Hydraulics are an increasingly common aspect of today’s mechanical world. Alongside conventional motors and electronics, you can find hydraulics everywhere from industrial machinery to everyday households. With that said, hydraulic piston repair is more important than ever.
This means that the costs of hydraulic repairs are increasingly common. Keeping an eye on your hydraulic systems can reduce your operating costs and save you from having to replace and entire machine. Let’s take a look at 5 signs you need hydraulic piston repair.
Look Out for Particulates
A clean shop is a safe shop as the old saying goes, but this is also true for hydraulic piston repair. Small particulars like sawdust, metal shavings, and fiberglass can contaminate your hydraulic system and damage parts. Hydraulics may be tough, but their pistons are designed to fit with mathematical precision. Keep your shop clean to prevent particulate matter from degrading your hydraulics.
Stopping Rods from Bending
Hydraulic rods begin to bend over time for a variety of reasons. One of the most common is that their fit is wrong. If a rod is fitting too tightly it will experience undue pressure and lose its shape over time. Likewise, if it is too small it will rattle around in its housing causing the same problem. When you change rods, make sure you are following the manufacturer’s specifications for sizing and parts. Remember that bent rods snap and that can break and entire machine resulting in a much higher repair bill.
Coating and Finishes
Hydraulic pistons are coated to ensure proper operation. Over time, these coatings and finishes can start to degrade. Once a coating has worn down, the piston rod will start to grind against the housing and that will damage the overall hydraulic system over time. In order to prevent this, make sure your coatings are refreshed at the first sign of wear.
Bearings are constantly moving in hydraulic systems. For bearings to maintain functionality, they need to be both routinely greased and make sure their housing isn’t degrading. If your hydraulic system starts making unexpected grinding noises, inspect the bearings for damage.
This one is tricky. Most hydraulic system should not balloon. A ballooned tube or piston rod is caused by the rod’s metal being insufficiently strong to handle the operating conditions of the hydraulics. This usually happens due to a mistake in the initial manufacturing or by a repair job using the wrong parts. Make sure to replace piston rods with your manufacturer’s recommended parts as fit is just as important as overall construction.
