Using the proper techniques is critical in hydraulic cylinder repair. You will need to make sure that your repairs are done safely and efficiently and that they will last as long as possible. There are some common causes of failure and some things you need to know before starting the repair process. These include the cost of repair, the testing you will need to do, and the common methods of repair.
Common causes of failure
Various factors can cause hydraulic cylinder failure. These include physical damage, fluid contamination, and improper maintenance. By understanding the causes of failure, cylinder owners can avoid common problems and ensure the cylinder continues to perform as designed.
A damaged seal is one of the most common causes of hydraulic cylinder failure. Seals are made of soft materials and are subject to wear and damage from dirt, dirt particles, liquid contaminants, and chemicals. Failure of seals can lead to leaks, jerking movements, and damage to cylinder components. A failed seal can also cause dirt to build up around the gland and lead to failure.
High-pressure conditions can cause seal failure, bending and breaking of cylinder rods, and ballooning of the cylinder barrel. These events can cause severe physical damage to the equipment, pump, or personnel.
A seal may become damaged due to a pressure spike or chemical erosion. A seal may also fail because of an excessively high temperature. It’s important to monitor pressure levels with a pressure monitor and ensure that the seal is compatible with the cylinder.
Common methods of repair
The repair process will vary depending on the type of cylinder and the damage. However, there are standard methods that can be used to make repairs.
First, a technician must remove the cylinder from the housing. This requires an engineering specialist and tools. The technician should look for signs of physical damage, such as scratches and bent welds. The technician should also inspect the cylinder for external leaks.
The technician should then plug the service ports. This will prevent moisture from entering the cylinder. In addition, the technician should clean the components. This should include the head, rod, and seals. After cleaning, the components should be dried with compressed air.
The technician should check for signs of damage, such as pitting, rust, and wear. These will indicate that the cylinder has been subjected to a corrosive environment. This can lead to corrosion and hydraulic cylinder pitting.
The technician should examine the cylinder bore. This is the area where the hydraulic fluid is stored. It is also where the seals and rod seals are located. If the seals are damaged, or the rod seals are worn, this can lead to leaks.
Testing required
During hydraulic cylinder repair, it is important to test the cylinder to determine its condition. This will enable you to detect leaks and identify the most likely sources of problems. Some manufacturers run special training for service staff on how to test hydraulic components.
Hydraulic cylinders should be checked and repaired on a regular basis. This will increase their lifespan. Typically, a properly maintained cylinder should last for decades.
The most common hydraulic cylinder repair problem involves leaks. This can be caused by a variety of different sources. You can detect leaks by carefully following pressure levels.
The most common leaks occur in the seals and welds of the cylinder. These leaks will occur if a seal or weld is misaligned, broken, or worn. They can also be caused by improper mounting. These leaks are often difficult to pinpoint, but they can cause major problems in the hydraulic system.
