Munyori: Smartweigh– Huremu hwemisoro yakawanda

Kuvandudzwa kwetekinoroji kwekuongorora kwemetrological yerotary uye musimboti wayo wekutanga wekuyera huremu husina huremu 1. Mamiriro azvino enzira yekuongorora yekuyera yerotary mixer 1.1 Nzira yekuongorora yekuyera yerotary yekushandisa kwechinyakare ine nzira dzakawanda mukuongorora kwekuyera kwezvinhu zvakagadziriswa zvefiber zvakaita sezvinhu zvekushongedza, zviyo, mafuta, chikafu, kuchera, nezvimwewo, kana pakushandisa zvinonhuhwirira online. Dzakanyanya kushandiswa ndeidzi: zviyero zvebhandi remagetsi, maflowmeter eflushing plate, zviyero zvenyukireya, uye zviyero zvekudyisa disc. Iyi nzira yekuongorora yekuyera ine hunhu hwayo, asi zvipingamupinyi zvakakura kwazvo.

Tekinoroji yekugadzirisa yechiyero chebhandi remagetsi inounzwa zvakadzama. Matanho: Chikero chebhandi remagetsi chinobatanidza chiratidzo chedata remutoro chinowanikwa panzvimbo yese (chikamu chekuyera) chebhizinesi uye chiratidzo chedata chemuyero wekuchinja (chiyero chekumhanya kwebhandi rekufambisa) kuti uwane kukosha kwekuyerera kwese. Zvinangwa zvinochinjika. Cherechedza: Huwandu hwezvinhu zvinoburitswa hunochinjwa zvichienderana nehuwandu hwekumhanya kwebhandi rekutyaira rekudhonza nekudhonza. Mushure mekunge zvinhu zvakagadziriswa zvaumbwa uye zvakashongedzwa kuburikidza nechiteshi chekudyisa chechute yekudyisa, ukobvu hwazvo hunogadzikana uye hwakaenzana. Pasinei nehuwandu hwekumhanya kwebhandi, mutoro uri pabhandi rekutyaira unogara wakafanana. Kana tichienzanisa nedzimwe nzira dzekudyisa, nzira iyi ine mhedzisiro yakanaka yekuongorora metrological uye linearity.

1.2 Kushandiswa kwenzira yekuongorora metering inotenderera mumichina yekusanganisa inoenderera mberi Michina yekusanganisa inotenderera iripo inosanganisira: michina nemidziyo yekusanganisa ivhu yakagadzika simende, michina yekusanganisa concrete inotenderera, uye michina yekusanganisa bitumen inotenderera. Kana tichitaura nezvekuongorora kwemetrological, padanho rino, mhando iyi yemichina haigone kuverengerwa pamwe chete. Saka, nzira yekusanganisa inotenderera haifadzi vatengi vazhinji, inova imwe yezvikonzero zvakare.

Kuratidzwa kwesainzi kunogona kuratidza kuti tekinoroji yekusanganisa nekugadzirisa inosarudzwa nenzira mbiri idzi dzekuongorora zviyero ndiyo nzvimbo dzakakodzera, uye kushandiswa kwekusanganisa kwerotary hakufanirwe kukanganiswa nekuda kwemiganhu yetekinoroji iripo. Padanho rino, munyika medu, michina yekusanganisa yerotary inoyerwa nenzira yevhoriyamu kana chikero chebhandi remagetsi/chikero chinotenderera. Muma1970, tekinoroji yekusanganisa inoenderera mberi yakaunzwa kubva kuEurope kuti igadzire uye igadzire. Kusvika pari zvino, zvave zvakadaro, uye hapana shanduko yakaitika kubva pakutanga kusvika kumagumo. Kutaura zvazviri, nzira mbiri idzi dzekuongorora zviyero dzinogona kushandiswa muEurope nemazvo. Semuenzaniso, chikero chebhandi rekutumira cheZhongshan Smart weigh chine kurongeka kwe2%.
