Iphampu ye-centrifugal ekwazi ukumelana nezimayini yohlobo lwe-MD

incazelo yomkhiqizo
Iphampu ye-centrifugal engavimbeki emayini yohlobo lwe-MD iyiphampu ye-centrifugal evundlile enezigaba eziningi, eyamukela imodeli ye-hydraulic yemikhiqizo esebenza kahle kakhulu neyonga amandla etuswa uhulumeni, futhi ithatha isikhundla esiphambili kwezobuchwepheshe imboni.Inezinzuzo zokusebenza kahle okuphezulu, ububanzi bokusebenza okubanzi, ukusebenza okuphephile nokuzinzile, umsindo ophansi, impilo ende, ukufakwa nokugcinwa okulula, njll. Lolu hlobo lwephampu ye-centrifugal enezigaba eziningi zokumba izimayini isetshenziselwa ukuthutha amanzi amaminerali angathathi hlangothi (usayizi wezinhlayiya). ngaphansi kuka-0.5 mm) enezinhlayiyana eziqinile ezingekho ngaphezu kuka-1.5% nezinye indle efanayo.Izitshalo zensimbi, ipayipi lemayini, ukuthuthwa kwendle nezinye izikhathi.

Amapharamitha wokusebenza
Incazelo yemodeli nezimo ezisebenzayo zephampu ye-MD ekwazi ukumelana nezigaba eziningi zezimayini:
MD155-67×9
I-MD—iphampu ye-centrifugal enezigaba eziningi yezimayini
155—Ukugeleza kwephoyinti lokuklama kwepompo ngu-155m3/h
67 – inhloko yephuzu lokuklama lesiteji esisodwa ingu-67m
9—inani lezigaba zephampu ngu-9

1. Ngaphansi kwesimo samanzi ahlanzekile (ngezinhlayiya eziqinile ezingaphansi kuka-0.1%), ukusebenza kahle ngeke kwehle ngaphezu kuka-6% ngemva kokugijima i-5000h ngaphandle kokulungiswa;
2. Ngaphansi kwesimo sokuthuthwa kwendle equkethe izinhlayiya eziqinile ngaphansi kwe-0.1% kuya ku-1%, egijima i-3000h ngaphandle kokulungiswa, ukwehla kokusebenza kahle akudluli u-5%;
3. Ngaphansi kwesimo sokuthuthwa kwendle equkethe izinhlayiya eziqinile ze-1-.5%, ukusebenza kahle ngeke kwehle ngaphezu kuka-6% uma kugijima i-2000h ngaphandle kokulungiswa okukhulu.
Izici zesakhiwo zohlobo lwe-MD lwephampu ye-centrifugal ekwazi ukumelana nezigaba eziningi zezimayini:

Ingxenye ye-stator ngokuyinhloko yakhiwe ingxenye yangaphambili, ingxenye ephakathi, i-vane yomhlahlandlela, ingxenye yangemuva, ifreyimu yokuthwala kanye nesembozo segumbi lebhalansi.Izingxenye zixhunywe nenduku namantongomane.Ingxenye yangaphambili kanye nengxenye yangemuva igxilile esihlalweni sepompo ngamabhothi namantongomane.
Izingxenye ze-rotor zenziwe ngokuyinhloko nge-impeller, i-impeller block, i-balance block, i-balance disc kanye nezingxenye zemikhono ye-shaft ziqiniswa ngamantongomane amancane ayindilinga, futhi zigxilwe ku-shaft ngezihluthulelo eziyisicaba ukuvimbela ukujikeleza.I-rotor yonke isekelwa kuma-bearings kuzo zombili iziphetho.I-rotor ixhunywe ngqo ku-motor nge-elastic pin coupling.
Ukuze kunxeshezelwe ukunwetshwa, i-pad toothed ifakwe phakathi kwesiteji sokugcina kanye nomkhono webhalansi, okumele kushintshwe lapho iphampu iguquliwe.
Iphampu yezigaba eziningi eyi-centrifugal yezimayini engagugi yamukela idivayisi yebhalansi ye-hydraulic balance engakwazi ukulinganisa ngokugcwele nangokuzenzakalelayo amandla e-axial.Lolu cingo lunezingxenye ezine: i-balance plate, i-balance plate, umkhono webhalansi kanye ne-balance block.
Ingxenye ye-rotor yohlobo lwe-MD yephampu ye-multistage centrifugal yezimayini yakhiwe ngokuyinhloko i-shaft kanye ne-impeller, umkhono we-shaft, i-balance disc nezinye izingxenye ezifakwe ku-shaft.Inombolo yama-impellers incike kwinani lezigaba zepompo.Izingxenye ku-shaft ziboshwe ngokhiye we-flat kanye ne-nati ye-shaft ukuze ihlanganiswe ne-shaft.I-rotor yonke isekelwa ama-bearings aginqikayo noma ama-sliding bears emikhawulweni yomibili.Ama-bearings anqunywa ngokusho kwamamodeli ahlukene, futhi akekho kuwo ophethe amandla e-axial.Amandla e-axial alinganiswe yi-balance disc.Ngesikhathi sokusebenza kwepompo, i-rotor ivunyelwe ukubhukuda nge-axially ku-casing yepompo, futhi ama-radial ball bearings awakwazi ukusetshenziswa.I-rolling bear igcotshwe ngamafutha, i-sliding bear igcotshwe ngamafutha amancane, futhi indandatho yamafutha isetshenziselwa ukuzigcoba, futhi amanzi ajikelezayo asetshenziselwa ukupholisa.Indawo yokuvala phakathi kwengxenye yokungena kwamanzi, ingxenye ephakathi nendawo kanye nengxenye yokukhipha amanzi yepompo konke kuvalwe ngamafutha e-molybdenum disulfide, futhi indandatho yokuvala kanye nomkhono we-vane wegayidi ufakwa phakathi kwengxenye ye-rotor nengxenye engashintshi ukuze ivalwe.Lapho izinga lokuguga nokukhala lithinte ukusebenza kwepompo, kufanele kushintshwe.
Izinhlobo zokuvala zamaphampu ezimayini aphakathi kwezigaba eziningi zifaka izigxivizo zemishini kanye nezigxivizo zokupakisha.Uma ipompo ivalwe ngokupakisha, indawo yendandatho yokupakisha kufanele ilungile, ukuqina kokupakisha kufanele kube okufanelekile, futhi kuhle ukuthi uketshezi lungakwazi ukudonsa ukwehla ngokudonsa.Izakhi ezihlukahlukene zokuvala zepompo zifakwe emgodini wokuvala, futhi i-cavity kufanele igcwaliswe ngamanzi okucindezela okuthile, futhi ukuvalwa kwamanzi, ukupholisa kwamanzi noma ukugcoba kwamanzi kuyakhethwa.I-bushing eshintshayo ifakwe uphawu lwe-shaft ukuvikela i-pump shaft.
Indlela yokuzungezisa yalolu hlobo lwephampu yezimayini enezigaba eziningi ihambisana newashi uma ibukwa kusukela ohlangothini lwenjini yoqobo.
Imiyalo yokuqala iphampu:

