Kulinganiza mphamvu ya axial mu mapampu amtundu wa multistage centrifugal ndi ukadaulo wofunikira kwambiri kuti ugwire ntchito mokhazikika. Chifukwa cha mndandanda wa ma impellers, mphamvu za axial zimadziunjikira kwambiri (mpaka matani angapo). Ngati sizili bwino bwino, izi zitha kubweretsa kuchulukirachulukira, kuwonongeka kwa chisindikizo, kapena kulephera kwa zida. M'munsimu muli njira zofananira za axial mphamvu, pamodzi ndi mfundo zake, ubwino, ndi kuipa kwake.
1.Symmetrical Impeller Arrangement (Kubwerera-kumbuyo / Kuyang'ana-Kumaso)
Mu mapangidwe a axial mphamvu bwino chipangizo chamakono centrifugal mpope, siteji impeller zambiri amasankhidwa ngati nambala ngakhale, chifukwa pamene siteji impeller ndi chiwerengero, ndi chotengera symmetrical kugawa njira angagwiritsidwe ntchito kulinganiza mphamvu axial zida, ndi mphamvu ya axial kwaiye ndi symmetrically anagawira chophophonya mu njira magnide ndi kusonyeza njira ndi kusonyeza njira ndi magnide. mkhalidwe wofanana pamlingo wa macroscopic. Popanga mapangidwe, ziyenera kudziwidwa kuti kukula kwa kusindikiza kosindikiza kusanachitike kulowetsedwa kwa reverse impeller kumagwirizana ndi mainchesi a choyikapo kuti zitsimikizire kusindikiza bwino.
●Mfundo yofunika: Zoyimitsira zoyandikana zimakonzedwa mosiyanasiyana kuti mphamvu zawo za axial zithetserena.
●Kubwerera-kumbuyo: Ma seti awiri a ma impellers amayikidwa mozungulira mozungulira papa shaft midpoint.
●Maso ndi maso: Zotulutsa zimakonzedwa moyang'anizana mkati kapena kunja mumawonekedwe agalasi.
●Ubwino wake: Palibe zida zowonjezera zofunika; kapangidwe kosavuta; Kuchita bwino kwambiri (kuposa 90%).
●Zoipa: Mapangidwe a nyumba zapampu zovuta; zovuta kuyenda njira kukhathamiritsa; imagwira ntchito pamapampu okhala ndi magawo angapo.
●Mapulogalamu: Mapampu ophatikizira kwambiri, mapampu a petrochemical multistage.
2. Kulinganiza Drum
Dongosolo la ng'oma yabwino (yomwe imadziwikanso kuti pistoni yolinganiza) ilibe chilolezo cholimba cha axial, chomwe chingathe kulipira zambiri za axial thrust, koma osati zonse za axial thrust, ndipo palibe malipiro owonjezera pamene akuyenda mu malo axial, ndipo mayendedwe oyendetsa amafunika nthawi zambiri. Kapangidwe kameneka kadzakhala ndi kubwerezanso kwamkati (kutuluka kwamkati) koma kumalekerera kuyambika, kuzimitsa, ndi zina zosakhalitsa.
●Mfundo yofunika: Ng'oma ya cylindrical imayikidwa pambuyo pa siteji yotsiriza. Madzi othamanga kwambiri amalowa mumpata pakati pa ng'oma ndi casing kulowa m'chipinda chocheperako, kutulutsa mphamvu yolimbana nayo.
● Aubwino: Kuthekera kolimba kofananira, koyenera kuthamanga kwambiri, mapampu amitundu yambiri (mwachitsanzo, masitepe 10+).
●Zoipa: Kutaya kutaya (~ 3-5% ya kuchuluka kwa kuthamanga), kuchepetsa mphamvu. Pamafunika mapaipi owonjezera ofananira kapena makina obwereza, kukulitsa zovuta zokonza.
●Mapulogalamu: Mapampu akuluakulu apakati pa masitepe ambiri (monga mapampu a mtunda wautali).
3.Balance Disk
Monga wamba kamangidwe njira mu kamangidwe ka axial mphamvu bwino chipangizo chamakono multistage centrifugal mpope, ndi bwino chimbale njira akhoza amtengo kusintha malinga ndi kufunika kupanga, ndi mphamvu mphamvu makamaka kwaiye ndi gawo mtanda pakati pa radial chilolezo ndi axial chilolezo cha litayamba, ndi mbali ina makamaka kwaiye ndi axial chimbale chilolezo ndi mbali mbali ziwiri za chigawo mphamvu ya masewero a disc disc disc disc discerance ndi mbali ziwiri za gawo la masewero a masewero. kugwirizanitsa mphamvu ya axial. Poyerekeza ndi njira zina, ubwino wa njira yoyenera mbale ndi kuti m'mimba mwake wa mbale bwino ndi zazikulu ndi tilinazo ndi apamwamba, amene bwino bwino ntchito bata la chipangizo chipangizo. Komabe, chifukwa chachilolezo chaching'ono cha axial, kapangidwe kameneka kamatha kuvala ndikuwonongeka pakanthawi kochepa.
