I-vortex flowmeter sisixhobo sokulinganisa ukuhamba kwamanzi esiyilwe ngokusekelwe kwinto ethi "Kármán vortex street". Xa ulwelo ludlula emzimbeni oluhlaza (i-vortex shedder) ngaphakathi kombhobho, kuveliswa imiqolo etshintshanayo yee-vortices kumacala omabini. Ngokubona i-vortex frequency nge-sensor kwaye uyidibanise neparameters ezifana nobubanzi bepayipi kunye nobuninzi bolwelo, isantya solwelo kunye nesantya sokuhamba kolwelo sinokubalwa ngokuchanekileyo.
Njengesixhobo sokulinganisa esingabizi kakhulu esibonelela ngokuchaneka okuphezulu kunye nokusetyenziswa ngokubanzi, iimitha zokuhamba kwevortex zisetyenziswa kakhulu kwiindawo zokwenza izinto ngokuzenzekelayo kwimizi-mveliso ezifana neekhemikhali, amandla, kunye nonyango lwamanzi. Nangona kunjalo, umlinganiselo we-vortex flowmeter yiizinga lokuhamba kwevolumu phantsi kwemeko yokusebenza(ubushushu bokusebenza kunye noxinzelelo). Eli xabiso lisenokungahlangabezani ngqo neemfuno zolawulo lwenkqubo kwizicelo ezininzi ezisebenzayo:
Ukulinganiswa kweGesi kunye noMphunga:Kwizinto ezixineneyo—igesi nomphunga—uxinano luchaphazeleka kakhulu kutshintsho kubushushu nakuxinzelelo. Ukwanda koxinzelelo okanye ukwehla kobushushu kukhokelela ekwandeni okukhulu koxinano, apho ukuphambuka okukhulu kunokungeniswa ngenxa yotshintsho kuxinano lokwenyani lwe-medium. Umzekelo, izinga elifanayo lokuhamba kwegesi yendalo phantsi kwemeko yoxinzelelo oluphezulu lihambelana nobunzima obukhulu kakhulu kunaphantsi koxinzelelo oluphantsi.
Iimeko ezikhethekileyo kuMlinganiselo woLwelo:Nangona ulwelo ngokubanzi luthathwa njengolungacinezelekiyo, umthamo walo usaqhubeka nokwanda okanye ukucinezelwa ngobushushu phantsi kobushushu obuphezulu okanye uxinzelelo. Kwizinto ezishushu kakhulu nezinoxinzelelo oluphezulu (ubushushu obungaphezulu kwe-100°C okanye uxinzelelo olungaphezulu kwe-10 MPa), izinto eziguquguqukayo (ezifana ne-methanol, i-ethanol), okanye izicelo ezifuna ukuchaneka okuphezulu ezifana neendlela eziphambili zokulawula inkqubo, ukungahoyi ukulungiswa kwempembelelo yobushushu kunye noxinzelelo kubuninzi bolwelo kuya kubangela iimpazamo ezibalulekileyo ngokufanayo.
Ukujongana nale ngxaki, kuyimfuneko ukubuyisela ubushushu kunye noxinzelelo kwi-vortex flowmeter. Ngokulinganisa ubushushu kunye noxinzelelo lolwelo ngexesha langempela kunye nokufaka iipropati zomzimba zolwelo, izinga lokuhamba kwevolumu yemeko yokusebenza elilinganiswe yi-vortex flow meter linokuguqulwa ngokuchanekileyo libe yi-required.izinga lokuhamba kobunzima or izinga eliqhelekileyo lokuhamba komthamo.
Indlela yesiqhelo yokuhlawula eyahlukileyo ibandakanya ukuxhobisa i-vortex flowmeter nge-sensor eyongezelelweyo yobushushu ezimeleyo (umz., i-thermometer yokumelana neplatinum) kunye ne-pressure transmitter. Ezi mpawu zintathu emva koko zifakwa kwi-flow totalizer okanye kwinkqubo yokulawula ukuze kubalwe. Olu yilo ludla ngokwandisa ubunzima bokufakelwa kunye neendleko. Ngenxa yoko, iteknoloji yokuhlawula ubushushu kunye noxinzelelo oludibeneyo iye yavela njengendlela yophuhliso. Idibanisa izinto zokuvavanya ubushushu kunye noxinzelelo oluchanekileyo kunye ne-vortex flow sensor kwiyunithi enye yokulinganisa encinci. Iingenelo zayo eziphambili ziquka:
Ukuphucula ukuLula kweNkqubo kunye noKuthembeka:Inciphisa iingcingo zangaphandle kunye nobuninzi bezixhobo ezizimeleyo, inciphisa iindleko zokufakela nokugcina izinto zisebenza kwaye iphucula ukhuseleko lwenkqubo ekuphazamisekeni nasekuzinzeni ixesha elide.
Ukuvumelanisa idatha kunye nokuqinisekiswa kokuchaneka:Izinzwa ezakhelwe ngaphakathi zilinganisa ngokuthe ngqo ubushushu bokwenyani kunye noxinzelelo lolwelo olukufutshane ne-vortex shedder, okuvumela ukufunyanwa kwenqanaba lomthombo elihambelanayo leeparameter ezininzi kunye nokuphepha iimpazamo zokuhlawula ezibangelwa kukungafani kwamanqaku okulinganisa.
Ukuhlanganiswa kweMisebenzi kunye nobuNgcali:Imodyuli yokubala edibeneyo ingasebenzisa amaxabiso obushushu kunye noxinzelelo olufunyenweyo kunye neemodeli zoxinano oluphakathi ezakhelwe ngaphakathi (ezifana ne-gas equation of state, iitafile zomphunga, okanye iifomyula zokulungisa ulwelo) ukwenza ubalo lwexesha langempela kwi-intanethi kunye nesantya sokuhamba kwevolumu esiqhelekileyo okanye isantya sokuhamba kobunzima, okuququzelela ukuhlanganiswa kwenkqubo ngokuthe ngqo nangokulula.
Imbuyekezo yobushushu kunye noxinzelelo oludibeneyo imele ukuphuculwa okubalulekileyo kokusebenza kweemitha zokuhamba kwevortex ukujongana notshintsho kwiipropati zolwelo kunye neemeko zokusebenza kunye nokufezekisa ukuguqulwa kokuhamba okuchanekileyo, ukuxhasa ngempumelelo iimfuno zolawulo lwenkqubo oluchanekileyo.Shanghai Wangyuanunamava obuchwephesha angaphezu kweminyaka engamashumi amabini kwicandelo lokuvelisa nokubonelela ngezixhobo, enikezela uluhlu olubanzi lwezixhoboiimveliso zokulinganisa ukuhamba kwamanziUkuba unayo nayiphi na imfuneko malunga nee-vortex flowmeters, siyavuya ukukunika izisombululo. Nceda uzive ukhululekile ukunxibelelana nathi nangaliphi na ixesha.
