Ama-actuator kagesi kanye ne-pneumatickuma-valve epayipi: Kubonakala sengathi izinhlobo ezimbili zama-actuator zihlukile kakhulu, futhi ukukhetha kudinga ukwenziwa ngokuya ngomthombo wamandla otholakala endaweni yokufaka. Kodwa empeleni lo mbono ubandlulula. Ngaphezu komehluko oyinhloko nosobala, zinezici eziningana ezingavamile ezingacacile.

Ama-actuator kagesi kanye ne-pneumatic yizona zindlela ezimbili zokushayela ezisetshenziswa kakhulu ezinhlelweni zokuzenzakalela. Ngokuvamile, isinqumo sokukhetha se-actuator senziwa esigabeni sokuklama esiyisisekelo, futhi sizosetshenziswa kuze kube sekupheleni komjikelezo wokuphila ngemva kokufakwa.

Lapho bekhetha uhlobo lwamandla lwe-actuator, abantu bavame ukungacabangi ngamapharamitha e-process medium ephayiphini, kodwa banaka kuphela izinto zokubhekisela zangaphakathi zomklami, isimo sokuphakelwa kwamandla, noma ukuthi indawo ingahlinzeka ngegesi eningi elungisiwe.

Kodwa-ke, ngesikhathi sokusebenza, kuvame ukutholakala ukuthi amanye ama-valve adinga ukuhlonyiswa ngama-actuator, noma amapharamitha e-process medium kwamanye ama-valve azoshintsha. Umbuzo-ke uphakama: Ingabe kufanele ngigcine i-actuator yokuqala noma ngiyishintshe nge-actuator ukuze ngithuthukise ukusebenza?

Impilo yesevisi ende

Lesi sihloko sizokwethula futhi siqhathanise izici zokusebenza eziyinhloko zama-actuator kagesi kanye ne-pneumatic.

Ngaphansi kwezimo ezivamile, abakhiqizi bazoqinisekisa imijikelezo yokusebenza eyi-10,000 yama-actuator kagesi kanye nemijikelezo yokusebenza eyi-100,000 yama-actuator omoya. Ngokusobala, ngokwenani lemijikelezo yokusebenza, i-actuator yomoya inokuphila isikhathi eside ngenxa yesakhiwo sayo esilula. Ngaphezu kwalokho, ubuso bokuxhumana kokungqubuzana kwe-actuator yomoya benziwe nge-elastomer noma i-polymer, futhi ama-O-rings agugile kanye nezinto zomhlahlandlela zepulasitiki kulula ukuzishintsha.

Njenge-actuator kagesi, ngokuvamile kuba ne-gearbox yokunciphisa esuka ku-motor iye ku-output shaft. Kunezigiya eziningi ezihlangana ndawonye, ​​ezizoguga ngesikhathi sokusebenza. Kubalulekile futhi ukuqaphela ukuthi asikho isidingo sokushintsha i-grease yokugcoba phakathi nomjikelezo wokuphila wonke we-actuator yomoya.

I-Torque

Enye yezimiso zokusebenza ezibaluleke kakhulu zama-actuator e-pipeline valve yi-torque. I-torque ye-actuator kagesi incike kumklamo (ingxenye eqhubekayo) kanye ne-voltage esetshenziswa ku-stator. I-torque ye-actuator ye-pneumatic incike kumklamo (ingxenye eqhubekayo) kanye nokucindezela komoya okunikezwa ku-actuator ye-pneumatic.

Ngokuvamile, i-torque ye-actuator kudingeka ibe nkulu kune-torque ephezulu ye-valve, noma ibe nkulu kune-torque edingekayo ukuhambisa isici sokuvala. Ekusetshenzisweni kwangempela, i-torque yangempela ye-valve ingaba nkulu kune-torque ephezulu eshiwo uphawu lokuhweba lomenzi, futhi ibe nkulu kune-torque ephezulu ye-actuator. Lokhu ngokungangabazeki kuyisimo esiphuthumayo.

Uma uqhubeka nokusebenzisa i-actuator, ingabangela umonakalo ku-actuator kanye ne-valve. Uma i-torque ye-valve ikhula, injini izoyikhulisa kancane kancane i-torque ize ifinyelele inani lokudonsa (inani lokudonsa). Lokhu kusho ukuthi isakhiwo somshini siyaphoqeleka ukukhipha futhi simelane ne-torque eningi kakhulu ngaphezu kobubanzi bokuklama.

