A hydraulic cylinder typically transfers hydraulic fluid energy into a unidirectional force used for moving the cylinder from a unidirectional stroke. Hydraulic cylinders are common in the construction industry and are used to operate bulldozers, tractors, trenchers, excavators and loaders. But every so often the hydraulics within the cylinder can get damaged. These causes of failure will need intervention from a hydraulic cylinder service professional.
Rod Surface Is Too Smooth Or Too Rough
The rod surface plays a vital role in extending the shelf life of the seal. If it is too smooth, then the shelf life of the seal may fall thanks to lack of proper lubrication through the system. If it is too rough, then the rod seal may start to spring leaks because of too much friction. This may result in pollutants entering the system. You should ideally get a hydraulic cylinder service to add chrome plating to the rod surface to extend its lifespan for the long haul. A professional may also recommend additional protective measures to help improve the performance and shelf life of the rods and seals.
Cylinder Rods Begin To Twist
After constant use, you may notice the rods of the hydraulic cylinder starting to twist and warp. This may happen because the material isn't strong enough or because the diameter of the rod is too thin. If the cylinder hasn't been mounted properly onto the application, then this may also cause the rods to twist. After the rods twist, tremendous pressure is put on the seal, which could result in leakages and eventual failure. A professional hydraulic cylinder service will need to diagnose and fix the problem by replacing or repairing the rods.
Cylinder Tubes Start To Swell And Damages The Piston Seal
Cylinder tubes can start to swell because of thin walls and poor strength of the material, both of which are unable to handle the operating pressure of your hydraulic cylinder. If the cylinder tubes start to swell, then the accurate pressure between the wall and piston seal is reduced. This will enable fluid to pass through the seal at high pressures. The high pressure can cause tremendous damage to the seal through overheating. This reduces the life of the piston seal drastically. The hydraulic cylinder service will not only have to check the piston seal, but also they will need to fix the walls of the cylinder tubes to stop this problem from recurring frequently.
These devices are vitally important to enabling large machines to function accurately, so make sure a professional hydraulic cylinder service intervenes when you notice any of these problems to prevent irreparable damage.Share
