⒈逆流阀阻尼孔被堵死，阀座损坏，绷簧疲劳或损坏，阀芯移动不灵活，长途调压管路过长，发生啸叫声；避免和扫除办法是：清洗，修正，替换绷簧清洗、去毛刺，在满足运用要求情况下，尽量缩短该管路长度。
⒉电液阀电磁铁失灵，操控压力不稳定；避免和扫除办法是：检修，选用适宜的操控油路。
⒊液压油泵内部零件卡阻或损坏，轴颈油封损坏，进油口密封圈损坏；避免和扫除办法是：清洗、替换。
⒋液压设备系统的液压管路中液压脉动，管长及元件装置位置匹配不合理，吸油过滤器堵塞，吸油管路漏气，油温过高或过低，管夹松动等原因；避免和扫除办法是：在液压油泵出口增设蓄能器或消声器，合理确认管长及元件装置位置，清洗或替换，改善密封性，查看温控组件工作状况，紧固等。
