力士乐REXROTH方向比例阀上海供应

力士乐REXROTH方向比例阀上海供应，力士乐方向比例阀运行原理：
德国REXROTH力士乐比例阀当左侧受力大于右侧受力与感载弹簧预紧力之和时（此时的压力为Ps）,活塞不断右移,Z后使阀门与阀座接触而关闭,将输入输出油路隔绝,达到平衡状态。P1若进一步升高时,则活塞左移,阀门再度打开,制动液流入出油口,使P2也升高。Rexroth比例阀VT-NE30-2X的输入压力为零 即 ;时,输出腔的压力通过

，力士乐方向比例阀运行原理：
德国REXROTH力士乐比例阀当左侧受力大于右侧受力与感载弹簧预紧力之和时(此时的压力为Ps),活塞不断右移,zui后使阀门与阀座接触而关闭,将输入输出油路隔绝,达到平衡状态。P1若进一步升高时,则活塞左移,阀门再度打开,制动液流入出油口,使P2也升高。Rexroth比例阀VT-NE30-2X的输入压力为零 即 ;时,输出腔的压力通过比例阀皮圈凸筋间空酸从唇口泄去高压,同时,当比例阀芯所受的弹簧力大于向右的液压力时,比例阀弹簧将比例阀芯推回原始位置,使比例阀芯与比例阀皮圈内孔*分离而*泄压 此时输入输出压力为零 随着输入压力 增大,即左增大,使比例滑阀单向力平衡遭破坏 当<>&;6-时,比例阀芯左移与比例阀皮圈产生间隙形成节流并混合比倒阀常见的故障为:1,输入输出压力同步 2,低压时辅人输出压力同步,高压时输入输出压力正常 3,低压时输入输出压力正常,高压时输入输出压力不正常 ,1994 №为零时为混合比倒圉工作性能试验，试验时,先将管内的空气排净,然后分别取低,中,高三个压力进行试验,输入辅出压力符合即为合格。
