Isingeniso senqubo yokukhiqiza umkhiqizo we-RFMISO—i-vacuum brazing

1. Isimiso:

I-vacuum brazing isebenzisa amandla ashisayo ukushisisa i-solder endaweni yayo yokuncibilika futhi iyigcoke phezu kwezingxenye zensimbi ezizoxhunywa. Endaweni ye-vacuum, i-solder eshisayo iyancibilika futhi ingene ezindaweni zokuthintana zezingxenye zensimbi. Njengoba izinga lokushisa liyancipha, i-solder iyaqina futhi yakha uxhumano oluqinile. Imvelo ye-vacuum isiza ukunciphisa ukuba khona komoyampilo nokunye ukungcola, ngaleyo ndlela inikeze ikhwalithi engcono yokubhula.

2. Izisetshenziswa nezinqubo:

I-vacuum brazing ngokuvamile idinga ukusetshenziswa kwesithando somlilo noma okokusebenza kwe-vacuum brazing ukuze kuhlinzekwe ngendawo efanelekile yokushisisa nevacuum. Izithando zomlilo ngokuvamile zinezakhi ezifana nezinto zokushisisa, amagumbi evacuum, amaphampu evacuum, nezinhlelo zokulawula izinga lokushisa. Lapho wenza i-vacuum brazing, izingxenye zensimbi ziqale zihlanzwe futhi zilungiswe, bese zimbozwa ngensimbi yokugcwalisa. Okulandelayo, izingxenye zifakwa esithandweni se-vacuum futhi zishiswe ukuze i-solder incibilike futhi ingene ezindaweni zokuthintana. Ekugcineni, izinga lokushisa liyehla, i-solder iqina futhi uxhumano lwakhiwe.

3. I-Solder:

Ku-vacuum brazing, ukukhetha insimbi yokugcwalisa efanele kubalulekile ukuze uthole ukuxhumana okuhle. Ukukhethwa kwe-solder kuncike ezintweni ezifana nezinto zensimbi okufanele zihlanganiswe, izidingo zohlelo lokusebenza kanye nezinga lokushisa lokusebenza. Ama-solder ajwayelekile ahlanganisa isiliva-based, igolide-based, i-copper-based, i-nickel-based kanye namanye ama-alloys. I-Solder ivame ukusetshenziswa ngendlela ye-powder, i-ribbon noma i-coating.

4. Izindawo zokufaka izicelo:

Ubuchwepheshe be-vacuum brazing busetshenziswa kabanzi emikhakheni eminingi. Ivamise ukusetshenziswa ku-aerospace, okokusebenza kwe-elekthronikhi, emishinini yokubona, amashubhu evacuum, izinzwa, okokusebenza kwezokwelapha nezinkambu zamandla. I-vacuum brazing inika amandla ukuxhumeka okuphezulu, ukuqina okuphezulu nokuthembeka okuphezulu emazingeni okushisa aphezulu nezingcindezi eziphansi kakhulu, okuyenza ifanele izinhlelo zokusebenza ezidinga uxhumo lwekhwalithi ephezulu.

5. Izinzuzo

Ubuchwepheshe be-vacuum brazing bunezinzuzo ezilandelayo:

- Uxhumano Olunamandla Aphezulu: I-vacuum brazing inika amandla uxhumo lwensimbi oluqinile olunamandla amakhulu nokuvala.

- Ukucutshungulwa kwezinga lokushisa eliphansi: I-vacuum brazing ngokuvamile eyenziwa emazingeni okushisa aphansi kunezinye izindlela zokushisela, kunciphisa ubungozi bokonakala kwezinto kanye nezindawo ezithinteke ekushiseni.

- Ikhwalithi yokuxhumana enhle: Indawo ye-vacuum isiza ukunciphisa ukuba khona komoyampilo nokunye ukungcola, inikeze ikhwalithi engcono yokubhula.

Ngokuvamile, ubuchwepheshe be-vacuum brazing kuyindlela yokuxhumana enamandla amakhulu ehlanganisa izingxenye zensimbi ndawonye endaweni ye-vacuum. Isetshenziswa kabanzi emikhakheni eminingi yezimboni, inikeza ukuxhumana okuthembekile kanye nekhwalithi yokuxhumana enhle kakhulu.
