Ndimamba a cranemasikelo odzipangira okha kapena osangodzipangira okha?Funso ili likuwoneka kuti layamba ndi R76 International Recommendation for Non-Automatic Weighing Instruments.Ndime 3.9.1.2, ponena za "miyeso yopachikika kwaulere, monga miyeso yopachika kapena miyeso yoyimitsidwa", imatsirizidwa.
Komanso, mawu akuti "non-automatic scale" mu R76 Non-Automatic Weighing Scales amati: sikelo yomwe imafunika kulowererapo kwa woyendetsa panthawi yoyezera kuti adziwe kuvomerezeka kwa zotsatira zoyezera.Izi zimatsatiridwa ndi ndemanga ziwiri zowonjezera, Chidziwitso 1: Kutsimikiza kwa kuvomerezedwa kwa zotsatira zoyezera kumaphatikizapo zochitika zaumunthu ndi woyendetsa zomwe zimakhudza zotsatira zoyezera, mwachitsanzo, zochita zomwe zimatengedwa pamene mtengo wakhazikika kapena pamene mukukonzekera kulemera kwake, komanso kudziwa ngati kuvomereza mtengo womwe wawonedwa wazotsatira zoyezera kapena ngati kusindikiza kuli kofunikira.
Njira zoyezera zopanda makina zimalola wogwiritsa ntchito kuchitapo kanthu kuti akhudze zotsatira zoyezera ngati zotsatira zake sizikuvomerezeka (ie, kusintha katundu, mtengo wa unit, kudziwa ngati katunduyo ndi wovomerezeka, etc.).ZOYENERA KUDZIWA 2: Ngati n’kosatheka kudziwa ngati sikeloyo singodziwikiratu kapena yongodzichitira zokha, matanthauzo a mu International Recommendations for Automatic Weighing Scales (IRs) OIMLR50, R51, R61, R106, R107, R134 ndi amene amasankhidwa kuposa zimene zili mu NOTE 1. popanga maweruzo.
Kuyambira pamenepo, miyeso yamakina a masikelo a crane ku China, komanso njira zosinthira masikelo a crane, zakonzedwa molingana ndi zomwe International Recommendation R76 sikelo yodziyimira yokha.
(1) Masikelo a Crane ndi zida zomwe zimalola kuyeza kwa zinthu pamene zikunyamulidwa, kupulumutsa osati nthawi ndi ntchito yofunikira poyeza, komanso malo omwe amapangidwa ndi ntchito zosiyana zoyezera.Kuphatikiza apo, m'njira zambiri zopanga, pomwe kuyeza kumakhala kofunikira komanso masikelo okhazikika sangathe kugwiritsidwa ntchito, masikelo a crane ndi othandiza kwambiri pakukweza ndi kunyamula zinthu.Kupanga kwakukulu, khalidwe lazogulitsa ndi chitetezo zikuchita mbali yofunika kwambiri.
Kuti muphunzire kulondola kwa masikelo a crane, chikoka cha chilengedwe choyezera chiyenera kuganiziridwa mokwanira.Chilengedwe champhamvu panthawi yoyeza, mphepo, kusintha kwa mphamvu yokoka, etc. zimakhudza zotsatira zoyezera;kwa kuyimitsidwa kwa mutu wa mbedza kapena miyeso yofananira yamphamvu yamphamvu ya gulaye;kugwedezeka kwa katundu wolemera kulondola kwa zotsatira zake sikungathe kunyalanyazidwa;makamaka, katundu kuchita conical pendulum kayendedwe pamene zotsatira za nthawi, amene ali aliyense mwangwiro masamu mankhwala a mphamvu muyeso njira sangathe kuthetsedwa.
(2) Malangizo a Padziko Lonse a Zida Zosayezera Zodziwikiratu, mu Zakumapeto A, amangofotokoza njira zoyesera za zida zoyezera zomwe sizili zodziwikiratu zokha, koma sizifotokoza njira zilizonse zoyezera zoyezera masikelo.Pamene National Weighing Instrument Measurement Technical Committee idakonzanso ndondomeko yotsimikizira za "Digital Indicator Scale" mu 2016, inaganizira za makhalidwe apadera a masikelo olendewera.Choncho, pokonzanso ndondomeko ya JJG539 "Digital Indicator Scale" , njira zoyesera zogwiritsira ntchito masikelo olendewera zidawonjezedwa mwachindunji m'njira yolunjika.Komabe, izi zikugwirizanabe ndi njira zoyesera m'malo osasunthika, kupatuka pakugwiritsa ntchito zomwe zikuchitika.
