Ezimbonini zesimanje ze-precision electronics, izimoto zamandla amasha, nezimboni zokwenziwa kwensimbi,I-Capacitor Welderszibalulekile ngenxa yezikhathi zazo zokukhipha ezimfushane kakhulu, izindawo zokushisa ezincane{0}ezithintekile, nomthelela ophansi kugridi yamandla. Kodwa-ke, opharetha abaningi bavame ukubhekana nezinselele ezifana ne-spatter eqinile, amandla okushisela angahambisani, noma ukugqokwa kwama-electrode okusheshayo. Isihluthulelo sokuthola imiphumela ye-welding ephelele sisekuhlanganiseni okujulile kanye nebhalansi eguquguqukayo phakathi kwemingcele emibili ebalulekile: yamanje (amandla) nengcindezi.
Lo mhlahlandlela uzohlinzeka ngohlaziyo oluningiliziwe lwendlela yokuthuthukisa ikhwalithi yokushisela nokusebenza kahle kokukhiqiza ngokusebenzisa ipharamitha yesayensi.
Umthetho Wamanje (Wamandla): Ukulawula Ngokunembile Ukukhishwa Kokushisa
Umgomo wokusebenza we-CD welder uhlanganisa ukugcina amandla kagesi ebhange le-capacitor nokukhulula umsinga omkhulu ngokushesha. Ngakho-ke, ngokuvamile sikala amandla ayo okukhiphayo ngokuya nge-voltage egciniwe (V) noma amandla okushisela (J). Ukulungiswa kwamanje akumele kucabangele ukujiya kwempahla kuphela kodwa nezinto ezibonakalayo, njengokuhamba kukagesi nendawo yokuncibilika.
Okwezinto ezisebenza kahle kakhulu (isb., ithusi, i-aluminium), lapho ukushisa kushabalalisa ngokushesha okukhulu, -ukufakwa kwamandla aphezulu kufanele kulethwe phakathi nesikhathi esifushane kakhulu (ngokujwayelekile 3-amamillisecond angu-10) ukuze kwakheke i-weld nugget esebenzayo. Ngokuphambene, ezintweni ezinokumelana nogesi okuphezulu (isb., insimbi engagqwali, ama-nickel alloys), ijika elikhipha amanzi elithambile kufanele lisetshenziswe ukuze kuvinjwe ukushisa okweqile kwendawo kanye nokusha.
| Uhlobo Lwezinto | Ubukhulu obujwayelekile (mm) |
Ibanga lamandla elinconyiwe (J) |
I-Reference Welding Current (A) | Ukucatshangelwa Kwenqubo |
| I-Pure Nickel/Nickel{0}}insimbi ecwecwe | 0.1 - 0.2 |
20 - 60 |
1500 - 3000 | Gxila ekuvimbeleni i-oxidation yendawo kanye nokusha-kudlule |
| Insimbi engagqwali (304/316) | 0.5-1.0 | 80-150 | 3000-5000 | Idinga ingcindezi ephezulu ukucindezela i-spatter |
| Ama-aluminium Alloys | 0.3 - 0.8 | 120 - 250 | 5000-8000 | Idinga izinga eliphezulu lamanje; ama-electrode adinga ukuhlanzwa njalo |
| Ithusi/Ithusi | 0.2-0.5 | 150-300 | 6000-10000 | Ama-electrode e-Tungsten copper kanye ne-flux{0}}esizwayo ngokushisela kuyanconywa |
Isu Lokulawula Ingcindezi: Ukusungula Ukumelana Nokuxhumana Okuzinzile
- I-Electrode pressure iwushintsho oluvame-olulinganiselwe kancane ekushiseleni ukumelana. Ku-CD welding, ingcindezi inquma ngokuqondile ukumelana nokuxhumana phakathi kwama-workpieces. Ngokomthetho ka-Joule ($Q=I^2Rt$), ukumelana nokuxhumana okuphezulu $R$ kudala ukushisa okwengeziwe. Ukucindezela okunganele kuholela ekumelana nokuthintana okuphezulu ngendlela engavamile, okubangela ukugcwala kwamandla ngokweqile phezulu kanye ne-spatter enzima. Ngokuphambene, ukucindezela okukhulu kubangela ukumelana nokuxhumana okuphansi kakhulu, okuholela ekushiseni okunganele kanye nokushisela okubandayo (ukuhlanganisa okunganele).
- Empeleni, umgomo "wokuqina-okuqinile{1}}okuqinile, okuthambile-ku-okumaphakathi" kufanele kulandelwe. Okwezinto eziqinile (isb,{7}insimbi yekhabhoni ephezulu, ama-alloys ekhopha), ukucindezela okukhulu (imvamisa phakathi kuka-1500N - 3000N) kuyadingeka ukuze kuqinisekiswe ukuthintana okusondelene. Okwezinto ezithambile (isb., i-aluminium, i-nickel emsulwa), ingcindezi kufanele ilawulwe phakathi kuka-500N - 1200N ukuze kugwenywe ukuwohloka okuphawulekayo komshini noma ukuhlehla kwengxenye yokusebenza. Ngaphezu kwalokho, ukulandela{16}okunamandla kubalulekile; umshini wokushisela kufanele ulondoloze ingcindezi ngokushesha njengoba izinto zincibilika ukuvimbela ukuxoshwa kwensimbi encibilikisiwe.
