Chosefera cha excavator ndi chida chofunikira kwambiri papaipi yapakatikati yotumizira. Nthawi zambiri imayikidwa kumapeto kwa valve yochepetsera kuthamanga, valve yochepetsera kuthamanga, valve yokhazikika yamadzi kapena zipangizo zina kuti athetse zonyansa mu valve kuti ateteze valve ndi kukumba. kugwiritsa ntchito bwino makina. Chosefera chofukula chimatha kusefa bwino zoipitsa ndi zowononga ndi makulidwe a filimu yamafuta. Uku ndiye kusefa kwakukulu kwa chinthu chosefera cha excavator. Nthawi zambiri imayikidwa mumayendedwe amafuta oponderezedwa ndikubwereranso kuzungulira kwadongosolo. Mlingo wochotsa zinthu zosefera zofukula pa zolimba zoyimitsidwa m'madzi ndizoposa 96%.

Chofukulacho ndi cha dongosolo lamafuta, ndipo chosefera cha chofufutira nthawi zambiri chimakhala chosefera chamafuta a hydraulic. Kutengera ndi ntchito yake ndi zinthu zosefera, zitha kugawidwa m'zinthu zosefera mpweya, zosefera zamakina, zosefera zamadzimadzi ndi zinthu zosefera dizilo. The excavator dizilo fyuluta agawidwa magawo awiri: coarse fyuluta ndi zabwino fyuluta. Zosefera za Excavator zimayikidwa kuti ziteteze zida zogwirira ntchito zamkati monga chassis, matanki amafuta, ndi injini. Zosefera za dizilo zofukula zimateteza injini, ndipo zosefera zofukula nthawi zambiri zimayikidwa injini isanayambe. Zonyansa zamafuta zimalowa kuchokera kunja kapena zimapangidwira mkati. Imafunika kusefedwa mwachisawawa kenako ndikusefedwa bwino ndi chofufutira kuti zisefe bwino zonyansa mumafuta ndikupewa kuwonongeka kwa injini monga zokala kapena dzimbiri. Chosefera mpweya wofukula ndikusefa zonyansa zomwe zili mumlengalenga kupewa kuvala kwa chassis ndi silinda yamafuta yobwera chifukwa cha zonyansa zomwe zili mumlengalenga. Ziribe kanthu kuti ndi mtundu wanji wa fyuluta, iyenera kufufuzidwa ndikusinthidwa pafupipafupi kuti zitsimikizire kuti chofufutiracho chimagwira ntchito bwino.

Chosefera cha chokumba chimagwiritsidwa ntchito kusefa zowononga zomwe zingalowe mu valavu ndi zigawo zina. Yamwani chinyezi. Chifukwa zinthu zosefera zomwe zimagwiritsidwa ntchito muzosefera zimaphatikizira thonje lagalasi, pepala losefera, manja a thonje loluka ndi zinthu zina zosefera, zinthuzi zimakhala ndi ntchito yotsatsa. Thonje lagalasi la fiber limatha kuthyola tinjere ta mafuta ndikulekanitsa madzi, ndipo zida zina zimatha kuyamwa madzi. , yomwe imathandizira pakusefa chinyezi m'mafuta. Ngati chinthu chosefera chofufutira sichingathe kusefa madzi mumafuta, chidzagwiritsidwa ntchito molumikizana ndi gawo la sefa yolekanitsa. Chosefera chofufutira cha fakitale yathu chimatengera zinthu zosefera magalasi ndi mawonekedwe olekanitsa, omwe amakwaniritsa bwino magwiridwe antchito komanso kulimba. Zosefera za Liugong excavator filter element zimatenga pepala losefera la American HV, lomwe lili ndi kusefera kwakukulu, mphamvu yayikulu yosunga fumbi komanso kukana kwakung'ono koyambirira kwa mpweya woyera, womwe ungawonetsetse kuti mpweya wabwino umalowa munjira ndikuteteza injiniyo moyenera.
