Kuenzanisa axial simba mumapombi akawanda ecentrifugal tekinoroji yakakosha kuti ive nechokwadi chekushanda kwakagadzikana. Nekuda kweakatevedzana marongero ezvipombi, axial mauto anounganidza zvakanyanya (kusvika kune akati wandei matani). Kana zvisina kuenzana zvakanaka, izvi zvinogona kutungamira mukuremerwa, kukuvadzwa kwechisimbiso, kana kunyange kutadza kwemidziyo. Pazasi pane akajairwa axial simba kuenzanisa nzira, pamwe nemisimboti yavo, zvakanakira, uye zvazvakaipira.
1.Symmetrical Impeller Arrangement (Kumashure-kumashure / Kutarisana-kutarisana)
Mukugadzirwa kweaxial force balance device yemazuva ano centrifugal pombi, impeller stage inowanzosarudzwa senhamba yakaenzana, nokuti kana impeller stage iri even number, impeller symmetrical distribution nzira inogona kushandiswa kuenzanisa simba reaxial remudziyo, uye simba re axial rinogadzirwa ne symmetrically distributed impeller mu magnide inotarisana mukuita magnide uye nzira yekushanda. equilibrium state pane macroscopic level. Muchigadziro chekugadzira, zvinofanirwa kucherechedzwa kuti iyo yekuisa chisimbiso throttling saizi pamberi pekupinza kweiyo reverse impeller inopindirana nedhayamita yeimpeller kuti ive nechokwadi chekuisa chisimbiso.
●Principle: Mapombi ari pedyo akarongwa mumativi akasiyana kuitira kuti axial mauto adzingane kunze.
●Kudzokera-kumashure: Maseti maviri emaimpeller akaiswa symmetrically kutenderedza pombi shaft midpoint.
●Vakatarisana: Impellers dzakarongwa dzakatarisana nechomukati kana kunze mumirrored configuration.
●Zvakanakira: Hapana mimwe michina inodiwa; chimiro chiri nyore; kukwirira kwekuenzanisa (kupfuura 90%).
●Zvakaipa: Complex pombi dzimba dhizaini; yakaoma kuyerera nzira optimization; inongoshanda kumapombi ane kunyange nhamba yematanho.
●Applications: Yakakwira-kudzvanya boiler feed pombi, petrochemical multistage pombi.
2. Kuenzanisa Drum
Iyo yekuenzanisa dhiramu chimiro (inozivikanwawo seyekuenzanisa piston) haina yakasimba axial inomhanya clearance, iyo inogona kutsiva yakawanda yeaxial thrust, asi kwete yese yeaxial thrust, uye hapana muripo wekuwedzera kana uchifamba munzvimbo yeaxial, uye mabhengi ekusundira anowanzo kudiwa. Iyi dhizaini ichave nepamusoro yemukati recirculation (yemukati kuvuza) asi inoshivirira yekutanga-ups, shutdown, uye mamwe mamiriro echinguvana.
●Principle: A cylindrical drum inoiswa mushure mekupedzisira-danho impeller. Mvura ine simba guru inopinda nemumukana uri pakati pedhiramu uye casing ichipinda mukamuri ine simba rakaderera, ichigadzira simba rinopikisa.
● Azvakanakira: Yakasimba kuenzanisa kugona, yakakodzera kune yakakwirira-kumanikidza, mapombi akawanda (semuenzaniso, 10+ nhanho).
●Zvakaipa: Kurasikirwa kwekudonha (~ 3-5% yehuwandu hwekuyerera), kuderedza kushanda. Inoda mamwe mapombi ekuyera kana masisitimu ekudzokorora, kuwedzera kuoma kwekugadzirisa.
●Applications: Mapombi makuru e centrifugal (eg, pombi dzemapaipi akareba).
3.Kuenzanisa Disk
Seyakajairwa dhizaini nzira mukugadzira dhizaini yeaxial simba rekuenzanisa mudziyo wemazuva ano multistage centrifugal pombi, iyo bharanzi disc nzira inogona kugadziridzwa zvine mwero zvichienderana nekugadzirwa kwechido, uye chiyero chesimba rinonyanya kugadzirwa nemuchinjiko-chikamu pakati peiyo radial clearance uye axial clearance ye dhisiki, uye chimwe chikamu chinonyanya kugadzirwa neaxial dhizaini dhizaini uye maviri ekutamba dhisiki chikamu uye maviri ekutamba dhisiki kuenzanisa simba reaxial. Kana ichienzaniswa nedzimwe nzira, mukana weiyo nzira yekuyeresa yeplateti ndeyekuti dhayamita yeplateti yechiyero yakakura uye kunzwisiswa kwakakwira, izvo zvinonyatso kuvandudza kugadzikana kwekushanda kwechigadzirwa chemidziyo. Nekudaro, nekuda kweiyo diki axial inomhanya clearance, dhizaini iyi inogona kupfeka uye kukuvara pasi pemamiriro enguva pfupi.
