Mokhoa oa ho netefatsa ho nepahala ha li-vortex flowmeters libakeng tse nang le mocheso o phahameng?

Ho netefatsa ho nepahala ha li-vortex flowmeters libakeng tse nang le mocheso o phahameng, ho hlokahala motsoako oa ntlafatso ea khetho ea mohlala, tšireletso ea ho kenya, maano a ho lekanya le tlhokomelo ea ts'ebetso. Ka tlase ke tataiso e hlophisitsoeng, e ka sebelisoang e etselitsoeng maemo a mocheso o phahameng:

1. Khetha Mefuta le Lisebelisoa tse ntlafalitsoeng ke Mocheso o Phahameng

• Khetha li-flowmeter tse khethehileng tsa vortex tsa mocheso o phahameng: Khetha mehlala e lekantsoeng ka ho hlaka bakeng sa mocheso oo u o reretseng (mohlala, 400–550℃ bakeng sa lits'ebetso tse feteletseng tsa indasteri). Mefuta ena e na le meaho ea sensor e matlafalitsoeng le likarolo tsa elektroniki tse hanelang mocheso o phahameng ho qoba ho sisinyeha ha lets'oao ho bakoang ke katoloso ea mocheso.
• Netefatsa hore thepa e lumellana:
  • Sesebediswa sa ho lemoha se lokela ho etswa ka di-alloy tsa mocheso o phahameng (mohlala, Inconel 625) kapa thepa ya letsopa ho hanela ho bola le ho fetoha ha mocheso.
  • Likarolo tsa ho kwala (mohlala, di-gasket) di lokela ho sebedisa thepa e sa futhumatseng jwalo ka di-graphite kapa di-gasket tsa tshepe ho ena le rabara e tlwaelehileng, e ka senyehang mochesong o phahameng mme ya baka ho dutla kapa diphoso tsa tekanyo.
  • Thepa ea karolo ea phaephe e lokela ho lumellana le mokhoa o mahareng le mocheso ho thibela ho se lumellane ha katoloso ea mocheso ho sitisang tšimo ea phallo ea mokelikeli.

2. Ntlafatsa ho Kenya ho Fokotsa Tšitiso ea Thermal

• Arola transmitter ho mocheso o phahameng: Li-transmitter tse ngata tsa vortex flowmeter ha lia etsetsoa ho pepesehela mocheso o phahameng ka ho toba. Kenya transmitter hole (mohlala, limithara tse 1-2 hole le sensor) u sebelisa likhoele tsa katoloso, kapa u kenye lithebe tsa mocheso/sekoahelo pakeng tsa sensor le transmitter. Bakeng sa mehlala e kopantsoeng, khetha tse nang le li-transmitter tse qhalang mocheso.
• Netefatsa maemo a phallo e tsitsitseng: Fokotsa tšitiso ea ho thothomela: Litikoloho tse nang le mocheso o phahameng hangata li kenyelletsa lipompo kapa li-compressor tse hlahisang ho thothomela. Kenya li-bracket tse thibang ho thothomela pakeng tsa flowmeter le phaephe, 'me u sebelise lihokelo tse tenyetsehang ho arola ho thothomela ha mechini, ho ka etsisang matšoao a vortex le ho baka lipalo tse fosahetseng.
  • Boloka likarolo tse hlokahalang tsa phaephe e otlolohileng (hodimo ho ≥ 10×DN, tlase ho ≥ 5×DN; eketsa ho ya hodimo ho ≥ 20×DN haeba di-valve/di-elbow di le haufi) ho qoba ditshitiso tsa phallo tse bakwang ke ho arolwa ha mocheso diphaepheng tsa mocheso o phahameng.
  • Kenya flowmeter ka tsela e otlolohileng bakeng sa khase/mouoane ho thibela lipokotho tsa moea kapa ho bokellana ha condensate, e leng se ka sitisang tlhahiso ea vortex. Bakeng sa metsi, etsa bonnete ba hore phallo e felletseng ea phaephe e qoba liphoso tsa phaephe e se nang letho.

