Know About Different Applications and Mechanisms of Gas Spring

For those who are unfamiliar with gas spring and its uses, there is a lot to know beyond the terminology used for these products. It is used in different settings and has a wide range of categories that are based on its varied functional characteristics. To start with you must know that the gas spring products are extensively used to move masses. On the other hand, the dampers are used along with it in order to control the motion of these moving masses. Therefore, these products working in unison across several applications provides both load support as well as motion control functions.

Different Types of Gas Spring Available in The Market:

Ideally, there are two types of gas springs available and those are damped gas spring and locking gas spring. As for the literal definition of a gas spring, it can be said that these are hydro-pneumatic energy storage components. To provide compressible and damping motion control the mediums used are nitrogen gas and oil. A gas spring configured a wide range of requirements across different industries. Gas spring is duly attached with pressurized nitrogen and oil cylinder and you can find a precision rod between the gas spring and this cylinder. They create a pressure and balance the pressure from internal and external environments, and the rod is acting as a cross-sectional tool.

Gas Springs Equation

The mechanism of a gas spring consists of a precision rod that moves inside a sealed cylinder that contains nitrogen gas and oil. This cylinder contains pressurized nitrogen gas and oil and the force thus created balances equally the pressure differential between the internal pressure as well as the external environmental pressure. This piston acts on the cross-sectional area of the precision rod. The pressure differential for most of the applications can be estimated with the help of the internal pressure of the gas spring.

The Working Mechanism

When the piston rod is lead into the thin cylinder through compression stroke, the volume of gas inside it decreases. This results in a proportionate increase in the pressure foll

owing the well-known principle of Boyle’s Law. Subsequently, the force of the gas spring is eventually higher as the rod is inserted and compressed in the cylinder.

What is Gas Progression?

There is a significant difference between the forces at the two extreme ends of the rod positions. This is the most significant characteristic of the gas spring called the gas spring progression or the K-factor was commonly known as IGS. The benefits achieved through this process include:

1. Very low K-factor as compared to other mechanical springs

2. K-factors typically range from 1.05 to 1.8 for 80% progression

The gas springs are pre-loaded or pressurized unlike common coil springs producing better results and efficiency. The factors that are considered to determine the K-factor includes the forces, spring constant, the force change for each unit and the distance of deflection in mm.

How Would You Use the Gas Springs?

When you use a gas spring there are a few things to keep in mind. The list includes:

1. Consider the pressure vessels and never try to open it without following the proper instructions for "Recycling".

2. Never expose the gas spring to naked flames or excessive heat.

3. Make sure that the piston rod always points downwards when in use to ensure the better function and optimal lifespan.

4. Maintain an ambient temperature when using it so that it is between -30 and +80°C.

5. Never lubricate the piston rod with any oil, grease or expose it to any solvents.

As all gas springs are specially designed to handle only axial loads, you should not use it for radial or lateral forces and always use a big cross-section.
