1. Ukungenzeka kwe-Ultrasonic Flowmeters yezixazululo ze-Acidic/Alkaline
Yebo, ama-flowmeter e-ultrasonic angalinganisa ngempumelelo izixazululo ze-acidic ne-alkaline, kodwa ukufaneleka kwawo kuncike kakhulu ekukhethweni kwezinto ze-transducer kanye nohlobo lokufakwa—izici ezimbili ezibhekana ngqo nohlobo lokugqwala kwalezi zinhlayiya. Ngokungafani namamitha angena ngaphakathi (isb., ama-flowmeter e-electromagnetic anama-electrode angaphakathi) abeka engcupheni ukugqwala ngenxa yokuxhumana ngqo nama-acid/izisekelo ezinamandla, ama-flowmeter e-ultrasonic (ikakhulukazi amamodeli e-clamp-on) anciphisa ukuxhumana koketshezi ngokufaka ama-transducer ngaphandle kwepayipi. Kuma-flowmeter e-ultrasonic asemgqeni (lapho ama-transducer exhumana khona nesixazululo), ukusebenzisa izinto ezingamelani nokugqwala njenge-PTFE (polytetrafluoroethylene), i-ceramic, noma i-Hastelloy kuqinisekisa ukuhambisana noketshezi olunamandla njenge-sulfuric acid, i-hydrochloric acid, noma i-sodium hydroxide. Uma nje izinto ze-transducer zihambisana nokugqwala kwesisombululo kanye nezinto zepayipi (isb., i-PVC, i-PVDF yezinhlayiya ze-acidic) kuyahambisana, ama-flowmeter e-ultrasonic agcina ukusebenza okuzinzile ngaphandle kokuwohloka.
2. Izinzuzo Eziyinhloko Kunemitha Yendabuko Yoketshezi Olugqwalisayo
Ama-flowmeter e-Ultrasonic anikeza izinzuzo eziyingqayizivele lapho elinganisa izixazululo ze-acidic/alkaline, ebhekana nezinkinga zobuchwepheshe bokulinganisa bendabuko:
- Akukho Ukuguga Okubangelwa Ukugqwala: Ngokungafani nama-flowmeter omshini (isb., amamitha e-turbine) anezingxenye ezihambayo ezigqwala futhi zijame, noma amamitha kagesi anama-electrode ensimbi avame ukuhlaselwa yi-acid/alkali, ama-flowmeter e-ultrasonic (i-clamp-on) awanazo izingxenye ezithintana ngqo nesisombululo. Amamodeli asemgqeni asebenzisa izinto ezingasabeli, aqeda ukulahleka kokunemba okuhlobene nokugqwala noma ukwehluleka kwedivayisi.
- Akuthinteki Ukuhanjiswa Kwe-Fluid: Izixazululo ze-asidi kanye ne-alkaline ziyahlukahluka kakhulu ekuhanjisweni (isb., i-acetic acid encibilikisiwe inokuhanjiswa okuphansi, kuyilapho i-sodium hydroxide egxilile inokuhanjiswa okuphezulu). Ama-flowmeter e-electromagnetic athembele ekuhanjisweni koketshezi ukuze asebenze futhi angase ahluleke ngama-acid angaphansi kokuhanjiswa, kodwa ama-flowmeter e-ultrasonic alinganisa ukugeleza ngokusabalala kwamagagasi omsindo—ukuhanjiswa, i-viscosity, noma ukwakheka kwamakhemikhali kwesisombululo akuphazamisi ukufundwa kwawo.
- Ukugcinwa Okuncane: Uketshezi olugqwalisayo luvame ukubangela ukugcinwa njalo kwamamitha avamile (isb., ukufaka esikhundleni ama-electrode agqwalile noma izingxenye zemishini). Ama-flowmeter e-Ultrasonic, angenazo izingxenye ezihambayo noma izingxenye ezigqwalayo, adinga ukuhlolwa ngezikhathi ezithile kuphela kokulungiswa kwe-transducer noma isimo sodonga lwepayipi, okunciphisa isikhathi sokungasebenzi kanye nezindleko zokulungisa.
3. Izinto Ezibalulekile Okufanele Zicatshangelwe Ukuze Kulinganiswe Ngokwethembeka
Ukuqinisekisa ukulinganiswa okunembile nokwesikhathi eside kwezixazululo ze-asidi/i-alkaline, izici ezintathu ezibalulekile kumele zibekwe phambili:
- Ukuhambisana Kwezinto Ze-Transducer: Khetha izinto ngokusekelwe emandleni kanye nohlobo lwesisombululo. Isibonelo, i-PTFE isebenza kuma-asidi amaningi aqinile (ngaphandle kwe-hydrofluoric acid egxilile eshisayo), kuyilapho ama-transducer e-ceramic ephatha izixazululo ze-alkaline ezishisa kakhulu (isb., i-sodium hydroxide engu-80°C). Gwema ukusebenzisa ama-transducer ensimbi (isb., insimbi engagqwali) ukuze uthole uketshezi oluqinile olubolayo, njengoba luzowohloka ngokuhamba kwesikhathi.
- Isimo Sepayipi Nezinto Ezisetshenziswayo: Ipayipi ngokwalo kumele imelane nokugqwala—izinketho ezivamile zifaka phakathi i-PVDF (yama-asidi aqinile), i-PVC (yama-asidi/izisekelo ezithambile), noma insimbi efakwe ingilazi (yama-fluid agqwalisayo ashisa kakhulu). Udonga lwepayipi olulimele noma olugqwalile lungaphazamisa amasignali e-ultrasonic, okuholela emaphutheni okulinganisa; qinisekisa ukuthi ipayipi liphelele futhi linobuso obubushelelezi bangaphakathi.
- Imikhawulo Yokushisa Nokucindezela: Ama-asidi/izisekelo ezinamandla zingasebenza emazingeni okushisa aphezulu (isb., i-sulfuric acid yezinga lezimboni ku-60–80°C) noma ukucindezela. Qinisekisa ukuthi ububanzi bokusebenza be-ultrasonic flowmeter buhambisana nokushisa nokucindezela kwesisombululo—ukudlula le mikhawulo kungalimaza ama-transducer noma kunciphise ukunemba kwesignali. Ngezinhlelo zokusebenza zokushisa okuphezulu, khetha ama-transducer amelana nokushisa okuphezulu (isb., amamodeli e-ceramic alinganiselwe kufika ku-150°C).
Isifinyezo
Ama-flowmeter e-Ultrasonic ayisinqumo esisebenzayo nesithembekile sokulinganisa izixazululo ze-acidic ne-alkaline, uma nje izinto ze-transducer zihambisana nokugqwala koketshezi, futhi izimo zamapayipi zihlangabezana nezidingo eziyisisekelo. Ukwakheka kwazo okungaphazamisi (kwamamodeli okubopha) noma izingxenye eziku-line ezingamelani nokugqwala, kuhlanganiswe nokungavikeleki ekuqhutshweni koketshezi, kuzenza zibe ngcono kunamamitha endabuko ezindaweni ezigqwalisayo. Ngokubhekana nokuhambisana kwezinto, isimo sepayipi, kanye nemikhawulo yokusebenza, ama-flowmeter e-ultrasonic anikeza isilinganiso sokugeleza okunembile, okunganakekelwa kahle kwezicelo zamanzi ezimboni, amakhemikhali, noma amanzi angcolile ahilela uketshezi lwe-acidic/alkaline.
