Unokukhetha njani imitha yokuqukuqela yeTurbine yegesi efanelekileyo

Intshayelelo: Ngophuhliso oluqhubekayo lwesayensi kunye nobuchwepheshe,i-flowmeters ye-injini yegesizisetyenziswa ngokubanzi nangakumbi.Ukukhetha i-flowmeter ye-turbine yegesi efanelekileyo kubaluleke kakhulu, ngoko ukhetha njani?

I-flowmeter ye-iturbine yegesi isetyenziselwa ikakhulu ukulinganisa ukuhamba komoya, i-nitrogen, ioksijini, i-hydrogen, i-biogas, igesi yendalo, umphunga kunye nolunye ulwelo oluphakathi kwimibhobho yemizi-mveliso.Xa ulinganisa umthamo wokuhamba kweemeko zokusebenza, phantse uzimele kwi-fluid density, uxinzelelo, ubushushu, i-viscosity kunye nezinye iiparitha.Impembelelo.Akukho zixhobo zomatshini ezihambayo, ngoko ukuthembeka kuphezulu kwaye ukugcinwa kuncinci.Iiparamitha zesixhobo zinokuzinza ixesha elide.I-vortex flowmeter yegesi ithatha i-piezoelectric stress sensor, enokuthembeka okuphezulu kwaye inokusebenza kwiqondo lokushisa elisebenzayo -20 ℃ ~ + 250 ℃.Inophawu oluqhelekileyo lwe-analog kunye nemveliso yedijithali yepulse.Kulula ukuyisebenzisa kwiinkqubo zedijithali ezifana neekhompyutha.Yimitha yokuqukuqela ekwinqanaba eliphezulu nefanelekileyo.

Ukongeza, i-pulse frequency signal output yi-vortex flowmeter yegesi ayichatshazelwa lutshintsho lweempawu zolwelo kunye nokwakheka, oko kukuthi, i-coefficient yemitha inxulumene kuphela nokumila kunye nobukhulu bejenereyitha ye-vortex kunye nombhobho ongaphakathi kwendawo ethile. Reynolds uluhlu lwamanani.Nangona kunjalo, njengemitha yokuhamba, kuyimfuneko ukufumanisa ukuhamba kobuninzi kwibhalansi yezinto kunye nokulinganisa amandla.Ngeli xesha, umqondiso wokuphuma kwemitha yokuhamba kufuneka ubeke iliso lokuhamba kwevolumu kunye nobuninzi be-fluid ngexesha elifanayo.Iimpawu ezibonakalayo kunye namacandelo olwelo lusenempembelelo ngqo kumlinganiselo wokuhamba.

I-gas vortex flowmeter luhlobo olutsha lwe-flowmeter elinganisa ukuhamba kolwelo kwimibhobho evaliweyo ngokusekelwe kumgaqo we-Karman vortex.Ngenxa yokuguquguquka okuhle okuphakathi, inokulinganisa ngokuthe ngqo umthamo wokuhamba komphunga, umoya, igesi, amanzi, kunye nolwelo ngaphandle kwembuyekezo yobushushu kunye noxinzelelo.Ixhotyiswe ngamaqondo obushushu kunye noxinzelelo, inokulinganisa ukuhamba kwevolumu kunye nokuhamba kobuninzi phantsi kweemeko eziqhelekileyo, ezixubhayo.Imveliso ebambeleyo efanelekileyo yohlobo lwe-flowmeter.

Ngophuhliso oluqhubekayo lwenzululwazi kunye nobuchwepheshe, ii-flowmeters ze-iturbine yegesi zisetyenziswa ngokubanzi nangakumbi.Ukukhetha i-flowmeter ye-turbine yegesi efanelekileyo kubaluleke kakhulu, ngoko ukhetha njani?

Okokuqala, into yokuqala ekufuneka uyiqwalasele xa ukhetha i-flowmeter ye-turbine yegesi kukuchaneka kwesixhobo.Njengento yokulinganisa, ukuchaneka kwe-flowmeter ye-turbine yegesi yinto ebaluleke kakhulu.Ukuphakama kokuchaneka kwe-flowmeter ye-injini yegesi, ukuqina komgca wokungeniswa kwindawo engqongileyo, kunye nokuphezulu kweemfuno zokusingqongileyo.
Okwesibini, kuyimfuneko ukuqwalasela uluhlu, olubhekiselele kuluhlu lokuhamba kwegesi.Xa ukuhamba kwegesi kukhulu kakhulu, kuya kubangela umonakalo kwisixhobo sonke.Ngoko ke, ukuba uluhlu lokulinganisa okungahambi kakuhle lukhethiwe, luya kubangela umonakalo kwi-flowmeter ye-gas turbine.Ngoko ukukhetha kuluhlu loluhlu nako yinto ebalulekileyo.Ezi zingentla ngamanqaku afuna ukuhoywa xa ukhetha i-flowmeter ye-injini yegesi.Logama nje ezi ngqwalasela zilandelwa, unokukhetha i-flowmeter ye-iturbine yegesi efanelekileyo kwiimfuno zakho zomsebenzi.

Njengesixhobo sokulinganisa ukuqukuqela okuchanekileyo, singasetyenziselwa ukulinganisa ukuhamba kunye nenani elipheleleyo lolwelo xa lifaniswa netotali ehambelanayo.I-flowmeter ye-injini yegesi isetyenziswa ngokubanzi kumlinganiselo kunye nolawulo lwenkqubo yepetroleum, ishishini lemichiza, isinyithi, uphando lwezenzululwazi kunye nezinye iinkalo.
