⒈逆流閥阻尼孔被堵死，閥座損壞，繃簧疲勞或損壞，閥芯移動不靈活，長途調壓管路過長，發生嘯叫聲；避免和掃除辦法是：清洗，修正，替換繃簧清洗、去毛刺，在滿足運用要求情況下，盡量縮短該管路長度。
⒉電液閥電磁鐵失靈，操控壓力不穩定；避免和掃除辦法是：檢修，選用適宜的操控油路。
⒊液壓油泵內部零件卡阻或損壞，軸頸油封損壞，進油口密封圈損壞；避免和掃除辦法是：清洗、替換。
⒋液壓設備系統的液壓管路中液壓脈動，管長及元件裝置位置匹配不合理，吸油過濾器堵塞，吸油管路漏氣，油溫過高或過低，管夾松動等原因；避免和掃除辦法是：在液壓油泵出口增設蓄能器或消聲器，合理確認管長及元件裝置位置，清洗或替換，改善密封性，查看溫控組件工作狀況，緊固等。
