Makina Ogulitsa Otentha a Copper ndi Brass Tube Induction Brazing
Mafotokozedwe Akatundu
Hongye yopangidwa Makina otsogola otsogola otsogola amakhazikika pakujowina kwapamwamba kwa machubu amkuwa ndi amkuwa (30 ° -60 ° angles) a HVAC ndi ma firiji. Pogwiritsa ntchito kutentha kwapang'onopang'ono (15-60kHz), imatulutsa mwachangu (masekondi 5-20), kutchingira komweko ndikuwongolera kutentha (± 3 ° C) kudzera pakuwunika kwa infrared. Makinawa amakhala ndi ma coil opangidwa mwamakonda kuti azigawira kutentha kofananira, zomwe zimapangitsa kuti siliva wopanda flux ndi kukhulupirika kolumikizana. Zokonzekera zokha zopangira ma 20-30 olowa / ola, zimapereka 50%+ kupulumutsa mphamvu poyerekeza ndi njira zachikhalidwe za nyali ndikuwonetsetsa kuti palibe kutayikira, kulumikizidwa kopanda okosijeni. Ndi abwino kwa ma U-bend, osinthira kutentha ndi machubu a condenser, njira yophatikizika, yamafakitale iyi imaphatikiza magwiridwe antchito ndi zotsatira zosasinthika, zapamwamba kwambiri pakufunsira kupanga machubu.
Kuchuluka kwa ntchito
Makina otsogola otsogolawa adapangidwa kuti azitha kujowina mwatsatanetsatane m'mafakitale angapo omwe amafunikira kulumikizana kodalirika, kwapamwamba kwambiri pamakina amkuwa ndi amkuwa. Kugwiritsa ntchito kwake kwakukulu kuli mu HVAC ndi ma firiji machitidwe, komwe amapambana pakuwotcha kwa U-bend, ma condenser coils, ndi zida zosinthira kutentha zomwe zimalumikizana molumikizana ndi 360 °. Makinawa amagwiranso ntchito pamapaipi amagetsi a mafakitale, kuphatikiza makina oziziritsira ndi mizere ya mpweya yomwe imagwiritsa ntchito zolumikizira zamkuwa. M'gawo lamagalimoto, ndi yabwino kwa brazing complex inclined chubing mu turbocharger intercoolers ndi makina owongolera mpweya. Makampani opanga zakudya ndi zakumwa amagwiritsa ntchito ukadaulo uwu pokhazikitsa mizere yaukhondo pomwe zolumikizira zamkuwa zosadukiza ndizofunikira. Ntchito zopangira magetsi zimaphatikizapo machubu a mkuwa omwe amawotchera m'majenereta obwezeretsa kutentha ndi zomera zoziziritsa kukhosi. Kapangidwe ka koyilo kozungulira kachitidwe kameneka (kusinthika kwa 30 ° -60 °) kumapangitsa kuti ikhale yofunikira kwambiri pamisonkhano yamachubu pamapangidwe a zombo ndi masitima apamtunda a HVAC. Ndi ntchito yake yopanda kusinthasintha komanso kuwongolera bwino kutentha, imakumana ndi milingo yokhazikika yamapaipi azachipatala a gasi ndi makina ozizira a semiconductor. Kugwirizana kwa makina amakina kumathandizira kupanga kwamphamvu kwambiri kwamachubu ophatikizika ndikusunga mawonekedwe obwerezabwereza pama masauzande ambiri.
