8 problems encountered during the use of gas springs

Gas springs are mechanical devices that utilize compressed gas to exert force. They are commonly used for supporting, lifting, or positioning objects such as vehicle tailgates, office chairs, and various types of machinery and equipment. Despite their widespread application and numerous advantages, users might encounter several problems during the use of gas springs. Here are some of the common issues:

1. Leaking: The most common problem with gas springs is the loss of gas, which can occur through seals or microscopic pores in the cylinder wall. This can lead to a decrease in pressure, reducing the spring's ability to support weight.

2. Corrosion: The external shaft of the gas spring can corrode if exposed to harsh environments, leading to pitting or scoring. This not only weakens the structural integrity of the spring but can also damage the seal as the shaft moves through it, increasing the risk of gas leaks.

3. Wear and Tear: Over time, the seals within a gas spring can wear out, especially if the spring is used frequently or in high-stress applications. This can lead to internal leaks where the gas can escape, reducing the performance of the spring.

4. Temperature Effects: The performance of gas springs can be significantly influenced by temperature changes. High temperatures can increase the internal pressure, potentially leading to overextension or failure of the containment vessel, while low temperatures can decrease the pressure, diminishing the lifting power of the spring.

5. Noise: Gas springs can sometimes produce noise during operation, such as squeaking or popping sounds. This could be due to a lack of lubrication, improper installation, or internal component issues.

6. Improper Specification: Selecting a gas spring without the correct specifications for the intended application (e.g., force, stroke length, dimensions) can lead to inadequate performance or premature failure.

7. Over-extension or Over-compression: Using the gas spring beyond its designed maximum extension or compression limits can damage the internal components, leading to failure. This might happen if the application demands more from the spring than what it's rated for.

8. Mounting Issues: Incorrect installation or mounting can lead to uneven wear and tear, seal damage, or undue stress on the cylinder or piston rod, affecting the operation and lifespan of the gas spring.

To mitigate these problems, it's essential to:

• Select the appropriate gas spring for your specific application, considering factors such as force requirements, environment, and temperature range.
• Install the spring correctly, following the manufacturer's guidelines, especially concerning orientation and mounting points.
• Perform regular maintenance checks, looking for signs of wear, leaks, or corrosion, and replace the gas spring as necessary.

By understanding and addressing these potential issues, users can ensure the reliable performance and longevity of their gas springs.
