Umehluko phakathi kokugeleza kweMisa nokugeleza kweVolumetric

Ukulinganisa ukugeleza koketshezi ezindabeni ezinembile ezinhlelweni ezihlukahlukene zobunjiniyela nezimboni, okuqinisekisa ukusebenza kahle nokusebenza kahle. Kunezinzuzo ezisobala ngokulinganisa ukugeleza kwenqwaba kunokugeleza kwevolumu, ikakhulukazi emoyeni ocindezelwe kanye namagesi obuchwepheshe afana ne-argon, i-co2 ne-nitrogen. Funda indatshana futhi uthole ukuqonda kochwepheshe kukho kokubili ukulinganisa.

Kuyini ukugeleza kwenqwaba?

Ukugeleza okukhulu kubhekisela esikalini sokudlula kwenqwaba ngesikhathi seyunithi. IMisa imelela inani eliphelele lama-molecule ahamba emikhumbini ethile, angathinteki ekushintsheni kwezinga lokushisa nokucindezela. Ngokuhlukile ngevolumu, isisindo segesi sihlala singashintshi naphezu kokushintshashintsha kwezimo zemvelo. Izinga lokugeleza kwesisindo lichazwa ngamayunithi afana namakhilogremu ngehora (kg/hr) noma amaphawundi ngomzuzu (lb/min); amagesi achazwa ngama-cubic metres ajwayelekile ngehora (Nm³/hr) noma ama-cubic ft ajwayelekile ngomzuzu (SCFM).

Iyini i-Volumetric Flow?

Ukugeleza kwevolumu kusho ukugeleza kwangempela, ukulinganisa ivolumu ehambayo ngesikhathi seyunithi. m3/hr, m3/min, CFM noma ACFM amayunithi avamile wokugeleza kwevolumu, asetshenziswa ukuchaza ukuthi inkulu kangakanani endaweni enezinhlangothi ezintathu. Umthamo wamagesi ulingana ngokuqondile nezinga lokushisa nokucindezela. Umthamo wegesi uyanda ngokukhuphuka kwezinga lokushisa nokucindezela; kunalokho, incipha ngokuncipha kwezinga lokushisa nokucindezela. Ngamanye amazwi, izinga lokushisa nokucindezela kufanele kucatshangelwe lapho kulinganiswa ukugeleza kwevolumu.

Isilinganiso sokugeleza okukhulu vs isilinganiso sokugeleza kwevolumu

Ulwazi oluningiliziwe lwezinga lokugeleza kwesisindo kanye nezinga lokugeleza kwe-volumetric kunenzuzo ukukhetha indlela yokulinganisa efanele. Izinga lokugeleza okukhulu linembile kakhulu futhi linokwethenjelwa ezinqubweni, lapho ukuminyana koketshezi kungase kushintshe khona kanye nezinga lokushisa nokucindezela. Lobu buchwepheshe budumile ezimbonini ezinamathisela ukubaluleka okukhulu ekulawuleni ukunemba phezu kwezakhiwo eziwuketshezi, njengemithi namakhemikhali e-petrochemical.

Ngokuphambene nalokho, isilinganiso sokugeleza kwe-volumetric sinamandla ngokwanele ezimbonini lapho ukunemba kungabalulekile kangako. Isibonelo, indlela inokwethenjelwa ngokwanele ekuqapheni nasekulawuleni ukugeleza ohlelweni lokunisela lwezolimo kanye namanethiwekhi okusabalalisa amanzi, ingasaphathwa izinxephezelo eziyinkimbinkimbi ezidingekayo ekucutshungulweni. I-Volumetric iyindlela elula futhi engabizi kakhulu ezimbonini ezithile. Ukunemba kungenzeka uma izimo zemvelo zingaphathwa ngendlela efanele.

Izinzuzo Zokulinganiswa Kokugeleza Okuningi

Inzuzo eyinhloko yokusebenzisa isilinganiso sokugeleza kwenqwaba incike ekunembeni nasekuthembekeni kwayo, ukunciphisa ukuncika ekulungisweni kwezinga lokushisa nokucindezela. Ukuhlobana okuqondile phakathi kokugeleza kwenqwaba kanye nezakhiwo zoketshezi kuvumela ukuqapha kwesikhathi sangempela ngaphandle kobunzima bezibalo eziyisinxephezelo.

