Coriolis Misa Flow Meter Zinthu Zoyambira Zomwe Zimakhudza Magwiridwe Antchito & Mayankho

1. Kuyika Kupanikizika
Pakuyika kwa mita yothamanga, ngati sensor flange ya mita yotaya sikugwirizana ndi olamulira apakati a payipi (ndiko kuti, sensor flange siyikufanana ndi payipi ya payipi) kapena kusintha kwa kutentha kwa mapaipi, kupsinjika. opangidwa ndi payipi amayambitsa kuthamanga, torque ndi mphamvu yokoka pachubu choyezera cha mita yothamanga; zomwe zimayambitsa asymmetry kapena kupindika kwa kafukufuku wodziwikiratu, zomwe zimatsogolera ku zero kusuntha ndi kulakwitsa muyeso.
Yankho:
(1) Tsatirani mosamalitsa zomwe zikufotokozedwera mukayika mita yoyendera.
(2) Miyendo yothamanga ikayikidwa, imbani "zero zosintha menyu" ndikulemba mtengo wokonzeratu zero. Kusintha kwa ziro kukamalizidwa, onani mtengo wa ziro panthawiyi. Ngati kusiyana pakati pa zikhalidwe ziwirizi ndi zazikulu (ziwirizi ziyenera kukhala mu Order of magnitude), zikutanthauza kuti kupanikizika kwa kukhazikitsa ndi kwakukulu ndipo kuyenera kubwezeretsedwanso.
2. Environmental Vibration ndi Electromagnetic Interference
Pamene mita yothamanga ikugwira ntchito bwino, chubu choyezera chimakhala chogwedezeka ndipo chimakhala chokhudzidwa kwambiri ndi kugwedezeka kwakunja. Ngati pali magwero ena ogwedezeka papulatifomu yofananira kapena madera oyandikana nawo, kugwedezeka kwa magwero a kugwedezeka kumakhudzana ndi kugwedezeka kwachubu choyezera mita, zomwe zimapangitsa kugwedezeka kwachilendo ndi zero kugwedezeka kwa mita yoyenda, kuchititsa zolakwika muyeso. Zimapangitsa kuti mita yothamanga isagwire ntchito; panthawi imodzimodziyo, chifukwa sensa imagwedeza chubu choyezera kupyolera mu koyilo yosangalatsa, ngati pali kusokoneza kwakukulu kwa maginito pafupi ndi mita yothamanga, kudzakhalanso ndi zotsatira zazikulu pa zotsatira zoyezera.
Yankho: Ndi kuwongolera kosalekeza kwa ukadaulo wopanga mita ndi ukadaulo, mwachitsanzo, kugwiritsa ntchito ukadaulo waukadaulo wa DSP digito ndi ukadaulo wa MVD wa Micro Motion, poyerekeza ndi zida zam'mbuyomu za analogi, kutsogoloku Kukonzekera kwa digito kumachepetsa kwambiri phokoso lazizindikiro. ndikukulitsa chizindikiro choyezera. Miyendo yothamanga yokhala ndi ntchito zapamwambazi iyenera kuganiziridwa ngati yocheperako posankha chida. Komabe, izi sizimathetsa kusokonezako. Chifukwa chake, mita yothamanga ya misa iyenera kupangidwa ndikuyika kutali ndi zosintha zazikulu, ma mota ndi zida zina zomwe zimapanga maginito akuluakulu kuti asasokoneze maginito awo.
Pamene kusokonezeka kwa kugwedezeka sikungapewedwe, njira zodzipatula monga kulumikiza chitoliro chosinthika ndi chubu cha vibration ndi chimango chothandizira kudzipatula chimatengedwa kuti chilekanitse mita yothamanga kuchokera kugwero losokoneza kugwedezeka.
3. Mphamvu Yoyezera Kupanikizika Kwapakatikati
Pamene kuthamanga kwa ntchito kumasiyana kwambiri ndi kukakamiza kotsimikizira, kusintha kwa mphamvu yapakati yoyezera kungakhudze kulimba kwa chubu choyezera ndi kuchuluka kwa buden effect, kuwononga symmetry ya chubu choyezera, ndikupangitsa kuti sensa iwonongeke komanso kutengeka kwa kachulukidwe. kusintha, zomwe sizingakhoze kunyalanyazidwa kuti muyese molondola.
