Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

I-Multihead weigher iyinzwa yezinga lokudonsa uketshezi, evame kakhulu ekulinganisweni okunembile kwefomethi yedatha kanye nokulinganisa okunembile okuguquguqukayo. 1. Incazelo ye-multihead weigher icabangela umonakalo wokusheshisa amandla adonsela phansi (g) kanye nokugeleza komoya (f) kusetshenziswa ikheli elinemininingwane, futhi isekelwe ekuguquleni enye yezilinganiso ezinembile (isisindo) ibe enye Isilinganiso esinembile (ukuphuma) Inzwa yamandla yokulinganisa isisindo esinembile. 2. Izinto eziyisisekelo zesisindo se-multihead Izinto ze-polyurethane I-polyurethane elastomer (i-vibration isolator, umsebe ozwela kakhulu) iholela ekuguqulweni kwe-elastic ngaphansi kwesenzo samandla angaphandle, ukuze i-resistance strain gauge (idivayisi ye-electronic conversion conversion) enamathiselwe ebusweni bayo nayo iholele ekuguqulweni, ukumelana Ngemva kokuthi i-strain gauge iguquliwe, inani layo lokumelana lizobangela ushintsho (ukwanda noma ukwehla), bese lolu shintsho lokumelana luzoguqulwa lube yisignali yedatha yedivayisi ye-elekthronikhi ngesekethe yokulinganisa enembile, ngaleyo ndlela kuqedwe ukuguqulwa kwamandla angaphandle abe yisignali yedatha yedivayisi ye-elekthronikhi. yonke inqubo.

Kungabonakala ukuthi igeyiji yohlobo lokumelana, i-polyurethane elastomer kanye nesekethe yokuthola kuyizingxenye ezibalulekile eziningana ezingenakushoda ku-resistance judgment type multihead weigher. Lezi zici ezintathu zixoxwa kafushane ngezansi. 1. Igeyiji yohlobo lokumelana Igeyiji yohlobo lokumelana iyingxenye yegeyiji yohlobo lokumelana esakaza ucingo olushisayo imishini yezimboni odongeni noma ezintweni ezenziwe ngezinto eziphilayo.

Enye yemingcele yakhe ebalulekile eyisisekelo yinani lenkomba yokuqwashisa u-K. Lapho izinhlangothi zakhe ezimbili zibhekene namandla ka-F, kungenzeka ukuthi igobe futhi inwetshwe, okusho ukuthi ibangele ukuguquka. Uma sicabanga ukuthi igobe futhi inwetshwe, indawo yayo enqamulayo iyancipha, okungukuthi, irediyasi yayo yendilinga enqamulayo iyancipha.

I-resistivity elasticity coefficient (ushintsho oluhlobene lokumelana) lwegeyiji yokucindezeleka kokumelana kanye namandla okudonsa (ushintsho oluhlobene lobude) lwentambo yokushisa kuhlobene kahle nesilinganiso sokusebenza. Kumele kuqashelwe ukuthi ukucaciswa kwenani lenkomba yokuzwela inani le-K kuyipharamitha ephathwa futhi inqunywe yizici zezinto zokusetshenziswa zokwenza intambo yokushisa ehlanganisiwe yensimbi. Ayinalutho oluphathelene nokubonakala, ukucaciswa, imodeli kanye nokucaciswa kwegeyiji yokucindezeleka kokumelana. Inani ngokuvamile liyi-1.7—3.6 Ephakathi; okwesibili, inani le-K liyinani elingenakulinganiswa, okungukuthi, alinalo ubukhulu. Esisekelweni semishini, i-ΔL/L ibizwa ngokuthi isahlulelo, esichazwa njenge-ε, futhi isetshenziselwa ukubonisa ukuthi i-plasticity ngokuvamile ibonakala inkulu kakhulu, okuyinto engahambi kahle kakhulu, futhi ingxenye eyodwa kwesigidi sayo ivame ukusetshenziswa njengenkampani, echazwa njenge-με.

2. Izinto ze-polyurethane I-polyurethane elastomer Izinto ze-polyurethane I-polyurethane elastomer iyisakhi esinokubukeka okuhlukile. Inemisebenzi emibili. Ekuqaleni, inesibopho samandla angaphandle ahlushwa yi-multihead weigher, kanti amandla angaphandle abangela amandla okusabela ukuqinisekisa ukulingana okuhlobene; Isilinganiso sokucindezeleka kokumelana sinengqondo kakhulu ukufeza umsebenzi wansuku zonke wokuguqulwa kwesignali yedatha yedivayisi kagesi. 3. Isekethe yokuthola Umsebenzi wesekethe yokuthola ukuguqula ushintsho lokumelana kwegeji yokucindezeleka kokumelana lube umphumela we-voltage osebenzayo ojwayelekile.

Ngenxa yokuthi ibhuloho i-Wheatstone linezinzuzo eziningi, njengokuthi lingacindezela umonakalo wokushintsha kwezinga lokushisa, lingacindezela umonakalo wamandla ohlangothini, futhi lingaxazulula ubunzima bokunxephezela besisindo samakhanda amaningi kalula nangokushesha, ngakho-ke ibhuloho i-Wheatstone litholakale ku-weiger yamakhanda amaningi. Uhlu olubanzi lwezicelo. Ngenxa yokuzwela okuphezulu kwesekethe yeketanga eligcwele kanye namanye amabhuloho ezingalo, amapharamitha ayisisekelo engalo ngayinye afana, futhi izingozi ezahlukahlukene zingaxazululwa kalula.
