Temperature can be a very big factor in how a gas spring operates in an application. The gas spring cylinder is filled with nitrogen gas and the higher the temperature, the faster the gas molecules move. The molecules moving faster, causes the volume of gas and pressure to increase which makes the gas spring stronger.
The effect of temperature on gas springs can manifest in various ways, influencing their performance and behavior. Here are some key effects of temperature on gas springs:
Firstly,the pressure inside a gas spring is directly proportional to the temperature according to the ideal gas law. An increase in temperature leads to an increase in pressure, and conversely, a decrease in temperature results in a decrease in pressure. This pressure variation can impact the overall force exerted by the gas spring.
Secondly,temperature changes cause the gas inside the spring to expand or contract, leading to changes in volume. This can affect the overall length and extension of the gas spring. In applications where precise control of movement is critical, temperature-induced volume changes need to be considered.
Thirdly, temperature changes impact the overall dimensions and structural integrity of the spring, potentially affecting its performance and the integrity of seals in the gas spring.
Lastly,gas springs often contain oil or grease for damping purposes. Changes in temperature can alter the viscosity of these fluids, influencing the damping characteristics of the spring. This, in turn, affects the speed and smoothness of the spring's movement.
Knowing the temperature environment your gas spring will be used in for the majority of the time is helpful. It will allow you to engineer the best mounting points and proper gas pressure to try to compensate for the temperature. More often than not, you won't be able to compensate for both the extreme heat and cold, but you can allow for optimal performance through a wider span of the operating temperature range.