Ukuthuthukisa Okuvunyelanisiwe: Ukuthola "Ibhalansi Yegolide" Yamanje Nengcindezi
{0}}Ukushisela kwekhwalithi ephezulu akukhona nje ukunqwabelana kwamapharamitha angawodwana kodwa kuyinqubo lapho amandla amanje kanye nokucindezela kunxeshezelana. Lapho ulungisa ipharamitha eyodwa, kufanele uhlole ngesikhathi esifanayo umthelela kwenye.
- Indlela Yesinxephezelo Ephezulu Yamanje:Lapho kukhula amandla okushisela ama-workpieces ashubile, umfutho we-electrode kufanele ukhuliswe ngokulinganayo (imvamisa ngo-10% -15%) ukuze kuncishiswe ubungozi bokuphalaza okubangelwa ukwanda kwamandla.
- Indlela Yesinxephezelo Sokucindezela Okuphezulu:Ezimeni ezidinga ingcindezi ephezulu ukuze kuqinisekiswe ukuthi ucezu lokusebenza luyalingana-, ngenxa yokuncipha kokumelana nokuthintana, ukulahlekelwa ukushisa kufanele kunxeshezelwe ngokukhuphula i-voltage egciniwe noma ukwelula ubude be-pulse yokukhipha.
- Isimiso Sokulungisa Okukhuphukayo:Ngesikhathi sokuthuthukiswa kwenqubo, kunconywa ukuthi ulungise okuguquguqukayo okukodwa kuphela ngesikhathi, ngokunyuka kokulungiswa okulawulwa ngaphakathi kuka-5% -10%. Ukusebenza kwesethi yepharamitha ngayinye kufanele kuqinisekiswe ngokuhlolwa okuqinile nokuhlaziywa kwe-metallographic ukuze kutholwe iwindi lenqubo elilungile lezinto ezithile.
Ngo-Ukuxazulula Okujulile Kwezinkinga Zokushisela Okujwayelekile
Endaweni yokukhiqiza, ukubuka izenzakalo zokushisela kungakhomba ngokushesha ukuchezuka kwepharamitha. Ngezansi kunezixazululo ezichwepheshile zezinkinga ezijwayelekile okuhlangatshezwana nazo ekushiseleni ama-CD:
- I-Spatter Eqile (I-Spatter Esingaphezulu noma Esihlangana Nobuso): Lokhu ngokuvamile kubonisa "amandla eqile" noma "i-pressure lag." Kunconywa ukuthi uqale ukhuphule umfutho we-electrode ngo-500N - 800N. Uma inkinga iqhubeka, zama ukunciphisa amandla okushisela ngo-10%. Futhi, hlola ukuthi ithiphu le-electrode lingcolile yini, njengoba i-electrode engcolile yandisa kakhulu ukumelana nendawo.
- Amandla E-Weld Anganele (Ama-Cold Weld/Ukuntuleka Kwe-Fusion): Ibonakala ngokushisela{0}}okubukeka kahle okuhlukanisa kalula. Kulokhu, kancane kancane ukwandisa amandla we-welding, noma uhlole ukuthi ukucindezela kuphezulu kakhulu, okuholela ekushabalaleni kokushisa ngokweqile.
- I-Electrode Sticking kanye nokuba mnyama: Lokhu kuvame ukuphumela ekupholiseni okunganele kwe-electrode noma ukungahlanzeki kahle kwendawo yezinto. Ukunciphisa ingcindezi ngo-20% nokwandisa imvamisa yokugqoka ama-electrode, kuyilapho kuqinisekisa ukujikeleza kwamanzi okupholisa okufanele, kungandisa ngempumelelo impilo ye-electrode.
Imihlahlandlela Yokuqalisa kanye Nezincomo Zokumisa
- Ukuze kuqinisekiswe{0}}ikhwalithi yokushisela eqinile yesikhathi eside, abakhiqizi kufanele basungule uhlelo lokuphatha inqubo olubanzi. Okokuqala, ithebula lepharamitha elingcono kakhulu lenhlanganisela yezinto ezibonakalayo kufanele libhalwe phansi futhi lisetshenziswe njengezinga lokusetha labasebenzisi.
- Okwesibili, sebenzisa "isistimu-yokuqala yokuhlola," lapho ukuhlolwa kwamandla alimazayo kufanele kwenziwe ekuqaleni kweshifu ngayinye noma ngemva koshintsho lwento ebalulekile.
- Okokugcina, gcina njalo ukuma kwejiyomethri kwama-electrode, njengoba ngisho nezinguquko ezincane endaweni yokuxhumana ye-electrode zingaholela ekushintshashintsheni okuphawulekayo kokuminyana kwamanje, ngaleyo ndlela kuphazamise ibhalansi yepharamitha elungiselelwe.
Isiphetho
Ukwenza ngcono i-capacitor welder kuwumsebenzi wobunjiniyela besistimu. Ngokulawula kahle amandla amanje, ukusetha ngokwesayensi ukucindezela kwe-electrode, nokuqonda ngokujulile ubudlelwano babo bokusebenzisana, ungakwazi ukukhulisa ukusebenza kwemishini. Lokhu akuthuthukisi ngokuphawulekayo kuphela ukuvumelana kanye nobuqotho besakhiwo sokushisela kodwa futhi kunciphisa ngempumelelo amazinga e-scrap, okukhiqiza izinzuzo ezinkulu zezomnotho zebhizinisi lakho.
