Cov ntsiab lus yooj yim thiab kev siv cov txuj ci kev ua haujlwm ntawm ntau lub taub hau weigher

Tus Sau: Smartweigh– Multihead Weighter

Multihead weigher yog lub ntsuas qib kua rub, uas yog ntau dua hauv cov ntaub ntawv hom ntawv ntsuas qhov tseeb thiab kev ntsuas qhov tseeb dynamic. 1. Lub ntsiab lus ntawm multihead weigher coj mus rau hauv tus account qhov puas tsuaj ntawm lub ntiajteb txawj nqus acceleration (g) thiab vapor buoyancy (f) siv qhov chaw nyob ntxaws ntxaws, thiab yog raws li kev hloov pauv ib qho ntawm qhov ntsuas raug (pawg) mus rau lwm qhov Kev ntsuas meej (tso zis) Lub zog sensor rau kev ntsuas qhov tseeb. 2. Cov ntsiab lus tseem ceeb ntawm multihead weigher Polyurethane khoom Polyurethane elastomer (kev co isolator, ntau dua rhiab heev beam) ua rau elastic deformation nyob rau hauv qhov kev ua ntawm lub zog sab nraud, yog li ntawd lub zog tiv thaiv gauge (hloov pauv hluav taws xob ntaus ntawv) pasted rau ntawm nws qhov chaw kuj ua rau deformation, tsis kam Tom qab lub zog tiv thaiv gauge yog deformed, nws tus nqi tsis kam yuav ua rau muaj kev hloov pauv (nthuav dav lossis txo qis), thiab tom qab ntawd qhov kev hloov pauv tsis kam no yuav raug hloov pauv mus rau hauv cov ntaub ntawv teeb liab ntawm lub cuab yeej hluav taws xob los ntawm lub voj voog ntsuas qhov tseeb, yog li ua tiav kev hloov pauv ntawm lub zog sab nraud mus rau hauv cov ntaub ntawv teeb liab ntawm lub cuab yeej hluav taws xob. tag nrho cov txheej txheem.

Nws tuaj yeem pom tias lub ntsuas kev ntxhov siab tiv taus, cov khoom siv polyurethane polyurethane elastomer thiab lub voj voog ntes yog ntau qhov tseem ceeb uas tsis tuaj yeem tsis muaj nyob rau hauv qhov kev txiav txim siab tiv taus hom multihead weigher. Peb yam no tau tham luv luv hauv qab no. 1. Lub ntsuas kev ntxhov siab tiv taus Lub ntsuas kev ntxhov siab tiv taus yog ib daim ntawm lub ntsuas kev ntxhov siab tiv taus uas nthuav cov xov hlau cua sov rau ntawm phab ntsa lossis cov khoom siv ua los ntawm cov khoom siv organic.

Ib qho ntawm nws cov yam ntxwv tseem ceeb yog tus nqi ntawm kev ceeb toom K. Thaum nws ob sab raug rau lub zog F, nws yuav khoov thiab ntev, uas yog ua rau deformation. Yog tias xav tias nws khoov thiab ntev, nws thaj chaw hla ntu raug txo qis, uas yog, nws lub voj voog hla ntu raug txo qis.

Tus coefficient ntawm resistivity elasticity (kev hloov pauv ntawm kev tiv thaiv) ntawm qhov ntsuas kev tiv thaiv thiab lub zog tensile (kev hloov pauv ntawm qhov ntev) ntawm cov hlau cua sov muaj feem cuam tshuam zoo rau tus nqi nyob. Nws yuav tsum tau sau tseg tias qhov kev qhia tshwj xeeb ntawm tus nqi ntsuas kev rhiab heev K tus nqi yog ib qho parameter uas tswj hwm thiab txiav txim siab los ntawm cov yam ntxwv ntawm cov khoom siv raw rau kev ua cov hlau sib xyaw ua ke cua sov hlau. Nws tsis muaj dab tsi ua rau qhov tsos, kev qhia tshwj xeeb, qauv thiab kev qhia tshwj xeeb ntawm qhov ntsuas kev tiv thaiv. Tus nqi feem ntau yog 1.7—3.6 Nruab Nrab; qhov thib ob, tus nqi K yog qhov ntau thiab tsawg tsis muaj qhov ntev, uas yog, nws tsis muaj qhov ntev. Hauv lub hauv paus kho tshuab, ΔL/L hu ua kev txiav txim siab, qhia ua ε, thiab nws yog siv los qhia tias plasticity feem ntau zoo li loj heev, uas tsis yooj yim heev, thiab ib lab ntawm nws feem ntau siv ua lub tuam txhab, qhia ua με.

2. Cov khoom siv polyurethane Polyurethane elastomer Cov khoom siv polyurethane Polyurethane elastomer yog ib qho khoom uas muaj qhov tsos tshwj xeeb. Nws muaj ob txoj haujlwm. Thaum pib, nws yog lub luag haujlwm rau lub zog sab nraud uas lub tshuab ntsuas ntau lub taub hau raug kev txom nyem, thiab lub zog sab nraud ua rau lub zog teb kom ntseeg tau tias muaj kev sib npaug; Lub ntsuas kev tawm tsam muaj kev xav ntau dua los ua tiav txoj haujlwm txhua hnub ntawm kev hloov pauv ntawm cov ntaub ntawv teeb liab ntawm lub cuab yeej hluav taws xob. 3. Kev Tshawb Fawb Circuit Court Lub luag haujlwm ntawm kev tshawb fawb Circuit Court yog hloov qhov kev hloov pauv ntawm qhov kev tawm tsam ntawm lub ntsuas kev tawm tsam mus rau hauv qhov tso zis hluav taws xob ua haujlwm.

Vim tias tus choj Wheatstone muaj ntau yam zoo, xws li nws tuaj yeem tiv thaiv kev puas tsuaj ntawm qhov kub thiab txias, tuaj yeem tiv thaiv kev puas tsuaj ntawm sab, thiab tuaj yeem daws qhov teeb meem ntawm lub tshuab ntsuas ntau lub taub hau yooj yim dua thiab sai dua, yog li tus choj Wheatstone tau txais hauv lub tshuab ntsuas ntau lub taub hau. Ntau yam kev siv. Vim yog qhov rhiab heev ntawm lub voj voog ntawm cov saw hlau puv ntoob thiab lwm cov choj caj npab, cov yam ntxwv yooj yim ntawm txhua caj npab yog tib yam, thiab ntau yam kev phom sij tuaj yeem yooj yim them rov qab rau ib leeg. Circuit Court.
