I-axial icala lokuhlukanisa amaphampu asetshenziswa kabanzi ekwelapheni amanzi, embonini yamakhemikhali, ukuchelela ngenkasa kwezolimo neminye imikhakha. Umsebenzi wabo oyinhloko ukuthutha uketshezi ukusuka endaweni eyodwa kuya kwenye. Kodwa-ke, lapho iphampu imunca amanzi, ububanzi bayo bokudonsa ngokuvamile bukhawulelwe kumamitha amahlanu kuya kwayisithupha, okuye kwaphakamisa imibuzo phakathi kwabasebenzisi abaningi. Lesi sihloko sizohlola izizathu zokukhawulwa kwebanga lokumunca iphampu kanye nezimiso zomzimba ezingemuva kwalo.

Ngaphambi kokuxoxa, kufanele siqale sicacise ukuthi ububanzi bokudonsa kwepompo akuyona inhloko. Umehluko phakathi kwalokhu okubili umi kanje:

1.Ibanga lokudonsa

Incazelo: Ibanga lokumunca libhekisela ekuphakameni lapho iphampu ikwazi ukumunca khona uketshezi, okungukuthi, ibanga eliqondile ukusuka endaweni ewuketshezi ukuya endaweni yokungena yepompo. Ngokuvamile kubhekisela ekuphakameni okuphezulu lapho iphampu ingakwazi ukumunca kahle amanzi ngaphansi kwezimo zengcindezi engalungile.

Izici ezinomthelela: Ububanzi bokumunca buthintwa izici ezifana nomfutho womoya, ukucindezelwa kwegesi empompini, kanye nomfutho womoya woketshezi. Ngaphansi kwezimo ezijwayelekile, ububanzi bokudonsa obusebenzayo bephampu ngokuvamile buba ngamamitha angu-5 ukuya kwangu-6.

2.Ikhanda

Incazelo: Ikhanda libhekisela ekuphakameni okuthiiphampu yecala lokuhlukaniswa kwe-axialingakhiqiza ngoketshezi, okungukuthi, ubude lapho iphampu ingaphakamisa khona uketshezi isuka endaweni yokungena iye endaweni yokuphuma. Ikhanda alihlanganisi nje kuphela ukuphakama kwephampu, kodwa nezinye izici ezifana nokulahlekelwa ukungqubuzana kwamapayipi nokulahlekelwa ukumelana nendawo.

Izici ezithonyayo: Ikhanda lithintwa ijika lokusebenza kwepompo, izinga lokugeleza, ukuminyana kanye ne-viscosity yoketshezi, ubude nobubanzi bepayipi, njll. Ikhanda libonisa amandla okusebenza ephampu ngaphansi kwezimo ezithile zokusebenza.

Umgomo oyisisekelo wepompo ye-axial split case ukusebenzisa amandla aphakathi nendawo akhiqizwe umfutho ozungezayo ukushayela ukugeleza koketshezi. Lapho i-impeller ijikeleza, uketshezi lumuncwa ku-inlet yepompo, bese uketshezi luyasheshiswa futhi luphushwe ngaphandle kokuphuma kwepompo ngokujikeleza kwe-impeller. Ukudonsa kwephampu kufinyelelwa ngokuncika ekucindezelweni komkhathi kanye nomehluko ophansi wengcindezi empompini. Umehluko ku-atmospheric pressure uzophinde uthinte:

Umkhawulo Wengcindezi Yomoya

Uhla lokumunca lwephampu luthintwa ngokuqondile ukucindezela komkhathi. Ezingeni lolwandle, umfutho womoya ojwayelekile ungama-101.3 kPa (760 mmHg), okusho ukuthi ngaphansi kwezimo ezikahle, ububanzi bokudonsa bephampu ngokwethiyori lungafinyelela cishe kumamitha angu-10.3. Nokho, ngenxa yokulahlekelwa ukungqubuzana oketshezini, amandla adonsela phansi nezinye izici, ububanzi bangempela bokumunca ngokuvamile bukhawulelwe kumamitha angu-5 ukuya kwangu-6.

Ukucindezelwa kwegesi kanye neVacuum

Njengoba ububanzi bokudonsa bukhula, ukucindezela okukhiqizwa ngaphakathi kwepompo kuyehla. Uma ubude boketshezi oluhogeliwe budlula ububanzi obusebenzayo bepompo, ivacuum ingase yakheke ngaphakathi kwepompo. Lesi simo sizokwenza ukuthi igesi empompini icindezele, ithinte ukugeleza koketshezi futhi ibangele ngisho nokungasebenzi kahle kwepompo.

I-Liquid Vapor Pressure

Uketshezi ngalunye lunomfutho walo othize womhwamuko. Uma umfutho womhwamuko woketshezi useduze nomfutho womoya, uvame ukuhwamuka bese wenza amabhamuza. Ekwakheni kwepompo ye-axial split case, ukwakheka kwama-bubbles kungaholela ekungazinzini okuguquguqukayo okuguquguqukayo, futhi ezimweni ezimbi kakhulu, kungabangela i-cavitation, engagcini nje ukunciphisa ukusebenza kwepompo, kodwa futhi ingalimaza i-pump casing.

Imikhawulo yedizayini yesakhiwo

Idizayini yephampu isekelwe ezimisweni ezithile zemishini yoketshezi, futhi idizayini nempahla ye-impeller yayo ne-pump casing kuhlobene eduze nezici zayo zokusebenza. Ngenxa yezici zemvelo zephampu ye-axial split case, idizayini ayisekeli ibanga eliphakeme lokumunca, elinciphisa kakhulu ukusebenza kahle kwalo ebangeni lokudonsa elingaphezu kwamamitha amahlanu noma ayisithupha.

Isiphetho

Umkhawulo webanga lokumunca wephampu yekesi ehlukanisiwe ye-axial unqunywa izici eziningi njengokucindezela komkhathi, izici zoketshezi kanye nomklamo wepompo. Ukuqonda isizathu salo mkhawulo kuzosiza abasebenzisi benze izinqumo ezifanele lapho besebenzisa amaphampu futhi bagweme ukusebenza kahle kwemishini kanye nezinkinga zokwehluleka okubangelwa ukumunca ngokweqile. Okokusebenza okudinga ukumuncwa okukhudlwana, cabanga ukusebenzisa iphampu ezizibambayo noma ezinye izinhlobo zamaphampu ukuze uhlangabezane nezidingo ezithile zokusetshenziswa. Kuphela ngokukhetha imishini efanele kanye nokusetshenziswa lapho ukusebenza kwepompo kungasetshenziswa ngokugcwele.
