液压油是液压系统的命脉，这种流体在整个液压系统中传播时执行许多不同的功能，包括润滑运动部件并防止腐蚀液压部件。随着时间的流逝，液压油的质量会直接影响液压系统的性能和耐用性。任何损害液压油有效执行其指定职责的能力的事情都可能导致未来的重大机械问题。本文众友重工带来三个可能困扰液压油的问题。
Please be aware of common problems with hydraulic fluids that may be bothering you so that you can correct these problems before they affect the overall health of the hydraulic system.
1) Pollution:
The main problem that can cause serious damage to the performance of the hydraulic system is the contaminated liquid. Air and water are the two most common contaminants that enter the hydraulic oil supply.
Water pollution will make your hydraulic oil appear milky white appearance, and affect the lubricating performance of hydraulic oil. Water in the hydraulic oil may also limit the ability of the hydraulic oil to prevent corrosion.
Air pollution can be equally detrimental to the performance of the hydraulic system. The air makes the hydraulic oil more elastic, so it cannot be compressed properly. Air contaminated hydraulic oil will have a foamy appearance.
If you find signs of air or water contamination in the hydraulic oil, flush the system quickly to avoid lasting damage.
2) Cavitation:
Cavitation is another problem that can affect hydraulic fluids. Although it sounds like a complicated problem, cavitation is actually a simple process.
Cavitation occurs when rapid changes in hydraulic fluid pressure occur. This rapid change results in the formation of bubbles called cavities within the fluid. Whenever these cavities collapse, tiny shockwaves are emitted. Due to exposure to shock waves, metal components close to these collapsed bubbles may suffer severe damage.
If you notice a sudden increase in noise or feel increased vibration during the operation of the hydraulic system, it may be caused by cavitation. You can combat cavitation by reducing the speed of the motor, lowering the temperature of the pump and installing an impeller inducer.
3) Aging:
Over time, the feasibility of hydraulic oil flowing through the system may decrease. As the hydraulic oil ages, it loses the ability to perform the important tasks required to keep the hydraulic system operating normally.
Aging occurs when chemical additives that enhance the performance of hydraulic oil begin to decompose. As the effectiveness of the additive decreases, your hydraulic oil will also fail.
Just buy the required amount of hydraulic oil to fill the system, so you don't have to have excess inventory. This will help you avoid using aging fluids in your system. You should also schedule regular flushing of fluid to remove hydraulic oil from the system, and then aging will affect its efficacy.
You should be careful to maintain your hydraulic equipment to avoid unplanned downtime or production delays. Perform equivalent maintenance on your hydraulic oil. Pollution, cavitation and aging are all problems generated in hydraulic oil, but if not solved in time, it will eventually lead to serious system failure.
