Izinzuzo ze-Coriolis mass flowmeters

Ama-flowmeter e-Coriolis mass, alinganisa ngqo ukugeleza kwesisindo soketshezi ngokusekelwe kumphumela we-Coriolis, ayizinto ezinembile kakhulu ezinezinzuzo ezilandelayo eziyinhloko:

1. Ukulinganisa ukugeleza kwesisindo okuqondile ngaphandle kwesinxephezelo

• Zikhipha ngqo ukugeleza kwesisindo (amayunithi: kg/h, t/h, njll.) futhi azithinteki yizinguquko kumapharamitha oketshezi njengokushisa, ingcindezi, ubuningi, kanye ne-viscosity. Azikho ezinye izisetshenziswa zokunciphisa izinga lokushisa/ingcindezi ezidingekayo, okuqinisekisa ukunemba kokulinganisa okuzinzile.
• Uma kuqhathaniswa nama-flowmeter e-volumetric (isb., ukuchitheka kwe-vortex, ama-orifice plate), agwema amaphutha okulinganisa abangelwa izinguquko esimweni soketshezi, okwenza afaneleke kakhulu kuma-fluid axubile anezingxenye eziningi noma ama-fluid okushintsha kwesigaba (njengoketshezi oluqukethe amabhamuza).

2. Ukunemba okuphezulu kokulinganisa kanye nokuphindaphinda okuhle kakhulu

• Imikhiqizo yezinga lezimboni ivame ukufeza ukunemba kokulinganisa okungu-±0.1% kuya ku-±0.5% kokufundwa, futhi amamodeli anokunemba okuphezulu angafinyelela ngisho ku-±0.05%, edlula kakhulu ezinye izinhlobo eziningi zama-flowmeter.
• Zinikeza ukuphindaphindeka okuhle kakhulu (ngokuvamile okungu-≤±0.05%) kanye nokuzinza okuqinile kokusebenza kwesikhathi eside, okwenza zifaneleke ezimweni ezinezidingo eziphezulu zokuthembeka kwedatha, njengokuxazulula ukuhweba kanye nokulawula inqubo yokunemba.

3. Uhla olubanzi lweziketshezi ezisebenzayo

• Bangakwazi ukukala cishe zonke izinhlobo zoketshezi:
  • Uketshezi (kufaka phakathi uketshezi olunamandla aphezulu, ama-slurry aqukethe izinhlayiya, uketshezi oluqothulayo, njll.);
  • Amagesi (kufaka phakathi amagesi anomfutho ophezulu, amagesi amanzi, amagesi axubile anezingxenye eziningi);
  • Ukugeleza kwegesi-uketshezi kwezigaba ezimbili (ukugcina ukunemba ngaphakathi kobubanzi obuthile besilinganiso).

4. Umklamo wendlela yokugeleza engavinjelwe

• Azikho izinto ezicindezelayo, ama-turbine, noma ezinye izingxenye ezihambayo ngaphakathi kwenzwa. Ukulinganiswa kufezwa kuphela ngokudlidliza kwephayiphi uqobo. Ngakho-ke:
  • Ukulahlekelwa yingcindezi kuncane, okuholela ekusetshenzisweni kwamandla okuphansi;
  • Azivami ukuvaleka, okunciphisa izindleko zokulungisa, ikakhulukazi ezifanele uketshezi oluqukethe ukungcola noma ukujiya okuphezulu;
  • Zinesikhathi eside sokusebenza, zinciphisa ukonakala kokunemba okubangelwa ukuguguleka kwezingxenye.

5. Amandla okukala amapharamitha amaningi ngasikhathi sinye

• Ngaphezu kokugeleza kobuningi, amamodeli amaningi angakhipha amapharamitha afana nokuxinana koketshezi kanye nokushisa, afinyelele "imitha elilodwa lokusetshenziswa okuningi". Lokhu kwenza kube lula ukwakheka kohlelo futhi kunciphisa izindleko zemishini.
• Ukunemba kokulinganisa ubuningi kungafinyelela ku-±0.001 g/cm³, okungasetshenziswa ukuqapha ukuhlushwa koketshezi (isb., okuqukethwe okuqinile kusiraphu noma odakeni).

6. Ukufakwa nokugcinwa okulula

• Zinezidingo eziphansi zezingxenye zamapayipi aqondile, okususa isidingo sokuqhutshwa kwamapayipi aqondile aqondile angenhla nangezansi, okwenza kube lula ukwakheka kokufakwa endaweni.
• Njengoba kungekho izingxenye ezihambayo, izinga lokwehluleka liphansi, kunciphisa imvamisa yokugcinwa nokufakwa kwemishini, futhi kunciphisa izindleko eziphelele zobunikazi.
