Wofukula John Deere 200-6210 wogawa ma hydraulic proportional solenoid valve

     Pampu yayikulu ya valve hydraulic pump ikupereka mafuta nthawi zonse, koma kuthamanga kwa hydraulic kukakwera kwambiri, kumayambitsa kuwonongeka. Choncho, dera la hydraulic lili ndi valavu yowonongeka kuti iteteze kuwonongeka kwa mpope. Silinda ya hydraulic imakulitsidwa motalika kwambiri, kapena yayifupi kwambiri, kapena silinda ya hydraulic ndi hydraulic motor imawonjezera mphamvu zambiri, kotero kuti silinda ya hydraulic ndi hydraulic motor stop, mafuta otumizidwa ndi hydraulic pump sangachoke, kotero kuti chipangizo cha hydraulic chikhoza kuphulika, kuthamanga kwa hydraulic kumakwera kwambiri, ndipo pampu ndi yolemetsa kwambiri. Izi zidzabweretsa kuwonongeka kwa mpope, kuti mphamvu ya hydraulic iwonjezere kufika pamlingo wina, mafuta ochokera pampopu adzabwerera ku tanki yamafuta ogwirira ntchito, ndikofunikira kukhazikitsa njira yodutsa, kuti kuthamanga kwa hydraulic kusakhale. kukwera kwambiri. Panthawi imodzimodziyo, kuthamanga kwa mpumulo wa valve yothandizira kungasinthidwenso kuti mudziwe kuchuluka kwa kg / cm2 komwe kumaloledwa kukwera. Valve yothandizira ndi ntchito yomwe yafotokozedwa pamwambapa ndipo imayikidwa mu dera pakati pa pampu ya hydraulic ndi valve yolamulira, koma nthawi zambiri imayikidwa pamodzi ndi valve yolamulira. Ngati chikhalidwe cha valve yothandizira sichili bwino, kutsika kochepa kumatseguka, ndiye kuti kuthamanga kwa hydraulic sikudzapitirira, ndipo mphamvu ya hydraulic cylinder ndi hydraulic motor idzakhala yofooka. Kuonjezera apo, ngati valve yothandizira siili yokhudzana, pamene kupanikizika kumakwera, kumayambitsa kutaya kwa mafuta, ndipo potsiriza mafuta a pampu ndi kutuluka kwa mafuta ali ofanana, kuthamanga kwa hydraulic sikungathenso kukwera pamwamba, kotero kuti mphamvu ya silinda ya hydraulic ndi mota ya hydraulic ndi yofooka
