Magetsi uye pneumatic actuatorskune mavharuvhu epombi: Zvinoratidzika kuti marudzi maviri emagetsi akasiyana, uye sarudzo inoda kuitwa maererano nemagetsi anowanikwa panzvimbo yekuisa.Asi kutaura zvazviri maonero aya ane rusaruro.Mukuwedzera kune misiyano mikuru uye yakajeka, ivo vanewo huwandu hwezvinhu zvisinganyatsooneki zvakasarudzika.

Magetsi uye pneumatic actuators ndiwo maviri anonyanya kushandiswa dhiraivha masisitimu mune otomatiki masisitimu.Kazhinji, sarudzo yekusarudza yeactuator inoitwa mune yekutanga dhizaini nhanho, uye ichashandiswa kusvika pakupera kwehupenyu kutenderera mushure mekuiswa.

Pakusarudza rudzi rwemagetsi eiyo actuator, vanhu kazhinji havatarise maparamendi eiyo process medium mupombi, asi tarisa chete kune zvemukati mareferenzi zvinhu zvemugadziri, mamiriro emagetsi emagetsi, kana kuti saiti inogona kupa yakakura. huwandu hwegasi rakagadzirwa.

Zvisinei, mukati mekushanda, zvinowanzoonekwa kuti mamwe mavharuvhu anoda kuve akashongedzerwa nemagetsi, kana maparameter epakati pekuita mune mamwe mavharuvhu achachinja.Mubvunzo unobva wamuka: Ndinofanira kuchengeta yekutanga actuator here kana kuitsiva neimwe actuator kuti ndivandudze mashandiro?

Hupenyu hurefu hwebasa

Ichi chinyorwa chichasuma uye kuenzanisa hukuru hwekuita maitiro emagetsi uye pneumatic actuators.

Mumamiriro ezvinhu akajairwa, vagadziri vanovimbisa zviuru gumi zvekushanda kwemagetsi emagetsi uye zviuru zana zvemaoirisheni epneumatic actuators.Zviripachena, maererano nehuwandu hwemasevhisi ekushanda, iyo pneumatic actuator ine hupenyu hwakareba nekuda kwechimiro chayo chakareruka.Uye zvakare, iyo friction yekubata kumeso kweiyo pneumatic actuator inogadzirwa ne elastomer kana polymer, uye yakapfekwa O-mhete uye epurasitiki ekutungamira zvinhu zviri nyore kutsiva.

Semagetsi actuator, kazhinji pane yekudzikisa gearbox kubva kumota kuenda kune inobuda shaft.Kune akawanda magiya anobatana nemumwe, ayo anopera panguva yekushanda.Izvo zvakakoshawo kuziva kuti hapana chikonzero chekushandura girisi yekuzora panguva yese yehupenyu kutenderera kweiyo pneumatic actuator.

Torque

Imwe yeanonyanya kukosha maparamita epaipi valve actuators ndeye torque.Iyo torque yemagetsi actuator zvinoenderana nedhizaini (inogara chikamu) uye voltage inoshandiswa kune stator.Iyo torque yepneumatic actuator zvinoenderana nedhizaini (inogara chikamu) uye kudzvanywa kwemhepo inopihwa kune pneumatic actuator.

Kazhinji, torque yeactuator inoda kuva yakakura kudarika torque yepamusoro yevhavha, kana yakakura kudarika torque inodiwa kufambisa chinhu chekuvhara.Mukushandiswa chaiko, iyo torque chaiyo yevhavha inogona kunge yakakura kupfuura iyo yakanyanya torque inotaurwa nemugadziri wechiratidzo, uye zvakare yakakura kupfuura iyo yakanyanya torque yeiyo actuator.Izvi pasina mubvunzo injodzi.

Kana iwe ukaramba uchimhanyisa actuator, inogona kukonzera kukuvadza kune iyo actuator uye vharafu.Kana iyo torque yevhavha ichiwedzera, mota ichawedzera zvishoma nezvishoma torque kusvika yasvika pakudhonza-kunze kukosha (kudhonza-kunze kukosha).Izvi zvinoreva kuti dhizaini chimiro chinomanikidzwa kubuda uye kumira yakawandisa torque kupfuura dhizaini renji.

