Your hydraulic system shuts down, employees can be in danger, damages can potentially occur on the system, and a mess with probable environmental ramifications can come from hydraulic hose failure. Recognizing the signs of impending failure, taking measures to prevent avoidable failures in the future, as well as performing replacements before that failure occurs are very important consideration when it comes to hydraulic hose repair basics.
Basics of Hydraulic Hose
Often at extremely high pressures and speeds, hydraulic hoses are used to transmit fluid through your hydraulic system. Whether it is a hydraulic power unit on an airport runway or the hydraulics that power an excavator at a construction site, they are vital to the proper operation of your hydraulic system.
Primary Use of a Hydraulic Hose
While also protecting them from outside contaminants, hydraulic hoses must contain fluids while they are being transmitted. Hose failure can indicate that the hose no longer able to contain the fluid and/or can no longer prevent outside contaminants from gaining access to the fluid. In addition to performance issues, hose failure can lead to serious damage and expensive repairs to the components within the system.
Signs You Need to Replace Hose
To prevent hose failure is to perform scheduled inspections at least once a month is one the best ways. During such an inspection, there are a few things to look for that point t impending failure and they are listed below.
1) Structural weaknesses in the hose and eventual leaks that start as twisted hose.
2) Hoses that are kinked or crushed as it leads to higher pressures around the kink and localized stresses that can weaken the strength of the hose
3) If the cause is not addressed, hose failure will come from abrasions and cuts along the outer hose cover.
4) Indicated the hydraulic hose assembly needs to be replaced right away if there is corrosion or cracked fitting.
5) Hose’s integrity is weakened by worn spots.
6) Compromised strength of the hose from exposed wires in the hose.
7) Leaks around hose fittings
8) Oil running along the length of the hose
Before they turn into expensive and risks of catastrophic failures, these are all signs that the hoses on your equipment are in need of replacement, and routine inspections reveal these potential issues. To keep point to sudden changes in hose characteristics and can be used to identify hoses that may be aging past their useful life, inspections periodically is ideal.
Undetected Hose Problems
Where most hose failure is obvious, others are less so. Because of the strength of the reinforcement layer, the tube swells inward instead of outward, leaks can cause the hose to swell in some instances. Changes in the velocity and pressure of the fluid flowing through the hose can be due to a reduction in the inner diameter of the tube. The tube can begin to pull apart internally and the end of the hose may blow off eventually. Revealing hidden problems can be found during inspections as well as pressure checks.
