Dongosolo la hydraulic of excavator la hydraulic excavator lili ndi zigawo zinayi zazikulu: zida zamphamvu, zida zakupha, zida zowongolera ndi zida zothandizira.
Mphamvu yamagetsi nthawi zambiri imakhala pampu ya pistoni yosinthika, yomwe ntchito yake ndikusintha mphamvu yamakina a injini kukhala mphamvu yamadzimadzi, ndipo kulephera kofala sikukwanira kukakamiza kwamafuta apompo komanso kutsika kwamadzi.Ngati chodabwitsa ichi ndi chapang'onopang'ono, ndipo kutentha kwapamwamba kumakhala koonekera kwambiri, ndi chifukwa cha kuwonongeka kwakukulu ndi kung'ambika kwa pampu ya hydraulic;ngati chodabwitsa ichi mwadzidzidzi, makamaka chifukwa plunger sachiza;ngati kupanikizika kuli koyenera, kuthamanga kumachepa mwadzidzidzi, komwe kumachitika chifukwa cha makina osinthika omwe amamatira pang'ono.
Zinthu zoyendetsera zinthu zimaphatikizapo ma silinda a hydraulic ndi ma hydraulic motors, omwe ntchito yawo ndikutembenuza kukakamiza kwamadzimadzi kukhala mphamvu yamakina, chovuta chodziwika bwino ndikuchepetsa kuchitapo kanthu kapena kusachitapo kanthu.Ngati pampu ndi valavu zimatsimikiziridwa kuti zilibe vuto, chifukwa chakuchita pang'onopang'ono kwa chinthu chothandizira ndi chifukwa cha kuwonongeka kwake kwakukulu;ngati mpope imagwira ntchito bwino, kusuntha pang'onopang'ono kwa chinthu chothandizira kumakhala ndi vuto, monga valavu silinakhazikike, valavu yopumirayo siyimatsekedwa mwamphamvu kapena mphamvu ya masika imafooka, ndi kadi.Chifukwa kuchuluka kwa mavalidwe ndi kung'ambika kwa chinthu chilichonse chautsogoleri sikudzakhala kosiyana kwambiri, monga zifukwa zina, ziyenera kukhala zinthu zingapo zotsogola zomwe nthawi yomweyo zimachedwerapo mwadzidzidzi;ngati zimadziwika kuti pampu ndi valavu sizolakwika, chinthu chachikulu mwadzidzidzi sichichitapo kanthu, makamaka chifukwa cha kugwedezeka kwake mkati.
Zinthu zowongolera zimaphatikizapo ma valavu osiyanasiyana, monga ma valve oyendetsa ndege, ma valve oyendetsa njira zambiri, ma valve akuluakulu otetezera, ma valve otetezera ndi njira imodzi yokha, ndi zina zotero. , makamaka anamamatira, kutsekedwa ndi kasupe elasticity kufooka ndi kutayikira mkati ndi kunja.
Zida zothandizira makamaka zikuphatikizapo thanki ya mafuta, chitoliro cha mafuta, radiator, fyuluta ndi accumulator, ndi zina zotero. etc. Ntchito ya fyuluta ndikusefa zonyansa zosakanizidwa mu mafuta a hydraulic, ndipo zolephera zake zofala zimaphatikizapo kutseka kwa chinsalu.Ntchito ya accumulator ndikukhazikitsa ndikuwongolera kuthamanga kwamafuta ndikusunga mphamvu zina kuti zitsimikizire kuti zikuyenda bwino ndipo injini ikalephera kugwira ntchito, chipangizocho chimatha kutsitsidwa pansi, ndipo zolephera zake wamba ndizosunga mphamvu zosakwanira. zotsatira, sangathe kumaliza ntchito pamwamba.Zothandiza zigawo za kulephera chodabwitsa zambiri zoonekeratu, zosavuta kuzindikira.
