Makina anayi ndi a waya ndi waya wopatsirana

Ambiri aogonthazakhazikitsidwa patsamba, ndipo zizindikiro zawo zotuluka zimatumizidwa kuchipinda chowongolera, ndipo mphamvu zake zimachokera kuchipinda chowongolera. Nthawi zambiri pamakhala njira ziwiri za kufanitsa kufala ndi kupezeka kwa magetsi kwa "

(1) Makina Awiri

Magetsi ndi chizindikiro chotulutsa chimafalikira ndi mawaya awiri motsatana, ndipo njira yowonera imawonetsedwa pa Chithunzi 2.3. Zofananira ngati izi zimatchedwa ma aya otumiza maya. Kutulutsa kwa ma DDZ-ⅱ mndandanda wazotsatira kumatengera mawonekedwe a chivindikiro. Magetsi amatha kukhala ac (220v) kapena DC (24V), ndipo chizindikiro chotulutsa chimatha kukhala zire (0-10MA) kapena Zero (4-20MA).

Chithunzi cha 2.3 4-waya

(1) dongosolo lachiwiri

Pamitundu iwiri ya waya, pali mawaya awiri okha omwe amalumikizidwa ndi tromistter, ndipo mawayilesi awiri awa amapereka mphamvu magetsi nthawi yomweyo, monga tikuonera pa Chithunzi 2.4. Itha kuwoneka kuti mphamvu, zotumiza komanso zotsutsana ndi katundu zimalumikizidwa mu mndandanda womwe umagwirizana ndi gawo lomwe limayesedwa ndi gawo loyezedwa. Pamene njira yoyeserera yoyenga, kuwerengera kofanana ndi kusintha kwa transtiveter moyenerera, motero amayendanso kudzera mu katundu amasinthanso.

Chithunzi 2.4

Makina a kaya awiri ayenera kukumana ndi izi:

①

, Ndiye kuti

Popeza mzere wamagetsi ndi chingwe chofala ndizachilendo, mphamvu zoperekedwa kwa tromiction ndi magetsi zimaperekedwa ndi zilembo zamagetsi. Ngati zotulutsa za transtiter zili m'munsi, ziyenera kutsimikiziridwa kuti zitsimikiziro za semiconductor mkati mwake zomwe zingagwirabe bwinobwino.

Chifukwa chake, malire am'munsi ya zamakono sangathe kutsika kwambiri. Chifukwa kumapeto kwa zotsatira za zotulutsa, chipangizo cha semiconductor chiyenera kukhala ndi malo ogwiritsira ntchito zowerengeka, ndipo mphamvu zogwirira ntchito zimafunikira kuperekedwa ndi magetsi, motero zamakono ziyenera kukhala ndi mfundo zero. Chizindikiro chaposachedwa chaposachedwa chimatengera 4-20Madc, chomwe chimapanga mikhalidwe yopanga magetsi awiri.

② The Mphamvu yamagetsi ya tranceter kuti igwire ntchito nthawi zonse

Mu fomula:Kodi magetsi otulutsa "omwewo ndi omwendi mtengo wochepera wa mphamvu yamagetsi;ndiye malire apamwamba a zotulukapo, nthawi zambiri 20ma;Kodi mtengo wokhazikika wa tramisterter;ndiye mtengo wotsutsa wa waya wolumikiza.

Kutumiza kwa waya uyenera kukhala ndi mphamvu imodzi ya DC. Kutulutsa kwamphamvu kwa mphamvu kumatanthauza mphamvu zotheka ndi zero monga malo oyambira, m'malo mwa mphamvu zabwino komanso zoyipa zomwe zimapangitsa kuti zigwirizane ndi magetsi a zero. Kutulutsa kwamphamvu kwa ma transmitter ndi ofanana ndi kusiyana pakati pa magetsi opangira magetsi ndi kuponya volping vl ndi kukana r ya waya. Pofuna kuonetsetsa kuti ntchito yotumiza pafupipafupi, mtengo wowonjezera mphamvu umangosintha mkati mwa zingapo. Ngati katundu wanu akukana ukuwonjezeka, mphamvu ya magetsi imayenera kuwonjezeka; Kupanda kutero, mphamvu ya magetsi imatha kuchepa; Ngati mphamvu ya mphamvu ya magetsi ikayamba, kukana katundu kumafunika kuchepa; Kupanda kutero, kukana katundu kungawonjezeredwe.

Mphamvu yothandiza yogwira ntchito yotumiza pafupipafupi

Popeza kuchuluka kwa magetsi kwa mahuni awiri ndi ochepa kwambiri, ndipo mafuta a volipiwa amasintha kwambiri ndi zotsatirapo zomwe zilipo ndi zomwe zimapangitsa kukana, magetsi ogwiritsira ntchito gawo lililonse la mzerewu limasintha kwambiri. Chifukwa chake, popanga waya wamafuta awiri, ndikofunikira kugwiritsa ntchito mphamvu yotsika ya ogwira ntchito ndikukhazikitsa ulalo wamagetsi komanso ulalo wapano ndi ntchito yabwino.

Kutumiza kwa waya ziwiri kumakhala ndi zabwino zambiri, zomwe zingachepetse kwambiri mtengo wa chipangizocho, ndipo ali ndi chitetezo komanso chitetezo cha kuphulika. Chifukwa chake, maiko ambiri padziko lapansi amagwiritsa ntchito ma aya-abodza.
