Chidziwitso china choyambira cha ukadaulo wodula laser

Mfundo yogwirira ntchito yodula laser

Kudula kwa laser kumakhala ndi jenereta ya laser yomwe imatulutsa kuwala kwa laser kwamphamvu kwambiri. Kenako kuwala kwa laser kudzayang'aniridwa ndi lenzi ndikupanga malo owunikira ang'onoang'ono kwambiri amphamvu kwambiri. Poyang'ana malo owunikira pamalo oyenera, zipangizozo zidzatenga mphamvu kuchokera ku kuwala kwa laser kenako n’kusungunuka, kusungunula, kuchotsa kapena kufika pamalo oyatsira moto. Kenako mpweya wothandizira wa kuthamanga kwambiri (CO2, Oxygen, Nayitrogeni) udzatulutsa zotsalira za zinyalala. Mutu wa laser umayendetsedwa ndi mota ya servo yomwe imayendetsedwa ndi pulogalamu ndipo imayenda motsatira njira yokonzedweratu pa zipangizozo kuti idule zidutswa zogwirira ntchito zamitundu yosiyanasiyana.

Magulu a majenereta a laser (magwero a laser)

Kuwala kungagawidwe m'magulu malinga ndi kuwala kofiira, kuwala kwa lalanje, kuwala kwachikasu, kuwala kobiriwira ndi zina zotero. Kungathe kuyamwa kapena kuwonetseredwa ndi zinthu. Kuwala kwa laser nakonso ndi kuwala. Ndipo kuwala kwa laser komwe kumakhala ndi kutalika kosiyanasiyana kwa mafunde kuli ndi mawonekedwe osiyanasiyana. Njira yopezera mphamvu ya jenereta ya laser yomwe ndi njira yosinthira magetsi kukhala laser imasankha kutalika kwa mafunde, mphamvu yotulutsa ndi kugwiritsa ntchito kwa laser. Ndipo njira yopezera mphamvu ikhoza kukhala mkhalidwe wa gasi, mkhalidwe wamadzimadzi ndi mkhalidwe wolimba.

1. Laser yodziwika bwino kwambiri ya gasi ndi CO2 laser;

2. Laser yodziwika bwino kwambiri ndi laser ya fiber, laser ya YAG, laser diode ndi laser ya ruby;

3. Laser yamadzimadzi imagwiritsa ntchito zakumwa zina monga zosungunulira zachilengedwe ngati njira yogwirira ntchito popanga kuwala kwa laser.

Zipangizo zosiyanasiyana zimayamwa kuwala kwa laser kwa mafunde osiyanasiyana. Chifukwa chake, jenereta ya laser iyenera kusankhidwa mosamala. Kwa makampani opanga magalimoto, laser yomwe imagwiritsidwa ntchito kwambiri ndi fiber laser.

Njira zogwirira ntchito za laser

Gwero la laser nthawi zambiri limakhala ndi njira zitatu zogwirira ntchito: mawonekedwe opitilira, mawonekedwe osinthira ndi mawonekedwe a pulse.

Pogwiritsa ntchito njira yopitilira, mphamvu yotulutsa ya laser imakhala yokhazikika. Izi zimapangitsa kuti kutentha komwe kumalowa muzinthuzo kukhale kofanana, kotero ndikoyenera kudula liwiro. Izi sizingongowonjezera magwiridwe antchito komanso zimawonjezera mphamvu ya malo omwe amakhudza kutentha.

Pogwiritsa ntchito modulation mode, mphamvu yotulutsa ya laser imafanana ndi ntchito ya liwiro lodulira. Imatha kusunga kutentha komwe kumalowa m'zinthuzo pamlingo wotsika pochepetsa mphamvu pamalo aliwonse kuti ipewe malire odulira osafanana. Popeza kuwongolera kwake kuli kovuta pang'ono, magwiridwe antchito si okwera kwambiri ndipo angagwiritsidwe ntchito kwa kanthawi kochepa.

Ma pulse mode angagawidwe m'ma pulse mode achizolowezi, super pulse mode ndi super-intense pulse mode. Koma kusiyana kwawo kwakukulu ndi kusiyana kwa mphamvu chabe. Ogwiritsa ntchito amatha kupanga chisankho kutengera mawonekedwe a zipangizo ndi kulondola kwa kapangidwe kake.

Mwachidule, laser nthawi zambiri imagwira ntchito motsatira njira yopitilira. Koma kuti mupeze mtundu wabwino kwambiri wodulira, pazida zina, ndikofunikira kusintha liwiro la chakudya, monga kufulumizitsa, kudula liwiro, ndi kuchedwa potembenuza. Chifukwa chake, motsatira njira yopitilira, sikokwanira kungochepetsa mphamvu. Mphamvu ya laser iyenera kusinthidwa posintha kugunda kwa mtima.

Kudula kwa laser komwe kumayikidwa ndi chizindikiro

Malinga ndi zofunikira zosiyanasiyana za malonda, ndikofunikira kupitiliza kusintha magawo pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito kuti mupeze magawo abwino kwambiri. Kulondola kwa malo odulira laser kumatha kufika pa 0.08mm ndipo kulondola kobwerezabwereza kwa malo kumatha kufika pa 0.03mm. Koma pazochitika zenizeni, kulekerera kochepa kuli ngati ±0.05mm pa kutsegula ndi ±0.2mm pa malo obowola.

Zipangizo zosiyanasiyana ndi makulidwe osiyanasiyana zimafuna mphamvu zosiyanasiyana pakusungunula. Chifukwa chake, mphamvu yotulutsa ya laser imasiyana. Pakupanga, eni mafakitale ayenera kulinganiza bwino liwiro lopanga ndi mtundu wake ndikusankha mphamvu yoyenera yotulutsa ndi liwiro lodulira. Chifukwa chake, malo odulira akhoza kukhala ndi mphamvu yoyenera ndipo zipangizozo zimatha kusungunuka bwino kwambiri.

Mphamvu ya laser yosinthira magetsi kukhala mphamvu ya laser ndi pafupifupi 30%-35%. Izi zikutanthauza kuti ndi mphamvu yolowera ya pafupifupi 4285W ~ 5000W, mphamvu yotulutsa ndi pafupifupi 1500W yokha. Kugwiritsa ntchito mphamvu yeniyeni yolowera ndi kwakukulu kwambiri kuposa mphamvu yotulutsa. Kupatula apo, malinga ndi lamulo losunga mphamvu, mphamvu zina zimasanduka kutentha, kotero ndikofunikira kuwonjezera choziziritsira madzi cha mafakitale .

S&A ndi kampani yodalirika yopanga ma chillers yomwe ili ndi zaka 19 zogwira ntchito mumakampani opanga ma laser. Ma chillers amadzi a mafakitale omwe amapanga ndi oyenera kuziziritsa mitundu yosiyanasiyana ya ma lasers. Laser ya fiber, CO2 laser, UV laser, ultrafast laser, laser diode, YAG laser, kungotchulapo ochepa. Ma chillers onse a S&A amapangidwa ndi zinthu zomwe zimayesedwa nthawi yayitali kuti zitsimikizire kuti zikugwira ntchito bwino kuti ogwiritsa ntchito athe kukhala otsimikiza kugwiritsa ntchito.
