Imfuneko yombhobho othe tye kwi-clamp-on ultrasonic flowmeter

Imfuneko yombhobho othe tye kwi-clamp-on ultrasonic flowmeter ingqongqo, kwaye le miyalelo ilandelayo ineenkcukacha:
Isiseko sethiyori
I-Ultrasonic flowmeter kukubala izinga lokuhamba kolwelo ngokulinganisa ixesha lokusasazeka kwe-ultrasound wave kulwelo, uze ufumane izinga lokuhamba. Ipateni yokuhamba ezinzileyo nefanayo ibalulekile ekulinganisweni ngokuchanekileyo kwexesha lokusasazeka kwe-ultrasound. Ukuba ubude becandelo lombhobho othe tye alwanelanga, ipateni yokuhamba kolwelo iya kuba yingxubakaxaka emva kokudlula kwingqiniba, ivalvu kunye nezinye izixhobo zombhobho, ezifana nee-vortices kunye nokusasazwa kwesantya sokuhamba esingalinganiyo, okuya kutshintsha indlela yokusasazeka kunye nexesha le-ultrasound wave, okubangela ukwanda kwempazamo yokulinganisa.
Iimfuno ezithile
Icandelo lombhobho othe tye phezulu
Ngokubanzi: phantsi kweemeko ezifanelekileyo zokufakela, oko kukuthi, xa kungekho okanye kukho izinto ezimbalwa zokufaka iipayipi kwinkqubo yombhobho ongaphezulu eziya kuphazamisana nepateni yokuhamba, i-external clamp ultrasonic flowmeter ifuna ukuba ubude becandelo lombhobho othe tye ongaphezulu bungabi ngaphantsi kwe-10 ubukhulu bombhobho. Umzekelo, kumbhobho onobubanzi obuyi-200mm, ubude becandelo lombhobho othe tye ongaphezulu akufuneki bube ngaphantsi kwe-2000mm. Oku kuvumela ulwelo ukuba lube nomgama owaneleyo ngaphambi kokungena kwindawo yokulinganisa ukuzinzisa imeko yokuhamba, ukuze usasazo lwesantya sokuhamba lufane, kwaye lubonelele ngeemeko ezilungileyo zentsimi yokuhamba ukuze kulinganiswe ngokuchanekileyo.
Xa kukho ukuphazamiseka kokufakelwa kwepayipi: ukuba kukho iingqiniba, ii-tee, iivalvu, iipayipi zokunciphisa kunye nezinye izixhobo zepayipi ezibangela ukuphazamiseka kokuhamba kwamanzi kumphezulu, ukuze kupheliswe impembelelo yezi zixhobo zepayipi kwimeko yokuhamba kwamanzi, ubude becandelo lepayipi elithe tye elingaphezulu kufuneka lonyuswe ngakumbi. Kwiimeko eziqhelekileyo, ubude becandelo lepayipi elithe tye kufuneka lonyuswe ukuya kuthi ga kwi-15 okanye ngama-20 ubukhulu bepayipi. Umzekelo, xa ububanzi bepayipi buyi-300mm kwaye kukho iingqiniba ezisezantsi, ubude becandelo lepayipi elithe tye elingaphezulu kunokufuneka lifikelele kwi-4500mm-6000mm. Oku kungenxa yokuba ezi zixhobo zepayipi ziya kubangela ukuba ulwelo luvelise i-whirlpool, i-drift kunye nezinye izinto zokuhamba okungacwangciswanga, kuphela ngecandelo lepayipi elide ethe tye, ukuze ulwelo luphuhliswe ngokupheleleyo kwaye lulungiswe, ukuze lubuyele kwimeko yokuhamba okuzinzileyo nokulinganayo ukuhlangabezana neemfuno zokuchaneka kokulinganisa.
Icandelo lombhobho othe tye osezantsi: Ngokubanzi, ubude becandelo lombhobho othe tye osezantsi alukho ngaphantsi kobubanzi bombhobho obuphindwe kahlanu. Kwipayipi enobubanzi obuyi-400mm, ubude becandelo lombhobho othe tye osezantsi akufanele bube ngaphantsi kwe-2000mm. Injongo yayo kukuqinisekisa ukuba ulwelo luneendawo ezaneleyo zombhobho othe tye ukugcina imeko yokuhamba ezinzileyo emva kokulinganisa, kunye nokuthintela izixhobo zombhobho osezantsi ukuba zingaphazamisi intsimi yokuhamba kwindawo yokulinganisa. Ukuba icandelo lombhobho othe tye osezantsi lifutshane kakhulu, ipateni yokuhamba kwindawo yokulinganisa inokutshintsha ngenxa yempembelelo yokufakelwa kombhobho osezantsi, ngaloo ndlela ichaphazela ukuchaneka kokulinganisa.
Iimeko ezikhethekileyo kunye namanyathelo okuchasa
Indawo encinci yentsimi: Kwezinye iimeko ezisebenzayo, ngenxa yendawo encinci yentsimi, kusenokungabi lula ukuhlangabezana neemfuno ezisemgangathweni zobude bombhobho othe tye. Ngeli xesha, amanyathelo athile okuhlawula anokuthathwa ukunciphisa impazamo yokulinganisa. Umzekelo, umlawuli wokuhamba kwamanzi unokufakelwa, onokulungisa ipateni yokuhamba kwamanzi ephazamisekileyo ukuze ulwelo lubuyele kwimeko efanayo kwaye luzinze kangangoko kunokwenzeka ngaphambi kokuba lungene kwindawo yokulinganisa. Nangona kunjalo, ukufakelwa komlawuli wokuhamba kwamanzi kufuna ubude obuthile becandelo lombhobho othe tye, okufuneka ngokubanzi ukuba necandelo lombhobho othe tye ubuncinane ngokuphindwe kathathu ububanzi bombhobho ongaphezulu kunye necandelo lombhobho othe tye ngokuphindwe kabini ububanzi bombhobho osezantsi.
Uvavanyo lweemeko zokufakela ezingezizo ezisemgangathweni: Ukuba zonke ezi meko zingasentla azinakufezekiswa kwindawo, kufuneka uvavanyo oluneenkcukacha oluvela kwingcali ngokusekelwe kulwakhiwo oluthile lombhobho, iimpawu zolwelo, uhlobo lokufakelwa kombhobho kunye nezinye izinto. Kungafuneka ukufumanisa impazamo yokulinganisa phantsi kweemeko zokufakelwa ngokulinganisa amanani, uvavanyo lwasentsimini kunye nezinye iindlela, kwaye kuthathwe amanyathelo afanelekileyo okulungisa, njengokulungisa iiSetingi zeparameter ze-flowmeter okanye ukusebenzisa ii-algorithms zokulinganisa eziphambili, ukuphucula ukuchaneka kokulinganisa kangangoko kunokwenzeka. Nangona kunjalo, phantsi kweemeko ezinjalo zokufakela ezingezizo ezisemgangathweni, kunzima ngakumbi ukufikelela kuchanekileyo lokulinganisa okufanayo nofakelo oluqhelekileyo, kwaye kuyimfuneko ukunikela ingqalelo esondeleyo kuchanekileyo lwedatha yokulinganisa kwizicelo ezisebenzayo, kwaye wenze uhlengahlengiso kunye nokugcinwa rhoqo.
