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.
Clean hydraulic oil is critical where optimal operation of the system is the goal. But new oil may not even be as clean as you think; in fact, the ISO cleanliness of ‘new’ hydraulic oil is usually 4 code levels below what is considered to be acceptable for most high-performance hydraulic systems!
Whether small or large, the hydraulic equipment you’re responsible for maintaining needs to be filled with the proper grade and type of oil in order for it to last. Multi-grade engine oil is often used for this purpose. But is it the best option for your hydraulic system?
A constant cost of operating any type of hydraulic equipment is the purchase of replacement fluid. And this cost can really add up over time. Although the integrity of hydraulic seals can sometimes be to blame for leakage, the reliability of any hydraulic system is due to more than one factor.
In the early days of fluid power, it was common to repair the broken parts of a machine. In fact, repair was chosen even when the repaired machine didn’t perform the same function as it did originally. Two or more components would be fused, welded or glued together for a repaired or refurbished product.
Accumulator failure is an unfortunate and common occurrence. When accumulators work properly in a circuit, these vital components can last with very little maintenance. Incorrect operating parameters are the most common cause of failure in hydraulic accumulators.
Hydraulics has always been about solving problems. Customers turn to the Industry with specific needs and requests and we provide the solutions. Sometimes those needs may require some pretty sharp innovative thinking on our part and may even lead to some new technological developments. But with our industry becoming increasingly proactive, now might be a good time to take a peek into the future and see just which kind of technological developments we can expect.
In short, the answer to the above question is a resounding “Yes!” Air, when introduced to the wrong places can do a lot of damage to a hydraulic system. There are many ways that air can enter a hydraulic system. Hydraulic oil can contain up to 10% dissolved air by volume. Air can also become trapped inside the system. This is known as free air.
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.
