Iimpawu zokusika:
Iiparamitha ezahlukeneyo ze-plasma arc cutting process zichaphazela ngokuthe ngqo ukuzinza, ukusika umgangatho kunye nomphumo wenkqubo yokusika.Eyonaumatshini wokusika i-plasma arc iinkcukacha zokusika zichazwe ngokufutshane ngolu hlobo lulandelayo:
1.I-voltage yokungabikho komthwalo kunye ne-arc ikholamu yombane Umbane wokusika umbane wePlasma kufuneka ube nomthamo omkhulu owaneleyo wokungathwali ukuze ukhokele i-arc ngokulula kwaye wenze i-plasma arc ivuthe ngokuzinzileyo.I-voltage engekho mthwalo ngokubanzi yi-120-600V, ngelixa i-voltage yekholomu ye-arc ngokuqhelekileyo isiqingatha sombane ongenamthwalo.Ukwandisa i-voltage yekholomu ye-arc kunokunyusa kakhulu amandla e-plasma arc, ngaloo ndlela kwandisa isantya sokusika kunye nokusika ubukhulu obukhulu beplate yensimbi.I-voltage yekholomu ye-arc idla ngokufezekiswa ngokulungelelanisa ukuhamba kwegesi kunye nokwandisa i-shrinkage yangaphakathi ye-electrode, kodwa i-voltage yekholomu ye-arc ayikwazi ukudlula i-65% ye-voltage engekho, ngaphandle koko i-plasma arc iya kuzinza.
2.Ukusika okwangoku Ukwandiswa kwangoku ukusika kunokunyusa amandla e-plasma arc, kodwa inqunyelwe ngumlinganiselo ophezulu ovumelekileyo wangoku, ngaphandle koko kuya kwenza ikholamu ye-arc ye-plasma ibe nzima, ububanzi bomthungo osikiweyo buyanda, kwaye ubomi be-electrode buyancipha.
3.Ukuhamba kwegesi Ukwandisa ukuhamba kwegesi akukwazi nje ukunyusa i-voltage yekholomu ye-arc, kodwa kwakhona kwandisa ukunyanzeliswa kwekholamu ye-arc kwaye wenze i-plasma arc amandla agxininiswe ngakumbi kwaye i-jet force inamandla, ukwenzela ukuba isantya sokusika kunye nomgangatho unokuphuculwa.Nangona kunjalo, ukuhamba kwegesi kukhulu kakhulu, kodwa kuya kwenza ikholomu ye-arc ibe mfutshane, ukulahlekelwa kobushushu kuyanda, kunye nekhono lokusika libuthathaka de inkqubo yokusika ayinakwenziwa ngokuqhelekileyo.
4.Ubungakanani be-electrode shrinkage Into ebizwa ngokuba yi-shrinkage yangaphakathi ibhekisela kumgama osuka kwi-electrode ukuya ekupheleni kombhobho wokusika, kwaye umgama ofanelekileyo unokwenza i-arc ixinzelelwe kakuhle kwi-nozzle yokusika, kwaye ufumane i-plasma arc ngamandla agxininisiweyo. kunye nobushushu obuphezulu bokusika okusebenzayo.Umgama omkhulu okanye omncinci kakhulu uya kubangela ukutshiswa okukhulu kwe-electrode, ukutshiswa kwe-cutter kunye nokunciphisa umthamo wokusika.Ubungakanani bokuncipha kwangaphakathi ngokuqhelekileyo yi-8-11mm.
5.Sika umbhobho wobude Ubude bombhobho osikiweyo bubhekiselele kumgama osuka ekupheleni kombhobho osikiweyo ukuya kumphezulu womsebenzi osikiweyo.Umgama ngokuqhelekileyo yi-4 ukuya kwi-10 mm.Kuyafana nokunciphisa kwangaphakathi kwe-electrode, umgama kufuneka ulungele ukunika umdlalo opheleleyo ekusebenzeni kakuhle kokusika kwe-arc ye-plasma, ngaphandle koko ukusika okusebenzayo kunye nomgangatho wokusika kuya kuncitshiswa okanye i-nozzle yokusika iya kutshisa.
6.Isantya sokusika Ezi zinto zingasentla zichaphazela ngokuthe ngqo isiphumo sokunyanzeliswa kwe-arc ye-plasma, oko kukuthi, ubushushu kunye noxinzelelo lwamandla e-plasma arc, kunye nobushushu obuphezulu kunye namandla aphezulu e-plasma arc inquma isantya sokusika, ngoko ke ezi zinto zingasentla zihlobene. kwisantya sokusika.Ngaphantsi kwesiseko sokuqinisekisa umgangatho wokusika, isantya sokusika kufuneka sandiswe kangangoko kunokwenzeka.Oku akugcini nje ukwandisa imveliso, kodwa kunciphisa inani le-deformation yecandelo elisikiweyo kunye nommandla ochaphazelekayo we-thermal yendawo yokusika.Ukuba isantya sokusika asifanelekanga, umphumo uguqulwa, kwaye i-slag enamathele iya kwanda kwaye umgangatho wokusika uya kuncipha.
Ukhuseleko loKhuseleko:
1.Inxalenye engezantsi yokusika i-plasma kufuneka imiselwe nge-sink, kwaye inxalenye yokusika kufuneka inqunywe ngaphantsi kwamanzi ngexesha lokusika ukuphepha ukutyhelwa komzimba womntu ngokuvelisa i-flue gas.
2.Gwema umbono othe ngqo we-plasma arc ngexesha lenkqubo yokusika i-arc yeplasma, kwaye unxibe iiglasi ezikhuselayo kunye nemaski yobuso ukunqanda ukutshisa kwamehlo kunyeisigcina-ntloko se-weldingnge arc.
3.Inani elikhulu leegesi ezinobuthi ziya kuveliswa ngexesha lenkqubo yokusika i-arc ye-plasma, efuna ukungena komoya kunye nokunxiba uthuli oluxutyiweyo oluninzi.imaski.
4.Kwinkqubo yokusika i-arc ye-plasma, kuyimfuneko ukunxiba iitawuli, iiglavu, iishethi zeenyawo kunye nezinye izixhobo zokukhusela zabasebenzi ukukhusela ukutshiswa kwesikhumba nge-splashing mars.5.Kwinkqubo yokusika i-plasma ye-arc, i-frequency ephezulu kunye ne-electromagnetic radiation eyenziwa yi-oscillator ephezulu-frequency iya kubangela umonakalo emzimbeni, kwaye abanye oogqirha bexesha elide bade babe neempawu zokungazali, nangona uluntu lwezonyango kunye neshishini lisangabonakali, kodwa basafuna ukwenza umsebenzi omhle wokhuseleko.
