Multihead weighter yog rub cov kua qib sensor, uas muaj ntau dua hauv cov ntaub ntawv hom kev ntsuas qhov tseeb thiab ntsuas qhov tseeb. 1. Lub ntsiab lus ntawm multihead weigher yuav siv sij hawm rau hauv tus account qhov kev puas tsuaj ntawm lub ntiajteb txawj nqus acceleration (g) thiab vapor buoyancy (f) siv cov ncauj lus kom ntxaws chaw nyob, thiab yog raws li converting ib qho ntawm qhov raug ntsuas (mas) mus rau lwm qhov kev ntsuas qhov tseeb (tso zis. ) Lub zog sensor rau kev ntsuas qhov tseeb. 2. Cov ntsiab lus tseem ceeb ntawm ntau lub taub hau hnyav Polyurethane cov khoom siv Polyurethane elastomer (kev co isolator, ntau rhiab nqaj) ua rau elastic deformation nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, thiaj li hais tias cov kuj strain gauge (conversion electronic device) pasted rau nws nto kuj ua rau deformation. , kev tiv thaiv Tom qab lub ntsuas ntsuas tau deformed, nws cov nqi tiv thaiv yuav ua rau muaj kev hloov pauv (kev nthuav dav lossis txo qis), thiab tom qab ntawd qhov kev hloov pauv no yuav raug hloov mus rau hauv cov ntaub ntawv teeb liab ntawm ib qho khoom siv hluav taws xob los ntawm kev ntsuas qhov tseeb, yog li ua tiav qhov kev hloov pauv ntawm sab nraud quab yuam mus rau hauv cov ntaub ntawv teeb liab ntawm lub tshuab hluav taws xob. tag nrho cov txheej txheem.
Nws tuaj yeem pom tau tias qhov ntsuas qhov ntsuas tsis zoo, cov khoom siv polyurethane polyurethane elastomer thiab kuaj xyuas Circuit Court yog ob peb yam tseem ceeb uas tsis tuaj yeem tsis muaj qhov kev txiav txim siab hom multihead hnyav. Peb yam no tau tham luv luv hauv qab no. 1. Resistance strain gauge The resistance strain gauge yog ib qho ntawm cov kev ntsuas kev tiv thaiv kab mob uas kis tau cov khoom siv hluav taws xob cua sov rau ntawm phab ntsa lossis cov khoom ua los ntawm cov khoom siv organic.
Ib qho ntawm nws qhov tseem ceeb tsis tseem ceeb yog qhov kev ceeb toom qhov ntsuas tus nqi K. Thaum nws ob tog raug F quab yuam, nws yuav ua rau flexion thiab txuas ntxiv, uas yog hais tias ua rau deformation. Piv txwv tias nws flexion thiab ncua ntxiv, nws qhov chaw hla ntu yog txo, uas yog, nws lub vojvoog cross-sectional vojvoog yog txo.
Lub resistivity elasticity coefficient (tus txheeb ze hloov ntawm qhov tsis kam) ntawm qhov ntsuas qhov ntsuas tsis kam thiab lub zog tensile (kwv yees hloov ntawm qhov ntev) ntawm cov cua sov xaim yog qhov muaj feem cuam tshuam nrog tus nqi nyob. Nws yuav tsum tau muab sau tseg tias qhov specification ntawm qhov rhiab heev Performance index tus nqi K tus nqi yog ib tug parameter uas yog tswj thiab txiav txim siab los ntawm cov yam ntxwv ntawm cov khoom siv raw rau kev ua cov hlau composite cua sov hlau. Nws tsis muaj dab tsi ua nrog rau cov tsos, specification, qauv thiab specification ntawm cov kuj strain gauge. Tus nqi feem ntau yog 1.7—3.6 Nruab nrab; Qhov thib ob, tus nqi K yog qhov tsis muaj qhov ntau, uas yog, nws tsis muaj qhov loj me. Nyob rau hauv lub hauv paus tshuab, ΔL / L yog hu ua kev txiav txim, denoted li ε, thiab nws yog siv los piav qhia tias plasticity feem ntau zoo li loj heev, uas yog heev tsis yooj yim, thiab ib lab ntawm nws yog feem ntau siv raws li ib tug tuam txhab, denoted li. µ ua.
2. Polyurethane khoom Polyurethane elastomer Polyurethane khoom Polyurethane elastomer yog ib qho kev tivthaiv uas muaj qhov txawv txav. Nws muaj ob txoj haujlwm. Thaum pib, nws yog lub luag hauj lwm rau sab nraud quab yuam raug kev txom nyem los ntawm lub multihead weighter, thiab sab nraud quab yuam ua rau muaj kev cuam tshuam quab yuam los xyuas kom meej qhov sib npaug; Qhov ntsuas qhov ntsuas qhov ntsuas yog qhov muaj txiaj ntsig ntau dua los ua haujlwm txhua hnub ntawm kev hloov pauv ntawm cov ntaub ntawv teeb liab ntawm cov khoom siv hluav taws xob. 3. Kev kuaj xyuas Circuit Court Kev ua haujlwm ntawm kev kuaj xyuas Circuit Court yog los hloov qhov kev hloov pauv ntawm qhov ntsuas qhov ntsuas qhov tsis kam mus rau hauv cov qauv ntsuas hluav taws xob ua haujlwm.
Vim tias tus choj Wheatstone muaj ntau yam zoo, xws li nws tuaj yeem cuam tshuam qhov kev puas tsuaj ntawm qhov kub thiab txias, tuaj yeem cuam tshuam rau sab quab yuam kev puas tsuaj, thiab tuaj yeem daws cov teeb meem ntawm cov khoom siv ntau lub taub hau kom yooj yim dua thiab sai, yog li Wheatstone choj tau txais hauv multihead hnyav. Kev siv dav dav. Vim lub siab rhiab heev ntawm Circuit Court ntawm tag nrho-stacking saw thiab lwm yam caj npab txuas hniav, cov yam ntxwv ntawm txhua caj npab yog tib yam, thiab ntau yam kev phom sij tuaj yeem yooj yim offset ib leeg. Circuit Court.
