The GUDEN Compression and Extension Dampers Deep Dive
1. What is a Standard Damper?
Dampers are a unique product made with a rod and tube construction filled with lubrication oil and an orifice plate and other internal mechanisms for oil flow between the chambers. Without an orifice plate pack inside the tube, the rod would compress into the tube and the oil would flow freely to the other side of the chamber and there would be no dampening. But with an orifice plate in place, when the rod is compressed into the tube, the oil is essentially squeezed from one side to the other by passing through the orifice plate. This action of oil passing through the orifice plate is what creates the dampening. Our dampers are available in a wide range of sizes, from our Compact-Size (6mm x 15mm) and Standard-Size (8mm x 18mm) dampers. So no matter your needs, we have the right size for your project.
How is the Damper speed controlled?
The size of the orifice plate is what controls the strength of the dampening. The larger the orifice, the less dampening there will be and vice versa. But this is also affected by the outside temperature, oil gets thicker in the cold, as well as the weight of the door or cover.
What style or types of Dampers are available?
Dampers are available in an extension style for dampening when the damper rod is coming out from the tube and a compression style for when the rod is entering into the tube. It is also possible to have dampening in both directions.
How do I design a Damper into my application?
Just like gas springs, the proper mounting should undergo an engineering process for which size and what mounting locations are needed for your requirements. The weight and size of your door or cover and the distance you expect it to open will be needed for the design. It is also highly suggested to do some sample testing to make sure the speed of dampening is what you are looking for if you don’t have an inches-per-second style measurement on the movement of your door.
How should a damper be installed?
Dampers are supplied with threaded ends. You can choose from a wide variety of end fittings such as the popular plastic ball socket. We also carry a metal ball socket for even more strength. These both join with either a threaded ball stud or a ball stud mounted onto a flat or angled bracket. Other end fittings such as metal blades, fat blades or clevis style are also available.
