Muyeso wa njira zamafakitale,ma transmitter opanikizika osiyanasiyanaali ndi udindo wozindikira magawo ofunikira monga kusiyana kwa kuthamanga, mulingo wamadzimadzi ndi kayendedwe ka madzi. Chotumizira cha DP chimayesa kusiyana kwa kuthamanga pakati pa mfundo ziwiri ndipo chinthu chake chozindikira (diaphragm capsule) ndi chosavuta. Kuyika kapena kugwiritsa ntchito molakwika—monga, kuyambitsa kupanikizika kwakukulu mwadzidzidzi kumbali imodzi—kungathe kuwononga kapena kuwononga kotheratu chotumizira. Monga chida cholondola chomwe chimagwiritsidwa ntchito poyesa ndi kuwongolera kupanga, kugwira ntchito kwake kotetezeka komanso kolondola kumadalira kwambiri pa manifold yogwirizana ndi valavu.
Chosinthira cha kupanikizika chosiyana chimafunikira manifold a valve makamaka pazifukwa zotsatirazi:
Chofunikira pa chitetezo:Chotumizira cha DP chimayesa kusiyana kwa kuthamanga kwa mpweya pakati pa zipinda zake zokhala ndi kuthamanga kwa mpweya kwakukulu ndi kochepa. Ngati ma valve mbali zonse ziwiri sagwira ntchito bwino panthawi yoyambitsa, kuzimitsa kapena kukonza, chotumiziracho chikhoza kupatsidwa kuthamanga kwa mpweya kwathunthu mbali imodzi yokha, zomwe zingawononge diaphragm yofewa. Valavu yolinganiza yomwe ili mu manifold imapereka njira yolumikizira kuthamanga kwa mpweya mbali zonse ziwiri isanayambe kugwiritsidwa ntchito ngati kapangidwe kofunikira komwe kamaletsa kuwonongeka kwa makina.
Chofunikira pa calibration:Chida chilichonse choyezera sichimasuntha ndi zero. Chotumizira cha DP chimafuna kuti chizindikiro chake chotulutsa chiyang'aniridwe ndikusinthidwa kukhala zero yeniyeni pomwe kupanikizika kosiyana kuli zero. Mwa kutseka ma valve a block ya H ndi L ndikutsegula valavu yolinganiza, mkhalidwe weniweni wa zero-differential-pressure ukhoza kupangidwa popanda kusokoneza njirayi, zomwe zimapangitsa kuti zero calibration ya pa intaneti iwonetsetse kuti kuyeza kwa nthawi yayitali ndi kolondola.
Chofunikira pa kukonza:Mizere ya mpweya imatha kusonkhanitsa mpweya, madzi oundana kapena dothi, zomwe zimapangitsa kuti chizindikirocho chisokonezeke kapena kutsekeka. Chifukwa chake, ma valve apadera amafunika kuti mpweya utuluke, kutulutsira madzi (kuwononga) ndi kutsuka.
Ma valvu atatu ndi omwe amagwiritsidwa ntchito kwambiri pa transmitter ya DP. Amapangidwa ndi ma valve awiri olekanitsa njira (block) ndi valavu imodzi yolinganiza pakati. Pa nthawi ya ntchito yanthawi zonse, ma valve awiri olinganiza amakhala otseguka ndipo valavu yolinganiza imatsekedwa, zomwe zimathandiza kuti njira yolandirira ilowe m'zipinda zopanikizika zabwino ndi zoyipa za transmitter motsatana ndikuyesa kuthamanga kwa nthawi yeniyeni. Komabe, panthawi yoyambitsa kapena kutseka, njira yogwirira ntchito "choyamba tsegulani valavu yolinganiza, kenako yendetsani (tsegulani kapena tsekani) ma valve olinganiza" iyenera kutsatiridwa mosamala. Cholinga chake ndikuletsa kupanikizika kwa mbali imodzi kwa transmitter. Ngati kuthamanga kwambiri kwayambitsidwa mwadzidzidzi mbali imodzi, kuthamanga kwakukulu kwa unidirectional static kumatha kuwononga nthawi yomweyo diaphragm ya sensor yofooka - chomwe chimayambitsa kulephera kwa chipangizo. Valavu yolinganiza imasunga kuthamanga kwa H & L m'zipinda zokhazikika panthawi yonse yodzaza kapena kutsitsa kupanikizika, potero kuteteza sensa.
