Chida Chamagetsi cha Valvendi chida chofunikira kwambiri pakuyendetsa kuti muzindikire kuwongolera pulogalamu ya valve, kuwongolera zokha komanso kuwongolera kutali.Kusuntha kwake kumatha kuyendetsedwa ndi stroke, torque kapena axial thrust.Chifukwa mawonekedwe ogwiritsira ntchito chipangizo chamagetsi a valve ndi kugwiritsa ntchito kwake kumadalira mtundu wa valavu, mawonekedwe a chipangizo ndi valavu mu payipi kapena malo a zipangizo.

1. Sankhani Electric Actuator Malinga ndi Valve Type

1.1 Angle Stroke Electric actuator (Angle<360 °) ndi yoyenera valavu ya butterfly, valve ya mpira, plug valve, etc.
Kuzungulira kwa shaft kwamagetsi kwamagetsi osakwana sabata imodzi, yomwe ili yochepera 360 °, nthawi zambiri 90 ° kuti mukwaniritse njira yotsegula ndi kutseka njira.Mtundu uwu wa actuator yamagetsi malinga ndi kuyika kwa mawonekedwe osiyanasiyana umagawidwa kukhala mtundu wolumikizidwa mwachindunji, mtundu wachiwiri wa crank.

A) Kulumikizana kwachindunji: kumatanthauza shaft yotulutsa magetsi yolumikizidwa mwachindunji ndi tsinde la valve munjira yoyika.

B) Mtundu wa crank Base: umatanthawuza shaft yotuluka kudzera pa crank ndi tsinde yolumikizira.

1.2 Multi-turn electric actuators (Angle> 360°) ya mavavu a pachipata, ma valve a globe, ndi zina zotero. valavu yotsegula ndi kutseka ndondomeko.

1.3 Sitiroko yowongoka (kuyenda molunjika) ndi yoyenera pampando umodzi wowongolera valavu, valavu yoyendetsa mipando iwiri, ndi zina zotero.Kusuntha kwa shaft yotulutsa yamagetsi ndi mzere, osati mozungulira.

2. Dziwani njira yoyendetsera makina opangira magetsi malinga ndi zofunikira zoyendetsera ntchito yopanga

2.1 Switch type (open loop control) switch type actuators magetsi nthawi zambiri amapereka chiwongolero chotseguka kapena chotsekedwa cha valavu, kaya pamalo otseguka kapena otsekedwa kwathunthu, ma valve oterowo safuna kuwongolera kolondola kwa media.Ndikoyenera kutchulanso kuti chosinthira chamagetsi chamtundu wamagetsi chikhoza kugawidwa m'magawo awiri ndi mawonekedwe ophatikizika chifukwa chamitundu yosiyanasiyana.Kusankha mtundu kuyenera kupangidwa ku izi, kapena kumachitika nthawi zambiri pakukhazikitsa ndikuwongolera dongosolo ndi zochitika zina zosagwirizana.

A) Kapangidwe kagawidwe (komwe kumadziwika kuti mtundu wamba): Chigawo chowongolera chimasiyanitsidwa ndi cholumikizira magetsi.The actuator magetsi sangathe kulamulira valavu palokha, koma ayenera kuwongoleredwa ndi zina ulamuliro unit.Kuipa kwa kapangidwe kameneka ndikuti sikoyenera kukhazikitsa dongosolo lonse, kumawonjezera mawaya ndi kuyika mtengo, ndipo kumakhala kosavuta kuwoneka ngati cholakwika, cholakwika chikachitika, sikoyenera kuzindikira ndikusunga, chiŵerengero cha ntchito-mtengo. sizoyenera.

B) Mapangidwe Ophatikizidwa (omwe amadziwika kuti Monolithic) : Chigawo chowongolera chimaphatikizidwa ndi chowongolera chamagetsi ndipo chimatha kugwiritsidwa ntchito pamalopo popanda gawo lowongolera lakunja, ndipo chingagwiritsidwe ntchito patali pokhapokha potulutsa zidziwitso zoyenera zowongolera.Ubwino wa dongosololi ndikuthandizira kukhazikitsidwa kwa dongosolo lonse, kuchepetsa ma waya ndi kuyika ndalama, kuzindikira kosavuta komanso kuthetsa mavuto.Koma zida zachikhalidwe zophatikizika zamapangidwe zimakhalanso ndi malo ambiri opanda ungwiro, chifukwa chake zapanga chowongolera chanzeru chamagetsi.

2.2 Chosinthika (chotsekedwa-loop control) chosinthika chamagetsi chamagetsi sichimangokhala ndi ntchito yosinthira-mtundu wophatikizika, komanso imatha kuwongolera bwino valavu ndikusintha kayendedwe kapakati.
A) Chizindikiro chamtundu wamagetsi (panopa, voteji) chowongolera chowongolera magetsi nthawi zambiri chimakhala ndi chizindikiro (4 ~ 20MA, 0 ~ 10MA) kapena siginecha yamagetsi (0 ~ 5V, 1 ~ 5V).

