Izixhobo welding zombane: iintlobo, iimpawu, injongo

Electrowelded wabiza ndlela yokudala unxibelelwano abasisigxina, apho zokufudumeza kunye ukunyibilika intsimbi amalungu eziveliswa arc yombane. Ukwenza inkqubo nokudala unxulumano engaqukunjelwanga phakathi kwezakhi yesinyithi isicelo koomatshini iwelding. Kule meko kwakhona kuyenzeka ukuyinqumla isakhiwo zentsimbi okanye abahlule izinto.

ngezigaba

izixhobo Scope echazwe ixabiso iwelding zangoku:

• 150 A - nendlu oomatshini electric welding.
• Ukuya ku 250 A - semi.
• 250 A - umsebenzi.

Ekhaya arc umsebenzi zentsimbi kuyimfuneko kakhulu, ngenxa yokuba kukho rhoqo imfuneko ukunika uxhulumaniso esisigxina xa kufuneka ufakele ucingo, alungise umbhobho wamanzi unfrozen, weld iihenjisi esangweni okanye esangweni, yenza kwiindawo, yaye kakhulu ngakumbi. Iinkonzo ze abatyhidi zobungcali bagqiba iimpahla ezithengwe evenkileni imali eninzi. Advantageously ukufumana kopi arc kunye workpiece otyhidiweyo, ixabiso apho ifaniswa ukuthenga maxa wambi egqiba amanqaku. Nokuba bathi, ingakumbi uqoqosho luya ngayo kwixesha elizayo, xa zonke izixhobo eziyimfuneko zikhona kakade.

Icebo elula welding transformer enamandla ezinxulumene ngqo kwinethiwekhi. Yena a lot of okungalunganga: ubunzima enkulu kunye nobungakanani, ukusetyenziswa ngegunya, ukuntsonkotha yophuhliso yenkqubo welding. Kodwa kukho kwakhona okunokuzuzwa: elula, ukuthembeka ezizodwa, elula kunye nendleko eziphantsi.

kopi ongenamava kunzima ukufumana weld metal kwizinga eliphezulu usebenzisa sombane. Kuba ukusebenza okufanele kuyimfuneko ukuphuhlisa izakhono ezizodwa. Umsebenzi kwi ifildi ngoku kudala ubunzima ekugcineni i arc izinzile. Lover nzima ukukhetha indlela efanelekileyo yokusebenza.

Iimpawu transformers welding

Nesiguquli iqulathe primary jiko kunye downshift eziziisekondari. Eyokuqala liqhagamshelene womnatha, kwaye eyesibini isetyenziswa ukuwelda. ombane wayo 30-60 V. Welding 220 ilungele ukusetyenziswa ekhaya kunye mveliso basoloko onobuhle umbane ontlantlu-ntathu kwi 380 V. Le uxhulumaniso lusenziwa ngokusebenzisa umatshini usebenzisa umgca eyahlukileyo.

Ukukhetha le yunithi senziwa mpawu zilandelayo.

