Valve Electric Devicechinhu chakakosha chekutyaira kuti uone valve chirongwa chekudzora, otomatiki kudzora uye kure kure.Maitiro ayo ekufambisa anogona kudzorwa nekurohwa, torque kana axial thrust.Nekuti vharafu yemagetsi mudziyo unoshanda maitiro uye mashandisiro zvinoenderana nerudzi rwevharuvhu, magadzirirwo emidziyo uye vharafu mupombi kana nzvimbo yemidziyo.

1. Sarudza Electric Actuator Maererano neValve Type

1.1 Angle Stroke Electric actuator (Angle <360 °) inokodzera butterfly valve, valve valve, plug valve, nezvimwewo.
Electric actuator inobuda shaft kutenderera isingasviki vhiki, iyo isingasviki 360 °, kazhinji 90 ° kuzadzisa kuvhura kwevhavha uye kuvhara maitiro ekudzora.Iyi mhando yemagetsi actuator maererano nekumisikidzwa kweyakasiyana interface yakakamurwa kuita yakananga-yakabatana mhando, base crank type mbiri.

A) Yakananga kubatana: inoreva yemagetsi actuator yekubuda shaft yakabatana yakanangana neiyo valve stem nenzira yekuisa.

B) Base crank type: inoreva kuburitsa shaft kuburikidza ne crank uye stem yekubatanidza fomu.

1.2 Multi-turn electric actuators (Angle> 360 °) yemagedhi mavharuvhu, globe mavharuvhu, etc. vharafu kuvhura uye kuvhara maitiro ekudzora.

.Kufamba kweshaft yekubuda kwemagetsi actuator ine mutsara, kwete kutenderera.

2. Sarudza nzira yekudzora yemagetsi emagetsi maererano nezvinodiwa zvekutonga zvekugadzirwa kwekugadzira

2.1 Switch type (open loop control) switch type electric actuators kazhinji inopa yakavhurika kana yakavharwa kudzora kwevhavha, ingave iri munzvimbo yakazaruka kana yakavharwa zvakazara, mavharuvhu akadaro haadi kutonga kwakaringana kwekuyerera kwe media.Zvinonyanya kukosha kutaura kuti switch yemhando yemagetsi actuator inogona kukamurwa kuita zvikamu zviviri uye yakasanganiswa chimiro nekuda kweakasiyana maumbirwo mafomu.Kusarudzwa kwemhando kunofanirwa kuitwa kune izvi, kana kuti zvinowanzoitika mumunda kuisirwa uye kutonga hurongwa hwekunetsana uye zvimwe zvisingaenderane zviitiko.

A) Split chimiro (inowanzozivikanwa seyakajairika mhando): Iyo control unit inoparadzaniswa kubva kune yemagetsi actuator.Iyo electric actuator haigone kudzora vharuvhu yega, asi inofanirwa kudzorwa neyekuwedzera control unit.Kuipa kwechimiro ichi ndechekuti haina kunaka kuisa iyo yese system, inowedzera wiring uye yekuisa mutengo, uye iri nyore kuoneka mhosva, kana kukanganisa kukaitika, hazvina kunaka kuongorora nekuchengetedza, chiyero chekuita-mutengo. haina kunaka.

B) Yakabatanidzwa chimiro (inowanzo kunzi Monolithic) : Iyo yekudzora unit inosanganiswa nemagetsi actuator uye inogona kushandiswa panzvimbo pasina kunze kwekutonga unit, uye inogona kushandiswa kure chete nekuburitsa ruzivo rwakakodzera rwekutonga.Kubatsira kwechimiro ichi kufambisa iyo yese system yekumisikidza, kuderedza wiring uye kuisa mari, kuongororwa nyore uye kugadzirisa matambudziko.Asi iyo yechinyakare yakabatanidzwa chimiro chigadzirwa chinewo nzvimbo dzakawanda dzisina kukwana, saka yakagadzira yakangwara yemagetsi actuator.

2.2 Inogadziriswa (yakavharwa-loop control) inogadziriswa yemagetsi actuator kwete chete ine basa rekushandura-mhando yakasanganiswa chimiro, asiwo inogona kunyatso kudzora valve uye kugadzirisa kuyerera kwepakati.
A) Kudzora chiratidzo cherudzi (ikozvino, voltage) chiratidzo chekudzora chemagetsi actuator kazhinji ine chiratidzo chazvino (4 ~ 20MA, 0 ~ 10MA) kana chiratidzo chemagetsi (0 ~ 5V, 1 ~ 5V) .

