Kukuziphi izimo lapho i-photovoltaic strip rolling mill ilungele ukusetshenziswa

       I-photovoltaic welding strip rolling mill iyisisetshenziswa esiyinhloko sokukhiqiza i-photovoltaic welding strip, ikakhulukazi esetshenziselwa ukucubungula amabhilidi engxubevange yethusi (njengethusi elingenawo umoya-mpilo kanye nethusi elipuletiwe ngothayela) libe yimicu eyisicaba enogqinsi olufanayo, indawo ebushelelezi, kanye nezinga le-micrometer ukunemba kobukhulu (okungukuthi. Izimo zokusetshenziswa kwayo zihambisana ngokuqinile nezidingo zokukhiqiza zemicu yokushisela ye-photovoltaic, egxile "kusixhumanisi sokukhiqiza i-welding strip ye-photovoltaic industry chain", engahlukaniswa ngezigaba ezilandelayo:

1,Isimo sohlelo lokusebenza: Ibhizinisi lokukhiqiza eliphrofeshinali lemicu yokushisela ye-photovoltaic

       Lesi yisimo esiyinhloko sokusetshenziswa kwe-photovoltaic welding strip rolling mill, emboza abakhiqizi bemicu yokushisela yezikali ezihlukene futhi bazivumelanisa nezidingo ezihlukahlukene zokukhiqiza:

       Amashabhu okukhiqiza esimanje amabhizinisi amakhulu okushisela amaribhoni e-photovoltaic (njenge-Wuxi Shangde, i-Suzhou Yubang, i-Zhejiang Jiaman, njll.) adinga ukuhlonyiswa ngesivinini esikhulu, ukunemba okuphezulu, kanye nezigayo zokushisela amaribhoni e-photovoltaic (iningi eliqhubekayo eliqhubekayo lokufeza imigqa yokukhiqiza ngaphezulu). Ezimweni ezinjalo, umshini wokugaya kufanele ube:

       Ikhono lokugoqa eliqhubekayo lokudlula okuningi (imvamisa ukudlula okungu-3-5), kuhlanganiswe nokutholwa kogqinsi ku-inthanethi kanye nesistimu yokulungisa okuzenzakalelayo, ukuze kuqinisekiswe ukuthi ukubekezelela ukushuba komugqa we-weld kulawulwa ngaphakathi kwe-± 0.005mm (ifanele izidingo zengxenye esebenza kahle kakhulu njenge-PERC ne-TOPCon);

       Kuxhunywe nemigqa elandelayo yokukhiqiza kathayela/isiliva kanye nemishini yokusonta, ulayini wokukhiqiza odidiyelwe "we-rolling cleaning coating winding" uyakhiwa, unciphisa ukungenelela okwenziwa ngesandla futhi uthuthukise ukusebenza kahle kokukhiqiza.

       Imikhiqizo ehambisanayo: Amateyipu okushisela wezingxenye ezivamile ze-single/polycrystalline (ubukhulu obungu-0.1-0.3mm, ububanzi obuyi-1.0-6.0mm), amateyipu okushisela ama-ultra-fine wezingxenye ezisebenza kahle kakhulu (ubukhulu obungu-0.08-0.15mm), kanye namatheyipu okushisela angavamile (amatheyiphu okushisela angama-triangular, ama-tape ayindilinga).

       Izimo zokukhiqiza ezenziwe ngezifiso ezincane nezimaphakathi zidinga izigayo eziguquguqukayo neziguquguqukayo ze-photovoltaic welding strip (ezifana nezigayo eziginqikayo nezishintshashintshayo) ezimbonini ezincane neziphakathi nendawo noma amabhizinisi agxile ocwaningweni olukhethekile lwe-welding strip kanye nentuthuko ukuze kuhlangatshezwane nezidingo ze-oda ezenziwe ngokwezifiso.

       Ingakwazi ukushintsha ngokushesha imininingwane yomqulu futhi ivumelane nokukhiqizwa kwemichilo yokushisela enobubanzi obuhlukene nobukhulu obuhlukahlukene (njengemicu emincane yokushisela engu-0.8mm ububanzi nemicu yokushisela ebanzi engu-8.0mm ububanzi);

       Sekela ukukhiqizwa kwesilingo seqoqo elincane (amashumi amakhilogremu kuya kumakhulu amakhilogremu iqoqo ngalinye), alungele ukwakhiwa kwemichilo yokushisela emisha (njengemicu yokushisela enezinga lokushisa eliphansi, imicu yokushisela ephezulu) noma ukwenza ama-oda amancane.

2,Isimo sohlelo lokusebenza esandisiwe: Amabhizinisi wemojula ye-Photovoltaic azakhela owawo umugqa wokukhiqiza we-welding strip

       Izinkampani eziphezulu zemojula ye-photovoltaic (ezifana ne-LONGi, i-JinkoSolar, i-Tianhe Solar, njll.) zizozakhela ama-workshops okukhiqiza ama-welding strip ukunciphisa izindleko ze-supply chain nokuqinisekisa ukuzinza kokunikezwa kwe-welding strip. Ngalesi sikhathi, i-photovoltaic welding strip rolling mill, njengemishini eyinhloko, idinga ukuzivumelanisa nesidingo "sokuxhumanisa ingxenye yokukhiqiza":

Vala isigcawu esisekela ububanzi

       Indawo yokusebenzela yokugaya iseduze nendawo yokusebenzela yomhlangano wengxenye, futhi imichilo yokushisela ekhiqiziwe ithuthwa ngokuqondile emgqeni wokukhiqiza wengxenye ngamabhande okuthutha noma amabhokisi okushintshana, ukunciphisa izixhumanisi zokulondoloza nezokuthutha kanye nokunciphisa ingozi ye-oxidation ebusweni bemicu yokushisela (ikakhulukazi imichilo yokushisela enamapulangwe esiliva anezidingo eziphezulu zendawo yokugcina impahla).

