Jiangsu HELIKE Fluid Technology Co., Ltd. inotsigira yakazara-yakazara yeDongxu Hydraulics.Iyo yakakosha mukutsvagisa nekusimudzira, dhizaini, kugadzirwa uye kutengesa kwealuminium plate-fin heat exchangers.
Mechanism yeVacuum Aluminium Brazing
Vacuum aluminium brazing tekinoroji inoshandisa aruminiyamu alloy ine yakaderera kunyungudika pane aruminiyamu seyakagadzika zvinhu.Iyi nzira inopisa weldment uye solder pamusoro pekunyunguduka kweiyo solder.Asi yakaderera pane tembiricha yekunyungudika kwesimbi yepasi, iyo solder yemvura inozadza kamukana kadiki pakati pezvishandiso zviviri nekupinza uye inopararira nesimbi yepasi, nekudaro inoona nzira yekubatanidza maworkpieces kuti ave welded.
Zvakanakira zveVacuumAaluminiumBrazing
①Tembiricha yekudziya yakadzikira, saka iyo yemuviri nemakemikari zvimiro zvesimbi yepasi haizokanganiswe kana kuita zvishoma.
② Zviuru zvema welds ezvikamu zvakaoma zvinogona kusungirirwa panguva imwe chete.
③Kuchinja kwezvikamu kudiki, uye zviri nyore kuona saizi yegungano.
④Kupisa munzvimbo yevacuum kunobatsira kubvisa girizi uye oxide firimu pamusoro peiyo workpiece, uye kupenya kwepamusoro kwezvikamu mushure mekukwirisa kwakakwira.
⑤Hapana flux inodiwa, hapana chikonzero chekuchenesa mushure mekucheka.
⑥ Kupisa uye kudzima (kana kumwe kupisa kupisa) kunogona kuitwa panguva imwe chete.
Hunhu uye Kuomerwa kweAluminium Alloy Brazing process
Nekuda kweiyo yakasarudzika yemuviri uye kemikari zvimiro zvealuminium alloy, nhevedzano yezvinetso uye hunhu huchamuka panguva yekugadzira brazing:
Iyo kemikari yealuminium inoita basa, uye kuwirirana kwayo neokisijeni kwakasimba kwazvo.Mumhepo pane tembiricha yemumba, kusanganiswa kwealuminium uye okisijeni kunoumba dense AL2O3firimu rine ukobvu hunosvika 0.1 μm.Iyo oxide firimu yakaoma kwazvo, uye nzvimbo yekunyunguduka yakakwira kusvika 2050 ° C, inopfuura nekure tembiricha yekunyungudika yealuminium alloy.Panguva imwecheteyo, ichadzivisawo kushamwaridzana kwakanaka pakati pesimbi, uye nyore nyore kuumba slag inclusions uye pores.Naizvozvo, iyo pre-welding kurapwa kwealuminium alloys uye kudzivirira kana kuderedzwa kweiyo oxide film kuumbwa mumamiriro ekupisa kwakakosha.Nokudaro, zvakakosha zvikuru kuchengetedza vacuum yakakwirira muchoto, kuderedza kuumbwa kwe oxide firimu kana kubvisa oxide firimu panguva yekugadzira, kunyanya muchikamu chekugadzirisa solder melting.
Kupisa kwekunyunguduka kwealuminium-based solder inongova 50-80 ° C yakasiyana kubva pakunyunguduka kweiyo main aluminium alloy, uye nzvimbo yekushanda idiki.Nokudaro, zvinodikanwa kuti zvisarudze zvine musoro solder uye uone kunyunguduka kwemutengesi, uye panguva imwechete, solder uye nheyo yesimbi inofanira kuva nekunyorova kwakanaka.
Kusarudzwa kwakarurama kwekushisa kwebrazing uye nguva yekubata kwakakosha zvikuru kuumba chibatanidzo chakanaka chebrazed uye kuvandudza simba rekubatana.
Kurongeka kwedimensional yezvikamu zvebrazing yakakwirira: semuenzaniso, iyo dimensional kushivirira kwefin processing inodzorwa pa ± 0.03mm maererano neruzivo rwedu, uye gungano remhando / kucheneswa kunofanirwawo kunyatsodzorwa.
