Njira yogwirira ntchito ya jekeseni

Pogwira ntchito, jekeseni wa jekeseni wa mpope akhoza kugawidwa m'magawo awiri: jekeseni yoyamba ndi jekeseni wamkulu, komanso akhoza kugawidwa mu jekeseni isanayambe, mapeto a jekeseni, jekeseni wamkulu, mapeto a jekeseni wamkulu ndi chipinda chamafuta chapamwamba Pali njira 5 zopangira mafuta. Nthawi ya jakisoni wamafuta ndi kuchuluka kwa jakisoni wamafuta amawongoleredwa limodzi ndi plunger yothandizira, valavu ya singano yamafuta, valavu yobwereranso yamafuta, valavu yolumikizira singano yamafuta ndi valavu yowongolera ma elekitiroma.
(1) Kubaya jekeseni
Chigawo chowongoka cha kamera chikakhudza mkono wa rocker, makina owongolera zamagetsi amapereka mphamvu ku valavu yowongolera ma elekitiroma, kotero kuti valavu ya singano yamagetsi owongolera amagetsi imasunthira kumanzere, ndikudula njira pakati pa chipinda chamafuta othamanga ndi njira yamafuta otsika, nthawi yomweyo, gawo la mafuta a pampu Pansi pa mkono wa rocker, pulagi imasunthira pansi motsutsana ndi mphamvu zotanuka za kasupe wobwerera wa plunger yamafuta a pampu, kotero kuti kuthamanga kwamafuta mu mkulu-pressure mafuta chipinda amakwera mofulumira. Kuthamanga kwa mafuta kukakwera kufika ku 18MPa, kukwera kwapamwamba komwe kumapangidwa ndi mafuta pamtunda wapakati pa valavu ya singano ya jekeseni kumakhala kwakukulu kuposa mphamvu yowonjezereka ya masika obwerera kwa valavu ya singano, ndi valavu ya singano ya jekeseni. idzakankhidwira mmwamba kuti iyambe kubayidwa.
(2) Kutha kwa jekeseni isanayambe
Pambuyo jekeseni isanayambe, singano ya jekeseni ya mafuta ikupitiriza kusunthira mmwamba. Kamera ikatembenuza 1/3 ya sitiroko ya jekeseni wamafuta, kumapeto kwenikweni kwa jekeseni wa singano yamafuta imalowa m'bowo la jekeseni wa singano, ndipo pamwamba pa singano ya jekeseni wamafuta Mafuta amatha kungothamangira kumalo obwerera masika. valavu ya singano ya jekeseni kudzera mumpata wawung'ono. Mwanjira imeneyi, chotchedwa "hydraulic gasket" chimapangidwa pamwamba pa valavu ya singano ya mafuta, yomwe imalepheretsa valavu ya singano ya mafuta kuti isapitirire kusunthira mmwamba, kotero kuti mafuta asanayambe jekeseni amakhala ochepa. Pamene chopopera chopopera chikupitiriza kutsika pansi, mphamvu ya mafuta mu chipinda cha mafuta othamanga kwambiri ikupitiriza kukwera. Kuthamanga kwa mafuta kukafika pamtengo womwe watchulidwa, pambuyo poti plunger yothandizira imatsika pansi pamagetsi othamanga kwambiri, kuchuluka kwa chipinda chamafuta othamanga kwambiri kumawonjezeka mwadzidzidzi. kumawonjezeka, mphamvu ya mafuta imatsika nthawi yomweyo. Panthawiyi, kukwera pamwamba pa chulucho pakati pa singano ya jekeseni ya mafuta kumachepa moyenerera, ndipo singano ya jekeseni ya mafuta imayambanso pansi pa kubwereza kwa masika a singano ya jekeseni ya mafuta (mphamvu zotanuka zimawonjezeka chifukwa cha kupanikizika chopozera chothandizira), ndipo Mafuta obaya asanabadwe atha.
