Tarisa pane KUFANANA kumaodzanyemba kuNorth Water Transfer Project
2021-08-20
Musi waChivabvu 28, 2020, LIKE vharafu yakahwina bhidhi rekutenga chirongwa cheNeixiang mvura yekupa mvura yeNanyang mvura inotsigira chirongwa munzvimbo inogashira mvura yeSouth-to-North Water Transfer mudunhu reHenan, izvo zvakabatsira mukuderedza kushomeka. yezviwanikwa zvemvura kuchamhembe kweChina, kuona kugovaniswa kwakanaka kwezviwanikwa zvemvura, kuve nechokwadi chekusimudzira hupfumi uye nzanga uye kuvaka hurongwa hukuru hwehurongwa hwemagariro akanaka munzira yese. Mhedziso yePurojekiti yeKufambiswa kweMvura yeKumaodzanyemba kuenda kuMaodzanyemba Chirongwa cheKufambiswa kweMvura kubva kuMaodzanyemba kuenda kuNorth chirongwa chikuru chekuchengetedza mvura chiri kushanda muChina. Zviwanikwa zvemvura zvakawanda muChina muJianghuai River Basin zvinoendeswa kuNorth China neNorthwest China, nechinangwa chekushandura mamiriro ekudonha kwemvura kumaodzanyemba nekusanaya kwemvura kuchamhembe uye kushomeka kwakanyanya kwezviwanikwa zvemvura kuchamhembe, uye kusimudzira budiriro yehupfumi. nzanga, vanhu, zviwanikwa uye zvakatipoteredza kuMaodzanyemba neKuchamhembe. Chirongwa ichi chinoyambuka Rwizi Yangtze, Huaihe River, Yellow River uye Haihe River. Ndiyo yakakura kwazvo inter basin mvura yekufambisa chirongwa pasi rose, ine mari yakazara inodarika 500 bhiriyoni yuan. Eccentric hemispherical valve Eccentric hemispherical valve inoshandiswa muSouth-to-North Water Transfer Project. Eccentric hemispherical valve imhando itsva yevharuvhu yebhora. Iyo ine mamwe mabhenefiti akasarudzika echimiro chayo, senge pasina friction yekuchinja, yakaoma kupfeka kwechisimbiso uye kudiki kuvhura uye kuvhara torque. Izvi zvinoderedza saizi ye actuator. Yakashongedzerwa neakawanda kutenderera yemagetsi actuator, iyo yepakati inogona kugadziridzwa uye kugurwa zvakasimba. Inoshandiswa zvakanyanya mupetroleum, indasitiri yemakemikari, mvura yemudhorobha uye yekugezera uye mamwe mamiriro ekushanda anoda kuchekwa-kubviswa. Kushanda musimboti we eccentric hemispherical valve Eccentric hemispherical valve inoita kuti vharuvhu isavharwe kana kuvharika nekutenderedza cheni yevharuvhu. Ivhavha yebhora ine zvakanakira shanduko yemwenje uye vhoriyamu diki. Inogona kugadzirwa kuva dhayamita yakakura, chisimbiso chakavimbika, chimiro chakareruka uye kugadzirisa kuri nyore. Iyo yekuisa chisimbiso uye spherical surface inowanzovharwa, iyo isiri nyore kuparadzwa nepakati. Yakave ichishandiswa zvakanyanya mumaindasitiri akasiyana. Zvigadzirwa zve eccentric hemispherical valve ① Iyo eccentric hemispherical valve ndeyepamusoro akaiswa chimiro. Iyo valve yakaiswa papombi inogona kuongororwa zvakananga uye kugadziriswa pamhepo, iyo inogona kunyatso kudzikisa kuvharika kwechigadzirwa uye kuderedza mutengo. ② Iyo eccentric hemispherical valve igadziro yechigaro chimwe chete, iyo inobvisa dambudziko rekuti svikiro riri muvhavhavhavha rinokanganisa kushandiswa kwekuchengetedza nekuda kwekusimuka kwekumanikidza. ③ Iyo tsinde yevharuvhu ine yakaderera torque dhizaini uye yakakosha dhizaini dhizaini inogona kuvhurwa uye kuvharwa zviri nyore nekungobata diki. ④ Hapana kupokana pakati pekuvhura nekuvhara. Iri basa rinogadzirisa zvachose dambudziko rekuti kuiswa chisimbiso kwechinyakare [wiki] vharafu [/ wiki] kunokanganiswa nekupokana pakati pekuisa chisimbiso. ⑤ Wedge yekuisa chisimbiso chimiro: vharuvhu yakavharwa nekutsikirira bhora wedge pachigaro chevharuvhu nesimba remagetsi rinopihwa nevhavha hunde, kuitira kuti chisimbiso chevhavha chisakanganiswa nekushandurwa kwepombi yekusiyanisa kudzvanywa, uye kuiswa chisimbiso. kushanda kunovimbiswa zvakavimbika pasi pemamiriro akasiyana ekushanda. ⑥ Iyo yekuzvichenesa chimiro chekuvhara pamusoro peiyo eccentric hemispherical valve. Kana bhora richirerekera kure nechigaro chevharuvhu, mvura iri mupombi inopfuura nepanzvimbo yakavharwa yebhora zvakaenzana pa360 °, izvo zvisingangobvisi kukweshwa kwenzvimbo kwechigaro chevharuvhu nemvura inomhanya-mhanya, asi zvakare inosuka. kuunganidza pamusoro pechisimbiso chepamusoro kuti uwane chinangwa chekuzvichenesa. Muzana ramakore rechi21, SAKA vanhu vanoomerera kuchiono chekambani che "KUFANANA munyika, mupi anovimbika wekugadzirisa zvigadziriso zvemvura kumba nekune dzimwe nyika" uye huzivi hwebhizinesi hwe "mhando inogadzira kukosha", uye nekuenderera mberi nesimba "yakasimba." , zvine hungwaru, zvinoshanda uye zvinoshanda" Uye edza kuvaka bhizinesi rekudzidza rine mazano anotungamira. Uye anoda kushanda nevanhu vane njere kuti aite mipiro yakakura pakubvisa kweindasitiri yevharuvhu yeChina uye kufambira mberi kwebudiriro yevanhu!
