Lapho iphampu eyi-centrifugal iqaliswa, awekho amanzi epayipini lokuphuma lepompo, ngakho-ke akukho ukumelana namapayipi nokumelana nokuphakama kokuphakama. Ngemva kokuqaliswa kwepompo ye-centrifugal, inhloko yepompo ye-centrifugal iphansi kakhulu futhi ukugeleza kukhulu kakhulu. Ngalesi sikhathi, ukukhishwa kwe-pump motor (amandla we-shaft) kukhulu kakhulu (ngokuhambisana nejika lokusebenza kwepompo), okulula ukulayishwa, okuzolimaza i-pump motor kanye nesifunda. Ngakho-ke, vala i-valve yokuphuma lapho uqala, Ukuze wenze iphampu isebenze ngokujwayelekile. Ukuvala i-valve yokuphuma ilingana nokusetha ngokwenziwa ingcindezi yokumelana nepayipi. Ngemva kokuthi iphampu isebenza ngokujwayelekile, qalisa kancane i-valve ukuze wenze iphampu isebenze ngokujwayelekile isinyathelo ngesinyathelo ngokomthetho wejika layo lokusebenza.
Amaphuzu amabili kufanele aqinisekiswe ngaphambi kokuqala iphampu ye-centrifugal:
1. Gcwalisa isikhwama sepompo ngamanzi ukuze wenze i-vacuum;
2. I-valve epayipini lokuphuma kwamanzi kufanele ivalwe ukuze iphampu yamanzi ingenzi ukugeleza, okunganciphisa i-motor yokuqala yamanje futhi kube lula ukuqala kahle kwepompo yamanzi. Ngokuqala okushelelayo kwepompo yamanzi, i-valve yesango kufanele ivulwe kancane futhi ngesikhathi.
Iphampu ye-Centrifugal incike ekumunceni kwe-vacuum okwakhiwa amandla amaphakathi we-impeller ukuphakamisa amanzi. Ngakho-ke, lapho uqala iphampu ye-centrifugal, kufanele uqale uvale i-valve yokuphuma bese ugcwalisa amanzi. Lapho izinga lamanzi lidlula isikhundla se-impeller, iphampu ye-centrifugal ingaqalwa kuphela ngemva kokuba umoya osepompini ye-centrifugal ukhishwe. Ngemuva kokuqala, kwakhiwa i-vacuum ezungeze i-impeller ukuze imunce amanzi, engavuleka ngokuzenzakalelayo futhi iphakamise amanzi. Ngakho-ke, i-valve yokuphuma kufanele ivalwe kuqala.
Mayelana nephampu ye-centrifugal:
Iphampu ye-Centrifugal iyiphampu ye-vane, encike ku-impeller ejikelezayo. Enkambweni yokujikeleza, ngenxa yokuxhumana phakathi kwe-blade kanye ne-liquid, i-blade idlulisela amandla omshini ku-liquid, ukuze ingcindezi yoketshezi ingandiswa ukuze kuzuzwe inhloso yokudlulisa uketshezi. Iphampu ye-centrifugal inezici ezilandelayo:
1. Kukhona inani elilinganiselwe lekhanda elikhiqizwe iphampu ye-centrifugal ngesivinini esithile. Ukugeleza kwephoyinti lokusebenza namandla e-shaft kuncike esimweni sesistimu yedivayisi exhunywe kupompo (umehluko weleveli, umehluko wengcindezi nokulahlekelwa kwepayipi). Ikhanda liyahlukahluka ngokugeleza.
2. Ukusebenza okuzinzile, ukuthutha okuqhubekayo, futhi akukho pulsation of flow and pressure.
3. Ngokuvamile, ayinawo amandla okuzenzela. Kuyadingeka ukugcwalisa iphampu ngoketshezi noma ukhiphe ipayipi ngaphambi kokuqala ukusebenza.
4. Iphampu ye-centrifugal iqalwa lapho i-valve yokukhipha ipayipi ivaliwe, futhi iphampu ye-vortex kanye nepompo ye-axial flow iyaqalwa lapho i-valve ivuleke ngokugcwele ukuze kuncishiswe amandla okuqala.
Ngaphambi kokuthi iphampu iqale, igobolondo lepompo ligcwele uketshezi oluthuthiwe; Ngemuva kokuqala, i-impeller ijikeleza ngesivinini esikhulu esiqhutshwa yi-shaft, futhi uketshezi phakathi kwama-blades kumele futhi lujikeleze nalo. Ngaphansi kwesenzo samandla we-centrifugal, uketshezi luphonswa kusukela phakathi nendawo ye-impeller kuya emaphethelweni angaphandle futhi ithola amandla, ishiya umkhawulo wangaphandle we-impeller ngesivinini esikhulu futhi ingene endlini yepompo ye-volute.
Ku-volute, uketshezi luyancipha ngenxa yokwanda kancane kancane komzila wokugeleza, luguqule ingxenye yamandla e-kinetic ibe amandla okucindezela amile, futhi ekugcineni lugelezele epayipini lokukhipha ngomfutho ophakeme futhi luthunyelwe endaweni lapho ludingeka khona. Lapho uketshezi lugeleza lusuka enkabeni ye-impeller luye emaphethelweni angaphandle, kwakhiwa i-vacuum ethile phakathi nendawo ye-impeller. Njengoba ingcindezi engaphezu kwezinga le-liquid ye-tank yokugcina inkulu kunokucindezela ekungeneni kwepompo, uketshezi lucindezelwa ngokuqhubekayo ku-impeller. Kuyabonakala ukuthi inqobo nje uma i-impeller ijikeleza ngokuqhubekayo, uketshezi luzomuncwa futhi lukhishwe ngokuqhubekayo.
Ukuqala amanye amaphampu amaphakathi:
Okubalulwe ngenhla amaphampu e-centrifugal. Kwezinye izinhlobo zamaphampu, isimo simi kanje:
Izici ezinkulu zokuqalisa ukugeleza kwepompo ye-axial flow pump
Lapho i-valve evulekile egcwele iqala iphampu ye-axial flow, amandla e-shaft aphezulu ngaphansi kwesimo sokugeleza kwe-zero, okungama-140% ~ 200% wamandla alinganisiwe we-shaft, futhi amandla ubuncane bokugeleza okuphezulu. Ngakho-ke, ukuze kuncishiswe amandla okuqala, isici sokuqala samandla we-shaft kufanele kube ukugeleza okukhulu kokuqala (okungukuthi i-valve evulekile egcwele ukuqala).
02 izici zokuqala zephampu yokugeleza okuxubile
Lapho iphampu yokugeleza okuxubile iqalwa nge-valve evulekile egcwele, amandla e-shaft aphakathi kwamaphampu amabili angenhla ngaphansi kwesimo sokugeleza okuyiziro, okuyi-100% ~ 130% yamandla alinganiselwe. Ngakho-ke, izici zokuqala zepompo yokugeleza okuxubile kufanele futhi zibe phakathi kwamaphampu amabili angenhla, futhi kungcono ukuqala nge-valve egcwele evulekile.
03 izici zokuqalisa zephampu ye-vortex
Iphampu ye-valve evulekile yokuqala ye-vortex inamandla amakhulu we-shaft ngaphansi kwesimo sokugeleza okungu-zero, okungama-130% ~ 190% wamandla alinganiselwe we-shaft. Ngakho-ke, ngokufana nepompo yokugeleza kwe-axial, isici sokuqala sepompo ye-vortex kufanele kube ukuqala kokugeleza okukhulu (okungukuthi isiqalo esigcwele sevalvu evulekile).
