识别液压站空气入侵的迹象

液压站空气入侵是一个常见但容易被忽视的问题，可能导致系统性能下降甚至故障。识别空气入侵的迹象对于维护液压系统的正常运行至关重要。液压油中存在气泡是一个明显的迹象，这些气泡通常在油箱或油管中可见。系统压力波动不定，尤其是在启动或运行过程中，可能是空气入侵的结果。

Unstable movement or crawling of hydraulic cylinders is also a common manifestation of air intrusion. When air enters the system, the compressibility of the hydraulic oil increases, resulting in uneven movement of the actuator. Another important sign is the increase in system noise, especially during high-pressure operation, the presence of air can cause abnormal noise in the hydraulic system.

The abnormal increase in the temperature of the hydraulic oil may also be related to air intrusion, because the mixing of air will reduce the cooling effect of the hydraulic oil. By regularly checking these signs, the problem of air intrusion can be detected and solved in a timely manner to ensure the stability and efficiency of the hydraulic system.

Adopt effective methods to eliminate air from the hydraulic system

Removing air from the hydraulic system is a key step to ensure the normal operation of the system. Air entering the hydraulic system may cause noise, reduced efficiency, and even system failure. Here are some effective ways to remove air from the hydraulic system：

确保系统在启动前处于完全充满油液的状态。在启动泵之前，检查所有的油管和接头，确保它们没有泄漏，并且所有的油液都已经正确地填充到系统中。

使用正确的排气程序。在启动泵之后，慢慢地操作系统的各个部分，如阀门和执行器，以帮助空气从系统中逸出。在操作过程中，注意观察油液的流动，确保没有气泡产生。

Next, check the exhaust valve in the system. Make sure that the exhaust valve is open so that the air can be discharged smoothly. If the exhaust valve is clogged or damaged, it should be cleaned or replaced in time.

Regularly inspect and maintain the hydraulic system. Regularly check the cleanliness and oil level of the oil, and replenish or replace the oil in time. This prevents air and other impurities from entering the system, thereby maintaining the efficient operation of the system.
