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

Vavulocator (yomwe imadziwikanso kuti: Pneumatic valve locator) ndiye chida chachikulu chowongolera valavu, nthawi zambiri chimakhala ndi valavu yolamulira ya Pneumatic Pneumatic, imavomereza chizindikiro chowongolera, kenako ndi chizindikiro chake chotulutsa kuti chiwongolere valavu yowongolera chibayo, pomwe valavu yowongolera, tsinde la valavu la mayankho osunthira kudzera pa chipangizo chomakina kupita ku choyika ma valve, momwe ma valve amakhalira kudzera pamagetsi kupita kumtunda.
Kapangidwe ka valavu:
Vavu poyika molingana ndi kapangidwe kake ndi mfundo zogwirira ntchito zitha kugawidwa kukhala choyimira valavu cha pneumatic, choyika valavu yamagetsi-gasi ndi choyika valavu wanzeru.
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 yogwira ntchito ya valve positioner
Choyimira 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.

Gulu la ma valve poyika
Valve positioner imagawidwa mu pneumatic valve positioner ndi magetsi 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 imathanso kutenga P>
Ma valve pneumatic amagwiritsidwa ntchito kwambiri pamakampani opanga mphamvu zamagetsi
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 zidzathandiza, adalandiranso abwenzi ambiri, valavu ya pneumatic Chitukuko cha pneumatic valve actuator chapita patsogolo pang'onopang'ono, ndipo makina otsika mtengo a single chip microcomputer ndi microprocessor yatsopano azidziwitso adzalowa m'malo mwa kutsanzira magawo amagetsi amagetsi. kukhala gawo lalikulu lowongolera lamagetsi amagetsi amagetsi, kenako malizitsani dongosolo lathunthu lowongolera digito.

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.
