1. Chiyambi
Ma flowmeter a ultrasonicamagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kusalowerera kwawo, kulondola kwambiri, komanso kuthekera koyesa kuchuluka kwa madzi osiyanasiyana. Komabe, magwiridwe antchito a ultrasound flowmeters amatha kukhudzidwa kwambiri ndi mawonekedwe a mapaipi. Nkhaniyi ikufotokoza momwe zipangizo zosiyanasiyana za mapaipi zimakhudzira ntchito ndi kulondola kwa ultrasound.zoyezera kuyenda.
2. Mfundo Yogwirira Ntchito ya Ma Ultrasonic Flowmeters
Ma flowmeter a ultrasonicamagwira ntchito motsatira mfundo yoyezera kusiyana kwa nthawi pakati pa zizindikiro za ultrasonic zomwe zikuyenda mmwamba ndi pansi mu madzi. Transit - nthawi ya ultrasonic flowmeters imayesa nthawi yomwe mafunde a ultrasound amayendera mbali zonse ziwiri. Liwiro la kuyenda kwa madzi limawerengedwa kutengera kusiyana kwa nthawi kumeneku. Kumbali ina, ma Doppler ultrasonic flowmeters amadalira Doppler effect. Amayesa kusintha kwa mafunde a ultrasound omwe amawonetsedwa kuchokera ku tinthu tating'onoting'ono kapena thovu mu madzi oyenda.
3. Zotsatira za Zipangizo Zomangira Mapaipi
3.1 Zipilala Zachitsulo
Zipinda zachitsulo, monga chitsulo chosapanga dzimbiri kapena aluminiyamu, zimawala kwambiri ndi mafunde a ultrasonic. Zizindikiro za ultrasonic zikakumana ndi zipinda zachitsulo, gawo lalikulu la mphamvu ya mafunde limawalanso. Kuwala kumeneku kungayambitse kusokonezeka kwa zizindikiro zotumizidwa ndi zolandiridwa mu ma ultrasound flowmeters. Mwachitsanzo, m'mafakitale komwe mapaipi okhala ndi zipinda zachitsulo amagwiritsidwa ntchito kunyamula madzi owononga, kuwala kwamphamvu kuchokera ku zipinda kungayambitse kuyeza kolakwika kwa nthawi - ya - kuuluka kapena kusintha kwa Doppler. Zotsatira zake, kuchuluka kwa kuyenda komwe kwawerengedwa kumatha kusiyana ndi mtengo weniweni.
3.2 Mapepala a Rabala
Ma linens a rabara amadziwika ndi kusinthasintha kwawo komanso kukana dzimbiri bwino. Komabe, ali ndi acoustic attenuation yapamwamba kwambiri. Mafunde a ultrasound amataya mphamvu zambiri akamadutsa mu linens za rabara. Kuchepetsa kumeneku kumatha kuchepetsa chiŵerengero cha chizindikiro mpaka phokoso mu ultrasoundzoyezera kuyendaMu makina okhala ndi mipata yokhuthala ya raba, zizindikiro za ultrasound zomwe zimalandiridwa zingakhale zofooka kwambiri kuti zisayese molondola magawo a kayendedwe ka madzi. Mwachitsanzo, m'malo oyeretsera madzi otayira komwe mapaipi okhala ndi mipata ya raba ndi ofala, kuchepa kwambiri kwa mafunde a ultrasound kungayambitse zolakwika muyeso, makamaka poyesa kuchuluka kwa madzi otayira.
