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

1.Chimiro chakazara che hydraulic excavator yakazara

MaHydraulic excavator anonyanya kushandisa kaviri pombi yedunhu inoramba iine simba rinochinja hydraulic system, mazhinji ayo anoshandisa anogara aripo simba regulator kudzora maviri hydraulic pombi, uye ese anoshanda masisitimu akakamurwa kuita mapoka maviri (ona pazasi mepu)
Manual mechanical operation valve kana pilot system control operation valve kuti ipedze basa. Mukuwedzera, mubhakiti tsvimbo, bhakiti, boom kushanda, kuitira kuti uvandudze kukurumidza kwemapombi maviri akasanganiswa kuyerera.
2 .Fault diagnosis sequence

Kurongeka kwekukanganisa kuongororwa kweanochera hydraulic transmission system ndeiyi: nzwisisa mamiriro ekushanda emidziyo isati yasvika uye mushure mekukanganisa Kuongorora kwekunze - kuongororwa kwebvunzo (kukanganisa chiitiko, pane-bhodhi chiridzwa) - yemukati system yekuongorora.
(Tarisa kune system schematic diagram) Instrument inspection system parameters (kuyerera, tembiricha, nezvimwewo) kuongorora zvine musoro, kutonga, kugadzirisa, disassembly, kugadzirisa bvunzo - kukanganisa pfupiso rekodhi.
Kune akawanda marudzi ezvikanganiso zvekuchera, zvinoenderana nehunhu hweakasiyana mamodheru, shandisa zvizere zvemidziyo yekutarisa sisitimu, yakananga dambudziko rekuongorora, nyanzvi inoshanda yekuongorora kukanganisa nzira, uye enzanisa iyo hydraulic system.
Zvinoenderana neiyo musimboti dhizaini, iyo yakazara mafuta dunhu yakakamurwa kuita matavi akati wandei zvichienderana nebasa rebasa, zvinoenderana nechakaipa chiitiko, tevera kurongeka kubva kunze kuenda mukati, kubva nyore kusvika kune yakaoma, uye usabvisa bazi rimwe nerimwe. Muchiitiko chekunyanya kuoma synthesis
Kutadza, kunofanira kunyatsoongorora kukanganisa chiitiko, nyora zvinogona kukonzera imwe neimwe kubvisa.
