Uyini nokunamathisela ngomthofu ka amashubhu zethusi

Nokunamathisela ngomthofu - inqubo uxhumano izakhi esakhiwe ngezinto ezahlukene, ngokwethula a solder phakathi kwazo. Ngaphezu kwalokho, le nto has a ukuma leliphasi kunaleyo ezinye izingxenye. eyohlinzwa ezinjalo kusetshenziswa kakhulu njengoba iningi eliphezulu isibopho indlela. Brazing zethusi tubing ukunweba ukuphila kwakwakhe ezinjalo, ukubekwa uphawu yayo ezivuzayo sicindezelekile, ukuqinisekisa ukumelana ukugqwala.

Ngaphambi kokuthi uqale bewumsebenzi akho, kuyinto efiselekayo bajwayelane izingxenye eziyisisekelo ukuze yabo ukuvimbela ukubukeka izimbungulu engadingeki bese ekugcineni okuhle uxhumano izinga.

Okwenziwe nokunamathisela ngomthofu zethusi amapayipi nge solder esithambile noma esiqinile. Indaba yokuqala isetshenziswa ezingeni lokushisa mayelana 425 ° C, futhi izinga lokushisa yesibili kuvunyelwe bengase bazikhandlele 560 ° C. Icacisa uhlobo solder incike lingakanani ithusi kanye nezinye izinto ezitholakala ngezithako zawo. Esimweni lapho solder ngoba nokunamathisela ngomthofu zethusi tube iqukethe esiliva, izinga lokushisa yayo ukuncibilika kumele kungancipha.

Ukuze uthole okuhle uxhumano izinga, kungcono ukusebenzisa izakhi zethusi phosphor, kodwa ukuncibilika yabo iphuzu kuqhathaniswa esiliva iphezulu kakhulu. Ukuze zethusi zethusi nethusi-zethusi izinto meltable esetshenziswa yokucucuza nokunamathisela ngomthofu amapayipi zethusi. Ukusetshenziswa Its okulingana bula mechanical izingxenye ngaphambi inqubo, okuyinto ukuvimbela ukuvela i ifilimu oxide, okuyinto ngempela ebalulekile kule nqubo. Ngokuvamile ecucuza isetshenziswa kokuba ngendlela unamathisele, lapho nokunamathisela ngomthofu amapayipi zethusi uzobe kakhulu lula.

Ukuze ugweme amaphutha izingxenye kwakwakhe, ke iyadingeka futhi banamathele emithethweni ethile. Egcekeni kumele kuhlanzwe umenshaetsya ilangabi, okuyinto kwakha Ukushisa esiphezulu. Kuyadingeka ukuba afeze degreasing metal evele. Izikhala emkhatsini wetincenye teluhlaka kanye ezikhundleni zawo ezilinganiselwe kufanele ihlolwe ngokucophelela.

Brazing zethusi tubing yakhiwa isicelo kusuka ngaphandle kwakwakhe nengcosana yokucucuza. Futhi, indawo ukuze lokhu ukufudunyezwa nombala kuya lokushisa edingekayo. Khona-ke, kungenzeka solder imali kwi lemagalagala is nombala basakaza therein by brazing ithoshi. Ngesimo ezibunjiwe, ke uyogeleza isiqondiso okuhlangana kuyo, okuyinto evuthayo ngaphezulu.

Lapho beqeda nokunamathisela ngomthofu, izinsalela ecucuza kumele njalo zisuswe. Izimo zethu zihluke kakhulu kubalulekile unamathele omunye wemithetho main: umjikelezo Ukushisa akufanele kuhlale isikhathi eside kakhulu, futhi okweqile nhlobo ngaphandle inqubo. Ngaphezu kwalokho, kubalulekile ukuhlinzeka komoya ohlanzekile okwanele ukuvimbela eziyingozi kakhulu umzimba womuntu intuthu ehlanganisa cadmium umusi.

Ukuhambisana izincomo ngenhla ngeke kakhulu lula ukubulawa umsebenzi, ugcine isikhathi nosizo ukuze sifinyelele umphumela oyifunayo.
