Ngabaizikali ze-craneizikali ezizenzekelayo okanye ezingezizo ezizenzekelayo?Lo mbuzo ukhangeleka ngathi uqale nge-R76 International Recommendation for Non-Automatic Weighing Instruments.Inqaku 3.9.1.2, elichaza "izikali ezixhonywe ngokukhululekileyo, njengezikali zokulenga okanye izikali zokumisa", zigqityiwe.
Ngapha koko, igama elithi “non-automatic scale” kwi-R76 Non-Automatic Weighing Scales lithi: isikali esifuna ungenelelo lomqhubi ngexesha lenkqubo yokukala ukuze kubonwe ukwamkeleka kwesiphumo sokuweyisha.Oku kulandelwa ngamanqaku amabini ongezelelweyo, Inqaku le-1: Ukuzimisela kokuvunywa kwesiphumo sokulinganisa kubandakanya umsebenzi womntu ngumqhubi ochaphazela umphumo wokulinganisa, umzekelo, izenzo ezithathwe xa ixabiso lizinzile okanye xa kulungiswa umthwalo wokulinganisa, kunye ukugqiba ukuba ukwamkela ixabiso eliboniweyo lesiphumo somlinganiso okanye ukuba ushicilelo luyafuneka.
Iinkqubo zokulinganisa i-non-automated zivumela umqhubi ukuba athathe inyathelo lokuphembelela umphumo wokulinganisa ukuba umphumo awumkelekanga (oko kukuthi, ukulungelelanisa umthwalo, ixabiso leyunithi, ukugqiba ukuba umthwalo uyamkeleka, njl.).QAPHELA 2: Xa kungenakwenzeka ukumisela ukuba isikali asiyonto izenzekelayo okanye iyazenzekela, iinkcazelo kwiiNgcebiso zaMazwe ngaMazwe ngeZikali zokuWela ezizenzekelayo (IRs) OIMLR50, R51, R61, R106, R107, R134 zikhethwa ngaphezu kwenkqubo ekwiNQAKU 1. ukwenza izigwebo.
Ukususela ngoko, imigangatho yemveliso ye-crane scales e-China, kunye neenkqubo zokulinganisa izikali ze-crane, zilungiselelwe ngokuhambelana nemimiselo ye-International Recommendation R76 ye-non-automatic scales.
(1) Izikali zeCrane zizixhobo ezivumela ukuveyishwa kwezinto ngelixa ziphakanyiswa, zigcina kungekuphela ixesha kunye nomsebenzi ofunekayo wokulinganisa, kodwa kunye nesithuba esithathwe yimisebenzi eyahlukeneyo yokulinganisa.Ngaphezu koko, kwiinkqubo ezininzi eziqhubekayo zokuvelisa, apho ubunzima buyimfuneko kwaye izikali ezisisigxina azikwazi ukusetyenziswa, izikali ze-crane ziluncedo kakhulu ekuphakamiseni nasekuthutheni izinto.Imveliso ephezulu, umgangatho wemveliso kunye nokhuseleko zidlala indima ebaluleke kakhulu.
Ukufunda ukuchaneka kwezikali ze-crane, impembelelo yendawo yokulinganisa kufuneka ithathelwe ingqalelo ngokupheleleyo.Ubume obuguquguqukayo ngexesha lokulinganisa, umoya, utshintsho kwi-acceleration ye-gravity, njl. njl. kuchaphazela iziphumo zokulinganisa;ukumiswa kwentloko ye-hook okanye imilinganiselo efanayo yempembelelo yoxinzelelo lwe-sling;ujingi lwempahla enobunzima bokuchaneka kwempembelelo ayinakungahoywa;ngokukodwa, iimpahla zokwenza intshukumo ye-conical pendulum xa impembelelo yexesha, elona naluphi na unyango lwezibalo lwendlela yokulinganisa eguqukayo ayinakusonjululwa.
(2) IiNgcebiso zaMazwe ngaMazwe kwiZixhobo zokuWeyisha ezingezizo eziSebenzayo, kwiSihlomelo A, sichaza kuphela iindlela zovavanyo lwezixhobo eziqhelekileyo ezingezizo ezizenzekelayo, kodwa azichazi naziphi na iindlela zokuvavanya izikali zokuxhoma.Xa i-National Weighing Instrument Measurement Committee ihlaziywe inkqubo yokuqinisekisa "I-Digital Indicator Scale" kwi-2016, yayiqwalasela iimpawu ezikhethekileyo zokuxhoma izikali.Ngoko ke, xa uhlaziywa i-JJG539 "I-Digital Indicator Scale" inkqubo yokulinganisa, iindlela zokuvavanya ukusebenza kwezikali zokuxhoma zongezwa ngokukodwa ngendlela ejoliswe kuyo.Nangona kunjalo, ezi zisahambelana neendlela zovavanyo kwimeko yokumisa, ukuphambuka kusetyenziso lwenyani lwemeko.
