Ukuhlaziywa kwe-Pressure-Volume-Temperature (PVT)Kubalulekile ekuqondeni ukuthi uketshezi lwamachibi luziphatha kanjani ngaphansi kwezimo ezahlukahlukene embonini kawoyela. Lokhu kuhlaziya kwazisa izinqumo ezibalulekile mayelana nokuphathwa kwamachibi, amasu okukhiqiza, kanye nokwenza ngcono ukubuyisa.
Okubalulekile kuya ekusebenzeni kahleUkuhlaziywa kwe-PVTizilinganiso eziqondile zeukuminyana koketshezikanye ne-viscosity, okwembula ukwakheka kanye nezici zokugeleza kwe-uketshezi olugciniweIzindlela zendabuko ezisekelwe elabhorethri zivame ukuhilela ukubambezeleka kanye nokungalungi okungenzeka ngenxa yokuphathwa kwamasampula.
Isixazululo Esihlanganisiwe sikaLonnmeter Sezifundo ze-PVT
Njengomhlinzeki ohamba phambili wezixazululo zokulawula inqubo ezihambisanayo, iLonnmeter inikeza ikhambi elishintsha umdlalo ngesisombululo sayoamamitha obuningi obungaphakathifuthiamamitha e-viscosityLawa mathuluzi athuthukile ahlinzeka ngedatha yesikhathi sangempela nenembile yeUkuhlaziywa kwe-PVT koketshezi lwedamu, okwenza onjiniyela bakwazi ukwenza izinqumo ezinolwazi ngokushesha nangendlela ephumelelayo. Njengoba yakhelwe izimo ezidingakalayo zama-oyili, amamitha angaphakathi noma izinzwa zenqubo ezingaphakathi noma ezingaphakathi ziqinile, kulula ukuzisebenzisa, futhi zithembeke kakhulu, okwenza zilungele ukusetshenziswa.ukuhlaziywa kwe-PVT kawoyela.
Amamitha e-inline density kanye ne-viscosity kaLonnmeter akha ikhambi elinamandla elihlanganisiwe le-Ukuhlaziywa kwe-PVT kwama-reservoirs kawoyela. IImitha yobuningi be-LONN700kwenza kube lulaukuminyana koketsheziukulinganisa ngaphakathi komfudlana wenqubo, kuyilapho amamitha e-viscosity enikeza idatha ye-viscosity yesikhathi sangempela. Ndawonye, la mathuluzi aletha ukuhlukaniswa okuphelele koketshezi, okubalulekile ekuqondeniuketshezi lwethangiukuziphatha. Ngokuhlanganisa amamitha angenhla, onjiniyela bangaqapha izakhiwo ezibalulekile ngaphandle kwesidingo sokuthatha amasampula ngesandla, banciphise amaphutha abangelwa ukusebenza ngesandla okuphindaphindiwe. Kunciphisa isikhathi esiningi kanye nokuthatha amasampula ngesandla okunzima futhi kuthuthukise ukusebenza kahle.
Ukuqina kanye nobuchwepheshe bezinzwa obuphakeme
Amamitha eLonnmeter akhiwe ukuze amelane nezimo ezinzima zokusetshenziswa kukawoyela negesi.imitha yobuningi boketshezi emugqeniyakhiwe ngezinto eziqinile njengensimbi engagqwali, i-Hastelloy, noma i-Titanium, okuqinisekisa ukuhambisana nokugqwalauketshezi olugciniweIsebenza ngokucindezela okufika ku-1 MPa kanye nokushisa okumanzi okusukela ku--10°C kuya ku-120°C, kanye nokushisa okuzungezile okusukela ku--40°C kuya ku-85°C. Imitha ye-viscosity iqine kakhulu, iphatha ukucindezela okufika ku-10 MPa (okungenziwa ngokwezifiso) kanye nokushisa okufika ku-450°C. Zombili lezi zinsimbi zihlangabezana nezindinganiso eziphakeme zokuvikela imvelo (IP67/IP68) kanye nezilinganiso zokuvikela ukuqhuma (ExdIIBT4 ye-viscosity, ExdIIBT6 ye-density), okuqinisekisa ukuphepha ezindaweni eziyingozi. Lobu buchwepheshe bezinzwa obuphezulu buqinisekisa ukuthembeka kwesikhathi eside, kunciphisa isikhathi sokungasebenzi kuukuhlaziywa kwe-PVT kawoyela.

Izinzuzo Zokulinganisa Ubuningi Nokugoba Okuhlanganisiwe
Ukuhlanganiswa kokulinganiswa kobuningi kanye ne-viscosity kuyitshe elibalulekile ekusebenzeni kahleUkuhlaziywa kwe-PVT kwama-reservoirs kawoyela. Ubuningi boketsheziinikeza ukuqonda ngokwakheka kanye nokuziphatha kwesigabauketshezi olugciniwe, kuyilapho i-viscosity inquma izici zokugeleza ezibalulekile ekubikezelweni komkhiqizo. Ngokusebenzisa amamitha angaphakathi e-Lonnmeter, onjiniyela bangathola izilinganiso zombili ngasikhathi sinye, okuvumela ukumodela okuphelele koketshezi. Idatha yesikhathi sangempela ivumela ukulungiswa okusheshayo, ukuthuthukisa ukulawulwa kwenqubo kanye nokunciphisa ingozi yezinkinga zokukhiqiza. Le ndlela ehlanganisiwe ithuthukisa ukunemba kokulingisa kwamachibi, yenza ngcono amasu okukhipha, futhi isekela imisebenzi engabizi kakhulu, okwenza kube yinto ebalulekileukuhlaziywa kwe-PVT kawoyela.
