Excavator DH55 DH60 proportional solenoid valve main gun relief valve XKBF-00743

1.Mapangidwe onse a hydraulic excavator yonse

Zofukula za hydraulic nthawi zambiri zimagwiritsa ntchito pampu iwiri yosinthasintha mphamvu yamagetsi, yomwe ambiri amagwiritsa ntchito chowongolera mphamvu kuwongolera mapampu awiri a hydraulic, ndipo njira zonse zogwirira ntchito zimagawidwa m'magulu awiri (onani mapu pansipa)
Valavu yogwiritsira ntchito pamanja kapena valavu yoyendetsa makina oyendetsa ndege kuti amalize ntchitoyi. Komanso, mu ndodo ndodo, ndowa, boom ntchito, pofuna kupititsa patsogolo liwiro la mapampu awiri otaya otaya.
2 .Kufufuza zolakwika

Dongosolo la kuzindikira zolakwika za excavator hydraulic transmission system ndi: kumvetsetsa momwe zida zimagwirira ntchito zisanachitike komanso pambuyo pa cholakwika Kuwunika kwakunja - kuwunika koyesa (cholakwika, chida chapa bolodi) - kuyang'anira dongosolo lamkati
(Tawonani dongosolo schematic chithunzi) zida kuyendera dongosolo magawo (kuyenda, kutentha, etc.) kusanthula zomveka, chiweruzo, kusintha, disassembly, kukonza mayeso - cholakwika chidule mbiri.
Pali mitundu yambiri ya zolakwika zofukula, malinga ndi mawonekedwe amitundu yosiyanasiyana, gwiritsani ntchito mokwanira makina owunikira omwe ali ndi zida, kusanthula kwapadera kwazovuta, njira zowunikira zolakwika, ndikufanizira ma hydraulic system.
Malinga ndi chithunzi cha mfundoyi, dera lonse la mafuta limagawidwa m'nthambi zingapo malinga ndi ntchito yogwirira ntchito, malinga ndi vuto, tsatirani dongosolo kuchokera kunja kupita mkati, kuchokera ku zosavuta mpaka zovuta, ndikupatula nthambi imodzi ndi imodzi. Pankhani ya zovuta kaphatikizidwe
Kulephera, ayenera mosamala kusanthula cholakwika chodabwitsa, lembani zomwe zimayambitsa mmodzimmodzi kuchotsa.
