I-vortex flowmeter inokulinganisa ukuhamba kwegesi, ulwelo kunye nomphunga, njengokuhamba komthamo, ukuhamba kobuninzi, ukuhamba kwevolumu, njl njl.Lolona hlobo lusetyenziswa kakhulu lomlinganiselo wolwelo kwimibhobho yemizi-mveliso kwaye ineziphumo zomlinganiselo omhle.
Uluhlu lokulinganisa lwe-vortex flowmeter lukhulu, kwaye impembelelo kumlinganiselo omncinci.Ngokomzekelo, ukuxinana kwamanzi, uxinzelelo, i-viscosity, njl. akuyi kuchaphazela umsebenzi wokulinganisa we-vortex flowmeter, ngoko ke ukwenzeka kusenamandla kakhulu.
Inzuzo ye-vortex flowmeter luluhlu lwayo olukhulu lokulinganisa.Ukuthembeka okuphezulu, akukho kugcinwa komatshini, kuba akukho zixhobo zomatshini.Ngale ndlela, nokuba ixesha lokulinganisa lide, iiparamitha zokubonisa zinokuzinza.Ngenzwa yoxinzelelo, inokusebenza kwiqondo lokushisa eliphantsi kunye nendawo yokushisa ephezulu kunye nokuguquguquka okuqinileyo.Phakathi kwezixhobo zokulinganisa ezifanayo, i-vortex flowmeter iyona khetho efanelekileyo.Ngoku, iifektri ezininzi zisebenzisa olu hlobo lwesixhobo ukulinganisa ixabiso ngcono nangokuchanekileyo.
Umzekelo: 0.13-0.16 1/L, unokuqikelela i-bai ngokwakho, ulinganise ububanzi bekholamu yonxantathu, kunye ne-Straw du Hall parameter iphakathi kwe-0.16-0.23 (ibalwe kwi-0.17).
f=STV/d ifomula (1)
Apho dao:
f-Carman vortex frequency eyenziwe kwelinye icala lejenereyitha
Inombolo yaseSt-Strohal (inombolo engenamda)
V-umyinge wokuhamba kolwelo
d-ububanzi bejenereyitha ye-vortex (qaphela iyunithi)
Emva kokubala i-frequency
K=f*3.6/(v*D*D/353.7)
K: i-flow coefficient
f: Ukuphindaphinda okwenziwe ngokwesantya sokuhamba okumiselweyo
D: Umgangatho wemitha ebalekayo
V: Izinga lokuhamba
Ukukhetha uluhlu lwe-Vortex flowmeter uluhlu
Umsebenzi kunye noguqulelo lweamplifier yamandla amhlophe kunye ne-Du amandla amplifier ye-vortex flowmeter yahlukile.
