Hydraulic Assemblies and Hoses: Keeping the Pressure Alive in Your System

Reading Time: 3 minutes

Hydraulics make heavy loads easier to move.

From lifting huge assemblies to controlling a precision tool, hydraulics are found in countless industries. The hydraulic power comes from internal pressure provided by liquids and their hoses.

Because hydraulic hoses are so critical to any system, they must be inspected, replaced and maintained on a regular basis. Get familiar with hoses and their assemblies so that any abnormal issues are dealt with in a timely manner. When going to get a hose repair at a location like a Parker Store, you’ll need to provide information about your hose to make sure its repaired properly.

Physical wear issues

Every assembly is made up of several, hose layers that protect the overall structure. The tube, reinforcement and cover come together to make a thick and formidable hose for your pressurized needs.

Physical issues will arise over time that require your attention, such as:

  • Visible wear on the exterior surfaces, including chafing
  • Cracking
  • Hardening
  • Kinking

Isolated issues might be repairable, but widespread damage isn’t cost effective as a service option. Replacing the hose might be the best option in these cases.

O-Ring slippage

Hydraulic hoses and assemblies are under extreme pressure. They might be activated for most of the day, which leads to possible breakdowns involving strain. Don’t be surprised if a leak or pressure drop occurs along your system’s lines.

Dozens of o-rings might dot your hydraulic system’s hose connections. They act as simple seals at juncture points. Whether you have manual or automated monitoring of your hydraulics, o-ring slippage can be difficult to pinpoint. Experience and observation will tell you if a seal is compromised.

Check the fitting

The simplest answer is usually the right one, which is a common quote among service professionals. Look for everyday problems that might plague your hydraulics. These scenarios often involve a broken or cracked fitting.

There’s no need to replace the hose in this situation. Replacing or repairing the fitting is an inexpensive endeavor. A machine might be down for several hours during this repair so consider frequent inspections. Tiny cracks along the fittings should be swapped out before they cause major issues.

Considering hose age

Be aware of each hose’s age by documenting its purchase and installation dates. Many factors contribute to hose aging, including:

  • System vibrations
  • Temperature fluctuations
  • Maintenance stress

When a hose doesn’t function as well as it did in the past, consider swapping it out. You might add it to a system with a lower, pressure range. If this scenario isn’t possible, recycling it is an option. Allowing it to remain in the system only leads to maintenance problems in the future.

Visible leaks

If there are any leaks in your hydraulics, the system cannot operate as designed. Leaks equate to low pressure. Any attachments to the system will appear weak or slow. Those leaks are hazards to both people and the environment.

Most leaks require a new hose to be installed. The layered tube has been damaged. Repairing it will only buy you some time. The leak will appear again as pressure builds within the hose.

The kink factor

Don’t allow kinks or twists to occur in your hydraulic system. They may not seem hazardous, but these consequences occur with chronic kinks, such as:

  • Burst seams
  • Liquid explosion
  • Stretching the hoses

As soon as you notice a kink or twist in the hose assembly, rectify the situation. Short-term kinks won’t damage tough hoses. Leave the kink in place for days on end, however, and problems develop. An unexpected break might occur in the line, which leads to extensive downtime and possible injuries.

Working with a qualified repair team

The best way to deal with any maintenance or replacement situations is by working with a hydraulic repair team. At our MFCP Parker Stores, our team can inspect and quote a repair on your hoses, assemblies or entire system. They also perform hose assemblies while you wait. You’ll have accurate information about the system’s efficiency, especially when it comes to updating the components.

Discuss any system dilemmas with the service technicians, including leak issues. The experts can break down the issue so that an offending part or assembly can be isolated. Every hydraulic system must have good balance for optimal operations.

Hydraulic hoses require an experienced hand for their daily care. Reach out to Motion & Flow Control Products, Inc. Expanding your hydraulic knowledge is just as important as keeping up with daily, business tasks.
