Ngoku, masiphonononge iintlobo ezahlukeneyo zeemitha zokuhamba.
Imitha yokuhamba-Iindidi zokuhamba
Ukuhamba kweemitha kuza kuza ngeendlela ezahlukeneyo, nganye inemigaqo eyahlukileyo yokusebenza kunye nokusetyenziswa. They can be broadly categorized into two main groups: mechanical flow meters and electronic flow meters.
A. Ukuhamba kwemitha-oomatshini bokuhambahamba
I-1. I-Reotaiters
I-Reotameters, ekwabizwa ngokuba yindawo eyahlukileyo yokuhamba, isebenza kumgaqo-siseko wento edadayo (ihlala i-piston okanye i-piston) inyuka okanye iwele kwi-tube yenqanaba lokuhamba. Isikhundla sento sibonisa umgangatho wokuhamba. Zihlala zisetyenziselwa ukulinganisa amaxabiso okuhamba okulinganisela okulinganiselweyo kwegesi kunye nolwelo.
I-2. Iimitha zokuhamba kweTurbine
Iimitha zokuhamba kwe-turbine zisebenzisa i-rount ye-spinning ebekwe kwindlela yolwelo. Isantya seRotor sihambelana nenqanaba lokuhamba, ukuvumela imilinganiselo echanekileyo. Ezi ntlobo zihlala zisetyenziswa kumashishini anjengePetroleum, iikhemikhali, kunye nolawulo lwamanzi.
I-3. Ukuhamba kwexesha lokuhamba
Ukuhamba kwe-subcentety gests ekuhambeni kwexesha kunciphisa ivolumu ye-fluid ngokufaka okanye ukubala imiqulu yeGuqulelo. Zichanekile kakhulu kwaye zilungele ukulinganisa amanqanaba okuhamba kwamanqanaba aphantsi koomasipala be-viscous kunye nolwelo olungelulo lwe-vicous.
I-4. Iimitha ezahlukeneyo zokuhamba
Iimitha ezahlukeneyo zokuhamba koxinzelelo, kubandakanya iiplate ze-orifice kunye neetyhubhu zeVenturi, sebenza ngokwenza uxinzelelo lwehla ngendlela eqhubekayo kwindlela yokuhamba. Umahluko woxinzelelo usetyenziselwa ukubala inqanaba lokuhamba. Ezi mitha zisetyenzisiwe.
B. Imitha yokuhamba-i-elektroniki ukuhamba
I-1. Iimitha zokuhamba kwe-elektromagnetic
Iimitha zokuhamba kwe-electromagnetic zisebenza kwiMigaqo yomthetho we-elektroniki ye-elektromagnetic. Zilungele ukulinganisa ukuhamba kolwelo oluzinzileyo kwaye zihlala zisetyenziswa kunyango lwamanzi, ulawulo lwamanzi amdaka, kunye nokuqhubekiswa kwamachiza.
I-2. Iimitha zokuhamba kwe-ultrasonic
Iimitha zokuhamba kwe-ultrasonic zisebenzisa amaza e-ultrasonic ukulinganisa amaxabiso okuhamba. Abangengabinamntu kwaye banokulinganisa uluhlu olubanzi lwee-fluids, kubandakanya ulwelo kunye neegesi. Ezi mitha zixabisekileyo kumashishini anjenge-HVAC, amandla kunye nezinto ezisetyenziswayo zamanzi.

I-Corolis Ukuhamba kweemitha zixhomekeke kwisiphumo seCoriolis, ebangela ityhubhu etyibilikayo ukujija kwixabiso lereyithi ye-fluid. Oku kujijelwa kusetyenziswa ukulinganisa ireyithi yokuhamba ngokuchanekileyo. Zilungele ukulinganisa ukuhamba kolwelo zombini ulwelo kunye neegesi kumashishini ahlukeneyo, kubandakanya amayeza kunye nepetrochemicals.
I-4. I-vrtox yokutshintsha ukuhamba kweemitha
I-vortex yokutshintsha kweemitha zokuhamba kwe-vortex ilinganise ihamba ngokubona i-vortices esekwe downkhansem yomzimba obekwe kumjelo wokuhamba. Zisetyenziswa kwizicelo apho ukuthembeka kunye nolondolozo olusezantsi lubalulekile, njengemilinganiselo yokuhamba kwe-Steam kwizityalo zamandla.
