1、首先把壓力(li)，流(liu)量值達到最大(da)看壓力(li)表無(wu)任何(he)動作是否有(you)底壓，如果(guo)有(you)請調節(jie)壓力(li)閥于0。

2、再把流(liu)(liu)量(liang)(liang)值(zhi)調節于0啟動任何動作是否有動作，如(ru)果有請調節流(liu)(liu)量(liang)(liang)閥(fa)無動作。以上條件(jian)必須壓(ya)力流(liu)(liu)量(liang)(liang)zui低電(dian)流(liu)(liu)200ma電(dian)流(liu)(liu)800ma。

3、把壓力流量值zui大(da)再調(diao)節(jie)總壓力閥(fa)壓力值到14.5公斤(jin)即可。

Atos比例(li)閥故障排除

①Atos比(bi)(bi)例閥由于插頭(tou)組(zu)件的接線插座〔基座）老化(hua)、接觸不良(liang)以及電磁(ci)鐵引(yin)線脫(tuo)焊(han)等原因(yin)，導致比(bi)(bi)例Atos比(bi)(bi)例閥不能工作（不能通人電流）。

此時可用電表檢測，如發現電阻無限大，可重新將引線焊牢(lao)，修復插(cha)(cha)座并將插(cha)(cha)座插(cha)(cha)牢(lao)。

②Atos比(bi)例閥(fa)(fa)線(xian)(xian)圑(pu)組件的(de)故(gu)障(zhang)有線(xian)(xian)圈(quan)老化、線(xian)(xian)圉燒(shao)毀、線(xian)(xian)圈(quan)內部(bu)斷線(xian)(xian)以及線(xian)(xian)圈(quan)溫升過(guo)大等現象。線(xian)(xian)圈(quan)溫升過(guo)大會造成比(bi)例電磁(ci)鐵的(de)輸出力不(bu)夠(gou)，其余會使比(bi)例電磁(ci)鐵不(bu)能工(gong)作。對(dui)于線(xian)(xian)圈(quan)溫升過(guo)大，可檢(jian)查通(tong)人電流是(shi)否過(guo)大，線(xian)(xian)圈(quan)是(shi)否漆包線(xian)(xian)絕緣不(bu)良，Atos比(bi)例閥(fa)(fa)（方向控制閥(fa)(fa)）閥(fa)(fa)芯是(shi)否因污物卡死等，一(yi)一(yi)査(cha)明(ming)原因并排除之;對(dui)于斷線(xian)(xian)、燒(shao)壞等現象，須更換線(xian)(xian)圑(pu)。DPZO系(xi)列ATOS比(bi)例閥(fa)(fa)怎(zen)樣調節大小

③Atos比(bi)例閥(fa)銜(xian)鐵(tie)組件的故障(zhang)主(zhu)要有銜(xian)鐵(tie)因其與(yu)導(dao)磁套(tao)構成的摩擦副在使用(yong)過程中磨損(sun)，導(dao)致閥(fa)的力滯環(huan)增加。還有推桿(gan)導(dao)桿(gan)與(yu)銜(xian)鐵(tie)不同心，也會引起力滯環(huan)增加，必(bi)須排除之。

④Atos比例(li)閥(fa)因焊接不牢(lao)，或者使(shi)用中在(zai)比例(li)閥(fa)脈(mo)沖壓力的作用下使(shi)導磁套的焊接處(chu)斷(duan)裂，使(shi)比例(li)電磁鐵喪失(shi)功能。

⑤Atos比例閥導(dao)磁套在沖擊壓力(li)下發生變形，以(yi)及導(dao)磁套與(yu)銜鐵構成的(de)摩擦副在使用過程中磨損，導(dao)致(zhi)比例閥出現力(li)滯環增加(jia)的(de)現象(xiang)。

⑥Atos比(bi)例閥放大器有故(gu)障，導致比(bi)例電磁鐵不(bu)工作。此時應(ying)檢(jian)查放大器電路的各種元件情況，消(xiao)除比(bi)例放大器電路故(gu)障。

⑦Atos比例(li)(li)(li)閥放大(da)器和(he)電(dian)(dian)(dian)(dian)(dian)磁鐵之間的(de)連線斷(duan)線或放大(da)器接(jie)線端(duan)子接(jie)線脫開(kai)，使比例(li)(li)(li)電(dian)(dian)(dian)(dian)(dian)磁鐵不工作(zuo)(zuo)。此(ci)(ci)時應更換斷(duan)線，重(zhong)新連接(jie)牢靠意大(da)利阿(a)托(tuo)斯(si)比例(li)(li)(li)閥的(de)工作(zuo)(zuo)原理(li)電(dian)(dian)(dian)(dian)(dian)液(ye)比例(li)(li)(li)閥是閥內比例(li)(li)(li)電(dian)(dian)(dian)(dian)(dian)磁鐵輸入(ru)電(dian)(dian)(dian)(dian)(dian)壓(ya)信號(hao)產(chan)生(sheng)(sheng)相應動作(zuo)(zuo)，使工作(zuo)(zuo)閥閥芯(xin)產(chan)生(sheng)(sheng)位移，閥口尺寸(cun)發生(sheng)(sheng)改變(bian)并以(yi)(yi)(yi)此(ci)(ci)完(wan)成(cheng)與輸入(ru)電(dian)(dian)(dian)(dian)(dian)壓(ya)成(cheng)比例(li)(li)(li)壓(ya)力(li)、流量輸出元件(jian)。閥芯(xin)位移也可(ke)以(yi)(yi)(yi)以(yi)(yi)(yi)機械(xie)、液(ye)壓(ya)或電(dian)(dian)(dian)(dian)(dian)形(xing)式(shi)(shi)進行(xing)反饋。電(dian)(dian)(dian)(dian)(dian)液(ye)比例(li)(li)(li)閥具有(you)形(xing)式(shi)(shi)種類多(duo)樣、容(rong)易組(zu)成(cheng)使用(yong)電(dian)(dian)(dian)(dian)(dian)氣及(ji)(ji)計算機控(kong)(kong)(kong)(kong)制(zhi)各種電(dian)(dian)(dian)(dian)(dian)液(ye)系統、控(kong)(kong)(kong)(kong)制(zhi)精度高、安裝使用(yong)靈活以(yi)(yi)(yi)及(ji)(ji)抗污染能力(li)強(qiang)等(deng)多(duo)方(fang)面優點(dian)，應用(yong)領域日益拓(tuo)寬。近年研發生(sheng)(sheng)產(chan)插裝式(shi)(shi)比例(li)(li)(li)閥和(he)比例(li)(li)(li)多(duo)路閥充分考慮到工程機械(xie)使用(yong)特點(dian)，具有(you)先(xian)導控(kong)(kong)(kong)(kong)制(zhi)、負載(zai)傳(chuan)感和(he)壓(ya)力(li)補償等(deng)功能。它出現對移動式(shi)(shi)液(ye)壓(ya)機械(xie)整(zheng)體技(ji)術水平提升(sheng)具有(you)重(zhong)要意義。特別是電(dian)(dian)(dian)(dian)(dian)控(kong)(kong)(kong)(kong)先(xian)導操作(zuo)(zuo)、無(wu)線遙控(kong)(kong)(kong)(kong)和(he)有(you)線遙控(kong)(kong)(kong)(kong)操作(zuo)(zuo)等(deng)方(fang)面展(zhan)現了其良(liang)好應用(yong)前景。
