Intshayelelo
Kwintsimi ye-industrial welding,oomatshini bokuwelda bentekelelo yokugcina amandlazisetyenziswa kakhulu ekusetyenzweni kwesinyithi ngenxa yocikizeko oluphezulu kunye neempawu zogcino lwamandla-. Elinye lamacandelo abo aphambili - i-capacitors - idlala indima ephambili ekugcineni amandla kunye nokukhululwa kwangoko. Eli nqaku ligxininise kumsebenzi we-capacitor kumatshini we-welding yokugcina amandla, ukuhlalutya imigaqo yabo yokusebenza, iinzuzo, kunye nefuthe kumgangatho we-welding.
I. Capacitors: Ingundoqo yokuGcinwa kwamandla kunye nokukhululwa ngokukhawuleza
Ii-capacitors kumatshini wokuwelda wogcino lwamandla zihlawuliswa ngokulungiswa kwegridi, ukugcina amandla ombane ngohlobo lwamasimi ombane. Xa i-welding ifunwa, i-capacitors ikhupha ngokukhawuleza, iguqula amandla kwi-pulses ephezulu - yangoku (ngokuqhelekileyo igqitywe ngaphakathi kwe-milliseconds), idluliselwe nge-welding transformer ukuya kwindawo yokudibanisa i-workpiece, ivelisa amaqondo aphezulu okushisa ukunyibilika kwesinyithi. Xa kuthelekiswa neendlela zokuwelda zemveli, le nkqubo inezi mpawu zilandelayo:
1.Amandla agxininisiweyo: Ixesha lokukhupha i-Capacitor lifutshane kakhulu (0.003 -0.02 imizuzwana), kunye namandla agxininiswe kakhulu kwindawo ye-weld, ukunciphisa indawo echatshazelwe bubushushu kwaye inqanda ukuguquguquka kwesixhobo sokusebenza okanye ukuguquka kombala.
2.Amandla aphantsi, ukusebenza kakuhle okuphezulu: Amandla angoko nangoko atsalwa yi-capacitors ukusuka kwigridi aphantsi kakhulu kunezixhobo zendabuko, kunye nemithwalo yesigaba esinokulinganisela kunye nomgangatho ophezulu wamandla, ukunciphisa ukusetyenziswa kwamandla.
Umzekelo, xa iintsimbi ze-welding ezine-conductivity egqwesileyo ye-thermal efana ne-aluminium kunye nobhedu, ukukhutshwa ngokukhawuleza kwee-capacitors kunokulawula ngokuchanekileyo ukusabalalisa ubushushu, ukuthintela iingxaki ezingonelanga ze-welding ezibangelwa ukutshatyalaliswa kobushushu ngokukhawuleza.
II. Impembelelo yeeCapacitors kuMgangatho weWelding
I-1.Ukuphucula amandla e-Weld kunye nokuhambelana
Ngokuchithwa kwe-capacitor ezinzileyo, ukugcinwa kwamandla koomatshini be-welding welding ukuqinisekisa ukuhambelana kwangoku kunye neeparamitha zombane kwi-weld nganye. Umzekelo, xa welding intsimbi engatyiwa, i-capacitor voltage inokulungelelaniswa ngokuchanekileyo (efana ne-35-400V) ukuze ihambelane neemfuno zemathiriyeli yobunzima, ngaloo ndlela ifumana amandla e-weld afanayo.
2.Ukunciphisa i-Welding Defects
Ukukhutshwa kwe-Capacitor akukho ngxolo, intlantsi{0}isimahla, kwaye ayifuni izixhasi zangoku-ezinqandayo, zinqanda inkcitho yamandla kunye nengxaki ye-oxidation ye-workpiece ebangelwa kukunganyangeki kokufudumeza. Ngokomzekelo, xa udibanisa izinto ze-elektroniki ezichanekileyo, igalelo lokushisa eliphantsi le-capacitors linokuthintela ukutshiswa kwecandelo okanye umonakalo osebenzayo.
