Kuchokera Kukhwima Mfundo | Lingaliro
Brazing ndi soldering ndi njira zogwirizanitsa zipangizo zofanana kapena zosiyana pogwiritsira ntchito zinthu zowonjezera. Zowonjezera zitsulo zimaphatikizapo kutsogolera, tini, mkuwa, siliva, nickel ndi alloys. Alloy yekha amatha kusungunuka ndikukhazikika mkati mwa njirazi kuti agwirizane ndi ntchito ya pulasitiki. Msuzi wothandizira amachotsedwa mu memphane ndi capillary action. Kuwombera kumayendetsedwa pansi pa 840 ° F (450 ° C) pamene kusungunula kumachitika pa kutentha pamwamba pa 840 ° F (450 ° C) mpaka 2100 ° F (1150 ° C).zolemba zazing'anga

Kupambana kwa njirazi kumadalira momwe makonzedwe a msonkhano akugwiritsidwira, chitsimikizo pakati pa malo omwe akuyenera kulumikizana, ukhondo, kuyendetsa kayendetsedwe kake ndi kusankha bwino zipangizo zofunika kuti pakhale njira yobwereza.

Ukhondo umapezeka makamaka mwa kuyambitsa kutuluka komwe kumaphimba ndi kusungunula dothi kapena ma oxides akuwathamangitsira ku gulu lolimba.

Ntchito zambiri tsopano zikuchitika m'malo olamulidwa ndi bulangeti lamagesi osakanikirana kapena kuphatikiza kwa mpweya / mphamvu yogwira ntchito kuti iteteze ntchitoyi ndikuchotsa kufunikira kwakubwera. Njirazi zatsimikiziridwa pazinthu zosiyanasiyana zakuthupi ndi magawo ena m'malo mwake kapena kuyamika ukadaulo wamoto wamlengalenga ndi nthawi yolondola - njira imodzi yoyendera.

Zida Zojambula Zojambulajambula
Brazing filler zitsulo zimabwera m'njira zosiyanasiyana, mawonekedwe, makulidwe ndi alloys malingana ndi momwe amagwiritsira ntchito. Ribbon, mphete zowonongeka, phala, waya ndi opanga mafinya ndizochepa chabe za mawonekedwe ndi kupanga mawonekedwe omwe angapezeke.Zida zowonjezeretsa

Chisankho chogwiritsa ntchito alloy ndi / kapena mawonekedwe makamaka zimadalira zomwe zipangizo zimaphatikiziridwa ndi makolo, malo opangira ntchito komanso malo omwe ntchito yomaliza imagwiritsidwa ntchito.

Kusintha Kumakhudza Mphamvu
Kutsekeka pakati pa malo oyandikana nawo kuti agwirizane kumadziŵitsa kuchuluka kwa bulloy alloy, capillary action / kulowa mu alloy ndipo kenako mphamvu yomaliza pamodzi. Chinthu chokwanira kwambiri cha ntchito zodzikongoletsera za siliva ndi 0.002 masentimita (0.050 mm) kufika ku 0.005 masentimita (0.127 mm) chilolezo chonse. Aluminiyamu ndiyake mainchesi 0.004 (0.102 mm) mpaka 0.006 masentimita (0.153 mm). Zowonjezera zazikulu kufika pa 0.015 masentimita (0.380 mm) kawirikawiri zimasowa chokwanira chokwanira kuti zikhale bwino bwino.

Brazing ndi mkuwa (pamwamba pa 1650 ° F / 900 ° C) amafuna kuti mgwirizanowo ukhale wochepa kwambiri ndipo nthawi zina zimakhala zoyenera kuti zikhale zoyenera kumadera otentha kuti zitsimikizidwe kuti zikhale zochepa zowonjezereka panthawi ya kutentha kwake.

Kuchepetsa Kutentha Kwambiri
Machitidwe operekera mpweya amapereka njira yabwino komanso yeniyeni yowonjezera dera lomwe lasankhidwa la msonkhano. Kuyenera kugwiritsidwa ntchito posankha mphamvu zamagetsi zowonjezera, mphamvu ya mphamvu (kilowatt yomwe ikugwiritsidwa ntchito pa mainchesi imodzi), nthawi yotentha, komanso kupanga chophimba chophimba kuti mupange kutentha kwakukulu mu mgwirizano wina.

Kutentha kwachitsulo ndikutentha kosagwirana ntchito pogwiritsa ntchito chiphunzitso cha transformer. Mphamvuyi ndi gwero la AC ku khola lopangidwira lomwe limakhala mphepo yoyamba ya transformer pamene gawo loti likhale lotentha ndilo lachiwiri la transformer. Chidutswa cha ntchito chimatentha ndi zipangizo zamagetsi kuti zikhale zowonongeka kwa magetsi mpaka pakali pano yomwe ikuyenda mu msonkhano.mfundo yofunikira ya kutentha kwa mpweya

Pakadutsa kupyolera mwa wothandizira magetsi (workpiece) amachititsa kutenthetsa monga momwe panopa ikutsutsana ndi kuyendayenda kwake. Kutayika uku kuli kochepa kwambiri pakalipano kuyendayenda kudzera mu aluminium, mkuwa ndi alloys. Zida zopanda feri zimafuna mphamvu zowonjezera kuposa mpweya wawo wa carbon.

Nthawi yotsatilayi imakhala ikuyenda pamwamba. Chiyanjano pakati pa maulendo a mawonekedwe osinthika ndi kuya kwake komwe kumadutsa gawolo amadziwika ngati kutanthauzira kwakukulu kwa Kutentha. Gawo linalake, mtundu wa zinthu ndi khoma makulidwe angakhale ndi zotsatira zowonjezera kutentha kuchokera pa zozamazo.
