Hydraulic cylinders are devices used in many sectors of activity such as industry, construction, agriculture or transport. This device which has been around for several centuries and therefore the operation is both simple and brilliant, ingenuity is exposed to incredible forces. If not taken care of, it can be damaged and break down. Good practices make it possible to increase its lifespan. Find out which ones.
Change seals regularly
The first source of wear when using a cylinder occurs at the rubber seals that close and seal the various chambers containing hydraulic fluid. These small parts are responsible for retaining all the pressure injected into the cylinder. It is therefore normal for them to deteriorate over time. If stored for too long, they will eventually fail, leading to external fluid leakage. When it comes to this, the cylinder stops working. This is also why when companies like SAH Leduc Repair face breakdown problems, the rubber seals are systematically changed to postpone the deadline for a seal failure.
Never force the cylinder
This is one of the major causes of malfunction: hydraulic cylinders are equipment capable of deploying very great mechanical power. Sometimes when using such a tool, you find yourself near the limits of its capacity. For example, when you have a very heavy load to carry or a material that is particularly hard to break. The manipulator may then be tempted to force the piston. This is exactly what to avoid. This is because the rod is designed to absorb some resistance. If you exceed this level of engagement, it can twist, rendering the cylinder unusable.
As a result, we have to straighten it or replace it, which represents a significant cost and above all, requires a lot of technical equipment to dismantle the circuit. hydraulic.
Drain the oil regularly
The fluid which pressurizes which allows the hydraulic cylinder to exert significant mechanical forces is mineral oil. The latter can wear out over time. For example, there may be air bubbles entering the circuit or simply oil fatigue.
When this crystallizes, there is a risk of having small pieces that scratch the inside of the barrel. As a result, we end up with sealing problems leading to fluid leaks.
To avoid this, it is recommended to purge the liquid regularly. It is therefore necessary to disassemble the various components of the cylinder and drain off the mineral oil.
Each element is then reassembled in order and the liquid is re-injected into it, which must then be pressurized.
This must be done using a hydraulic bench in which an external circuit is connected to regulate the pressure of the circuit.
By following these few tips you can be sure to guarantee the proper functioning of your equipment, thus significantly increasing its lifespan and its capacities over time.
