Okokuqala: bheka ukubukeka kweshaja yebhethri
Bheka ukubukeka kweshaja yebhethri, noma igobolondo liqinile, noma intambo yamandla iwugqinsi
Okwesibili: bheka ukuthi ishaja yebhethri isiphumelele yini isitifiketi sekhwalithi
Bona ukuthi ishaja yebhethri inaso yini isitifiketi sekhwalithi esifanele, esifana ne-UL, inombolo yokuhlolwa yokufaneleka ye-Quality Supervision Bureau, njll. Hlola ukuze ubone ukuthi ingabe ikhona yini imikhiqizo emithathu, igama lomkhiqizi, imininingwane yokuxhumana, kanye nosuku lokwenziwa kwemoto kagesi. ishaja.Uma lezi zimo zihlangatshezwana nazo, khona-ke le shaja ingathengwa ngokuqiniseka.
Okwesithathu: khetha umenzi onamandla
Abakhiqizi beshaja yezimoto zikagesi abaneminyaka eminingi yomlando wokukhiqiza bavame ukuba nemiqondo yebhizinisi engcono, futhi isevisi yabo yangemuva kokuthengisa nayo iqinisekisiwe.Futhi manje kunabakhiqizi abaningi be-OEM emakethe abangakhiqizi imikhiqizo yabo, futhi abanandaba nekhwalithi yemikhiqizo yabo.Bamane balingise ngobumpumputhe futhi benze umgunyathi, beqhosha ngolwandle, futhi lapho izinga lokubuya seliphezulu, bazoshelela.Abathengi nabathengisi bangaba neshwa kuphela.Isibonelo ukuthi unaso yini isitifiketi sekhwalithi ye-ISO 9001 noma Cela isheke lenkampani yangaphandle esizeni.
Njengeshaja yebhethri enhle, ngaphezu kwezidingo ezimbili eziyisisekelo zokumelana nezinga lokushisa eliphezulu nokungavuzi, kufanele futhi ibe nale misebenzi elandelayo:
Ukuvikelwa kwesekethe emfushane, ukuvikelwa kwe-overcurrent, ukuvikelwa kwe-overvoltage, ukuvikelwa kwe-polarity reverse kanye nokuvikelwa kwe-overvoltage yesibili
