Hydraulic Cylinder Repairs

Mining companies spend a lot on hydraulic repairs. When you have machinery, especially hydraulic machinery, working long hours in hot and dusty environments you’ll naturally experience wear and tear. Quite often, the initial failure will occur in one area and set off a chain reaction throughout the hydraulic system.

While it’s accepted that repairs to hydraulic cylinders, motors and pumps will be needed from time to time, there are ways to minimise the number or frequency of repairs. To help you keep your machinery running in top shape we’ve put together 5 tips to help you reduce hydraulic repairs, plus common hydraulic issues to look out for.

How To Reduce Hydraulic Repairs

Hydraulic Repairs

#1 – Maintenance

Basic regular maintenance should be carried out as needed. That may be measured in days, weeks or months or by the number of hours the machinery has been operating. Don’t wait until something is broken, keep your machinery calibrated and in working order.

#2 – Use Correct Fluids

It should go without saying that using the wrong fluids will cause damage to your hydraulics. Specifically, using the wrong oil with the wrong viscosity will result in lubrication damage and premature failure of major components, like cylinders. It can also increase the consumption of power, which over time will mean added costs.

#3 – Regular Check ups

Checking and testing the performance and accuracy of your machinery is essential. Even a slight drop in performance is an indication that something isn’t right. Left unchecked, that minor issue can turn into something major. 

#4 – Schedule Maintenance Checks 

Sticking to a maintenance plan will improve your overall production. Having a set schedule allows you to plan for any downtime, arrange for workers to have time off or order in replacement components that may be part of your planned maintenance.

#5 Use a Qualified Repairer

If you’re in charge of purchasing hydraulic machinery, you’ll know how big an investment it is. You should only trust a qualified and reputable hydraulic expert to carry out repairs or supply refurbished parts. 

Common Hydraulic Issues That Result In Repairs

If you notice any of the following issues during your regular maintenance checks, you should contact a Hydraulic repair expert.

Contamination

If foreign matter gets mixed with fluids this can cause hydraulic failure and greatly impact the performance and efficiency of the machinery.

Increased Pressure

Hydraulics should operate at specific pressure levels. If pressure rises, this can cause other wear and tear on a variety of components.

Aeration

Air bubbles within the hydraulic fluid is a dangerous combination. It can degrade the hydraulic fluid causing damage to the components through overheating, wearing out seals and affecting lubrication.

Cavitation

When hydraulic fluid doesn’t fill the space within the pump completely, possibly due to the pump moving too quickly, an intake line that’s too long or restricted or high fluid viscosity, cavitation occurs. It can produce the same high-pitched sound as an aeration issue.

Poor Viscosity

A specific level of viscosity needs to be maintained at all times within a hydraulic pump. If levels rise too much, it can cause cavitation. However, if viscosity levels are too low, too much heat will be produced, causing leaking.

Excessive Heat

While often a side effect of other problems, excessive heat can also be a cause. Too much heat is a warning sign that something isn’t working correctly and needs to be investigated immediately.
