How do we fix these problems? If there’s a bend, the rod can be straightened using a press. Re-chroming the rod will eliminate most surface damage, and is a relatively simple process for an experienced technician. It is also helpful to periodically rotate the hydraulic cylinder (like you would vehicle tires), or to swap it for an alternate. These measures can significantly extend the lifespan of your hydraulic cylinder.
Another important component is the hydraulic oil. As the most commonly-used type of hydraulic fluid, keeping your oil clean is part of basic maintenance. It should be checked regularly for any contamination—a typical cause of system malfunctions. The oil filter also requires regular cleaning and occasional replacement. Don’t underestimate the value of hydraulic oil maintenance to your heavy equipment.
Finally, the piston and piston seal are key parts of any hydraulic cylinder. Pistons are connected to the piston rods, and serve mainly to separate pressure zones within the cylinder barrel. Piston seals must be regularly inspected and carefully maintained to prevent fluid leaks and ensure smooth operation. Seals can be either single or double acting.
You mentioned hydrostatic testing for hydraulic cylinders. How does that one work? I’d like to know more because I think something is wrong with this piston I am working on. I think I may need a replacement part too. https://www.cincinnatidriveline.com/hydraulics
