Yini Isizathu Sokudlidliza Okukhulu Kwephampu Ye-turbine Emile?
Ukuhlaziywa kwezimbangela zokudlidliza kwe- iphampu ye-turbine eqondile
1. Ukudlidliza okubangelwa ukufakwa nokuphambuka komhlangano we-iphampu ye-turbine eqondile
Ngemva kokufakwa, umehluko phakathi kwezinga lomzimba wepompo kanye nephedi yokuphonsela kanye nokuma kwepayipi eliphakamisayo kuzodala ukudlidliza komzimba wephampu, futhi lawa manani amathathu okulawula nawo ahlobene ngokwezinga elithile. Ngemuva kokufakwa komzimba wepompo, ubude bepayipi lokuphakamisa kanye nekhanda lepompo (ngaphandle kwesikrini sokuhlunga) buyi-26m, futhi zonke zimisiwe. Uma ukuchezuka okuqondile kwepayipi eliphakamisayo kukukhulu kakhulu, iphampu izobangela ukudlidliza okukhulu kwepayipi eliphakamisayo kanye ne-shaft lapho iphampu ijikeleza. Uma ipayipi lokuphakamisa liphezulu kakhulu, ukucindezeleka okuhlukile kuzokwenziwa ngesikhathi sokusebenza kwepompo, okuholela ekuphukeni kwepayipi lokuphakamisa. Ngemva kokuba iphampu yomthombo ojulile ihlanganiswe, iphutha lokuma kwepayipi lokuphakamisa kufanele lilawulwe ngaphakathi kuka-2mm phakathi kobude obuphelele. Iphutha eliqondile nelivundlile ngu-0 futha.05/l000mm. Ukubekezelelwa kwebhalansi okumile kwe-impeller yekhanda lepompo akukho ngaphezu kwe-100g, futhi kufanele kube ne-8-12mm imvume ye-serial ephezulu naphansi ngemva kokuhlanganiswa. Iphutha lokufaka nokuhlanganisa liyisizathu esibalulekile sokudlidliza komzimba wepompo.
2. Isivunguvungu se-shaft yokushayela yepompo
I-Whirl, eyaziwa nangokuthi "i-spin", iwukudlidliza okuzijabulisa ngokwakho kwe-shaft ezungezayo, engenazo izici zokudlidliza kwamahhala futhi okungelona uhlobo lokudlidliza okuphoqelelwe. Ibonakala ngokunyakaza okujikelezayo kwe-shaft phakathi kwama-bearings, okungenzeki lapho i-shaft ifinyelela isivinini esibucayi, kodwa ivela ebangeni elikhulu, elingaphansi elihlobene nesivinini se-shaft ngokwayo. Ukushwibeka kwepompo yomthombo ojulile kubangelwa ikakhulukazi ukungonisela okunganele. Uma igebe phakathi kwe-shaft kanye ne-bearing likhulu, isiqondiso sokujikeleza siphambene nalokho kwe-shaft, okubizwa nangokuthi ukugubha kwe-shaft. Ikakhulukazi, i-drive shaft yepompo yomthombo ojulile yinde, futhi imvume efanelekile phakathi kwe-rubber bear kanye ne-shaft ingu-0.20-0.30mm. Uma kukhona imvume ethile phakathi kwe-shaft kanye ne-bearing, i-shaft ihlukile kune-bearing, ibanga eliphakathi likhulu, futhi imvume ayinakho ukugcotshwa, njenge-deep well pump rubber bearing lubrication Ipayipi lokuhambisa amanzi liphukile. Kuvinjiwe. Ukungasebenzi kahle kuholela ekutheni amanzi anganele noma angafiki ngesikhathi, futhi maningi amathuba okuthi anyakaze. Ijenali ixhumene kancane ne-rubber bear. Ijenali ingaphansi kwamandla we-tangential we-bearing. Isiqondiso samandla siphambene nesiqondiso sejubane le-shaft. Ngasohlangothini lokusika lwephuzu lokuxhumana lodonga olunodonga, kunokuthambekela kokuya phansi, ngakho-ke iphephabhuku ligingqika nje odongeni oluthwele, olulingana nepheya lamagiya angaphakathi, enze ukunyakaza okuzungezayo okuphambene nendawo ukujikeleza kwe-shaft.
Lokhu kuqinisekiswe yisimo ekusebenzeni kwethu kwansuku zonke, okuzokwenza futhi ukuthi i-rubber bear ishe isikhashana.