3.Ukuziqhelanisa neemeko zeWelding ezintsonkothileyo
Inkqubo ye-capacitor yogcino lwamandla omatshini wokuwelda ixhasa i-multi-ulawulo loxinzelelo lwenqanaba (ngaphambili{1}}uxinzelelo, uxinzelelo oluphambili, amanqanaba okugcina), kudityaniswe nohlengahlengiso lokukhutshwa kwexesha, inokuhlangabezana neemfuno zetsimbi ezingafaniyo (ezifana ne-aluminium + yobhedu) okanye i-welding yeplate encinci, ukuphucula ukuthembeka kwe-weld.
III. Ukugcinwa kwamandla kunye noZinzo oluluncedo lweCapacitor Design
1.Ukunciphisa iMpembelelo yeGridi
Izixhobo zemveli zokuwelda zixhomekeke kumbane oqhubekayo wegridi, obangela ngokulula ukuguquguquka kwamandla ombane; ngelixa ukugcinwa kwamandla oomatshini be-welding welding bahlawulisa ii-capacitors kuqala emva koko bakhuphe, abangenayo impembelelo kwigridi, ilungele ukusetyenziswa kwiindawo ezinobuncwane obuncinci bamandla.
2.Ukwandisa uBomi beZixhobo
Inkqubo yokugcina amandla e-capacitor ayifuni ukupholisa kwamanzi kwaye isebenzisa i-thyristor (SCR) i-non-contact switchs ukulawula ukutshaja kunye nokukhupha isekethe, ukunciphisa ukunxiba koomatshini kunye neendleko zokugcina. Umzekelo, ubomi bee-capacitors ezivela kumazwe angaphandle{2}zezixhobo zokuwelda zamandla aphezulu zinokufikelela kumashumi amawaka emijikelo, ngcono kakhulu kunezixhobo eziqhelekileyo zokuwelda.
3.Ukuziqhelanisa nokuGuquguquka kwiiMfuno ezahlukeneyo
Umthamo we-capacitor ohlengahlengiswayo (ofana ne-20,000-60,000 joules) kunye ne-voltage ivumela ugcino lwamandla koomatshini bokuwelda ukuba baphathe zombini i-welds ezincinci (ezifana neethebhu zebhetri) kunye nokuwelda ipleyiti eshinyeneyo (efana nezakhiwo zocango lwemoto).
IV. Iimeko zeSicelo kunye neeNdlela zexesha elizayo
Itekhnoloji yeCapacitor yogcino lwamandla omatshini wokuwelda isetyenziswe ngokubanzi kwimveliso yeemoto (izakhiwo zomzimba, iisistim zebrake), ishishini lombane (welding board board), i-aerospace (uqhagamshelo lwe-titanium alloy), kunye nezinye iinkalo. Ngophuhliso lwetekhnoloji yokuguqula itekhnoloji kunye nolawulo olukrelekrele, iinkqubo zokugcina amandla e-capacitor ziya kuphucula ngakumbi ukuchaneka kwe-welding kunye namanqanaba okuzenzekelayo, umzekelo, ukukhulisa i-capacitor discharge parameters ngokusebenzisa i-algorithms ye-AI ukufezekisa ukuveliswa kwemveliso esebenzayo.
Ukuqukumbela
Ii-capacitors kumatshini wokuwelda wogcino lwamandla azikho nje "intliziyo" yokugcina amandla kodwa kunye nesiqinisekiso somgangatho we-welding kunye nokusebenza kakuhle. Ngolawulo oluchanekileyo lwexesha lokukhutshwa, i-voltage, kunye noxinaniso lwamandla, inkqubo ye-capacitor ifezekisa ngokupheleleyo amandla e-weld, imbonakalo, kunye nokuzinza kwenkqubo. Kumashishini afuna ukuchaneka okuphezulu kunye nokusetyenziswa kwamandla aphantsi, ukuqonda ngokunzulu indima ye-capacitors kunye nokuqwalasela ngokufanelekileyo.oomatshini bokuwelda bentekelelo yokugcina amandlalinyathelo elingundoqo ekwandiseni ukhuphiswano lwemveliso.
