha tse fokolang (FEA) bakeng sa meeli ea ho kheloha (hangata ≤ 0.1 mm / m).

4. Thuto ea Taba ea Boenjiniere le Netefatso ea Palo

mohlala:Pompo ea turbine ea lik'hemik'hale tse ngata (mehato e 6, hlooho eohle 300 m, sekhahla sa phallo 200 m³/h):

● Palo ea matla a axial:

o Moqapi oa pele (mohaho o le mong): F=K⋅ρ⋅g⋅Q2⋅H (K=1.2−1.5), e hlahisang 1.8×106N.

o Ka mor'a ho sokolohela ho li-impeller tse peli tse monyang le ho eketsa likoti tse leka-lekaneng: Matla a Axial a fokotsehile ho 5 × 105N, ho kopana le litekanyetso tsa API 610 (≤1.5 × rated power torque).

● Ketsiso ea moroalo oa mahlaseli:

o ANSYS Fluent CFD e senotse litlhoro tsa khatello ea lehae (ho fihla ho 12 kN/m²) ka li-impellers tse sa ntlafatsoang. Ho hlahisa li-vane tsa tataiso li fokolitse litlhōrō ka 40% 'me mocheso o behang o nyoloha ka 15°C.

5. Lintlha tsa Moqapi oa Bohlokoa le Mehopolo

● Meeli ea matla a Axial: Ka tloaelo ≤ 30% ea matla a ho tsitsa a pompo ea shaft, e nang le mocheso oa mocheso oa ≤ 70 ° C.

● Taolo ea ho tlosa li-impeller: E bolokiloe pakeng tsa 0.2-0.5 mm (e nyenyane haholo e baka khohlano; e kholo haholo e lebisa ho lutla).

● Tlhahlobo e matla: Liteko tsa ho leka-lekanya ka lebelo le feletseng (G2.5 grade) li netefatsa botsitso ba tsamaiso pele ho ts'ebetso.

fihlela qeto e

Ho leka-lekanya meroalo ea axial le radial ka har'a lipompo tsa turbine tse otlolohileng ke phephetso e rarahaneng ea boenjiniere e kenyelletsang matla a mokelikeli, moralo oa mochini le mahlale a lintho tse bonahalang. Ho ntlafatsa jiometry ea impeller, ho kopanya lisebelisoa tsa ho leka-lekanya, le mekhoa e nepahetseng ea tlhahiso e matlafatsang haholo botšepehi ba pompo le nako ea bophelo. Tsoelo-pele ea nako e tlang ho lipapiso tsa lipalo tse tsamaisoang ke AI le tlhahiso ea tlatsetso e tla thusa ho ntlafatsa moralo oa motho ka mong le ho ntlafatsa mojaro o matla.

Tlhokomeliso: Moralo o ikhethileng bakeng sa lits'ebetso tse ikhethileng (mohlala, thepa ea mokelikeli, lebelo, mocheso) o tlameha ho tsamaellana le maemo a machabeng joalo ka API le ISO.
