Iphampu yokuphakelayo kabhoyela wezigaba eziningi we-DG

Incazelo Yomkhiqizo
Iphampu yokuphakelayo ye-boiler yezigaba eziningi ye-DG iyiphampu ye-centrifugal enezigaba eziningi evundlile, elungele ukudlulisa amanzi ahlanzekile ngezinga lokushisa elingekho ngaphezu kuka-250 ° C, noma uketshezi olungagqwali olunezinto ezibonakalayo namakhemikhali ezifana namanzi, esetshenziswa kabanzi ku-Boiler feed amanzi ezitshalweni zamandla, i-metallurgy, ukufudumeza nezinye izimboni inokuphakama okuphezulu kwamamitha ayi-1800.I-casing yepompo yokuphakelayo kubhayela ingahlakazwa nge-axially ku-eksisi.Imbobo yokudonsa yephampu yohlobo lwe-DG85-80×8 iphezulu ngokuma iqonde phezulu, futhi indawo yokukhipha iphuma iqonde phezulu, eqonde kumugqa we-eksisi.Kusukela lapho uya ngasekugcineni kokushayela, isiqondiso sokuzungezisa sephampu yamanzi silandela iwashi.Ngokwezidingo zomsebenzisi, ingaphinda ikhiqize ukuzungezisa okuphambene newashi, futhi umsebenzisi angenza isicelo esikhethekile lapho e-oda.
Amapharamitha wokusebenza
Ibanga lepharamitha nencazelo yemodeli yohlobo lwe-DG yephampu yokuphakelayo yezigaba eziningi:

Uhlobo lwe-DG olunezigaba eziningi lwephampu yokuphakelayo uhlobo lwesakhiwo:
Lolu hlobo lwephampu ye-boiler yezigaba eziningi iyigobolondo elilodwa, ukumunca okukodwa, isakhiwo sephampu ye-centrifugal enezigaba eziningi.Iphampu enezigaba eziningi inokungena okume mpo kanye nendawo yokuphuma eqondile.Isakhiwo esithile simi kanje:
Ingxenye ye-Stator: Ikakhulukazi yakhiwe ingxenye engaphambili, ingxenye ephakathi, i-vane ye-guide, ingxenye engemuva, i-bearing frame kanye nesembozo segumbi lebhalansi.Izingxenye zixhunywe ngezinduku namantongomane.Izingxenye zangaphambili nangemuva zigxilile esihlalweni sepompo ngamabhawudi namantongomane.
Izingxenye ze-Rotor: ikakhulukazi i-impeller, umkhono ogcina i-impeller, umkhono obamba ibhalansi, i-balance disc kanye nezingxenye zemikhono ye-shaft ziqiniswa ngamantongomane amancane ayindilinga, futhi zigxilwe ku-shaft ngokhiye abayisicaba ukuze kuvinjelwe 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, okufanele ushintshwe lapho iphampu iguquliwe.
Indlela yebhalansi: Iphampu isebenzisa 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.
Indlela yokuzungezisa: Ibonwa kusukela ekugcineni kwenjini, iphampu izungeza ngokwewashi.
Impahla yezingxenye eziyinhloko: Ngaphandle kwe-DG85-80 ne-200DG43, izingxenye ezidlulayo zepompo zenziwe ngensimbi ekhonjiwe, kanti enye ingxenye yepompo yenziwe ngensimbi ekhonjiwe.
Ububanzi bamasethi aphelele: amasethi aphelele amaphampu okuphakelayo, amamotho, amavalufu okuhlola, amavalvu esango, izisekelo ezivamile noma izisekelo zazo.