Ukunemba, Isivinini, Nokuthembeka
Amamitha e-Lonnmeter anikeza ukusebenza okuhle kakhulu maqondana nokunemba, isivinini, kanye nokuthembeka. Imitha yobuningi be-LONN700 ifinyelela ukunemba okungu-±0.002 g/cm³ (±0.25%) kanye nokuphindaphinda okungu-±0.0001 g/cm³ (±0.1%), ngesikhathi sokuphendula samasekhondi ama-2 kuphela. Imitha yokulinganisa inikeza ukunemba okungu-±3.0% kanye nokuphindaphinda okungu-±1%, ngesikhathi sokuphendula samasekhondi ama-5. Lezi zikhathi zokuphendula okusheshayo ziqinisekisa idatha ecishe ifane ngokushesha yokulawula inqubo enamandla. Umklamo ongenazo izilungiso, ongenazo izingxenye ezihambayo, uthuthukisa ukuthembeka, unciphisa izindleko zokusebenza futhi uqinisekise ukusebenza okuqhubekayo kuUkuhlaziywa kwe-PVT koketshezi lwedamu.

Amakhono Okusebenza Abanzi
Amamitha eLonnmeter aklanyelwe ukuguquguquka, avumela izimo ezahlukahlukene kanye nezinhlobo zoketshezi.imitha yobuningi boketshezi emugqeniingakwazi ukuphatha uketshezi olune-viscosities kufika ku-2000 cP futhi ifaneleka uketshezi oluqukethe izinhlayiya eziqinile, okwenza kube kuhle kakhulu ezinkimbinkimbiuketshezi olugciniweImitha ye-viscosity isekela ububanzi be-viscosity obungu-1 kuya ku-1,000,000 cP, obuhlanganisa uketshezi oluphansi noluphezulu lwe-viscosity. Njengoba amazinga okucindezela kanye nokushisa enzelwe ukusetshenziswa kukawoyela negesi, lawa mathuluzi afaneleka kahle kokubili elebhu kanye nasensimini.Ukuhlaziywa kwe-PVTAmandla abo okusebenza ezimweni ezimbi kakhulu aqinisekisa ukusebenza okuthembekile kuzo zonke izimo ezahlukahlukene.
Isidingo Esincane Sosayizi Wesampula
Ngokungafani nezindlela zendabuko ezidinga ukukhipha nokuhlaziya amasampula oketshezi, amamitha angaphakathi e-Lonnmeter alinganisaukuminyana koketshezikanye nokuthambekela okubonakalayo ngqo ngaphakathi komfudlana wenqubo. Lokhu kuqeda isidingo sokuthatha amasampula ahlukene, kunciphisa ubungozi bamaphutha noma ukungcola kanye nokunciphisa ukuphathwa kwamasampula.Ukuhlaziywa kwe-PVT, lapho ukutholakala kwesampula kungase kulinganiselwe, lesi sici sinenzuzo enkulu, siqinisekisa ukulinganiswa okunembile ngaphandle kokuphazamisa inqubo.
Ukulula Nokusebenza Kalula
Amamitha angaphakathi e-Lonnmeter aklanyelwe ukusebenziseka kalula. Womabili amamitha okuqina kanye ne-viscosity “axhumeka futhi adlale,” okuvumela ukufakwa okusheshayo ngaphandle kokusetha okuyinkimbinkimbi. Ahlanganiswa kalula nezinhlelo zokulawula izinqubo ngamasignali angu-4-20mA noma e-RS485, ahlinzeka ngedatha yesikhathi sangempela yokwenza izinqumo ngokushesha. Umklamo ongenakulungiswa unciphisa izindleko zokusebenza kanye nesikhathi sokungasebenzi, okwenza la mathuluzi abe ukukhetha okusebenzayoukuhlaziywa kwe-PVT kawoyelaUkusebenziseka kalula kwazo kuqinisekisa ukuthi onjiniyela bangagxila ekuhlaziyeni kunokuphathwa kwemishini.
Ukuqhathanisa Nezinye Izobuchwepheshe
Amamitha kaLonnmeter anikeza izinzuzo ezihlukile kunobuchwepheshe obuhlukile. Ngokukalwa kobuningi, amamitha kaCoriolis ayindlela evamile, enikeza ukunemba okuphezulu kodwa ngezindleko eziphakeme futhi enobunzima obengeziwe ngenxa yomsebenzi wawo ophindwe kabili wokulinganisa ukugeleza kobuningi.imitha yobuningi befoloko yokulungisaingabizi kakhulu kuzinhlelo zokusebenza ezigxile kuphela ekuxineni. Ngokuphathelene ne-viscosity, ama-viscometer ajikelezayo awafaneleki kangako ukusetshenziswa ngaphakathi komugqa ngenxa yobunzima bawo bemishini nezidingo zokulungisa. I-viscometer edlidlizayo ye-Lonnmeter, ngokuphambene, ilungiselelwe ukulinganisa okuqhubekayo, ngaphakathi komugqa, inikeza ubulula nokuqina. Amandla okuthola kokubili amamitha okuqina kanye ne-viscosity avela ku-Lonnmeter aqinisekisa ukuhambisana nokuhlanganiswa okulula, inzuzo ebalulekile yeUkuhlaziywa kwe-PVT kwama-reservoirs kawoyela.
