How to choose the right air spring shock absorber for industrial equipment

1. Determine basic parameters

• Load requirements

1. Calculate the total weight of the equipment (including static and dynamic loads) to ensure that the load-bearing capacity of the air spring matches.
2. Consider load distribution (e.g., when supporting multiple points, the load must be evenly distributed).
3. Reserve a safety margin of 10% to 20% to prevent overload.

• Stroke requirements

1. Determine the vertical displacement range of the equipment during operation (e.g., lifting and vibration amplitude), and select a model with a stroke greater than the maximum displacement.

• Size restrictions

1. Measure the installation space (height, diameter) to ensure that the air spring can physically fit and leave space for inflation/deflation.

2. Analyze the working environment

• Temperature range

High temperature environments (e.g., metallurgical equipment) require heat-resistant materials (e.g., fluororubber seals); low temperature environments (e.g., cold storage) require anti-embrittlement design.

• Corrosiveness

Choose stainless steel housings or anti-corrosion coatings for chemical or marine environments.

• Cleanliness

Food/pharmaceutical industries require FDA-certified materials to prevent contamination.

3. Clear performance requirements

• Shock absorption effect

For high-frequency vibration (such as stamping machines), choose models with low natural frequencies (such as 1~3Hz); low-frequency vibration (such as large fans) requires higher damping.

• Stability

Precision equipment (such as optical instruments) needs to be equipped with a height valve to maintain levelness.

• Response speed

Equipment with fast dynamic load changes (such as robotic arms) requires a fast-response airbag design.

4. Choose the type of air spring

• Ball air spring

Advantages: large stroke, high load, suitable for heavy equipment (such as injection molding machines).

Disadvantages: poor lateral stability, requires a guide mechanism.

• Membrane air spring

Advantages: compact, fast response, suitable for space-constrained or precision equipment (such as semiconductor manufacturing machines).

Disadvantages: small stroke.