3. Lekanya Maemo a Tshebetso a Mocheso o Phahameng

• Lekanya tlas'a mocheso oa sebele oa ho sebetsa: Litekanyetso tse tloaelehileng tsa laboratori (hangata mochesong oa kamore) li kanna tsa se bonts'e ts'ebetso mochesong o phahameng. Etsa tlhahlobo ea kahare kapa u romele flowmeter laboratoring ea tlhahlobo e ka etsisang mocheso oa hau oa ts'ebetso le maemo a khatello. Sena se ikarabella bakeng sa litlamorao tsa mocheso ho sensor le thepa ea mokelikeli (mohlala, viscosity, liphetoho tsa bongata mouoaneng).
• Sebelisa mehlala e lefelloang mocheso: Bakeng sa lits'ebetso tsa mouoane kapa khase, khetha li-vortex flowmeter tse nang le li-sensor tsa mocheso le khatello tse hahiloeng kahare (mehlala e feto-fetohang). Mehlala ena e lefella ka bo eona liphetoho tsa bongata ba mokelikeli le lebelo tse bakoang ke ho feto-fetoha ha mocheso, ho netefatsa lipalo tse nepahetseng tsa phallo ea boima/bophahamo ntle le liphetoho tsa letsoho.
• Theha kemiso ea tlhahlobo ea nako le nako: Lithempereichara tse phahameng li ka potlakisa ho senyeha ha likarolo. Lekanya flowmeter likhoeli tse ling le tse ling tse 6-12 (kapa ho latela maemo a indasteri joalo ka JJG 1030-2007) ho netefatsa ho nepahala le ho lokisa ho hoholeha hofe kapa hofe.

4. Kenya tšebetsong Tlhokomelo le Tlhokomelo ea Ts'ebetso

• Lekola mocheso le tshebetso ya nako ya sebele: Kopanya flowmeter le sistimi ya hao ya DCS/PLC ho latela data ya mocheso le phallo. Beha ditemoso bakeng sa ho phahama ho sa tlwaelehang ha mocheso kapa ho kheloha ha sekgahla sa phallo, tse ka bontshang ho senyeha ha sensor kapa mathata a ho kenya.
• Etsa tlhokomelo khafetsa: Qoba ho tšoha ha mocheso: Ha o qala kapa o tima sistimi, fetola mocheso butle-butle ho thibela katoloso/ho honyela ha mocheso ka potlako, e leng se ka senyang karolo ea sensor kapa ea phaephe.
  • Hlahloba likarolo tsa ho koala bakeng sa matšoao a ho senyeha ha mocheso (mohlala, ho petsoha, ho thatafala) 'me u li nkele sebaka ka mokhoa o sebetsang.
  • Hloekisa probe ea sensor nako le nako ho tlosa sekala kapa li-depositi life kapa life tse ka thibelang ho bonoa ha vortex—sebelisa lisebelisoa tsa ho hloekisa tse lumellanang le mocheso o phahameng ho qoba ho senya probe.
  • Hlahloba dithapo tsa katoloso le dikgokelo bakeng sa tshenyo e bakwang ke mocheso (mohlala, ho petsoha ha insulation) mme o di nkele sebaka haeba ho hlokahala.

5. Sebetsana le Mehopolo e Ikhethang ea Mokelikeli

• Bakeng sa ts'ebeliso ea mouoane: Netefatsa hore mouoane o tletse ka botlalo kapa o futhumetse haholo (ha ho marotholi a metsi) ho qoba phallo ea mekhahlelo e 'meli, e sitisang ho thehoa ha vortex. Sebelisa sefi sa mouoane holimo haeba ho hlokahala ho tlosa condensate.
• Bakeng sa maro a mocheso o phahameng: Netefatsa hore palo ea Reynolds ea sesebelisoa e lula e le kaholimo ho 2000 (bonyane bakeng sa tlhahiso e tsitsitseng ea vortex) mochesong o sebetsang. Lithempereichara tse phahameng li ka fokotsa ho hlaka ha metsi, e leng se ka thusang ho boloka palo e loketseng ea Reynolds—bala sena u sebelisa data ea 'nete ea ho hlaka e itšetlehileng ka mocheso.