Izinyathelo zokufaka iphampu:
1.1 Amalungiselelo
1.1.1 Ngaphambi kokuhlanganisa, zonke izingxenye zepompo, ikakhulukazi izindawo zokuqedela ukukhwelana, kufanele zihlanzwe kahle.
1.1.2 Bala zonke izingxenye, bese uhlukanisa bese ufaka izinombolo ngokulandelana kwezingxenye.
1.2 Ukuhlanganiswa kwezingxenye zephampu
1.2.1 Qaphela ukufaka iringi yokuvala engxenyeni ephakathi ukuze uyivimbele ukuthi ingawi.
1.2.2 Naka iphinikhodi elimele ukuzungezisa.
1.2.3 Qinisa inadi lomzimba wephampu ngokusebenzisa induku ngokulinganayo ukuze ugcine amandla afanele okuqinisa.Uma ixega kakhulu, izobangela ukuvuza kwendawo ehlangene yesigaba esiphakathi.Uma iqine kakhulu, izodala ukuguqulwa kwezingxenye ze-stator.Qinisa induku enentambo ngokulinganayo.
1.2.4 Ngemuva kokuthi intambo enentambo isiqinisiwe, sebenzisa inkomba yokudayela ukuthola ukuthi ingxenye yangaphambili nengemuva ayihambelani.1.3 Linganisa ivolumu yezintambo eziphelele ze-rotor, okufanele ihlangabezane nezidingo zomdwebo.
1.4 Faka ikhava yangaphambili kanye nekhava yesiphetho esinengcindezi ephansi kanye nesicathulo esiphansi, bese uphakamisela i-shaft endaweni emaphakathi.
1.5 Sebenzisa ithuluzi elikhethekile lokuphakamisa kanye negeji yokudayela ukuze uhlole ukuphuma kobuso bokuphela komkhono webhalansi, okufanele uhlangabezane nezidingo zomdwebo womhlangano ojwayelekile.
1.6 Hlanganisa izingxenye zerotha bese uqinisa nati lokukhiya.Inani leyunithi yezinhlamvu ezilinganisiwe ngemva kokufakwa kwepuleti lebhalansi lizohlangabezana nezimfuneko zomdwebo womhlangano ojwayelekile.
1.7 Faka isembozo sekhanda, isembozo somsila, umzimba othwalayo kanye nendawo engaphezulu yephedi yokuthwala kanye nendawo yokuvula nhlangothi zombili, okufanele ihlangabezane nenani elishiwo lezidingo zekhwalithi yephedi lokuthwala.
1.8 Lungisa isikhungo sesihlahla esithwalayo nhlangothi zombili, bese ukhiya inadi elilungisayo ngemva kokulungiswa.
1.9 Ukuhlanganisa i-thrust bear
1.9.1 Ukuze kuhlanganiswe izingxenye ezithwala ama-thrust, khuhla futhi ugaye amaphedi amnyama ngokwezidingo zezingxenye zokuthwala, futhi ama-thrust pads kufanele ajikeleze ngokuguquguqukayo ngesikhathi sokuhlanganisa.1.9.2 Ngemva kokufakwa kwe-thrust bear, igebe le-axial phakathi kwe-balance disc kanye nomkhono webhalansi kufanele libe ngu-0.04 ~ 0.08mm ngokuvumelana nezidingo zomdwebo womhlangano ojwayelekile, futhi ukulungiswa kwegebe kubonakala ngendandatho yokulungisa.
1.9.3 Ngemva kokulungisa imvume, faka i-thrust bear kanye ne-thrust plate, bese ukhiya nati lokukhiya.
Umzimba wepompo kanye nesembozo sepompo bakha igumbi lokusebenza le-impeller.I-inlet ne-outlet flanges ihlinzekwa ngezimbobo zesikulufu sepayipi zokufaka ama-vacuum gauge nama-pressure gauge, futhi ingxenye engezansi yomzimba wepompo ihlinzekwa ngezimbobo zesikulufu sepayipi ukuze kukhishwe amanzi asele.
I-impeller iwuhlobo oluvaliwe lokudonsa okukodwa.I-balance disc isethelwe ukulinganisa amandla amaningi we-axial.Ngesikhathi esifanayo, i-thrust bear inikezwa ukuthwala ingxenye encane ye-axial thrust engase ihlale.Ukuhlelwa kwe-bearing kugcina i-shaft isesimweni senduku yokudonsa ezinzile.I-impeller kumele ihlolwe ngokuqinile ukuthi ibhalansi emile ngaphambi kokuhlanganiswa ukuze kuqinisekiswe ukusebenza kahle.
I-pump shaft isekelwa ama-babbitt alloy sliding bearings amabili, afakwe emzimbeni ophethe ekumisweni kwepompo futhi agcotshwe ngamafutha amancane.
Kukhona indandatho yokuvala emzimbeni wepompo, engathuthukisa ukusebenza kahle kwe-volumetric yepompo.Ngakolunye uhlangothi, kungase futhi kuvimbele amanzi anengcindezi ephezulu ukuthi angagelezi abuyele egumbini lokuncela, aphazamise inkambu yokugeleza kwe-inlet yamanzi, nokuqinisekisa ukusebenza kokudonsa kwepompo.
I-shaft seal ngokuvamile iwuphawu oluthambile lokupakisha.Lapho iphampu isebenza, inani elincane le-medium lingangeniswa ebhokisini lokugxusha, futhi amanzi okupholisa nawokugcoba nawo angaxhunywa ngaphandle ukuze adlale indima yokuvala amanzi kanye nokupholisa kanye nokugcoba.Ngokwezidingo zomsebenzisi, uphawu lokupakisha lungashintshwa lube uphawu lomshini.
1.9.4 Lungisa indawo yokuphuma phakathi kwesihlalo esithwalayo kanye nepuleti lokusunduza ngomcamelo ukuze uqinisekise izidingo zokususa i-thrust bearing emdwebeni wokuhlanganisa.
