Momwe mungasankhire makina odulira makina a plasma?

Makina odulira plasmaNthawi zambiri amakhala ndi voteji yapamwamba yopanda katundu ndi voteji yogwira ntchito, ndipo kuwonjezeka kwa voteji kumatanthauza kuwonjezeka kwa arc enthalpy.Pamene kuonjezera enthalpy, kuchepetsa jet awiri ndi kuonjezera mlingo otaya mpweya kungathandize kuchepetsa liwiro ndi kudula khalidwe.Ma voltages apamwamba amafunikira mukamagwiritsa ntchito mpweya wokhala ndi mphamvu zambiri za ionization, monga nayitrogeni, haidrojeni kapena mpweya.Kodi nsonga ndi mfundo zotani posankha gasi?Tiyeni tione mwatsatanetsatane kusanthula gasi ndi akatswiri plasma kudula makina opanga.

Hydrogen imagwiritsidwa ntchito ngati gasi wothandiza wosakanikirana ndi mpweya wina, ndipo gasi H35 ndi umodzi mwamipweya yomwe ili ndi luso lamphamvu kwambiri lodulira plasma arc.Hydrojeni ikasakanizidwa ndi argon, gawo la gawo la haidrojeni nthawi zambiri limakhala 35%.Popeza kuti haidrojeni imatha kuwonjezera mphamvu ya arc, ndege ya hydrogen plasma imakhala ndi enthalpy yayikulu, ndipo luso lodula la plasma jet limakula kwambiri.

Mpweya wa okosijeni ukhoza kuonjezera liwiro la kudula zipangizo zachitsulo.Mukadula ndi mpweya, njira yodulira ndiyofanana kwambiri ndi makina odulira moto wa CNC.Kutentha kwapamwamba komanso mphamvu ya plasma arc imapangitsa kudula mofulumira, koma iyenera kugwiritsidwa ntchito pamodzi ndi ma electrode osagwirizana ndi okosijeni.Wonjezerani moyo wa ma electrode.

The slag opangidwa ndi kudula mpweya ndi nayitrogeni kudula ndi ofanana, chifukwa voliyumu zili nayitrogeni mu mlengalenga pafupifupi 78%, ndipo pali pafupifupi 21% mpweya mu mlengalenga, kotero liwiro kudula otsika mpweya zitsulo ndi mpweya kwambiri. pamwamba, ndipo Mpweya ndiye mpweya wogwiritsa ntchito ndalama zambiri, koma kudula ndi mpweya wokha kungayambitse mavuto monga kupachika kwa slag, kerf oxidation, ndi kuwonjezeka kwa nayitrogeni.Moyo wotsika wa maelekitirodi ndi ma nozzles udzakhudzanso magwiridwe antchito komanso kuchepetsa ndalama.

Pansi pa mphamvu yamagetsi yamagetsi, nitrogen plasma arc imakhala yokhazikika bwino komanso mphamvu ya jet yapamwamba kuposa argon.Mwachitsanzo, podula zitsulo zosapanga dzimbiri ndi ma alloys opangidwa ndi nickel, pamunsi pamunsi pamakhala slag, ndipo nayitrogeni ingagwiritsidwe ntchito yokha.Ukhozanso kusakanizidwa ndi mpweya wina.Nayitrojeni kapena mpweya nthawi zambiri amagwiritsidwa ntchito ngati gasi wogwira ntchito podula zodziwikiratu, ndipo mipweya iwiriyi yakhala mpweya wokhazikika pakudulira kothamanga kwa carbon steel.

Kuchita kwa argon kumakhala kokhazikika, ndipo sikumafanana ndi chitsulo chilichonse ngakhale kutentha kwambiri, ndipo nozzle ndi electrode zomwe zimagwiritsidwa ntchito zimakhala ndi moyo wautali wautumiki.Komabe, mphamvu ya argon plasma arc ndi yochepa, enthalpy siikwera, ndipo mphamvu yodulira imakhala yochepa.Poyerekeza ndi kudula kwa mpweya, makulidwe odulidwawo adzachepetsedwa ndi 25%.Kuphatikiza apo, kusamvana kwachitsulo chosungunuka kumakhala kwakukulu, komwe kuli pafupifupi 30% kuposa komwe kumakhala m'malo a nayitrogeni, kotero padzakhala zovuta zambiri zolendewera slag.Ngakhale kudula ndi mpweya wosakanikirana wa mpweya wina kumamatira ku slag.Chifukwa chake, argon yoyera sagwiritsidwa ntchito kawirikawiri yokha podula plasma.

MEN-LUCK, katswiri wopangazida zodulira laser, amapereka mitundu yonse ya mwatsatanetsatane makina odulira laser, makina kuwotcherera laser, ndi makina laser kuyeretsa katundu kwa nthawi yaitali, ndipo amapereka ntchito proofing pa nthawi yomweyo.Ngati muli ndi laser kudula processing zosowa, chonde omasuka kulankhula nafe!
