，在高壓EH油的沖蝕下，滑閥凸肩的銳邊將會(huì)被磨損，進(jìn)步加重伺服閥的泄漏量，汽門的抖動(dòng)幅度也將迸步增大，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號(hào)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號(hào)調(diào)門有輕微的晃動(dòng)現(xiàn)象，臨時(shí)對機(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。所以對于3號(hào)調(diào)節(jié)汽門伺服閥，經(jīng)過段時(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。故障后，將3號(hào)調(diào)節(jié)汽門的伺服閥拆下，送返至上汽廠清洗檢修，檢測結(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)，由重新?lián)Q了新的伺服閥。力士樂REXROTH伺服閥特殊用途的特殊材料。德國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。
