Wolemba: Smartweigh-Multihead Weighter
Multihead weigher ndi makina omwe amasintha mphamvu ya kinetic kuchokera kunjira ina kupita kwina. Mwachindunji, multihead weigher ndi mphamvu yamagetsi yomwe imasintha mphamvu zamakina (monga mphamvu yothandizira, kuchepa, kuthamanga kwa ntchito kapena torque) kukhala zizindikiro zamagetsi zomwe zingathe kuyesedwa molondola. Mphamvu yopondereza ya chizindikiro cha data imasintha ndi mphamvu yopondereza ya mphamvu yotulutsa.
Pali mitundu itatu yoyambira ya multihead weigher kutengera chizindikiro cha data: hydraulic, pneumatic ndi resistance strain gauge. Mtundu wodziwika kwambiri wa weigher womwe umagwiritsidwa ntchito popanga mafakitale ndi woyezera mutu wambiri wokhala ndi zovuta zomangidwa. Chojambulira chojambulira cha multihead weigher chimakhala ndi thupi lolimba lachitsulo (kapena "elastic yellow component") lomwe limakonza kukana kukana.
Nyumbayo nthawi zambiri imapangidwa ndi aluminiyamu, chitsulo cha kaboni kapena mbale yachitsulo chosapanga dzimbiri, zomwe zimapangitsa kuti ikhale yolimba kwambiri koma yodumphira kwambiri. Makhalidwe a multihead weigher amawonongeka pang'ono pamene sikelo ikugwiritsidwa ntchito, koma imabwereranso ku mawonekedwe ake oyambirira, pokhapokha ngati ili katundu. Pofuna kuyankha bwino pakusintha kwa mawonekedwe a thupi, kukana kupsinjika kwamphamvu kumasinthanso mawonekedwe ake.
Izi zimabweretsa kusintha kwa kukana kwa gage yolimbana nayo, yomwe imatha kuyeza bwino ngati kusintha kwamagetsi. Chifukwa kusintha kotereku kumayenderana ndi kulemera kwa ukonde komwe kumatulutsidwa, kulemera kwa chinthucho kumatha kutsimikiziridwa kuchokera pakusintha kwamagetsi. Kodi choyezera mitu yambiri chimagwira ntchito bwanji? Kuti muyankhe "Kodi choyezera mitu yambiri chimagwira ntchito bwanji?" muyenera kumvetsetsa kaye kuti "Kodi geji yoyezera mphamvu imagwira ntchito bwanji?" A resistance strain gauge ndi chipangizo chomwe chimayesa molondola kusintha kwa resistor pamene mphamvu yatulutsidwa.
Chingwe chodziwikiratu chimakhala ndi mawaya abwino kwambiri a zojambulazo, zomwe zimayikidwa mu gridi, zomwe zimapangitsa kuti chopinga cha waya chisinthike pamene mphamvu yamagetsi imatulutsidwa motsatira mbali imodzi. Pali mitundu yosiyanasiyana ya ma gage olimbana nawo oti musankhe: Linear resistance gauge: Chingwe chamagetsi cholumikizidwa kumbuyo kwa choyezera chopinga ndi chofanana ndi m'mphepete mwa sikelo ya kukana. Izi zimagwiritsidwa ntchito poyezera molondola kuchuluka kwa ma radial ndi kupindika kwa mafunde.
Kudula zoyezera kukaniza: Mizere yamagetsi yolumikizidwa kumbuyo kwa zoyezera zovuta zimayikidwa kumbali zonse ziwiri za chimango chogwira ntchito pamayendedwe a 45o. Izi zimagwiritsidwa ntchito poyesa molondola kuchuluka kwa kudula. Zoyezera zovuta za Resistance nthawi zambiri zimagwiritsidwa ntchito limodzi ndi kuchuluka kwa zoyezera zopinga kuti zitheke kulondola.
Digital power amplifier resistance strain gauge imatchedwa quarter bridge, ma digital power amplifier resistance gauge amatchedwa half Bridge, ndipo ma digital power amplifier resistance gauge amatchedwa mlatho wathunthu. Kusintha kwa resistance gage resistor sikufanana ndi kulemetsa batire yowonjezedwanso mu mphamvu yothandizira. Kutalikirana kwamphamvu kumapangitsa kuti strain gauge ikhale yofewa komanso yayitali, kukweza chopinga.
Mphamvu yomangirira imafupikitsa makulidwe a jekeseni wotsutsa ndikuchepetsa kukana. Kukaniza kutsekemera kumamangiriridwa kumbuyo kopyapyala (chokhazikika chokhazikika), chomwe chimamangiriridwa nthawi yomweyo ku gawo lolemera, kulola kuti mphamvu yotsutsa imve mphamvu ya multihead weigher. Kusintha kwa resistor komwe kumayesedwa molondola ndi gage imodzi yotsutsa ndikochepa kwambiri, pafupifupi 0.12°.
Kukhudzika kwa module yolemetsa kumawonjezeka ndi kuchuluka kwa ma gauges otulutsa. Njira yabwino yosinthira kusintha kwakung'onoku kukhala chinthu chotheka ndikuwalumikiza ngati milatho yolemetsa ya Smart. Mitundu ya zoyezera zovuta za kukana Zoyezera zamtundu wa kukana zimayikidwa mosiyanasiyana, ndipo chowonadi chili mu mtundu wa mphamvu yomwe imayesedwa molondola.
Kutopa, kumeta ubweya, kupsinjika kwa ma radial, torque ndi mphamvu yogwirira ntchito zonse zimayesedwa molondola pogwiritsa ntchito njira yapadera yodziwira kukana. Dongosolo la Smart Weigh Bridge lili ndi zoletsa zinayi zofananira ndipo limagwiritsa ntchito mphamvu yamagetsi yodziwikiratu yodziwika bwino, monga tawonera pansipa: 5 ndiye magetsi okhazikika okhazikika ndipo VO imayesedwa molondola. Ngati zopinga zonse zili bwino, zikutanthauza kuti R1/R2R3/R4 ndiyeno VO ndi ziro.
Ngati pali kusintha kwa chimodzi mwazotsutsa, padzakhala kusintha kwa VO, komwe kungayesedwe molondola ndikuwonetseratu pogwiritsa ntchito lamulo la Ohm. Lamulo la Ohm likugogomezera kuti kuchuluka kwa masiku ano (I, mu amperes) kudutsa pa conductor magetsi pakati pa mfundo ziwiri kumagwirizana bwino ndi magetsi ogwiritsira ntchito (V) pakati pa mfundo ziwirizi. Resistor (R, yoyesedwa molondola mu ohms) imayambitsidwa ngati tanthawuzo losinthika mu chiyanjano ichi ndipo sichikugwirizana ndi kuyenda kwamakono.
Lamulo la Ohm likufotokozedwa mu ndondomeko I = V / R. Mukagwiritsidwa ntchito pamizere 4 yamapepala a Smart weigh bridge power circuit, zotsatira zake ndi izi: Mu weigher ya multihead, kukana uku kumasinthidwa ndi kukana strain gauge m'malo mwa mphamvu yothandizira ndi kuyeza kolondola kwa shrinkage. Mphamvu ikatulutsidwa ku batire yoyezedwanso yoyezeranso, zopinga pakusintha kwamtundu uliwonse wotsutsa ndipo VO imayesedwa molondola.
Kuchokera pazomwe zachitika, VO imatha kufotokozedwa mosavuta pogwiritsa ntchito dongosolo la equation lomwe lili pamwambapa.
