Amamitha okugeleza ayizinto ezibalulekile ezisetshenziswa ezimbonini ezahlukene ukukala izinga lokugeleza koketshezi namagesi. Izinhlobo ezimbili ezivame kakhulu zamamitha okugeleza yileziamamitha okugeleza kokucindezela okuhlukile (DP)futhiamamitha okugeleza kwe-ultrasonicUhlobo ngalunye lunezinzuzo zalo futhi lufanelekela izinhlelo zokusebenza ezahlukene. Kulesi sihloko, sizoqhathanisa lezi zinhlobo ezimbili zamamitha okugeleza, sixoxe ngendlela ezisebenza ngayo, izinzuzo zazo, kanye nezimo zazo zokusetshenziswa ezifanele.
1. Asebenza Kanjani Amamitha Okugeleza Okucindezela Okuhlukile?
A imitha yokugeleza kwengcindezi ehlukileilinganisa izinga lokugeleza koketshezi ngokudala ukwehla kwengcindezi endaweni evinjelwe ukugeleza (njengepuleti le-orifice, ithubhu le-venturi, noma i-flow nozzle). Isimiso salolu hlobo lwemitha sisekelwe kuIsimiso sikaBernoulli, okusho ukuthi njengoba ijubane loketshezi likhuphuka, ukucindezela kwalo kuyehla.
Isimiso Sokusebenza:
- A ukuvinjelwa(isb., ipuleti lomgodi) libekwa endleleni yokugeleza, okubangela ukwehla kwengcindezi.
- Imitha ilinganisa umehluko ekucindezelweni ngaphambi nangemuva kokuvinjelwa (iingcindezi yokwehluka).
- Isebenzisa ubudlelwano phakathi kokwehla kwengcindezi kanye nesilinganiso sokugeleza, imitha yokugeleza ibala izinga lokugeleza isebenzisa amafomula ezibalo noma ama-calibration curves.
Ukucindezela okuhlukile kuhlobene ngqo nejubane loketshezi, okuvumela imitha ukubala izinga lokugeleza.
2. Asebenza Kanjani Amamitha Okugeleza E-Ultrasonic?
An imitha yokugeleza kwe-ultrasonicisebenzisa amaza omsindo (amaza e-ultrasonic) ukukala izinga lokugeleza koketshezi noma igesi. Kunezinhlobo ezimbili eziyinhloko zamamitha okugeleza e-ultrasonic:isikhathi sokuhambafuthiI-DopplerAmamitha e-ultrasonic e-transit-time avame ukusetshenziswa kakhulu koketshezi oluhlanzekile nolufanayo, kuyilapho amamitha e-Doppler esetshenziswa koketshezi oluqukethe izinhlayiya ezilengayo noma amabhamuza.
Isimiso Sokusebenza:
- Amamitha e-ultrasonic esikhathi sokuthuthathumela ama-pulse e-ultrasonic phezulu nangezansi ngoketshezi. Ngokuqhathanisa isikhathi esithathwa ama-pulse ukuhamba kuzo zombili izinhlangothi, izinga lokugeleza linqunywa ngokusekelwe kumehluko wesikhathi obangelwa yijubane lokugeleza.
- Amamitha e-Doppler ultrasoundsebenza ngokulinganisa ukushintshashintsha kwemvamisa kwamagagasi omsindo abonakala ezinhlayiyeni noma amabhamuza oketshezini. Izinga lokugeleza linqunywa ngokusekelwe kubukhulu balokhu kushintshashintsha kwemvamisa.
Ama-flow metres e-Ultrasonic awadingi izingxenye ezihambayo futhi avame ukufakwa ngaphandle epayipini, okwenza afaneleke kakhulu ekulinganisweni kokugeleza okungangenisi umswakama.
3. Izinzuzo Zamamitha Okugeleza Okucindezela Okuhlukile
Amamitha okugeleza kokucindezela okuhlukile asetshenziswe kabanzi iminyaka eminingi futhi athembekile ngokuthembeka kwawo ezinhlotsheni ezahlukene zokusebenza. Ezinye zezinzuzo ezibalulekile zifaka:
a. Ubuchwepheshe Obusungulwe Kahle
- Amamitha okugeleza kokucindezela okuhlukile abelokhu esetshenziswa amashumi eminyaka futhi awubuchwepheshe obusekelwe kahle. Avame ukusetshenziswa ezimbonini ezifana nowoyela negesi, ukucubungula amakhemikhali, kanye nokwelashwa kwamanzi.
b. Ukunemba Okuphezulu Koketshezi Namagesi
- Zinikeza izilinganiso zokugeleza ezithembekile nezinembile zezinhlobo eziningi zoketshezi namagesi, ikakhulukazi lapho ukugeleza kuzinzile futhi kubikezelwa.
c. Iqinile futhi Ingabizi Kakhulu
- Lawa mamitha avame ukuqina futhi angamelana nokucindezeleka okuphezulu kanye namazinga okushisa, okwenza afaneleke kakhulu ezindaweni zezimboni ezinzima.
