Imitha yokugelezaIzinsimbi ezibalulekile zisetshenziswa ezimbonini ezahlukahlukene ukukala izinga lokugeleza koketshezi noma amagesi. Badlala indima ebalulekile ekuqapheleni nasekulawuleni ukunyakaza kwamanzi, okubalulekile ukuze basebenzise izicelo eziningi. Kule bhulogi, sizokwelulela ezweni lamamitha okugeleza, sihlola incazelo yalo, injongo, kanye nokubaluleka kwazo zonke izimboni ezahlukahlukene.
Imitha yokugeleza - Ukuchazwa nenhloso
Imitha yokugeleza, njengoba igama libonisa, yithuluzi elakhelwe ukukala izinga lapho uketshezi lugeleza khona ngepayipi noma umsele. Inikeza imininingwane ebalulekile mayelana nenani lamanzi adlula endaweni ethile ohlelweni. Le datha ibalulekile ngezinhloso eziningi, njengamakhasimende okukhokha ngokusetshenziswa kwamanzi noma igesi, ukuqinisekisa ukusebenza kahle kwezinqubo zezimboni, kanye nokubheka izimo zemvelo.
Imitha yokugeleza - Ukubaluleka Kwezimboni Ezihlukahlukene
Amamitha we-Flow amathuluzi asemqoka kubuningi bezimboni. Nazi ezinye izibonelo zokubaluleka kwazo:
1. Umkhakha kawoyela negesi:Amamitha we-Flow asetshenziselwa ukukala ukugeleza kwamafutha aluhlaza, igesi yemvelo, nemikhiqizo ehlukahlukene ecwengekile, esiza ekudluliseni kahle, ukuqapha kahle kanye nokuphathwa kwamapayipi.
2 Imboni yamakhemikhali:Izinqubo zamakhemikhali zivame ukubandakanya ukukalwa okunembile kwamanani okugeleza koketshezi ukuze kuqinisekiswe ukuxubeka okulungile kwezithako nokuvimbela izingozi zokuphepha.
3. Ukwelashwa kwamanzi:Ezitshalweni zokwelashwa kwamanzi, amamitha okugeleza asiza ekutholeni inani lokungena kwamanzi futhi aphumelele lesi sikhungo, aqinisekise ukwelashwa okusebenzayo nokusatshalaliswa.
4. Izemithi:Imboni yezemithi ithembele kumamitha okugeleza ngesilinganiso esiqondile sezithako ekukhiqizweni kwezidakamizwa.
5. Ezolimo:Amamitha okugeleza asetshenziswa ezinhlelweni zokunisela ukuphatha izinsiza zamanzi kahle.
6. Ukudla nesiphuzo:Izitshalo zokudla zokudla zisebenzisa amamitha okugeleza ukuqapha ukugeleza kwezithako, ukusiza ukugcina ikhwalithi yomkhiqizo engaguquki.
7 Umkhakha Wezamandla:Izitshalo zamandla kanye nezinsizakalo zisebenzisa amamitha okugeleza ukukala ukugeleza kwamanzi ahlukahlukene, kufaka phakathi umusi namanzi okupholisa, ukwengeza ukukhiqizwa kwamandla.
Manje, ake sihlole izinhlobo ezahlukene zamamitha wokugeleza.
Imitha yokugeleza - Izinhlobo zamamitha okugeleza
Amamitha okugeleza aza ngezinhlobo ezahlukahlukene, ngalinye linemigomo yalo eyingqayizivele yokusebenza kanye nezicelo. Zingahlukaniswa kabanzi zibe ngamaqembu amabili aphambili: Mechanical Flow Meters kanye namamitha okugeleza nge-elekthronikhi.
A. Imitha yokugeleza - Mechanical Flow Meters
1. Ama-Rotammeters
Ama-rotamters, abizwa nangokuthi njengamamitha aguqukayo wokugeleza kwamamitha, asebenza ngomgomo wento entantayo (imvamisa i-float noma ipiston) ekhuphuka noma ukuwa ngaphakathi kwe-tube ye-conical njengokushintsha kwesilinganiso sokugeleza. Isikhundla sento sibonisa isilinganiso sokugeleza. Zivame ukusetshenziselwa ukukala amazinga okuhamba aphansi anokulinganisela amagesi noketshezi.
