Hydraulic Cylinder Common Problems and Solutions

1. Hydraulic Cylinder Common Problems and Solutions Every piece of machinery has the potential to fail. Some of the issues may be simple to fix, while others will necessitate entire machinery replacement. This will mostly be determined by how effectively the machinery is maintained. Poorly maintained machinery can lead to major breakdowns and have a negative impact on performance. The topic to be discussed here is frequent hydraulic cylinder issues and remedies. Hydraulic cylinder jacks are an integral part of every application in which they have been employed. The hydraulic cylinder's function is essentially identical to that of human muscles, making the apparatus stronger while managing big weights. The hydraulic cylinder's piston rod extends or retracts withstanding a significant weight due to the supplied hydraulic pressure. Failure or even catastrophic effects will almost always occur from a lack of thorough inspection, preventative maintenance, faulty cylinder design, and incorrect installation. However, before the system completely fails, it will display specific indications that will aid in the early detection of the problem. Some common symptoms of hydraulic cylinder failure are listed below in points. ●Unpleasant pounding or knocking noises are caused by air in the hydraulic cylinder, cavitation, and pollution. ●The hydraulic cylinder piston and rod movement will be hampered due to a lack of lubrication and increased friction. This is referred to as "slip-sticking" or "juddering." ●Due to fluid leaks and increased friction, energy consumption has risen. ●Overheating of the cylinder is also an indication of a malfunctioning system. ●The piston rod will wear due to misalignment, high lateral stress, and other external wear. After you've figured out the warning indications of hydraulic cylinder failure, the following step is to figure out what's causing the problem. This will be useful for determining the cause of failure, as well as inspection and maintenance. The following are the most common causes of hydraulic cylinder failure that might aid with troubleshooting: Damaged piston rod and rod bearing: The hydraulic cylinder will provide linear motion to the associated load, allowing the system to function normally. The piston and rod arrangement is critical in the cylinder, because bent piston rods, undersized rods, and poor alignment between the cylinder and its load cause damage to piston rods and rod bearings (which is called sideloading). Contaminated Fluid: Every hydraulic component in the system is at risk from the contaminated fluid. Contamination will result in early rod seal failure in hydraulic cylinders. Premature rod

The use of adequate filtration technologies in hydraulic systems is a viable solution to this problem. Extreme Temperature: The hydraulic system's components are all intended to endure a certain temperature range. It will undoubtedly destroy the component as well as the hydraulic fluid qualities if it surpasses the prescribed value. When the temperature rises, the hydraulic cylinder seals become hard, fractured, and brittle. Chemical attack: Some incompatible fluids will chemically react with cylinder and seal materials, causing corrosion and other wear. This problem may be avoided by using a suitable hydraulic fluid. High-pressure or low-pressure leaks: Hydraulic cylinder drift, in addition to fluid loss and accompanying risks, is a severe worry of fluid leakage. Seal deterioration, faulty assembly, and a lack of maintenance can contribute to leakage.