- Ngokuvamile zisebenza kahle kakhulu kunezinye izinhlobo zamamitha okugeleza.
d. Kufanelekela Ama-High-Viscosity Fluids
- Amamitha okugeleza kokucindezela okuhlukile asebenza kahle ngoketshezi olune-viscosity ephezulu, njengamafutha noma ama-slurries, lapho amanye amamitha okugeleza angase abe nenkinga khona.
4. Izinzuzo zama-Ultrasonic Flow Meters
Amamitha okugeleza e-Ultrasonic athole ukuthandwa eminyakeni yamuva ngenxa yobuchwepheshe bawo obuthuthukisiwe kanye nezindlela zokulinganisa ezingangenisi umswakama. Nazi ezinye izinzuzo ezibalulekile:
a. Ukulinganisa Okungahlaseli
- Ama-Ultrasonic flow metres angafakwa ngaphandle epayipini, ngaphandle kokuthintana noketshezi, okwenza kube kuhle kakhulu ukusetshenziswa lapho ukungcola kufanele kugwenywe khona, noma uketshezi kunzima ukulufinyelela.
b. Azikho Izingxenye Ezinyakazayo
- Njengoba amamitha e-ultrasonic engenazo izingxenye ezihambayo, anezidingo zokunakekelwa eziphansi uma kuqhathaniswa namanye amamitha okugeleza afana namamitha okucindezela ahlukile, avame ukuthembela ezingxenyeni ezihambayo (isb., amapuleti e-orifice).
c. Kufanelekela uketshezi oluhlanzekile nolungahlanzekile
- Amamitha okugeleza kwe-ultrasonic ngesikhathi sokuthuthazilungele kakhulu uketshezi oluhlanzekile nolufanayo njengamanzi, amakhemikhali, namafutha.Amamitha e-Doppler ultrasoundingasetshenziswa ezintweni eziqukethe izinto eziqinile ezilengayo noma amabhamuza egesi, njengamanzi angcolile noma i-slurry.
d. Ukunemba Okuphezulu
- Amamitha okugeleza e-Ultrasonic anikeza ukunemba okuphezulu futhi asebenza kahle kakhulu ekulinganiseni amazinga okugeleza aphansi. Ayakwazi futhi ukubona izinguquko ezincane kakhulu ekugelezeni, okwenza kube kuhle kakhulu ekusetshenzisweni okunembile.
e. Akukho Ukulahlekelwa Yingcindezi
- Ngokungafani namamitha okucindezela ahlukene, abangela ukwehla kwengcindezi ngenxa yokuvinjelwa kwendlela yokugeleza, amamitha okugeleza e-ultrasonic awaphazamisi ukugeleza futhi awathinti ingcindezi yoketshezi.
5. Ukuqhathanisa: Nini Ukusebenzisa Imitha Yokugeleza Ngayinye
Amamitha Okugeleza Okucindezela Okuhlukile Afaneleka Uma:
- Udinga ukukala ukugeleza kwezinhlelo ezinengcindezi ephezulu noma izinga lokushisa eliphezulu.
- Uketshezi luvame ukuhlanzeka noma lufana, futhi izinga lokugeleza lizinzile.
- Ubhekene noketshezi noma amagesi anokugcwala okuphezulu, lapho ezinye izinhlobo zamamitha zingase zingasebenzi kahle.
- Udinga ikhambi eliqinile nelingabizi kakhulu lezinhlelo zokusebenza zezimboni.
Ama-Ultrasonic Flow Meters Afaneleka Uma:
- Udinga ukulinganisa okungangenisi uketshezi ngaphandle kokuphazamisa ukugeleza noma ukuthintana ngokomzimba noketshezi.
- Ulinganisa uketshezi noma amagesi ahlanzekile, noma usebenzisa i-Doppler ultrasonic flow meter ukukala uketshezi ngezinhlayiya ezilengayo noma amabhamuza.
- Udinga ukulinganisa ukugeleza okunembe kakhulu, ikakhulukazi uma kusetshenziswe ukugeleza okuphansi.
- Ufuna imitha enezidingo ezincane zokulungisa futhi engenawo umfutho owehlayo.
6. Isiphetho
Kokubiliamamitha okugeleza kokucindezela okuhlukilefuthiamamitha okugeleza kwe-ultrasoniczingamathuluzi asebenza kahle kakhulu okulinganisa ukugeleza, kodwa zilungele kakhulu izinhlelo zokusebenza ezahlukene.
- Amamitha okugeleza kokucindezela okuhlukilekuyisinqumo esihle kakhulu sezinhlelo ezinomfutho ophezulu, uketshezi olunamandla aphezulu, kanye nezindawo zezimboni zendabuko lapho ukusebenza kahle kwezindleko kanye nokuthembeka kubalulekile khona.
- Amamitha okugeleza e-Ultrasoniczinikeza inzuzo yokulinganisa okungangenisi ukungcola, ukunemba okuphezulu, kanye nokugcinwa okuncane, okwenza kube kuhle kakhulu ezikhungweni ezihlanzekile, ezimweni zokugeleza okuphansi, kanye nokusetshenziswa lapho ukulahleka kwengcindezi kufanele kugwenywe khona.
Ukuqonda umehluko nezinzuzo zala mamitha okugeleza amabili kuzokusiza ukuthi ukhethe inketho engcono kakhulu yezidingo zakho ezithile zokulinganisa ukugeleza.
