One of the most essential components of almost all modern machinery is the hydraulic hose. The hose is used to connect any two fluid ports that need a flexible link within the machine. The hose is simply a reinforced rubber tube which is encased by a strong cover material, such as a rubber casing. The main reason hoses are inserted between two machine parts is to allow movement between the two ports. The hose is also designed to reduce the effects that vibration may have on the effectiveness of the machine.

Like all other machine parts, the hydraulic hose is prone to wear and tear, especially when used for a long time. Understanding the reason why they fail makes it easier to maintain and repair them.

1. When the Tubes Get Eroded

One of the common indicators that a hydraulic system is failing is when it starts leaking fluid. Fluid leakage is usually as a result of excessive erosion on the walls of the tube. Erosion occurs when high-velocity fluid is forced through the tubes. It can also be the result of the fluid having particles which rub against the walls of the tubes repeatedly. This friction wears down the rubber until weak points, where the fluid escapes through, appear.

The best way to avoid erosion is to buy hose sizes according to the maximum fluid velocity you need it to bear.

2. Incompatibility of the Fluid

Normally, hydraulic hoses are created to handle the different fluids passing through it. However, some fluids may be incompatible with your hose. The common signs that the fluid is harming your hose include swelling, deterioration, and delamination of the inner tubes of the hose.

Note that the tube might be compatible with the fluid, but if parts, such as the outer cover, fittings and O-rings, are not compatible, the system will still fail.

3. Small Bend Radii

There is a minimum bend radius that a hose assembly needs to meet to function properly. If your assembly does not meet this radius, it will fail and, unfortunately, tear down the tube. The tearing happens when the fluid that is moving at high velocity is forced through a restricted passage.

Other reasons why your hydraulic systems may fail include aged air inside the system and improper system assembly. It is advisable to always make sure that you get a professional to help with the purchase and installation of hydraulic systems. Also, call in an expert for inspection and repair when your hose fails. For more information about hydraulic hose repairs, speak with a professional.
