Munyori: Smartweigh–Multihead Weighter
Iyo yakakosha musimboti uye hunyanzvi hwekushandisa hwemultihead weigher Iyo yakawanda inoyera ndeyekunetsekana uye kudzvanywa sensor, iyo inowanzoshandiswa mukuyera kwakaringana kweiyo static data uye inoshanduka kuyerwa kwakaringana. 1. Tsanangudzo ye multihead weigher inonyatso funga nezve kukurumidza kwemagetsi (g) yekero yekushandisa uye buoyancy (f) yemvura yegesi, maererano nekushandurwa kweimwe yeakanyatso kuyerwa (hutano) mune imwe yakanyatsoyerwa (yakabuda) . ) kunyatsoyera kunaka kwesimba sensor. 2. Pfungwa yekutanga ye multihead weigher Polyurethane elastomer (vibration isolator, danda rinonyanya kujeka) rinokonzeresa deformation pasi pesimba rekunze, kuitira kuti gauge yekurwisa (shanduko yechikamu) inonamirwa pamusoro wayo inokonzerawo deformation, uye dhizaini yekudzivirira gauge deform. kuti, kukosha kwayo kupikisa kuchachinja (kuwedzera kana kuderera), uye ipapo resistor ichashandurwa kuita chiratidzo chemagetsi kuburikidza nechiyero chakaringana chemagetsi emagetsi, uyezve maitiro ese ekushandura simba rekunze kuita chiratidzo chemagetsi. kupera.
Hazvina kuoma kuona kuti resistance strain gauges, polyurethane elastomers uye test power circuits akawanda akakosha zvikamu izvo zvisingagone kushaikwa mune resistor strain force multihead weigher. Aya matanho matatu anotsanangurwa muchidimbu pazasi. 1. Resistance strain gauge The resistance strain gauge chidimbu chemagetsi ekupisa waya mechanical equipment yakapararira pamusoro pe substrate yakagadzirwa nehupenyu hwehupenyu, kureva, chiyero chekudzivirira.
Chimwe chezvipimo zvake zvakakosha ndeye dexterity index K. Kana mativi ake maviri akaiswa pasi pesimba reF, inogona kutambanudza, nemamwe mazwi kukonzera deformation. Tichifunga kuti yakatambanudzwa, nzvimbo yayo yemuchinjikwa inova diki, kureva kuti, chikamu chayo chepakati-chitenderedzwa semicircle chinoderera.
Ukama huri pakati pekupikisa elastic coefficient yekudzivirira strain gauge (kuchinja kwehukama kwechigadziro) uye kureba kwetambo yekupisa (kushanduka kwehurefu uye kupfupika) kwakaenzana. Izvo zvinofanirwa kutaurwa kuti saizi yekunzwa indekisi K kukosha ndeye parameter inotarwa nehunhu hweiyo mbishi yekugadzira simbi yekupisa waya. Izvo hazvina chekuita nechitarisiko uye saizi yekupikisa strain gauge. Iko kukosha kweK yezvakasiyana mbishi zvinhu zvinowanzo mu 1.7—3.6 Pakati; iyo inotevera K kukosha ihuwandu husina dimensionless, kureva kuti, haina chiyero. Muchiinjiniya mechanics, ΔL / L inonzi strain force, inoratidzwa se ε, uye inowanzoshandiswa kuratidza kuti ductility yakakura kwazvo, iyo inonyanya kukanganisa. Inowanzo shandiswa semirioni imwe yebhizinesi, inoratidzwa se με.
2. Polyurethane elastomer Polyurethane elastomer chikamu chine chimiro chakasiyana. Ine mabasa maviri. Kutanga, inotakura simba rekunze remuyerero wemultihead, izvo zvinokonzeresa kuti recoil simba riwane chiyero chakaringana; Iyo yekupikisa strain gauge yakanamirwa nenzvimbo iyi yakanakira basa rezuva nezuva rekushandura simba rekumanikidza uye chiratidzo chemagetsi. 3. Kuongororwa kwemagetsi ekugadzirisa magetsi Basa rekuongororwa kwemagetsi ekugadzirisa magetsi nderokushandura resitori yekupikisa gauge mukushanda kwemagetsi.
Nekuti bhiriji reWheatstone rine zvakanakira zvakawanda, sekukwanisa kudzvanya kukuvadza kwekushanduka kwetembiricha, kudzvanya simba repadivi, uye kukwanisa kubata nyore nyore dambudziko remuripo weiyo multihead weigher, bhiriji reWheatstone rakashandiswa zvakanyanya iyo multihead weigher. use. Sezvo ruoko bhiriji redunhu senge yakazara kuunganidza cheni ndiyo inonyanya kunzwisiswa, iwo makuru maparamita eruwoko rumwe norumwe akafanana, uye njodzi dzeakasiyana pesvedzero dziri nyore kwazvo kumisa mumwe nemumwe, saka iyo yakawanda weigher inoshandisa iyo yakazara kuunganidza ketani uye. mamwe mazambuko emaoko.
