Positioner

Kampani ya Hankun imatha kupereka zida zonse zopangira ma pneumatic actuators monga ma switch switch, ma valve solenoid, zowongolera zosefera mpweya, zoyikapo, etc. zofunika kasitomala.

Valve positioner ndi chipangizo chomwe chimalandira zizindikiro zofooka za 4-20mA kuchokera kwa woyang'anira kapena dongosolo lolamulira, ndikutumiza zizindikiro za mpweya kwa pneumatic actuator kuti azilamulira malo a valve.

Ma valavu amatha kugawidwa m'magawo a pneumatic valve, ma electro-pneumatic valve positioners ndi ma valve positioning anzeru malinga ndi kapangidwe kawo ndi mfundo zogwirira ntchito.

Choyimitsa valavu chimatha kuwonjezera mphamvu yotulutsa valavu yowongolera, kuchepetsa kusanja pakufalitsa chizindikiro chowongolera, kufulumizitsa kuthamanga kwa tsinde la valavu, kuwongolera mzere wa valavu, kuthana ndi kukangana kwa tsinde la valve ndikuchotsa mphamvu yosagwirizana.Kuti mutsimikizire kuyika kolondola kwa valve yowongolera.

Amagwiritsidwa ntchito molumikizana ndi pneumatic actuated control valve kuti apange loop yotseka yotseka.Chizindikiro chachindunji chomwe chimaperekedwa ndi dongosolo lowongolera chimasinthidwa kukhala chizindikiro cha gasi choyendetsa valavu yowongolera kuti igwire ntchito ya valve yolamulira.Panthawi imodzimodziyo, mayankho amachitidwa molingana ndi kutsegulidwa kwa valve yolamulira, kotero kuti malo a valve akhoza kukhazikitsidwa molondola malinga ndi kutulutsa chizindikiro chowongolera ndi dongosolo.

Oyimilira wamba amaphatikiza oyika makina omwe ali ndi mtengo wokwera kwambiri komanso oyika anzeru okhala ndi luntha lapamwamba.
