1. Axial Force Generation and Bancing Principles

The axial Force inmultistage  nfuli turbine kwụ ọtọ  bụ isi ihe mejupụtara abụọ mejupụtara:

● Akụkụ ike nke Centrifugal:Mmiri radial na-asọpụta n'ihi ike centrifugal na-eme ka nrụgide dị iche n'etiti mkpuchi ihu na azụ nke impeller, na-ebute ike axial (na-edugakarị na ntinye mmiri).

● Mmetụta dị iche iche nrụgide:Mkpokọta nrụgide dị iche n'ofe ọ bụla na-abawanye ike axial.

Ụzọ nhazi:

● Nhazi impeller Symmetrical:Iji okpukpu abụọ na-amịpụta mmiri (mmiri na-abanye n'akụkụ abụọ) na-ebelata ihe dị iche iche nrụgide unidirectional, na-ebelata ike axial na ọkwa a na-anabata (10%-30%).

● Nhazi oghere:Oghere radial ma ọ bụ oblique dị na mkpuchi azụ impeller redirect mmiri mmiri dị elu laghachi na ntinye, na-edozi esemokwu nrụgide. A ga-emerịrị nha oghere site na ngụkọ ngbanwe nke mmiri iji zere mfu arụmọrụ.

● Ntughari agụba:Ịtinye agụba azụ (nke dị n'akụkụ isi agụba) na ọkwa ikpeazụ na-ebute ike counter-centrifugal iji kwụsị ibu axial. A na-ejikarị nfuli isi elu (dịka ọmụmaatụ, multistage verticalturbinepumps).

2. Radial Load Generation na Balance

Ibu radial sitere na ike inertia n'oge ntụgharị, nkesa mmiri na-adịghị agbanwe agbanwe, yana enweghị ahaghị nhata na oke rotor. Ibu radial ekpokọbara na nfuli ọtụtụ ọkwa nwere ike ime ka oke ekpo oke ọkụ, ịma jijiji, ma ọ bụ nhazi rotor.

Atụmatụ nhazi:

● Nkwalite symmetry impeller:

o Odd-ọbụna agụba dakọtara (dịka ọmụmaatụ, agụba 5 + agụba 7) na-ekesa ike radial n'otu n'otu.

o Ntuzi di omimi na-eme ka centroid impeller nke ọ bụla kwekọọ na axis ntụgharị, na-ebelata ahaghị nhata.

● Nkwado ihe owuwu:

o Ụlọ ndị dị n'etiti ndị siri ike na-amachibido nchụpụ radial.

o Ngwakọta bearings (eg, okpukpu abụọ n'ahịrị atụgharị bọọlụ + cylindrical roller bearings) na-ejikwa ibu axial na radial iche iche.

● Ụgwọ hydraulic:

o Nduzi vanes ma ọ bụ ọnụ ụlọ nlọghachi na nkwụsị nke impeller na-ebuli ụzọ eruba, na-ebelata vortices mpaghara na mgbanwe ike radial.

3. Ibu Ibu nnyefe na Multi-Stage impellers

Ndị agha axial na-agbakọta ọkwa-amamihe ma a ga-ejikwa ya gbochie mkpokọta nchekasị:

● Ndozi n'ụzọ amamihe dị na ọkwa:Ịwụnye diski nguzozi (dịka ọmụmaatụ, na nfuli centrifugal multi-stage) na-eji ọdịiche nrụgide axial gap dozie ike axial ozugbo.

● Nkwalite isi ike:A na-eji ihe alloys dị elu mee ihe mgbapụta mgbapụta (dịka, 42CrMo) ma kwado ya site na nyocha nke njedebe (FEA) maka oke ngbanwe (na-abụkarị ≤ 0.1 mm / m).

4. Ọmụmụ ihe gbasara injinia na nkwenye mgbako

Ihe Nlereanya:Igwe mmiri na-agbapụta turbine multistagevertical kemịkalụ (nkeji 6, ngụkọta isi 300 m, ọnụego erute 200 m³/h):

● Mgbakọ ike axial:

o Nhazi mmalite (mkpọpụta otu-amịpụta): F=K⋅ρ⋅g⋅Q2⋅H (K=1.2−1.5), na-ebute 1.8×106N.

o Mgbe n'ịtụgharị na abụọ-suction impeller na-agbakwụnye itule oghere: Axial ike belatara 5 × 105N, izute API 610 ụkpụrụ (≤1.5 × gosiri ike torque).

● Simulation radial:

o ANSYS Fluent CFD ekpughere oke nrụgide mpaghara (ruo 12 kN/m²) n'ime ihe ndị na-enweghị ike. Ịwebata vanes nduzi belatara ọnụ ọgụgụ kasị elu site na 40% yana ibuli elu okpomọkụ site na 15 Celsius.

5. Isi Ikike Nhazi na echiche

● Oke ike axial: A na-ahụkarị ≤ 30% nke ike mgbapụta mgbapụta mgbapụta, na-ebuli okpomọkụ ≤ 70 ° C.

● Njikwa mkpochapụ impeller: Na-edobe n'etiti 0.2-0.5 mm (obere obere na-akpata esemokwu; oke buru ibu na-eduga na ntapu).

● Nnwale dị egwu: Nnwale nhazi ngwa ngwa zuru oke (G2.5 grade) hụ na nkwụsi ike nke usoro tupu ịnye ọrụ.

mmechi

Idozi ibu axial na radial inmultistage vetikal turbine nfuli bụ ihe ịma aka nke sistemu dị mgbagwoju anya gụnyere mgbanwe mmiri, imepụta igwe, na sayensị ihe. Na-ebuli geometry impeller, ijikọ ngwaọrụ na-edozi ahụ, yana usoro nrụpụta ziri ezi na-akwalite ntụkwasị obi mgbapụta na ogologo ndụ. Ọganihu n'ọdịniihu na ịme anwansị ọnụọgụgụ AI na-ebute na mmepụta mgbakwunye ga-eme ka imewe impeller ahaziri onwe ya na njikarịcha ibu dị ike.

Mara: Nhazi ahaziri maka ngwa akọwapụtara (dịka ọmụmaatụ, akụrụngwa mmiri, ọsọ, okpomọkụ) ga-agbasorịrị ụkpụrụ mba ụwa dịka API na ISO.
