Ama-actuator kagesi ahlukaniswe izinhlobo ezimbili: kagesi kanye ne-pneumatic. Abantu abaningi bangabuza ukuthi yini umehluko phakathi kwabo nokuthi bahlukanise kanjani? Namuhla, ake sikhulume ngezici kanye nokusetshenziswa kwemishini ye-pneumatic ne-electromechanical.
Ama-actuator kagesi ayaziwa nangokuthi ama-actuator kagesi. Ngokusho kwemodi yokunyakaza, ihlukaniswe: ukuhlelwa kwe-angular stroke kanye ne-stroke eqondile; i-valve yokulawula kagesi noma i-valve butterfly kagesi evame ukusetshenziswa ezinhlotsheni zama-valve zezinsiza ezisekelayo; I-AC eshintshashintshayo yamanje noma i-DC direct voltage ingamandla okushayela; ngokwendlela yokuma, ingahlukaniswa izigaba ezimbili; inzuzo amandla kagesi Elula, isivinini sokudlulisa isignali yedatha esheshayo, ibanga elide lokudlulisela, lilungele uhlelo lokulawula oluphakathi nendawo, ukuzwela okuphezulu, ukunemba okuphezulu, okulula ngephaneli yensimbi yokulungisa kagesi, umhlangano olula kanye nezintambo. Ububi ukuthi isakhiwo sinzima, amandla okushayela mancane, futhi isilinganiso sokuhluleka kwemishini siphezulu kunesama-actuator womoya. Ilungele izindawo ezinezidingo eziphansi zokuvikela ukuqhuma kanye nokuntuleka kwamavalvu womoya.
I-actuator kagesi womoya
Njengoba sonke sazi,ama-actuator we-pneumaticziyizigaba zama-actuator. Okulandelayo okuqukethwe okuqondile komehluko phakathi kwama-activator we-pneumatic nama-actuator kagesi. Indlela yokuphatha kanye nendlela yokulungisa ye-actuator yomoya kuhlangene, futhi indlela yokuphatha ihlanganisa uhlobo lwefilimu yepulasitiki, uhlobo lomshini we-piston, uhlobo lwemfoloko kanye nohlobo lwe-rack. Injini ye-piston ine-stroke ende futhi ifanele izindawo lapho amandla okushayela emakhulu; uhlobo lwe-diaphragm lune-stroke encane futhi lungasunduza kuphela isihlalo se-valve ngokushesha. I-Fork-type pneumatic actuator ine-torque enkulu nesikhala esincane. Ijika le-torque lifana kakhulu ne-valve yesango, kodwa alilihle kakhulu; evamile emizimbeni ye-valve ye-torque ephezulu. I-rack pneumatic actuator inezinzuzo zesakhiwo esilula, ukuma okuzinzile nokuthembekile, ukuphepha nobufakazi bokuqhuma. Uma kuqhathaniswa nama-actuator kagesi, ama-pneumatic actuators
1. Mayelana nokusebenza kobuchwepheshe, izinzuzo zama-actuator womoya ikakhulukazi zihlanganisa izici ezine ezilandelayo:
(1) Ukuzivumelanisa nezimo ezinhle endaweni yokusebenza, ikakhulukazi ukuvutha okuhle. Iyavutha futhi iyaqhuma. Uthuli oluningi. Ozibuthe abanamandla. Uma kuqhathaniswa nomshini wokunyathelisa we-hydraulic ezindaweni zokusebenza ezinzima njengemithombo yemisebe nokudlidliza, izinto zikagesi. Superior Electrical Control System.
(2) Isenzo esisheshayo nokusabela okusheshayo.
(3) Umthwalo mkhulu futhi ungahlangabezana nokusetshenziswa kokuphuma kwe-torque ephezulu (kodwa i-actuator yamanje kagesi ifinyelele kancane kancane izinga lomthwalo we-pneumatic esigabeni samanje).
(4) I-motor yonakaliswa kalula lapho ukuhlelwa kwe-stroke kuvinjiwe noma isihlalo se-valve sivinjiwe.
2. Izinzuzo zama-actuator kagesi ikakhulukazi zihlanganisa:
(1) Asikho isidingo sokuhlanganisa nokuvikela amapayipi omoya ahlukahlukene.
(2) Umthwalo ungaqinisekiswa ngaphandle kwamandla okushayela, kuyilapho i-actuator ye-pneumatic kufanele inikeze ngokuqhubekayo ingcindezi yokusebenza.
(3) Ukuminyana koketshezi lwegesi ngaphandle "kokuvuza" kwe-actuator kagesi kwenza ukuthembeka kwe-actuator yomoya kube buthaka kancane.
(4) Ukwakheka okuhlangene nomthamo omkhulu. Uma kuqhathaniswa ne-actuator ye-pneumatic kagesi, ukwakheka kwe-actuator kagesi kulula. Isistimu yokulawula ye-elekthronikhi eyinhloko iqukethe ama-actuator kagesi kanye nokushintshwa kwamandla kwe-DPDT enezingxenye ezintathu. I-circuit breaker ukuze kufakwe kalula nezinye izintambo.
(5) Umthombo womshayeli we-actuator kagesi uvumelana nezimo kakhulu, futhi ugesi ojwayelekile wemoto ungahlangabezana nezimfuneko, kuyilapho isixhumi somoya kufanele sibe nevalvu yomoya futhi sinciphise idivayisi yokushayela.
(6) I-activator kagesi ithule kakhudlwana ngoba ayikho enye impahla yokusebenza yokucindezela. Ngokuvamile, uma i-actuator kagesi ye-pneumatic ifakwe nge-muffler ngaphansi kwesisekelo somthwalo omkhulu.
(7) Emishinini ye-pneumatic, isignali kufanele iguqulwe ibe isignali yedatha yegesi, bese ibe isignali. Isivinini sokudlulisa sihamba kancane. Amasekhethi okulawula ayinkimbinkimbi awafanele amaleveli ezingxenye ezeqile.
(8) I-actuator kagesi ingcono ekulawuleni ukunemba.
I-actuator kagesi inokuphepha okungalungile kanye nekhono lokuvimbela ukuqhuma, ukuma kwemoto akusheshi ngokwanele, futhi injini yonakaliswa kalula lapho ihlangabezana nokumelana ngesikhathi sokushaywa noma isihlalo se-valve siboshiwe. Kodwa-ke, njengoba i-actuator kagesi ngokwayo inomsebenzi we-servo motor, akukho amplifier yangaphandle ye-servo edingekayo; imojula yokuvikela i-overvoltage ingasetshenziswa; ukuma kwangaphambili nangemuva kukhethwa ngokungahleliwe; i-valve yesango ivaliwe ngemva kokucisha amandla; ezilimele. Ama-actuator kagesi ayaqhubeka nokwenza ngcono futhi andise umkhuba wokuthuthukisa wezinhlelo zokusebenza.
