Umgaqo esebenza ngayo inverter iwelding: inkcazelo, iziphaluka kunye nezixhobo

oomatshini welding Traditional kunye abaguquli ezifanayo emikhulu kancane. Endaweni yoko, kukho ngoku inverters welding compact. Kulula ukuyisebenzisa, abangela ukuba zisetyenziswe ukuze aqale. Ukuze ufumanise ukuba yeyiphi na uhlobo device, nto kubalulekile ukuqwalasela ubume kunye Umgaqo esebenza ngayo inverter welding.

malunga design

Le fowuni yohlukile abaguquli zemveli neziqhelekileyo ngakumbi kopi nganye. Iinkqubo yangoku conversion inverter ukusebenza kwenzeka ngenye indlela. Ezi nkqubo kwenzeka ngamanqanaba kunye sombane encinane, ogama imilinganiselo imiqulu lilikhulu kancinci ukutshaya. Enye mahluko - inkqubo yolawulo ngekhompyutha. It ikuvumela ukuba baququzelele inkqubo welding. omzimba Ngenxa e-umgangatho kwinkqubo kwakhiwa. Nantsi indlela umatshini inverter welding. Izimvo yale izixhobo kakhulu ezintle. Abantu abaninzi basebenzisa ngenxa yokuba uyilo compact nomgangatho weld.

Umgaqo iyonke yokusebenza

Ekuqaleni, input imisinga kunye lombane 220 volts qho eziguquguqukayo kwi aqukuqela rectifier aze atshintshelwe ibe njalo. Ukongezelela, umsinga mpuluswa yi lokucoca ulwelo. Amaxesha amaninzi, lisetyenziswa njengendlela scheme yemveli esekelwe capacitors electrolytic. Okulandelayo, DC ombane nokudlula ezikhoyo modulator semiconductor, apho kwakhona iguqulelwe kwi AC, kodwa phezulu. Xa imifuziselo ezahlukeneyo, eli nani ezahlukeneyo, kodwa ingadluli 100 kHz. Le yangoku ngoko kulungiswa kwaye ombane kwakhona kusithwa ixabiso efunekayo ukuze metal weld. Le yokusebenza Umgaqo inverter welding ngokusekelwe converters eziphakamileyo-rhoqo. Ubukho kula macandelo kuvumela ukusetyenziswa abaguquli ezincinane, ngaloo ndlela kunciphise kakhulu unit weight. Umzekelo, ukuba welding umatshini inverter awunako ukubonelela i yangoku amperes 160, nesiguquli kufuneka ubunzima grams hayi ngaphezulu kwe-250. transformer ukuba ubunzima ubuncinane 18 kg ukuze kufikelelwe isiphumo esifanayo usebenzisa izixhobo oluqhelekileyo. Kungelula kakhulu.

Iyunithi yolawulo - uncedo engundoqo koomatshini iwelding inverter

A indima ebaluleke kakhulu ekusebenzeni esi sixhobo odlala elektroniki. Ngenxa kuyo lobudlelwano. Oku kunceda ukuba ukulawula ngokupheleleyo arc, ukunyenyisa okanye ayigcine kwinqanaba elifanelekileyo xa kuyimfuneko. nangoko ukuphambuka arc iimpawu incinane ukufunda yi yavulel. Umgaqo ezinjalo yokusebenza ye kumatshini inverter ukuwelda kunye nokuba iyunithi yolawulo electronic ukunika electric arc neempawu ezizinzileyo eliphezulu. ekugqibeleni oku kwandisa umgangatho welding.

