Iphampu ehlukanisayo yokuncela kabili yohlobo lwe-SH

Incazelo Yomkhiqizo

Amaphampu ohlobo lwe-S, SH anesiteji esisodwa, amaphampu aphakathi nendawo adonsa kabili ahlukaniseke ku-casing yepompo, asetshenziselwa ukumpompa amanzi ahlanzekile noketshezi olunezinto ezibonakalayo namakhemikhali afana namanzi.

Lolu hlobo lwepompo lunekhanda elingamamitha angu-9 ukuya ku-140, izinga lokugeleza elingu-126m³/h kuya ku-12500m³/h, futhi izinga lokushisa eliphezulu loketshezi akumele lidlule ku-80°C.Ilungele izimboni, izimayini, ukuphakelwa kwamanzi emadolobheni, iziteshi zikagesi, amaphrojekthi amakhulu okonga amanzi, ukuchelela ngenkasa emapulazini kanye nokukhipha amanzi.njll., amaphampu angu-48SH-22 amakhulu angasetshenziswa njengamaphampu ajikelezayo eziteshini zamandla ashisayo.

Incazelo yemodeli yepompo: njenge-10SH-13A

10—Ububanzi bembobo yokudonsa buhlukaniswa ngo-25 (okungukuthi, ububanzi bembobo yokudonsa yepompo ngu-250mm)

S, SH ukumunca okuphindwe kabili kwesigaba esisodwa sephampu yamanzi emaphakathi

I-13-Ijubane elithile lihlukaniswe ngu-10 (okungukuthi, ijubane elithile lepompo liyi-130)

A kusho ukuthi iphampu ishintshiwe ngama-impeller amadayamitha angaphandle ahlukene

Amapharamitha wokusebenza
Ibanga lepharamitha nencazelo yemodeli yohlobo lwe-SH lwesigaba esisodwa sokudonsa kabili kokugeleza okuvulekile kwephampu ye-centrifugal:
Ukugeleza (Q): 110—12020m3/h
Ikhanda (H): 8—140m

Imodeli: 6-SH-6-A
6- I-diameter ye-inlet yepompo ingamayintshi angu-6
Iphampu ehlukanisayo yokumunca kabili yesigaba esisodwa ye-SH-Horizontal
6 - 1/10 wejubane elithile lepompo liyindilinga
Ikhodi yokusika i-A-Impeller yangaphandle
Ukuhlanganisa, ukuqaqa kanye nokufakwa kwephampu yokuhlukanisa yohlobo lwe-SH
Izici zesakhiwo sohlobo lwe-SH lwesigaba esisodwa sokudonsa kabili kokugeleza okukhulu kwephampu ye-centrifugal:

Isakhiwo esihlangene: ukubukeka okuhle, ukuzinza okuhle nokufakwa kalula.
Ukusebenza okubushelelezi: I-impeller eklanywe kahle kakhulu yokudonsa kabili inciphisa amandla e-axial abe okungenani, futhi inephrofayili ye-blade esebenza kahle kakhulu ye-hydraulic.ukusebenza kahle okuphezulu.
Shaft seal: khetha BURGANN mechanical seal noma ukupakisha uphawu.Ingaqinisekisa amahora angama-8000 wokusebenza ngaphandle kokuvuza.
Ama-Bearings: Ama-bearings e-SKF kanye ne-NSK akhethiwe ukuze kuqinisekiswe ukusebenza kahle, umsindo ophansi nempilo ende yesevisi.
Ifomu lokufaka: Akukho ukulungisa okudingekayo ngesikhathi sokuhlanganiswa, futhi kungasetshenziswa ngokuya ngemibandela yendawo.Ukufakwa okuhlukile noma okuvundlile.

