Zotumiza mphamvuKawirikawiri amapangidwa kuti asonkhanitse deta m'mafakitale, omwe amatha kutulutsa zizindikiro zokhazikika komanso kupereka njira zowongolera deta yokhazikika komanso yodalirika. Kuchokera pamalingaliro a mfundo zoyezera, kuthamanga kwa sing'anga yoyezedwa sikungokhala gawo lokhalo la njira yodziwikiratu - kwenikweni kumawonetsa makhalidwe ophatikizana a madzimadzi a sing'anga pansi pa mikhalidwe yosasunthika komanso yosinthasintha. Mwa kugwiritsa ntchito mokwanira ubale wamkati, ndizotheka kupeza magawo ofunikira a njira monga mulingo wamadzimadzi ndi kuchuluka kwa madzi kuchokera ku miyeso ya chotumizira cha kupanikizika popanda kuwonjezera masensa owonjezera. Ubwino wapaderawu umapangitsa kuti zotumizira za kupanikizika zikhale zofunika kwambiri popanga mayankho odalirika kwambiri a muyeso m'makina ovuta a mafakitale.
Kuyeza kwa Mlingo Wopanikizika Wosasunthika
Pa madzi osasuntha, kuthamanga kwa madzi kosasunthika pa kuya kulikonse kungafotokozedwe ndi fomula ya kuthamanga kwa madzi P = ρgh. Kutengera ndi mfundoyi, chizindikiro chotulutsa cha chotumizira kuthamanga chimasonyeza ubale wolunjika ndi kutalika kwa mlingo wa madzi. Njira yoyezera ndi yoyenera makamaka pazochitika zovuta zogwirira ntchito ndi ntchito zomwe zimafuna kuyankhidwa mwachangu. Mtundu uwu wa muyeso ungagwiritsidwe ntchito kwambiri pazochitika monga matanki osungira mankhwala, ziwiya zophikira mankhwala ndi malo osungira madzi otayira m'matauni.
Mu ntchito zamafakitale,zotumizira zomwe zimalowa m'madzindi ma transmitter achizolowezi opanikizika onse amagwira ntchito motsatira mfundo yoyezera kuthamanga kwa mpweya, koma amasiyana mu kapangidwe kake, kuyika, ndi zochitika zoyenera. Ma transmitter olowa m'madzi ndi ang'onoang'ono komanso osavuta kuyika, ndipo sensor probe imayikidwa pansi pa madzi kwa nthawi yayitali. Ndi abwino kwambiri m'malo monga zitsime zakuya, matanki amadzi ndi ziwiya zosungiramo madzi zotseguka. Ma transmitter opanikizika amayikidwa kunja kwa chidebecho ndipo amatha kuthana ndi kutentha kwambiri komanso njira zaukhondo kudzera mu njira mongachisindikizo cha diaphragmndi ma capillary akutali.
Kuyeza kwa Kupanikizika Kosiyanasiyana
Mu chidebe chotsekedwa chomwe chili ndi kuthamanga kwa mpweya wosinthasintha, kugwiritsa ntchito chotumizira mpweya chokha kumabweretsa kuchuluka kwa kuthamanga kwa hydrostatic ndi kuthamanga kwa mpweya, komwe sikungawonetse kuchuluka kwenikweni kwa madzi. Chifukwa chake,chopatsira cha kupanikizika kosiyana (DP)iyenera kugwiritsidwa ntchito, kulumikiza mbali ya kupanikizika kwakukulu pansi (kupanikizika kosasinthasintha + kupanikizika kwa gawo la gasi) ndi mbali ya kupanikizika kochepa pamwamba (kupanikizika kwa gawo la gasi kokha). Powerengera kusiyana kwa kupanikizika, kusokoneza kuchokera ku kupanikizika kwa gawo la gasi kumachotsedwa, zomwe zimapangitsa kuti chizindikiro chigwirizane ndi kuchuluka kwa madzi. Mtundu uwu wa kuyeza umagwiritsidwa ntchito kwambiri mu ma reactor a mankhwala, mizati yothira ndi ntchito zina komwe kuwongolera kukhazikika kwa mulingo pansi pa mikhalidwe yopanikizika kumafunika. Pa kutentha kwakukulu komanso zofalitsa zamphamvu,dongosolo la capillary la flange ziwiriKawirikawiri imakonzedwa kuti ipatule njira yogwirira ntchito kuti isakhudze mwachindunji ndi chinthu chozindikira, motero imawonjezera kukhazikika kwa chipangizocho kwa nthawi yayitali m'mikhalidwe yovuta kwambiri.
Kuyeza Kuthamanga Kosiyanasiyana kwa Kupanikizika
Maziko a muyeso wa DP flow ndi akuti madzi akamayenda kudzera mu chipangizo cholumikizira (cholumikizira cha orifice, annubar, ndi zina zotero), kusintha kwa flow cross-section kumapangitsa kuti flow speed isinthe moyenera ndikupanga kusiyana kwa pressure kudutsa throttling element yomwe ili ndi ubale wodziwika bwino ndi flow flow. Poyesa molondola kusiyana kwa pressure ndi DP transmitter, flow speed imatha kudziwika mwanjira ina. Chifukwa cha mulingo wake wapamwamba wa standardization, kusinthasintha kwabwino, komanso kuyenerera pansi pa zovuta,Ma flowmeter ozikidwa pa DPKhalani ndi malo osasinthika mu muyeso wa kuyenda kwa nthunzi ndi mpweya ndi chotumizira chosiyana cha kuthamanga chimagwira ntchito yofunika kwambiri ngati chinthu chowunikira pakati.
Chotumizira mpweya wopanikizika si chipangizo chomwe chimangopereka kuwerenga kokha, phindu lake lenileni lili mu kutanthauzira mozama komanso kugwiritsa ntchito mosavuta deta yoyezera. Kumvetsetsa mokwanira ndikugwiritsa ntchito mwaluso ubale weniweni womwe uli kumbuyo kwa deta yoyezera mpweya kungatsegule njira zogwira mtima komanso zolondola zowongolera njira ndi kukonza makina. Pokhala katswiri pakupanga ndi kupereka zida kwa zaka zoposa 20,Shanghai Wangyuanyadzipereka kupatsa makasitomala zinthu ndi ntchito zokhazikika komanso zodalirika. Kaya muli ndi zosowa kapena mafunso okhudzana ndi kusankha kapena kugwiritsa ntchito ma transmitter opanikizika, chonde musazengereze kulankhulana nafe. Tidzasangalala kukupatsani mayankho aukadaulo komanso anthawi yake.
