Umehluko phakathi kwephampu ye-centrifugal yesiteji esisodwa kanye ne-multistage centrifugal pump

Amaphampu e-Centrifugal abalulekile ezinhlelweni ezihlukene zezimboni nezohwebo, futhi ukukhetha uhlobo olufanele kungaba nomthelela omkhulu ekusebenzeni nokusebenza kahle. Phakathi kwezinhlobo ezivame kakhulu kukhonaiphampu ye-centrifugal yesiteji esisodwafuthiiphampu ye-centrifugal enezigaba eziningi. Nakuba zombili ziklanyelwe ukudlulisa uketshezi, zihluka kakhulu ekwakhekeni kwazo kanye nezici zokusebenza. Ukuqonda lo mehluko kubalulekile ekukhetheni iphampu efanele izidingo zakho.

1.Umthamo Wekhanda Ophakeme

Omunye wemehluko oyinhloko phakathi kwephampu ye-centrifugal yesiteji esisodwa kanye namaphampu amaphakathi esiteji esiningi amandla awo aphezulu ekhanda.
Iphampu ye-centrifugal yesiteji esisodwa, njengoba negama liphakamisa, ifaka isigaba se-impeller esisodwa kuphela. Zenzelwe ukuphatha amandla ekhanda afinyelela cishe kumamitha ayi-125. Lokhu kuwenza afanelekele izinhlelo zokusebenza lapho ubude obudingekayo bokumpompa bunesizotha uma kuqhathaniswa, njengasezinhlelweni zokunikezwa kwamanzi ezinomfutho ophansi noma izinqubo zezimboni ezinezidingo zokuphakama eziqondile ezilinganiselwe.
Ngokuphambene, i-multistage centrifugal pump ifakwe ama-impeller amaningi ahlelwe ngochungechunge. Lokhu kumiswa kuzivumela ukuthi zifinyelele amandla ekhanda aphezulu kakhulu, ngokuvamile adlula amamitha angu-125. Isiteji ngasinye sinikela ekhanda eliphelele, okwenza lawa maphampu akwazi ukuphatha izinhlelo zokusebenza ezinzima lapho kudingeka khona ukuphakamisa okuqondile okubalulekile. Isibonelo, amaphampu ezigaba eziningi avame ukusetshenziswa ezinhlelweni zokuphakelwa kwamanzi ezakhiweni eziphakeme, ukumpompa imithombo ejulile, nezinye izimo lapho kudingeka khona ingcindezi enkulu ukuze kunqotshwe izinselele zokuphakama.

2.Inani Lezigaba

Inombolo yezigaba empompini ithinta ngokuqondile amandla ayo okusebenza. Iphampu yesiteji esisodwa se-centrifugal iqukethe i-impeller eyodwa kanye ne-volute casing. Lo mklamo uqondile futhi uyasebenza ekuphatheni izinhlelo zokusebenza ezinezidingo zekhanda elilinganiselwe. Ubulula bephampu ye-centrifugal yesiteji esisodwa kuvame ukuhumusha ekwehliseni izindleko zokuqala kanye nezidingo ezincishisiwe zokunakekela.
Ngakolunye uhlangothi, iphampu yesiteji esiningi ihlanganisa ama-impeller amaningi, ngalinye lingaphakathi kwesigaba salo. Lezi zigaba ezengeziwe ziyadingeka ukuze kukhiqizwe izingcindezi eziphezulu ezidingekayo ezicelweni ezifuna kakhulu. Izigaba zihlelwa ngokulandelana, nge-impeller ngayinye ikhuphula ukucindezela okukhiqizwa yilowo odlule. Nakuba lokhu kuphumela ekwakhiweni okuyinkimbinkimbi, kuthuthukisa kakhulu ikhono lephampu lokufinyelela izingcindezi eziphezulu kanye nokusingatha izimo eziyinselele.

3. I-Impeller Quantity

Omunye umehluko obalulekile phakathi kwesiteji esisodwa kanye nepompo ye-multistage yinombolo yama-impellers.
Iphampu yesiteji esisodwa esiyi-centrifugal ine-impeller eyodwa eshayela uketshezi ngepompo. Lokhu kulungiselelwa kulungele izinhlelo zokusebenza ezinezidingo eziphansi zekhanda, lapho i-impeller eyodwa ingakwazi ukuphatha ngokuphumelelayo ukugeleza kwamanzi nokucindezela.
Ngokuphambene, iphampu yesiteji esiningi ifakwe ama-impeller amabili noma ngaphezulu. I-impeller ngayinye inyusa ingcindezi yoketshezi njengoba idlula iphampu, ngomphumela okhulayo oholela kumthamo wekhanda jikelele. Isibonelo, uma iphampu ye-centrifugal yesiteji esisodwa isetshenziselwa izinhlelo zokusebenza ezidinga inhloko yamamitha angu-125 noma ngaphansi, iphampu yesiteji esiningi ingaba inketho ekhethwayo yanoma yiluphi uhlelo lokusebenza oludlula lobu bude.

Iyiphi engcono?

Lokhu kunqunywa ikakhulukazi izidingo zokusetshenziswa zangempela. Ngokuya ngobude bekhanda, khetha iphampu edonsa kabili noma iphampu yezigaba eziningi. Ukusebenza kahle kwephampu yamanzi eyi-centrifugal yezigaba eziningi kungaphansi kwalokho kwephampu ye-centrifugal yesiteji esisodwa. Uma zombili isiteji esisodwa kanye namaphampu esiteji esiningi zingasetshenziswa, ukukhetha kokuqala yiphampu yesiteji esisodwa esiyi-centrifugal. Uma isiteji esisodwa kanye nepompo yokumunca kabili kungahlangabezana nezidingo, zama ukusebenzisa iphampu yesiteji eyodwa. Amaphampu e-Multistage anesakhiwo esiyinkimbinkimbi, izingxenye eziningi ezisele, izidingo zokufakwa okuphezulu, futhi kunzima ukuzigcina.
