Warning Signs That Your Hydraulic Cylinder May Need Repairs

Hydraulics are mechanical functions that operate via the force of liquid pressure. Hydraulics-based systems produce mechanical movement by pumping liquid through cylinders which move pistons. Hydraulic cylinders are a critical component of hydraulic systems and are used in a wide variety of industries ranging from food and beverage, manufacturing, engineering, to construction. They are the backbone of heavy machinery like loaders, excavators, backhoe booms, blade handlers, skid steer, wheel loader buckets, and many more. The unmatched power of hydraulic cylinders are what makes these seemingly Herculean tasks possible. The market size for hydraulic systems in Australia measured by revenue was $3.3bn in 2022, so it's plain that hydraulics are a critical part of the nation's continuing progress.

Like all hard-working heavy equipment components, regular use leads to wear and tear that can damage the hydraulic cylinder, reducing its efficiency and sometimes causing costly project delays. There are several signs to watch for that warn against significant hydraulic cylinder damage. This is when it is vital to enlist the services of hydraulic repair in Sydney whose expert technicians can deploy their cutting-edge technology to save your project from facing a complete failure by preemptively preventing a breakdown, thus saving your operation from additional repair costs, replacement, and unplanned stoppages.

Here are some of the warning signs to watch for that indicate that your hydraulic cylinder is in need of repairs.

Fluid Leakage - As soon as you spot fluid under the gland, or moisture on the piston rod, it’s best to call in the repairman. There are several possible reasons for leakage, the seals on the cylinder’s piston might have worn out over time and use, and this might be affecting their performance. Or there’s the possibility of some kind of internal damage to the cylinder’s piston or barrel. Carefully check the cylinder to discover the reason behind the fluid leakage. It's best practice to schedule regular fluid tests to see if the hydraulic fluid is contaminated, which occurs due to the mixing of wear and tear particles from pumps, or the accumulation of dirt and debris clogging the filters. This blockage allows fluid to leak past the rods and piston seals into the surrounding areas.

Loud Banging or Knocking Sounds - Hydraulic cylinders shouldn't make loud and unpleasant noises. If you hear sounds like a jackhammer, it's most likely because there are air bubbles inside the hydraulic fluid or cylinder causing a malfunction. When insufficient fluid flows to the hydraulic circuit pressure decreases, causing the fluid to vaporize. When the pressure eventually returns, the cavity collapses, causing a loud knocking sound. If your system begins to produce these kinds of noises, it is time to make repairs.

Eroded and Broken Seals -Hydraulic cylinders are made up of different kinds of seals which prevent fluid leakage and contamination. Too much wear and tear, hot temperatures, improper installation, or fractures can damage the seals leading to complete failure.

In the event of any of the above signs get professional help immediately!
