Kuisa mapeji ekutanga evhavha yemagetsi mudziyo
Valve yemagetsi actuator
Valve yemagetsi mudziyo chinhu chakakosha chekutyaira kuti uone kure kure chirongwa, otomatiki kudzora uye kure kudzora kwevhavha. Maitiro ayo ekufambisa anogona kudzorwa nekurohwa, torque kana axial thrust. Nekuti vharafu yemagetsi mudziyo unoshanda maitiro uye mashandisiro zvinoenderana nerudzi rwevharuvhu, mudziyo unoshanda zvakatemwa uye chinzvimbo chevharuvhu mupombi kana midziyo.
Mudziyo wemagetsi kazhinji une zvikamu zvinotevera:
** mota inoratidzirwa nekuremerwa kwakasimba, hombe yekutanga torque, diki nguva inertia, nguva pfupi, basa rinopindirana.
Kudzikisira michina yekudzikisa kubuda kwekumhanya kwemota.
Stroke control mechanism yekugadzirisa uye kunyatso kudzora nzvimbo yekuvhura nekuvhara yevhavha.
Torque inodzikamisa nzira yekugadzirisa torque (kana kusundirwa) kune yakafanotemerwa kukosha.
Manual uye magetsi switching mechanism, inopindirana mashandisirwo ekushandisa manyore kana magetsi.
Chiratidzo chekuvhura chinoratidza nzvimbo yevhavha panguva yekuvhura nekuvhara.
Kutanga, sarudza iyo electric actuator zvinoenderana nerudzi rwevharuvhu
1. Angle stroke electric actuator (Angle 360 degrees) inokodzera butterfly valve, valve valve, plug valve, nezvimwewo.
Kutenderera kweiyo shaft yekubuda yemagetsi actuator isingasviki vhiki imwe, kureva, isingasviki 360 madhigirii, kazhinji 90 madhigirii kuona kuvhurika kwevhavha nekuvhara maitiro ekudzora. Iyi mhando yemagetsi actuator yakakamurwa kuita yakananga yekubatanidza mhando uye base crank mhando zvinoenderana neyakasiyana yekuisa interface mode.
A) Yakabatana zvakananga: inoreva iyo fomu yekumisikidza yakanangana yekumisikidza yekubuda shaft yemagetsi actuator uye tsinde yevharuvhu.
B) Base crank type: inoreva chimiro icho chinobuda shaft chakabatana nevharuvhu hunde kuburikidza ne crank.
2. Multi-rotary electric actuator (Angle 360 degrees) inokodzera mavharuvhu emagedhi, globe valves, nezvimwewo.
Iko kutenderera kweiyo inobuda shaft yemagetsi actuator yakakura kupfuura vhiki imwe, ndiko kuti, yakakura kupfuura 360 madhigirii. Iyo inowanzoda inodarika denderedzwa kuti ione kuvhura nekuvhara maitiro ekutonga kwevhavha.
.
Kufamba kweshaft yekubuda kwemagetsi actuator ndiko kufamba kwemutsara, kwete kutenderera.
Vaviri, maererano nekugadzirwa kwemaitiro ekudzora zvinodiwa kuti uone maitiro ekudzora emagetsi actuator
1. Kuchinja rudzi (kuvhura loop control)
Kuchinja magetsi emagetsi kunowanzo ziva kutonga kwevhavha pairi kana kudzima. Ivhavha inenge iri panzvimbo yakazaruka zvakakwana kana munzvimbo yakavharwa zvakakwana. Rudzi urwu rwevharuvhu harudi kunyatso kudzora kuyerera kwepakati.
Izvo zvinonyanya kukosha kutaura kuti switching emagetsi actuators inogona zvakare kukamurwa kuita kupatsanurwa chimiro uye yakasanganiswa chimiro nekuda kweakasiyana maumbirwo mafomu. Izvi zvinofanirwa kutsanangurwa pakusarudza mhando, zvikasadaro zvinowanzoitika mumunda kuisirwa uye kutonga system *** uye zvimwe zvisizvo.
A) Kupatsanura chimiro (chinowanzonzi common type): iyo control unit inoparadzaniswa kubva kune yemagetsi actuator. Iyo electric actuator haigone kudzora valve yakazvimirira, asi inofanirwa kudzorwa neyekunze control unit. Kazhinji, iyo yekunze controller kana control cabinet inoshandiswa kutsigira.
Kukanganisa kwechimiro ichi ndechekuti haina kukodzera kuisirwa kwese kweiyo sisitimu, kuwedzera wiring uye kuisirwa mari, uye kutadza kutadza, kana kutadza kunoitika, haina kukodzera kuongororwa uye kugadzirisa, kudhura-inoshanda haina kunaka. .
B) Yakabatanidzwa chimiro (inowanzo kunzi inosanganisa mhando): iyo control unit uye yemagetsi actuator yakarongedzerwa yakazara, iyo inogona kushandirwa munharaunda pasina yekunze control unit, uye inogona kushandirwa kure chete nekuburitsa ruzivo rwakakodzera rwekutonga.