1. Segesi imida ulawulo lwangoku. amandla ziyatshintsheka kuthetha ukuba umntu uyakwazi ukukhetha iindlela zokusebenza lula kwaye utshintshe ubukhulu be electrode. Uphakamile ke ngoku eliphezulu, ingasetyenziswa ubukhulu ubungakanani electrode.
2. Ubukhulu be electrode. Kuba indlu sebenzisa 3mm aneleyo ukuphucula imveliso yenkqubo welding inxaxheba kucweyo okanye komasifundisane kufuneka 4-8 mm (lwangoku 120 ukuya 400 A). Ukuba ngaphantsi yangoku kwe umgangatho ofunekayo itywina kuya kuba phantsi.
3. kusele ombane. Ngokuba ukusetyenziswa lwasekhaya ukuba abaguquli 220 imifuziselo W. Industrial unako sinokubanamandla yi ekhethiweyo uthungelwano ontlantlu-ntathu. Izixhobo ezikhoyo ezinokuthi izakudityaniswa kubekanye zombini iindidi feed.
4. Segesi current. Ukususela ixabiso layo eliphezulu luxhomekeke electrode zinokusetyenziswa kuyo, kwakunye ithuba ukunciphisa isinyithi. Le eyesibini iparameter usoloko ecaciswe kwileyibhile. Kuba indlu sebenzisa imodeli abaguquli ekhethiweyo nosebenzela rated ka 160-200 A.
5. Rated ombane yokusebenza. Ubukhulu bale ombane ixhomekeke kwiziphumo jiko, okusuka ngentsimbi na omthuqwa.
6. imo okanye ratio umsebenzi ibonisa yingxenye ixesha nesiguquli ikwimo welding. lokubolekwa enamandla ukuze zifakwe ngaphakathi lonke shift (100%), kunye nokusetyenziswa ekhaya ngokwaneleyo-40%. Ukuba uthe waphuma-of-imida, ifowuni overheats nokuba yonakele.
7. ukusebenza sombane uthetha umlinganiselo phakathi kwamandla output walidla ngexesha ukuwelda. ngempumelelo enkulu imalunga 80%. Ukuba asezantsi, kuyimfuneko ukuba bakhangele omnye modeli.
8. Vula ombane yesekethe lula ukubonakala i arc yombane njengoko zanda. umbundu yokhuseleko umqhubi 80 V kunye alternating current and 100 V - apha rhoqo.

rectifiers welding

Zizixhobo kuvumela ukwenza i arc ozinzileyo ngexesha lokusebenza. Ukongeza sombane iqulathe iwelding rectifier imveliso selenium okanye lesilicon iiyunithi ukuba isicelo ukuya iintonga welding DC.

Makhwelo lula ukufunda ukuwelda kwindawo yangoku rhoqo. Ngaphezu koko, kusenokwenzeka ukuba weld kwesinyithi, aluminiyamu ubushushu-ukumelana kunye nesinyithi non-ayoni.

izixhobo welding zombane kufuneka ezingalunganga: iindleko eziphezulu, uvakalelo short-beesekethe kunye mbane iimvaba, kwakunye ilahleko amandla ngexesha lomsebenzi. Ngaphandle koku, le izixhobo ezisetyenziswa yi zombini amateurs kunye neengcali.

Iwelding rectifier balondoloza nabalulamileyo, kodwa ufuna ukungqinelana la manyathelo alandelayo:

• lihlole serviceability kunye nokuthembeka umbane;
• ukunqanda kokungena komisa ngaphandle nangaphakathi;
• bebetha umoya zixinaniswe ukususa uthuli.

Yintoni rectifier ukhetha?

Kangakanani na arc udibanisa iintsimbi, kuxhomekeke ngamandla, uphuphumalo kunye nomlinganiselo. Kubathandi umatshini ezifanelekileyo Telwin Umgangatho 220 AC / DC. Power 6 kW, ubuninzi yangoku - 160 A; ubunzima - 30 kg, ixabiso - ukuya ku-13 amawaka Hlikihla.. oomatshini Professional ukusetyenziswa lwasekhaya ezingachazwanga ngokuqhelekileyo kusetyenziswa ngenxa ixabiso eliphezulu (100 amawaka. Thambisani. Kwaye ngentla), phezulu ubunzima, ubungakanani kunye namandla.

inverters welding

Le fowuni ngumthombo ngoku, kokunikeza lula arcing kunye automatic nokugcina yokutsha yayo. isixhobo zombane welding inverter isebenza ngolu hlobo lulandelayo:

• lombane 220 V lisetyenziswa kwi rectifier, apho signal yahluzwa kwaye iguqulwe ibe ngoku ngqo;
• eyakhiwe eliphezulu-njalo current (inverter);
• voltage welding uvikivwa kwinqanaba (transformer);
• AC is kulungiseka.

Oyilwayo leesekethe linxulunyaniswa imfuneko ukunciphisa ubungakanani kunye ubunzima transformer ngenxa yokwanda kakhulu rhoqo. Ezona mpawu Imveliso ye isixhobo zixhaswa yi umlawuli we-elektroniki. Oku luncedo ephambili izixhobo, ungasebenzisa entsha imo kopi basandula kuqalisa ukuzisebenzisa. Ukuba transformer ukuwelda Xa sijonge iingcangcazela ombane kwi-network, oko akuthethi ukuzithwalisa imithwalo emikhulu inverter, kwaye okukhuthaza le arc ukuya othambileyo.

