识别气动液压站异响的原因：

Abnormal noise in pneumatic and hydraulic stations may be caused by a variety of reasons, and the source of abnormal noise needs to be identified. A common cause is the presence of air in the hydraulic system, which produces noise when the air is compressed. In this case, it is necessary to check whether the oil suction line of the hydraulic pump is leaking, or whether there is sufficient oil in the fuel tank to ensure that the oil can flow smoothly and avoid air mixing.

液压泵或马达的轴承磨损也可能导致异响。轴承磨损会使泵或马达在运转时产生异常声音，这时需要检查轴承是否需要更换。液压系统中的阀门卡滞或损坏也可能导致异响，需要检查阀门是否需要清洁或更换。

Another possible cause is oil pollution in the system or improper oil viscosity. Oil pollution can accelerate component wear and tear, while improper viscosity may cause the pump or motor to run smoothly and produce noise. Therefore, it is very important to check and replace the oil regularly.

Check whether the installation of the pneumatic hydraulic station is firm, and loose parts will also produce abnormal noises when running. Ensure that all connectors and fasteners are fastened to reduce noise caused by improper installation.

Take effective measures to solve the noise problem of pneumatic and hydraulic stations：

The noise problem of pneumatic hydraulic stations is a common industrial problem, especially in high-intensity working environments. In order to effectively solve this problem, a detailed analysis of the source of noise is required. Generally, noise may come from hydraulic pumps, valves, pipeline vibration, or friction of mechanical components. For these sources, a variety of measures can be taken to reduce noise.

一种有效的措施是优化液压系统的设计，选择低噪音的液压泵和阀门，并确保这些组件的安装位置合理，以减少共振和振动。使用隔音材料包裹液压站的外壳和管道，可以显著降低噪音传播。对于管道振动问题，可以通过增加支撑点或使用弹性材料来减少振动幅度。

Regular maintenance and inspection of the hydraulic system is also the key to reducing noise. Ensure that all parts are in good working condition and replace worn parts in time to avoid abnormal noise caused by mechanical failures. Through these comprehensive measures, the noise problem of pneumatic and hydraulic stations can be effectively solved and the comfort and safety of the working environment can be improved.
