Isingeniso

Uhlobo lokufaka imitha yokugeleza kwegesi eshisayo ingenye yemitha yohlobo lokugeleza kwesisindo.
Idumile ezinhlelweni zezimboni yindlela eziklanywe ngayo futhi zakhiwe ngayo. Isici asizona izingxenye ezihambayo, cishe ezingavinjwanga ziqonde endleleni yokugeleza, azidingi ukulungiswa kwezinga lokushisa noma ingcindezi futhi sigcine ukunemba phezu kwenani elibanzi lokugeleza. Ukugijima kwamapayipi aqondile kungancishiswa ngokusebenzisa izakhi ze-dual-plate flow conditioning futhi ukufakwa kulula kakhulu ngokungena okuncane kwamapayipi.
Uhlobo lokufaka usayizi wemitha yokugeleza kwegesi eshisayo ukusuka ku-DN40~DN2000mm.

Izinzuzo

Uhlobo lokufaka lwe-thermal gas flow meter okuthuthukile :
(1)Isilinganiso sobubanzi obubanzi 1000:1;
(2)I-diameter enkulu, izinga lokugeleza eliphansi, ukulahlekelwa kwengcindezi enganakwa;
(3)Isilinganiso sokugeleza kwesisindo esiqondile ngaphandle kwesinxephezelo sezinga lokushisa nengcindezi;
(4)Izwela kakhulu isilinganiso esiphansi sokugeleza;
(5)Kulula ukuklama nokukhetha, kulula ukuyifaka nokusebenzisa;
(6)Ifanele zonke izinhlobo zesilinganiso sokugeleza kwegesi okukodwa noma okuxubile
(7) Inzwa ayinazo izingxenye ezihambayo kanye nezingxenye ezizwa ukucindezela, futhi ayithinteki ukudlidliza ekunembeni kwesilinganiso. Inokusebenza okuhle kokuzamazama komhlaba kanye nokuthembeka okuphezulu kokulinganisa;
(8) Akukho ukulahlekelwa kwengcindezi noma ukulahlekelwa kwengcindezi encane kakhulu.
(9) Lapho kukala ukugeleza kwegesi, kuvame ukuvezwa kuyunithi yokugeleza kwevolumu ngaphansi kwesimo esivamile, futhi izinga lokushisa eliphakathi/ushintsho lokucindezela alithinti neze inani elilinganisiwe. Uma ukuminyana kungashintshi esimweni esivamile (okungukuthi, ukwakheka akushintshile), kuyefana nemitha yokugeleza kwesisindo;
(10) Indlela yokufaka i-plug-in, ukufakwa nokugcinwa ngaphandle kokumisa ukukhiqiza, kulula ukuyisebenzisa nokuyinakekela;
(11) Sekela izindlela zokuxhumana eziningi, njengokuxhumana kwe-RS485, iphrothokholi ye-MODBUS, njll., ekwazi ukubona ukuzenzakalelayo kwefekthri nokuhlanganiswa

Isicelo

Uhlobo lokufaka isicelo semitha yokugeleza kwegesi eshisayo:
Imitha yokugeleza komoya yegesi eshisayo isetshenziswa kabanzi kumandla kagesi, ukuhlanzwa kwamanzi, imboni ye-Petrochemical, i-Glass, Ceramics kanye nemboni Yezinto Zokwakha, futhi isetshenziselwa ikakhulukazi ukukala Igesi Eyomile, efana Nomoya, Igesi Yemvelo, igesi ye-LPG, i-Biogas, ect.Kodwa eshisayo ukugeleza okukhulu kwegesi akukwazanga ukusetshenziswa ukukala uMhwamuko, igesi yokuswakama ne-ethyne.

Ukufakwa

Uhlobo lokufaka ukufakwa kwemitha yegesi eshisayo egelezayo:
① Kungakhathaliseki ukuthi i-flowmeter ifakwe iqonde noma ivundlile, gcina i-flowmeter isesimweni esivundlile.
② Ezimeni lapho ukuma kwegesi ngephutha noma isitobhu segesi sengozi nakanjani kuzodala ukulahlekelwa okukhulu okungahlehliseki, i-bypass kufanele ifakwe.
③ Kufanele okungenani kube nengxenye yepayipi eqondile engu-10D ngaphambi kwe-flowmeter kanye no-5D (D ububanzi bepayipi) ingxenye yepayipi eqondile ngemuva.
④ Uma ithuluzi lifakwe ngaphandle, umthunzi welanga kufanele wengezwe ukugwema ilanga nemvula.
⑤ Qinisekisa ukuthi ayikho inkambu kazibuthe enamandla, inkambu eqinile kagesi nokudlidliza komshini okuqinile eduze kwe-flowmeter.
⑥ Isisekelo esimile se-flowmeter kufanele sithembeke, kodwa asinakwabelwana ngaso nokugxilisa okuqinile kwamanje.
⑦ Indawo ezungezile kufanele iqinisekise ukuthi awukho umphumela olimazayo kungxubevange ye-aluminium.
⑧ Qinisekisa ukuthi isiqondiso sokugeleza kwegesi sihambisana nesiqondiso somcibisholo ku-flowmeter.
⑨ Imisebenzi yokushisela ayivunyelwe endaweni eneziqhumane.

Ukulungiswa kwemitha yokugeleza kwegesi eshisayo yohlobo lokufaka:
Ekusebenzeni kwansuku zonke kwe-flowmeter yegesi eshisayo, hlola futhi uhlanze i-flowmeter, qinisa izingxenye ezixekethile, thola futhi ubhekane nokungajwayelekile kwe-flowmeter esebenza ngesikhathi, qinisekisa ukusebenza okuvamile kwe-flowmeter, unciphise futhi ubambezele ukuguga. izingxenye, Nweba impilo yesevisi ye-flowmeter. Amanye ama-flowmeters azokonakala ngemva kokusetshenziswa isikhathi esithile, futhi kufanele ahlanzwe ngokucotshwa njll. kuye ngezinga lokungcoliswa kwalo.