Yankho: Titha kuthetsa kapena kuchepetsa izi pochita kubwezera kukakamiza ndi kusinthasintha zero pa mita yothamanga kwambiri. Pali njira ziwiri zokhazikitsira chipukuta misozi:
(1) Ngati kuthamanga kwa ntchito kuli mtengo wokhazikika wodziwika, mutha kuyikapo mtengo wakunja kwamagetsi pamagetsi othamanga kuti mubweze.
(2) Ngati mphamvu yogwiritsira ntchito ikusintha kwambiri, makina oyendetsa mita amatha kukonzedwa kuti asankhe chipangizo choyezera kuthamanga kwa kunja, ndipo mphamvu yeniyeni ya nthawi yeniyeni ingapezeke kudzera mu chipangizo choyezera kuthamanga kwa kunja kuti chilipidwe. Zindikirani: Mukakonza chipukuta misozi, chiwongolero chotsimikizira kuthamanga chiyenera kuperekedwa.
4. Vuto lakuyenda kwa magawo awiri
Chifukwa teknoloji yamakono yopanga mita yothamanga imatha kuyeza molondola gawo limodzi lokha, muyeso yeniyeni yoyezera, pamene mikhalidwe yogwirira ntchito ikusintha, sing'anga yamadzimadzi idzasungunuka ndikupanga kutuluka kwa magawo awiri, zomwe zimakhudza muyeso wamba.
Yankho: Sinthani magwiridwe antchito a sing'anga yamadzimadzi, kuti thovu munjira yamadzimadzi amagawidwa mofanana momwe angathere kuti akwaniritse zofunikira za mita yoyenda kuti muyezedwe bwino. Mayankho ake enieni ndi awa:
(1) Kuyala chitoliro chowongoka. Vortex yoyambitsidwa ndi chigongono mu payipi imapangitsa kuti thovu la mpweya lilowe mu chubu la sensa mosafanana, zomwe zimapangitsa kuti pakhale zolakwika.
(2) Wonjezerani kuthamanga kwa magazi. Cholinga cha kuonjezera kuchuluka kwa otaya ndi kupanga thovu mu magawo awiri otaya kudutsa mu chubu kuyeza pa liwiro lofanana ndi pamene amalowa mu chubu kuyeza, kuti athetse buoyancy wa thovu ndi zotsatira za otsika- kukhuthala kwamadzimadzi (mathovu amadzimadzi ocheperako sikophweka kumwazikana ndipo amakonda kusonkhana m'magulu akulu); Mukamagwiritsa ntchito ma micro Motion flow metre, tikulimbikitsidwa kuti kuthamanga kwapakati sikuchepera 1/5 pamlingo wonse.
(3) Sankhani kuyika paipi yoyima, yolowera m'mwamba. Pakuthamanga kochepa, thovu lidzasonkhana mu theka lapamwamba la chubu choyezera; kukhathamira kwa thovu ndi sing'anga yoyenda imatha kutulutsa thovuzo mosavuta pambuyo poyika chitoliro choyima.
(4) Gwiritsani ntchito chowongolera kuti chithandizire kugawa thovu mumadzimadzi, ndipo zotsatira zake zimakhala bwino zikagwiritsidwa ntchito ndi getter.
5. Mphamvu Yoyezera Kachulukidwe Wapakatikati ndi Viscosity
Kusintha kwa kachulukidwe ka sing'anga yoyezera kudzakhudza mwachindunji kayendedwe ka kayendedwe ka kayendedwe kake, kotero kuti kusinthasintha kwa sensa yothamanga kudzasintha, kuchititsa zero kuchepetsa; ndi mamasukidwe akayendedwe a sing'anga adzasintha makhalidwe damping dongosolo, kutsogolera ziro kuchepetsa.
Yankho: Yesani kugwiritsa ntchito sing'anga imodzi kapena zingapo popanda kusiyana pang'ono mu kachulukidwe.
6. Kuyeza kwa Tube Corrosion
Pogwiritsira ntchito mita yothamanga kwambiri, chifukwa cha zotsatira za dzimbiri zamadzimadzi, kupsinjika kwakunja, kulowa kwa zinthu zakunja ndi zina zotero, zomwe zimayambitsa kuwonongeka kwa chubu choyezera, zomwe zimakhudza momwe chubu choyezera chimagwirira ntchito ndikuyambitsa kuyeza kolakwika.
Yankho: Ndibwino kuti muyike fyuluta yofananira kutsogolo kwa mita yothamanga kuti zinthu zakunja zisalowe; kuchepetsa kupanikizika kwa unsembe pa unsembe.
