Okwamanje, konke okwethu Transit-Time ultrasonic flow metreszisetshenziselwa ukulinganisa ukugeleza koketshezi futhi Ipayipi elilinganisiwe kufanele libe yipayipi lamanzi eligcwele.Imitha yokugeleza koketshezi lwesikhathi sokuthutha evame ukusetshenziswa ezitshalweni zokuphakela amanzi, isicelo se-HVAC, imboni yemithi, imboni yokudla, imboni yesiphuzo, imboni ye-metallurgy nokunye.I-Flowmeter yethu ye-ultrasonic ye-Transit-Time ingahlukaniswa ibe imitha yokugeleza ye-ultrasonic yesiteshi esisodwa, imitha yokugeleza ye-ultrasonic ye-Dual-channel, imitha yokugeleza ye-ultrasonic yamashaneli amaningi.
Imitha yokugeleza ye-ultrasonic yesiteshi esisodwangepheya elilodwa le-clamp noma izinzwa zokufaka
Iziteshi eziphindwe kabili imitha yokugeleza ye-ultrasonicenamapheya amabili ezinzwa zokuqinisa noma zohlobo lokufaka
Imitha yokugeleza ye-ultrasonic yokufakwa kwamashaneli amaningi enamapheya angu-4 ezinzwa zokufaka
Zilungele ukukala uketshezi oluhlanzekile oluhlobene, uketshezi oluqukethe izinto eziqinile,ukunemba kungafinyelela ku-1%, ukunemba kwe-flual channel ultrasonic flowmeter kungaba kufika ku-0.5%.
Embonini yamakhemikhali, ukuhlanza amanzi, uphethiloli kanye nezinye izimboni zizosebenzisa ama-flowmeters ukukala izinhlobonhlobo zoketshezi, njengoketshezi lwamakhemikhali, amanzi ompompi, amanzi ezimboni, amanzi angcolile asekhaya nokunye.Futhi kwezokwelapha, ukudla kanye nezinye izimboni, ngokuvamile banezindinganiso eziqinile kukhwalithi yamanzi ukuze kulinganiswe ukugeleza , badinga ukukala ukugeleza kwamanzi ahlanzekile noma amanzi ahlanzekile kakhulu, ukuqhutshwa kwamanzi okuhlanzekile kuzoba kuncane kakhulu.
Kungani ukubopha ohlotsheni lwesikhathi sokuhamba i-ultrasonic flowmeter kuyisixazululo esingcono kakhulu sokulinganisa uketshezi oluhlanzekile?
Ake ngithathe ezinye izinhlobo ze-flow meter ezidumile njengesiqhathaniso.
1. I-electromagnetic flowmeter
I-flowmeter ye-electromagnetic isekelwe emthethweni kaFaraday wokungeniswa kuka-electromagnetic.Isetshenziselwa ukukala ukugeleza kwevolumu yoketshezi olusebenzayo olunomthamo omkhulu kuno-5μS/cm.Kuyimitha ye-inductive yokulinganisa ukugeleza kwevolumu ye-conductive medium.
Le mitha ingasetshenziswa ukukala ukugeleza kwevolumu yoketshezi olunamandla oludlayo olufana ne-asidi eqinile nesisekelo esiqinile kanye noketshezi olumisiwe olunezigaba ezimbili olumisiwe olufana nodaka, i-pulp nephepha.Njengoba i-conductivity yamanzi ahlanzekile ingu-0.055 μS/cm kuphela, iphansi kakhulu kuno-5μS/cm, kusobala ukuthi ama-flowmeters kagesi awafanele ukukalwa kwalolu ketshezi.
2. I-Turbine flowmeter
Amamitha okugeleza kwe-turbine asebenzisa amandla emishini oketshezi ukuzungezisa i-rotor ngaphakathi komfudlana wokugeleza.Isivinini sokujikeleza silingana ngokuqondile nesivinini soketshezi oluhamba ngemitha.
Kuyabonakala ukuthi i-turbine flowmeter iyisilinganiso sokugeleza kokuxhumana, futhi amanzi ahlanzekile anezidingo eziphakeme kakhulu zezinto ezibonakalayo, ngakho-ke impahla eyinhloko kufanele isetshenziswe ekukhiqizeni i-316L, ukusetshenziswa kwe-sanitary clamp joint, izindleko zokukhiqiza zanda kakhulu.
3. Vi-ortex flow meter,I-Turbine flowmeter, imitha yokugeleza kwePD
Amamitha okugeleza kwe-Vortex, evame ukubizwa ngokuthi amamitha okugeleza okuchithwa kwe-vortex, sebenzisa isithiyo kumfudlana wokugeleza ukuze udale ama-vortices akheka ngokushintshana nhlangothi zombili zesivimbelo.Njengoba la ma-vortice ephela esivimbelweni, adala izindawo ezishintshanayo eziphansi nezinomfutho ophezulu ozungeza kumaza athile ngokulingana ngokuqondile nesivinini soketshezi.Izinga lokugeleza lingabalwa ngesivinini soketshezi.
