Things To Know Before Buying Or Customizing A Gas Spring

There are many great pieces of technology around us that can go unnoticed. But these can be highly essential in daily lives. Consider the instance of the gas spring. Do you ever notice its presence? If you have adjusted a swivel chair at work today or opened the car boot, you may have already used the device without even noticing how the small object can enhance convenience.

Technical Concept

The gas spring is a self-contained and hydro-pneumatic cylinder. It can generate a considerable force that aids in moving and positioning the lids, tabletops, chairs, and plenty of other assemblies. You do not need to perform any regular maintenance job on the cylinder. The pressure is the result of the pre-charging of the cylinder with nitrogen gas. When you apply pressure to the piston and the diameter area, a force will be exerted that will lead to the release in the case of push-type gas springs.

  • The springs depend on the pressurized gas and the oil-based lubricants which are present for supporting the external forces. 
  • The presence of compressed gas maintains energy efficiency as it controls the way of the storage and emission of the energy through a smooth and cushioned movement procedure. 
  • The transfer of pressure through the gas spring happens via the rod and sliding pistons. 

As you now know about the technical features of the dampers, it is time to learn about the uses and benefits of the incredible springs. 

Basic Mechanism

If you want to order the right form of the springs, you first have to know about the parts and how these help in the work mechanism. The maintenance-free cylinders contain pressurized nitrogen gas. 

On pushing the piston rod, it compresses the gas further, generating an output force and it controls the velocity by metering nitrogen from a tiny hole. Some of the gas spring can even have a vent valve with field accessibility that aids in venting nitrogen for the reduction of the output force.

Types Of Springs

While choosing the right type of springs, you have to know about the various types available in the market. 

  • Push type: If you need to lower or lift the loads easily and with minimum exertion, then this type of spring will be ideal. It can support the lids and covers in industrial machines where manual operation is not possible.
  •  Pull type: This type of gas spring will be a compact one that can fit in tight, regardless of the position or orientation. In this type, the pressure will retract the piston rod, and so, the progression rate is lower. Progression is the increase in the force exertion of the spring over each stroke. This type of spring will cause an 11% progression rate. 

Provide Correct Information

If you want to get hold of the right spring, you need to share the requirements with the designer elaborately so that the manufacturer can implement the features accordingly. 

  • Orientation: You need to understand that the gas spring body should fit within the machine’s assembly, and there should be no obstacle around to hinder the motion range. 
  • Pivot point: This point, which is popular by the term hinge, can provide the necessary support to the gas springs. It is the axis of the rotation of covers, hoods, or any other rotating objects. You need to specify whether it should be at the top, middle or bottom. 

Finally, you also need to provide complete details of the size and weight of the objects that need to be handled using the spring. It will help the manufacturer to customize the design to make it suitable for your work. 

After reading this article, you know all the relevant information there is about gas springs. You can now make an informed decision regarding the type that you should order.
