R210-7 R220-3 Excavator yekuyamura vharafu XJBN-00653 hydraulic valve

Mushure mekunge jekiseni rapinzwa muhumburumbira musoro, iyo yepakati O-mhete mumaO-mhete matatu inopatsanura nzira yemafuta muhumburumbira mumusoro mugero rekupinda nemafuta uye nzira yekudzoka kwemafuta (chikamu chepamusoro ndiyo nzira yekudzoka kwemafuta). Nekuti kudzvinyirirwa kwemafuta emugero wekupinda neoiri kwakakwira kupfuura iyo nzira yekudzoka kweoiri, kana yepakati O-ring yatyorwa, mafuta ari mugero rekupinza mafuta anonyudza mugedhi rekudzoka kwemafuta, nekudaro zvichiwedzera kudzvanywa mumafuta. return passage. Kana kuvharika kwadzimwa, kudzvanywa mugero remafuta ekudzoka kunodzoserwa kune inopinza mafuta mugero, kuitira kuti kudzvanywa kwemafuta pamberi pegomba remajekiseni kurege kuderedzwa nenguva kusvika pamoto kunze kwekumanikidza kwemafuta, zvichikonzera kuti murazvo ubvise matambudziko. . Kuoma kwekukuvara kweO-ring kunosiyana nehurefu uye hupfupi hwenguva yemoto. Mushure mokunge kukanganisa kwaitika, zvakaoma kuziva kuti cylinder yeinjector yepakati yeO-ring yakakuvadzwa, uye zvinodikanwa kuti zvishoma nezvishoma ubudise injector kuti iongororwe kusvikira chikonzero chawanikwa. Paunenge uchitsiva iyo yakakanganisika yeO-ring, iyo O-ring inofanirwa kuiswa nenzira kwayo muinjector groove uye haigone kumonyoroka; Inofanirwa kuve yakafukidzwa nemafuta isati yarodha cylinder musoro; Sezvo jekiseni richibudiswa kunze uye kurodha zvakare, kazhinji, kana pasina chiyero chakachengeteka zvikuru, plunger stroke yejekiseni inofanira kugadziriswa zvakare.