Ukuthembeka isixhobo lingaphantsi kunolo transformer, ngenxa yobukho kwisekethe elektroniki. Ibe ikwayise iso kumaqondo obushushu asezantsi nokufuma phezulu emoyeni. Le fowuni idala uphazamiseko magnetic ukuba kunciphisa imifuziselo ibiza kakhulu.

Iimpawu segesi usebenzisa inverter

Devices abe imisebenzi emithathu.

1. isiqalo Hot. Kweli xesha lokuqala ukunyuka yangoku kwaye ayifuni ubushushu electrode, njengoko in a sombane. Xa uqala i arc uba namandla ngakumbi, yaye welding kuphumelela.
2. Antizalipanie - yokusebenza ukunyuka ngoku xa kokudlulela i electrode. Isiphumo ikhefu fast, kwaye weld iparameters ngesiquphe abuyiselwe.
3. Atsho i arc. segesi lwangoku iparameters kwindawo antizalipaniya imo zibekiwe ukuze metal ukuba spray ngokugqithiseleyo.

kopi arc ekhaya kunye egadini

Kuba umphefumlo ekhethiweyo inverter zexabiso eliphantsi kunye umjikelo umsebenzi ngokupheleleyo ka-60%. Ngokufuthi asetyenziswa ziingcali, ngokuba umsebenzi kade kwaye nosebenzela yokusebenza encinane lesixhobo kujikwa rhoqo. Kubalulekile ukuba ombane mbane eqhelekileyo. Kulo mzekelo, isixhobo imveliso ekhethiweyo ku 160 A. iintsimbi 220 volts, imisinga ukuya ku-200 A efanelekileyo xa kukho yesi rhoqo le ombane mbane. 180 A phezulu kunokwenzeka ukuba weld i electrode sheets-4 mm ubukhulu kunye ne-5 mm zamafu.

Iindidi oomatshini iwelding kunye nabenzi

Wonke umntu uzama ukuthenga isixhobo ayibizi, kodwa ezineempawu elungileyo. Ezivela kwamanye amazwe weld elungileyo "Resanta" yaye "Interskol" apho nangamanani isusela ukususela nge-6 ukuya kwi-11 amawaka. Thambisani. Of yasekhaya kakuhle ukuzabalaza "Torus" yaye "Cedar" (ixabiso - 8-16 amawaka engange ..). Wokucoca ingabizi 6 amawaka. Hlikihla. ube ubunjani obuphantsi.

Amaxabiso emishini iwelding musa ibonise umgangatho imodeli. izixhobo Ufanele zikhethwa njengoko kwizibonakalisi ngqo: ubukho benkonzo, umyalelo umgangatho, ingxelo eyakhayo, kunye nabanye.

Segesi "Resanta Ais 220" uyakwazi ukudala ekhuselekileyo ngendibaniso iimveliso ze nenkcenkce nentsimbi shinyi, ngenxa yokuba banzi koluhlu ulawulo lwangoku. Le isixhobo akudali ingxaki ukunciphisa ombane lonikezelo-30% of par.

Inverter Umatshini electric welding "ukuvuleka isiZulu-205AP" - umfuziselo cheap Chinese-eyenziwe kakuhle ifanele ukusetyenziswa uveza kubomi bemihla ngemihla. Xa nokubuyekezwa, isixhobo Akusoloko ngapha ethembakeleyo, nangona kaninzi kukho imifuziselo ixesha elide isebenza ngaphandle breakdowns.

isiphelo

oomatshini welding zombane zikhethwa ngokungqinelana neemfuno. imodeli suit indlu ngumsebenzi ekhaya, nangenxa umsebenzi kufuneka ukhethe icebo ezibiza kakhulu, kunye kungenzeka umsebenzi esisigxina ngexesha shift. Kuba nasiphi na isixhobo kuyimfuneko ukujonga iindlela iwelding olululo nolondolozo ngokwemiyalelo.
