Mhinduro dzeMatambudziko ekuyera maflowmeter eUltrasonic muMamiriro eMultiphase Flow​

Mukushandiswa kwemaindasitiri, ma ultrasonic flowmeters anowanzo sangana nemamiriro ezvinhu akaomarara apo medium iri mupaipi iri musanganiswa wezvikamu zvakawanda, senge musanganiswa wegasi nemvura, kana ine slurry uye tsvina. Kuyerera uku kwezvikamu zvakawanda kunogona kukanganisa zvakanyanya masaini e ultrasonic, zvichikonzera kuyerwa kusina kurongeka uye kusina kururama. Izvi zvinotevera zvinopa mhinduro dzinoshanda dzekugadzirisa matambudziko aya.​

Kugadzirisa Parameter yeMultiphase Flow​

1. Kusefa Zvirongwa​

• Kusefa Kunochinjika: Shandisa maalgorithms ekusefa anochinjika muchikamu chekugadzirisa masaini eflowmeter. Maalgorithms aya anogona kugadzirisa otomatiki maparameter efirita zvichienderana nehunhu hwemasaini eultrasonic anouya. Semuenzaniso, kana ruzha rwekamwe kamwe kana kupindira kukaitika nekuda kwemabubble egasi kana slurry particles, adaptive filter inogona kukurumidza kuchinjika kuti ideredze masaini aya asina kujairika, nokudaro ichivandudza chiyero chesaini - kune - ruzha.​

• Kusefa Avhareji Yekufambisa: Sefa inofamba inogona kushandiswa kururamisa huwandu hwemafambiro akayerwa. Nekuverenga avhareji yenhevedzano yenhamba dzedata dzakatevedzana pamusoro penguva yakatarwa, kuchinja kwenguva pfupi kunokonzerwa nekuyerera kwezvikamu zvakawanda kunogona kuderedzwa. Semuenzaniso, kana flowmeter ikaongorora data masekondi 0.1 ega ega, avhareji yekufamba kwesekondi imwe chete (kureva, avhareji yenhamba dzedata gumi dzakatevedzana) inogona kushandiswa kupa kubuda kwakasimba. Zvisinei, zvakakosha kuziva kuti hwindo refu kwazvo rinogona kuunza kunonoka mukupindura kuchinja kwemafambiro chaiwo, saka chiyero chinofanira kurohwa zvichienderana nezvinodiwa zvekushandisa.​

2. Kugadziriswa kweChiratidzo

• Gadza amplitude yakakodzera yechiratidzo uye frequency thresholds. Munzvimbo yekuyerera kwezvikamu zvakawanda, masaini e ultrasonic anogamuchirwa ne flowmeter anogona kusiyana neakajairika single - phase flow signals maererano ne amplitude uye frequency. Nekunyatsoongorora hunhu hwechiratidzo hwakajairika mukuvapo kwe multiphase flow muhurongwa hwepipeline chaiyo, flowmeter inogona kugadzirwa kuti isateerere masaini anowira kunze kwe defined threshold range. Izvi zvinobatsira kubvisa masaini enhema anokonzerwa nemagasi bubbles, tsvina, kana turbulent flow patterns asina hukama nekuyerera kwehuwandu hwemvura huru.​

MaModheru eFlowmeter Anokurudzirwa eMultiphase Flow​

1. MaDoppler Ultrasonic Flowmeters​

• MaDoppler ultrasonic flowmeters akakodzera zvikuru kushandiswa kwe multiphase flow kune ma solid particles kana gas bubbles mumvura. Ma flowmeters aya anoshanda zvichibva paDoppler effect, iyo inoitika kana ultrasonic wave inoratidzwa kubva mu moving particles kana mabubbles mumvura. Frequency shift ye reflection wave inoenderana nekumhanya kwezvinhu zvinofamba. Semuenzaniso, mu refinant treatment plant umo tsvina ine suspended solids uye mamwe magasi akanyungudutswa, Doppler ultrasonic flowmeter inogona kuyera flow rate nemazvo nekuona kufamba kwezvikamu izvi zvisina homogeneous mumvura.​

• Dzakagadzirirwa kubata mvura dzine mwero wakati wekusawirirana uye dzinogona kupa zviyero zvinovimbika zvekuyerera kunyangwe paine huwandu hwakawanda hwezvimedu kana mabubbles. Mamwe maDoppler ultrasonic flowmeters epamusoro anouyawo nemaalgorithms ekugadzirisa masaini akagadzirwa zvakananga kuti akwanise kuyerera kwezvikamu zvakawanda, zvichiwedzera kurongeka kwekuyera kwawo.​

2. Mafambiro eUltrasonic ane migero yakawanda​

• Ma flowmeter e ultrasonic anoshandisa ma ultrasonic transducers akawanda akaiswa panzvimbo dzakasiyana-siyana dzakatenderedza chikamu chepombi. Kurongeka uku kunobvumira kuyerwa kwakazara kwe flow profile mukati mepombi. Muzviitiko zvekuyerera kwe multiphase, kugoverwa kwe flow kunogona kunge kusina kufanana, ne gasi bubbles kana zvinhu zvinorema zve slurry zvakaungana munzvimbo dzakati dzepombi.​

• Nekuyera kumhanya kwekuyerera kwemvura panzvimbo dzakasiyana-siyana mupombi, muchina we ultrasonic flowmeter unogona kuverenga zviri nani kusafanana uku uye kuverenga avhareji yekuyerera kwemvura yakanyatsojeka. Semuenzaniso, mupaipi yemafuta negesi uko musanganiswa wemvura negesi unogona kupatsanurana kuita zvikamu zvakasiyana, muchina we flowmeter wemikana yakawanda unogona kuyera hunhu hwekuyerera kwechikamu chimwe nechimwe chakasiyana wobva wabatanidza data kuti uwane chiyero chakarurama chekuyerera kwemvura.​

Mhedziso​

Paunenge uchibata nekuyerera kwezvikamu zvakawanda mukushandiswa kwe ultrasonic flowmeter, kugadzirisa ma parameter akadai sekusefa kwakakodzera uye kugadzirisa mutsetse wechiratidzo kunogona kuvandudza zvakanyanya kurongeka kwekuyera. Pamusoro pezvo, kusarudza modhi yakakodzera ye flowmeter, senge Doppler kana multichannel ultrasonic flowmeters, yakagadzirirwa mamiriro chaiwo ekuyerera kwezvikamu zvakawanda kunogona kuve nechokwadi chekuti kuyerwa kwekuyerera kwakavimbika uye kwakasimba. Kana uchida rumwe rubatsiro mukushandisa mhinduro idzi kana uine mimwe mibvunzo ine chekuita nazvo, ndapota inzwa wakasununguka kubata timu yedu yerutsigiro rwehunyanzvi.
