Magetsi amagetsi amagawidwa m'mitundu iwiri: magetsi ndi pneumatic. Anthu ambiri angafunse kuti pali kusiyana kotani pakati pawo ndi momwe angawalekanitse? Lero, tiyeni tikambirane za mawonekedwe ndi ntchito za pneumatic ndi electromechanical zida.
Ma actuators amagetsi amadziwikanso kuti ma actuators amagetsi. Malingana ndi kayendetsedwe ka kayendetsedwe kake, imagawidwa kukhala: makonzedwe aang'ono a sitiroko ndi stroke yowongoka; valavu yoyang'anira magetsi kapena valavu yagulugufe yamagetsi yomwe imagwiritsidwa ntchito kwambiri mumitundu ya ma valve othandizira; AC alternating current kapena DC direct voltage ndi mphamvu yoyendetsa; malinga ndi kaimidwe njira, akhoza kugawidwa m'magulu awiri; Ubwino wake ndi mphamvu yamagetsi Yabwino, liwiro lotumizira ma data mwachangu, mtunda wautali wotumizira, wokomera dongosolo lapakati, kukhudzika kwakukulu, kulondola kwambiri, kosavuta ndi gulu la zida zosinthira magetsi, msonkhano wosavuta ndi waya. Choyipa chake ndichakuti kapangidwe kake ndi kovutirapo, mphamvu yoyendetsa ndi yaying'ono, ndipo kuchuluka kwa zida zolephereka ndikwambiri kuposa kwa ma pneumatic actuators. Ndiwoyenera malo omwe ali ndi zofunikira zochepa zoteteza kuphulika komanso kusowa kwa mavavu a pneumatic.
Pneumatic electric actuator
Monga tonse tikudziwa,pneumatic actuatorsndi gulu la actuators. Zotsatirazi ndizomwe zili zenizeni za kusiyana pakati pa makina oyendetsa pneumatic ndi ma actuators amagetsi. Makina oyang'anira ndi makina osinthira a pneumatic actuator ndi ogwirizana, ndipo kasamalidwe kamene kamakhala ndi mtundu wa filimu ya pulasitiki, mtundu wa makina a pistoni, mtundu wa foloko ndi mtundu wa rack. Injini ya pisitoni imakhala ndi sitiroko yayitali ndipo ndiyoyenera malo omwe mphamvu yoyendetsa ndi yayikulu; mtundu wa diaphragm uli ndi sitiroko yaying'ono ndipo imatha kukankhira mpando wa valve nthawi yomweyo. Fork-type pneumatic actuator ili ndi torque yayikulu komanso malo ang'onoang'ono. Mphepete mwa torque ili ngati valve yachipata, koma osati yokongola; zofala m'matupi a valve okwera kwambiri. The rack pneumatic actuator ili ndi ubwino wa mawonekedwe osavuta, okhazikika komanso odalirika, chitetezo ndi kuphulika. Poyerekeza ndi ma actuators amagetsi, ma pneumatic actuators
1. Pankhani ya luso laukadaulo, ubwino wa makina oyendetsa pneumatic makamaka umaphatikizapo mbali zinayi izi:
(1) Kusinthika kwabwino kwa malo ogwirira ntchito, makamaka kuyaka kwabwino. Zoyaka komanso zophulika. Fumbi lambiri. Maginito amphamvu. Poyerekeza ndi makina osindikizira a hydraulic m'malo ovuta kugwira ntchito monga magwero a radiation ndi vibration, zida zamagetsi. Superior Electric Control System.
(2) Kuchitapo kanthu mwachangu komanso kuyankha mwachangu.
(3) Katunduyo ndi wamkulu ndipo amatha kukumana ndi kugwiritsa ntchito ma torque apamwamba (koma chowotcha chamagetsi chapano chafika pang'onopang'ono pamlingo wa pneumatic load pakali pano).
(4) Galimoto imawonongeka mosavuta pamene dongosolo la sitiroko latsekedwa kapena mpando wa valve watsekedwa.
2. Ubwino wa ma actuators amagetsi makamaka ndi awa:
(1) Palibe chifukwa chosonkhanitsira ndi kuteteza mapaipi osiyanasiyana a pneumatic.
(2) Katunduyo akhoza kutsimikiziridwa popanda mphamvu yoyendetsa galimoto, pamene woyendetsa pneumatic ayenera kupitiriza kupereka mphamvu yogwira ntchito.
(3) Kuchulukana kwamadzimadzi kwa gasi popanda "kutayikira" kwa cholumikizira chamagetsi kumapangitsa kudalirika kwa pneumatic actuator kufooka pang'ono.
(4) Kapangidwe kakang'ono ndi kuchuluka kwamphamvu. Poyerekeza ndi pneumatic electric actuator, kapangidwe ka magetsi kamakhala kosavuta. Dongosolo lalikulu lamagetsi lamagetsi limapangidwa ndi ma actuators amagetsi ndi magawo atatu amagetsi a DPDT. A circuit breaker kuti akhazikike mosavuta ndi zingwe zina.
(5) Gwero la dalaivala wamagetsi amagetsi ndi osinthika kwambiri, ndipo magetsi oyendetsa galimoto amatha kukwaniritsa zofunikira, pamene makina oyendetsa pneumatic ayenera kukhala ndi valve pneumatic ndi kuchepetsa chipangizo choyendetsa galimoto.
(6) Choyatsira magetsi chimakhala chopanda phokoso chifukwa palibe zida zina zogwirira ntchito. Ambiri, ngati pneumatic magetsi actuator waikidwa ndi muffler pansi pa maziko a katundu waukulu.
(7) Mu zida za pneumatic, chizindikirocho chiyenera kusinthidwa kukhala chizindikiro cha deta ya gasi, ndiyeno kukhala chizindikiro. Liwiro losamutsa ndilochepa. Mabwalo owongolera ovuta sali oyenera pamilingo yamagulu ambiri.
(8) The actuator magetsi ndi bwino kulamulira molondola.
Makina oyendetsa magetsi ali ndi chitetezo chochepa komanso kuphulika kwa mphamvu, kaimidwe ka galimoto sikuthamanga mokwanira, ndipo galimotoyo imawonongeka mosavuta ikakumana ndi kukana panthawi ya sitiroko kapena mpando wa valve umamangidwa. Komabe, popeza makina opangira magetsi ali ndi ntchito ya servo motor, palibe amplifier yakunja ya servo yomwe imafunikira; gawo lachitetezo cha overvoltage lingagwiritsidwe ntchito; mawonekedwe akutsogolo ndi kumbuyo amasankhidwa mwachisawawa; valve yachipata imatsekedwa pambuyo pozimitsa magetsi; zowonongeka. Ma actuator amagetsi akupitiliza kukonza ndi kukulitsa njira zachitukuko zamapulogalamu.
