Ukugcinwa kanye nezinkinga ezivamile ze-multihead weigher

Umbhali: Smartweigh–I-Multihead Weighter

Isikali se-multihead esisetshenziswa emshinini wokukala singesesigabeni semishini yokukala enembe kakhulu. Ukufakwa, ukusetshenziswa kanye nokugcinwa kufanele kwenziwe ngokuvumelana nemithethonqubo emiyalweni yokusetshenziswa, ukuze kuqinisekiswe ukuphepha kwephaneli yezinsimbi, konke kujwayelekile, kunembile. Uma kungenjalo, kungenzeka kakhulu kubangele umonakalo kudeshibhodi noma kunciphise ukuphila kwayo okusebenzisekayo. 1. Ngokuvamile, iphaneli yezinsimbi kufanele ibekwe endaweni yemvelo enomoya ohlanzekile, owomile, wemvelo kanye nezinga lokushisa elifanele ukuze lifakwe.

Iphaneli yensimbi kufanele ilungiswe futhi inganyakaziswa njalo, ngaphandle kwalokho kungenzeka kakhulu ukuthi izintambo zangaphakathi zepulaki yamandla ekhebula lokuxhumana zizowa futhi zibangele ukwehluleka okuvamile. 2. Iningi lamamitha esisindo esishintshayo sikagesi asebenzisa ama-volts angu-220 wamanje ashintshashintshayo, futhi ububanzi obuvumelekile bamandla kagesi okusebenza ngokuvamile bungama-volts angu-187 --- 242 volts. Ngemva kokushintsha umzila wokunikeza amandla okushintshayo, khumbula ukulinganisa ngokunembile ukuthi i-voltage yokusebenza iyahlangabezana yini nemithetho ngaphambi kokuxhuma amandla kuphaneli yensimbi.

Uma amandla okushintsha angu-380 volt exhunywe ngephutha kuphaneli yensimbi, kungenzeka adale umonakalo. Izindawo lapho i-voltage yokunikezwa kwamandla ishintshashintsha kakhulu kufanele ifakwe amandla alawulwayo anezici ezinhle kakhulu zokuqinisekisa ukusetshenziswa okuvamile kwephaneli yezinsimbi. Akudingekile ukusebenzisa ipulaki yamandla efanayo namasiginali okuphazamisa aqinile (njengamamotho, izinsimbi zikagesi, amashubhu e-fluorescent) ukuvimbela amanani olwazi angazinzile aboniswa kuphaneli yezinsimbi.

Amanye amaphaneli wezinsimbi anezinjongo ezimbili zamandla e-AC ne-DC. Qaphela lapho ufaka izinhlelo zokusebenza zebhethri, ukuvuza kwebhethri kuzolimaza iphaneli yezinsimbi. Uma uhlelo lokunikezela amandla ebhethri elishajekayo lungasetshenziswa isikhathi eside, ibhethri elishajekayo kufanele likhishwe.

3. Imitha ye-multihead weigher yedivayisi yokubeka phansi kufanele ixhunywe kusixhumi esihlukile futhi esihle kakhulu socingo (ukumelana nocingo oluphansi kungaphansi kwama-ohms angu-4, futhi ucingo lwedivayisi yokubeka phansi kufanele lube mfushane ngangokunokwenzeka). Isixhumi socingo sinomsebenzi wezindlela ezimbili: asinawo umsebenzi wokugcina ukuphepha kokuphila kwabasebenzi bangempela abasebenzayo, kodwa futhi sinomsebenzi obalulekile wokulwa nokuphazamiseka, ongaqinisekisa ukuthi iphaneli yensimbi isebenza kahle. Intambo yaphansi ixhunywe kupulaki yamandla yephaneli yensimbi. Intambo yaphansi ixhunywe kunethiwekhi yendawo yokuvikela yamanje ebuthakathaka, okungenzeka ithinte ukunikezwa kwamandla okushintshwa kwephaneli yensimbi, okubangele inani lolwazi eliboniswe kuphaneli yensimbi ukuthi liguquguquke. Kufanele kugcinwe njalo ukuthi i-wire node yomhlabathi ayixhumene kahle.

Ngenxa ye-oxidation yomoya nokugqwala okubangelwa i-node ngayinye ngemva kwesikhathi eside, iphaneli yensimbi izohluleka ngempela. 4. Ukuhlukaniswa kwesikrini selanga kufanele kuvimbele ilanga ekukhanyeni ku-chassis empunga-mnyama yephaneli yensimbi, ngaphandle kwalokho indawo yehhovisi yephaneli yensimbi ingase yonakaliswe ngaphezu kwebanga lokushisa elilinganiselwe. 5. Ukuvikela umswakama Ngokuvamile, nakuba umswakamo wendawo yehhovisi lephaneli yezinsimbi ufinyelela ku-95%, kuyadingeka ukuthi ungabangeli ukuminyana.

