Pakati pezvinhu zvinokanganisa kunaka kwemagetsi defrost heat element, kunaka kwezvinhu ndicho chikonzero chakakosha. Inonzwisisika kusarudzwa kwezvinhu zvakasvibirira zve defrost kudziyisa chubhu ndiyo nhanho yekuve nechokwadi chemhando ye defrost heater.
1, iyo yekusarudza nheyo yepombi: tembiricha kuramba, ngura kuramba.
Kwemapombi etembiricha akadzika, BUNDY, aluminium pombi, pombi dzemhangura dzinowanzo shandiswa, uye tembiricha yakakwira mapombi anowanzo simbi isina tsvina pombi uye Ingle pombi. Ingle 800 heatig tube inogona kushandiswa mumamiriro ekushaya kunaka kwemvura, Ingle 840 yemagetsi ekupisa chubhu inogona kushandiswa mukupisa kwakanyanya kushanda mamiriro ane yakanaka oxidation kuramba, ine yakanaka corrosion resistance.
2, kusarudzwa kwekupikisa waya
Iyo yekupokana waya zvinhu zvinowanzo shandiswa mumagetsi defrost heat element ndeye Fe-Cr-Al uye Cr20Ni80 yekupikisa waya. Musiyano mukuru pakati pewaya mbiri dzekupikisa ndewekuti kunyungudika kwe0Cr25Al5 kwakakwira kupfuura kweCr20Ni80, asi pakupisa kwakanyanya, 0Cr25Al5 iri nyore kuita oxidize, uye Cr20Ni80 inogonawo kuchengetedza kushanda kwakadzikama pakupisa kwakanyanya. Naizvozvo, waya yekupikisa inoshandiswa pakupisa kwepamusoro kazhinji ndeye Cr20Ni80.
3, kusarudzwa kweMgO poda
Iyo MgO poda iri pakati petambo yekupokana uye madziro echubhu uye inoshandiswa kuvharisa pakati petambo yekupikisa uye madziro echubhu. Panguva imwecheteyo, MgO powder ine yakanaka yekupisa conductivity. Zvisinei, MgO powder ine yakasimba hygroscopic properties, saka inofanira kurapwa nekunyorova kwemvura (yakagadziridzwa MgO powder kana yakavharwa nemagetsi kupisa pombi) kana yakashandiswa.
MgO poda inogona kukamurwa kuita yakaderera tembiricha poda uye yakakwirira tembiricha hupfu zvinoenderana nekushisa kwemhando inoshandiswa. Yakadzika tembiricha hupfu inogona chete kushandiswa pazasi 400 ° C, kazhinji yakagadziridzwa MgO hupfu.
Iyo MgO poda inoshandiswa mupombi yekupisa yemagetsi inoumbwa nehupamhi hwakasiyana MgO hupfu zvidimbu zvinoenderana nechimwe chikamu (mesh ratio).
4, kusarudzwa kwezvinhu zvekuisa chisimbiso
Basa rekuisa chisimbiso nderokudzivirira hunyoro hwemuchadenga kupinda muMgO poda nemuromo wepombi, kuitira kuti MgO powder inyorove, kushanda kwekudzivirira kunoderedzwa, uye kupisa kwegetsi pombi kubuda uye kukundikana. Iyo yakagadziridzwa magnesia poda haigone kuiswa chisimbiso.
Zvinhu zvikuru zvinoshandiswa kuvhara magetsi ekupisa chubhu (kunyorova-uchapupu) igirazi, epoxy resin, silicone mafuta uye zvichingodaro. Mumagetsi ekupisa pombi yakavharwa nemafuta e-silicone, mushure mekupisa, mafuta e-silicone pamuromo wepombi ichave yakasvibiswa nekupisa, uye kuvhara kwepombi yekupisa kwemagetsi kuchaderera. Tembiricha yekudzivirira epoxy resin zvinhu haina kukwirira, uye haigone kushandiswa mumachubhu emagetsi ekupisa senge barbecue uye microwave oven ine tembiricha yakanyanya pamuromo wepombi. Girazi rine tembiricha yakakwira kuramba, asi mutengo wakakwira, uye unonyanya kushandiswa kuvhara mapombi ekupisa.
Mukuwedzera, pachava nesilicone tubes, silicone sleeves, porcelain beads, plastiki insulators uye zvimwe zvikamu mumuromo wepombi, kunyanya kuwedzera gaka remagetsi uye creepage kure pakati pemudonzvo uye simbi yemadziro emuromo wepombi. Silicone rubber inogona kutamba basa rekuzadza nekubatanidza.
Kana iwe uchifarira zvigadzirwa zvedu, pls taura nesu zvakananga!
