Imitha yokugelezazingamathuluzi abalulekile asetshenziswa ezimbonini ezahlukahlukene ukukala izinga lokugeleza koketshezi noma amagesi.Badlala indima ebalulekile ekuqapheni nasekulawuleni ukuhamba koketshezi, okubalulekile ezinhlobonhlobo zezinhlelo zokusebenza.Kule bhulogi, sizongena emhlabeni wamamitha okugeleza, sihlole incazelo yawo, inhloso, kanye nokubaluleka kwawo kuzo zonke izimboni ezihlukahlukene.
I-Flow Meter - Incazelo kanye Nenhloso
I-flow meter, njengoba negama liphakamisa, iyithuluzi eliklanyelwe ukukala izinga uketshezi olugeleza ngalo epayipini noma epayipini.Inikeza ulwazi olubalulekile mayelana nenani loketshezi oludlula endaweni ethile ohlelweni.Le datha ibalulekile ngezinjongo eziningi, njengamakhasimende akhokhayo ngokusetshenziswa kwamanzi noma igesi, ukuqinisekisa ukusebenza kahle kwezinqubo zezimboni, nokuqapha izimo zemvelo.
I-Flow Meter - Ukubaluleka Ezimbonini Ezihlukahlukene
Amamitha okugeleza angamathuluzi abalulekile ezimbonini eziningi.Nazi ezinye izibonelo zokubaluleka kwazo:
1. Imboni kawoyela negesi:Amamitha okugeleza asetshenziselwa ukukala ukugeleza kukawoyela ongahluziwe, igesi yemvelo, nemikhiqizo ehlukahlukene ecolisisiwe, esiza ekudluliseleni esitokisini, ekuqaphelweni kwemithombo, kanye nokuphathwa kwamapayipi.
2. Imboni Yamakhemikhali:Izinqubo zamakhemikhali ngokuvamile zihlanganisa ukukalwa okunembile kwamazinga okugeleza koketshezi ukuze kuqinisekiswe ukuxubana okulungile kwezithako nokuvikela izingozi zokuphepha.
3. Ukwelapha Amanzi:Ezitshalweni zokuhlanza amanzi, ama-flow metres asiza ekunqumeni inani lamanzi angenayo naphumayo endaweni, aqinisekise ukuphathwa kahle nokusabalalisa.
4. Ezemithi:Imboni yezokwenziwa kwemithi incike kuma-flow metres ukuze ithole isilinganiso esinembile sezithako ekukhiqizweni kwezidakamizwa.
5. Ezolimo:Amamitha okugeleza asetshenziswa ezinhlelweni zokuchelela ukuze kuphathwe kahle imithombo yamanzi.
6. Ukudla Nesiphuzo:Izitshalo zokucubungula ukudla zisebenzisa ama-flow metres ukuqapha ukuhamba kwezithako, okusiza ukugcina ikhwalithi yomkhiqizo engaguquki.
7. Umkhakha wezamandla:Izitshalo zamandla nezinsiza zisebenzisa ama-flow metres ukukala ukugeleza koketshezi oluhlukahlukene, okuhlanganisa isitimu namanzi okupholisa, ukuze kuthuthukiswe ukukhiqizwa kwamandla.
Manje, ake sihlole izinhlobo ezahlukene zamamitha okugeleza.
Flow Meter - Izinhlobo Flow Meter
Amamitha okugeleza afika ngezinhlobo ezahlukahlukene, ngalinye linezimiso zalo ezihlukile zokusebenza nezinhlelo zokusebenza.Angahlukaniswa kabanzi ngamaqembu amabili amakhulu: amamitha okugeleza kwemishini namamitha okugeleza kwe-elekthronikhi.
A. Flow Meter - Mechanical Flow Meter
1. Ama-Rotameters
I-Rotameters, eyaziwa nangokuthi amamitha okugeleza kwendawo eguquguqukayo, asebenza ngomgomo wento entantayo (imvamisa i-float noma i-piston) ekhuphukayo noma ewela ngaphakathi kweshubhu eliyindilinga njengoba izinga lokugeleza lishintsha.Indawo ye-elementi ibonisa izinga lokugeleza.Avame ukusetshenziselwa ukulinganisa amazinga okugeleza asuka phansi kuye-kumaphakathi wamagesi noketshezi.