2. Amamitha we-turbine flow
Amamitha we-turbine flow met asebenzisa i-rotor yokujikeleza ebekwe endleleni yoketshezi. Ijubane le-rotor lilingana nezinga lokugeleza, livumela izilinganiso ezinembile. Lawa mamitha ajwayele ukuqashwa ezimbonini ezinjenge-petroleum, amakhemikhali kanye nokuphathwa kwamanzi.
3. Amamitha amahle okugeleza amamitha
Amamitha amahle okugeleza kwamamitha alinganiselwe alinganisa umthamo wevolumu ngokuthwebula nokubala amavolumu e-discrete koketshezi. Zinembe kakhulu futhi zilungele ukukala amazinga okugeleza aphansi awo womabili uketshezi olungabonakali.
4. Amamitha ahlukile wokugeleza kwengcindezi
Amamitha ahlukile wokugeleza kwamamitha, kufaka phakathi amapuleti e-orifies kanye namashubhu we-ventiri, asebenza ngokwakha ingcindezi yehla ngaphesheya kwenqwaba yendlela yokugeleza. Umehluko wengcindezi usetshenziselwa ukubala isilinganiso sokugeleza. Lawa mamitha ahlukahlukene futhi asetshenziswa kabanzi.
B. Imitha yokugeleza - Amamitha okugeleza nge-elekthronikhi
1. I-Electromagnetic Flow Meters
Amamitha we-Electromagnetic Flow Maters asebenza ngomgomo womthetho weFaraday wokungeniswa kwe-electromagnetic. Zilungele ukukala ukugeleza koketshezi olusebenzayo futhi zivame ukusetshenziswa ekwelashweni kwamanzi, ukuphathwa kwamanzi amdaka, kanye nokusebenza kwamakhemikhali.
2. I-Ultrasonic Flow Meters
Amamitha we-Ultrasonic Flow Meters asebenzisa amagagasi e-ultrasonic ukukala amanani okugeleza. Azingeneki futhi zingalinganisa uhla olubanzi lwamanzi, kufaka phakathi uketshezi namagesi. Lawa mamitha abalulekile ezimbonini ezinjenge-HVAC, amandla, kanye nezinsiza zamanzi.
3. Amamitha we-coriolis flow
Amamitha we-Coriolis Flow ancike emthethweni weCoriolis, okubangela ishubhu elivuthazayo ukujiya ngokulingana nesilinganiso sokugeleza kwesisindo se-fluid. Lokhu kusonteka kusetshenziselwa ukukala isilinganiso sokugeleza ngokunembile. Zifanelekile ukukala ukugeleza koketshezi kanye namagesi ezimbonini ezahlukahlukene, kufaka phakathi amakhambi nama-petrochemicals.
4. Vortex Shepling Flow Meters
Amamitha we-Vortex achithe amamitha alinganise ukugeleza ngokuthola ama-vortices asungulwe phansi komzimba okubunjiwe okubekwe emfuleni ogelezayo. Zisetshenziswa kuzinhlelo zokusebenza lapho ukuthembeka nokulungiswa okuphansi kubalulekile, njengokulinganisa kokugeleza komoya ezitshalweni zamandla.
Imitha yokugeleza - Izimiso Zokusebenza
Ukuqonda imigomo yokusebenza kubalulekile ekukhetheniImitha yokugeleza kwesokudla kwesicelo esithile. Ake sihlole kafushane izimiso ezisebenzayo zawo womabili amamitha okugeleza kwama-mechanic kanye nama-elekthronikhi.
A. Imitha yokugeleza - Imishini Yokugeleza Kwemishini Yokusebenza Imigomo Yokusebenza
Mechanic Flow Meters asebenza ngokususelwa kwizakhiwo ezibonakalayo njengokunyakaza kwento (rotor, ukuntanta, noma i-piston), izinguquko ekucindezelweni, noma ukuthuthwa koketshezi. Lawa mamitha ahlinzeka ngokufundwa okuqondile ngokusekelwe kulezi zinguquko ezingokomzimba, ukuzenza zilungele izinhlelo zokusebenza ezahlukahlukene.
