Rau qhov hnyav aseptic lub hnab tsis ruaj khov, cais qhov nruab nrab ntawm qhov sib txawv ntawm lub hnab ntim ntau dhau, tom qab ntawd tshawb xyuas cov khoom thiab lub valve ua haujlwm siv lub hauv paus ntsiab lus ntsuas. Txheeb xyuas qhov ntsuas qhov ntsuas thiab qhov hnyav lub hnab ntim ua ntej, thiab txiav txim los ntawm kev rov ua dua nyob rau hauv cov xwm txheej sib piv.
Lub hnab hnyav sib txawv txhais tau li cas?
Lub hnab hnyav sib txawv yog hais txog qhov sib txawv ntawm cov ntsiab lus tiag tiag thiab lub hom phiaj. Nug ob lo lus nug: Puas yog qhov nruab nrab sau rau ntawm lub hom phiaj, thiab qhov sib nrug deb npaum li cas yog lub hnab hnyav tshaj plaws thiab hnyav tshaj plaws? Ob leeg tuaj yeem ua yuam kev ib zaug. Qhov nruab nrab qhov tseeb ib leeg tsis txhais tau tias txhua lub hnab ntim tau txais.
Vim li cas ob qhov xwm txheej xav tau kev kuaj xyuas sib txawv?
Ib qho offset tsis tu ncua taw qhia koj rau kev teeb tsa thiab kev ntsuas tsis tu ncua. Kev nthuav dav dav hu rau kev saib ze dua ntawm kev hloov pauv thiab qhov ua haujlwm valve. Kaum lub hnab muab qhov screen thawj zaug; siv lub rooj kom nqaim qhov kev tshawb nrhiav thiab sau cov ntaub ntawv ntxiv qhov xav tau.

Cov khoom nws tus kheej txav qhov hnyav li cas?
Cov khoom tuab tuaj yeem khaws cia tom qab kaw lus txib. Huab cua tuaj yeem cuam tshuam cov ntsuas ntsuas, thiab qhov ntsuas kub tseem ceeb thaum ntsuas qhov ntim tau hloov mus rau qhov hnyav siv qhov ceev. Lub load cell ntsuas huab hwm coj ncaj qha, yog li nws tsis xav tau qhov hloov dua siab tshiab. Nws tseem xav tau lub platform ruaj khov thiab tswj tau nres rau qhov ntws.
Txoj kev ntsuas twg haum rau yam khoom twg?
Pib los ntawm kev nug seb tus muab tub lim paub tias lub hnab ntim puv. Load cells hnyav nws, electromagnetic meters ntsuas ntim, thiab Coriolis meters ntsuas qhov loj. Lawv cov tshev sib txawv. Ob lub hnab 200 litre thiab 1000 litre ntim tuaj yeem siv cov ntsuas ntws; loj ib leeg tsis txiav txim siab qhov system.

Vim li cas kos valve teb nrog rau cov sensors?
Cov lus txib kaw tsis nres cov khoom tam sim ntawd. Valve teb thiab dripping tom qab kaw tuaj yeem hloov qhov hnyav kawg, thaum lub sensor tuaj yeem ya tsis muaj lub tswb. Sib piv cov teeb liab thiab kaw lus txib nrog lub hnab ntim tiav lawm. Ntawm lub tshuab taub hau ntxaib, khaws cov ntaub ntawv sib cais rau txhua lub taub hau kom qhov nruab nrab tsis tuaj yeem nkaum qhov offset.
Thaum twg yog qhov chaw thiab thaum twg yog qhov teeb meem xaiv?
Tsis ncaj ncees lawm tare, lub hom phiaj lossis cov nyiaj them tuaj yeem raug kho hauv qhov chaw. Sensor drift, hnav lub valve, kev sib cuag nrog lub platform hnyav lossis cov khoom tsis ruaj khov xav tau lawv tus kheej kho. Kev ua tsis tiav calibration tsis ua pov thawj tias lub tshuab raug xaiv tsis raug. Tshawb xyuas nws cov kev txwv kev ua haujlwm ua ntej txiav txim siab txog cov cuab yeej tshiab.
Yuav ua li cas yuav tsum tau kuaj xyuas ntawm qhov txais?
Pom zoo rau cov khoom, lub hnab, ceev thiab siv nplai ua ntej txais. Ntsuas peb caug lub hnab sib law liag, kaw qhov nruab nrab qhov hnyav qhov yuam kev thiab qhov sib txawv ntawm qhov sib sib zog nqus thiab hnyav tshaj plaws. Piv txwv li, ± 0.5% ntawm 200 kg lub hom phiaj txhais tau tias ± 1 kg. Siv qhov kam rau ua tau pom zoo rau qhov project; qhov piv txwv tsis yog kev thov kom raug.
Lub takeaway yog cais cov qauv, xyuas qhov ntsuas qhov cuam tshuam, tom qab ntawd txheeb xyuas qhov kho. Ob qhov nruab nrab qhov hnyav thiab lub hnab hloov pauv yuav tsum tau ua kom tau raws li qhov kev pom zoo.
