Selelekela: Ka tsoelopele e tsoelang pele ea mahlale le thekenoloji,li-flowmeters tsa turbine ea khaseli sebelisoa haholo le ho feta.Ho khetha phallo ea turbine ea khase e loketseng ke ea bohlokoa haholo, joale u ka khetha joang?
Phallo ea turbine ea khase e sebelisoa haholo-holo bakeng sa tekanyo ea phallo ea moea, naetrojene, oksijene, hydrogen, biogas, khase ea tlhaho, mouoane le maro a mang a mahareng liphaepheng tsa indasteri.Ha u lekanya phallo ea molumo oa maemo a ho sebetsa, e batla e ikemetse ka bongata ba mokelikeli, khatello, mocheso, viscosity le likarolo tse ling.Tšusumetso.Ha ho na likarolo tsa mechine tse tsamaeang, kahoo ho tšepahala ho phahame 'me tlhokomelo e nyenyane.Lisebelisoa tsa lisebelisoa li ka tsitsa ka nako e telele.The gas vortex flowmeter e amohela piezoelectric stress sensor, e nang le ts'epo e phahameng mme e ka sebetsa maemong a mocheso a sebetsang a -20 ℃~+250 ℃.E na le lets'oao le tloaelehileng la analog le tlhahiso ea lets'oao la dijithale.Ho bonolo ho e sebelisa le lisebelisoa tsa digital tse kang lik'homphieutha.Ke meter ea phallo e batlang e tsoetse pele ebile e loketse.
Ntle le moo, tlhahiso ea lets'oao la pulse frequency vortex flowmeter ha e amehe ke phetoho ea thepa ea 'mele le sebopeho sa mokelikeli, ke hore, coefficient ea mitha e amana feela le sebopeho le boholo ba jenereithara ea vortex le phaepe ka har'a ntho e itseng. Reynolds palo e fapaneng.Leha ho le joalo, joalo ka meter ea phallo, hoa hlokahala ho lemoha phallo ea bongata ho leka-lekana ha thepa le tekanyo ea matla.Ka nako ena, pontšo ea phallo ea meter ea phallo e lokela ho shebella phallo ea molumo le boima ba metsi ka nako e le 'ngoe.Lintho tsa 'mele le likarolo tsa mokelikeli li ntse li e-na le tšusumetso e tobileng ho tekanyo ea phallo.
Gas vortex flowmeter ke mofuta o mocha oa flowmeter o lekanyang phallo ea mokelikeli liphaepheng tse koetsoeng ho latela molao-motheo oa Karman vortex.Ka lebaka la ho ikamahanya le maemo, e khona ho lekanya ka kotloloho phallo ea mouoane, moea, khase, metsi le mokelikeli ntle le matšeliso a mocheso le khatello.E na le li-sensor tsa mocheso le khatello, e khona ho lekanya phallo ea molumo le phallo ea boima tlas'a maemo a tloaelehileng, e leng ho thothomela.Sehlahisoa se loketseng sa ho nka sebaka sa mofuta oa flowmeter.
Ka tsoelo-pele e tsoelang pele ea saense le thekenoloji, li-flowmeter tsa turbine tsa khase li sebelisoa haholo le ho feta.Ho khetha phallo ea turbine ea khase e loketseng ke ea bohlokoa haholo, joale u ka khetha joang?
Pele ho tsohle, ntho ea pele eo u lokelang ho nahana ka eona ha u khetha phallo ea turbine ea khase ke ho nepahala ha sesebelisoa.E le karolo ea ho lekanya, ho nepahala ha phallo ea turbine ea khase ke ntlha ea bohlokoa haholo.Ha ho nepahala ha phallo ea turbine ea khase, ho matlafatsa mohala oa induction ho ea tikolohong e potolohileng, le ho phahamisa litlhoko tsa tikoloho.
Taba ea bobeli, hoa hlokahala ho nahana ka mefuta e fapaneng, e bolelang sebaka sa phallo ea khase.Ha phallo ea khase e le khōlō haholo, e tla baka tšenyo ho sesebelisoa sohle.Ka hona, haeba tekanyo e fosahetseng ea phallo e khethiloe, e tla baka tšenyo ho flowmeter ea turbine ea khase.Kahoo ho khetha pakeng tsa mefuta e fapaneng le eona ke ntlha ea bohlokoa.Lintlha tse ka holimo ke lintlha tse lokelang ho hlokomeloa ha u khetha phallo ea turbine ea khase.Ha feela lintlha tsena li ntse li lateloa, u ka khetha phallo ea turbine ea khase e loketseng litlhoko tsa hau tsa mosebetsi.
Joalo ka sesebelisoa sa ho lekanya phallo e nepahetseng, se ka sebelisoa ho lekanya phallo le kakaretso ea mokelikeli ha o bapisoa le kakaretso ea phallo e tsamaellanang.Phallo ea turbine ea khase e sebelisoa haholo ho lekanya le ho laola tsamaiso ea peterole, indasteri ea lik'hemik'hale, metallurgy, lipatlisiso tsa saense le likarolo tse ling.
