液压泵发生故障的 5 个原因

液压泵负责保持液压系统的运转。尽管它们已经存在了很长时间，但这些泵作为复杂的机械形式仍然引人注目。

它们的工作是将输送给它们的机械能转化为液压能，但它们如何做到这一点却令人震惊。

液压泵的工作原理

液压泵必须产生足够的流量来克服来自负载的压力。

工作时，液压泵会产生有助于液体移动的真空。真空有助于将液体从泵容器移动到入口管线。泵的持续运动也会导致液体进入泵出口，最终进入液压系统。

液压泵通常分为 3 类，即活塞式、齿轮式和叶片式。

活塞

这些泵最适合在高系统压力下处理大流量。它们通常用于建筑设备、海洋用途、海上设备和钻井，以及各种工业用途。

装备

这些泵整体零件相对较少，工作压力约为 210 bar，通常可以在 3000-6000 rpm 左右的速度下工作。

风向标

这些泵以较低的流量脉动运行，并且通常需要内部液压流体的恒定流量。由于这些条件，叶片泵通常会产生较小的噪音，同时保持高速。

液压泵故障的5个常见原因

液压泵的许多部件需要协调工作才能使整个机器正常工作。考虑到所涉及的组件，不难想象事情会如何开始出错。

以下是液压泵无法正常工作的一些最常见原因。

1. 水污染
   水混入液压油对液压泵来说是个坏消息。 When too much water is present in the hydraulic fluid, the internal components may start to corrode.In addition to its corrosion-causing qualities, water is also problematic because it could freeze inside the pump.
2. Hydraulic Fluid Issues
   The hydraulic fluid present inside the pump can also be problematic even if it doesn’t mix with water.If some small particles fall into the liquid, it’s possible that they could deal damage to the inside of the pump. You must also check if the fluid level is correct or else that could alter the performance of the pump.Lastly, the viscosity of the hydraulic fluid must be just right to keep the pump from sustaining damage. Make it a habit to routinely check the viscosity of the hydraulic pump to see that it has not degraded just yet.
3. High Levels of Heat
   Heat can act as a kind of amplifier of other hydraulic pump-related issues. The heat itself can be a byproduct of other issues affecting the hydraulic pump so be sure to take note of it.
4. Leaks in the Joints and Shafts
   Because hydraulic pumps need the right pressure levels to function, anything that affects it can be disruptive or even damaging. Some of the joints and shafts of hydraulic pumps may spring leaks as they age causing holes to open up. If too much air gets inside the pump via the holes, it may not work as intended.
5. Cavitation
   Cavitation refers to the formation of small vapor-filled bubbles in areas within the pump where the pressure is low. Once those bubbles are exposed to high pressure, they may burst and start to damage the pump.
