Umbhali: Smartweigh–Multihead Weighter
I-multihead weigher ngumatshini oguqula amandla e-kinetic ukusuka kwenye indlela ukuya kwenye. Ngokukodwa, i-multihead weigher yinzwa yamandla eguqula amandla omatshini (njengamandla okuxhasa, ukucutha, uxinzelelo lokusebenza okanye i-torque) kwiimpawu ze-elektroniki ezinokulinganiswa ngokuchanekileyo. Amandla oxinzelelo lwesignali yedatha atshintsha ngamandla oxinzelelo lwamandla okukhululwa.
Kukho iintlobo ezintathu ezisisiseko ze-multihead weigher ngokusekelwe kwisignali yedatha yemveliso: i-hydraulic, i-pneumatic kunye ne-resistance gauge yokumelana. Uhlobo oluqhelekileyo lwe-weigher olusetyenziswa kwimveliso yoshishino yi-multihead weigher kunye ne-strain eyakhelwe ngaphakathi. Igeyiji yokumelana ne-multihead weigher iquka umzimba wentsimbi eyomeleleyo (okanye "icandelo elityheli elastiki") elilungisa igeyiji yokuxhathisa.
Indlu ngokuqhelekileyo yenziwe nge-aluminiyam, i-carbon steel okanye ipleyiti yensimbi engenasici, eyenza ibe yomelele kakhulu kodwa i-ductile kakhulu. Indlela yokuziphatha yesilinganisi se-multihead ikhubaza kancinane xa isikali sisetyenziswa, kodwa sibuyela kwimo yaso yoqobo, ngaphandle kokuba ngumthwalo. Ukuze uphendule ngcono ekutshintsheni kobume bomzimba, igeji yokumelana ne-resistance gauge iphinda itshintshe inkangeleko yayo.
Oku kubangela ukuba inguqu yokumelana negage yoxinzelelo, enokuthi emva koko ilinganiswe ngokuchanekileyo njengotshintsho lombane osebenzayo. Ngenxa yokuba olo tshintsho kwimveliso luhambelana ngokufanelekileyo nobunzima bomnatha obukhutshiweyo, ubunzima be-net bento bunokumiselwa ukusuka kuguquko lombane osebenzayo. Sisebenza njani isikali seentloko ezininzi? Ukuphendula "Sisebenza njani isikali seentloko ezininzi?" Kufuneka uqale uqonde ukuba "Isebenza njani igeji yohlobo lokumelana?" I-resistance gauge ye-resistance gauge sisixhobo esilinganisa ngokuchanekileyo utshintsho lwe-resistor xa kukhululwa amandla.
Igaji yokuxhathisa eqhelekileyo iquka umnatha wocingo ocoleke kakhulu wefoyile, ebekwe kwipatheni yegridi, ebangela ukuba isixhathisi socingo siguquke xa amandla oxinzelelo ekhutshwa ecaleni kweasi enye. Kukho iintlobo ngeentlobo zeegeji zokuxhathisa ukukhetha kuzo: I-Linear resistance gauge gauge: Intambo yamandla edityaniswe ngasemva kwi-resistance gauge yokuxhathisa ihambelana nomda we-resistance gauge yokumelana. Oku kusetyenziselwa ukulinganisa ngokuchanekileyo ubunzima be-radial kunye noxinzelelo lokugoba.
Ukusika imilinganiselo yokumelana nokuxhatshazwa: Imigca yamandla exhunywe ngasemva kwemilinganiselo yokuxhatshazwa ibekwe kumacala omabini kwisakhelo soxinzelelo olusebenzayo kwi-45o orientation. Oku kusetyenziselwa ukulinganisa ngokuchanekileyo ubunzima bokusika. Iigeyiji zoxinzelelo lwe-resistance zisetyenziswa ngokubanzi kunye nenani elikhulu leegeyiji zokuxhathisa ukuphucula ukuchaneka.