3. Ukudlidliza okubangelwa ukugcwala kakhulu kwephampu ye-turbine eqondile
I-thrust pad yomzimba wepompo isebenzisa ingxubevange ye-babbitt esekelwe ku-tin, futhi umthwalo ovunyelwe ngu-18MPa (180kgf/cm2). Lapho umzimba wepompo uqalwa, ukuthambisa kwe-thrust pad kusesimweni sokugcotshwa komngcele. I-valve yovemvane kagesi kanye ne-valve yesango esebenza ngesandla ifakwe endaweni yokuphuma kwamanzi emzimbeni wepompo. Lapho iphampu iqala, vula i-valve butterfly kagesi. Ngenxa yokufakwa kwe-silt, i-valve plate ayikwazi ukuvulwa noma i-valve yesango eyenziwa ngesandla ivaliwe ngenxa yezinto zomuntu, futhi i-exhaust ayifika ngesikhathi, okuzokwenza ukuthi umzimba wepompo udlidlize ngamandla futhi i-thrust pad izosha ngokushesha.
4. Ukudlidliza okunyakazayo lapho kuphuma khona iphampu ye-turbine eqondile.
Imishini yokumpompa isethwe ngokulandelana. Ipayipi elifushane le-Dg500. Hlola i-valve. I-valve butterfly kagesi. I-valve yezandla. Ipayipi elikhulu nesinqamuli sesando samanzi. Ukunyakaza kwamanzi okuguquguqukayo kukhiqiza into engavamile yokuphefumula. Ngaphandle kokuvinjelwa kwe-valve ngayinye, ukumelana kwendawo kukhulu, okuholela ekwandeni komfutho nokucindezela. Izinguquko, ezisebenza ngokudlidliza kodonga lwepayipi kanye nomzimba wephampu, zingakwazi ukubona ukwenzeka kwe-pulsation yenani legeji yokucindezela. Izinkambu ze-pulsating kanye nesivinini sokugeleza kwe-turbulent zidluliselwa ngokuqhubekayo emzimbeni wephampu. Uma imvamisa ebusayo yokugeleza kwesiyaluyalu ifana nemvamisa yemvelo yesistimu yepompo yomthombo ojulile, isistimu kufanele imunce amandla futhi ibangele ukudlidliza. Ukuze unciphise umphumela walokhu kudlidliza, i-valve kufanele ivuleke ngokugcwele futhi i-spool kufanele ibe ubude nokusekelwa okufanele. Ngemva kwalokhu kwelashwa, inani lokudlidliza lehliswa kakhulu.
5. Ukudlidliza kwe-torsional kwepompo eqondile
Ukuxhumana phakathi kwepompo yomthombo ojulile we-shaft kanye ne-motor ithatha ukuhlangana okunwebekayo, kanti ubude be-drive shaft bungama-24.94m. Ngesikhathi sokusebenza kwepompo, kune-superposition yokudlidliza okuyinhloko kwamafrikhwensi e-angular ahlukene. Umphumela wokuhlanganiswa kwama-resonance amabili alula kumafrikhwensi e-angular ahlukene akusho ukuthi ukudlidliza okulula kwe-harmonic, okungukuthi, ukudlidliza kwe-torsional okunamadigri amabili enkululeko emzimbeni wephampu, okungenakugwenywa. Lokhu kudlidliza kuthinta kakhulu futhi kulimaze ama-thrust pads. Ngakho-ke, esimweni sokuqinisekisa ukuthi i-thrust pad yendiza ngayinye ine-oyela wedge ehambisanayo, shintsha uwoyela ongu-68# oshiwo emishinini yokuqala engahleliwe ibe ngu-100# uwoyela ukuze ukhuphule i-viscosity kawoyela wokugcoba we-thrust pad futhi uvimbele ifilimu yokugcoba nge-hydraulic. we-thrust pad. ukwakheka nokugcinwa.
6. Ukudlidliza okubangelwa ithonya elihlangene lamaphampu afakwe kugongolo olufanayo
Iphampu yomthombo ojulile kanye nenjini kufakwe ezingxenyeni ezimbili ezingu-1450 mmx410mm emishayweni yohlaka lukakhonkolo oluqinisiwe, isisindo esigxilile sepompo ngayinye kanye nemoto yi-18t, ukudlidliza okusebenzayo kwamaphampu amabili ancikene kuhlaka lohlaka olufanayo kungenye isistimu yokudlidliza yamahhala emibili. Lapho ukudlidliza kwenye yezinjini kudlula indinganiso ngokungathi sína futhi ukuhlolwa kusebenza ngaphandle komthwalo, okungukuthi, ukuhlanganisa okunwebekayo akuxhunyiwe, futhi inani le-amplitude lemoto lenye ipompo ekusebenzeni okuvamile likhuphukela ku-0.15mm. Lesi simo akulula ukusibona, futhi kufanele sinakwe.