B) Mtundu wa ntchito (mtundu wotseguka wamagetsi, mtundu wapafupi wamagetsi) mtundu wa malamulo amagetsi ogwiritsira ntchito magetsi nthawi zambiri amakhala mtundu wotseguka wamagetsi (4 ~ 20MA kuwongolera mwachitsanzo, mtundu wotseguka wamagetsi ndi chizindikiro cha 4MA chofanana ndi valavu yotsekedwa, 20MA yogwirizana ndi valavu yotseguka), mtundu wina ndi mtundu wotsekedwa wamagetsi (4-20MA kulamulira mwachitsanzo, mtundu wotseguka wamagetsi ndi chizindikiro cha 4MA chofanana ndi valavu yotseguka, 20MA yofanana ndi valve yotsekedwa).

C) Kutayika kwa chitetezo cha chizindikiro kumatanthawuza kuti woyendetsa magetsi amatsegula ndi kutseka valavu yolamulira ku mtengo wachitetezo chokhazikitsidwa pamene chizindikiro chowongolera chikutayika chifukwa cha vuto la dera, etc.

3. Dziwani torque yotulutsa yamagetsi molingana ndi torque yomwe ikufunika kuti mutsegule ndi kutseka valavu.Mphuno yomwe imafunika kuti mutsegule ndi kutseka valavu imatsimikizira kuchuluka kwa mphamvu yomwe magetsi amasankha, yomwe nthawi zambiri imaperekedwa ndi wogwiritsa ntchito kapena yosankhidwa ndi wopanga valavu Monga wopanga makina amangokhalira kutulutsa torque ya actuator, torque imafunika. chifukwa chotsegula ndi kutseka kwa valve kumatsimikiziridwa ndi zinthu monga kukula kwa valve orifice, kuthamanga kwa ntchito, ndi zina zotero. Wopanga valavu yemweyo wa mawonekedwe omwewo Pamene kusankha kwa actuator Torque ndi yaying'ono kwambiri kumayambitsa valavu yotsegula ndi kutseka, kotero woyendetsa magetsi ayenera kusankha makokedwe oyenera.

4. Malinga ndi kugwiritsiridwa ntchito kwa chilengedwe ndi kuphulika kwa kalasi yamagetsi a zipangizo zamagetsi malinga ndi kugwiritsa ntchito chilengedwe ndi zofunikira za kalasi ya kuphulika, zipangizo zamagetsi zikhoza kugawidwa mumtundu wamba, mtundu wakunja, mtundu wamoto, mtundu wakunja wamoto. ndi zina zotero.

5. Maziko Osankha Valve Electric Chipangizo Molondola:

5.1 Torque yogwiritsira ntchito: torque yogwiritsira ntchito ndiyo gawo lofunika kwambiri posankha chipangizo chamagetsi cha valve, mphamvu yamagetsi yamagetsi iyenera kukhala 1.2 ~ 1.5 nthawi za Torque yogwira ntchito kwambiri.

5.2 Kuthamanga Kwambiri: Pali mitundu iwiri ikuluikulu ya ma valve actuator: imodzi ndi yotulutsa torque molunjika popanda thrust plate, ndipo inayo ndi kukhala ndi thrust plate yokhala ndi torque yotulutsa yomwe imasinthidwa kukhala tsinde la nati mu thrust plate.

5.3 Nambala Yozungulira ya Shaft Yotulutsa: valavu yamagetsi yotulutsa shaft yozungulira nambala ya kuchuluka kwa makhoti okhala ndi m'mimba mwake mwadzina la valavu, phula tsinde la valve, kuchuluka kwa ulusi, kuwerengera malinga ndi m = H / Zs (m ndi chiwerengero cha kutembenukira kuti chipangizo chamagetsi chiyenera kukhutitsa, h ndi kutalika kwa valve yotsegula, s ndi tsinde loyendetsa ulusi, Z ndiye mutu wa ulusi).

5.4 Stem Diameter: Valve yamitundu yambiri yozungulira siyingasonkhanitsidwe ngati kutalika kwa tsinde komwe kumaloledwa ndi chipangizo chamagetsi sikungadutse tsinde la valve yoperekedwa.Choncho, magetsi chipangizo dzenje linanena bungwe kutsinde m'mimba mwake ayenera kukhala wamkulu kuposa tsinde tsinde m'mimba mwake tsinde valavu.Kwa ma valavu ena ozungulira ndi ma valve osabwerera, ngakhale musaganizire tsinde la tsinde kupyolera mu vutoli, koma posankha ayeneranso kuganizira mozama tsinde lake ndi kukula kwa keyway, kuti msonkhanowo ugwire ntchito bwino.

5.5 Kuthamanga Kwambiri: Vavu yotsegula ndi kutseka liwiro ngati mofulumira kwambiri, zosavuta kupanga madzi nyundo chodabwitsa.Choncho, ziyenera kukhazikitsidwa pazikhalidwe zosiyanasiyana za ntchito, kusankha koyenera kutsegula ndi kutseka liwiro.
