Indlela yokuxazulula iphutha le-valve positioner kagesi? Izinzuzo kanye nobubi be-valve kagesi kanye ne-pneumatic valve positioner kagesi, eyaziwa nangokuthi i-pneumatic valve positioner, iyizinsiza eziyinhloko zesilawuli, ngokuvamile esisetshenziswa nesilawuli somoya, yamukela isignali yokuphuma yesilawuli, bese kuthi ngesignali yayo yokuphuma. ukulawula isilawuli se-pneumatic, lapho isenzo somlawuli, ukugudluzwa kwesiqu se-valve futhi ngempendulo yedivayisi ewumshini ukuya endaweni yevalvu, ukuma kwevalvu ngesignali kagesi ukuya ohlelweni olungaphezulu. Ngokuqoqwa kweminyaka engaphezu kwengu-20 yokuhlangenwe nakho, kanye nonjiniyela bezobuchwepheshe kanye nokuhlaziywa okunengqondo kwe-valve ye-valve kuhlanganiswe nenani elikhulu lesipiliyoni sokulungisa insimu, ukuhlukaniswa kwephutha le-valve kagesi, ukuhlaziya imbangela yephutha kanye nokuthola indlela yokuxazulula izinkinga, ngethemba ukunikeza izisebenzi zamathuluzi ekufakweni nasekulungiseni iphutha kwe-actuator noma ukunakekelwa kwansuku zonke kwesimo se-valve kagesi ukusiza. 1. Ukuguquguquka komfutho womthombo womoya we-valve positioner kagesi Hlola isinciphisi somfutho wokuhlunga umoya, phansi kwamanzi nokungcola. 2, indawo yokubeka i-valve kagesi inesignali yokokufaka kodwa okukhiphayo kuncane noma cha Ngenxa yokulungiswa ngokweqile kwesikulufu sokunquma uhambo sendawo, ikhoyili yenjini yetorque ayinakushiswa, futhi umthofu ungashiselwa. Ikhoyili ye-torque motor yangaphakathi iyanqamuka noma iphele ngenxa yokudlula i-current; Sebenzisa i-multimeter ukukala ukumelana namakhoyili. Ngokujwayelekile, kufanele ibe ngu-250. Uma ukuchezuka ku-250 L kukukhulu kakhulu, buyisela ikhoyili. Ukuthinta ikhebula lesiginali kubi; Hlola amatheminali ezintambo ukuze ususe ukuxega. Ukuxhumeka kwekhebula lesiginali kuhlehlisiwe: Hlola ukuthi uxhumano lwetheminali (+)(-) luhlehlisiwe yini. Ukuma kwe-nozzle baffle akulungile: lungisa ukufana, bona ukuguqulwa kokuphumayo. Isikulufu sokulungisa umlomo wombhobho oxekethile: qinisa isikulufu sokulungisa umlomo wombhobho ukuze uhlangabezane nezidingo zokuhamba. I-amplifier inephutha; Hlola ukuthi i-amplifier inephutha noma ishintshe. Ukuvinjwa umoya: Sebenzisa u-0.12 ukudlulisa ukungcola. Ukuvinjwa kwe-vent: isihlalo esiphansi se-locator, kukhona i-nozzle vent, uma unganaki ukuvinjelwa, indawo ekhona izoyeka ukusebenza. I-Baffle lever uxhumano spring deformation noma ephukile; Vula ikhava yendawo bese uyishintsha. Shintsha isigxobo sikazibuthe unomphela futhi uhlole ukuthi i-valve iyasebenza yini. I-lever yempendulo iyawa; Lungisa ukufana futhi ubone ukuthi i-valve isebenza kanjani. Impendulo yebanga lephinikhodi egxilile: Lungisa iphinikhodi ukuze lihlangabezane nezidingo zohambo. I-valve elawulayo enesondo lesandla ayishayi endaweni emaphakathi; Hlola i-valve yokuphepha yendawo yesandla bese uyilungisa endaweni emaphakathi. I-CAM evulekile noma isikhundla esingalungile; Qinisa i-CAM noma lungisa indawo ye-CAM. Ukuqina kwe-valve ye-hydraulic control valve flapper akwanele: shintsha (+)(-) izintambo ze-polarity, lungisa ibanga phakathi kwe-flapper ne-nozzle, ukuhlangabezana nezidingo zokuhamba (bese kudingeka ushintshe imodi yesilawuli). 3, i-electric valve positioner pressure oscillation Ukungcola ku-amplifier: Ukungcola ku-amplifier. Ipayipi lokukhipha noma ukuvuza kwekhanda lefilimu: susa ukuvuza, yenza i-valve isebenze kahle. Film ikhanda diaphragm ukuguga: esikhundleni diaphragm ukuguga kungaba. Iphutha elihlala njalo lokuphambukisa kazibuthe: lungisa ukufana kukazibuthe unomphela ukuze uqede ukungazinzi kwesekethe kazibuthe. Isikulufa sokulungisa isikulufu esixegayo esixegayo: isikulufu sokuqinisa isihlungi ukuze kuqedwe ukudlidliza kwevalvu. Ingxenye enkulu ye-AC yesiginali yokufaka: susa ingxenye ye-AC noma uhambisane ne-capacitor ekugcineni kokufaka. Hlunga ukuphazamisa kwe-AC. Umgwaqo womoya ocindezela emuva unokungcola: susa ukungcola, ukuxazulula izinkinga. I-valve rod radial loosening: hlola i-valve elawulayo. I-4, i-valve positioner kagesi ayinakho okokufaka nokuphumayo I-backpressure block: Vimba ukungcola. Uma indawo ye-othomathikhi kanye ne-manual switch ingalungile, i-othomathikhi kanye ne-manual switch izozukiswa ngokwewashi endaweni ye-valve yokuhlola okuzenzakalelayo. 5. Ukunemba kwesimo se-valve kagesi akukuhle I-Nozzle, ukulungiswa kwepuleti lokumisa akulungile: lungisa isikulufu sokulungisa i-parallelism noma i-nozzle, uhlangabezane nezidingo zokunemba. I-valve yesango i-back pressure ukuvuza komoya; Susa ukuvuza komoya. I-radial displacement ye-valve elawulayo inkulu: hlola i-valve elawulayo. Ukulungiswa okungalungile kwesikulufu esiyiziro: Lungisa isikulufu esiziro ukuze sihlangabezane nezidingo zokunemba. I-lever yempendulo kanye nephutha lokungafani kwendawo yephinikhodi egxilile: Setha kabusha indawo yephinikhodi ngokuya ngezidingo zokuhamba. Izinzuzo kanye nokubi kwebanga lesenzo se-valve yomoya likhulu kune-valve kagesi, isivinini sesenzo sokushintsha kwe-valve ye-pneumatic singalungiswa, isakhiwo esilula, ukusinakekela kalula, ngesikhathi sesenzo ngenxa yezimpawu ze-buffer zegesi ngokwayo, hhayi kulula ukulinyazwa yi-jamming, kodwa kufanele ibe nomthombo womoya, futhi uhlelo lwayo lokulawula luyinkimbinkimbi kune-valve kagesi. Impendulo yevalvu yomoya iyashesha, iphephile futhi inokwethenjelwa, izimboni eziningi ezinezidingo zokulawula eziphezulu zenzelwe izinto zokulawula insimbi yomoya esetha isiteshi somoya esicindezelwe. Ugesi usho ugesi.