Ngaphambi kokuqala iphampu ye-centrifugal yezimayini ye-multi-stage, i-rotor yepompo kufanele ijikelezwe ukuze ihlole ukuthi i-rotor iyaguquguquka yini;
Hlola ukuthi isiqondiso se-motor siyahambisana yini nesiqondiso sepompo;
Vula ivalvu yokumunca iphampu, vala ivalvu yesango yepayipi lokuphuma kwepompo kanye neqhude legeji yokucindezela, ukuze iphampu igcwale uketshezi, noma usebenzise isistimu yokukhipha umoya ukuze ukhiphe umoya epayipini lokudonsa kanye nepompo;
Hlola ukuqina kwamabholithi okuxhuma epompo kanye nemoto kanye nokuphepha eduze kwepompo, ukuze iphampu isilungele ukuqala;
Qala injini.Ngemuva kokuthi iphampu isebenze ngokujwayelekile, vula iqhude legeji yokucindezela bese uvule kancane kancane ivalve yesango lokuphuma kwepompo kuze kube iphoyinti lokulinganisa umfutho likhomba ingcindezi edingekayo (lawula ukuphakama kwephampu ngokuya ngegeji yokuphuma komfutho wegazi).

Ukusebenza
Iphampu ye-centrifugal yezigaba eziningi engagugi yokumba isebenzisa indlela yebhalansi empompini ukulinganisa amandla e-axial.Uketshezi lwebhalansi lugeleza luphuma kudivayisi yebhalansi.I-liquid yebhalansi ixhunywe esigabeni sokungena kwamanzi kusukela epayipini lamanzi ebhalansi, noma ipayipi elifushane lenziwe ekamelweni lokulinganisa.Ishubhu ligeleza liphuma empompini.Ukuze kuqinisekiswe ukusebenza okujwayelekile kwepompo, ipayipi yamanzi ebhalansi akufanele ivinjelwe;
Enkambweni yokuqala nokusebenza, kufanele unake ukubuka ukufundwa kwamamitha, kungakhathaliseki ukuthi ukushisa okuthwalayo, ukuvuza kokupakisha nokushisa, nokudlidliza nomsindo wepompo kuyinto evamile.Uma kutholakala noma yisiphi isimo esingajwayelekile, kufanele kubhekwane naso ngesikhathi;
Ukushintsha kokukhuphuka kwezinga lokushisa kubonisa ikhwalithi yokuhlangana yephampu, ukukhuphuka kwezinga lokushisa akufanele kube ngaphezu kwezinga lokushisa elingu-35 ℃, futhi izinga lokushisa eliphakeme elithwalayo akufanele libe ngaphezu kuka-75℃;
Kukhona ukunyakaza okuthile kwe-axial ye-pump rotor ngesikhathi sokusebenza, futhi ukunyakaza kwe-axial kufanele kube phakathi kwebanga elivumelekile, futhi inani lokususa phakathi kobuso bokugcina bemoto kanye nokuhlanganisa okubili kwepompo yamanzi kufanele kuqinisekiswe;
Ngesikhathi sokusebenza kwepompo, ukugqokwa kwe-impeller, indandatho yokuvala, umkhono we-vane we-guide, umkhono we-shaft, i-balance disc nezinye izingxenye kufanele zihlolwe njalo.Uma ukugqokwa kukhulu kakhulu, kufanele kushintshwe ngesikhathi.

Ima
Ngaphambi kokuvala, iqhude legeji yokucindezela kufanele livalwe, futhi i-valve yesango lokuphumayo kufanele ivalwe kancane.Ngemuva kokuthi i-valve yokuphuma ivaliwe, injini kufanele ivalwe.Ngemuva kokuthi iphampu ime ngokuzinzile, i-valve yokudonsa yepompo kufanele ivalwe;amanzi empompini kufanele akhululwe.Ihlanzwe futhi yagcotshwa amafutha, yapakishwa ukuze igcinwe.
