Isimiso ezisebenza we inverter Welding: incazelo, izifunda kanye namadivayisi

Traditional Welding imishini kanye transformers efanayo emikhulu yaphela kancane kancane. Kunalokho, manje kukhona icwecwe Welding inverters. Ziyakwazi kulula ukuyisebenzisa, bakwazi ngisho ingasetshenziswa ukuze uqale. Ukuze uthole ukuthi yini uhlobo idivayisi, kubalulekile ukuba sicabangele isakhiwo kanye isimiso yokusebenza inverter Welding.

mayelana design

Idivayisi ihlukile transformers bendabuko nokuningi ijwayelekile UWelder ngamunye. I inverter ezisebenza zamanje ukuguqulwa izinqubo zenzeka ngenye indlela. Lezi zinqubo iyokwenzeka ngezigaba ne-transformer encane, ogama Ubukhulu amaphakethe inkudlwana kagwayi. Omunye umehluko - i elawula uhlelo electronic. It ikuvumela ukuba lula inqubo Welding. uhlelo Siyabonga e-izinga emalungeni kwakhiwa. Nansi indlela umshini inverter Welding. Izibuyekezo yalesi imishini kule mihle kakhulu. Abantu abaningi ukuzisebenzisa ngenxa design compact nekhwalithi weld.

Isimiso jikelele wokusebenza

Ekuqaleni, imisinga okokufaka nge voltage ka 220 volts at a imvamisa variable odabula rectifier bese iguqulwe ibe njalo. Ngaphezu kwalokho, lamanje eshelelayo okokuhlunga. Ngokuvamile, kusetshenziswa njengendlela isikimu bendabuko esekelwe capacitors electrolytic. Ngokulandelayo, DC voltage nokudlula wamanje ngokusebenzisa modulator Semiconductor, lapho futhi iguqulwe ukuze AC, kodwa nge amaza ephakeme. Ngo onobuhle ezahlukene, lesi sibalo ezahlukene, kodwa ayidluli kwengu-100 kHz. I lwamanje ke kuyalungiswa futhi voltage futhi lehla nenani adingekayo kwensimbi weld. I yokusebenza Umgomo we inverter Welding esekelwe ephezulu imvamisa converters. Ukuba khona kwalawa izingxenye evumela ukusetshenziswa transformers ezincane, ngaleyo ndlela ziyancipha kakhulu iyunithi isisindo. Ngokwesibonelo, i inverter Welding umshini ukwazi ukunikezela samanje 160 amperes, transformer inesisindo kungekho abangaphezu kuka-250 amagremu. transformer wawuzoba isisindo ubuncane 18 kg ukufeza umphumela ofanayo usebenzisa ama-apharathasi ezivamile. Kungelula kakhulu.

I control unit - inzuzo eyinhloko inverter imishini Welding

A indima ebaluleke kakhulu ukusebenza kwalesi imishini edlala electronics. Ngenxa-ke lobudlelwano. Lokhu kusiza ukulawula ngokugcwele arc, ukulungisa noma uyigcine ezingeni efanele uma kunesidingo. I kancane ukuphambuka arc izici ngokushesha engafundwa microprocessor. Isimiso esinjalo wokusebenza umshini inverter Welding futhi nokuba ne-control unit electronic ukunikeza arc kagesi esiphezulu izici ezinzile. Lokhu ekugcineni kwandisa izinga Welding.

umdwebo olotshiwe

Esikhathini samanje rectifier kushintshana at a imvamisa 50 Hz futhi zinamandla 220 volts sidlula ibhuloho diode enamandla. zamanje Ripple ngokubonga imvamisa variable eshelelayo yokubakhona phezu kwengungu capacitors electrolytic. Ngo kokuhlinzwa, ibhuloho diode kukhonjelwe okweqile, ngakho diodes ukukhwezwa radiators. Ngaphezu kwalokho, inverter ifakwe fuse ezishisayo. Yena kwabangela uma diodes abangu sishisiswe 90 degrees. Thermal ivikela diodes. Eceleni kwebhuloho diode kungabonwa capacitors sasivumela eqinile jikelele. umthamo wabo kungaba isukela microfarads 140 kuya ku-800. Futhi kulesi sifunda zihlale izihlungi samanje, okuyinto ungavumeli e inqubo noma yikuphi ukuphazamiseka. Sesihlole yini Welding inverter isimiso. Ukushayela izindlela ezinye izakhi. Ake sihlole ngezansi.

Inverter: ukuthi kuyini

Ngqo inverter ngokwayo yakhiwe phezu ezimbili mosfetah. Lo mbuso transistors. Avame ishise kakhulu, ngakho ifakwe kurediyetha. izakhi Semiconductor okunjalo ukuxazulula inkinga ukushintsha imisinga edabula transformer ishayela. amaza Operating lapha kungaba idlule kHz latinkhulungwane letinyentana. Ngenxa yalokhu zamanje ekhiqizwa nge imvamisa onhlobonhlobo. I transistors kumele kube amelana voltage amathonsi. Abakhiqizi bafanele kuhlomisa kudivayisi nge izifunda ekhethekile zokuzivikela. Ngokuvamile, basuke bebahamba resistors wesifunda futhi capacitors. Bese kufika ku yesibili emazombezombe esinyathelweni phansi transformer. voltage wakhe encane - 70 volts. Kodwa wamanje kungaba 130-140 Amps.

