Kukhona ayisithupha 24-intshi icala lokuhlukanisa amaphampu amanzi ajikelezayo kule phrojekthi, afakwe endaweni evulekile. Imingcele ye-pump nameplate yilezi:

Q=3000m3/h, H=70m, N=960r/m (ijubane langempela lifinyelela ku-990r/m)

Ifakwe amandla emoto angu-800kW

Ama-flange emikhawulweni yomibili yokuhlanganiswa kwenjoloba yokwandisa axhunywe kumapayipi ngokulandelana, futhi ama-flange emikhawulweni yomibili ngokwawo awaxhumene ngokuqinile namabhawodi amade.

Ngemva kokubaiphampu yecala lokuhlukanisaifakiwe, ukulungisa iphutha kuqala ngakunye. Izimo ezilandelayo zenzeka ngesikhathi sokulungisa iphutha:

1. Kokubili isisekelo sephampu kanye nesinqe esigxilwe usimende sepayipi lokukhipha kuyasuswa. Isiqondiso sokufuduka njengoba kukhonjisiwe kumdwebo wohlelo lwedivayisi: iphampu iya kwesokudla, futhi isinqe esigxilile siya kwesokunxele. Izihlalo zikasimende zezinqenqema zephampu ziqhekekile ngenxa yokufuduka.

2. Ukufundwa kwegeji yokucindezela kufinyelela ku-0.8MPa ngaphambi kokuvulwa kwevalvu, futhi cishe ku-0.65MPa ngemva kokuvulwa kwevalvu kancane. Ukuvulwa kwe-valve butterfly kagesi cishe ku-15%. Ukukhuphuka kwezinga lokushisa kanye ne-vibration amplitude yezingxenye ezithwalayo kuvamile.

3. Ngemva kokumisa iphampu, hlola ukuqondanisa kwama-couplings. Kutholakala ukuthi ukuhlangana okubili komshini kanye nepompo akuhambelani kahle kakhulu. Ngokokuhlolwa kwesifaki, ukungaboni ngaso linye okubi kakhulu yipompo #1 (ukungalungi kahle okungu-1.6mm) kanye nepompo #5 (ukungalungi kahle). 3mm), iphampu engu-6# (inyakaziswa ngu-2mm), amanye amaphampu nawo anezintambo ezingamashumi zokungaqondani kahle.

4. Ngemva kokulungisa ukuqondanisa, lapho uqala kabusha imoto, umsebenzisi kanye nenkampani yokufaka basebenzisa inkomba yokudayela ukukala ukufuduka konyawo lwepompo. Umkhawulo wawungu-0.37mm. Kube khona ukubopha kabusha ngemva kokumiswa kwephampu, kodwa indawo yonyawo lwepompo ayikwazanga ukubuyiselwa.

Ingozi yeshafu ephukile yenzeke kupompo #5. Ngaphambi kokuthi kuphuke i-shaft yepompo engu-5#, yayigijima izikhathi ezi-3-4 ngezikhathi ezithile, kanti isikhathi esiphelele sokusebenza sasicishe sibe ngamahora angama-60. Ngemva kokushayela kokugcina, i-ekseli yaphuka ngesikhathi sokusebenza kuze kube ubusuku obulandelayo. I-shaft ephukile itholakala ekugcineni kwehlombe lokumisa i-drive end bear, futhi ingxenye yesiphambano ithambekele kancane enkabeni ye-shaft.

Ukuhlaziywa kwembangela yengozi: Ingozi yokuphuka kwe-shaft yenzeke kupompo engu-5#. Kungase kube nezinkinga ngekhwalithi ye-shaft ngokwayo noma izici zangaphandle.

1. I-shaft yepompo engu-5# iphukile. Ngeke kukhishwe ukuthi kunezinkinga zekhwalithi nge-5# pump shaft. Lezi zinkinga zingase zibe ukukhubazeka kokusebenza kwe-shaft ngokwayo, noma zingabangelwa ukugxila kwengcindezi okubangelwa ukucutshungulwa kwe-arc okungavamile kwe-5# pump shaft undercut groove. Lesi yisizathu esenza ukuthi i-5# shaft yepompo iphuke. I-eksisi idala izinkinga zobuntu.

2. I-shaft ephukile yepompo engu-5# ihlobene nokugudluka kwepompo okubangelwa amandla angaphandle. Ngaphansi kwesenzo samandla angaphandle, ukungaboni ngaso linye kwesobunxele nesokudla kokuhlangana kwepompo okungu-5# kukhulu. La mandla angaphandle akhiqizwa ngenxa yengcindezi edalwa ukucindezela kwamanzi epayipini lokukhipha (lokhu kushuba F lapho P2=0.7MPa:

F=0.7×10.2×(πd2)÷4=0.7×10.2×(π×802)÷4=35.9T, uma ivalvu ivaliwe, P2=0.8MPa, ngalesi sikhathi F=0.8×10.2×(π× 802 )÷4=41T), amandla amakhulu kangako okudonsa awakwazi ukumelana nokuqina kodonga lwepayipi lerabha, futhi kufanele adlulele kwesokunxele nakwesokudla. Ngale ndlela, amandla adluliselwa kwesokudla empompini, okubangela ukuba ihambe, futhi ngakwesobunxele kuya ku-pier kasimende, okubangela ukuthi uma i-buttress inamandla futhi ingawi, ukuthuthwa kwepompo kuya kwesokudla. kuzoba kukhulu. Amaqiniso abonise ukuthi uma ipayipi likasimende lephampu engu-5# lingaqhekeki, ukugudluzwa kwepompo engu-5# kuzoba kukhulu. Ngakho-ke, ngemva kokuma, ukungaboni ngaso linye kwesobunxele nesokudla kokuhlangana kwepompo engu-5# kuzoba okukhulu kakhulu (i-akhawunti yomphakathi: Pump Butler).

3. Ngenxa yokuthi ukuqina kodonga lwamapayipi enjoloba akukwazi ukumelana nokuphonswa kwamanzi okukhulu futhi kunwetshwe nge-axially, indawo yokuphuma yepompo ingaphansi kokuphonswa okukhulu kwangaphandle (i-inlet nama-flange ephumayo yepompo ayikwazi ukumelana namandla angaphandle epayipi), okwenza umzimba wephampu ugudluke futhi ukuhlangana kuhlakazeke. , imiphini emibili yomshini kanye nokuhlukaniswa iphampu yecala sebenzisa i-non-concentrically, okuyisici sangaphandle esibangela ukuphuka kwe-shaft yepompo engu-5#.

Isixazululo: Xhuma ngokuqinile izingxenye zamasondo ngezikulufu ezinde, futhi uvumele ipayipi lokukhipha ukuthi linwebe ngokukhululekile. Izinkinga zokufuduka kanye nokuphuka kwe-shaft ngeke zisavela.
