Ukugcinwa nezinkinga ezivamile ze-multihead weigher

Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

Isikali esinezinhloko eziningi esisetshenziswa emishinini yokukala singesesigaba semishini yezinsimbi enembile kakhulu. Ukufakwa, ukusetshenziswa kanye nokugcinwa kumele kwenziwe ngokwemithethonqubo emiyalweni yokusebenzisa, ukuze kuqinisekiswe ukuphepha kwephaneli yezinsimbi, konke kujwayelekile, kunembile. Ngaphandle kwalokho, kungenzeka kakhulu ukuthi kubangele umonakalo kudeshibhodi noma kunciphise isikhathi sayo sokusebenza. 1. Ngokuvamile, iphaneli yezinsimbi kufanele ibekwe endaweni yemvelo enomoya ohlanzekile, owomile, wemvelo kanye nokushisa okufanele ukufakwa.

Iphaneli yezinsimbi kufanele ilungiswe futhi ingashukunyiswa njalo, ngaphandle kwalokho kungenzeka kakhulu ukuthi izintambo zangaphakathi zepulaki yamandla yekhebula lokuxhumana zizowa futhi zibangele ukwehluleka okuvamile. 2. Iningi lamamitha okulinganisa amandla okushintshana asebenzisa ama-volts angu-220 wamandla ashintshanayo, futhi ububanzi obuvumelekile be-voltage yokusebenza ngokuvamile bungama-volts angu-187 --- ama-volts angu-242. Ngemva kokushintsha umzila wokunikeza amandla okushintshana, khumbula ukukala ngokunembile ukuthi i-voltage esebenzayo iyahlangabezana yini nemithetho ngaphambi kokuxhuma amandla kuphaneli yezinsimbi.

Uma ugesi oshintshayo ongu-380 volt uxhunywe ngephutha kuphaneli yezinsimbi, kungenzeka ukuthi ubangele umonakalo. Izindawo lapho ugesi oshintshashintsha khona kakhulu kufanele zifakwe ugesi olawulwayo onezici ezinhle kakhulu ukuqinisekisa ukusetshenziswa okuvamile kwephaneli yezinsimbi. Akudingeki ukusebenzisa ipulaki yamandla efanayo enezimpawu zokuphazamiseka ezinamandla (njengezinjini, izinsimbi zikagesi, amashubhu e-fluorescent) ukuvimbela amanani olwazi angazinzile aboniswa kuphaneli yezinsimbi.

Amanye amaphaneli ezinsimbi anezinjongo ezimbili zamandla e-AC kanye ne-DC. Qaphela lapho ufaka izinhlelo zokusebenza zebhethri, ukuvuza kwebhethri kuzolimaza iphaneli yezinsimbi. Uma uhlelo lwamandla ebhethri elishajwayo lungasetshenziswa isikhathi eside, ibhethri elishajwayo kufanele lisuswe.

3. Imitha yokulinganisa enezinhloko eziningi yedivayisi yokumisa kufanele ixhunywe kusixhumi sentambo esihlukile nesihle kakhulu (ukumelana kwentambo yokumisa kungaphansi kwama-ohm angu-4, kanti intambo yedivayisi yokumisa kufanele ibe mfushane ngangokunokwenzeka). Isixhumi sentambo sinomsebenzi wezindlela ezimbili: asigcini nje ngokuba nomsebenzi wokugcina ukuphepha kwempilo yabasebenzi abasebenzayo, kodwa futhi sinomsebenzi oyinhloko wokulwa nokuphazamiseka, ongaqinisekisa ukuthi iphaneli yensimbi isebenza kahle. Intambo yokumisa ixhunywe ku-power plug yephaneli yensimbi. Intambo yokumisa ixhunywe kunethiwekhi yendawo yokuvikela yomphakathi ebuthakathaka, okungenzeka ukuthi ithinte ukunikezwa kwamandla okushintsha kwephaneli yensimbi, okubangela ukuthi inani lolwazi eliboniswe kuphaneli yensimbi lishintshe. Kufanele kugcinwe njalo ukuthi i-node yentambo yokumisa ayixhumeki kahle.

Ngenxa yokugqwala komoya kanye nokugqwala okubangelwa yi-node ngayinye ngemva kwesikhathi eside, iphaneli yezinsimbi izohluleka ngempela. 4. Ukwahlukaniswa kwe-sunscreen kufanele kuvimbele ilanga ekukhanyeni ku-chassis emnyama grey yephaneli yezinsimbi, ngaphandle kwalokho indawo yehhovisi yephaneli yezinsimbi ingonakala ngaphezu kwebanga lokushisa elilinganiselwe. 5. Ukumelana nomswakama Ngokuvamile, yize umswakama ozungezile wendawo yehhovisi lephaneli yezinsimbi ufinyelela ku-95%, kuyadingeka ukuthi ungabangeli ukuminyana.

