Amashanyarazi na pneumatikekumiyoboro ya pipine: Birasa nkaho ubwoko bubiri bwimikorere butandukanye cyane, kandi guhitamo bigomba gukorwa ukurikije isoko yingufu ziboneka kurubuga.Ariko mubyukuri iki gitekerezo kibogamye.Usibye itandukaniro nyamukuru kandi rigaragara, bafite numubare utagaragara cyane udasanzwe.

Amashanyarazi na pneumatike nuburyo bubiri bukoreshwa cyane muri sisitemu yo gukoresha.Mubisanzwe, guhitamo ibyemezo bya actuator bifatwa mugice cyibanze cyo gushushanya, kandi bizakoreshwa kugeza igihe ubuzima buzarangirira nyuma yo kwishyiriraho.

Iyo uhisemo ubwoko bwingufu zamashanyarazi, abantu ntibakunze gutekereza ibipimo byuburyo bukoreshwa mumiyoboro, ariko bakitondera gusa ibikoresho byimbere byuwashushanyije, uko amashanyarazi atangwa, cyangwa niba urubuga rushobora gutanga runini ingano ya gaze yateguwe.

Ariko, mugihe cyibikorwa, usanga akenshi usanga indangagaciro zimwe zigomba kuba zifite ibikoresho, cyangwa ibipimo byuburyo bukoreshwa muburyo bumwe bizahinduka.Ikibazo rero kivuka: Nakagombye kugumana umwimerere cyangwa kugisimbuza ikindi gikorwa kugirango tunoze imikorere?

Kuramba kuramba

Iyi ngingo izerekana kandi igereranye ibikorwa byingenzi biranga amashanyarazi na pneumatike.

Mubihe bisanzwe, ababikora bazatanga ingengabihe 10,000 yo gukoresha amashanyarazi hamwe ninshuro 100.000 yo gukora pneumatike.Ikigaragara ni uko ukurikije umubare wibikorwa, pneumatic actuator ifite ubuzima burebure kubera imiterere yoroshye.Byongeye kandi, ubushyamirane bwo guhuza ubuso bwa pneumatic actuator bukozwe muri elastomer cyangwa polymer, kandi O-impeta zambarwa hamwe nibikoresho bya pulasitiki byoroshye gusimbuza.

Nka moteri ikora amashanyarazi, mubusanzwe hariho kugabanya garebox kuva kuri moteri kugera kumasoko asohoka.Hano hari ibikoresho byinshi bihuza hamwe, bizashira mugihe cyo gukora.Twabibutsa kandi ko nta mpamvu yo guhindura amavuta yo kwisiga mugihe cyubuzima bwose bwimikorere ya pneumatike.

Torque

Kimwe mubikorwa byingenzi byingenzi byerekana imiyoboro ya valve ikora ni torque.Umuriro wa moteri ikora amashanyarazi biterwa nigishushanyo (ibice bihoraho) hamwe na voltage ikoreshwa kuri stator.Umuyoboro wa pneumatike uterwa nigishushanyo (ibice bihoraho) hamwe nigitutu cyumuyaga uhabwa pneumatike.

Mubisanzwe, itara rya actuator rigomba kuba rirenze urumuri ntarengwa rwa valve, cyangwa rurenze urumuri rusabwa kugirango rwimure ikintu cyo kuzimya.Mu mikoreshereze nyayo, urumuri nyarwo rwa valve rushobora kuba rurenze urumuri ntarengwa ruvugwa nikirangantego cyakozwe nuwabikoze, kandi rukanaruta urumuri ntarengwa rwimikorere.Nta gushidikanya ko ibi byihutirwa.

Niba ukomeje gukora actuator, birashobora kwangiza kwangiza na valve.Niba itara rya valve ryiyongereye, moteri izagenda yiyongera buhoro buhoro kugeza igeze ku gaciro gakurura (gukuramo).Ibi bivuze ko imiterere yubukanishi ihatirwa gusohoka no kwihanganira umuriro mwinshi urenze igishushanyo mbonera.

