If you use hydraulic equipment during the course of your workday, you probably know that hydraulic hoses fail—often. Unfortunately, hydraulic hose failure interrupts the workday and destroys productivity. Luckily, some of the common causes for hydraulic hose failure can be avoided. Here are four common causes for hose failure and some simple steps to avoid the problems.
Pressure Surges within the Hoses
When you're operating hydraulic equipment, pressure surges are bound to happen. This is particularly true when your equipment is operating at maximum capacity throughout the day. This happens when too much pressure builds up and the hoses you're using are unable to handle the increase. You can prevent the problem by installing hoses that are capable of withstanding a greater pressure than you usually work with. The upgraded pressure capacity will accommodate the occasional pressure surge, and that will allow you to continue working without malfunctions.
Operating Temperatures of the Hoses
Your hydraulic hoses are designed to accommodate the maximum temperature of the fluids that will be used in the equipment. However, that doesn't mean that the hoses can accommodate those temperatures on a continuous basis. Running your equipment at maximum capacity for extended periods of time will corrupt the hoses and lead to a degradation of the rubber. It will also damage the fittings that are used to attach the hoses to the equipment. You can prevent heat degradation by giving your equipment intermittent cool-down periods throughout the day.
Bend Radius of the Hoses You're Using
Hydraulic hoses have a specific bend radius that they should remain at. Bending your hoses beyond the bend radius can reduce the necessary pressure inside the hoses to below the recommended settings. In addition, flexing—or straightening—the hose beyond its specifications can decrease the life of the hose. To prevent premature wear and tear and to keep pressure at the optimum levels you should avoid over-bending or straightening the hoses.
Chemical Resistance of Your Hoses and Fittings
If you're running chemicals through your equipment, you need to pay attention to the chemical resistance of your hoses and their fittings, such as O-rings and hose covers. While your hoses are designed to resist most cleaning solvents and oils, there may be some that can cause damage. To prevent damage, be sure you familiarize yourself with the safety manuals for your equipment and hoses.