Ukuhlanganiswa nokuhlakazwa kohlobo lwe-SH lwesigaba esisodwa sokudonsa kabili kokugeleza okukhulu kwephampu ye-centrifugal:
1. Hlanganisa izingxenye ze-rotor: faka i-impeller, umkhono we-shaft, inati lomkhono we-shaft, umkhono wokupakisha, indandatho yokupakisha, indlala yokupakisha, indandatho egcina amanzi kanye nezingxenye zokuthwala ku-pump shaft ngokushintshana, futhi ufake indandatho yokuvala yokudonsa kabili, futhi bese ufaka i-Coupling.
2. Faka izingxenye ze-rotor emzimbeni wepompo, lungisa indawo ye-axial ye-impeller phakathi kwezindandatho ezimbili zokudonsa uphawu ezinhlangothini zombili ukuze uzilungise, futhi ubophe indlala yomzimba othwele ngezikulufo zokulungisa.
3. Faka ukupakisha, beka iphedi lephepha elivula maphakathi, umboze ikhava yepompo bese uqinisa iphinikhodi yomsila oyisikulufa, bese uqinisa inathi lekhava yepompo, bese ekugcineni ufake indlala ye-grave material.Kodwa ungacindezeli ukupakisha kakhulu, kuzobangela ukushisa kwe-bushing futhi kudle amandla amaningi, futhi ungayicindezeli ngokukhululekile, kuzodala ukuvuza okukhulu koketshezi futhi kunciphise ukusebenza kahle kwepompo.
Ngemuva kokuthi umhlangano usuqediwe, vula i-shaft yepompo ngesandla, akukho mkhuba wokuhlikihla, ukujikeleza kushelelezi futhi kulinganayo, futhi ukuhlakazeka kungenziwa ngokulandelana okuphambene komhlangano ongenhla.

Ukuhlola Ukufakwa:
1. Hlola ukuthi iphampu yamanzi kanye nenjini akufanele konakale.
2. Ubude bokufakwa kwephampu yamanzi, kanye nokulahlekelwa yi-hydraulic kwepayipi lokumunca, kanye namandla alo esivinini, akumele kube kukhulu kunevelu yobude bokudonsa obuvumelekile eshiwo isampula.Usayizi oyisisekelo kufanele ufane nosayizi wokufaka weyunithi yephampu.
3. Ukulandelana kokufakwa:
① Beka iphampu yamanzi kusisekelo sikakhonkolo esigqitshwe ngamabholiti okusetshenzwa kulengwa, lungisa izinga ngokulungisa i-spacer emise okweweji phakathi, bese uqinisa kahle amabhawodi okuhanjwa ngawo ukuze uvimbele ukunyakaza.
② Thela ukhonkolo ngemuva kwesisekelo kanye nonyawo lokumpompa.
③ Ngemva kokuthi ukhonkolo womile futhi uqinile, qinisa amabhawodi okusetshenzwa kulengwa futhi uhlole kabusha izinga lephampu yamanzi.
④ Lungisa ukugxila kwe-motor shaft kanye ne-shaft yepompo yamanzi.Yenza ama-shafts amabili ngendlela eqondile, ukubekezelelana kwe-coaxiality kumbuthano wangaphandle we-shafts emibili ngu-0.1mm, futhi ukubekezelelana kokungalingani kwegebe lobuso bokuphela eduze komjikelezo ngu-0.3mm (yihlole ngemva kokuxhuma amanzi. amapayipi okungena nawokuphuma kanye nokugijima kokuhlola) , kusafanele ahlangabezane nezidingo ezingenhla).
⑤ Ngemuva kokuhlola ukuthi ukuqondisa kwe-motor kuhambisana nokuqondisa kwepompo yamanzi, faka izikhonkwane zokuxhuma kanye nokuxhuma.
4. Amapayipi okungena namanzi okuphumayo kufanele asekelwe kubakaki abengeziwe, futhi akufanele asekelwe umzimba wepompo.
5. Itafula lokuhlangana phakathi kwephampu nepayipi kufanele liqinisekise ukucinana komoya okuhle, ikakhulukazi ipayipi elingenisa amanzi, okumele lingangeni emoyeni ngokuqinile, futhi akumele kube khona ukuvaleka komoya ocingweni.
6. Uma iphampu yamanzi ifakwe ngaphezu kwezinga lamanzi angenayo, kuvame ukufakwa ivalvu engezansi ukuze kuqaliswe iphampu.Indlela ye-vacuum diversion ingasetshenziswa.
7. Ngemva kwepompo yamanzi kanye nepayipi lokuphuma kwamanzi, ngokuvamile kuyadingeka ukufaka i-valve yesango kanye ne-valve yokuhlola (i-lift ingaphansi kwamamitha angu-20), futhi i-valve yokuhlola ifakwe ngemuva kwe-valve yesango.Indlela yokufaka echazwe ngenhla ibhekisela kuyunithi yepompo ngaphandle kwesisekelo esivamile.
Faka iphampu enesisekelo esivamile, futhi ulungise izinga leyunithi ngokulungisa ishim emise okweweji phakathi kwesisekelo nesisekelo sikakhonkolo.Bese uthela ukhonkolo phakathi.Izimiso zokufaka nezimfuneko ziyafana nalezo zamayunithi angenaso isisekelo esivamile.

