Kwakhona, isinyithi esijikelezileyo siya kuchaphazeleka bubushushu, ngoko ke uya kufumana i-warping ephambeneyo (efana ne-stainless) okanye indawo enkulu echatshazelwe bubushushu (njengentsimbi yealloyi). Iitotshi zokusika zicetyiswa nje ngentsimbi ethambileyo.
ubungqingqwa
Iitotshi zeOxyfuel zitya intsimbi engqindilili kwisidlo sakusasa. Ukuba uzama ukungena kwi-asi yentsimbi eyi-intshi eyi-4, ngoko ke itotshi yokusika sisixhobo sakho.
Ezona zinzima ngokwenene zinokunqumla kangangeemitha ezine zentsimbi eqinileyo. Enyanisweni, akunakwenzeka ukuba udibane nale nto rhoqo, kodwa awukwazi, akunjalo? Into ekufuneka uyikhumbule kukuba ungasika kwibhloko yenjini, ukuba yenziwe ngentsimbi hayi ialuminiyam.
Kuninzi lweeyunithi, nangona kunjalo, ungalindela ukunqumla kubukhulu obukhulu benyawo enye ukuba unombhobho wetotshi omkhulu. Incinci i-nozzle, i-kerf encinci, kwaye iyancipha i-material onokuyisika.
Iitotshi zePlasma azinakusikwa phantse njengemathiriyeli engqindilili. Eyona nto inzima kakhulu inokusika malunga ne-2-3 intshi ubukhulu, kodwa akunakwenzeka ukuba ufumane izandla zakho kwenye yazo. Amashishini asemgangathweni asike kakhulu malunga ne-1.5-intshi yemathiriyeli engqindilili, kunye noomatshini bokuzonwabisa bakholisa ukuphuma malunga ne-intshi enye.
isantya
Kwakhona, iplasma iyagqwesa. Kuba isebenza ngobushushu obuphambeneyo, ingumsiki okhawulezayo. Itotshi yokusika ayikho kwiligi efanayo nomatshini wokusika iplasma.
UkuPhatha
Umatshini wokusika amadangatye ngokuqinisekileyo ngowona uphathekayo ngokwemiqathango yokukwazi ukuwubophelela kwilori yakho kwaye unqumle itrektara embindini webala. Ungayisa naphi na apho unokuthwala khona.
I-plasma cutter (ngokubanzi) yiyunithi encinci, ngoko kulula ukuyiphatha, kodwa kufuneka ukwazi ukuyiplaga. Iiyunithi ezincinci zokuzilibazisa zihlala zinobunzima obujikeleze i-20-30 pounds. Ukuba usebenza ezivenkileni, akuyongxaki, kodwa ukuba usebenza efama, kunokucaphukisa ukuba akukho sokethi zeplagi ezikufutshane.
Izixhobo
Zombini iinkqubo zinezinto ezisetyenziswayo - iingcebiso ziya kuphelelwa kwaye kuya kubakho iindawo ezincinci ezitshintshileyo. Oku akuyondleko enkulu, nangona kunjalo.
Le yindawo enye apho iplasma iphumelela khona, nangona: kwi-oxyfuel, kufuneka uzalise iibhotile zakho zegesi, kodwa kwiplasma, ufuna kuphela umoya oxinanisiweyo.
I-Plasma isebenzisa umbane ofanelekileyo nangona kunjalo.
iinketho
Iitotshi zomlilo zithe ngqo, khetha nje ubungakanani obufanelekileyo bombhobho womsebenzi. Ekuphela kwento omele uqiniseke ngayo kukuba une-flashback arrestors efakiweyo ukuze ikhuseleke kwaye akukho nto ihamba phambili.
Kukho amagama ambalwa afanele ukwazi xa ujonge ukuthenga itotshi yeplasma. Nantsi isishwankathelo kunye nengcaciso yento abathetha ngayo.
Ukungafani
Lo ngumbuzo olayishiweyo – zombini iinkqubo zinokwenza izinto ezingenakuzenza omnye.
Nge-oxy-acetylene, iitotshi ezahlukeneyo (i-welding, ukusika, okanye i-rosebud) ikuvumela ukuba udibanise, ubushushu, ubuso obunzima, ukusika, i-solder, i-braze, idibanise, kunye ne-gouge. Ukusika, unqunyelwe kwintsimbi ethambileyo, kodwa unokuwelda iintsimbi ezininzi ngayo.
Kwiplasma, ungafumana ngokulula iiyunithi ezi-3-in-1 eziya kukuvumela ukuba usike, i-TIG, kunye ne-arc weld. Ngaphandle koko, nangona kunjalo, i-plasma cutter ingcono ukusika.
I-Pilot Arc
Olu lucingo olufutshane olugcina iplasma isebenza xa ingasondeli kwisixhobo sokusebenza.
Iyasebenza kwizicelo ezifana nokusebenza ngentsimbi eyandisiweyo okanye umnatha. Igcina umatshini esebenza rhoqo ukwenzela ukusika okuphazamisekileyo.
Ukuba ufuna nje ukufumana umsebenzi othile egaraji, awuyi kuyidinga le nto, kwaye awuyi kubona inzuzo enkulu ukuba usika kuphela isinyithi okanye uqhekeza imoto. Ukuba wenza umsebenzi omninzi wohlobo lwe-mesh, nangona kunjalo, iyayikhawulezisa inkqubo.
Rhoqo
Oku kubhekiselele kwi-high-frequency start of the plasma torch, kwaye iyafana newelder. Ngokusisiseko, umbane ohamba rhoqo uqalisa i-arc yomqhubi we-pilot ngokuqalisa i-high-frequency circuit ngokusebenzisa itotshi xa ucinezela i-trigger.
Oku kwenza indawo yokugqobhoza ibe ncinci, icoceke, kwaye ilula, kwaye iyasebenza kwizinto ezityebileyo.
Ngokubanzi, awufuni oku koomatshini bokuzonwabisa abasetyenziselwa isinyithi esicekethekileyo. Ukuba kukho nantoni na, isenzo esilungileyo kukugqobhoza i-material kancinane emgceni apho ufuna ukunqumla khona, emva koko itshayelele iplasma kumgca wokusika.