Qondanisa ngokunembile izimo zezidingo zengxenye

       Singakwazi ukwenza ngendlela oyifisayo usayizi womugqa wokushisela ngokohlobo lwamaseli ebhethri ezingxenyeni zethu (ezifana namaseli ebhethri angu-182mm no-210mm) kanye nenqubo yokushisela (izidingo zokujwayela umshini wokushisela okuzenzakalelayo), ukuze sigweme inkinga yokucaciswa okungafani kwemicu yokushisela ethengiwe (njengobubanzi be-welding strip engahambelani nesikhala somugqa wegridi kumaseli webhethri).

3,Isimo sohlelo lokusebenza olukhethekile: ukukhiqizwa kweribhoni eliphezulu eliphezulu/elikhethekile le-photovoltaic

       Ngemicu yokushisela ye-photovoltaic enenani eliphakeme elingeziwe nokusebenza okukhethekile, isigayo se-photovoltaic welding strip rolling siyadingeka ukuze kuhlangatshezwane nezidingo eziqinile zokucubungula:

Isimo sokukhiqiza se-ultra-fine/i-regular welding strips yezingxenye ezisebenza kahle

       Imichilo eyisicaba ye-Ultra (ukuqina ≤ 0.1mm) noma imichilo yokushisela engajwayelekile (njengezigaba ezingonxantathu kanye ne-trapezoidal) ezisetshenziswa ekukhiqizeni izingxenye ezisebenza kahle ezifana ne-TOPCon ne-HJT zidinga isigayo esigoqayo ukuthi sibe nokulawula okunembayo okuphezulu (ukubekezelelana kokuqina ± 0.003mm), ukugwema ama-Ra 1≤ ama-m ama-edge burrs endaweni ye-welding strip, futhi uqinisekise ukuqhutshwa nokunamathela ngesikhathi sokushisela.

Hlela izimo zokukhiqiza itheyiphu yokushisela ezindaweni ezikhethekile

       Khiqiza imichilo yokushisela engamelana nesimo sezulu (njengemicu yokushisela ekwazi ukumelana nokugqwala ephezulu) yokuhlanganiswa kwesakhiwo se-photovoltaic (BIPV) kanye nezitshalo zamandla e-photovoltaic zasolwandle. Umshini wokugaywa udinga ukuhlonyiswa ngezinqubo zokugoqa ezilwa nokuguquguquka (okufana nokugingqika kokuvikela i-nitrogen) ukuze kugwenywe ukuxutshwa kwe-oxidation ngaphezulu kwamapheshana ethusi ngesikhathi sokuginqika futhi kuqinisekiswe ukunamathela kwezingqimba ezinamathelayo ezilandelayo.

4,Isimo sokufaka isicelo: Ukugaywa kabusha komugqa wokushisela, ukuphinda kusetshenziswe kanye nokucutshungulwa

       Imboni ye-Photovoltaic amabhizinisi okugaywa kabusha kwezinsalela azophinde asebenzise imfucumfucu yokushisela ekhiqizwa ngesikhathi sokukhiqiza amamojula we-photovoltaic (njengokusika izinsalela nemikhiqizo enesici), futhi aphinde ayigingqe ngemishini yokugoqa i-photovoltaic welding strip (edinga ukususwa kwezingubo ezingaphezulu noma ukuncibilika kabusha kokusakazwa), ukucutshungulwa kube yizinto zokushisela ezinenani eliphansi le-rawta eliphansi noma i-copper efanelekile. imikhiqizo (njengamamojula amancane asabalalisiwe, amathoyizi e-photovoltaic) noma ezinye izinkambu zokucubungula ithusi, ukuze kuzuzwe ukugaywa kabusha kwezinsiza.

Izidingo ezibalulekile zokuzivumelanisa nezimo ukuze kusetshenziswe isimo

       Izidingo zokunemba: Ezimweni ezisebenza kahle zengxenye, ukulawulwa kokuqina kwezinga le-micrometer (± 0.003-0.005mm) kuyadingeka, kuyilapho ezimweni zengxenye evamile, kungaxegiswa ku-± 0.01mm;

       Ukuzijwayeza kwezinto: Lapho ugingqa ithusi elingenawo umoya-mpilo, umshini wokugaya udinga ukuba nokulawula okuhle kwe-ductility. Lapho ugoqa ithusi elicwebezelwe ngothayela, kuyadingeka ukugwema ukugoqana nokusebenzisa izinto ezikhethekile zokugaya (njengezigayo ze-tungsten carbide rolling);

       Ukulinganisa amandla: Izigayo ezigoqayo eziqhubekayo (ezinomthamo we-500-1000kg/ngosuku) ziyadingeka ekukhiqizeni okukhulu, kuyilapho izigayo eziginqikayo ngezikhathi ezithile (ezinomthamo wama-50-200kg/ngosuku) zingasetshenziselwa ukukhiqiza okuncane;

       Izidingo zemvelo: Indawo yokusebenzela yokukhiqiza kufanele ihlanzeke futhi yome (umswakama ≤ 60%) ukugwema uthuli oluthinta ikhwalithi ephezulu yomugqa wokushisela. Izindawo zokushisa eziphakeme kufanele zifakwe isistimu yokupholisa ngama-roller.