Khetha isilinganiso sokugeleza okukhulu ukuze uthole ukulawula okunembe kakhudlwana kokucubungula. Izinqumo ezinolwazi zingenziwa abaqhubi abanedethi yokugeleza enembayo abanayo ukuze banciphise udoti futhi bathuthukise ikhwalithi yomkhiqizo. Ukuqapha njalo kwamazinga okugeleza okukhulu kuvumela opharetha ukuthi balungise ngokuvumelana nezimo ezishintshayo, okushiya ukusebenza kwakho kuhlale kusebenza kahle futhi kusebenza kahle.

Nini ukusebenzisa imitha yokugeleza kwe-volumetric noma imitha yokugeleza kwenqwaba?

Amamitha okugeleza kwevolumu ayanconywa ezinhlelweni ezinamathisela ukubaluleka okuncane ekunembeni okuphezulu. Noma kunjalo, imitha yevolumu idinga isinxephezelo esengeziwe kusuka ekushiseni okungeziwe nokucindezela. Nakuba ulwazi olwengeziwe ngezinga lokushisa nokucindezela alukwazanga ukubeka usongo ekunembeni okuphezulu nokuphindaphinda. Ngakho-ke, amamitha okugeleza kwenqwaba athembekile futhi anembe kakhulu uma eqhathaniswa namamitha okugeleza kwe-volumetric.

Nini ukusebenzisa imitha yokugeleza kwe-volumetric noma imitha yokugeleza kwenqwaba?

Izinzuzo zamamitha okugeleza kwenqwaba ziphoqa abantu abajwayele amamitha okugeleza kwe-volumetric ukuthi benze izinguquko ezithile ekucubunguleni okukhethekile kwemboni. Ngenhlanhla, kulula ukunikeza ukugeleza kwevolumu ngemitha yokugeleza kwenqwaba, ukufinyelela umgomo ngokungeza ivolumu (okubizwa nangokuthi ububanzi bepayipi) kumitha yokugeleza.

Indlela yokuguqula ukugeleza kwe-mass ku-volumetric flow?

Mhlawumbe kuyadingeka ngezinye izikhathi ukuguqula ukugeleza kwenqwaba kube ukugeleza kwe-volumetric. Ukuguqulwa kufinyelelwa ngemva kokusebenzisa ifomula eqondile, kusetshenziswa amanani afanele wokuminyana kusibalo esilandelayo.

I-Volumetric Flow Rate=Izinga Lokugeleza Okukhulu/Ukuminyana

Ukuminyana kuhlotshaniswa nesilinganiso sokugeleza kwenqwaba nezinga lokugeleza kwevolumu. Futhi ukuminyana kuhambisana ngokuphambene nezinga lokushisa nokucindezela. Okungukuthi, amazinga okushisa aphezulu abangela ukuminyana okuphansi kanye nezingcindezi eziphezulu ezibangela ukuminyana okuphansi, futhi. Iizinga lokugeleza kwe-volumetricitholakala ngokuhlukanisa iisilinganiso sokugeleza okukhulunge-fluid density. Aizinga lokugeleza kwe-volumetricziyahlukahluka ngezinga lokushisa kanye nomfutho, kuyilapho aisilinganiso sokugeleza okukhuluihlala njalo lapho izinga lokushisa noma ukucindezela kushintsha.

Amasistimu okulinganisa ukugeleza ahlanganisiwe anezixazululo ezizenzakalelayo athuthukisa ukusebenza kahle kanye nekhwalithi yemikhiqizo yokugcina kakhulu. Ngaphezu kwalokho, ukulungisa kahle amazinga okugeleza kanye nokuhlaziya kwesikhathi sangempela kwenza iminikelo ekusebenzeni kahle ngaphandle kokuphazamiseka kwenqubo. Indlela ye-proactive ithatha imithelela kukho kokubili ukusebenza okulula kanye nokuthuthukiswa okuqhubekayo.

Kafushane, ukuqonda ama-nuances wokugeleza kwenqwaba kanye nezilinganiso zokugeleza kwe-volumetric kubalulekile ekuthuthukiseni ukusebenza ezinhlelweni ezihlukahlukene. Ngokusebenzisa izindlela zokulinganisa ezifanele kanye nokwamukela amandla endlela ngayinye, ochwepheshe bangathuthukisa ukusebenza kwabo futhi bathole ukunemba okukhulu ezinqubweni zabo zokulawula uketshezi.
