Ndeapi ari subjective zvinhu zvinokanganisa corrosion kuramba kwePD-0770 Clevis?
Raw materials
Q235B kabhoni simbi inoita ngura-inoshingirira, saka panodiwa kurapwa pamusoro. Kana basa rinotonhora richiomesa kana kusungirirwa kwekushushikana kwenzvimbo kukaitika panguva yekutsikirira nekugadzira, kugona kwe electrode kunogona kuderedzwa, zvichitungamira mukuora kwenzvimbo.
Corrosive media
Chloride ions mumhepo yepamhenderekedzo yegungwa inopinda mufirimu yeoxide pamusoro pezinc pamusoro, ichiita ne zinc uye inokurumidza kupera kwayo. Sulfur dioxide uye nitrogen oxides munzvimbo dzeindasitiri dzinosangana nemagasi ane acidic kuita mvura yeasidhi, zvichideredza kudzivirira.
Humidity
Nzvimbo ine hunyoro inochengeta pamusoro pekunyorova kwekavharo kwenguva yakareba, ichimhanyisa kukora kwezinc layer uye substrate.
Kana zvasvika pakurapwa kwepamusoro kwePD-0770 Clevis, galvanizing ndiyo sarudzo yekutanga. Kunze kwekuita galvanizing, ndeapi mamwe marapirwo epamusoro aripo?
Passivation kurapwa
Inoumba firimu rekuita pamusoro pechifukidzo, ichivandudza kusadzivirirwa kwayo uye kunamatira.
Phosphating kurapwa
Phosphating mafirimu anogona kudzivirira simbi corrosion kune imwe nhanho uye inogona zvakare kushandiswa seyekutanga isati yapenda kuvandudza pendi adhesion uye corrosion kuramba.
Oxidation kurapwa
Zvinhu zvakasvibirira zvakaiswa mune oxidizing mhinduro kuti iite 0.5μm-1.5μm Fe₃O₄ firimu pamusoro, iyo inobvisa kusara kunetseka uye kuderedza deformation.
Iyo PD-0770 Clevis inonyanya kushandiswa kubatanidza mapaneru ega kana mapaneru ega kune maviri mapaneru. "P" inomirira parallel bracket, "D" yepaneru imwe chete, uye "07" inoreva kutyora mutoro we70kN. Kana yakashandiswa pamwe chete nedzimwe hardware, haisi kungosangana nezvinodiwa zvekubatanidza kwemagetsi akasiyana-siyana, asiwo inosangana nezvinodiwa zvemazinga emagetsi epamusoro, kunyanya ayo ari pamusoro pe110kV.

Kana ikashandiswa munzvimbo inotyisa zvikuru, iyo PD-0770 Clevis pamusoro inofanira kucheneswa kana kuputirwa nependi inorwisa ngura makore ese 2-3 kudzivirira kupindira kwezvinosvibisa midhiya, kuwedzera hupenyu hwayo hwesevhisi, uye kuve nechokwadi chekushanda kwakachengeteka kwetambo yemagetsi.
Iyo PD-0770 Clevis iri nyore kuisa. Gadzirisa maburi maviri ekubatanidza evhavha nemaburi ekubatanidza eiyo hardware ari padyo kuti ave nechokwadi chekuti chirairo uye hardware zvakabatana uye kudzivirira kusarongeka mushure mekuiswa. Isa mabhaudhi ane simba repamusoro-soro nemisoro yebhaudhi yakatarisa kure nekwainobva simba, ichisiya tambo mbiri kusvika nhatu dzenati dziri pachena. Shandisa torque wrench kuomesa mumatanho maviri kune yakatarwa torque kudzivirira deformation inokonzerwa nekuwedzeredza munhanho imwe. Mushure mekuiswa, iyo PD-0770 Clevis inofanirwa kuongororwa kuti iite sei uye inongoiswa mukushandiswa mushure mekupfuura ongororo.
