Munguva yekugadziriswa kweiyo mvura turbine jenareta unit, chimwe chekuchengetedza chinhu chemvura turbine chisimbiso chekugadzirisa.Chisimbiso chekuchengetedza hydraulic turbine chinoreva chisimbiso chinotakura chinodiwa panguva yekuvharwa kana kuchengetedza hydraulic turbine inoshanda chisimbiso uye hydraulic guide bearing, iyo inodzivirira kudzoka mugomba re turbine kana muswe wemvura wakakwira.Nhasi, tichakurukura akati wandei emhando dzeturbine chisimbiso kubva kune chimiro cheturbine main shaft chisimbiso.
Chisimbiso chekushanda che hydraulic turbine chinogona kukamurwa kuita
(1) Flat chisimbiso.Iyo flat plate seal inosanganisira imwe-layer flat plate seal uye kaviri-layer flat plate seal.Iyo imwechete-layer flat plate seal inonyanya kushandisa imwe-layer rabha ndiro kugadzira chisimbiso chine kumagumo kwesimbi isina tsvina inotenderera mhete yakamiswa pane huru shaft.Yakavharwa nekumanikidzwa kwemvura.Chimiro chayo chiri nyore, asi chisimbiso chekuita hachina kunaka sechisimbiso cheplate flat plate, uye hupenyu hwayo hwesevhisi hahuna kureba sehuya hwepiritsi flat plate seal.Iyo kaviri-layer flat plate ine yakanaka yekuisa chisimbiso, asi chimiro chayo chakaomarara uye mvura inodonha kana ichisimudza.Parizvino, inoshandiswawo mumadiki uye epakati-sized axial-flow units.
(2) Radial chisimbiso.Radial seal ine akati wandei-akaita se fan-kabhoni mabhuroko akatsikirirwa pahombe shaft nezvitubu musimbi-akaita fan-block blocks kuita layer yechisimbiso.Gomba diki remvura rinovhurwa mumhete yekuvharisa kuti ibudise mvura yadeuka.Inonyanya kuvharirwa mumvura yakachena, uye kusapfeka kwayo kwakashata mumatope ane mvura.Chisimbiso chimiro chakaoma, kuiswa uye kugadzirisa kwakaoma, kushanda kwechirimo hakusi nyore kuve nechokwadi, uye radial self-regulation mushure mekukwesha idiki, saka yakanyatso kubviswa uye yakatsiviwa nekuguma kwechiso chisimbiso.
(3) Kurongedza chisimbiso.Kurongedza chisimbiso chinoumbwa nemhete yepasi chisimbiso, kurongedza, mvura chisimbiso mhete, mvura chisimbiso pombi uye gland.Iyo inonyanya kuita basa rekuvhara nekurongedza pakati peyepasi chisimbiso mhete uye gland compression sleeve.Chisimbiso chinoshandiswa zvakanyanya muzvikamu zviduku zvakadzikama.
(4) Chisimbiso chechiso.Kumeso chisimbiso * * * Mechini mhando uye hydraulic mhando.Mechanical end face chisimbiso inotsamira pachitubu kudhonza disc yakashongedzerwa nedenderedzwa rabha block, kuitira kuti denderedzwa rabha block iri padyo nesimbi isina tsvina mhete yakamiswa pane huru shaft kuti iite chisimbiso basa.Mhete yekuisa chisimbiso yerabha inogadzikwa pamusoro pechivharo chepamusoro (kana chivharo chekutsigira) che hydraulic turbine.Iri rudzi rwechisimbiso chimiro chiri nyore uye chiri nyore kugadzirisa, asi simba rechirimo harina kuenzana, iro rinowanzoita eccentric clamping, kupfeka uye kusagadzikana kwekuisa chisimbiso kuita.
(5) Labyrinth mhete chisimbiso.Labyrinth ring seal rudzi rutsva rwechisimbiso mumakore achangopfuura.Nheyo yayo yekushanda ndeyekuti pombi ndiro mudziyo wakaiswa pamusoro peiyo turbine mumhanyi.Nekuda kwekusveta kwepombi ndiro, iyo huru shaft flange inogara iri mumhepo.Iko hakuna kushamwaridzana pakati pe shaft uye shaft chisimbiso, uye pane chete denga remhepo.Chisimbiso chine hupenyu hurefu hwebasa.Iyo huru shaft chisimbiso imhando isingabatanidzi labyrinth, iyo inoumbwa nesleeve inotenderera pedyo neshaft, bhokisi rekuvhara, main shaft seal drainage pombi uye zvimwe zvikamu.Pasi pekushanda kwakajairwa kweturbine, hapana kudzvanywa kwemvura pabhokisi rekuvhara mukati memutoro wese.Pombi yepombi pamumhanyi inotenderera nemumhanyi kudzivirira mvura nezvinhu zvakasimba kupinda muchisimbiso chikuru cheshaft.Panguva imwecheteyo, pombi yemvura yepombi yepombi inodzivirira jecha kana zvinhu zvakasimba kuti zvisaungane pasi pechivharo chepamusoro cheturbine yemvura, uye inobudisa mvura shoma shoma kuburikidza nemhete yepamusoro inomira kumvura yemuswe kuburikidza nepombi yemvura. yepureti yepombi.
Aya ndiwo mapoka mana makuru ematurbine seals.Muzvikamu zvina izvi, labyrinth mhete chisimbiso, sechisimbiso chitsva tekinoroji, inogona kunyatso kudzivirira kubuda kwemvura pabhokisi rekuvhara, iro rakagamuchirwa uye rinoshandiswa neakawanda hydropower zviteshi, uye kushanda kwekuita kwakanaka.
