1. Axial Force Generation uye Bancing Principles

The axial forces inmultistage  vertical turbine pombi  zvinonyanya kuumbwa nezvikamu zviviri:

● Centrifugal force component:Liquid radial inoyerera nekuda kwe centrifugal force inogadzira mutsauko wekumanikidza pakati pemberi nekumashure mavhavha eiyo impeller, zvichikonzera axial force (inowanzo kunanga kune inopinza yekudhonza).

● Pressure differential effect:Iyo cumulative pressure musiyano pane imwe neimwe nhanho inowedzera kuwedzera axial simba.

Kuenzanisa nzira:

● Symmetrical impeller marongero:Kushandisa kaviri-kusveta impellers (mvura inopinda kubva kumativi ose) inoderedza unidirectional pressure differential, kuderedza axial force kusvika kumazinga anogamuchirwa (10% -30%).

● Balance hole design:Radial kana oblique maburi mune impeller kumashure chivharo redirect high-pressure fluid kudzokera kunopinza, kuenzanisa kudzvanya misiyano. Saizi yegomba inofanirwa kugadziridzwa kuburikidza neiyo fluid dynamics kuverenga kudzivirira kurasikirwa kwekugona.

● Reverse blade design:Kuwedzera reverse blades (kupesana nemashizha makuru) muchikamu chekupedzisira kunogadzira simba re-counter-centrifugal kumisa axial mitoro. Inowanzoshandiswa mumapombi epamusoro-soro (semuenzaniso, multistage verticalturbinepumps).

2. Radial Load Generation uye Bancing

Radial mitoro inotangira kubva kune inertia masimba panguva yekutenderera, isina kuenzana yemvura ine simba yekumanikidza kugovera, uye yakasara kusaenzana muhuremu hwerotor. Yakaunganidzwa radial mitoro mumapombi-matanho akawanda anogona kukonzera kubereka kuwedzeredza, kuzunguzika, kana rotor misalignment.

Bancing Strategies:

● Impeller symmetry optimization:

o Odd-even blade matching (eg, 5 blades + 7 blades) inogovera radial masimba zvakaenzana.

o Dynamic balancing inova nechokwadi chekuti impeller's centroid inoenderana neaxis inotenderera, ichideredza kusaenzana kwasara.

● Kusimbiswa kwemaitiro:

o Dzimba dzakasimba dzepakati dzakabereka dzinorambidza kutamiswa kweradial.

o Akasanganiswa mabhengi (semuenzaniso, kaviri-mutsara anokanda bhora mabhengi + cylindrical roller bearings) kubata axial uye radial mitoro zvakasiyana.

● Muripo weHydraulic:

o Tungamira vanes kana makamuri ekudzoreredza mune impeller clearance inokwenenzvera nzira dzekuyerera, kuderedza mavhoti emunharaunda uye radial simba rekuchinja.

3. Mutoro wekutakura muMulti-Stage Impellers

Masimba eAxial anounganidza nhanho-akachenjera uye anofanirwa kudzorwa kudzivirira kushushikana mupfungwa:

● Stage-wise balancing:Kuisa dhisiki dhisiki (semuenzaniso, mune akawanda-nhanho centrifugal pombi) inoshandisa axial gap pressure misiyano kuti igadzirise otomatiki mauto axial.

● Kuomesa musoro:Pombi shafts inogadzirwa neakanyanya-simba alloys (semuenzaniso, 42CrMo) uye yakasimbiswa kuburikidza neinogumira chinhu chekuongorora (FEA) yekumisikidza miganhu (kazhinji ≤ 0.1 mm/m).

4. Engineering Case Study uye Calculation Verification

muenzaniso:Kemikari multistagevertical turbine pombi (matanho matanhatu, musoro wose 6 m, kuyerera 300 m³/h):

● Axial simba kuverenga:

o Magadzirirwo ekutanga (kamwe-kukweva impeller): F=K⋅ρ⋅g⋅Q2⋅H (K=1.2−1.5), zvichikonzera 1.8×106N.

o Mushure mekushandura kune kaviri-kusveta impeller uye kuwedzera maburi echiyero: Axial simba rakaderedzwa kusvika 5 × 105N, kusangana neAPI 610 zviyero (≤1.5 × yakayerwa simba torque).

● Radial load simulation:

o ANSYS Fluent CFD yakaratidza kudzvinyirirwa kwenzvimbo (kusvika ku12 kN/m²) mumapombi asina kunyatsogadziriswa. Kusuma madhiraivha ane mapikisi epamusoro ne40% uye anotakura tembiricha anokwira ne15°C.

5. Makiyi Magadzirirwo Akakosha uye Mafungiro

● Axial force limits: Kazhinji ≤ 30% yepombi shaft tensile simba, ine thrust inotakura tembiricha ≤ 70 ° C.

● Impeller clearance control: Yakachengetwa pakati pe 0.2-0.5 mm (kunyanya kuduku kunokonzeresa kukweshana; kunyanyokura kunotungamirira pakudonha).

● Kuedza kweDynamic: Yakazara-kumhanya kuenzanisa miedzo (G2.5 giredhi) inovimbisa kugadzikana kwehurongwa kusati kwaitwa.

mhedziso

Kuenzanisa axial uye radial mitoro mumultistage vertical turbine pombi idambudziko rakaoma sisitimu yeinjiniya inosanganisira simba remvura, dhizaini yekugadzira, uye sainzi yezvinhu. Kugonesa impeller geometry, kubatanidza kuenzanisa zvishandiso, uye chaiwo maitiro ekugadzira anowedzera zvakanyanya kuvimbika kwepombi uye hupenyu. Kufambira mberi mune ramangwana muAI-inotyairwa manhamba simulations uye yekuwedzera yekugadzira inozogonesa yakasarudzika impeller dhizaini uye ine simba mutoro optimization.

Ongorora: Dhizaini yakasarudzika yemashandisirwo chaiwo (semuenzaniso, zvivakwa zvemvura, kumhanya, tembiricha) inofanirwa kuenderana nemazinga epasi rese seAPI neISO.
