Four Steps to Consider While Repairing Hydraulic Hose Assemblies
A hydraulic pump is the heart of any machine, and the people that run it, its’ soul. In a similar vein, hydraulic hose assemblies may be thought of as the circulatory system of the machinery. Hydraulic hose assemblies and fittings carry pressurized fluids that are critical to a pumps ability to operate properly. When a hydraulic hose leaks, it’s up to the people in charge to quickly find and fix the problem.
Process for repairing hydraulic hoses –
- Step One: Identify the leak source. Hydraulic hoses can be wound in tight spaces and around the rigid corners. These fittings usually cross one another in spaces that are not quite visible. To identify a leak source clearly, you first need to clean and then dry the area where there is a suspected leakage. Once the area is clean, pressurize the entire system and wear safety glasses, watch the area closely to see where the fluid is coming from.
- Step Two: Depressurizethe system. Discharge the pumps and isolate the accumulator, ensure that the fluid won’t spray uncontrollably.
- Step Three: Addressthe problem accordingly. Example; if there is a loose hose nut, where the hose connects to the machinery, simply tighten the nut and re-pressurize the system. If this doesn’t fix the problem, it may be necessary to replace the entire hose.
- Step Four:Unfortunately, hoses that are cracked or worn out cannot be repaired. They must be replaced. For this, you require quick hands and the right tools.
Safety Note: Don’t use hands to feel around the source, as this may potentially cause a severe burn or the injection of hydraulic fluid into your skin.
Detailed Explanation on Hydraulic hose repair
First, remove all the hose clamps that are holding hose at its place. Next, unscrew one hose nut and quickly replace it with a hydraulic cap, while plugging the hose with a hydraulic plug. Then quickly work on the other end.
Before you replace a new hose, it is recommended that you check for any foreign material that could wreak havoc on a hydraulic system. If the hose is dirty, make use of clean compressed air and a foam projectile to clean it. Make sure it doesn’t bend or twist, as this can lead to more problems in the future. It should not rub against any other components.
A leaking hydraulic hose can be a very serious problem. The best way to stop this from happening is to invest in the best products possible, like those available from Seaway Fluid Power.
