Iliphi iphutha elivumelekile lokunemba kwesikali sokukala?

Ukuhlukaniswa kwamazinga okunemba ezikalini zokukala
Ukuhlukaniswa kwezinga lokunemba kwezikali zesisindo kunqunywa ngokusekelwe ezingeni lokunemba lazo. E-China, izinga lokunemba lezilinganiso zesisindo livame ukuhlukaniswa ngamaleveli amabili: ileveli yokunemba okuphakathi (izinga le-III) kanye neleveli yokunemba evamile (izinga le-IV). Okulandelayo ulwazi oluningiliziwe mayelana nokuhlukaniswa kwamazinga okunemba ezikalini zokukala:
1. Izinga lokunemba elimaphakathi (Izinga III): Leli izinga lokunemba elivame kakhulu lezikali zokukala. Kuleli zinga, inombolo yokuhlukanisa n yesikali sokukala imvamisa iphakathi kuka-2000 no-10000. Lokhu kusho ukuthi isisindo esincane esingahlukaniswa isikali sokukala singu-1/2000 kuya ku-1/10000 womthamo waso omkhulu wokukala. Isibonelo, isikali sokulinganisa esinomthamo omkhulu wokukala amathani ayi-100 singase sibe nesisindo sokulungiswa okungenani samakhilogremu angama-50 kuya ku-100 kilogram.
2. Izinga lokunemba elivamile (Izinga le-IV): Leli zinga lesikali sokukala ngokuvamile lisetshenziselwa izinjongo zezohwebo futhi alidingi ukunemba okuphezulu njengeleveli yokunemba okuphakathi. Kuleli zinga, inombolo yokuhlukanisa n yesikali sokukala ngokuvamile iphakathi kuka-1000 no-2000. Lokhu kusho ukuthi isisindo esincane esingasehlukanisa isikali singu-1/1000 kuya ku-1/2000 womthamo waso omkhulu wokukala.
Ukuhlukaniswa kwamazinga okunemba ezikalini kubalulekile ukuze kuqinisekiswe ukunemba kwazo ezimweni ezihlukene zohlelo lokusebenza. Lapho ukhetha isikali sokukala, abasebenzisi kufanele bakhethe ileveli yokunemba efanele ngokusekelwe ezidingweni zabo zangempela.
Ibanga likazwelonke elivumelekile lephutha lezikali zokukala
Njengethuluzi lokukala elibalulekile, ibhuloho lokukala lidlala indima ebalulekile ekukhiqizweni kwezimboni nasekuhwebeni kwezentengiselwano. Ukuze kuqinisekiswe ukunemba kwemiphumela yokukala, izwe selisungule imithethonqubo ecacile mayelana nebanga elivumelekile lephutha lezikali zokukala. Okulandelayo ulwazi olufanele ngephutha elivumelekile lezikali zokukala ngokusekelwe emiphumeleni yosesho yakamuva.
Amaphutha avumelekile ngokwemithetho kazwelonke ye-metrological
Ngokwemithetho kazwelonke ye-metrological, izinga lokunemba lezilinganiso zesisindo lisezingeni lesithathu, futhi iphutha elijwayelekile kufanele libe ngaphakathi ± 3 ‰, okubhekwa njengokujwayelekile. Lokhu kusho ukuthi uma ubukhulu besisindo somthamo wesikali singamathani ayi-100, iphutha eliphakeme elivumelekile ekusetshenzisweni okujwayelekile ngu-± 300 kilograms (okungukuthi ± 0.3%).
Izindlela zokuphatha amaphutha esikalini sesisindo
Uma usebenzisa isikali sokukala, kungase kube namaphutha ahlelekile, amaphutha angahleliwe, namaphutha amakhulu. Iphutha elihlelekile livela ikakhulukazi iphutha lesisindo eliqukethwe esikalini sokukala ngokwaso, futhi iphutha elingahleliwe lingase libe ngenxa yokwanda kwephutha elibangelwa ukusebenza kwesikhathi eside. Izindlela zokusingatha lawa maphutha zihlanganisa ukususa noma ukunxephezela amaphutha ahlelekile, kanye nokunciphisa noma ukuqeda amaphutha angahleliwe ngokulinganisa okuningi nokucubungula izibalo.
Amanothi avuliwe
Uma usebenzisa isikali sokukala, kubalulekile ukugwema ukulayisha ngokweqile ukuvimbela ukulimala kwenzwa futhi kuthinte ukunemba kwesisindo. Ngesikhathi esifanayo, izinto akufanele ziphonswe phansi ngokuqondile noma zehliswe ukusuka endaweni ephakeme, njengoba lokhu kungalimaza izinzwa zezikali. Ngaphezu kwalokho, isikali sokulinganisa akufanele sinyakaziswe ngokweqile ngesikhathi sokusetshenziswa, ngaphandle kwalokho sizothinta ukunemba kwedatha yesisindo futhi singathinta impilo yayo yesevisi.
Kafushane, ububanzi bephutha obuvunyelwe besikalo sokukala bunqunywa ngokusekelwe emithethweni kazwelonke ye-metrological kanye nokucaciswa kwesikali sokukala. Lapho kukhethwa futhi kusetshenziswa isikali sokukala, abasebenzisi kufanele basihlole ngokusekelwe ezidingweni zabo kanye nezidingo zokunemba, futhi banake ukusebenza okulungile ukuze kuncishiswe amaphutha.