Idayagram

Kule yangoku ifildi rectifier kumaza-50 Hz kunye lombane 220 volts xa idlula ibhulorho diode enamandla. ngoku Ripples ngombulelo rhoqo bume mpuluswa ukuya khona kwakho isekethi capacitors electrolytic. Ukusebenza, lo ibhulorho diode ixhomekeke nobushushu, ngoko ke ilight enyusiweyo radiators. Ukongeza, i-inverter lixhotyiswe fuse thermal. Yena kwabangela ukuba ilight zaye lashushu degrees 90. Thermal uyagcina ilight. Ecaleni kwe bhulorho diode kunokubonwa capacitors kakuhle kakhulu lulonke. umthamo yabo zisukela microfarads 140 ukuya 800. Kwakhona kwisekethe basoloko amacebo akhoyo, ezo musa ukuvumela kule nkqubo naluphi na uphazamiseko. Siye sahlolisisa yintoni na iwelding inverter siseko. iindlela zokuqhuba ezinye izinto. Makhe sihlolisise apha ngezantsi.

Inverter: yintoni

Ngqo inverter ngokwayo yakhelwe phezu mosfetah ezimbini. Oku transistors amandla. Baya bakholisa ukuba kushushu kakhulu, ngoko mayixhotyiswe radiator. izinto semiconductor olunjalo ukusombulula ingxaki wayicima imisinga edlula transformer ukubetha. amaza yokuyisebenzisa apha lingaba ngaphezu amawaka aliqela kHz. Ngenxa yale langoku eyenziwe nge frequency variable. I transistors kufuneka zimelane amathontsi ombane. Abavelisi zixhobisa isixhobo kunye kwiisekethe ezikhethekileyo zokhuselo. Ngokufuthi, ziza kusetyenziswa resistors zeesekethe kunye capacitors. Emva koko, kuza ku ezizisekondari kwemicimbi kwinyathelo-phantsi sombane. ombane yakhe encinane - 70 volts. Kodwa langoku 130-140 Amps.

Le Imveliso rectifier

Ukuze ukwenza imveliso ekhoyo oluqhubekayo kunye ombane isicelo rectifiers output oluthembekileyo. Esi sikimu kwenzekayo ngokusekelwe ode kabini, apho kukho cathode eqhelekileyo. Ezi zinto isici phezulu-komsebenzi, ngoko nangoko zivuliwe ivalwe ngokukhawuleza. Ixesha abasabela ngayo ilight nama-50 nanoseconds. Le isantya kubaluleke kakhulu. Ama kufuneka basebenze kunye nemisinga aqhelelkileyo, izinto semiconductor eqhelekileyo ayikwazi ukumelana umsebenzi ololu hlobo. Nje abanalo isantya ziguquka ngokwaneleyo. Kwimeko ukulungiswa, uyamazi isixhobo iwelding inverter, isimiso ukusebenza, aba ilight ziyacetyiswa ukuba utshintshe kwi iziqalelo ezineempawu ezifanayo.

Uyilo kunye nokusebenza kwenkqubo yekhompyutha

Oku kuxhaswa yi-Regulator ombane, eyenzelwe volts-15. Ezi izinto efakwe kwi radiators. Supply ombane for ibhodi kuvela rectifier engundoqo. Xa lisetyenziswa ombane, okokuqala zonke capacitors icala. Le ombane kule mzuzu ukhula. Ukukhuselwa diode indibano kusetyenziswa Udweliso yetayitile kunye resistors ngamandla. Xa capacitor igcwaliswe ngokupheleleyo, umatshini welding iya kuqalisa umsebenzi wayo. Ivala nabo relay, hayi resistor ziza kuthatha inxaxheba kule nkqubo.