Ikesi lepuleti lensimbi engagqwali elihlukile elinomphumela wokuvikela umswakama lingaphandle kwephaneli yensimbi. 6. Amakhemikhali e-anti-corrosion kanye nokugqwala awakwazi ukungena ngaphakathi kwephaneli yensimbi, ngaphandle kwalokho kuzodala ukugqwala ezingxenyeni zebhodi lesifunda le-pcb kanye nebhodi lesifunda se-pcb ngokwayo. Ngokuhamba kwesikhathi, iphaneli yezinsimbi ingase yonakale. Ngisho nephaneli yensimbi ene-anti-corrosion effect izoba nomphumela ofanayo uma uhlobo oluvaliwe lungavalwanga ngokuqinile.

7. Imishini yokukala i-anti-electric shock ingokwesistimu ye-wiring edidiyelwe, okulula kakhulu ukuhlaselwa umbani nokubhubhisa izingxenye. Ukhiye wokushaywa kombani ungena kuphaneli yezinsimbi kusuka kumaleveli amabili: kusukela kupulaki yamandla kanye nokusuka endaweni yesisindo ngentambo yesiginali yedatha. Ngaphansi kwawo wonke amazinga okushisa avamile, izisebenzi zangempela ezisebenzayo zingakwazi ukulawula ukushintshwa kwamandla okuyinhloko, kodwa esimweni sokushaywa kombani oseduze, qiniseka ukuthi ukhipha intambo yamandla yephaneli yensimbi kanye nepulaki yamandla yekhebula lokuxhumana.

Kungcono kakhulu ukusebenzisa izindlela zokulwa nokushaqeka, njengokuthuthukisa isivikeli esinqanda ukuhlinzwa kuphaneli yensimbi eshintsha iluphu yokulawula ukunikezwa kwamandla. 8. Uma intambo ebukhoma yokushintsha kwamandla kagesi angaphezu kuka-220 volts ngokumelene namanje ebuthaka ishaya ngephutha iplathifomu yesikali noma isebenzisa inkundla yesikali njengocingo lwaphansi, ukusebenza kwangempela kokushisela kwe-arc endaweni yesikali kungenzeka kulimaze iphaneli yensimbi. 9. Ukuhlanza Endaweni yemvelo yokukhiqizwa kwezimboni, uma kukhona ukunqwabelana kothuli kuphaneli yensimbi noma ukungcola kwemvelo, qiniseka ukuthi uyayisula ngethawula elimanzi lapho amandla ecishiwe.

Kodwa qaphela ukuthi ungakhuhli iwindi lemininingwane yesibonisi ngezincibilikisi zemvelo ezifana ne-ethanol, okuzothinta ukudluliswa kokukhanya futhi kubangele ukuthi ulwazi lwesibonisi lufiphazwe. 10. I-Antistatic Uma iphaneli yensimbi yonakele, idinga ukulungiswa. Ukuze kusheshiswe kangcono isivinini sokuhamba nokubuya, ezinye izinkampani zithanda ukususa ibhodi le-PCB lephaneli yezinsimbi futhi zisebenzise ukulethwa okusheshisiwe, okubangela inkinga ye-anti-static.

Lapho uthatha ibhodi le-PCB, kufanele ubambe amakhona amane ebhodi ngesandla, futhi ungathinti indawo ngezikhonkwane zomphumela wenkundla ngesandla. Ngenxa yalokho, kulula kakhulu ukuthi i-electrostatic induction ilimaze i-FET. Ibhodi le-PCB elihlakaziwe kufanele lifakwe esikhwameni sokuzivikela ngokushesha, futhi lingapakishwa namaphephandaba avamile ngaphandle kwesikhwama sokuzivikela.

Uma ubeka ibhodi phezu kwetafula elinongqimba oluphezulu lokufakelwa, kungenzeka ukuthi licekele phansi ibhodi le-PCB. Lapho ithola ibhodi le-PCB elilungisiwe, kufanele liphinde lifakwe kuphaneli yezinsimbi, futhi linake i-anti-static. 11. Uma uthutha iphaneli yensimbi evimbela ukudlidliza, kungcono ukuyibeka ebhokisini lepulangwe lokuqala, noma uthathe izinyathelo ezifanele zokulwa nokudlidliza.

12. Uhlobo olungaqhumeki Uma iphaneli yensimbi isetshenziswa ohlelweni lwe-software lokuvikela ukuqhuma oluhlanganisiwe noma oluphephile, izidingo ezifanele zohlobo olungaqhumi kufanele zilandelwe. 13. Izibopho Zomsebenzi Izinto zokukala isisindo ziwumshini wokukala osezingeni eliphezulu kakhulu, futhi kufanele zisetshenziswe ngobungcweti futhi zinakekelwe abasebenzi abaqeqeshiwe. Kulesi sigaba, amathebula amaningi esikali se-multihead asekelwe kuzilungiselelo eziyinhloko zepharamitha kanye nokulinganiswa kwesofthiwe yeselula ukuze kucaciswe indima nezici ze-electronics.

Uma le pharamitha eyinhloko isishintshiwe ngokungafanele, ingahle ibeke engcupheni ukunemba kanye nomsebenzi wokukala (njengokungakopishi noma ukungabikho ukuxhumana, njll.). Ngakho-ke, kubaluleke kakhulu futhi ukucacisa izibopho zomsebenzi ezifanele zabasebenzi bangempela abasebenza kanye nabasebenzi abalungisayo.
