Isingeniso: Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe,i-gas turbine flowmetersziya ngokuya zisetshenziswa kabanzi.Ukukhetha i-flowmeter ye-turbine yegesi efanelekile kubaluleke kakhulu, ngakho-ke ungayikhetha kanjani?
I-flowmeter ye-turbine yegesi isetshenziswa kakhulu ukulinganisa ukugeleza komoya, i-nitrogen, i-oxygen, i-hydrogen, i-biogas, igesi yemvelo, umusi nolunye uketshezi oluphakathi nendawo kumapayipi ezimboni.Lapho ukala ukugeleza kwevolumu yezimo zokusebenza, cishe kuzimele ku-fluid density, ingcindezi, izinga lokushisa, i-viscosity neminye imingcele.Umthelela.Azikho izingxenye zemishini ezihambayo, ngakho-ke ukwethembeka kuphezulu futhi ukugcinwa kuncane.Amapharamitha wensimbi angasimama isikhathi eside.I-gas vortex flowmeter yamukela inzwa yokucindezeleka ye-piezoelectric, enokwethenjelwa okuphezulu futhi engasebenza ebangeni lokushisa elisebenzayo lika -20℃~+250℃.Inesignali evamile ye-analog kanye nokuphumayo kwesignali ye-digital pulse.Kulula ukuyisebenzisa ngezinhlelo zedijithali ezifana namakhompyutha.Kuyimitha yokugeleza esezingeni eliphezulu futhi ekahle.
Ngaphezu kwalokho, ukukhishwa kwesiginali ye-pulse frequency vortex flowmeter akuthintwa ukuguqulwa kwezinto ezibonakalayo eziwuketshezi kanye nokwakheka, okungukuthi, i-coefficient yemitha ihlobene kuphela nokuma nosayizi wejeneretha ye-vortex kanye nepayipi ngaphakathi kwento ethile. Ibanga lezinombolo ze-Reynolds.Kodwa-ke, njengemitha yokugeleza, kuyadingeka ukuthola ukugeleza kwenqwaba kubhalansi yezinto ezibonakalayo kanye nesilinganiso samandla.Ngalesi sikhathi, isignali yokuphuma kwemitha yokugeleza kufanele iqaphe ukugeleza kwevolumu kanye nokuminyana kwamanzi ngesikhathi esifanayo.Izakhiwo zomzimba kanye nezingxenye zoketshezi zisenomthelela oqondile esilinganisweni sokugeleza.
I-gas vortex flowmeter iwuhlobo olusha lwe-flowmeter ekala ukugeleza koketshezi kumapayipi avaliwe ngokusekelwe kumgomo we-Karman vortex.Ngenxa yokuguquguquka okuhle okuphakathi nendawo, ingakwazi ukukala ngokuqondile ukugeleza kwevolumu yesitimu, umoya, igesi, amanzi, noketshezi ngaphandle kwesinxephezelo sezinga lokushisa nokucindezela.Ifakwe izinzwa zokushisa nengcindezi, ingakwazi ukukala ukugeleza kwevolumu nokugeleza kwenqwaba ngaphansi kwezimo ezijwayelekile, ezinyakazayo.Umkhiqizo obambele okahle wohlobo lwe-flowmeter.
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, i-gas turbine flowmeters isetshenziswa kabanzi.Ukukhetha i-flowmeter ye-turbine yegesi efanelekile kubaluleke kakhulu, ngakho-ke ungayikhetha kanjani?
Okokuqala, into yokuqala okufanele uyicabangele lapho ukhetha i-flowmeter ye-turbine yegesi ukunemba kwethuluzi.Njengesici sokulinganisa, ukunemba kwe-flowmeter ye-turbine yegesi kuyisici esibaluleke kakhulu.Ukuphakama kokunemba kwe-flowmeter ye-turbine yegesi, ukuqina komugqa wokungenisa endaweni ezungezile, kanye nezimfuneko eziphezulu zemvelo.
Okwesibili, kuyadingeka ukucabangela ububanzi, obubhekisela kububanzi bokugeleza kwegesi.Uma ukugeleza kwegesi kukukhulu kakhulu, kuzodala umonakalo kulo lonke ithuluzi.Ngakho-ke, uma ibanga lokulinganisa ukugeleza okungalungile likhethiwe, lizodala umonakalo ku-flowmeter ye-turbine yegesi.Ngakho ukukhetha kusuka ebangeni lebanga nakho kuyisici esibalulekile.Okungenhla amaphuzu adinga ukunakwa lapho kukhethwa i-flowmeter ye-turbine yegesi.Uma nje lokhu kucatshangelwa kulandelwa, ungakhetha i-flowmeter ye-turbine yegesi efanele izidingo zakho zomsebenzi.
Njengethuluzi lokulinganisa ukugeleza okunembayo, lingasetshenziswa ukukala ukugeleza kanye nenani eliphelele loketshezi uma lifaniswa nesamba esihambisanayo sokugeleza.I-flowmeter ye-turbine yegesi isetshenziswa kabanzi ohlelweni lokulinganisa nokulawula lwe-petroleum, imboni yamakhemikhali, i-metallurgy, ucwaningo lwesayensi neminye imikhakha.
