Ukukala Ukugeleza Kwegesi Yemvelo

Amabhizinisi abhekana nezinselele ezinzima ekulawuleni inqubo, ukuthuthukiswa kokusebenza kahle kanye nokuphathwa kwezindleko ngaphandle kwamarekhodi anembile okugeleza kwegesi, ikakhulukazi ezimbonini lapho igesi isetshenziswa futhi icutshungulwa ngezinga elikhulu ngaphansi kwezimo ezihlukahlukene. Njengoba ukulinganisa okunembile kwegesi yemvelo kubalulekile ekuthuthukiseni ukusebenza kahle, ukuphepha kokusebenza ngisho nokuhambisana nokulawula, ukukhetha imitha yokugeleza efanele yegesi yemvelo kuye kwaphendukela esinqumweni samasu, esidala imiphumela efinyelela kude ekukhiqizeni, ukuhambisana nemvelo kanye nokusebenza kahle kwezindleko.

Kungani Ukukala Ukugeleza Kwegesi Kubalulekile Embonini?

Ngaphezu kwezizathu ezingenhla, ukukala ukugeleza okunembile kokugeleza kwegesi kushiya wonke umsebenzi ulungile, ukuze kuqashelwe kalula ukuvuza okungenzeka nokusetshenziswa ngokweqile. Ukubonisa umbiko onemininingwane obandakanya ukusetshenziswa kwegesi kanye nezindaba ezikhishwayo ezimbonini eziningi, lapho ukukalwa okunembile kusiza futhi ukuhambisana nezindinganiso zokulawula ezibhekisele ezidingweni zemvelo nezokuphepha.

Ngaphezu kwalokho, ukushintshashintsha okunobudlova kokugeleza kwegesi kubonisa ukuvinjelwa, ukuvuza noma ukunakekelwa okukhethekile kufanele kwenziwe ukuze kuqedwe izingozi ezingaba khona. Bese uthatha izinyathelo zokuxazulula lezo zinkinga uma kunesidingo.

Amapharamitha Abalulekile Amamitha Okugeleza Kwegesi

Ziningi izici okufanele zicatshangelwe ngaphambi kokukhetha imitha yokugeleza kwegesi efanele, okuhlanganisa kodwa kungagcini nje:

✤Uhlobo lwegesi

✤Ulwazi lokugeleza

✤Izimo zemvelo

✤Indawo yokusebenza

✤ingcindezi nezinga lokushisa

✤okuhlosiwe okulindelekile

✤ukufakwa nokulungiswa

Ngaphandle kwamaphuzu okukhulunywe ngawo ngenhla, izimfuneko zokunemba zifanelwe ukunakwa kwakho ngamaphutha ahlukahlukene amukelekayo. Ukubekezelela iphutha elincane kuyadingeka ezimbonini ezikhethekile ezifana nokusabela kwamakhemikhali nokukhiqizwa kwemithi. Ukucindezela namazinga okushisa kuyimingcele ekukhetheni amamitha okugeleza alungile, futhi. Amamitha kufanele amelane nezimo ezimbi kakhulu ngaphandle kokusebenza okwehlisa isithunzi ezinhlelweni zokucindezela okukhulu. Kusho ukuthi ukugcina ukuthembeka kwamamitha okugeleza ezimweni ezinjalo kubalulekile ekusebenzeni kwesistimu okuhlala isikhathi eside.

Izinselelo Ekukaleni Ukugeleza Kwegesi

Igesi yemvelo, njengomthombo wamandla ahlanzekile, iya ngokuya isetshenziswa, futhi ingxenye yayo esakhiweni samandla ikhuphuka minyaka yonke. Ngokuthuthukiswa kweProjekthi Yepayipi Legesi YaseNtshonalanga-Mpumalanga e-China, ukumbozwa kwegesi yemvelo kuyakhula, okwenza isilinganiso sokugeleza kwegesi yemvelo kube isinyathelo esibalulekile.

Njengamanje, ukukalwa kokugeleza kwegesi yemvelo kusetshenziswa ngokuyinhloko ezindaweni zokuhwebelana, futhi ukulinganisa e-China kuncike kakhulu kumitha yevolumu. Igesi yemvelo ihlinzekwa ngezindlela ezimbili ngokujwayelekile: igesi yemvelo yamapayipi (PNG) kanye negesi yemvelo ecindezelwe (CNG).

Amanye amamitha akhiqizwa ngaphakathi kwezidingo ezithile, njengokudluleleivolumu ephansi futhi ephezulu. I-flow meter evumela amazinga okugeleza avamile kanye nenani eliphakeme liqinisekisa ukufundwa okuhlala njalo nokunembile. Usayizi omncane noma omkhulu ungenye into efanele ukucatshangelwa ngokukhethekile ukufaneleka kwayo yonke ingxenye yemitha yokugeleza.

Isimiso Sokusebenza

Imitha yokugeleza kwegesi yemvelo isebenza ngokulinganisa inani legesi elithunyelwa ngepayipi. Ngokuvamile, izinga lokugeleza liwumsebenzi wesivinini segesi kanye nendawo ye-cross-sectional yepayipi. Isibalo sisebenza ngama-algorithms ayinkimbinkimbi, lapho izakhiwo eziguquguqukayo zegesi yemvelo zazihlukahluka ngezinga lokushisa, ukucindezela nokwakheka koketshezi.

Izicelo zamamitha okugeleza kwegesi

Izinzuzo Nezingozi Zezinhlobo Zemitha Yokugeleza Kwegesi

Impela, abukho ubuchwepheshe obubodwa noma imitha engahlangabezana nazo zonke izidingo nemibandela yobungcweti. Ubuchwepheshe obune obujwayelekile bokulinganisa ukugeleza kwegesi busetshenziswa ekucubunguleni izimboni namuhla, bunamandla ahambisanayo kanye nemikhawulo. Kungenzeka ukuvimbela amaphutha abizayo ngemva kokuqonda izinzuzo zawo kanye nokubi.

No.1 Electromagnetic Flow Meters

I-electromagnetic flow meter isebenza kumgomo woMthetho kaFaraday wokungeniswa. Ikhoyili kagesi ngaphakathi kwemitha yokugeleza kwe-mag ikhiqiza insimu kazibuthe bese ama-electrode ekwazi ukubona i-voltage. Inkambu kazibuthe ishintsha ngamandla anjalo lapho uketshezi ludlula epayipini. Ekugcineni, izinguquko ezinjalo zizohunyushwa kuzinga lokugeleza.

Ukukhetha imitha yokugeleza kwegesi efanele kuhlanganisa ukunemba kokulinganisa, ukuqina, kanye nezindleko ukuze zivumelane nezidingo ezithile zohlelo lokusebenza. Ukukhetha okunolwazi akugcini nje ngokuthuthukisa ukusebenza kahle kodwa futhi kusekela ukuthobela imithetho nokuphepha. Ngokuqonda izinhlobo zamamitha ahlukahlukene nokufaneleka kwazo ezimweni ezihlukene, izimboni zingafinyelela ukusebenza kahle, zinciphise izindleko, futhi ziqinisekise ukwethembeka kwamasistimu azo. Ukwenza ukukhetha okufanele ekugcineni kuholela ekusebenzeni okuqinile, okuqinile okungahlangabezana nezimfuneko zamanje nezinselele zesikhathi esizayo.
