Corrosion is a silent yet potent threat that can significantly undermine the performance and longevity of reach stackers cylinders. As a supplier of Reach Stackers Cylinder, I've witnessed firsthand the far - reaching impacts of corrosion on these crucial components. In this blog, we'll delve into the science behind corrosion, its effects on reach stackers cylinders, and the preventive measures that can be taken.
The Science of Corrosion in Reach Stackers Cylinders
Corrosion is an electrochemical process that occurs when metal reacts with its environment. In the case of reach stackers cylinders, which are typically made of steel or other metals, the presence of moisture, oxygen, and certain chemicals can initiate corrosion. When the metal surface is exposed to these elements, an oxidation reaction takes place. Iron, a common component in cylinder materials, reacts with oxygen in the presence of water to form iron oxide, commonly known as rust.
The reaction can be simplified as follows:
[4Fe + 3O_{2}+6H_{2}O \rightarrow 4Fe(OH){3}]
The iron hydroxide further decomposes to form rust ((Fe{2}O_{3})). This rust layer is porous and does not provide effective protection to the underlying metal, allowing the corrosion process to continue.
Impact on Performance
Loss of Hydraulic Efficiency
One of the most immediate impacts of corrosion on reach stackers cylinders is the loss of hydraulic efficiency. Corrosion can cause pitting and roughness on the internal surface of the cylinder bore. As the piston moves within the cylinder, these irregularities increase friction. The increased friction not only requires more energy to move the piston but also leads to a reduction in the smoothness of the cylinder's operation. This can result in jerky movements of the reach stacker's lifting and stacking mechanisms, which can be dangerous and reduce the overall productivity of the machine.
Seal Damage
Corroded cylinder surfaces can also cause significant damage to the seals. The seals in reach stackers cylinders are designed to prevent hydraulic fluid leakage and maintain the pressure within the cylinder. When the cylinder bore is corroded, the sharp edges and pits can cut or wear down the seals. Once the seals are damaged, hydraulic fluid can leak out, leading to a loss of pressure. This not only affects the cylinder's ability to generate the necessary force but also results in environmental contamination and increased maintenance costs due to the need for frequent seal replacement.
Reduced Load - Carrying Capacity
The structural integrity of the cylinder is compromised by corrosion. Rust weakens the metal, reducing its strength and load - carrying capacity. A reach stacker cylinder is designed to lift heavy containers, and any reduction in its load - carrying capacity can be a serious safety hazard. If the cylinder fails under load, it can cause the container to fall, endangering the operators and other personnel in the vicinity.
Impact on Longevity
Shortened Service Life
Corrosion accelerates the wear and tear of reach stackers cylinders. The continuous degradation of the metal due to corrosion means that the cylinder will reach the end of its service life much earlier than expected. This requires more frequent replacement of cylinders, which is a significant cost for reach stacker operators. Additionally, the downtime associated with cylinder replacement can disrupt the normal operation of the port or warehouse where the reach stacker is used.
Increased Maintenance Costs
As corrosion progresses, the maintenance requirements for reach stackers cylinders increase substantially. In addition to seal replacement, other maintenance tasks such as cylinder honing or re - plating may be necessary to restore the cylinder's performance. These maintenance procedures are time - consuming and expensive. Moreover, the need for regular inspections to detect early signs of corrosion adds to the overall maintenance cost.
Preventive Measures
Coating and Plating
One of the most effective ways to prevent corrosion in reach stackers cylinders is to apply protective coatings or platings. For example, chrome plating can provide a hard, corrosion - resistant surface on the cylinder bore. The chrome layer acts as a barrier between the metal and the corrosive environment, preventing oxygen and moisture from reaching the underlying metal. Other coatings, such as epoxy coatings, can also be used to protect the external surface of the cylinder from corrosion.
Proper Lubrication
Lubrication plays a crucial role in preventing corrosion. A high - quality hydraulic fluid not only lubricates the moving parts of the cylinder but also provides a protective film on the metal surface. This film helps to prevent the formation of rust by keeping oxygen and moisture away from the metal. Regular fluid analysis and replacement are essential to ensure that the lubricant maintains its protective properties.
Environmental Control
Controlling the environment in which the reach stackers operate can also help to prevent corrosion. For example, storing the reach stackers in a dry, covered area can reduce their exposure to moisture. In ports, where the air may contain saltwater spray, installing air filtration systems can reduce the amount of corrosive particles in the air.