Ukuvikelwa kwe-torque engaphezulu

Ukuze kuvinjelwe ukuthi imishini ingonakali ngaphansi kwezimo ezishiwo ngenhla, i-actuator kagesi ingafakelwa amadivayisi athile akhethekile. Okuvame kakhulu yi-torque switch, engaba ngeyomshini (isimiso esivamile sokusebenza ukuthi igiya le-worm lihamba ngomugqa esimweni se-over-torque); ingaba futhi nge-elekthronikhi (isimiso esivamile ukukala ugesi we-stator, noma umphumela we-Hall.). Lapho i-torque idlula inani eliphakeme eliklanywe, i-torque switch inganqamula i-voltage ye-stator futhi imise i-actuator motor. Asikho isidingo sokuvikelwa kwe-over-torque kuma-actuator e-pneumatic. Uma i-torque esetshenziswa ku-valve idlula umkhawulo ocacisiwe, izakhiwo zomzimba zomoya ocindezelwe zizokwenza i-pneumatic actuator iyeke ukushayela. Ngokungafani nama-actuator kagesi, i-torque yokukhipha yama-actuator e-pneumatic ngeke idlule umkhawulo womklamo. Kungacatshangwa ukuthi uma i-valve yepayipi ifakwe i-actuator ye-pneumatic, ingozi yokwehluleka kwemishini ngenxa ye-torque edlula inani elicacisiwe iyasuswa.

Idizayini engaqhumi

Uma kukhona izimpahla eziyingozi endaweni esetshenziswayo, imishini kagesi ingabangela ukuqhuma. Ngokuphathelene namazinga okuvikela kanye nezindlela zokuvikela endaweni eyingozi, azifakiwe kulesi sihloko ngenxa yokulinganiselwa kwesikhala.

Noma kunjalo, kusadingeka ukugcizelela ukuthi imishini engaqhumi kumele isetshenziswe ezindaweni ezinezinto eziyingozi.

Uma kuqhathaniswa nama-actuator kagesi ajwayelekile ezimboni, ama-actuator kagesi angaqhumi ama-valve epayipi abiza kakhulu futhi ayinkimbinkimbi kakhulu ekwakhiweni kwawo. Ngisho noma i-actuator yomoya isetshenziswa endaweni eyingozi, ayikho ingozi yokuqhuma. Kwama-actuator omoya, umklamo okhethekile wendawo eyingozi nawo ukhawulelwe kuma-positioners, ama-valve e-solenoid kanye nama-switch omkhawulo (Isithombe 1-3). Ngokufanayo, uma i-actuator yomoya ene-accessory engaqhumi isetshenziswa ukusebenzisa i-valve yepayipi, izindleko zizoba ziphansi kakhulu kuneze-actuator kagesi engaqhumi enomsebenzi ofanayo.

Ukubeka Indawo

Ama-actuator omoya anokunye kokushiyeka okubaluleke kakhulu. Lapho i-actuator ifika maphakathi ne-stroke, indawo yokuma iba yinkimbinkimbi kakhulu, okusho ukuthi indawo yokuma kwe-spool ye-valve yokulawula iba nzima kakhulu.

Ngenxa yezici zomzimba zomoya, ukunemba kokubekwa kwama-actuator omoya kuphansi kaningana kunokwama-actuator kagesi. Uma i-actuator kagesi isebenzisa injini yokunyathela, ukunemba kwayo kokubekwa kuphakeme kakhulu kunokwe-actuator yomoya efakwe i-positioner. Lesi sakamuva singasetshenziswa kuphela ezinhlelweni ezingadingi ukunemba kokubekwa okuphezulu noma ukunemba kokulawula. Ama-actuator omoya asetshenziswa kuma-valve epayipi anezici zawo ekwakhiweni kwesakhiwo: zonke izingxenye zohlelo lokulawula zifakwe ebusweni bangaphandle be-actuator, noma ngaphandle kwesakhiwo esiyinhloko. Uma udinga ukushintsha imodi yokusebenza kusuka ekucinyweni uye ekulawulweni, udinga ukufaka i-valve ye-solenoid esikhundleni se-positioner. Njengoba lezi zingxenye ezimbili zifakwe ngaphandle kwe-actuator yomoya, futhi ukwakheka kwendawo yokuhlangana kufana, kulula kakhulu ukususa umsabalalisi bese ufaka i-positioner. Ngamanye amazwi, i-actuator efanayo yomoya ingasetshenziswa kokubili ukuvala nokulawula ngokushintsha izesekeli ezifanele (Isithombe 1-2).
