Ukukalwa kwezinga lokugeleza okunembile kubalulekile ekulondolozeni amandla ngendlela efanele kanye nokulungiswa kwezimboni kanye nezitshalo zamakhemikhali. Ukukhetha indlela efanele kubaluleke kakhulu ngokuya ngohlobo loketshezi, izidingo zesistimu, ngisho nemininingwane yohlelo lokusebenza. Izimpawu zoketshezi ziyahlukahluka nge-viscosity, ukuminyana, izinga lokushisa, inani le-pH namandla okugqwala. Ngaphezu kwalokho, izimo zesistimu ezifana nokucindezela, ukugeleza kanye nendawo esetshenziswayo kufanele kubalwe ngayo.
Iyini i-Flow Rate?
Izinga lokugeleza libhekisela enanini loketshezi oluthumela ngephoyinti ngesikhathi seyunithi ngayinye. Ikalwa ngamayunithi afana namalitha ngesekhondi noma amalitha ngomzuzu ngokwejwayelekile. Kuyipharamitha ebalulekile kubunjiniyela be-hydraulic kanye nesayensi yezokwelapha. Onjiniyela bayakwazi ukuthola imininingwane mayelana nokulawulwa koketshezi, ikakhulukazi okubamba iqhaza ekuthuthukiseni ukucubungula kwezimboni nokwenza izinqumo ezinolwazi.
Izici Ezithonya Izinga Lokugeleza
Ukuqonda izinto ezithinta izinga lokugeleza kuyimfuneko yokukhetha isimo esingcono kakhulu sokulinganisa izinga lokugeleza. Uhlobo loketshezi, indawo, isimiso sokugeleza, izinga lokushisa, ingcindezi, usayizi wamapayipi, ukumiswa kanye nezimo zokufakwa kwazo zonke izici ezithonya izinga lokugeleza.
Khomba Uhlobo Loketshezi
Kubalulekile ukukhomba ukuthi iyiphi imidiya osebenza nayo. Ubuchwepheshe obukhethekile bokulinganisa ukugeleza kufanele kwamukelwe ukwehlukanisa uketshezi ngalunye. Isibonelo, amagesi angacindezelwa kodwa uketshezi alukwenzi; ukuminyana kwesitimu kuyahlukahluka. Uketshezi oluphakeme lwe-viscosity olufana nowoyela lusakazeka ngamapayipi ngendlela ehlukile kunoketshezi olune-viscosity oluphansi njengamanzi. Kudingeka ukuthi abanikazi nonjiniyela bezitshalo ezihlukahlukene bakhethe ubuchwepheshe obufanele bokulinganisa okunembile nokulawula okunembile.
Lilinganisa kanjani izinga lokugeleza?
I-Volumetric noma I-Mass Flow Meters
Ukukhetha phakathi kokulinganisa kwe-volumetric noma ukugeleza okukhulu kuyisinyathelo esibalulekile ngaphambi kokuthuthukisa ukunemba kwezinhlelo zoketshezi.Amamitha wokugeleza we-Volumetriczilungele uketshezi lokuminyana oluhlala ezingeni elizinzile, ikakhulukazi uketshezi oluningi namagesi ohlelweni lokucubungula.Isilinganiso sokugeleza okukhulukuyadingeka uma kwenzeka ukuminyana kushintsha ngokushisa nokucindezela. Ngokubuka kwalesi sizathu, amamitha okugeleza kwenqwaba asetshenziswa ukuze kuthathwe inani eliphelele lempahla edlula iphoyinti ngesikhathi seyunithi.
Khetha Imitha Yokugeleza Efanelekile
I-Volumetric Flow Meters
Ultrasonic Flow Meter
I-Magnetic Flow Meter
I-Turbine Flow Meter
I-Mass Flow Meters
Chofoza lapha futhi ubuke ulwazi olwengeziweizinhlobo zokugeleza kwamamitha.
Linganisa Inombolo ye-Reynolds (Uma Kudingeka)
Linganisa inombolo ye-Reynolds ukuze ubikezele ukugeleza okusekelwe kusivinini soketshezi, ukuminyana, i-viscosity nobubanzi bepayipi, kungaba i-laminar noma i-turbulent. Uketshezi lungase lubhekwe njenge-laminar lapho i-Reynolds inombolo ingaphansi kuka-2,000 cishe. Ngamanye amazwi, uketshezi luyanyakaza lapho ama-Reynolds ebiza ngaphezu kuka-4,000. Hlola isimiso sokugeleza ngezinombolo ze-Reynolds ukuze uthole ukubaluleka kokusebenza nokunemba kwamamitha okugeleza.
Ukufakwa Kwemitha Egelezayo
Ukufaka imitha yokugeleza esigabeni esiqondile kumagobe angenalutho, ama-valve nokunye ukuphazamiseka kuyisixazululo esingcono kakhulu sokusebenza kahle, lapho ukugeleza kwamanzi kuhlala kuqinile futhi kufana. Ngaphezu kwezici ezingenhla, ukuqondanisa kungesinye isizathu esithinta ukunemba kwamamitha ngokuphazamiseka kokugeleza okubangelwa yinoma yiluphi uhlobo lokungalungi kahle. Amaphutha okusebenza nokusebenza kungathuthukiswa kakhulu ngangokunokwenzeka uma yonke leyo mininingwane ibalwa ekufakweni.
Yenza Ukulinganisa Okudingekayo ngaphambi Kwesilinganiso Esivumelanayo
Ukulinganisa kubalulekile ukuze uqinisekise ukunemba kwemitha yakho yokugeleza, ikakhulukazi ezinhlelweni zezimboni lapho ukunemba kubaluleke kakhulu. Ukuqhuba ukulinganisa kuhlanganisa ukuqhathanisa okukhiphayo kwemitha nezinga elaziwayo nokulungiswa njengoba kudingeka ukuze kuqinisekiswe ukufundwa kungaphakathi kwamazinga okubekezelela amukelekayo. Ukulinganisa okuvamile akugcini nje ngokugcina ukunemba kwemitha kodwa futhi kwandisa ukuphila kwayo kokusebenza, ukuvimbela amaphutha abizayo noma ukungasebenzi kahle ekulawuleni inqubo.