●Mfundo yofunika: Diski yosunthika imayikidwa pambuyo pa chowongolera chomaliza. Kusiyanitsa kwapanikizidwe kudutsa diski kumasintha mosintha malo ake kuti athane ndi mphamvu ya axial.
●Ubwino wake: Zimangosintha zokha ku kusintha kwa mphamvu ya axial; kulinganiza kwakukulu.
●Zoipa: Kukangana kumayambitsa kutha, kumafuna kusinthidwa pafupipafupi. Zomverera ndi ukhondo wamadzimadzi (tinthu tating'onoting'ono titha kupanikizana pa disk).
●Mapulogalamu: Mapampu amadzi aukhondo oyambilira masitepe ambiri (pang’ono ndi pang’ono amasinthidwa ndi ng’oma zolinganiza).
4.Kuphatikiza Drum + Disk Combination
Poyerekeza ndi njira yoyendetsera mbale, njira ya ng'oma ya balance plate ndi yosiyana chifukwa kukula kwa gawo lake la throttle bushing ndilokulirapo kuposa kukula kwa chiwongolero, pomwe chimbale chowongolera chimafuna kukula kwa throttle bushing kuti chifanane ndi kukula kwa chowongolera. Nthawi zambiri, mu kamangidwe njira ya mbale mbale ng'oma, mphamvu bwino kwaiye ndi bwino mbale nkhani zoposa theka la okwana axial mphamvu, ndi pazipita akhoza kufika 90% ya okwana axial mphamvu, ndi mbali zina makamaka anapereka ndi ng'oma bwino. Pa nthawi yomweyo, amtengo kuonjezera bwino mphamvu ya bwino ng'oma adzakhala n'chimodzimodzi kuchepetsa bwino mphamvu ya mbale bwino, ndipo mofanana kuchepetsa kukula kwa mbale bwino, potero kuchepetsa avale mlingo wa mbale bwino, kuwongolera moyo utumiki wa mbali zida, ndi kuonetsetsa ntchito yachibadwa ya multistage centrifugal mpope.
●Mfundo yofunika: Ng'oma imayendetsa mphamvu zambiri za axial, pamene diski imapanga bwino mphamvu yotsalira.
●Ubwino wake: Zimaphatikiza kukhazikika ndi kusinthika, koyenera kusinthasintha kwa magwiridwe antchito.
●Zoipa: Mapangidwe ovuta; mtengo wapamwamba.
●Mapulogalamu: Pampu zamafakitale zogwira ntchito kwambiri (mwachitsanzo, mapampu ozizirira nyukiliya).
5. Ma thrust Bearings (Axiliary Balancing)
●Mfundo yofunika: Mipira yolumikizana ndi angular kapena mayendedwe a Kingsbury amatenga mphamvu yotsalira ya axial.
●Ubwino wake: Kusunga zodalirika panjira zina zofananira.
●Zoipa: Imafunika kuthira mafuta pafupipafupi; moyo wautali pansi pa katundu wa axial wapamwamba.
●Mapulogalamu: Mapampu ang'onoang'ono mpaka apakatikati ambiri kapena mapampu othamanga kwambiri.
6. Kapangidwe ka Double-Suction Impeller
●Mfundo yofunika: Chotsitsa choyamwa kawiri chimagwiritsidwa ntchito pa siteji yoyamba kapena yapakatikati, kulinganiza mphamvu ya axial kupyolera m'mbali ziwiri zolowera.
●Ubwino wake: Kuyang'ana mogwira mtima ndikuwongolera magwiridwe antchito a cavitation.
●Zoipa: Amangoyezera mphamvu imodzi yokha ya axial; njira zina zimafunika papampu multistage.
7. Mabowo a Hydraulic Balance (Mabowo a Impeller Backplate)
●Mfundo yofunika: Mabowo amabowoleredwa mu impeller backplate, kulola kuti madzi othamanga kwambiri abwererenso kumalo otsika kwambiri, kuchepetsa mphamvu ya axial.
●Ubwino wake: Zosavuta komanso zotsika mtengo.
●Zoipa: Amachepetsa mphamvu ya mpope (~ 2-4%).Oyenera okha ntchito otsika axial mphamvu; nthawi zambiri zimafuna mayendedwe owonjezera.