2. I-Turbine Flow Meters
Amamitha okugeleza kwe-turbine asebenzisa i-rotor ejikelezayo ebekwe endleleni yoketshezi.Ijubane le-rotor lilingana nezinga lokugeleza, livumela izilinganiso ezinembile.Lawa mamitha ajwayele ukuqashwa ezimbonini ezifana ne-petroleum, amakhemikhali, nokuphathwa kwamanzi.
3. Positive Displacement Flow Meters
Amamitha okugeleza okuhamba kahle akala ivolumu yoketshezi ngokuthwebula nokubala amavolumu ahlukene oketshezi.Anembe kakhulu futhi afaneleka ukulinganisa amazinga okugeleza aphansi kokubili uketshezi lwe-viscous nolungenayo i-viscous.
4. I-Differential Pressure Flow Meters
Amamitha okugeleza kokucindezela okuhlukile, okuhlanganisa amapuleti e-orifice namashubhu e-venturi, asebenza ngokudala ukwehla kwengcindezi phakathi kokuncishiswa kwendlela yokugeleza.Umehluko wengcindezi usetshenziselwa ukubala izinga lokugeleza.Lawa mamitha ahlukahlukene futhi asetshenziswa kabanzi.
B. Flow Meter — Electronic Flow Meters
1. I-Electromagnetic Flow Meters
Amamitha okugeleza kagesi asebenza ngesimiso somthetho kaFaraday wokungeniswa kwe-electromagnetic.Zilungele ukukala ukugeleza koketshezi lwe-conductive futhi zivame ukusetshenziswa ekuhlanzeni amanzi, ekulawuleni amanzi angcolile, nasekucutshungulweni kwamakhemikhali.
2. Ultrasonic Flow Meters
Amamitha okugeleza kwe-Ultrasonic asebenzisa amaza e-ultrasonic ukukala amazinga okugeleza.Awaphazamisi futhi angakala uketshezi oluningi, okuhlanganisa uketshezi namagesi.Lawa mamitha abalulekile ezimbonini ezifana ne-HVAC, izinsiza zamandla, namanzi.
3. I-Coriolis Flow Meters
Amamitha okugeleza kwe-Coriolis ancike kumphumela we-Coriolis, obangela ukuba ishubhu elidlidlizayo lisonte ngokulingana nezinga lokugeleza kwesisindo soketshezi.Lokhu kusonteka kusetshenziselwa ukukala izinga lokugeleza ngokunembile.Zifanele ukulinganisa ukugeleza kwakho kokubili uketshezi namagesi ezimbonini ezihlukahlukene, kuhlanganise nemithi kanye namakhemikhali e-petrochemicals.
4. I-Vortex Shedding Flow Meters
I-Vortex shedding flow metre ikala ukugeleza ngokuthola ama-vortices akheke ezansi nomzimba we-bluff obekwe kumfudlana wokugeleza.Asetshenziswa ezinhlelweni lapho ukuthembeka nokunakekelwa okuphansi kubalulekile, njengokukalwa kokugeleza kwesitimu ezitshalweni zamandla.
I-Flow Meter - Izimiso Zokusebenza
Ukuqonda izimiso zokusebenza kubalulekile ekukhetheniimitha yokugeleza yesokudla yohlelo oluthile.Ake sihlole kafushane izimiso zokusebenza zakho kokubili amamitha okugeleza ngomshini kanye ne-elekthronikhi.
A. I-Flow Meter - Izimiso Zokusebenza Zemichanical Flow Meter
Amamitha wokugeleza kwemishini asebenza ngokususelwe ezintweni ezibonakalayo njengokunyakaza kwento (irotha, ukuntanta, noma i-piston), izinguquko kungcindezi, noma ukususwa koketshezi.Lawa mamitha ahlinzeka ngokufundwa okuqondile okusekelwe kulezi zinguquko zomzimba, okuwenza afanelekele izinhlelo zokusebenza ezihlukahlukene.