●Principle: Dhisiki inofambiswa inoiswa mushure mekupedzisira-danho impeller. Musiyano wekumanikidza mukati me diski zvine simba unogadzirisa chinzvimbo chayo kurwisa axial simba.
●Zvakanakira: Inogadzirisa otomatiki kune axial simba kusiyana; high balancing precision.
●Zvakaipa: Friction inokonzeresa kupera, inoda kuchinjwa nguva nenguva. Inonzwa kuchena kwemvura (zvimedu zvinogona jam disk).
●Applications: Pombi dzemvura dzakachena dzekutanga-nhanho dzakawanda (zvishoma nezvishoma dzinotsiviwa nemadhiramu ekudzikamisa).
4.Kuenzanisa Drum + Disk Combination
Kana ichienzaniswa neiyo balance plate nzira, iyo balance plate dhiramu nzira yakasiyana pakuti saizi ye throttle bushing part yakakura kudarika saizi ye impeller hub, nepo balance disc inoda saizi ye throttle bushing kuti ienderane nehukuru hwe impeller hub. Kazhinji kutaura, mumaitiro ekugadzira dhiramu rebalance plate, simba rekuyeresa rinogadzirwa nebharanzi plate account inodarika hafu yeaxial force yese, uye iyo yakakwira inogona kusvika 90% yesimba rose reaxial, uye zvimwe zvikamu zvinonyanya kupihwa nedhiramu yekuenzanisa. Panguva imwecheteyo, kuwedzera zvine mwero simba rekuyeresa yedhiramu yedhiramu ichaita zvinoenderana nekuderedza simba rechiyero chendiro yekuyeresa, uye nenzira imwecheteyo kuderedza saizi yendiro yekuyeresa, nekudaro ichidzikisa dhigirii rekupfeka rendiro, kuvandudza hupenyu hwesevhisi yezvikamu zvemidziyo, uye kuve nechokwadi chekushanda kwakajairika kwepombi ye centrifugal yakawanda.
●Principle: Ngoma inobata yakawanda yeaxial simba, nepo dhisiki inogadzirisa simba rinosara.
●Zvakanakira: Inobatanidza kugadzikana uye kugadzikana, yakakodzera kune zvakasiyana-siyana zvekushanda.
●Zvakaipa: Complex chimiro; mutengo wakakwirira.
●Applications: Mapombi emuindasitiri anoshanda zvakanyanya (semuenzaniso, nuclear reactor inotonhorera pombi).
5. Thrust Bearings (Axiliary Balancing)
●Principle: Angular yekubata bhora mabearings kana Kingsbury mabheji anotora residual axial simba.
●Zvakanakira: Yakavimbika backup kune dzimwe nzira dzekuenzanisa.
●Zvakaipa: Inoda kugara uchizora; hupenyu hupfupi pasi pemitoro yakakwira axial.
●Applications: Diki-kusvika-yepakati multistage pombi kana yakakwirira-kumhanya pombi.
6. Kaviri-Suction Impeller Design
●Principle: A kaviri-kusveta impeller inoshandiswa padanho rekutanga kana repakati, kuenzanisa axial simba kuburikidza nehuviri-kurutivi kunopinda.
●Zvakanakira: Kushanda kuenzanisa paunenge uchivandudza cavitation performance.
●Zvakaipa: Chete chiyero chimwe-nhanho axial simba; dzimwe nzira dzinodiwa pamapombi akawanda.
7. Hydraulic Balance Holes (Impeller Backplate Holes)
●Principle: Makomba anodonhedzwa mu impeller backplate, achibvumira high-pressure fluid kutenderera kune yakaderera-pressure zone, kuderedza axial simba.
●Zvakanakira: Nyore uye yakaderera-mutengo.
●Zvakaipa: Inoderedza kushanda kwepombi (~ 2-4%).Chete yakakodzera kune yakaderera axial simba zvikumbiro; kazhinji inoda maturusi ekuwedzera.