Zvakanakira chimiro ichi zviri nyore sisitimu kuisirwa kwese, kuderedza wiring uye kuisirwa mari, kuongororwa nyore uye kugadzirisa matambudziko. Nekudaro, izvo zvechinyakare zvakabatanidzwa zvigadziriso zvigadzirwa zvakare zvine akawanda kusakwana, saka akangwara emagetsi actuator anogadzirwa.
2. Inogadziriswa mhando (yakavharwa loop control)
Iyo inogadzirisa yemagetsi actuator haina kungoita basa rekuchinja mhando yakasanganiswa chimiro, asi zvakare inogona kunyatso kudzora vharafu uye kugadzirisa yepakati kuyerera.
A) Kudzora chiratidzo cherudzi (ikozvino, voltage)
Chiratidzo chekudzora cheanomira emagetsi actuator kazhinji ane chiratidzo chazvino (4 ~ 20mA, 0 ~ 10mA) kana chiratidzo chemagetsi (0 ~ 5V, 1 ~ 5V). Mhando uye maparamendi echiratidzo chekutonga anofanira kunge akajeka pakusarudza rudzi.
B) Fomu rekushanda (magetsi parudzi, magetsi akadzimwa mhando)
Iyo yekushanda maitiro eanotonga emagetsi actuator anowanzo yemagetsi akavhurika mhando (inotora kutonga kwe4 ~ 20mA semuenzaniso, iyo yemagetsi yakavhurika mhando inoreva inoenderana 4mA chiratidzo ivhavha padhuze, iyo inoenderana 20mA valve yakavhurika), uye imwe yacho. imhando yemagetsi yekuvhara (kutora kutonga kwe 4-20MA semuenzaniso, iyo yemagetsi yakazaruka rudzi inoreva iyo inoenderana 4mA chiratidzo ivhavha yakazaruka, iyo inoenderana 20mA valve pedyo). Kupfeka-resistant electrode
C) kurasikirwa kwekudzivirira kwechiratidzo
Kurasikirwa kwekudzivirira kwechiratidzo kunoreva kurasikirwa kwechiratidzo chekudzora nekuda kwekukanganisa kwemutsara, iyo electric actuator ichadzora valve yakavhurika uye padyo neyakaiswa kuchengetedza kukosha, iyo yakajairika kuchengetedza kukosha yakazaruka, yakavharwa zvizere, chengeta mu situ mamiriro matatu.
Chetatu, maererano nekushandiswa kwezvakatipoteredza uye kuputika-chiratidzo giredhi kupatsanurwa kwemagetsi zvishandiso
Zvinoenderana nezvinodiwa zvenzvimbo yekushandisa uye kuputika-chiratidzo giredhi, iyo yemagetsi mudziyo wevharuvhu inogona kukamurwa kuita yakajairika mhando, yekunze mhando, flameproof mhando, yekunze flameproof mhando.
Sarudza iyo inobuda torque yemagetsi actuator zvinoenderana ne torque inodiwa nevhavha
Vhuru kuvhura nekuvhara torque inodiwa inotarisisa torque yekubuda kwemagetsi actuator kusarudza sei, kazhinji inoiswa mberi nemushandisi kana nekufananidza mugadziri wevharuvhu, sezvo mugadziri weactuator anongoita basa rekuburitsa torque yemagetsi, yakajairwa kuvhura nekuvhara vharafu. iyo torque inodiwa inotarirwa nehukuru hwevhavhavha yedhayamita uye kumanikidza kwekushanda, asi nekuda kweiyo mugadziri wevhavha inogadzirisa kurongeka, hurongwa hwekusangana, Naizvozvo, torque inodiwa neyakafanana zvirevo zvevhavha inogadzirwa nevagadziri vakasiyana zvakasiyana, kunyangwe kana iri. kutsanangurwa kwakafanana kwemavharuvhu anogadzirwa nemugadziri wevharuvhu mumwechete. Kana iyo actuator yasarudzwa, sarudzo ye torque idiki kwazvo kuti ikonzerese kuvhurika nekuvhara kwevhavha, saka iyo yemagetsi actuator inofanira kusarudza inonzwisisika huwandu hwe torque.
Chechina, sarudzo chaiyo yevhavha yemagetsi mudziyo base:
Kushanda torque: kushanda torque ndiyo huru parameter yevhavha yemagetsi emagetsi, iyo inobuda torque yechigadzirwa chemagetsi inofanira kuva 1.2 ~ 1.5 nguva dzepamusoro torque yekushanda kwevhavha.
Operation thrust: kune maviri makuru magadzirirwo evhavha yemagetsi mudziyo: imwe haina kuisirwa thrust plate, yakananga kubuda torque; Imwe yacho ine thrust disc, iyo inobuda torque kuburikidza neiyo thrust disc stem nati inoshandurwa kuita inobuda.
