Momwe Mungasankhire Choyezera Kuyenda kwa Channel Choyenera: Buku Lotsogolera Lonse

1. Mvetsetsani Zofunikira Zanu Zofunsira Ntchito

 

• Mtundu ndi Makhalidwe a Madzi: Taganizirani mtundu wa madzi omwe akuyesedwa. Kodi ndi madzi oyera, madzi otayidwa okhala ndi zinthu zolimba, kapena madzi owononga kwambiri? Mwachitsanzo, m'malo oyeretsera madzi otayidwa, madziwo akhoza kukhala ndi zinthu zolimba zotayidwa, mafuta, ndi zinthu zina zodetsa. Pazochitika zotere, choyezera madzi chomwe chingathe kuthana ndi zinthuzi popanda kutsekeka kapena kuwonongeka ndikofunikira. Doppler ultrasonic flow meter nthawi zambiri ndi chisankho chabwino poyezera madzi okhala ndi zinthu zolimba, chifukwa amagwiritsa ntchito Doppler effect kuti azindikire kuyenda kwa tinthu tating'onoting'ono m'madzi.
• Chiŵerengero cha Kuthamanga kwa Madzi: Dziwani kuchuluka kwa madzi komwe kumafunikira kuyeza. Mamita osiyanasiyana otseguka a njira zoyezera madzi ali ndi mphamvu zosiyanasiyana zoyezera kuchuluka kwa madzi. Mamita ena amapangidwira kugwiritsa ntchito madzi otsika, pomwe ena amatha kuthana ndi kuthamanga kwa madzi. Mwachitsanzo, m'njira zazing'ono zothirira,kuyendakuchuluka kwa madzi kungakhale kochepa, pomwe m'ngalande zazikulu zamadzi amvula, kuchuluka kwa madzi kumatha kukhala kwakukulu kwambiri pakagwa mvula yambiri. Ndikofunikira kusankha mita yomwe ingayeze molondola mkati mwa kuchuluka kwa madzi komwe mukuyembekezeredwa kugwiritsa ntchito.
• Kukula ndi Mawonekedwe a Channel: Kukula ndi mawonekedwe a Channel yotseguka zimathandizanso kwambiri pakusankha mita. Channel yotseguka imatha kusiyana kuyambira yopapatiza komanso yosaya mpaka yayikulu komanso yakuya. Flow mita imapezeka m'makulidwe osiyanasiyana komanso mawonekedwe kuti igwirizane ndi miyeso yosiyanasiyana ya Channel. Pa Channel zozungulira, mitundu ina ya ma wairs kapena flumes ingakhale yoyenera, pomwe pa Channel zozungulira kapena trapezoidal, njira zina zoyezera zingakhale zoyenera. Kuphatikiza apo, kutsetsereka kwa Channel kumatha kukhudza mawonekedwe a flow mita ndipo, motero, kusankha flow mita.

2. Unikani Ukadaulo Woyezera

 

• Ma Weirs ndi Flumes: Izi ndi zida zachikhalidwe zomwe zimagwiritsidwa ntchito poyezakuyendam'njira zotseguka. Mawero ndi nyumba zomwe zimayikidwa kudutsa njira zomwe zimakakamiza madzi kuti ayende pamwamba pa chivundikiro kapena pamwamba. Poyesa kuchuluka kwa madzi pamwamba pa weir, kuchuluka kwa madzi kumatha kuwerengedwa pogwiritsa ntchito njira zokhazikitsidwa. Mawero, kumbali ina, ndi magawo opapatiza a njira zomwe zimapanga ubale wodziwika pakati pa kuchuluka kwa madzi ndi kuchuluka kwa madzi. Mawero ndi ma flume ndi osavuta komanso odalirika, koma amafunika kuyikidwa mosamala ndi kuyesedwa. Amakhudzidwanso ndi zinthu monga kusungunuka kwa madzi ndi kusonkhanitsa zinyalala.
• Ma Ultrasonic Flow Meters: Ma Ultrasonic open channel flow meter amagwiritsa ntchito ma ultrasound waves poyesa liwiro la madzi kapena kuchuluka kwa madzi mu channel. Transit - nthawi yomwe ma ultrasound flow meter amayesa nthawi yomwe ma ultrasound waves amayendera kumtunda ndi kumunsi kwa mtsinje, pomwe Doppler ultrasonic flow meter imazindikira kusintha kwa ma frequency a ma ultrasound waves omwe amawonetsedwa ndi tinthu ta madzi mu fluid. Ma Ultrasonic flow meter amapereka muyeso wosalowerera, wolondola kwambiri, komanso kuthekera koyesa kuchuluka kwa madzi. Sakhudzidwanso kwambiri ndi matope ndi zinyalala poyerekeza ndi zida zamakina. Komabe, amatha kukhudzidwa ndi thovu la mpweya kapena thovu pamwamba pa madzi.
• Ma Electromagnetic Flow Meters: Ngakhale kuti nthawi zambiri amagwiritsidwa ntchito poika mapaipi otsekedwa, ma electromagnetic flow meter amathanso kusinthidwa kuti agwiritsidwe ntchito motseguka. Amagwira ntchito motsatira lamulo la Faraday la induction ya electromagnetic, kupanga mphamvu ya maginito kudutsa mayendedwe ndikuyesa mphamvu ya electromotive yomwe imachokera. Ma electromagnetic flow meter amapereka miyeso yolondola komanso yodalirika, sakhudzidwa ndi kukhuthala kapena kusinthasintha kwa madzi, ndipo amatha kuyeza kuchuluka kwa mayendedwe osiyanasiyana. Komabe, amafunikira madzi oyendetsera ndi nthaka yoyenera kuti agwire ntchito molondola.

