我的液压设备需要维修的迹象
液压设备无处不在,但我们大多数人都没有注意到它。例如,典型的家用车辆上有多种类型的液压泵、制动器和马达。如果您拥有一艘船,液压系统会帮助它操纵。得益于挖掘机、推土机上的液压元件以及制造工作场所中的大量复杂机械,从建筑工地到机械车间的企业都在高效运行。
现代世界中有如此多的地方依赖液压设备来保持平稳运行,因此我们必须检查和维护这些系统。
知道告诉我们他们有问题的迹象 .忽视液压问题的症状可能会导致设备故障和昂贵的维修甚至完全更换。
为避免潜在的严重问题,请注意以下四种常见的液压系统故障迹象:(1)异常噪音,(2)运行速度降低,(3)工作温度高,以及(4)泄漏。
详情如下:
1。响亮或异常的噪音
液压系统发出的特殊噪音通常是由曝气或气蚀引起的。当空气污染液压油时,会发生曝气并使其降解,从而导致系统组件损坏。
当系统的流体需求超过其供应时,就会发生气蚀,从而导致气泡的形成,从而产生蒸汽腔。有时可以通过减慢流经系统的流体来缓解这种情况。
请记住,任何机器的零件都会磨损并停止最佳性能。每当您听到液压设备发出异常响亮的噪音时,几乎可以肯定它需要维修或更换。
2。运行速度降低
如果您的液压系统速度变慢或循环时间变长,通常表明出现了问题。放缓的罪魁祸首之一是泄漏。您可能知道流量决定了执行器的速度和系统内的响应。因此,速度的损失通常是由流量的损失引起的。
当存在泄漏(外部或内部)时,流体可能会从液压回路中逸出。外部泄漏,例如软管破裂,通常很容易发现和修复。诊断泵、执行器或阀门中的内部泄漏更具挑战性。
3。高流体温度
液压系统需要特定级别的粘度才能正常运行。由于温度是控制粘度的因素之一,因此它需要保持在系统制造商推荐的范围内。高于 180 华氏度(82 摄氏度)的流体温度可能对液压系统的运行有害。
高流体温度会损坏密封件并加速流体的分解。如果系统没有充分冷却,它将承受过度的应变,最终可能导致过早失效。
由于热量通过储液罐散发,因此定期检查和保持正确的液位至关重要。
4。泄漏
如前所述,泄漏会降低系统压力,从而增加工作温度,从而对液压系统产生不利影响。这种增加反过来会影响流体的粘度,从而进一步降低压力。
Once you see liquid on the outside of the pump, the problem has progressed, and you must take action right away since a leak is often a sign of your hydraulic system’s impending doom!

What happens when air gets into a hydraulic system?
Some of the most common effects of air in the system include loss of horsepower, low system fluid, higher temperatures, cavitation (explained above), and spongy control, which means a softer, less stiff response in the system.
How often should you replace hydraulic fluid?
Since hydraulic fluids are an essential ingredient of your system, you must maintain fluid levels and purity within an acceptable range. Check the fluids after the first 100 hours of operation. It’s best to replace them every 1000 hours after that, or as recommended by the manufacturer.
