Wanzeru Valve electro-pneumatic Positioner

Valve positioner , chowonjezera chachikulu cha valavu yoyendetsa, choyimira valavu ndiye chowonjezera chachikulu cha valve yoyendetsa, yomwe imagwiritsidwa ntchito kulamulira mlingo wotsegulira wa valavu ya pneumatic kapena magetsi kuti atsimikizire kuti valavu ikhoza kuyima molondola ikafika pa zomwe zinakonzedweratu. udindo. Kupyolera mu kuwongolera kolondola kwa malo a valve, kusintha kolondola kwamadzimadzi kungathe kupezedwa kuti akwaniritse zosowa za mafakitale osiyanasiyana. Ma valve poyika ma valve amagawidwa m'magawo a pneumatic valve, ma electro-pneumatic valve positioners ndi anzeru ma valve positioners malinga ndi kapangidwe kawo. Amalandira chizindikiro chotulutsa chowongolera ndiyeno amagwiritsa ntchito chizindikiro chotulutsa kuti aziwongolera valavu yowongolera pneumatic. Kusunthika kwa tsinde la valve kumabwezeretsedwa ku choyika valavu kudzera pa chipangizo chamakina, ndipo mawonekedwe a valavu amaperekedwa kumtunda wapamwamba kudzera pa chizindikiro chamagetsi.

Pneumatic valve positioners ndiye mtundu wofunikira kwambiri, kulandira ndi kudyetsa ma siginecha kudzera pamakina.

Electro-pneumatic valve positioner imaphatikiza ukadaulo wamagetsi ndi pneumatic kuti upangitse kulondola komanso kusinthasintha kwa kuwongolera.
Wopanga ma valve wanzeru amayambitsa ukadaulo wa microprocessor kuti akwaniritse makina apamwamba kwambiri komanso kuwongolera mwanzeru.
Zoyika ma valve zimagwira ntchito yofunika kwambiri pamakina opanga makina, makamaka pakafunika kuwongolera bwino kayendedwe ka madzimadzi, monga mafakitale amafuta, mafuta, ndi gasi. Amalandira zizindikiro kuchokera ku kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.
