Kodi Vortex Flow Meter ndi chiyani?
A vortex flow mitandi chipangizo anaika mu dongosolo otaya processing kuti azindikire vortices kwaiye monga madzimadzi akudutsa bluff thupi. Amagwiritsidwa ntchito kwambiri pokonza gasi, madzi ndi nthunzi poyezera kuyenda kuti apititse patsogolo kupanga bwino komanso kugawa.
Mfundo Yogwira Ntchito ya Vortex Flow Meter
Ma vortices amakhetsedwa motsatira mbali zonse za thupi la bluff pamene madzi akudutsa mu chinthu chosasinthika. Kusiyanasiyana kwapanikiza komwe kumachitika panthawiyi kumayenderana mwachindunji ndi liwiro lothamanga. Kuchuluka kwa vortex kukhetsedwa kumazindikiridwa kuti awerengere kuchuluka kwa kuthamanga. Ndiye mafupipafupi adzamasuliridwa kukhala chizindikiro chomwe chimapereka muyeso wolondola wa volumetric kapena misa yamadzimadzi, mpweya, ndi nthunzi.
Kapangidwe Kapangidwe ka Vortex Flow Meters
316 Chitsulo chosapanga dzimbiri kapena Hastelloy ndiye chinthu choyambirira chomwe chimapangidwa ndi mita yoyenda momwemo, kuphatikiza thupi la bluff, sensa yolumikizidwa ya vortex ndi zida zamagetsi zotumizira. Avortex kukhetsa madzi otaya mitalikupezeka mu makulidwe a flange kuchokera ku ½ mpaka 12 mu. Komanso, mtengo woyika avortex kukhetsa mitandi mpikisano kuposa wa orifice mamita kukula pansi pa mainchesi sikisi.
Makulidwe ndi mawonekedwe a thupi labluff ngati masikweya ndi amakona anayi adutsa muzoyeserera kuti akwaniritse zomwe mukufuna. Zotsatira zoyeserera zikuwonetsa kuti mzere ndi kukhudzika kwa mbiri ya liwiro ndizosiyana pang'ono ndi mawonekedwe a thupi la bluff. Thupi la bluff liyenera kukhala ndi gawo lalikulu lokwanira la m'mimba mwake. Kenako otaya onse nawo mu kukhetsa. Ngakhale kuchulukirako kumathamanga, m'mbali zotuluka m'mphepete mwa mtsinje ndi njira yapadera yofunikira kuti mugawire mizere yolekanitsa.
Pakadali pano, ma vortex metres ambiri amaphatikiza masensa amtundu wa piezoelectric kapena capacitance kuti ayeze kuthamanga kwa oscillation pafupi ndi thupi la bluff. Masensa awa amatulutsa siginecha yotsika yamagetsi ngati kuyankha kupsinjika kwamphamvu. Zizindikiro zotere zimakhala ndi ma frequency ofanana ndi oscillation. Masensa am'madzi ndi otsika mtengo amatha kusinthidwa mosavuta komanso osinthika pa kutentha kwakukulu kuchokera ku zakumwa za cryogenic kupita ku nthunzi yotentha kwambiri.
Chifukwa Chiyani Musankhe Vortex Flow Meters?
Palibe magawo osuntha omwe amatsimikizira kukhazikika, kukonza kochepa komanso kudalirika kwanthawi yayitali pamakina opangira. Ma flow metre oterowo amawonekeranso poyezera mitundu yosiyanasiyana yamadzimadzi molondola, ngakhale kutentha ndi kupanikizika kosiyanasiyana. Ndendende chifukwa cha kuchuluka kwa magwiridwe antchito komanso machitidwe abwino kwambiri mumiyezo yolondola komanso yobwerezabwereza, ndi njira zothetsera mafakitale omwe amawona kulondola. Kuchepetsa ndalama zogwirira ntchito komanso kukhazikitsa kosavuta ndi zifukwa zina ziwiri monga njira yothetsera.
Kulondola ndi Kusanja
Kusiyanasiyana kwa ma vortex flowmeters kumachepa pamene mamasukidwe akayendedwe akuchulukirachulukira pakutsika kwa nambala ya Reynolds ndi mamasukidwe amphamvu akukwera. Kuchuluka kwa viscosity ceilling kumakhala mkati mwa 8 ~ 30 centipoises. Ngati mita ya vortex ili ndi kukula koyenera kuti igwiritsidwe ntchito, munthu akhoza kuyembekezera kusiyana kwabwinoko kusiyana ndi 20: 1 ya gasi ndi nthunzi, ndi 10: 1 yamadzimadzi otsika kwambiri.
Kusalondola kwa ma vortex flow metres kumasiyana ndi manambala a Reynolds. Kusalondola kotere kwa ma vortex flowmeters ambiri kumakhala pakati pa 0.5% ndi 1% pomwe kumakwera mpaka 10% pomwe Reynolds amawerengera ochepa kuposa 10,000. Vortex mita imakhala ndi malo odulirapo omwe akuwonetsa pafupi ndi ziro. Zotsatira za mita zimatsitsidwa paziro pomwe Reynolds amawerengera kapena kuchepera 10,000. Palibe vuto ngati kuyenda kocheperako kudikirira kuyeza kumakhala kawiri pagawo lodulidwa. Mayendedwe otsika sakanayesedwa molondola poyambira, kutseka ndi zina zokhumudwitsa chifukwa cha kusanja kwawo.
Kuchulukitsa Kuchita Mwachangu ndi Kuchepetsa Mtengo
Othandizira amatha kusintha ndikuwongolera kuyenda kwa zakumwa, mipweya kapena kutumiza kwa nthunzi kudzera pamakina opangira kutengera kuyeza kolondola koyenda. Kuti kugawa bwino kukhale bwino pomwe kugwiritsa ntchito mphamvu kumatsitsidwa. Zonsezi, kuphatikiza ma mita oyendawa m'makina opangira makina ndizothandiza pakuwongolera magwiridwe antchito, kuchepetsa nthawi yopumira komanso kukulitsa zokolola zonse.
Zochepa za Vortex Flowmeter
Mamita a Vortex nthawi zambiri si abwino kwa ma batching kapena njira zoyenda pang'onopang'ono chifukwa cha kuchepa kwa magwiridwe antchito pamayendedwe otsika. Makamaka, kuchuluka kwa ma dribble ma batching station kumatha kutsika pansi pamlingo wocheperako wa Reynolds mita wa vortex, zomwe zimapangitsa kuti zikhale zolakwika. Pamene kukula kwa batchi kukucheperachepera, kuthekera kwa zolakwika za kuyeza kumawonjezeka, zomwe zimapangitsa mita kukhala yodalirika pakugwiritsa ntchito izi. Ndikofunikira kusankha mita yoyendera yomwe ingathe kuthana ndi mawonekedwe oyenda omwe amafunikira pakuchita zotere kuti mupewe zolakwika zazikulu.
Gulu lathu la akatswiri ndi okonzeka kupereka mayankho ogwirizana omwe amakwaniritsa zosowa zamakampani anu, kaya ndi mafuta ndi gasi, kukonza mankhwala, kapena machitidwe a HVAC. Ndi kudzipereka pakuchita bwino ndi magwiridwe antchito, timapereka chithandizo chokwanira kuti muwonetsetse kuti mumasankha vortex flow mita yoyenera kuti mugwiritse ntchito. Lumikizanani nafe lero kuti mukambirane makonda anu ndikuwona momwe ma flowmeter athu angasinthire kuwongolera kwanu komanso kuchita bwino.