Ikesi lepuleti lensimbi engagqwali eliyingqayizivele elinomphumela wokumelana nomswakama lingaphandle kwephaneli yezinsimbi. 6. Amakhemikhali alwa nokugqwala awakwazi ukungena ngaphakathi kwephaneli yezinsimbi, ngaphandle kwalokho azobangela ukugqwala ezingxenyeni zebhodi lesifunda le-pcb kanye nebhodi lesifunda le-pcb uqobo. Ngokuhamba kwesikhathi, iphaneli yezinsimbi ingase yonakale. Ngisho nephaneli yezinsimbi enomthelela wokulwa nokugqwala izoba nomphumela ofanayo uma uhlobo oluvaliwe lungavalwanga kahle.

7. Imishini yokulinganisa ukushaqeka okulwa nogesi ingeyesistimu yokuxhumanisa ehlanganisiwe, okulula kakhulu ukuhlaselwa umbani nokubhubhisa izingxenye. Isihluthulelo sokushaya kombani singena kwiphaneli yezinsimbi kusuka emazingeni amabili: kusukela kupulaki yamandla kanye nasepulatifomu yokulinganisa ngekhebula lesignali yedatha. Ngaphansi kwawo wonke amazinga okushisa ajwayelekile, abasebenzi abasebenzayo bangakwazi ukulawula inkinobho yamandla eyinhloko, kodwa uma kwenzeka ukushaya kombani okuseduze, qiniseka ukuthi ukhipha intambo yamandla yephaneli yezinsimbi kanye nepulaki yamandla yekhebula lokuxhumana lesikali.

Kungcono ukusebenzisa izindlela zokulwa nokushaqeka, njengokuthuthukisa isivikelo sokulwa nokushaqeka ku-loop yokulawula ukunikezwa kwamandla okushintsha iphaneli yezinsimbi. 8. Uma intambo ephilayo yokunikezwa kwamandla okushintsha engaphezu kwama-volt angu-220 ngokumelene nogesi obuthakathaka ishaya ngephutha ipulatifomu yesikali noma isebenzisa ipulatifomu yesikali njengentambo yomhlabathi, ukusebenza kwangempela kokushisela i-arc epulatifomu yesikali kungenzeka kulimaze iphaneli yezinsimbi. 9. Ukuhlanza Endaweni yemvelo yokukhiqiza izimboni, uma kukhona ukunqwabelana kothuli ephaneli yezinsimbi noma ukungcola kwemvelo, qiniseka ukuthi uyayisula ngethawula elimanzi lapho ugesi ucishiwe.

Kodwa qaphela ukuthi ungahlikihli ifasitela lolwazi lokubonisa ngezithako eziphilayo ezifana ne-ethanol, ezizothinta ukuhanjiswa kokukhanya futhi zibangele ukuthi ulwazi lokubonisa lufiphale. 10. I-Antistatic Uma iphaneli yezinsimbi yonakele, idinga ukulungiswa. Ukuze kusheshiswe kangcono isivinini sokudluliselwa kokujikeleza, ezinye izinkampani zithanda ukususa ibhodi le-PCB lephaneli yezinsimbi bese zisebenzisa ukulethwa okusheshayo okusheshayo, okubangela inkinga ye-anti-static.

Uma uthatha ibhodi le-PCB, kufanele ubambe amakhona amane ebhodi ngesandla, futhi ungathinti indawo ngezikhonkwane ze-field effect ngesandla. Ngenxa yalokho, kulula kakhulu ukuthi i-electrostatic induction yonakalise i-FET. Ibhodi le-PCB elihlakazekile kufanele lifakwe esikhwameni sokuvikela ngokushesha, futhi lingapakishwa ngamaphephandaba avamile ngaphandle kwesikhwama sokuvikela.

Uma ubeka ibhodi etafuleni elinesendlalelo esiphezulu sokuvikela, kungenzeka kakhulu ukuthi libhubhise ibhodi le-PCB. Uma uthola ibhodi le-PCB elilungisiwe, kumele liphinde lifakwe kuphaneli yezinsimbi, futhi unake i-anti-static. 11. Uma uthutha iphaneli yezinsimbi zokulwa nokudlidliza, kungcono ukuyifaka ebhokisini lezinkuni lokuqala, noma uthathe izinyathelo ezifanele zokulwa nokudlidliza.

12. Uhlobo olungaqhumi Uma iphaneli yezinsimbi isetshenziswa kusofthiwe yesistimu engaqhumi ehlanganisiwe noma ephephile ngokwemvelo, izidingo ezifanele zohlobo olungaqhumi kufanele zilandelwe. 13. Imisebenzi Yomsebenzi Imishini yokukala iyimishini yokukala enhle kakhulu, futhi kufanele isetshenziswe futhi inakekelwe ngobuchwepheshe ngabasebenzi abaqeqeshiwe. Kulesi sigaba, iningi lamatafula okulinganisa amakhanda amaningi asekelwe kuzilungiselelo eziyinhloko zamapharamitha kanye nokulinganiswa kusofthiwe yeselula ukuze kucaciswe indima nezici ze-elekthronikhi.

Uma le pharamitha eyinhloko isishintshiwe ngokungadingekile, kungenzeka ukuthi ibeke engcupheni ukunemba kanye nomsebenzi wokulinganisa (njengokungakopishi noma ukungabikho kokuxhumana, njll.). Ngakho-ke, kubaluleke kakhulu futhi ukucacisa imithwalo yemfanelo yomsebenzi efanele yabasebenzi bokusebenza kanye nabasebenzi bokulungisa.
