Simbi chimiro sluice gedhi chinhu chakakosha chekudzora nhanho yemvura muzvimiro zvehydraulic senge hydropower station, reservoir, sluice uye kukiya ngarava. Inofanira kunyudzwa pasi pemvura kwenguva yakareba, nekuchinjana kazhinji kwekuoma uye kunyorova panguva yekuvhura nekuvhara, uye kushambidzwa nekuyerera kwemvura inomhanya. Kunyanya, chikamu chemutsetse wemvura chinokanganiswa nemvura, chiedza chezuva uye zvipenyu zvemumvura, pamwe nemafungu emvura, sediment, ice uye zvimwe zvinhu zvinoyangarara, uye simbi iri nyore kuita ngura, inoderedza zvakanyanya kubereka kwegedhi resimbi uye zvakanyanya. inokanganisa kuchengetedzwa kwehydraulic engineering. Zvimwe zvinodzivirirwa nekuvhara, izvo zvinowanzotadza mushure memakore 3 ~ 5 ekushandiswa, nekushanda kwakaderera kwekushanda uye mutengo wakakura wekugadzirisa.

Corrosion haingokanganisa kushanda kwakachengeteka kwechimiro, asi zvakare inodya yakawanda yevanhu, zvinhu uye mari zviwanikwa kuita basa rekurwisa-corrosion. Zvinoenderana nehuwandu hwemamwe mapurojekiti egedhi re sluice, kushandiswa kwepagore kwegedhi anti-corrosion account inosvika hafu yemutengo wepagore wekugadzirisa. Panguva imwecheteyo, nhamba huru yevashandi inofanira kuunganidzwa kuti ibvise ngura, pendi kana spray. Naizvozvo, kuitira kunyatso kudzora kukora kwesimbi, kurebesa hupenyu hwebasa regedhi resimbi uye kuve nechokwadi chekuvimbika uye kuchengetedzwa kwekuchengetedza mvura uye mapurojekiti emagetsi emvura, dambudziko renguva refu rinopesana nekuora kwegedhi resimbi rakakwezva kutarisisa kukuru.

Corrosion nharaunda yesimbi chimiro sluice gedhi uye zvinhu zvinokanganisa ngura:

1.Corrosion nharaunda yesimbi chimiro sluice gedhi

Mamwe magedhi esimbi sluice uye zvivakwa zvesimbi mukuchengetedza mvura uye mapurojekiti emagetsi emvura anonyudzwa mumhando dzakasiyana dzemvura (mvura yegungwa, mvura yakachena, tsvina yemaindasitiri, nezvimwewo) kwenguva yakareba; Vamwe vanowanzova munzvimbo yakaoma yakanyorova nekuda kwekuchinja kwemazinga emvura kana kuvhurwa kwegedhi nekuvhara; mamwe anozokanganiswawo nekumhanya kwemvura kuyerera uye kukweshera kwesediment, marara anoyangarara nechando; Chikamu chiri pamusoro pemvura kana pamusoro pemvura chinokanganiswawo nemhepo ine mwando yekubuda kwemvura uye mhute yemvura inoputika; Zvimiro zvinoshanda mumhepo inotapurwawo nechiedza chezuva nemhepo. Nekuti nharaunda yekushanda ye hydraulic gedhi yakashata uye kune zvakawanda zvinofurira zvinhu, zvinodikanwa kuti uongorore iyo corrosion factors.

2. Corrosion factors

(1) mamiriro ekunze: zvikamu zvemvura zvesimbi sluice gedhi zviri nyore kusvibiswa nezuva, mvura uye hunyoro mhepo.

(2) chimiro chepamusoro chechimiro chesimbi: roughness, mechanical damage, cavitation, welding defects, gap, etc. zvine simba guru pakuora.

(3) kushushikana uye deformation: iyo yakanyanya kushushikana uye deformation, iyo yakanyanya kukora.

(4) kunaka kwemvura: munyu wemvura yakachena wakaderera, uye kukora kwegedhi kunosiyana zvichienderana nekuumbwa kwaro kwemakemikari uye kusvibiswa; Mvura yegungwa ine munyu wakawanda uye maitiro akanaka. Mvura yegungwa ine ion yakawanda yechloride, iyo inoparadza zvakanyanya kusimbi. Kuora kwegedhi resimbi mumvura yegungwa kwakanyanya kudarika kuri mumvura yakachena.
