- Kev tu thiab kev saib xyuas tsis zooKev sib sau ua ke ntawm cov xim seem ua rau lub probe rhiab heev thiab ua rau cov txiaj ntsig tsis raug, tshwj xeeb tshaj yog nyob rau hauv cov kab ke uas muaj xim ntau heev. Kev ua raws li kev ntxuav thiab kev saib xyuas tom qab ua ntau pawg daws qhov teeb meem no.
- Kev xaiv cov cuab yeej tsis raugKev xaiv lub viscometer uas tsis haum rau cov xim rheology - piv txwv li, siv lub cuab yeej tig yooj yim rau cov xim thixotropic - tuaj yeem ua rau muaj qhov yuam kev tas mus li.
- Kev teb qeeb rau qhov kev hloov pauvYog tias tsis siv cov lus ceeb toom tiag tiag thiab tsis teb cov lus teb, cov khoom tsis raws li qhov tau teev tseg yuav tsis pom. Cov khoom siv ntsuas viscosity hauv kab uas txuas nrog cov txheej txheem tswj hwm tuaj yeem txo qhov kev saib xyuas tes.
Yuav kom tsis txhob muaj tej yam teeb meem no:
- Ib txwm ua kom paub tseeb tias qhov kev teeb tsa tiav lawm nrog cov lus qhia ntawm tus neeg tsim khoom lossis kev tshuaj xyuas CFD.
- Siv cov txheej txheem uas them rau qhov kub thiab xyuas kom meej qhov kev kho kom raug tsis tu ncua.
- Ntxuav cov probes kom huv si.
- Txuas cov khoom siv xaiv rau cov txheej txheem ntsuas qhov viscosity ntawm cov xim tshwj xeeb uas cuam tshuam rau cov khoom siv.
- Kev sib xyaw ua ke cov tswb ceeb toom tiag tiag thiab cov txheej txheem kho cov txheej txheem tsis siv neeg.
Cov lus qhia txog kev txij nkawm thiab kev ntsuas qhov ntsuas rau cov inline viscosity probes
Kev saib xyuas thiab kev ntsuas kom zoo ua kom muaj qhov tseeb ntawm cov txheej txheem txiav txim siab qhov viscosity ntawm cov xim, ua kom lub probe siv tau ntev dua, thiab txhawb nqa kev ua haujlwm zoo.
- Kev Ntxuav Txhua HnubTshem tawm cov xim uas sib sau ua ke tom qab txhua zaus ua tiav, tshwj xeeb tshaj yog cov xim uas tau pleev xim ntau heev lossis cov xim uas khov sai. Siv cov tshuaj yaj thiab cov cuab yeej uas cov chaw tsim khoom pom zoo kom tiv thaiv kev puas tsuaj rau lub sensor.
- Kev Teem Caij Calibration: Kho cov probes raws li lub sijhawm teev tseg los ntawm cov qauv zoo, lossis tom qab kev kho kom zoo. Siv cov kua dej siv los yog cov xim pleev uas ua raws li cov txheej txheem.
- Kev Txheeb Xyuas Sensor: Txheeb xyuas cov kev ntsuas inline nrog cov cuab yeej kuaj viscosity xim offline siv cov qauv kev lag luam.
- Cov ntaub ntawv pov thawjKhaws cov ntaub ntawv ntawm kev saib xyuas, kev ntsuas, thiab kev lees paub cov haujlwm kom ntseeg tau tias taug qab tau thiab ua raws li txoj cai.
- Kev Teeb tsa thiab Qhov Chaw Zoo Tshaj PlawsSiv cov lus qhia—thiab, qhov twg muaj, cov kev nkag siab los ntawm kev tshawb fawb CFD—los xaiv qhov tob ntawm lub sensor, kev sib phim, thiab qhov ceev ntawm cov dej ntws.
- Kev Tshuaj Xyuas thiab Kev Kuaj Mob Pom Kev: Tshuaj xyuas cov sensors tsis tu ncua seb puas muaj kev puas tsuaj lossis cov khoom seem, thiab siv cov haujlwm kuaj mob hauv lub tsheb kom paub txog kev ua haujlwm tsis zoo thaum ntxov.
Cov kev saib xyuas tsis yog tsuas yog ua kom cov ntsuas viscosity ntawm cov xim ua haujlwm tau zoo tshaj plaws xwb tab sis kuj pab txhawb rau kev ntsuas cov xim ntws kom tswj tau qhov zoo thiab txo cov khib nyiab ntawm cov txheej txheem. Kev saib xyuas tsis tu ncua rau cov ntsiab lus no txo qhov tsis ua haujlwm thiab ua raws li kev hloov pauv ntawm kev ruaj khov thiab cov qauv ib puag ncig hauv kev tsim xim niaj hnub.