Amacandelo oloNgezelelweyo kunye neenkqubo

Ulwakhiwo nokusebenza Umgaqo le inverter welding kubonisa ubukho ezinye iinkqubo kunye namacandelo ezibonelela loo yokusebenza isixhobo eliphezulu. Ngoko ke, ungakhetha inkqubo yolawulo, kunye nabaqhubi. Into ephambili apha chip PWM umlawuli. Inika kolawulo yintshukumo transistors ngamandla. Kwakhona, ifowuni iye ezahlukeneyo zolawulo kunye ummiselo wesekethe. Kulo mzekelo, i element iphambili a sombane. Le ukuze ukulawula amandla kunye nezinye iimpawu zangoku emva imveliso transformer. izenzo segesi inverter mgaqo kuthetha ubukho inkqubo esweni ombane kunye zangoku iimpawu imveliso ye-mbane. Le yunithi iquka iisekethe ngombhobho-based zokusebenza. Eyona njongo iphambili yale nkqubo - qala imo ukhuselo olungxamisekileyo kwiimeko ezingxamisekileyo. Kwakhona iyilelwe esweni intsebenzo kunye serviceability kweyunithi elektroniki.

oomatshini welding for TIG ukuwelda kunye argon

metal negesi egalelwe welding - yenye yeendlela uthandwayo iwelding manual namhlanje. Sebenza argon inika amalungu ezikumgangatho ophezulu ngenxa ukugqiba Ukuqhela webhate. Ngoko ke kunokwenzeka ukuba ukusebenza yonke ngesinyithi, nkqu-aluminiyam, nemagnesium, titanium kunye aluminium zabo. Umgaqo inverter welding engenanto argon ekhethekileyo evela inverter eziqhelekileyo akukho ezahlukeneyo. Umahluko ephambili kukuba kuphela wasebenzisa ukuwelda umthombo wamandla, kodwa nesikopi ekhethekileyo kule nkqubo. TIG-welding ibandakanya ubushushu kwecandelo yokusebenza esisigxina esebenzisa i arc sombane eyenziwe yi-Tungsten electrode eliyinjubaqa. Abaninzi umdla ukubona indlela umatshini inverter welding yale hlobo. Makhe sibone.

welding Construction TIG-isixhobo

An izixhobo TIG welding ngumthombo lwangoku kwaye nesikopi okhethekileyo. Imvelaphi efunekayo ukuze odala arc sombane, kwaye kwakhona bagcine ubuninzi kweyesiqhelo parameters. Inani elikhulu zesinyithi kunye aluminiyamu, nto leyo esebenza ngendlela enjalo, ukuba nobuninzi hlengiso ithetha. Namhlanje lisetyenziswa beeyunithi semiconductor inverter. Le inverter welding TIG. Umgaqo yokusebenza ayahlukanga ukusuka inverter eqhelekileyo, kodwa zikhutshwa sixhobo zidityanisiwe. ngoku ngqo isetyenziselwa asebenze insimbi, aluminiyamu zezobhedu. Eliguqukayo nokufuya wemagniziyam, aluminiyam kunye nezinye aluminium efanayo. ukusebenza xa kwemisinga ngakanye esetyenziselwa ukuwelda iindawo ezibhityileyo. Kwakhona kwi isakhiwo kwisitovu ngayo. Yintoni na? Esi sisixhobo ekhethekileyo apho isethi Tungsten electrode. Kuye umlomo apho ubonelelo argon. Ngokungafaniyo yemveli iwelding okuzenzelekayo, a TIG iwelding itotshi igesi uqalisa phambi phemba i arc. Oku kuthintela ukuba metal ovuthayo.

isiphelo

iindleko olufikelelekayo lweso sixhobo kwenza kube lula ukucinga nzulu malunga uthenga umatshini olunjalo indlu. Ukuba ufunda ngokuzithemba ukusebenzisa isixhobo esinjalo, unako nokuba uzuze. Argon welding namhlanje ibango eliphezulu kakhulu. Unakho ukuthenga i engaxabisi yangaphakathi TIG-iwelding inverter 180 s. Umgaqo ukusebenza kwalo yunithi ikuvumela ukuba usebenzise kwi indlela iwelding manual. It is a isisombululo iphela. ixabiso layo isusela ukusuka engange-13 ukuya ku-15 amawaka. Uninzi imifuziselo cheap Chinese zinokuthengwa ngexabiso ka-6000 engange. izixhobo zobungcali zibiza malunga-50 amawaka engange.