I-turbine flow metresukusetshenziswa noketshezi kunethiyori yokusebenza elula uma kuqhathaniswa, njengoba uketshezi lugeleza kushubhu lemitha yokugeleza luthinta ama- turbine blades.Ama-turbine blades ku-rotor ayajika ukuze aguqule amandla asuka oketshezini olugelezayo abe amandla ajikelezayo.I-shaft ye-rotor ijikeleza kuma-bearings, njengoba isivinini soketshezi sikhulisa ukujikeleza kwe-rotor ngokushesha.Ukuguquguquka ngomzuzu noma i-RPM ye-rotor ilingana ngokuqondile nesivinini sokugeleza kwesilinganiso ngaphakathi kobubanzi beshubhu lokugeleza futhi lokhu kuhlobene nevolumu ebangeni elibanzi.
Positive displacement flow metressebenzisa amagiya amabili anelungelo lobunikazi (amagiya) ukukala amavolumu anembayo oketshezi oludlula kumitha yokugeleza njengoba amagiya ezungeza.Lawa mamitha okugeleza aklanyelwe ngokuqondile ukukala ngokunembile uketshezi olujiyile njengama-resin, ama-polyurethanes, izinto zokunamathisela, opende, namakhemikhali e-petrochemicals ahlukahlukene.
Ziyisilinganiso sokugeleza koketshezi lohlobo lokuxhumana, ngakho-ke zizothintana ngqo noketshezi, oluzongcolisa uketshezi olulinganisiwe.
4. I-Coriolis Mass Flowmeter
Imitha yokugeleza ye-Coriolis iqukethe ishubhu elinikwa amandla ukudlidliza okungaguquki.Uma uketshezi (igesi noma uketshezi) ludlula kuleli shubhu umfutho wokugeleza kwenqwaba uzodala ushintsho ekudlidlizeni kweshubhu, ishubhu lizosonteka okuholela ekushintsheni kwesigaba.Lokhu kushintsha kwesigaba kungakalwa bese okukhiphayo ngomugqa kuthathwe ngokulingana nokugeleza.
Njengoba isimiso se-Coriolis sikala ukugeleza kwenqwaba ngaphandle kwalokho okungaphakathi kweshubhu, singasetshenziswa ngokuqondile kunoma iluphi uketshezi olugeleza kulo - LIQUID noma i-GAS - kuyilapho amamitha okugeleza kwesisindo esishisayo ancike ezintweni ezibonakalayo zoketshezi.Ngaphezu kwalokho, ngokuhambisana nokushintshwa kwesigaba sokuvama phakathi kokuphumayo nokuphumayo, kuyenzeka futhi ukukala uguquko lwangempela lwemvamisa yemvelo.Lolu shintsho lwemvamisa lulingana ngqo nokuminyana koketshezi - futhi ukuphuma kwesignali okwengeziwe kungatholwa.Ngemva kokukala kokubili izinga lokugeleza okukhulu kanye nokuminyana kungenzeka ukuthola izinga lokugeleza kwevolumu.
Namuhla, le mitha ilungile ukukala ipayipi elingu-200mm noma ngaphansi, ayikwazi ukukala ipayipi elikhulu lobubanzi;Ngaphezu kwalokho, inkulu ngesisindo nomthamo, akulula ukuyiphatha.
Ukuze uthole isilinganiso sokugeleza kwamanzi ahlanzekile, ungakhetha imitha yokugeleza ngokusekelwe kulawa mazinga alandelayo.
1) Ukukhetha imitha yokugeleza kwamanzi yohlobo olungangeneleli futhi ungathintani ngokuqondile noketshezi olulinganisiwe ukuqinisekisa ukuthi uketshezi alungcolisiwe;
2) I-flowmeter ekhethiwe kufanele ikwazi ukukala uketshezi nge-conductivity ephansi kakhulu.
3) Ukufakwa kanye nedatha yokulinganisa yemitha yokugeleza ngeke ithintwe ububanzi bepayipi elilinganisiwe.
I-clamp yangaphandle ku-flowmeter ye-ultrasonic iwuhlobo lwemitha yokugeleza kwe-liquid engathinteki, ingakwazi ukukala ipayipi ukusuka ku-20mm kuya ku-5000mm, ububanzi obubanzi bepayipi, futhi ingasetshenziswa ukukala uketshezi okunzima ukuthintana nalo nokubukwa.Ukunemba kuphakeme uma kuqhathaniswa, cishe akukho ukuphazamiseka kwezinto ezibonakalayo ezihlukahlukene zendawo elinganisiwe, njengokugqwala okuqinile, okungaqhubeki, okunemisebe, uketshezi oluvuthayo nokuqhuma nezinye izinkinga.Ngakho-ke, ngesilinganiso samanzi ahlanzekile, sizoqale sincome i-clamp-on fluid ultrasonic flowmeter ukukala.
Bonisa izimo ezithile zangempela zereferensi yakho.