B) Rudzi rwebasa (rudzi rwemagetsi rwakavhurika, rudzi rwemagetsi rwekuvhara) regulation rudzi rwemagetsi actuator work mode kazhinji magetsi akavhurika mhando (4 ~ 20MA control semuenzaniso, magetsi akavhurika mhando ndeye 4MA chiratidzo chinoenderana nevhavha yakavharwa, 20MA inoenderana ne vharafu yakavhurika), imwe mhando yemagetsi yakavharwa mhando (4-20MA control semuenzaniso, magetsi akavhurika mhando ndeye 4MA chiratidzo chinoenderana nevhavha yakavhurika, 20MA inoenderana nevhavha yakavharwa).

C) Kurasikirwa kwekudzivirira kwechiratidzo kunoreva kuti magetsi emagetsi anovhura uye anovhara vheji yekudzora kune yakagadziriswa kuchengetedza kukosha kana chiratidzo chekutonga charasika nekuda kwekukanganisa kwedunhu, nezvimwe.

3. Sarudza torque yakabuda yemagetsi actuator maererano ne torque inodiwa kuvhura uye kuvhara valve.Iyo torque inodiwa kuvhura nekuvhara vharuvhu inosarudza kuti yakawanda sei inobuda torque iyo electric actuator inosarudza, iyo inowanzo kupihwa nemushandisi kana inosarudzwa nemugadziri wevharuvhu Sezvo mugadziri weactuator ariye chete ane mhosva yekubuda kweiyo actuator, torque inodiwa. nokuda kwekuzarura uye kuvhara kwevhavha inotaridzirwa nezvinhu zvakadai sehukuru hwevhavha yevhavha, kushanda kwekushanda, nezvimwewo. Nokudaro, torque inodiwa nevhavha imwechete yezvinyorwa zvakafanana zvinosiyana kubva kune mumwe mugadziri kuenda kune mumwe, kunyange kubva mugadziri wevharuvhu imwechete yezvakatsanangurwa zvakafanana Kana kusarudzwa kweactuator Torque kuri kudiki kwazvo kuchaita kuti yakajairika kuvhura uye kuvhara vharafu, saka yemagetsi actuator inofanira kusarudza inonzwisisika mhando ye torque.

4. Zvinoenderana nekushandiswa kwezvakatipoteredza uye kuputika-chiratidzo giredhi giredhi remagetsi emagetsi zvinoenderana nekushandiswa kwezvakatipoteredza uye kuputika-uchapupu giredhi zvinodiwa, magetsi emagetsi anogona kupatsanurwa mumhando yemhando, yekunze mhando, flameproof mhando, yekunze flameproof mhando. zvichingoenda zvakadaro.

5. Nheyo Yekusarudza Valve Electric Device Zvakarurama:

5.1 Operating Torque: kushanda torque ndiyo inonyanya kukosha parameter yekusarudza valve yemagetsi mudziyo, iyo inobuda torque yemagetsi mudziyo inofanira kunge iri 1.2 ~ 1.5 nguva dzeiyo yakanyanya kushanda Torque yevhavha.

5.2 Operating Thrust: Kune mhando mbiri huru dzevharuvhu actuator: imwe ndeyekuburitsa torque yakananga isina thrust plate, uye imwe yacho ndeyekuva neplate yekurovera ine torque inobuda inoshandurwa kuita inobuda inosundirwa ne stem nut mu thrust plate.

5.3 Output Shaft Rotation Number: vharafu yemagetsi inobuda shaft kutenderera nhamba yenhamba yekutendeuka ine zita rekuti dhayamita yevharuvhu, vharafu stem pitch, nhamba yeshinda, kuverenga maererano m = H / Zs (m ndiyo nhamba yese ye inoshandura kuti mudziyo wemagetsi ugutse, h ndiwo kureba kwekuvhura vharafu, s ndiyo stem drive thread pitch, Z ndiwo musoro weshinda) .

5.4 Stem Diameter: A multi-turn stem stem valve haigoni kuunganidzwa kana iyo yakawanda stem dhayamita inobvumirwa nemagetsi emagetsi isingagoni kudarika nepakati pevhavha yakapiwa.Naizvozvo, mudziyo wemagetsi hollow kubuda shaft dhayamita inofanira kuva yakakura kudarika dzinde dzinde dzinde dhayamita vharafu.Kune mamwe mavharuvhu anotenderera uye asingadzokeri evhavha hunde mavharuvhu, kunyange usingafungi dhayamita yehunde kuburikidza nedambudziko, asi mukusarudza kunofanirawo kunyatsofunga nezvehunde dhayamita uye keyway ukuru, kuitira kuti gungano rishande zvakanaka.

5.5 Output Speed: Vharavha yekuvhura uye kuvhara kumhanya kana yakakurumidza, nyore kugadzira sando yemvura chiitiko.Nokudaro, inofanira kunge yakavakirwa pamamiriro akasiyana-siyana ekushandiswa, kusarudzwa kwekuvhura kwakakodzera uye kuvhara nekukurumidza.
