Kodi mungathetse bwanji vuto la choyika valavu yamagetsi? Ubwino ndi kuipa kwa valavu yamagetsi ndi valavu ya pneumatic valavu yamagetsi yamagetsi, yomwe imadziwikanso kuti pneumatic valve positioner, ndiye zida zazikulu za chowongolera, chomwe nthawi zambiri chimagwiritsidwa ntchito ndi chowongolera chibayo, chimalandira chizindikiro cha chowongolera, kenako ndi chizindikiro chake. kulamulira pneumatic regulator, pamene chowongolera, kusamutsidwa kwa tsinde la valavu ndi kupyolera mu makina opangira ndemanga kwa choyika valavu, malo a valve kupyolera mu chizindikiro chamagetsi kupita kumtunda wapamwamba. Kupyolera mu zaka zoposa 20 za kudzikundikira zinachitikira, ndi akatswiri amisiri ndi valavu yamagetsi positioner kusanthula zomveka pamodzi ndi chiwerengero chachikulu cha zochitika kukonzanso munda, valavu yamagetsi positioner gulu zolakwa, kusanthula chifukwa cha vuto ndi kupeza njira zothetsera mavuto, I. Ndikuyembekeza kupatsa ogwira ntchito kuyika ndi kukonza zolakwika za actuator kapena kukonza kwatsiku ndi tsiku kwa valavu yamagetsi kuti athandizire. 1. Kusinthasintha kwamphamvu kwa mpweya kwa choyika valavu yamagetsi Yang'anani chochepetsera mpweya wa fyuluta, pansi pa madzi ndi dothi. 2, choyimira valavu yamagetsi chimakhala ndi chizindikiro cholowera koma zotulutsa zake ndizochepa kapena ayi Chifukwa chakusintha kopitilira muyeso kwa chotchingira chapaulendo, koyilo ya mota yama torque imakhala yopanda weld, ndipo chowongoleracho chimatha kuwotcherera. Mawaya a torque motor amathyoka kapena kuwotcha chifukwa chakuchulukira; Gwiritsani ntchito multimeter kuti muyese kukana kwa koyilo. Nthawi zambiri, iyenera kukhala pafupifupi 250. Ngati kupatuka kwa 250 L kuli kwakukulu, m'malo mwa koyiloyo. Kulumikizana kwa chingwe kwa siginecha ndikosavuta; Yang'anani ma waya kuti muchotse kumasula. Kulumikiza chingwe cha siginecha kwabwezedwa: Onani ngati (+) (-) cholumikizira chasinthidwa. Malo ododometsa a Nozzle siwolondola: sinthani kufanana, onani kusintha kwakusintha. Zomangira zomangira mphuno zotayirira: limbitsani zomangira za nozzle kuti zikwaniritse zofunikira paulendo. Amplifier ndi yolakwika; Yang'anani ngati amplifier ndi yolakwika kapena musinthe. Kutsekeka kwa mpweya: Gwiritsani ntchito 0,12 kuti mudutse dothi. Kutsekeka kwa mpweya: Mpando wapansi wa locator, pali mpweya wotuluka, ngati simusamala kutsekeka, wopezekayo amasiya kugwira ntchito. Baffle lever kugwirizana kasupe deformation kapena wosweka; Tsegulani chivundikiro cha malo ndikusintha. Sinthani mtengo wa maginito okhazikika ndikuwona ngati valavu ikugwira ntchito. Ndemanga ya lever imagwa; Konzani kufanana kwake ndikuwona momwe valavu imagwirira ntchito. Ndemanga za lever osiyanasiyana pin skew: Sinthani pini kuti ikwaniritse zofunikira paulendo. Valavu yoyang'anira yokhala ndi gudumu lamanja simagunda pamalo apakati; Yang'anani valavu yachitetezo cha handwheel ndikuisintha kukhala yapakati. Kutaya CAM kapena malo osayenera; Limbitsani CAM kapena sinthani malo a CAM. Hydraulic control valve flapper lever spring stiffness sikokwanira: kusintha (+) (-) polarity wiring, sinthani mtunda pakati pa flapper ndi nozzle, kukwaniritsa zofunikira paulendo (ndiye muyenera kusintha njira yowongolera). 3, valavu yamagetsi yamagetsi yotulutsa kuthamanga kwa oscillation Dothi mu amplifier: Dothi mu amplifier. Mapaipi otulutsa kapena kutulutsa mutu wa filimu: chotsani kutayikira, pangani valavu kugwira ntchito bwino. Film mutu diaphragm kukalamba: m'malo ukalamba diaphragm kungakhale. Kulakwitsa kosatha kwa maginito: sinthani kufanana kwa maginito okhazikika kuti muthetse kusakhazikika kwa maginito. Loose screw fixing feedback lever: zomangira zomangira zosefera kuti muchepetse kugwedezeka kwa ma valve. Chigawo chachikulu cha AC cha chizindikiro cholowetsa: chotsani chigawo cha AC kapena kufanana ndi capacitor pamapeto olowera. Sefa kusokoneza kwa AC. Msewu wakumbuyo wakumbuyo uli ndi dothi: chotsani dothi, kuthetsa mavuto. Vavu ndodo yozungulira kumasula: yang'anani valavu yowongolera. 4, valavu yamagetsi yamagetsi ilibe zolowera ndi zotuluka Chotsekereza block: Tsekani dothi. Ngati malo a chosinthira chodziwikiratu ndi chamanja sichili cholakwika, chosinthira chodziwikiratu ndi chowongolera chidzasinthidwa mozungulira mpaka pomwe valavu yoyang'ana yokha. 5. Kulondola kwa valavu yamagetsi sikuli bwino Nozzle, kusintha kwa mbale sikuli bwino: sinthani parallelism kapena nozzle fixing screw, kukwaniritsa zofunikira zolondola. Chipata valavu kumbuyo kuthamanga mpweya kutayikira; Chotsani kutulutsa mpweya. Kusuntha kwa ma radial kwa valve yowongolera ndi yayikulu: yang'anani valavu yowongolera. Kusintha kolakwika kwa screw zeroed: Sinthani skruu ya zero kuti ikwaniritse zofunikira. Lever ya ndemanga ndi cholakwika chosagwirizana ndi malo a pini: Bwezeretsani malo a pini molingana ndi zofunikira paulendo. Ubwino ndi kuipa kwa mtunda wa valavu ya pneumatic ndi yayikulu kuposa valavu yamagetsi, liwiro la valavu ya pneumatic litha kusinthidwa, mawonekedwe osavuta, osavuta kuwongolera, pochitapo kanthu chifukwa cha mawonekedwe a mpweya wokhawokha, osati zosavuta kuonongeka ndi kupanikizana, koma ayenera kukhala ndi gwero la mpweya, ndipo dongosolo lake lolamulira ndilovuta kwambiri kuposa valavu yamagetsi. Kuyankha kwa mavavu a pneumatic ndikofulumira, kotetezeka komanso kodalirika, mafakitale ambiri omwe ali ndi zofunikira zowongolera kwambiri amapangidwira zida zowongolera zida zama pneumatic zomwe zimakhazikitsa ma air station. Zamagetsi zikutanthauza magetsi.
