komatsu Hitachi Caterpillar Kato Kobelco Daewoo hyundai Sumitomo Sanyi Solenoid vavu

Kodi mungadziwe bwanji kuti valavu ya excavator solenoid ndi yabwino kapena yoipa?

1. Dziwani ngati valavu ya solenoid y2 yatsekedwa bwino. Chotsani mapaipi awiri amafuta opita ku valavu ya solenoid y2 pa mota, ndikutseka madoko awiri amafuta kumapeto kwa mota ndi mapulagi awiri, kenako gwiritsani ntchito makina akuluakulu a winch. Ngati ikugwira ntchito bwino, zimasonyeza kuti cholakwika chimachokera ku valavu ya solenoid y2 sinatsekedwe bwino; ngati ikadali yachilendo, muyenera kuyang'ana ziwalo zake.

2. Dziwani ngati pali vuto ndi loko ya hydraulic. Choyamba sinthani masilinda awiri a loko. Ngati sichikugwira ntchito, chotsani loko kuti muyang'ane mosamala. Ngati simungapeze chifukwa, mutha kugwiritsa ntchito loko yokonzedwa kale kuti muyesere kukhazikitsa kuti mudziwe chomwe chachititsa kulephera. . Chifukwa loko ya hydraulic ya winch yothandizira ndi yofanana ndi ya winch yayikulu, loko ya winch yothandizira ikhozanso kubwerekedwa, ndipo njira yosinthira winch yayikulu imodzi ndi imodzi ingagwiritsidwe ntchito kuzindikira mtundu wa loko yayikulu ya winch. Ngati palibe vuto ndi maloko onse awiri, pitani ku cheke chotsatira.

3. Yang'anani momwe mafuta a chizindikiro cha brake amaperekedwera komanso kusweka mwachangu. Zida zobowolera za r-622 ndi r-825 zopangidwa ndi Geotech. Kuyenda kwa mafuta a chizindikiro kumatha kusinthidwa, ndiko kuti, nthawi yomwe winch yayikulu imatulutsira brake ikhoza kusinthidwa. Chifukwa chake, pamitundu iwiri ya zida zobowolera, kuchuluka kwa kuyenda kwa mafuta a chizindikiro kumatha kusinthidwa kudzera mu valavu yowongolera. Ngati makina akadali kugwira ntchito molakwika, yang'anani ngati chitoliro cha mafuta a chizindikiro cha brake chatsekedwa.

4. Ngati ziwalo zowunikirazi zili bwino, mutha kupitiriza kuyang'ana ndikuchotsa brake kuti muwone ngati brake piston ikuyenda bwino mu stroke yogwira ntchito, ndikuikonza kapena kuisintha malinga ndi chifukwa cha kulephera.
