Many of today’s hydraulic systems employ valves of the electro-hydraulic variety. These valves allow for the rapid conversion of electrical energy to mechanical energy. However, they are also of a far more intricate construction than their older control valve counterparts. As such, they tend to be more vulnerable to damage due to solids contamination.
The aeration of fluid in hydraulic systems can cause any number of issues, including cavitation, poor response time and high noise volumes. Bubble removal can address all of these issues and more, as well as lessen the size of the reservoir and lower system costs overall. But how do bubble removal systems work?
The most common culprit for the failure of rod seals in hydraulic systems is damaged piston rod bearings or damaged piston rods themselves. There are many potential but typical causes of this kind of damage. Anything that places the linear force of the cylinder in jeopardy, such as misaligning a cylinder with its load or continuing to use a bent piston rod can place your entire system at risk of failure.
