China Ntchito Yogwira Ntchito Yogwiritsira Ntchito Brake Booster fakitale ndi ogulitsa | Khalani

Chowonjezeramo chotchinga chimagwiritsa ntchito mfundo yoyamwitsa mumlengalenga injini ikamagwira ntchito, zomwe zimapanga zingalowe mbali yoyamba ya chilimbikitso. Poyankha pakakakamizidwe ka kuthamanga kwapanja komwe kumakhala mbali inayo, kusiyanasiyana kumagwiritsidwa ntchito kulimbitsa kukoka kwa mabuleki.

Ngati pangakhale pali kusiyana kwakanthawi pakati pa mbali ziwiri za chifundacho, chifukwa cha gawo lalikulu la chifundacho, kuthekera kwakukulu kumatha kupangidwanso kuti kukankhira chidacho mpaka kumapeto ndi kupanikizika kochepa. Mukamayima braking, makina opangira zingwe amayang'aniranso zingalowe zomwe zimalowetsa cholowacho kuti chifufuzo chisunthire, ndikugwiritsa ntchito ndodo yolumikizira pa diaphragm kuthandiza anthu kupondaponda ndikukankhira chidutswa chonyamula kudzera pachida chophatikizira.

M'boma lomwe silikugwira ntchito, kasupe wobwerera wa ndodo yolamulira valavu imakankhira ndodo yamagetsi yolumikizira kumalo olowera kumanja, ndipo doko lama valavu lili poyera. Kasupe wamagetsi owongolera amapangitsa chikho chowongolera valavu ndi mpando wa valavu wamlengalenga kulumikizana kwambiri, motero kutseka doko lamagetsi.

Pakadali pano, chipinda chopumira cha mpweya ndi chipinda chamagetsi chothandizira chimalumikizidwa ndi njira yamagetsi yamagetsi kudzera pa vacuum gasi chipinda chazitsulo zamthupi la pisitoni kudzera pamitsempha yamagetsi, ndipo amakhala kutali ndi mpweya wakunja. Injini ikayamba, kutulutsa (kuthamanga kwa injini) pochulukitsa injini kumakwera -0.0667mpa (ndiye kuti, kuthamanga kwa mpweya ndi 0.0333mpa, ndipo kusiyana kwakanthawi ndi kuthamanga kwa m'mlengalenga ndi 0.0667mpa ). Pambuyo pake, chopukusira cholumikizira ndi chosungira chipinda chofunsira zidakwera -0.0667mpa, ndipo anali okonzeka kugwira ntchito nthawi iliyonse.

Mukamayimitsa, bopuloyo imapanikizika, ndipo mphamvuyo imakulitsidwa ndi lever ndipo imagwira ndodo yapanja ya valavu yoyang'anira. Choyamba, kasupe wobwezera wa ndodo yamagetsi yamagetsi amaumirizidwa, ndipo ndodo yolamulira valavu ndi mzati wamagetsi umapita patsogolo. Chingwe cholumikizira chikakwera kupita kumalo komwe chikho cha valavu chowongolera chimalumikizana ndi mpando wa valavu, doko lama valavu limatsekedwa. Pakadali pano, zingalowe m'malo olimbikitsira ndi chipinda chogwiritsira ntchito zalekanitsidwa.

Pakadali pano, kutha kwa ndime yamagetsi kumangolumikizana ndi mawonekedwe a disk. Pomwe ndodo yoyendetsera valavu ikupitilira kupita patsogolo, doko lamagetsi lakutseguka lidzatseguka. Pambuyo kusefera kwa mpweya, mpweya wakunja umalowa m'chipinda chogwiritsira ntchito cholumikizira kudzera pa doko lotsegulira mpweya ndi njira yolowera kuchipinda chogwiritsa ntchito, ndipo mphamvu ya servo imapangidwa. Chifukwa chakuti zinthu zomwe zimayankhidwa zimakhala ndi katundu wofanana wofanana ndi omwe ali pamtunda wopanikizika, mphamvu ya servo imakulirakulira molingana (chiŵerengero cha mphamvu ya servo) ndikuwonjezeka pang'onopang'ono kwa mphamvu yolowetsa ya ndodo yamagetsi. Chifukwa cha kuchepa kwa mphamvu zama servo, pomwe mphamvu ya servo ikakwaniritsidwa, ndiye kuti, pomwe chipinda chofunsira sichikhala zero, gulu la servo likhala lokhazikika ndipo silisinthanso. Pakadali pano, mphamvu yolowetsa ndi kutulutsa kwa chilimbikitso chidzawonjezeka ndi kuchuluka komweko; buleki ikathetsedwa, cholumikizira ma valve chowongolera chimangobwerera m'mbuyo ndikuchepa kwa mphamvu yolowetsera. Pomwe mphamvu yolimbikitsira ikafika, doko la valavu litatsegulidwa, zingalowe m'malo cholumikizira ndi chipinda chogwiritsa ntchito cholumikizira, gawo loyeserera la chipinda chofunsira lidzachepa, mphamvu ya servo icheperachepera, ndipo thupi la piston lisunthira kumbuyo . Mwanjira iyi, pamene mphamvu yolowetsera ikucheperachepera, mphamvu ya servo imatsika pang'ono (servo force ratio) mpaka mabuleki atatulutsidwa kwathunthu.