Igeyiji enye yokumelana ne-amplifier yamandla edijithali ibizwa ngokuba yibhulorho yekota, iigeyiji ezimbini zokumelana ne-amplifier yamandla edijithali zibizwa ngokuba yibhulorho enesiqingatha, kwaye iigeyiji ezine zedijithali zokuxhathisa iamplifier zibizwa ngokuba yibhulorho epheleleyo. I-Resistance strain gage resistor transitions ayifani nokubeka ubunzima bebhetri egcwalisekayo kumandla axhasayo. Umgama woxinzelelo wenza ukuba igeyiji yokumelana nentsimbi ithambile kwaye ibe nde, iphakamisa isixhasi.
Amandla okuqinisa anciphisa ubukhulu bomlinganiselo wokumelana kunye nokunciphisa ukuchasana. I-gauge ye-resistance gauge ifakwe kumqolo omncinci (i-bracket esisigxina), efakwe ngokukhawuleza kwimodyuli yokulinganisa, ivumela ukuba i-resistance gauge ye-resistance gauge ivakale i-strain force ye-multihead weigher. Inguqu ye-resistor elinganiswe ngokuchanekileyo ngegage enye yokuxhathisa incinci kakhulu, malunga ne-0.12°.
Uvakalelo lwemodyuli yomthwalo luyanda ngenani leegeji zoxinzelelo ezikhutshiweyo. Indlela elungileyo yokuguqula olu tshintsho luncinci lube yinto enokwenzeka ngakumbi kukudibanisa njengeebhulorho zokukala ubunzima. Iindidi zeegeyiji zokuxhathisa ukuxhathisa zibekwe kwiindlela ezahlukeneyo, kwaye inyaniso ixhomekeke kuhlobo lwamandla olulinganiswe ngokuchanekileyo.
Ukugoba ukugoba, ukucheba, ukunyanzeliswa kweradial, itorque kunye noxinzelelo lokusebenza zonke zilinganiswa ngokuchanekileyo kusetyenziswa ulungiselelo olukhethekileyo lwengqiqo yokulinganisa ukuxhathisa. I-Smart weigh bridge circuit circuit ixhotyiswe nge-resistors ezine zokulinganisa kwaye isebenzisa i-voltage yokusebenza e-excitation eyaziwayo, njengoko kuboniswe ngezantsi: i-5 yi-voltage yokusebenza ezinzileyo eyaziwayo kunye ne-VO ilinganiswa ngokuchanekileyo. Ukuba zonke izixhasi zilinganisiwe, oko kuthetha ukuba i-R1/R2R3/R4 kwaye ke i-VO nguziro.
Ukuba kukho utshintsho kwelinye lemilinganiselo yokuchasana, kuya kubakho utshintsho olubangelwayo kwi-VO, enokulinganiswa ngokuchanekileyo kwaye ibonakaliswe ngokusebenzisa umthetho we-Ohm. UMthetho ka-Ohm ugxininisa ukuba inani langoku (I, kwi-amperes) elidlula kwi-conductor yombane phakathi kwamanqaku amabini lihambelana ngokufanelekileyo nombane osebenzayo (V) phakathi kwamanqaku amabini. I-Resistor (R, ilinganiswe ngokuchanekileyo kwi-ohms) ifakwe njengenkcazo eguquguqukayo kulo mbutho kwaye ayinanto yakwenza nokuhamba kwangoku.
Umthetho we-Ohm uchazwe kwifomula I=V/R. Xa isetyenziswe kwiiphetshana ezi-4 zephepha le-Smart weigh bridge power circuit, i-equation equation yilezi: Kwi-multihead weigher, oku kuxhathisa kuthathelwa indawo yi-resistance gauge ye-resistance gauge ekutshintshweni kwamandla okuxhasa kunye nomlinganiselo ochanekileyo wokunciphisa. Xa amandla ekhutshelwa kwibhetri enobunzima obutshajwayo, abaxhathisi kwigeyiji yokumelana noxinzelelo ngalunye kwaye iVO ilinganiswa ngokuchanekileyo.
Ukusuka kwiziphumo zolwazi lwedatha, i-VO inokucaciswa ngokulula kusetyenziswa inkqubo engentla ye-equations.