I-B. Imitha yokugeleza - Imigomo Yokusebenza Nge-Electronic Meters Esebenzayo
Ngakolunye uhlangothi amamitha we-elekthronikhi, ngakolunye uhlangothi, sebenzisa ubuchwepheshe besimanje njengezinkundla ze-electromagnetic, amaza e-ultrasonic, amabutho e-coriolis, noma ukuchitha ama-vortex ukukala amanani okugeleza. Lawa mamitha ahlinzeka ngemininingwane yedijithali futhi ajwayele ukunemba futhi ahlukahlukene ngokwedlula abalingani babo bemishini. Ukusebenza kwabo kubandakanya izinzwa kanye ne-elekthronikhi eguqula izilinganiso zomzimba zibe ukufundwa kwedijithali.
Imitha yokugeleza - Izindlela zokukhetha
1. Izakhiwo ze-Fluid:Ukukhethwa kwemitha yokugeleza kufanele kuvumelane nezakhiwo zoketshezi ezilinganiswa. Izici ezifana ne-viscosity, ubuntu, kanye nokulinganiselwa kwamakhemikhali kudlala indima ebalulekile. Izinhlobo ezahlukahlukene zemitha yokugeleza zilungele kangcono uketshezi ezinezakhiwo ezahlukahlukene.
2. Ibanga lokulinganisa lokugeleza:Ukunquma uhla olulindelwe lokugeleza kubalulekile. Amamitha okugeleza amamitha aklanyelwe amanani athile okugeleza, futhi akhethe eyodwa ehambelana nobubanzi bohlelo lwakho kubalulekile ukuze kuqinisekiswe izilinganiso ezinembile.
3. Izidingo zokunemba:Ukunemba kubaluleke kakhulu ezimbonini eziningi. Cabanga ngezinga elidingekayo lokunemba bese ukhetha imitha yokugeleza ehlangabezana nalezo zindinganiso. Ezinye izinhlelo zifuna ukunemba okuphezulu, kanti ezinye zivumela ukunemba okuphansi.
4. Ukufakwa kokufakwa:Imvelo yokufaka ingathinta ukusebenza kwemitha yokugeleza. Izici ezifana nosayizi wepayipi, ukuqondisisa, kanye nokutholakala kufanele kubhekwe ukuze kuqinisekiswe ukufakwa okufanele.
I-5. Izindleko nokulungiswa:Ukwazi izindleko kuyisici kunoma yimuphi umsebenzi. Ukuhlola zombili izindleko zokuqala zemitha yokugeleza nezindleko eziqhubekayo zokulungisa kubalulekile. Amanye amamitha adinga ukulinganisa okujwayelekile nokulungiswa, kanti amanye anakekelwa kakhulu.
Ukugcina
Imitha yokugelezaAmathuluzi asemqoka athola izinhlelo zokusebenza kuyo yonke imboni, aqinisekise ukukalwa okunembile nokulawulwa kwamanani okugeleza koketshezi. Ukukhetha phakathi kwamamitha okugeleza kwama-mechanical ne-elekthronikhi kuya ngezinto ezifana nohlobo lwamanzi, izinga lokugeleza, kanye nezinga lokunemba okudingekayo. Ukuqonda imigomo yokusebenza nezinhlobo ezahlukahlukene zamamitha wokugeleza atholakalayo ekwenzeni izinqumo ezinolwazi ekukhetheni ithuluzi elifanele kunoma yisiphi isicelo esithile.
Umkhiqizi wemitha we-Flow Flow: Shanghai Boqu Intrence Co, Ltd. Umenzi ovelele owaziwa ngokukhiqiza uhla lwamamitha aphezulu aphezulu, ukunakekela ezidingweni ezahlukahlukene zezimboni emhlabeni wonke. Ukuzibophezela kwabo ekususweni nasekucacelweni kubenza babe igama elimethembayo emkhakheni wokulinganisa wokugeleza.
