Why Are Your Hydraulic Seals Failing?
One of the most common complications with hydraulic equipment is failed seals. When a hydraulic seal fails, it disrupts the pressure in the system and sometimes allows the hydraulic fluid to leak out of the unit. It is important to recognize the most common causes of hydraulic seal failure so that you can reduce the risk of complications with your equipment. Here are some of the reasons why hydraulic seals fail.
Excessive Heat
Most hydraulic seals are temperature-rated so that users know the maximum temperatures that the seal can safely withstand. When the temperature in the system exceeds that safety rating, hydraulic seals may harden. This hardening process eliminates the necessary flexibility for the seal to shift and move with the equipment. When the seal can't flex the way that it needs to, you'll experience leaks and pressure loss.
Pressure Damage
If a hydraulic seal is exposed to excessive pressure beyond what the seal's structure is designed to withstand, you might find that the seal splits as a result. This is typically referred to as a hydraulic seal fracture, and that split can allow hydraulic fluid to seep beyond the seal and may even interfere with the system's proper operation. Left unaddressed, cracked seals may actually start to fall apart, creating debris in the hydraulic system.
Erosion
In some systems, the fluid passing through the seals has corrosive properties. As a result, the seals sustain damage over time. This erodes the seal and eventually causes enough deterioration for the seal to fail completely. You'll need to make sure that the seals you use are designed for the fluids passing through your system to ensure the longest possible lifespan.
Improper Installation
Sometimes, damage to hydraulic seals happens when the seal is installed. Whether it doesn't receive the lubrication that it needs or it is inadvertently punctured when trying to push it into position, this type of damage is completely avoidable. Make sure that you take every possible precaution for proper and safe seal installation to keep your hydraulic system functioning properly. With the risks of wear and tear on hydraulic seals, it's important that you not contribute to that with unnecessary damage.
These are some of the most common reasons for hydraulic seal failures. The more you understand the risks, the easier it is for you to reduce the occurrences, protect your hydraulic seals, and keep your system running the way that it should.
