If you’ve had trouble trying to predict how long your hydraulic pump will last, you’re not alone; the lifespan of any pump can be next to impossible to figure, even with a lot of past experience. Unfortunately, there currently exists no approach that’s dependable enough to reveal a precise figure. However, it isn’t necessary to guess about how long your hydraulic pump will live; all that needs to be done is to look at a few factors.
There are many places in a hydraulic system to place a filter. Unfortunately, no matter where it is located, a filter will reduce component’s service life, even though it will remove contaminants from oil. That being said, when considering the best location for a filter in your system, the first consideration should be to place it in a location where it will do more good than harm.
Although your hydraulic system’s filters are meant to maintain the cleanliness of the fluid that flows through them, there are some filter locations which can actually result in the opposite. The suction line is a common filter location. However, there are many caveats to installing filtration at this point of a system.
The gas-charged accumulators on modern hydraulic systems are an expected element. These components do many things for the system, including controlling leakage, energy recovery, energy reserve and storage and shock absorption. However, these incredibly useful components must be maintained in order to ensure a long service life. As a pressure vessel, the hydraulic accumulator must be inspected, tested and certified. This may be a legal requirement to ensure proper functioning.
In the last post, the function of lip seals was covered, as was how to ensure their proper selection and their features and construction. The conversation about lip seals and their role in contamination control continues in this post.
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.
Anyone in charge of the maintenance of hydraulic equipment needs to pay attention not only to where replacement hoses are sourced from, but also ask questions about how those hoses are stored, cleaned and made before ever installing them on a piece of equipment. The reason that understanding these items is so important is because of how common an occurrence the need for hose replacement is.
The conversion of a hydraulic system to fire-resistant fluids is something that should be considered very carefully. This is because modifications will need to be made before conversion can occur, even when only converting to one fire-resistant fluid from another. As well, each type of fire-resistant fluid has unique characteristics, which can affect even those systems which are already using one type.
Among the many types of hydraulic seals that exist in your system, the lip seal is of particular importance where contamination needs to be controlled. Unfortunately, it is also a component which can require frequent replacement. It can even be the reason that a system needs to be taken out of service due to leaks.