Pamusoro pekudzivirira torque

Kuti udzivise midziyo kubva pakukuvadzwa pasi pemamiriro ataurwa pamusoro apa, iyo electric actuator inogona kuve yakashongedzerwa nemimwe michina yakakosha.Iyo inonyanya kuzivikanwa ndeye torque switch, iyo inogona kuve mechaniki (yakajairika kushanda musimboti ndeyekuti honye giya rinofamba axially mutsara mumamiriro e-over-torque);inogona zvakare kuve yemagetsi (yakajairika musimboti kuyera iyo stator ikozvino, kana Horo mhedzisiro.).Kana iyo torque ichidarika kukosha kwepamusoro kwakagadzirwa, iyo torque switch inogona kugura voltage ye stator uye kumisa iyo actuator mota.Iko hakuna chikonzero chekudzivirira-torque mune pneumatic actuators.Kana torque yakaiswa kuvharuvhu ichidarika muganhu wakatarwa, zvimiro zvemuviri zvemweya wakamanikidzwa zvinozoita kuti pneumatic actuator irege kutyaira.Kusiyana nemagetsi emagetsi, iyo torque inobuda yepneumatic actuators haipfuure muganho wekugadzira.Zvinogona kutariswa kuti kana pombi yevhavha yakashongedzerwa nepneumatic actuator, njodzi yekutadza kwemidziyo nekuda kweiyo torque inodarika kukosha kwakatarwa inobviswa.

Kuputika-uchapupu hwekugadzira

Kana paine zvinhu zvine njodzi munzvimbo yekushandisa, midziyo yemagetsi inogona kukonzera kuputika.Nezve mazinga ekudzivirira uye nzira dzekudzivirira munzvimbo ine njodzi, hazvina kubatanidzwa muchinyorwa ichi nekuda kwekugumira kwenzvimbo.

Zvakadaro, zvichiri kukosha kusimbisa kuti midziyo isingaputike inofanirwa kushandiswa munzvimbo dzine zvinhu zvine njodzi.

Zvichienzaniswa neyakajairwa maindasitiri emagetsi emagetsi, zvinoputika-zvisina kuputika mavharuvhu epombi zvinodhura uye zvakanyanya kuoma mukugadzira.Kunyangwe iyo pneumatic actuator ichishandiswa munzvimbo ine njodzi, hapana njodzi inogona kuputika.Kune pneumatic actuators, iyo yakakosha dhizaini yenzvimbo ine njodzi zvakare inongogumira kune mapositioners, solenoid mavharuvhu uye muganhu switch (Mufananidzo 1-3).Saizvozvo, kana pneumatic actuator ine chinoputika-chisina kuputika chikashandiswa kushandisa pombi vharafu, mutengo uchave wakaderera zvakanyanya pane weiyo inoputika-inodzivirira magetsi actuator ine basa rimwechete.

Positioning

Pneumatic actuators ine chimwe chezvikanganiso zvakanyanya.Kana iyo actuator inosvika pakati pekurohwa, kuiswa kwacho kunonyanya kuoma, izvo zvinoreva kuti kuiswa kwe spool yevhavha yekudzora kunonyanya kuoma.

Nekuda kwehunhu hwemhepo, kurongeka kweiyo pneumatic actuators yakadzikira kakawanda pane yemagetsi emagetsi.Kana iyo electric actuator ikatora mota inotsika, kurongeka kwayo kwemaodha akati wandei ehukuru hwepamusoro pane iyo pneumatic actuator ine chinzvimbo.Iyo yekupedzisira inogona kushandiswa chete kune masisitimu ayo asingade yakakwirira yekumisikidza kurongeka kana kutonga kurongeka.Pneumatic actuators inoshandiswa mumapipeline mavharuvhu ane maitiro ayo mukugadzirwa kwemaitiro: zvese zvikamu zveiyo control system inoiswa pamusoro pekunze kweiyo actuator, kana kunze kweiyo huru chimiro.Kana iwe uchida kushandura maitiro ekushanda kubva pakudzora, unoda kutsiva solenoid valve nechinzvimbo.Sezvo izvi zvikamu zviviri zvakaiswa kunze kweiyo pneumatic actuator, uye dhizaini yenzvimbo yekubatanidza yakafanana, zviri nyore kubvisa muparadzi uye kuisa chinzvimbo.Mune mamwe mazwi, iyo imwechete pneumatic actuator inogona kushandiswa kune ese kudzima uye kutonga nekutsiva inoenderana accessories (Mufananidzo 1-2).
