原裝*德國Rexroth力士樂4通伺服閥/力士樂伺服閥價(jià)格
REXROTH4通伺服閥*級(jí)液壓放大的噴嘴磨損或噴嘴部分堵塞;滑閥卡澀;滑閥凸肩的銳邊磨損;EH壓力至左右側(cè)油的縮孔部分堵塞;伺服閥機(jī)械零偏調(diào)整不準(zhǔn)確。這些原因都有可能造成滑閥凸肩不能精確封堵住壓力油的進(jìn)油口和有壓回油的泄油口,，使滑閥發(fā)生往復(fù)動(dòng)作,，油動(dòng)機(jī)下油缸不斷處于進(jìn)油或泄油的過程，隨著伺服閥泄漏量的增加,，伺服卡與伺服閥組成的閉環(huán)系統(tǒng)就會(huì)處于振蕩狀態(tài),，一但閉環(huán)系統(tǒng)出現(xiàn)振蕩，在高壓EH油的沖蝕下,，滑閥凸肩的銳邊將會(huì)被磨損,，進(jìn)一步加重伺服閥的泄漏量，汽門的抖動(dòng)幅度也將迸一步增大,，這種惡性循環(huán)使得油動(dòng)機(jī)的下油缸不停的進(jìn)油和泄油,，調(diào)門也隨之開和關(guān)，zui終引發(fā)調(diào)節(jié)汽門大幅抖動(dòng)的故障,。3調(diào)節(jié)汽門在靜態(tài)調(diào)試階段曾發(fā)現(xiàn)伺服閥機(jī)械零偏有偏差,，機(jī)械零偏使3調(diào)門有輕微的晃動(dòng)現(xiàn)象，臨時(shí)對(duì)機(jī)械零偏進(jìn)行了調(diào)整,，消除了晃動(dòng)現(xiàn)象,，但由于沒有經(jīng)過校驗(yàn)臺(tái)的校驗(yàn)，機(jī)械零偏的調(diào)整精度不高,。所以對(duì)于3調(diào)節(jié)汽門伺服閥,，經(jīng)過一段時(shí)間的使用，其滑閥凸肩的銳邊磨損應(yīng)當(dāng)是比較嚴(yán)重的,。故障處理后,，將3調(diào)節(jié)汽門的伺服閥拆下,，送返至上汽廠清洗檢修，廠家檢測(cè)結(jié)果與我們的判斷是*的,，滑閥凸肩的銳邊已磨損,，無法修復(fù)，由廠家重新更換了新的伺服閥,。力士樂REXROTH伺服閥特殊用途的特殊材料,。德國公司如紅寶石噴嘴擋板材料，以防止體噴嘴飼料造成傷害和擋板,，以減少靜態(tài)和動(dòng)態(tài)性能,，因此，縮短工作生活,。機(jī)械反饋桿球頭也生產(chǎn)紅寶石,，和緩沖，以防止球的小槽之間的磨損,，因此,，失去控制的閥門，并有尖叫聲,。
