⒈逆流閥阻尼孔被堵死,，閥座損壞,，繃簧疲勞或損壞,，閥芯移動(dòng)不靈活,，長(zhǎng)途調(diào)壓管路過(guò)長(zhǎng)，發(fā)生嘯叫聲,；避免和掃除辦法是：清洗,，修正，替換繃簧清洗,、去毛刺,，在滿足運(yùn)用要求情況下，盡量縮短該管路長(zhǎng)度,。

       ⒉電液閥電磁鐵失靈,，操控壓力不穩(wěn)定；避免和掃除辦法是：檢修,，選用適宜的操控油路,。

       ⒊液壓油泵內(nèi)部零件卡阻或損壞，軸頸油封損壞,，進(jìn)油口密封圈損壞,；避免和掃除辦法是：清洗,、替換。

       ⒋液壓設(shè)備系統(tǒng)的液壓管路中液壓脈動(dòng),，管長(zhǎng)及元件裝置位置匹配不合理,，吸油過(guò)濾器堵塞，吸油管路漏氣,，油溫過(guò)高或過(guò)低,，管夾松動(dòng)等原因；避免和掃除辦法是：在液壓油泵出口增設(shè)蓄能器或消聲器,，合理確認(rèn)管長(zhǎng)及元件裝置位置,，清洗或替換，改善密封性,，查看溫控組件工作狀況,，緊固等。
