Yintoni iPlasma Cutter?
A umsiki weplasma sisixhobo samandla esisebenzisa iteknoloji yokusika iplasma ukuze inyibilike kwaye ikhuphe i-incision ye-workpiece yesinyithi ngokusebenzisa ubushushu be-arc ye-plasma nge-argon, i-hydrogen, i-nitrogen, i-oksijini, umoya, umphunga wamanzi kunye nezinye iigesi ezixubeneyo ukwenza i-incision.
Isebenza Njani I-Plasma Cutter?
Abasiki beplasma banemilo eyahlukeneyo kunye nobukhulu. Kukho ifomathi enkulu ye-CNC ye-plasma yokusika iitafile ezisebenzisa iingalo zerobhothi ukulawula ukusika ngokuchanekileyo, kwaye kukwakho abasiki be-plasma abaphathwa ngesandla abasetyenziswa kwiindibano zocweyo zezandla. Kungakhathaliseki ubungakanani, bonke abasiki be-plasma basekelwe kumgaqo ofanayo, kunye noyilo lwesakhiwo luphantse lufane. Xa umatshini wokusika i-plasma usebenza, uthumela igesi ecinezelweyo njenge-nitrogen, i-argon okanye i-oxygen ngombhobho omncinci. I-electrode engafanelekanga ifakwe phakathi kombhobho. Xa amandla anikezelwa kwi-electrode engalunganga kunye noqhagamshelwano lokuvula umlomo wentsimbi, i-loop conductive yenziwa, kwaye i-spark yombane ephezulu yenziwa phakathi kwe-electrode kunye nesinyithi. Njengoko igesi ye-inert ihamba ngombhobho, i-spark yombane itshisa i-gas ide ifikelele kwisimo se-4 somcimbi. Le nkqubo yokusabela ivelisa umlambo we-plasma kunye nobushushu obumalunga ne-16,649 degrees Celsius kunye nesantya sokuhamba kweemitha ze-6,096 ngomzuzwana, onokukhawuleza ukuguqula isinyithi sibe yi-slag. Umsinga wombane uhamba ngeplasma ngokwayo. Ngethuba nje i-electrode iqhutywe ngokuqhubekayo kwaye i-plasma idibene nentsimbi, umjikelezo wokuvelisa i-arc uyaqhubeka. Ukuze uqinisekise lo mnxibelelwano ngelixa ugwema umonakalo obangelwa yi-oxidation kunye nezinye iimpawu ezingabonakaliyo zeplasma, umbhobho womshini wokusika uxhotyiswe enye isethi yemibhobho. Eli qela lemibhobho ngokuqhubekayo likhupha igesi yokukhusela ukukhusela indawo yokusika. Uxinzelelo lwegesi ekhuselayo lunokulawula ngokufanelekileyo i-radius ye-plasma ye-columnar. Indawo yokubeka i-plasma cutter kufuneka ibe kude nezixhobo zombane ezinkulu kunye neendawo ezinokuphazamiseka rhoqo kombane.
