Iimpompo ze-Multistage zizixhobo eziphambili zokuphatha ulwelo ezilungiselelwe ukuhambisa ukusebenza koxinzelelo oluphezulu ngokusebenzisa i-impellers ezininzi ngaphakathi kwecasing enye yempompo. Iimpompo ze-Multistage zenzelwe ukuphatha ngokufanelekileyo uluhlu olubanzi lwezicelo ezifuna amanqanaba aphakamileyo oxinzelelo, njengokunikezelwa kwamanzi, iinkqubo zoshishino, kunye neenkqubo zokukhusela umlilo.

Ulwakhiwo lweIimpompo ze-Multistage ezithe nkqo
Ubume bempompo yePurity nkqo inokwahlulwa ibe ngamacandelo amane aphambili: isitator, rotor, iibheringi, kunye neshaft seal.
1.Stator: Iimpompo ye-centrifugalI-stator yenza undoqo weendawo ezimileyo zempompo, eziquka izinto ezininzi ezibalulekileyo. Ezi ziquka i-suction casing, icandelo eliphakathi, i-diffuser casing, kunye ne-diffuser. Amacandelo ahlukeneyo e-stator ahlanganiswe ngokukhuselekileyo kunye neebholiti zokuqinisa, ukudala igumbi elisebenzayo eliqinileyo. Ipompo yokufunxa i-centrifugal casing kulapho ulwelo lungena khona kwimpompo, ngelixa i-discharge casing kulapho ulwelo luphuma khona emva kokufumana uxinzelelo. Icandelo eliphakathi ligcina i-vanes ekhokelayo, enceda ukuqondisa ulwelo ngokufanelekileyo ukusuka kwelinye inqanaba ukuya kwelinye.
2.Rotor: Iimpompo ye-centrifugal ethe nkqoI-rotor yinxalenye ejikelezayo yempompo ye-centrifugal kwaye ibalulekile ekusebenzeni kwayo. Iqukethe i-shaft, i-impellers, i-bancing disc, kunye nemikhono ye-shaft. I-shaft ihambisa amandla ajikelezayo ukusuka kwi-motor ukuya kwii-impellers, ezijongene nokuhambisa ulwelo. Ii-impellers, ezifakwe kwi-shaft, zenzelwe ukunyusa uxinzelelo lwamanzi njengoko luhamba ngempompo. I-disc yokulinganisa lelinye icandelo elibalulekileyo elichasene ne-axial thrust eyenziwe ngexesha lokusebenza. Oku kuqinisekisa ukuba i-rotor ihlala izinzile kwaye ipompo isebenza kakuhle. Imikhono ye-shaft, ebekwe kuzo zombini iziphelo ze-shaft, zizinto ezinokutshintshwa ezikhusela i-shaft ekugugile.
I-3.Bearings: Iibheringi zixhasa i-shaft ejikelezayo, iqinisekisa ukusebenza kakuhle kunye nokuzinza. Iimpompo zenqanaba elithe nkqo zisebenzisa iindidi ezimbini zeebheringi: iibheringi eziqengqelekayo kunye neebheringi ezityibilikayo. Iibheringi eziqengqelekayo, ezibandakanya ukuthwala, ukuthwala izindlu, kunye nekepusi yokuthwala, zithanjiswa ngeoyile kwaye ziyaziwa ngokuqina kwazo kunye nokukhuhlana okuphantsi. Iibheringi ezityibilikayo, kwelinye icala, zenziwe ngokuthwala, ukugquma, ukugquma iqokobhe, isigqubuthelo sothuli, igeyiji yomgangatho we-oyile, kunye neringi yeoli.
4.I-Shaft Seal: Isitywina se-shaft sibalulekile ekuthinteleni ukuvuza kunye nokugcina ingqibelelo yempompo. Kwiimpompo zenqanaba elithe nkqo, i-shaft seal ikholisa ukusebenzisa isitywini sokupakisha. Eli tywina lenziwe ngumkhono wokutywina kwibhokisi yokufunxa, ukupakisha, kunye neringi yokutywina yamanzi. Izinto zokupakisha zipakishwe ngokuqinileyo kwi-shaft ukunqanda ukuvuza kwamanzi, ngelixa umsesane wokutywina wamanzi unceda ukugcina ukusebenza kwetywina ngokuyigcina ithambisa kwaye ipholile.

Umgaqo-siseko wokuSebenza weePumpu ze-Vertical Multistage
Iimpompo ze-centrifugal ezithe nkqo zisebenza ngokusekwe kumgaqo wamandla ombindi, ingqikelelo esisiseko kwi-fluid dynamics. Umsebenzi uqala xa i-motor yombane iqhuba i-shaft, ibangela ukuba i-impellers ezifakwe kuyo zijikeleze ngesantya esiphezulu. Njengoko i-impellers ijikeleza, ulwelo olungaphakathi kwimpompo luphantsi kwamandla e-centrifugal.
La mandla atyhalela ulwelo ngaphandle ukusuka kumbindi we-impeller ukuya emphethweni, apho afumana zombini uxinzelelo kunye nesantya. Ulwelo ke luhamba lutyhutyha i-vanes yesikhokelo luze luye kwinqanaba elilandelayo, apho ludibana nenye i-impeller. Le nkqubo iphinda iphindwe kwizigaba ezininzi, kunye ne-impeller nganye yongeza kuxinzelelo lolwelo. Ukunyuka kancinci koxinzelelo kuzo zonke izigaba yinto eyenza ukuba iimpompo ze-multistage zikwazi ukuphatha izicelo zoxinzelelo oluphezulu ngokufanelekileyo.
Uyilo lwee-impellers kunye nokuchaneka kwee-vanes ezikhokelayo zibalulekile ekuqinisekiseni ukuba ulwelo luhamba ngokufanelekileyo kwinqanaba ngalinye, ukufumana uxinzelelo ngaphandle kokulahlekelwa okukhulu kwamandla.
