When you are putting together a hydraulic system there are certain things that must be considered. You have to assess system pressures to ensure that all your selected components are rated for that, as well as internal system temperatures. You also need to ensure that hydraulic hoses are fitted properly to ensure steady operation. Cost is also something that will be taken into consideration. Another component to assess is the external temperatures in which your hydraulic system will operate. With the hot summer months upon us, it is important to ensure that you are properly accommodating for those escalated external temperatures and that you have an understanding of how they may impact your hydraulic equipment, specifically hydraulic hoses.
Thermal exposure can wreak havoc on hoses utilized in hydraulic equipment. This is due to the fact that hot temperatures can cause elastomers and plastics to age. Direct sunlight can also have the same effect. Thus, the polymers utilized in the hydraulic hose cover and inner tube can be at risk, which in turn, puts your hydraulic system operation in jeopardy.
Extreme heat can cause chain rupture, which makes the plastic weaker and more pliable. It can also lead to initial hardening that is then followed by weakening and softening. Another way that heat affects plastics is by degrading properties through molecular linking and chain growth. The important thing to remember is that these phenomena are irreversible and will leave your hydraulic hoses permanently degraded.
Some experts claim that just increasing external temperatures 18 degrees Fahrenheit above the maximum rated temperature can cut the hose life in half. That is why it is important to pay close attention to the external temperatures affecting your hydraulic system. One way to combat this is to inspect hose assemblies frequently for any signs of damage or deterioration. You can also look for hydraulic hoses that are heat-resistant for applications where your assemblies are exposed to extreme external temperatures.
