As we continue our series on the replacement and selection of the proper hose for your system, let’s recap the two previous steps. First was the importance of determining the hose I.D. size, which has a direct correlation to the flow velocity and efficiency of your system. We then discussed the effects of both ambient and media temperatures on the service life of a hose and what to consider to maximize that life. While both are essential, for long term dependability and performance of your hose and hydraulic system, you'll want to identify and address unique factors specific to your application.
We touched a little on application in the temperature blog post, especially when looking at the operating environment of your machinery or equipment. As you know, hydraulic hose is used in hundreds, if not thousands, of applications and with so much to consider for each application from environmental conditions, routing requirements and the type of equipment, what is most important to identify?
Let's focus on a few key elements to consider:
- Impulse and duty cycle. For your system, understanding how frequently the hose will be exposed to the full pressure of the application in addition to sudden surges or spikes in pressure.
- The type of steel wire reinforcement is also important, whether it’s braided or spiral. Without getting too technical, spiral steel wire reinforcement is better for high impulse, high duty cycle than braided reinforcement. The trade-off is flexibility. That’s why you see spiral reinforced hose on heavy duty bulldozers. They don’t need as much flexibility as a hose that can handle the extreme impulses.
- The strength of the hose's outer cover to withstand abrasion. Consider options such as a tough cover or super tough cover or looking at protection accessories available such as guards or sleeving.
- Bend radius is important to consider. Will you be installing the hose back into a tight, cramped space? Consider hoses with flexibility and a shorter bend radius for easier routing. (ie.Compact Spiral)
Whatever your application, your local ParkerStore professional is ready to help you select the right hose. Stop in, tell us about your application and let us walk you through the options.
