How to repair the hydraulic cylinder rod
Hydraulic cylinders can be repaired, but you should never attempt these repairs on your own. Although hydraulic cylinders have a simple design, you must be familiar with them in order to efficiently repair them. When a technician performs hydraulic cylinder repairs, they take the entire mechanism apart and reassemble to find the root cause of the issue.
COMMON POINTS OF HYDRAULIC CYLINDER FAILURE
There are several common points of hydraulic cylinder failure. These include the piston, cylinder rod, seals, and head.
PISTON
The pistons in hydraulic cylinders are one of the most common points of failure. This is especially true in light-duty applications. The pistons used in light-duty applications are often made from aluminum, which wears out much more quickly than the steel used in heavy-duty applications.
When checking pistons for failure, technicians will often measure the diameter of the piston. The piston’s diameter in relation to the bore directly affects the amount of hydraulic pressure that the piston is able to deliver. If there are issues with your piston’s measurements, it will need to be replaced, along with any wear band that is installed.
ROD
Rods are perhaps the most likely culprit of a hydraulic cylinder failure. Rods often develop small cracks after long periods of heavy use. A technician will use a special dye to check for cracks in the rod.
Bent hydraulic cylinder chrome bars commonly cause hydraulic cylinder failures. A rod only needs to be bent very slightly for the cylinder to fail. One of the easiest ways to check for a bent rod is to inspect the chrome finish. If it is bright and shiny on one side, but worn off on the other, the rod is bent. Thankfully, bent rods can often be repaired by straightening in a press.
SEALS
There are seals on both the piston and the rod of a hydraulic cylinder. If these seals leak, the cylinder will not be as powerful. Additionally, all of the oil will eventually leak out and the cylinder will fail. Unfortunately, damaged seals are often signs of more serious problems. While the seals themselves should certainly be replaced, the piston and rod should also be inspected.
A piston seal failure often indicates that the barrel has become distorted. Sometimes, the barrel is the only thing that needs to be replaced, but sometimes a distorted barrel is often caused by a problem with the piston. If this is the case, the entire cylinder must be replaced.
WHAT IS THE ADVANTAGES OF OUR Hydraulic cylinder ROD?
- Carbon steel balances durability, hardness, and wear resistance using formability, weldability, and durability;
- Chrome plating provides corrosion resistance along with an Extremely reflective look
- High precision tolerances, which ensures when used to make hydraulic piston rod, it can fit the cylinder precisely.
- Good Hardness: the surface hardness attaining HV850 minimal and upward, which not only help improve wear resistance but also help extend the life span of these chrome plated rods, thereby helping the consumer save the cost.
