Optical deformation (hari nzvimbo)
Optical deformation, inozivikanwawo se "even spot", idiki mana inopikisa pamusoro pegirazi. Chimiro chayo chakatsetseka uye chakatenderera, chine dhayamita ye0.06 ~ 0.1mm uye kudzika kwe0.05mm. Rudzi urwu rwekuremara kwemavara kunokuvadza kunaka kwegirazi uye kunoita kuti chinhu chinocherechedzwa chisvibe, saka chinodaidzwa zvakare kuti "light cross change point".
Iko kukanganiswa kweoptical deformation kunonyanya kukonzerwa nekugadziriswa kweSnO2 uye sulfides. Stannous oxide inogona kunyungudutswa mumvura uye ine kushanduka kukuru, nepo stannous sulfide ichiwedzera kushanduka. Mhepo yavo inonyunguduka uye zvishoma nezvishoma inoungana pane yakaderera tembiricha. Kana ichinge yaungana kune imwe nhanho, pasi pekukanganiswa kana kuzunguzika kwekuyerera kwemhepo, iyo condensed stannous oxide kana stannous sulfide inowira pamusoro pegirazi iyo isina kuomeswa zvachose uye inoita makwapa. Pamusoro pezvo, izvi zvinosanganiswa zvematani zvinogona zvakare kudzikiswa kuita simbi yesimbi nezvinhu zvinodzikisira mugasi rinodzivirira, uye madonhwe esimbi etani anozogadzirawo kukanganisa kwegirazi. Kana makemikoro emarata aumba makwapa pamusoro pegirazi pakupisa kwepamusoro, makorokoza madiki anozoumbwa pamusoro pegirazi nekuda kwekuvhuvhuta kwemakemikari aya.
Nzira huru dzekudzikisa hurema hwe optical deformation ndeyekudzikisa kusvibiswa kweokisijeni uye kusvibiswa kwesarufa. Kusvibiswa kweokisijeni kunowanzobva mukuronda mweya weokisijeni uye mhute yemvura mugasi rinodzivirira uye mweya weokisijeni inobuda uye ichipararira mugap retin. Tin oxide inogona kunyungudutswa mugasi remvura uye kunyungudutswa kuita gasi rinodzivirira. Iyo okisijeni mugasi rinodzivirira inotonhora uye inounganidzwa pamusoro pevhavha yekugezera yerata uye inowira pamusoro pegirazi. Girazi pacharo rinopawo kusvibiswa kweokisijeni, kureva kuti, iyo yakanyungudutswa yeokisijeni mumvura yegirazi ichapukunyuka mubhati retani, iro rinozowedzera oxidize simbi yesimbi, uye mhute yemvura iri pamusoro pegirazi inopinda munzvimbo yekugezera reti. , iyo inowedzerawo chikamu cheokisijeni mugasi.
Kusvibiswa kwesarufa ndiko chete kunounzwa mubhavhu rerata negirazi rakanyungudutswa kana nitrogen nehydrogen zvichishandiswa. Pamusoro pegirazi, hydrogen sulfide inobudiswa mugasi nenzira yehydrogen sulfide, iyo inopindirana netin kuti iite stannous sulfide; Pazasi pegirazi, sarufa inopinda mugasi remvura kuita stannous sulfide, inonyungudika mugasi remvura uye inoputika mugasi rinodzivirira. Iyo inogona zvakare kukwenenzverwa uye kuunganidza pazasi pechiso chevhavha yekugezesa yerata uye inowira pamusoro pegirazi pamusoro kuita mavara.
Naizvozvo, kuitira kudzivirira kuitika kwehurema huripo, zvinodikanwa kushandisa yakakwira-kumanikidza kudzivirira gasi kuchenesa iyo condensate ye oxidation uye sulfide sub couple pamusoro pebhati yekugezera kudzikisa deformation ye optical.
Kukwenya (abrasion)
Iko kukwenya pamusoro penzvimbo yakagadziriswa yeplate yepakutanga, iyo inoratidzika nguva dzose kana inopindirana, ndeimwe yezvakaremara zvekuonekwa kweplate yepakutanga uye inokanganisa maonero ekushanda kweplate yepakutanga. Kunonzi scratch kana kukwenya. Icho chirema chinoumbwa pamusoro pegirazi pamusoro neannealing roller kana chinhu chakapinza. Kana iyo scratch ichionekwa pamusoro pepamusoro pegirazi, inogona kunge yakakonzerwa netambo yekudziya kana thermocouple inowira pagirazi ribhoni kumashure kwehafu yekugezesa tin kana muchikamu chepamusoro chechoto cheannealing; Kana kuti pane chivakwa chakaoma segirazi rakaputsika pakati peplate yekumashure negirazi. Kana kukwenya kuchionekwa pazasi pechiso, chinogona kunge chakatyoka girazi kana mamwe maprism akanamira pakati pegirazi ndiro nerata yekugezera kuguma, kana bhandi regirazi rinokwesha pamucheto weti ellipsoid yekubuda nekuda kwekudzika kwekushisa kwekubuda kana kuderera kweti yemvura. kana kuti pane girasi rakaputsika pasi pebhanhire regirazi muhafu yekutanga ye annealing, etc. maitiro makuru ekudzivirira emhando iyi yekuremara ndeyekugara kuchenesa dhiraivha yekusimudza kuti uchengetedze roller surface inotapira; Chii zvakare, isu tinofanira kazhinji kuchenesa girazi slag uye mamwe marara pamusoro pegirazi kuderedza kukwenya.
The sub scratch ndiko kukwenya kwegirazi pamusoro kunokonzerwa nekukweshana kana kutapurirana kwasangana negirazi. Rudzi urwu rwekukanganisa runonyanya kukonzerwa nekusvibiswa kana kukanganisa pamusoro peiyo roller, uye chinhambwe chiri pakati pavo chingori denderedzwa remupumburu. Pasi pemaikorosikopu, kukwenya kwega kwega kunoumbwa kubva kumakumi kusvika kumazana ezvimedu zvidiki, uye nzvimbo yakatsemuka yegomba yakaita goko. Muzviitiko zvakakomba, kuputika kunogona kuoneka, kunyange kukonzera kuti ndiro yepakutanga iparadze. Chikonzero ndechekuti munhu akamira kana kumhanya hakusi kuenderana, roller deformation, roller surface abrasion kana kusvibiswa. Mhinduro ndeyekugadzirisa panguva yakakodzera tafura ye roller uye kubvisa tsvina mu groove.
Axial pateni zvakare imwe yehurema hwekukwenya kwegirazi, iyo inoratidza kuti pamusoro peplate yepakutanga inopa mavara eiyo indentation, iyo inoparadza yakatsetseka pamusoro uye mwenje transmittance yegirazi. Chikonzero chikuru chechimiro cheaxle ndechekuti ndiro yepakutanga haina kuomeswa zvachose, uye iyo asbestos roller inosangana. Kana chirema ichi chakanyanya, chinokonzeresa kutsemuka uye kuita kuti ndiro yepakutanga iparare. Nzira yekubvisa iyo axle pattern ndeyekusimbisa kutonhora kweplate yepakutanga uye kuderedza kupisa kwekuumba.