I rectifier okukhipha

Ukuze akha okuqhubekayo okukhipha wamanje kanye voltage isicelo okunokwethenjelwa okukhipha rectifiers. Leli cebo kwenzekani ngesisekelo diodes double, okuyinto abe cathode ezivamile. Lezi zici isici ukusebenza okuphezulu, masinyane wavula avaliwe ngokushesha. Isikhathi Ukusabela kwama-diodes yisilinganiso esingu-50 nanoseconds. Lokhu isivinini kubaluleke kakhulu. Diodes kufanele sisebenze imisinga imvamisa eliphezulu, Semiconductor izakhi abavamile abakwazi ukubhekana ngokuphumelelayo lo msebenzi. Bamane anisuthi isivinini usuke. Endabeni ka ukulungisa, ngisho engazi Welding inverter kudivayisi, isimiso yokusebenza, lezi diodes yanconywa ukushintsha izakhi izici ezifanayo.

Design kanye ne-operation ye-computer

It is powered by umlamuli voltage, eyenzelwe 15 volts. Lezi zici efakwe radiators. Supply voltage ibhodi livela rectifier main. Lapho zinamandla sisetshenziswa, okokuqala capacitors icala. Voltage ngalesi sikhathi ukhula. Ukuze uvikeleke diode inhlangano esetshenziswa uhlelo eqine ngamandla resistors. Lapho capacitor usushajeke, umshini Welding uzoqala umsebenzi walo. Kuvalwa edluliselwe oxhumana nabo, kanye Resistor ngeke abahilelekile.

izingxenye engeziwe futhi izinhlelo

Sakhiwo isimiso yokusebenza inverter Welding kusikisela ukuba khona kwamanye amasistimu izingxenye ezihlinzeka ezifana ukusebenza kudivayisi okusezingeni eliphezulu. Ngakho, ungakhetha uhlelo lokulawula, kanye abashayeli. I element main lapha chip PWM isilawuli. Linikeza ukulawula isenzo transistors amandla. Futhi, idivayisi has ezihlukahlukene isilawuli nomthethonqubo wesifunda. Kulokhu, element eyinhloko transformer. Kuyadingeka ukulawula amandla nezinye izici elidlale transformer okukhiphayo. izenzo Welding inverter simiso kusho ukuba khona uhlelo ukuqapha voltage zamanje izici ekhishwa amapayipi supply. Le yunithi siqukethe tekusebenta izifunda amplifier ezisekelwe. Injongo eyinhloko uhlelo - ukuqala imodi Ukuvikelwa eziphuthumayo uma eziphuthumayo. Nayo iklanyelwe ukusebenza futhi ukuseviswa unit electronic.

imishini zokushisela ngoba TIG Welding nge argon

metal igesi engaxubani namakhemikhali Welding - ke ingenye yezindlela ethandwa kakhulu zokushisela inhlukano namuhla. Sebenza nge argon inikeza izinga okusezingeni emalungeni kulindeleke ukuthi baphothule kwemihlambi okugeza. Ngakho kungenzeka ukusebenza zonke izinsimbi, ngisho ne-aluminiyamu, magnesium, titanium futhi Alloys yabo. Umgomo we inverter Welding nge argon lutho ekhethekile kusukela inverter abavamile alihlukile. Umehluko omkhulu wukuthi hhayi kuphela wasebenzisa Welding umthombo wamandla, kodwa futhi sikaphalafini ekhethekile inqubo. TIG-Welding kuhilela Ukushisa unomphela kwesigaba sabasebenzi esebenzisa arc kagesi okuyinto adalwe refractory tungsten electrode. Abaningi ezithakazelisayo ukuze sibone indlela umshini inverter Welding yalolu hlobo. Ake sithole ukuthi kwakungani.

Ukwakhiwa Welding TIG-kudivayisi

Kuvele apharathasi ngoba TIG Welding liwumthombo zamanje kanye sikaphalafini ekhethekile. Umsuka kuyadingeka yokwenza i arc kagesi, futhi silondoloze ubuningi yayo nemingcele ezivamile. Inani elikhulu of izinsimbi kanye Alloys, okuyinto kungenziwa eziqhutshwa ngendlela, sebuningini ukulungiswa kusho. Namuhla-ke asetshenziselwa Semiconductor inverter amayunithi. Lokhu inverter Welding TIG. Umgomo we operation akahlukile kusukela inverter ezivamile, kodwa nomkhiqizo thuluzi kuhlanganiswe. zamanje ngqo isetshenziselwa ukusebenza ngensimbi engagqwali, Alloys zethusi. Variable futhi efanelekayo magnesium, i-aluminiyamu nezinye Alloys efanayo. ukusebenza lapho i imisinga ngakanye esetshenziselwa Welding izingxenye mncane. Futhi e isakhiwo sikaphalafini it has. Kuyini lokhu? Le idivayisi ekhethekile lapho isethi Tungsten electrode. It has a umlomo wombhobho lapho supply argon. Ngokungafani bendabuko Welding semiautomatic, a TIG Welding ithoshi egesi ukunikezela iyaqala phambi kokhela arc. Lokhu ugwema metal evutha.

isiphetho

engambi eqolo imishini kwenza kube nokwenzeka ukuba icabangisise ukuthenga umshini enjalo abendlu. Uma ungafunda indlela yokwenza ngokuqiniseka zisebenzisa leli thuluzi, ungakwazi ukuthola ngisho. Argon Welding namuhla baningi kakhulu. Ungakwazi ukuthenga oshibhile yasekhaya TIG-Welding inverter 180 s. Umgomo we operation yalolu phiko ikuvumela ukuba sisisebenzise inhlukano Welding imodi. Kuyinto isixazululo jikelele. izindleko zayo zokhahlamba kusuka ruble 13 kuya kwezingu-15. Iningi ezishibhile onobuhle Chinese angathengwa ngentengo ruble 6000. amadivaysi Professional abiza ruble angaba yizinkulungwane 50.
