力士乐比例阀4WRPEH6C4B12L-2X/G24K0/B5M参数
力士乐比例阀的工作原理如下：在不制动时,活塞在感载弹簧通过杠杆施加的推力F的作用下,处 于左端极限位置,这时阀门离开阀座打开,使输入输出油路相通。当开始制动时,来自助力器的压力为P1的制动液由进油口进入,并通过阀门从出油口输至后制动管路.此时输出液压P,等于输入液压P1当制动踏板力增大时,P1和P2同步增大。但由于活塞左侧承压面积大于右侧,致使活塞左侧受到的力也大于右侧. Rexroth力士乐比例阀的结构和其它参数一定的情况下,调节作用的初始控制压力P·的值取决于感载的比例阀感载弹簧预紧力的大小,其变化范围在.
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。德国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.,为零时为混合比倒圉工作性能试验示意图.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。