Kurinda umuriro

Kugirango wirinde ko ibikoresho byangirika mubihe byavuzwe haruguru, amashanyarazi ashobora kuba afite ibikoresho byihariye.Igikunze kugaragara cyane ni icyerekezo cya torque, gishobora kuba imashini (ihame rusange ryakazi ni uko ibikoresho byinyo bigenda byerekeje umurongo muburyo bwa over-torque);irashobora kandi kuba elegitoronike (ihame rusange ni ugupima stator igezweho, cyangwa ingaruka za Hall.)Iyo itara rirenze agaciro kateganijwe, impinduka ya torque irashobora guhagarika voltage ya stator igahagarika moteri ikora.Ntibikenewe gukingirwa birenze urugero mumashanyarazi.Niba itara ryashyizwe kuri valve rirenze imipaka yagenwe, imiterere yumwuka uhumeka bizatera pneumatic actuator guhagarika gutwara.Bitandukanye n’amashanyarazi, ibisohoka byumuvuduko wa pneumatike ntibishobora kurenga igishushanyo mbonera.Turashobora gutekereza ko niba umuyoboro wumuyoboro ufite ibikoresho bya pneumatike, ibyago byo kunanirwa ibikoresho bitewe numuriro urenze agaciro kavanyweho.

Igishushanyo mbonera

Niba hari ibicuruzwa biteye akaga mubidukikije, ibikoresho byamashanyarazi birashobora gutera guturika.Kubireba urwego rwo kurinda hamwe nuburyo bwo kurinda ibidukikije byangiza, ntabwo biri muriyi ngingo kubera aho bigarukira.

Nubwo bimeze bityo ariko, biracyakenewe gushimangira ko ibikoresho biturika biturika bigomba gukoreshwa mubidukikije bifite ibikoresho byangiza.

Ugereranije n’inganda zisanzwe zikoresha amashanyarazi, amashanyarazi adashobora guturika kumiyoboro ya miyoboro ihenze kandi iragoye mugushushanya.Nubwo pneumatic actuator ikoreshwa ahantu hashobora guteza akaga, ntakibazo gishobora guturika.Kubikorwa bya pneumatike, igishushanyo cyihariye cyibidukikije bishobora guteza akaga nacyo kigarukira gusa kuri posisiyo, indangagaciro za solenoid no guhinduranya imipaka (Ishusho 1-3).Mu buryo nk'ubwo, niba icyuma gikoresha pneumatike gifite ibikoresho bitarinda guturika gikoreshwa mu gukora umuyoboro w’umuyoboro, igiciro kizaba kiri hasi cyane ugereranije n’icyuma gikoresha amashanyarazi kitagira igisasu gifite umurimo umwe.

Umwanya

Indwara ya pneumatike ifite imwe mu nenge zikomeye.Iyo actuator igeze hagati yubwonko, guhagarara biraruhije, bivuze ko guhagarara kumatongo ya valve igenzura bigoye.

Bitewe n'ibiranga umubiri biranga ikirere, imyanya ihamye yimikorere ya pneumatike irikubye inshuro nyinshi ugereranije niy'amashanyarazi.Niba amashanyarazi akoresha moteri ikandagira, aho ihagaze neza ni amabwiriza menshi yubunini burenze ubw'umuvuduko wa pneumatike ufite imyanya.Iyanyuma irashobora gukoreshwa gusa kuri sisitemu idasaba umwanya uhagaze neza cyangwa kugenzura neza.Imikorere ya pneumatike ikoreshwa mumiyoboro ya pipine ifite imiterere yayo muburyo bwububiko: ibice byose bigize sisitemu yo kugenzura byashyizwe hejuru yinyuma ya actuator, cyangwa hanze yimiterere nyamukuru.Niba ukeneye guhindura uburyo bwo gukora buva kuri off kugirango ugenzure, ugomba gusimbuza solenoid valve numwanya uhagaze.Kubera ko ibyo bice byombi byashyizwe hanze yimikorere ya pneumatike, kandi igishushanyo mbonera cyo guhuza ni kimwe, biroroshye cyane gukuraho uwagabanije no gushiraho umwanya.Muyandi magambo, icyuma kimwe gishobora gukoreshwa muguhagarika no kugenzura mugusimbuza ibikoresho bijyanye (Ishusho 1-2).
