Udindo wa pneumatic valve positioner Pneumatic valve imagwiritsidwa ntchito kwambiri pamakampani opanga mphamvu zamagetsi

Udindo wa valavu ya pneumatic valve positioner Pneumatic valve imagwiritsidwa ntchito kwambiri m'makampani amagetsi amagetsi amagetsi Valve locator (yomwe imadziwikanso kuti: Pneumatic valve locator) ndiye zida zazikulu zowongolera ma valve, nthawi zambiri zimakhala ndi valavu yowongolera ya Pneumatic Pneumatic, imavomereza chizindikiro chowongolera, ndi ndiye ku chiwongolero chake chotuluka kuti chiwongolere valavu yolamulira ya Pneumatic, pamene valavu yolamulira, tsinde la valve la kusuntha kwaposachedwa kudzera mu chipangizo cha makina kupita ku valavu, chikhalidwe cha valve kupyolera mu chizindikiro chamagetsi kupita kumtunda wapamwamba. Kapangidwe ka valavu: Choyimira valavu molingana ndi mawonekedwe ake ndi mfundo zogwirira ntchito zitha kugawidwa m'malo opangira valavu ya pneumatic, choyika valavu yamagetsi-gasi ndi malo anzeru a valve. Valve positioner imatha kuwonjezera mphamvu yotulutsa valavu yowongolera, kuchepetsa kufalikira kwa chizindikiro chowongolera, kufulumizitsa kuthamanga kwa tsinde la valavu, kuwongolera mzere wa valavu, kuthana ndi kukangana kwa tsinde la valavu ndikuchotsa chikoka cha valve. mphamvu yosagwirizana, kuti atsimikizire malo olondola a valavu yoyendetsa. Valve positioner ADAPTS zosiyanasiyana Ma actuators omwe amagwiritsidwa ntchito kwambiri amagawidwa kukhala ma pneumatic actuators, magetsi oyendetsa magetsi, sitiroko yowongoka, sitiroko ya ngodya. Amagwiritsidwa ntchito potsegula ndi kutseka mitundu yonse ya ma valve ndi ma air plates okha komanso pamanja. Mfundo yogwirira ntchito ya valve positioner Choyika valavu ndicho chowonjezera chachikulu cha valve yolamulira. Zimatengera chizindikiro chosinthira tsinde la valavu ngati chizindikiro choyezera mayankho, imatenga chizindikiro chowongolera ngati chizindikiro chokhazikitsa, kufananiza, pamene awiriwo ali ndi kupatuka, amasintha chizindikiro chake kukhala chowongolera, chimapangitsa kuti chiwongolero chichitike, chimakhazikitsa tsinde la valve. nthawi zosamuka ndi chizindikiro chowongolera pakati pa makalata amodzi ndi amodzi. Chifukwa chake, choyimira valavu chimakhala ndi njira yowongolera mayankho ndi kusuntha kwa tsinde ngati chizindikiro choyezera komanso kutulutsa kowongolera ngati chizindikiro chokhazikitsa.