B. Flow Meter — Electronic Flow Meters Working Principles
Ngakolunye uhlangothi, amamitha okugeleza kwe-elekthronikhi asebenzisa ubuchwepheshe besimanje njengezinkambu kazibuthe kagesi, amaza e-ultrasonic, amandla e-Coriolis, noma ukuchithwa kwe-vortex ukukala amazinga okugeleza.Lawa mamitha ahlinzeka ngedatha yedijithali futhi ngokuvamile anembe kakhulu futhi aguquguqukayo kunozakwabo bemishini.Ukusebenza kwabo kuhlanganisa izinzwa nezinto zikagesi eziguqula izilinganiso zomzimba zibe ukufundwa kwedijithali.
I-Flow Meter - Imibandela Yokukhetha
1. Izici Zoketshezi:Ukukhethwa kwemitha yokugeleza kufanele kuhambisane nezimpawu zoketshezi olulinganiswayo.Izinto ezifana ne-viscosity, ukuminyana, nokuhambisana kwamakhemikhali zidlala indima ebalulekile.Izinhlobo ezihlukene zamamitha okugeleza zifaneleka kangcono uketshezi olunezici ezihlukene.
2. Ibanga Lesilinganiso sokugeleza:Ukunquma ibanga lokugeleza elilindelekile kubalulekile.Amamitha okugeleza adizayinelwe izilinganiso zokugeleza ezithile, futhi ukukhetha eyodwa efana nobubanzi bohlelo lwakho lokusebenza kubalulekile ukuze uqinisekise izilinganiso ezinembile.
3. Izidingo Zokunemba:Ukunemba kubaluleke kakhulu ezimbonini eziningi.Cabangela izinga elidingekayo lokunemba bese ukhetha imitha yokugeleza ehlangabezana nalawo mazinga.Ezinye izinhlelo zokusebenza zidinga ukunemba okuphezulu, kuyilapho ezinye zivumela ukunemba okuphansi.
4. Ukucatshangelwa kokufakwa:Indawo yokufaka ingaba nomthelela ekusebenzeni kwemitha yokugeleza.Izinto ezinjengosayizi wamapayipi, umumo, nokufinyeleleka kufanele kucatshangelwe ukuze kuqinisekiswe ukufakwa okufanele.
5. Izindleko Nokunakekela:Ukuqaphela izindleko kuyisici kunoma iyiphi iphrojekthi.Ukuhlola kokubili izindleko zokuqala ze-flow meter kanye nezindleko zokulungisa okuqhubekayo kubalulekile.Amanye amamitha adinga ukulinganiswa nokunakekelwa okuvamile, kanti amanye anokunakekelwa okuphansi kakhulu.
Isiphetho
Imitha yokugelezaingamathuluzi abalulekile athola izinhlelo zokusebenza kuzo zonke izimboni eziningi, aqinisekisa ukulinganisa okunembile kanye nokulawula amazinga okugeleza kwamanzi.Ukukhetha phakathi kwamamitha okugeleza kwemishini nekagesi kuncike ezintweni ezifana nohlobo loketshezi, izinga lokugeleza, kanye nezinga lokunemba elidingekayo.Ukuqonda izimiso zokusebenza kanye nezinhlobo ezihlukahlukene zama-flow metres atholakalayo kubalulekile ekwenzeni izinqumo ezinolwazi ekukhetheni ithuluzi elifanele lanoma yisiphi isicelo esithile.
Umkhiqizi we-Flow Meter: I-Shanghai BOQU Instrument Co., Ltd. ingumkhiqizi ovelele owaziwa ngokukhiqiza amamitha okugeleza amaningi ekhwalithi ephezulu, ebhekelela izidingo ezihlukene zezimboni emhlabeni jikelele.Ukuzibophezela kwabo ekusunguleni izinto ezintsha nokunemba kubenza babe igama elithenjwayo emkhakheni wokulinganisa ukugeleza.