Imitha yokuhamba-imigaqo-siseko yokusebenza
Ukuqonda imigaqo-siseko yokusebenza kubalulekile ukukhetha iImitha yokuhamba ngqo yesicelo esithile. Masiphonononge ngokufutshane imigaqo-nkqubo yokusebenza yazo zombini iimitha ze-elektroniki.
A. Ukuhamba kwemitha-umatshini wokuhamba kwamatshini wokusebenza
Ukuhamba kweemitha zomsebenzi kusebenza ngokusekwe kwiipropathi zomzimba ezinjengokuhamba kwenqaku (i-rotor, i-float, okanye ipiston), ukufuduswa kwe-fluid. Ezi mitha zibonelela ngokufunda ngokuthe ngqo ngokusekwe kolu tshintsho lomzimba, kubenza balungele izicelo ezahlukeneyo.
B. Imitha yokuhamba-ukuhamba nge-elektroniki
Iimitha ezihamba nge-elektroniki, kwelinye icala, zisebenzisa itekhnoloji yale mihla ifana nemimandla ye-electromagnetic, amaza e-Ultrasonic, amaZiko eCoriossis, okanye i-qurtex yamanzi ukulinganisa amaxabiso okuhamba. Ezi mitha zibonelela ngedatha yedijithali kwaye zihlala zichanekile kwaye ziguquguqukayo kunabalingane labo. Ukusebenza kwabo kubandakanya oosoyena kunye ne-elektroniki eziguqula imilinganiselo yomzimba ibe yimfundo yedijithali.
Iindlela zokuhamba-Ukukhetha iikhrayitheriya
I-1. Iipropathi ze-fluid:Ukukhetha imiqolo yokuhamba kuyahambelana nepropathi ye-fluid ilinganiswe. Izinto ezifana noVelosity, ukuxinana, kunye nokuhambelana nemichiza kudlale indima ebalulekileyo. Iinditha ezahlukeneyo zokuhamba zilungele ukuba zingcono kulwelo ngeepropathi ezahlukeneyo.
2. Uluhlu lwexabiso lokuhamba:Ukuchonga inqanaba lokuhamba kwereyitha kulubalulekile. Iimitha zokuhamba zenzelwe amaxabiso athile okuvala, kwaye ukhetha enye ehambelana noluhlu lwakho lwesicelo ibalulekile ukuqinisekisa imilinganiselo echanekileyo.
I-3. Iimfuneko zokuchaneka:Ukuchaneka kweyona nto iphambili kumashishini amaninzi. Cinga ngenqanaba elifunekayo lokuchaneka kwaye ukhethe imitha yokuhamba edibana nayo loo migangatho. Ezinye izicelo zifuna ukuchaneka okuphezulu, ngelixa ezinye zivumela ukuchaneka okuncinci.
4. Ukuqwalaselwa kofakelo:Indawo yokufakelwa inokwenza ifuthe intsebenzo yemitha. Izinto ezinje ngobukhulu be-pipe, ukuqhelaniswa nezifundo, kunye nokufikeleleka kufuneka ziqwalaselwe ukuqinisekisa ukufakelwa ngokufanelekileyo.
I-5. Iindleko kunye nolondolozo:Ixabiso le-ndleko yinto nakweyiphi na iprojekthi. Ukuvavanya zombini iindleko zokuqala zemitha yokuhamba kunye neendleko zokulungisa okuqhubekayo zibalulekile. Ezinye iimitha zifuna ukulingana kunye nokulungiswa, ngelixa ezinye zilungiswa kancinci.
Ukuqukumbela
Imitha yokuhambaNgaba izixhobo ezinokuzibandakanya ezifumana izicelo kuwo onke amashishini, ukuqinisekisa ukulinganisa ngokuchanekileyo kunye nolawulo lwamaxabiso okuhamba kwamanzi. Ukukhetha phakathi kweemitha ze-elektroniki kunye neemitha ze-elektroniki kuxhomekeke kwizinto ezinje ngohlobo lolwelo, inqanaba lokuhamba, kunye nenqanaba lokuchaneka elifunekayo. Ukuqonda imigaqo-siseko yokusebenza kunye neentlobo ngeentlobo zeemitha ezikhoyo zibalulekile ekwenzeni izigqibo ezinolwazi xa ukhetha isixhobo esifanelekileyo kwaso nasiphi na isicelo esithile.
Umvelisi weemitha zemitha: i-shanghai ye-shanghai ye-COCE COCE. Ukuzinikela kwabo kubuyi nangobuhlobo lwabo kubenza babe ligama elithenjiweyo kwicandelo lemilinganiselo yokuhamba.