Kugawika kwa ma valve positioner Valve positioner imagawidwa kukhala pneumatic valve positioner ndi electro valve positioner malinga ndi chizindikiro cholowera. Chizindikiro cholowera cha choyimira cha voliyumu cha pneumatic ndi chizindikiro chokhazikika cha gasi, mwachitsanzo, 20 ~ 100kPa chizindikiro cha gasi, chizindikiritso chake chomwe chimatuluka ndi chizindikiro chokhazikika cha gasi. Chizindikiro cholowera chamagetsi amagetsi ndi chizindikiro chapano kapena voteji, mwachitsanzo, 4 ~ 20mA chizindikiro chapano kapena 1 ~ 5V voteji chizindikiro, etc., chizindikiro chamagetsi chimasinthidwa kukhala mphamvu yamagetsi mkati mwa choyika chamagetsi chamagetsi, kenako chizindikiro cha gasi chotuluka ku valavu yowongolera. Malinga ndi malangizo a zochita akhoza kugawidwa mu njira imodzi valavu positioner ndi njira ziwiri valavu positioner. Choyimitsira valavu cha njira imodzi chimagwiritsidwa ntchito mu pisitoni actuator, choyimitsa valavu chimangogwira mbali imodzi, choyimira cha valavu chanjira ziwiri chimagwira mbali zonse za silinda ya pisitoni actuator, mbali ziwiri. Malinga ndi kutulutsa kwa valavu ndi chizindikiro chopezera chizindikiro chagawika kukhala choyika valavu chabwino ndi choyimira valavu. Pamene chizindikiro cholowetsa ku choyikapo cha valve chikukwera, chizindikiro chotuluka chimawonjezeka, kotero kuti phindu limakhala labwino. Chizindikiro cholowetsa cha rection valve positioner chimawonjezeka, chizindikiro chotuluka chimachepa, chifukwa chake, phindu ndiloipa. Malingana ndi chizindikiro cholowera cha valve ndi chizindikiro cha analogi kapena chizindikiro cha digito, chikhoza kugawidwa m'magawo wamba a valve ndi malo opangira magetsi a basi. Chizindikiro cholowetsa cha locator wamba valavu ndi kuthamanga kwa analogi kapena pakalipano, siginecha yamagetsi, chizindikiro cholowera cha fieldbus Electric valve locator ndi chizindikiro cha digito cha fieldbus. Kutengera ngati choyika valavu chili ndi CPU, chitha kugawidwa m'malo wamba amagetsi amagetsi ndi choyika chanzeru chamagetsi. Ma valve odziwika bwino amagetsi alibe CPU, choncho alibe nzeru, sangathe kugwira ntchito zanzeru. Intelligent valve positioner yokhala ndi CPU, imatha kugwira ntchito zanzeru, mwachitsanzo, imatha kupititsa patsogolo chipukuta misozi, etc., fieldbus electrical valve positioner ingathenso kubweretsedwa Pneumatic valves amagwiritsidwa ntchito kwambiri pamakampani amagetsi amagetsi Tsatirani kuthamanga kwamagetsi. mphamvu zamagetsi zamagetsi ndi mafakitale owongolera valavu, ndi chitukuko cha makina opangira magetsi amagetsi amachitidwanso sitepe ndi sitepe, sekondi iliyonse muzinthu zanzeru zanzeru zimawonekeranso pang'onopang'ono, panthawiyo zida zonse zoyendetsera mafakitale zamakono zimabweretsanso ku malo ogulitsa. ithandizadi, idalandiranso abwenzi ambiri, valavu ya pneumatic Chitukuko cha pneumatic valve actuator chapita patsogolo pang'onopang'ono. Chipangizo chotsika mtengo cha single chip microcomputer ndi chidziwitso chatsopano cha microprocessor chidzalowa m'malo mwa magawo otsanzira amagetsi amagetsi kuti akhale gawo lalikulu lamagetsi amagetsi amagetsi, kenako kumaliza dongosolo lonse lamagetsi. Tsatirani kuthamanga kwa ukadaulo wamagetsi amagetsi ndi mafakitale owongolera ma valve, komanso kukula kwa makina opangira ma valve amagetsi kumachitikanso pang'onopang'ono, sekondi iliyonse muzinthu zanzeru zanzeru zimawonekeranso pang'onopang'ono, panthawiyo zida zonse zowongolera mafakitale zamasiku ano nazonso. zimabweretsa kumsika zidzathandizadi, adalandiranso abwenzi ambiri, valavu ya pneumatic Chitukuko cha pneumatic valve actuator chapita patsogolo pang'onopang'ono.

Chizoloŵezi pazida ndi mawonekedwe ogwiritsira ntchito mankhwala amakono omwe akusowa pakukula kwa kumasuka komanso kosavuta panthawi yothamanga, makamaka, ambiri a ma valve actuators adzaukira kusintha koonekeratu, ndithudi ndandanda ndi chizindikiritso cha parameter kuchokera ku ulamuliro wochepa. idzakhala * * kupititsa patsogolo kayendetsedwe ka kayendetsedwe ka ma valve amagetsi. Zogwirizana ndi ma valve a pneumatic ndi hydraulic, ma wiring osavuta komanso ntchito zamphamvu ndikupitiliza kukulitsa kukula kwa ntchito. Chifukwa valavu ya pneumatic mu netiweki ya chitoliro nthawi zambiri imatsegulidwa ndikutsekedwa pafupipafupi, kulongedza sikumakalamba kuti asunge kusindikiza kwa nthawi yayitali.