3.3 Mapepala apulasitiki
Mapepala apulasitiki, monga polyethylene (PE) ndi polyvinyl chloride (PVC), ali ndi mphamvu zosiyanasiyana zoyatsira mawu. Mapulasitiki ena ali ndi mphamvu yochepa yoyatsira mawu, zomwe zingayambitse kusinthasintha kwakukulu kwa mafunde a ultrasound pamalo olumikizirana pakati pa khoma la chitoliro ndi khomalo. Kusinthasintha kumeneku kumatha kusokoneza njira ya zizindikiro za ultrasound, zomwe zimapangitsa kuti zikhale zovuta kwachoyezera kayendedwe ka madzikuyeza molondola nthawi - ya - kuuluka kapena kusintha kwa Doppler. Kuphatikiza apo, ma pulasitiki amatha kuyamwa mphamvu inayake ya ultrasound, zomwe zimapangitsa kuti mphamvu ya chizindikiro ichepe kwambiri. Mwachitsanzo, m'makina othirira omwe amagwiritsa ntchito mapaipi okhala ndi PVC, kupendekeka ndi kuyamwa kwa mafunde a ultrasound ndi ma membrane kungayambitse kuyeza kolakwika kwa madzi.
3.4 Mapepala a Ceramic
Zipinda za ceramic nthawi zambiri zimagwiritsidwa ntchito m'malo otentha komanso owuma chifukwa cha kutopa kwawo komanso kutentha kwambiri. Komabe, zipangizo za ceramic zimakhala ndi mphamvu yayikulu yotulutsa mawu, zomwe zingayambitse kuwunikira kwamphamvu kwa mafunde a ultrasound. Mofanana ndi zipinda zachitsulo, kuwunikira kuchokera ku zipinda za ceramic kumatha kusokoneza magwiridwe antchito abwinobwino a ma ultrasound flowmeters. M'mafakitale monga migodi ndi kupanga simenti, komwe mapaipi okhala ndi zipinda za ceramic amagwiritsidwa ntchito kunyamula matope owuma, kuwunikira kwamphamvu kwa mafunde a ultrasonic kuchokera ku zipinda za ceramic kungayambitse kuyeza kosadalirika kwa kayendedwe ka madzi.
4. Njira Zochepetsera Vutoli
Kuti muchepetse mphamvu ya mapaipi pa ma flowmeter a ultrasonic, njira zingapo zitha kugwiritsidwa ntchito. Njira imodzi ndiyo kusankha mtundu woyenera wa flowmeter ya ultrasonic kutengera mawonekedwe a payipi. Mwachitsanzo, m'mapaipi okhala ndi ma linings owunikira kwambiri, ma flowmeter a ultrasonic a mtundu wa Doppler angakhale oyenera kwambiri chifukwa sakhudzidwa kwambiri ndi signal reflection. Njira ina ndiyo kukonza bwino kuyika kwa flowmeter. Izi zikuphatikizapo kuonetsetsa kuti ma transducer a ultrasonic akugwirizana bwino ndikusankha malo oyenera oyika kuti muchepetse mphamvu ya lining - yokhudzana ndi signal corruption. Kuphatikiza apo, njira zamakono zopangira ma signal zitha kugwiritsidwa ntchito kuti ziwongolere kulondola kwa miyeso ya flow pamaso pa ma linings a mapaipi.
5. Mapeto
Zipangizo za mapaipi zimagwira ntchito yofunika kwambiri pakugwira ntchito kwa ma ultrasound flowmeter. Zipangizo zosiyanasiyana zapaipi, monga zitsulo, rabara, pulasitiki, ndi ceramic, zimatha kukhala ndi zotsatira zosiyanasiyana pa zizindikiro za ultrasound, kuphatikizapo kuwunikira, kuchepetsa, ndi kusinthasintha. Kumvetsetsa zotsatira izi ndikugwiritsa ntchito njira zoyenera zochepetsera ndikofunikira kuti zitsimikizire kuyeza kolondola komanso kodalirika kwa kayendedwe ka madzi m'mafakitale. Mwa kuganizira mosamala za mawonekedwe a mapaipi ndikusankha ultrasound flowmeter yoyenera komanso njira yoyikira, mafakitale amatha kukonza magwiridwe antchito awo.muyeso wa kayendedwe ka madzimachitidwe.
