Izisombululo zeMingeni yoKulinganisa i-Ultrasonic Flowmeter kwiimeko zokuHamba kweMigangatho emininzi

Kwizicelo zoshishino, ii-ultrasonic flowmeters zihlala zidibana neemeko ezinzima apho i-medium kwipayipi ingumxube wezigaba ezininzi, njengomxube wegesi kunye nolwelo, okanye equlethe i-slurry kunye nokungcola. Olu hambo lwezigaba ezininzi lunokuphazamisa kakhulu imiqondiso ye-ultrasonic, nto leyo ekhokelela kumaxabiso okulinganisa angaqinisekanga nangalunganga. Oku kulandelayo kubonelela ngezisombululo ezisebenzayo zokujongana nale mingeni.​

Ukulungiswa kweParameter ye-Multiphase Flow​

1. Useto lokucoca​

• Ukucoca Okuziqhelanisayo: Sebenzisa ii-algorithms zokucoca eziziqhelanisayo kwiyunithi yokucubungula isignali ye-flowmeter. Ezi algorithms zinokulungisa ngokuzenzekelayo iiparameters zokucoca ngokusekelwe kwiimpawu zemiqondiso ye-ultrasonic engenayo. Umzekelo, xa ingxolo ekhawulezileyo okanye ukuphazamiseka kuvela ngenxa yamaqamza egesi okanye amaqhekeza e-slurry, isihluzo esiziqhelanisayo sinokuziqhelanisa ngokukhawuleza ukuze sinciphise ezi signals zingaqhelekanga, ngaloo ndlela siphucula umlinganiselo wengxolo yesignali ukuya kwingxolo.​

• Ukucoca Okuphakathi Kokuhamba: Isihluzi esiphakathi esihambayo singasetyenziselwa ukuthambisa amaxabiso okuhamba alinganisiweyo. Ngokubala umyinge woluhlu lwamanqaku edatha yokulinganisa alandelelanayo kwixesha elithile, ukutshintshatshintsha kwexesha elifutshane okubangelwa kukuhamba kwezigaba ezininzi kunokuncitshiswa. Umzekelo, ukuba i-flowmeter isampulu yedatha rhoqo emva kwemizuzwana eyi-0.1, umyinge ohambayo wesekhondi enye (oko kukuthi, umyinge wamanqaku edatha ali-10 alandelelanayo) ungasetyenziswa ukubonelela ngemveliso ezinzileyo ngakumbi. Nangona kunjalo, kubalulekile ukuqaphela ukuba ifestile ende kakhulu inokungenisa ukulibaziseka ekuphenduleni utshintsho lokuhamba kokwenyani, ngoko ke kufuneka kubekho ibhalansi ngokweemfuno ezithile zesicelo.​

2. Uhlengahlengiso loMda weSignali​

• Misela ubungakanani obufanelekileyo besignali kunye nemida yefrikhwensi. Kwindawo yokuhamba kwezigaba ezininzi, iimpawu ze-ultrasonic ezifunyenwe yi-flowmeter zinokuphambuka kwiimpawu eziqhelekileyo zokuhamba kwesigaba esinye ngokwe-amplitude kunye nefrikhwensi. Ngokuhlalutya ngononophelo iimpawu eziqhelekileyo zesignali xa kukho ukuhamba kwezigaba ezininzi kwinkqubo ethile yepayipi, i-flowmeter inokulungiswa ukuba ingawunaki uphawu olungaphandle koluhlu oluchaziweyo lwemida. Oku kunceda ekususeni iimpawu zobuxoki eziveliswa ngamaqamza egesi, ukungcola, okanye iipatheni zokuhamba eziguquguqukayo ezingahambelani nokuhamba kobunzima bokwenyani bolwelo oluphambili.​

Iimodeli zeFlowmeter ezicetyiswayo zeMultiphase Flow​

1. IiDoppler Ultrasonic Flowmeters​

• IiDoppler ultrasonic flowmeters zilungele ngokukodwa ukusetyenziswa kweendlela ezininzi zokuhamba kwamanzi apho kukho amasuntswana aqinileyo okanye amaqamza egesi kulwelo. Ezi flowmeters zisebenza ngokusekelwe kwisiphumo seDoppler, esenzeka xa igagasi le-ultrasonic libonakaliswa ngamasuntswana ahambayo okanye amaqamza kulwelo. Ukutshintsha rhoqo kwegagasi elibonakalisiweyo kuhambelana nesantya sezinto ezihambayo. Umzekelo, kwisityalo sokucoca amanzi amdaka apho ukungcola kuqulethe izinto eziqinileyo ezixhonyiweyo kunye neegesi ezithile ezinyibilikisiweyo, iDoppler ultrasonic flowmeter inokulinganisa ngokuchanekileyo isantya sokuhamba kwamanzi ngokufumanisa intshukumo yezi zinto zingalinganiyo kulwelo.​

• Zenzelwe ukuphatha ulwelo ngomlinganiselo othile wokungafani kwaye zinokubonelela ngemilinganiselo yokuhamba ethembekileyo nokuba kukho inani elikhulu lamasuntswana okanye amaqamza. Ezinye ii-flowmeters ze-Doppler ultrasonic eziphambili nazo ziza nee-algorithms zokucubungula isignali ezakhiweyo ngokukodwa ezilungiselelwe iimeko zokuhamba kwezigaba ezininzi, ziphucula ngakumbi ukuchaneka kwazo kokulinganisa.​

2. Ii-Multichannel Ultrasonic Flowmeters​

• Ii-flowmeters ze-ultrasonic ezininzi zisebenzisa ii-transducers ezininzi ze-ultrasonic ezibekwe kwiindawo ezahlukeneyo ezijikeleze icandelo elinqamlezileyo lombhobho. Olu qwalaselo luvumela ukulinganiswa okubanzi ngakumbi kweprofayili yokuhamba ngaphakathi kombhobho. Kwiimeko zokuhamba kwezigaba ezininzi, ukusasazwa kokuhamba kusenokungalingani kakhulu, kunye namaqamza egesi okanye izinto ezinzima ze-slurry ezixinene kwiindawo ezithile zombhobho.​

• Ngokulinganisa isantya sokuhamba kwamanzi kwiindawo ezininzi kulo lonke ipayipi, i-multichannel ultrasonic flowmeter inokuyichaza ngcono le miba ingafaniyo kwaye ibale i-avareji yesantya sokuhamba esichanekileyo ngakumbi. Umzekelo, kumbhobho weoyile-gesi apho umxube wegesi-ulwelo unokwahlukana ube ziileya ezahlukeneyo, i-multichannel flowmeter inokulinganisa iimpawu zokuhamba kwamanzi kwileya nganye ngokwahlukeneyo ize idibanise idatha ukuze ifumane umlinganiselo ochanekileyo wokuhamba kwamanzi.​

Isiphelo​

Xa usebenza ngokuhamba kwezigaba ezininzi kwizicelo ze-ultrasonic flowmeter, ukulungiswa kweeparameter ezifana nokucoca ngokufanelekileyo kunye nokulungiswa komda wesignali kunokuphucula kakhulu ukuchaneka kokulinganisa. Ukongeza, ukukhetha imodeli ye-flowmeter efanelekileyo, njengeDoppler okanye ii-multichannel ultrasonic flowmeters, ezilungiselelwe iimeko ezithile zokuhamba kwezigaba ezininzi kunokuqinisekisa ukulinganiswa kokuhamba okuthembekileyo nokuzinzileyo.