Qalisa iphampu, yima bese ugijima:
1. Qala futhi ume:
Ngaphambi kokuqala, vula i-rotor yepompo, kufanele ibe bushelelezi futhi ilingane.
②Vala i-valve yesango lokuphuma, bese ujova empompini (uma ingekho i-valve engezansi, sebenzisa i-vacuum pump ukuze ukhiphe amanzi) ukuze uqinisekise ukuthi iphampu igcwele amanzi futhi awekho amaphakethe omoya.
③ Uma iphampu ifakwe igeji yevacuum noma igeji yokucindezela.Vala isisekelo se-rotary esixhunywe kwipompo bese uqala injini.Ngemuva kokuthi ijubane lijwayelekile, livule;bese uvula kancane kancane i-valve yesango lokuphuma.Uma ukugeleza kukhulu kakhulu, ungakwazi ukuvala kahle i-valve yesango elincane.Lungisa;ngaphandle kwalokho, izinga lokugeleza lincane kakhulu.Vula i-valve yesango.
④ Qinisa inadi lokuminyanisa endlaleni yokupakisha ngokulinganayo ukuze uketshezi luvuze ngamathonsi.Ngesikhathi esifanayo, qaphela ukuphakama kwezinga lokushisa endaweni yokupakisha.
⑤ Uma umisa ukusebenza kwephampu yamanzi, qala ngokuvala iqhude legeji yomshini wokukala amanzi kanye ne-pressure gauge kanye nevalvu yesango epayipini lokuphuma kwamanzi.Bese uvala amandla enjini.Njenge
Uma izinga lokushisa lendawo liphansi, ipulaki yesikulufu esiyisikwele engxenyeni engezansi yomzimba wepompo kufanele ivulwe, futhi amanzi kufanele asuswe ukuze kugwenywe ukubanda.⑥Uma ingasetshenziswa isikhathi eside, iphampu yamanzi kufanele ihlakazwe futhi amanzi kwezinye izingxenye kufanele asulwe ome.Faka amafutha e-anti-rust endaweni yokucubungula futhi uyigcine kahle.

Ukusebenza:
① Izinga lokushisa eliphezulu lephampu yamanzi akumele lidlule ku-75°C.
② Inani lebhotela elisekelwe ku-calcium elisetshenziselwa ukugcoba ukuthwala kufanele libe ngu-1/3 kuya ku-1/2 wesikhala somzimba othwele.
③ Uma ukupakisha kugqokwe, indlala yokupakisha ingacindezelwa kahle.Uma igqokwe kakhulu, kufanele ishintshwe.
④ Hlola izingxenye ze-shaft njalo.Naka ukukhuphuka kwezinga lokushisa kwe-motor bear.
⑤ Ngesikhathi sokusebenza, uma uthola ukubhonga noma eminye imisindo engajwayelekile, kufanele umise imoto ngokushesha.Hlola imbangela futhi uyiqede.
⑥ Ungakhulisi isivinini sephampu yamanzi ngokungenasizathu.Nokho, ingasetshenziswa ngesivinini esiphansi.Isibonelo, isivinini esilinganiselwe salolu hlobo lwepompo ngu-n, ukugeleza kungu-Q, i-lift ngu-H, amandla e-shaft ngu-N, futhi isivinini sincishiselwa ku-n1.Ku-Q1, H1 kanye ne-N1.Ubudlelwano babo bobabili.Ingaguqulwa ngefomula elandelayo:
Q1=(n1/n)Q H1=(n1/n)²H N1=(n1/n)³N
