Just how much fluid could be saved if hydraulic system leaks could be completely eliminated? The number is estimated to be in the hundreds of millions of gallons per year. Although this number may seem high at the outset, consider all of the components which use hydraulic fluid, such as sumps, pumping systems, gear cases and hydraulic machines. Approximately 80 percent of oil loss can be attributed to failure of O-rings, fittings, spills, hose breakage and general leakage.
On the list of the most common causes of hydraulic equipment failure, overheating ranks at number two. Unfortunately, the general understanding about how to identify and address overheating issues is all too often misunderstood.
The best way to prevent contaminants from entering any system is to receive and handle lubricants with care until the system is put in service. After this, the challenge shifts to ensuring that as few contaminants as possible enter the system. Contaminant ingression can be limited by modifying slight glasses and breathers. But the shaft seals used are also important.
When lubricant begins leaking from hydraulic equipment, sumps or pumping systems, the chances are that the incorrect hydraulic seals were selected, installed poorly, maintained improperly or the wrong seals are being used for the application at hand.
Water continues to be the worst and most complex contaminant of hydraulic machinery. It is such a problem and for so many reasons that those reasons continue to be researched. Whether on its own or mixed with another substance such as oil, water can cause the abrupt or gradual failure of bearings, and can result in the catastrophic failure of complete hydraulic systems, including gaskets and hydraulic seals.
Among the main chemical contaminants that threaten your hydraulic system, one of the most sinister can be water. Although innocent on its own, when combined with oil, water can cause numerous problems in hydraulics systems on both the physical and chemical levels.
All hydraulic components need replacing at some point in time. And for those machines that are more than a decade old, OEM parts can be difficult to find. This is one reason why so many machine owners choose parts that have been re-engineered. Parts can be had both from OEMs and independent aftermarket suppliers. But are re-engineered components really the best option?
A cylinder’s job to handle guided loads in motion is a crucial one. In H, cylinders have a higher cost up front due to their operation under high amounts of pressure. As such, it only makes sense to ensure that the cylinders in your system operate and maximum force and last as long as possible. You can boost the force of your cylinders as well as extend their life with a few easy tips.
Hydraulic systems often operate in extreme conditions and are exposed to high loads. As well, many systems are expected to retain their optimal performance in extreme conditions. As a result, the filters used are a critical element of a healthy hydraulic system.
