Tips For Hydraulic Hose Design And Maintenance

February 28, 2023

Choose The Right Hose 

Choosing the right hydraulic hose is critical for your system’s longevity and efficiency. Several factors can influence hose life, including site damage, abrasion, and exposure to heat.  

Be sure to choose a hose with the correct pressure rating and inside diameter. This will keep pressure loss to a minimum and prevent hose damage during heat generation or excessive turbulence. 

• Route hose parallel to machine contours to decrease hard angle bends that restrict flow and strain the hose. 

• Do not exceed a hose’s working pressure ratings because doing so will shorten hose life and pose safety risks. Consult the hose’s engineering specifications and hose overview chart for recommended flow rates. 

• Twisting is a significant stress that can negatively impact the life of any hose. Prevent twisting by using fittings with swivels and paying close attention to the layline when tightening. 

Check The Fittings 

Hydraulic hose fittings are the joints that connect hoses to valves, pumps, motors, cylinders, reservoirs, and other components in a hydraulic system. They help maintain pressure, prevent leaks and when installed correctly, help keep a hydraulic system running safely and efficiently. 

Fittings come in a wide variety of shapes and sizes. They’re typically made of steel or stainless steel and are designed to be reusable or permanent. However, they can be difficult to identify at first glance so the best way to do this is to measure the thread pitch and diameters. When you have the right fitting, the hose should fit tightly. If the fittings are too loose or tight, they can cause leaks and a breakdown in the hose. 

Maintain The Hose 

Hydraulic hoses need to be maintained regularly to ensure they work safely and efficiently. Failure to do so can lead to a significant amount of downtime and cost you money in the long run. During regular inspections, look for external wear and cracks in the hose cover, as well as tight bends and twists. These are often signs of leaks that can cause serious damage to the hose assembly. If you find these signs, it is time to replace the hose. If you are not sure what’s the best way to go about doing this, be sure to reach out to the professionals at Royal Brass Incorporated to help you get the job done!
