Momwe mungawerengere mita ya flow?

Kuwongolera mita yoyendaNdikofunikira pakuwonetsetsa kuyeza kolondola m'mafakitale kapena musanachitike. Ziribe kanthu zamadzimadzi kapena mpweya, ma calibration ndi chitsimikizo china chowerengera zolondola, zomwe zimatengera muyezo wovomerezeka. Imachepetsanso kuopsa kwa zolakwika ndikuwonjezera magwiridwe antchito okhudzana ndi mafakitale monga mafuta ndi gasi, kukonza madzi, petrochemical, etc.

Kodi ma flowmeter calibration ndi chiyani?

Flow meter calibration imatanthauza kusintha mawerengedwe omwe adayikidwa kale kuti athe kugwera m'mphepete mwa zolakwika. Ndizotheka kuti mita imasunthika pakapita nthawi chifukwa cha magwiridwe antchito osiyanasiyana, zomwe zimapangitsa kuti miyeso ichepe kwambiri. Mafakitale monga opanga mankhwala kapena kukonza mphamvu amaika patsogolo kulondola kuposa magawo ena, chifukwa ngakhale kusiyana pang'ono kumatha kubweretsa kusakwanira, kuwononga zida zopangira kapena zovuta zachitetezo.

Kulinganiza kochitidwa ndi opanga kapena pogwiritsa ntchito makina odziyimira pawokha kumatengera miyezo yamakampani, monga miyezo yoperekedwa ndi National Institute of Standards and Technology (NIST) ku US kapena Van Swinden Laboratory ku Europe.

Kusiyana Pakati pa Calibration ndi Recalibration

Kuwongolera kumatanthauza kusintha koyamba kwa mita yothamanga pomwe kukonzanso kumaphatikizapo kukonzanso mita itagwiritsidwa ntchito pakanthawi. Kulondola kwa mita yothamanga kumatha kutsika chifukwa chakuvala kwachilendo komanso kung'ambika komwe kumayambitsidwa ndi ntchito yanthawi ndi nthawi. Kukonzanso nthawi zonse ndikofunikira mofanana ndi kuyesa koyambirira munjira zosiyanasiyana komanso zovuta zamafakitale.

Recalibration imaganiziranso mbiri ya ntchito komanso zotsatira za chilengedwe. Masitepe onsewa amatchinjiriza kukonzanso kwakukulu komanso kovutirapo komanso kupanga kuzovuta, zolakwika ndi zopatuka.

Njira za Flow Meter Calibration

Njira zingapo zoyendetsera ma flow meters zakhazikitsidwa bwino, molingana ndi mitundu yamadzimadzi ndi mita. Njira zotere zimatsimikizira kugwira ntchito kwa ma flow metres potsatira miyezo yomwe idafotokozedweratu.

Kufananiza Pakati pa Mamita Awiri Oyenda

Miyendo yoyenda yomwe imayenera kuyesedwa imayikidwa mndandanda ndi yolondola motsatira mfundo zina. Kuwerengera kuchokera pamamita onse awiriwa kumayerekezedwa poyesa kuchuluka kwamadzi komwe kumadziwika. Kusintha kofunikira kudzapangidwa molingana ndi mita yolondola yodziwika bwino ngati pangakhale zopatuka pamphepete mwawo. Njira iyi ingagwiritsidwe ntchito kuwerengeraelectromagnetic flow mita.

Gravimetric Calibration

Kuchuluka kwamadzimadzi pa nthawi yoikika kumayesedwa, kenako kumabwera kuyerekeza pakati pa kuwerenga ndi zotsatira zowerengedwa. Aliquot yamadzimadzi imayikidwa mu mita yoyesera kenaka kuyeza madzimadzi pa nthawi yodziwika ngati masekondi makumi asanu ndi limodzi. Werengani kuchuluka kwa mayendedwe pongogawa voliyumu ndi nthawi. Onetsetsani ngati kusiyana pakati pa zotsatira zowerengeka ndi kuwerenga kugwera m'malire ololedwa. Ngati sichoncho, sinthani mita ndikusiya kuwerenga pamalo ovomerezeka. Njirayi imagwiritsidwa ntchito kuwerengeramisa flow mita.

Piston Prover Calibration

Piston prover calibration ndi yoyenera ma calibrations ampweya wothamanga mamita, kugwiritsa ntchito pisitoni yokhala ndi voliyumu yodziwika mkati kuti ikakamize kuchuluka kwamadzimadzi kudzera mu mita yothamanga. Yezerani kuchuluka kwa madzimadzi kupita kutsogolo kwa pisitoni. Kenako yerekezerani kuwerenga kowonetsedwa ndi voliyumu yodziwika ndikusintha moyenera ngati kuli kofunikira.

Kufunika kwa Kukonzanso Kwanthawi Zonse

Kulondola kwa mita yothamanga kumatha kutsika pakapita nthawi munjira zazikulu komanso zovuta kukonza monga mankhwala, zakuthambo, mphamvu ndi chithandizo chamadzi. Kuwonongeka kwa phindu ndi kuwonongeka kwa zida kungabwere chifukwa cha kuyeza koyenda molakwika, komwe kumabweretsa zotsatira zachindunji pamitengo ndi phindu.

Mamita oyenda omwe amagwiritsidwa ntchito kuti azindikire kutayikira kwa makina sangapereke kuwerengera kokwanira kuti azindikire kutayikira kapena kuwonongeka kwa zida, monga zomwe zimapezeka m'makampani amafuta ndi gasi kapena makina amadzi am'tauni.

Zovuta Zomwe Mumakumana Nazo Mukayesa Flow Meter

Kuwongolera ma mita othamanga kumatha kubwera ndi zovuta, monga kusiyanasiyana kwamadzimadzi, kutentha, ndi kusintha kwa chilengedwe. Kuphatikiza apo, zolakwika zamunthu pakuwongolera pamanja zitha kuyambitsa zolakwika. Zida zamagetsi ndi mapulogalamu apamwamba zimagwiritsidwa ntchito kwambiri kuti ziwongolere kulondola, kupereka ndemanga zenizeni zenizeni komanso zosintha potengera deta yogwira ntchito.