Kusintha ndi Kuchita
Makina opangira zida zapaderawa amakhala ndi magetsi othamanga kwambiri a 15-40kW okhala ndi ukadaulo wa inverter wa IGBT, wokometsedwa kuti azitha kulumikizana zamkuwa ndi zamkuwa ndi zamkuwa m'makina a firiji. Makinawa amaphatikiza ma coil opangidwa ndi elliptical ndi ma helical induction induction omwe amafanana ndendende ndi evaporator, condenser, ndi ma compressor geometries, kuphatikiza ma U-bend ovuta komanso kulumikizana kwamutu. Dongosolo lozizira bwino lamadzi lophatikizana bwino limasunga kutentha koyenera kogwira ntchito panthawi yopanga mosalekeza. Mapangidwe amtundu wa modular amaphatikiza mawonekedwe ozungulira omwe ali ndi kusintha kwa 0-90 ° kopendekera kwa angled chubu brazing, kuphatikiza ndi mkono wa roboti woyendetsedwa ndi PLC woyendetsedwa ndi 6-axis kuti mugwirizane bwino. Dongosolo lophatikizika la argon gas purge limatsimikizira malo opanda okosidi a brazing pamagawo ovuta a refrigerant.
Dongosololi limakwaniritsa kuwongolera kwapadera kwamafuta kudzera pawiri-wavelength infrared pyrometers ndi ± 2 ° C kulondola kwa kutentha, kuyang'anira malo angapo olowa nthawi imodzi. Ma aligorivimu apamwamba a PID amasintha mphamvu zotulutsa mphamvu kuti zisunge kutentha koyenera pakati pa 600-800 ° C kutengera kapangidwe ka aloyi. Kutentha kofulumira kumafika pa kutentha kwa masekondi 8-15, ndi malo ocheperako omwe amakhudzidwa ndi kutentha amafikira 3-5mm kuchokera pamgwirizano, kuteteza kupotoza kwa kutentha kwa machubu opangidwa ndi mipanda yopyapyala. Kulondola kumeneku ndikofunikira makamaka pamalumikizidwe a ma capillary chubu mu evaporator komwe kutentha kwambiri kungayambitse kuletsa kuyenda.
Ubwino wolumikizana wokhazikika umatheka chifukwa cha kuthekera kwa makinawo kusunga zitsulo zofananira (AWS BCuP-5/BAg-8 alloys) zokhala ndi porosity pansi pa 0.5%. Kuyesa kowononga kumawulula mphamvu zolumikizirana zopitilira zitsulo zoyambira ndi 10-15%. Njirayi imachotsa zotsalira zomwe zitha kuwononga mabwalo afiriji, kukwaniritsa miyezo yachitetezo ya ASHRAE 15 ndi UL 207. Makina oyendera masomphenya odzichitira okha amatsimikizira kukwanira kwa mgwirizano ndi mapangidwe a minofu, kukwaniritsa zokolola zoyamba za 99.2% m'malo opangira.
Amapangidwa kuti azipanga kuchuluka kwambiri, makinawo amamaliza cholumikizira cha 3/8 "chubu-to-header mu masekondi 18-25, ndikupangitsa kuti kulumikizana kwa 140-180 pa ola limodzi. Kusintha kofulumira kwa ma coil kumachepetsa nthawi yokhazikitsira mpaka pansi pa mphindi 5 mukasinthana pakati pa magawo osiyanasiyana a geometri. Kugwiritsa ntchito mphamvu ndikotsika ndi 40-50% kuwongolera mphamvu, kutsika kwamphamvu kwa 40-50%. Kumanga kolimba kumathandizira kugwira ntchito kwa 24/7 ndi MTBF yopitilira maola 8,000, pomwe zidziwitso zolosera zokonzekera zimachepetsa kutsika kosakonzekera.
Pakugwiritsa ntchito kompresa, makinawa amaphatikizanso zida zapadera za hermetic terminal brazing yokhala ndi mbiri yotentha yoteteza kuwononga ma motor. Condenser coil brazing imagwiritsa ntchito ma coil amitundu yambiri polumikizana pamutu-to-chubu nthawi imodzi, kuchepetsa nthawi yozungulira ndi 30%. Kupanga kwa evaporator kumapindula ndi mphamvu ya micro-brazing yolumikizira machubu a capillary ang'onoang'ono ngati 1/8" OD. Masinthidwe onsewa akuphatikizapo makina otsuka mafiriji ogwirizana ndi nayitrogeni ndipo amakwaniritsa zofunikira za chitetezo cha ISO 5149 pazogwiritsa ntchito mufiriji.