3. Ganizirani Zolondola ndi Kulinganiza

 

• Kulinganiza: Kulinganiza nthawi zonse n'kofunika kuti zitsimikizire kuti mita yoyezera kuyenda ikupitirizabe kulondola. Mamita ena oyezera kuyenda ndi osavuta kuwalinganiza kuposa ena. Mwachitsanzo, mamita oyezera kuyenda a ultrasonic nthawi zambiri amakhala ndi zinthu zoyezera kuyenda, pomwe makoma ndi ma flume angafunike njira zovuta zoyezera kuyenda. Ganizirani zofunikira pakulinganiza ndi kupezeka kwa ntchito zoyezera kuyenda posankha mita yoyezera kuyenda.

4. Kukhazikitsa ndi Kusamalira

 

• Kukhazikitsa: Ma flow meters ena, monga ma ultrasound flow meters, amatha kukhazikitsidwa mosavuta popanda ntchito yaikulu yomanga. Akhoza kuyikidwa m'mbali mwa ngalande kapena pa mlatho pamwamba pa ngalande. Mosiyana ndi zimenezi, kukhazikitsa ma weirs ndi ma flumes kungafunike ntchito yayikulu yaukadaulo, kuphatikizapo kufukula ndi kumanga nyumbayo. Ganizirani zofunikira pakukhazikitsa, nthawi ndi ndalama zomwe zingagwiritsidwe ntchito, komanso kusokoneza komwe kungachitike pakuyenda kwa madzi panthawi yokhazikitsa.
• Kusamalira: Kusamalira nthawi zonse kumafunika kuti choyezera madzi chigwire bwino ntchito. Mitundu yosiyanasiyana ya zoyezera madzi ili ndi zofunikira zosiyanasiyana pakusamalira. Mwachitsanzo, makoma ndi ma flume amafunika kutsukidwa nthawi zonse kuti achotse zinyalala ndi zinyalala, pomwe zoyezera madzi zamagetsi zingafunike kutsukidwa nthawi ndi nthawi kwa ma transducer. Ganizirani kuchuluka kwa kukonza, zovuta za ntchito zosamalira, komanso kupezeka kwa zida zina posankha.

5. Kulankhulana ndi Kutulutsa Deta

 

• Ma Protocol Olumikizirana: Yang'anani zoyezera kuyenda kwa data zomwe zimathandiza ma protocol olumikizirana ofanana, monga Modbus, HART, kapena Ethernet. Ma protocol awa amalola kuti flow meter iphatikizidwe ndi ma data acquisition system, SCADA (Supervisory Control and Data Acquisition) systems, kapena zida zina zowunikira ndi kulamulira. Izi zimathandiza kuyang'anira kutali, kulemba deta, ndi kusanthula deta ya kuyenda kwa data nthawi yeniyeni.
• Kutulutsa Deta: Choyezera kuyenda kwa madzi chiyenera kupereka zotsatira zothandiza za deta, monga kuchuluka kwa madzi, kuyenda kwa madzi, ndi kuchuluka kwa madzi. Ma flow meters ena angaperekenso zinthu zina, monga kuthekera kosungira deta komanso kuthekera kopanga malipoti. Ganizirani zofunikira pakutulutsa deta pa pulogalamu yanu ndikusankha choyezera kuyenda kwa madzi chomwe chingakwaniritse zosowazo.

6. Zoganizira za Mtengo

 

• Mtengo Woyamba Kugula: Mitundu yosiyanasiyana ya zoyezera madzi ndi mitundu ya zoyezera madzi zimakhala ndi mitengo yosiyana. Kawirikawiri, zoyezera madzi ndi zoyezera madzi zomwe zimagwiritsidwa ntchito ndi ma ultrasound zingakhale zodula kuposa ma weirs ndi flumes, koma zimapereka magwiridwe antchito abwino komanso ndalama zochepa zosamalira pakapita nthawi.
• Mtengo Wonse wa Umwini: Ganizirani mtengo wonse wa umwini pa nthawi yonse ya mita yoyendera. Chida choyezera madzi chokwera mtengo kwambiri chomwe chili ndi ndalama zochepa zokonzera komanso kulondola kwakukulu chingakhale ndalama zabwino kwambiri kwa nthawi yayitali poyerekeza ndi mita yotsika mtengo yomwe ili ndi zofunikira zambiri zokonzera komanso kulondola kochepa.