Manifold a ma valve asanu amamangidwa pa kapangidwe ka ma valve atatu powonjezera ma valavu owonjezera mbali iliyonse ya H & L pressure. Kapangidwe ka manifold a ma valve asanu kamakhala ndi ma valve awiri otsekeka, valavu imodzi yofanana ndi ma valve awiri otulutsira madzi kapena kutulutsa mpweya. Mwachidule, manifold a ma valve asanu amaphimba ntchito zonse za manifold a ma valve atatu ndipo amakwaniritsa kusintha kwakukulu pakusinthasintha kwa magwiridwe antchito komanso kukonza mosavuta.
Mu ntchito yeniyeni, pa miyeso yokhudza zakumwa zoyera kapena mpweya wopanda zodetsa, zomwe sizimaundana kapena sizimafuna kuponderezedwa pafupipafupi, manifold a ma valve atatu amatha kukwaniritsa zofunikira zonse. Zitsanzo zikuphatikizapo kuyeza kuyenda kwa madzi pa mapaipi a mpweya wopanikizika kapena kuyeza mulingo m'madzi oyeretsedwa, komwe sing'anga ndi yoyera komanso yokhazikika, mizere ya impulse singathe kutsekedwa ndipo sikufunika kukonza kwambiri. Pazochitika zotere, manifold a ma valve atatu ndi chisankho chotsika mtengo komanso chodalirika. Bola ngati ogwiritsa ntchito atsatira njira zoyezera ma valve, manifold amatha kugwira ntchito popanda mavuto kwa nthawi yayitali.
Komabe, m'malo opangira zinthu, sing'anga nthawi zambiri siingakhale yabwino kwenikweni. Poyesa nthunzi, mpweya wodzaza ndi fumbi kapena matope, kusungunuka kwa condensate kapena kutsekeka kwa tinthu tating'onoting'ono m'mizere ya impulse kungayambitse kuchedwa kwa muyeso, zolakwika kapena kulephera. Muzochitika izi, ma valve awiri otulutsira madzi a ma 5-valve manifold amalola kuchotsa madzi ndi condensate pa intaneti popanda kusokoneza mizere ya impulse kapena kutseka kuzungulira konse koyezera. Akatswiri a zida zam'munda amangofunika kutseka ma valve a block ndikutsegula ma valve a drain; kenako amatha kusonkhanitsa zinyalala mu chidebe kapena kutsuka ndi nthunzi kuti ayeretsedwe mwachangu. Ichi ndi njira yabwino kwambiri yokhazikitsira petrochemical ndi magetsi yomwe imafuna kupitiriza kwa kupanga, kukonza bwino ntchito komanso kuchepetsa chiopsezo cha kupopera kwapakati kapena kutuluka kwa madzi.
Kaya kusankha manifold a ma valvu atatu kapena 5 a valavu imodzi ya chipangizo choyezera kuthamanga kwapadera kuyenera kusankhidwa kutengera zofunikira za polojekitiyi, kuphatikiza momwe zinthu zilili, kapangidwe kake, ndi njira yogwirira ntchito ndi kukonza.Shanghai Wangyuanndi wopanga waluso kwambiri pakupanga zida, wokhala ndi zaka zoposa 20 zakuchitikira mumakampani. Ngati muli ndi zosowa kapena mafunso okhudza kusankhama transmitter opanikizika osiyanasiyanandi ma valve manifolds, chonde musazengereze kulankhulana ndi Shanghai Wangyuan kuti mupeze njira yoyenera yoyezera.
