Shock absorbers are a vital component of your vehicle. They are designed and built to help lighten the body’s load, cumbersome items like tailgates and bonnets.
This involves a sealed system with a cylinder containing pressurized nitrogen gas (this is a neutral gas that makes up 80% of the earth’s atmosphere) and oil.
Gas springs are used in various applications, from helping lift the hatchback tailgate of your car to keeping office chairs upright and ergonomic. They’re generally very durable and require minimal maintenance.
But, they can overheat if used in settings outside their design limits, like exposure to high temperatures, corrosive chemicals, or excessive physical stress. This can shorten their life span and possibly even cause them to malfunction.
SPD gas springs shocks like a super-sturdy bicycle pump but is filled with pressurized nitrogen gas (the principal constituent of the air around us) and oil to create a sealed system. The gas allows the spring to store energy, while the oil damps (slows and smoothes) movement and provides lubrication. Depending on their design, a gas spring’s cylinder may have one or more intake and outlet valves to control the flow of gas and oil. It can also contain a piston rod that moves back and forth inside the cylinder to compress the nitrogen gas when it’s being pushed on.
Gas springs (also known as gas struts or dampers) supply pushing force to lift, lower, and support the motion of objects such as doors, hatches, and equipment lids. The main components of a gas spring are a piston rod, cylinder, and pressurized nitrogen gas (a neutral element that makes up around 80% of the earth’s atmosphere).
Because gas springs contain high-pressure nitrogen gas and lubricating oil, they require little maintenance and are not subject to the same wear as coiled metal springs. However, it’s important to avoid using gas springs in settings they were not designed for, as this will cause them to wear out quickly and potentially break down completely.
If a gas spring is damaged, it may lose its ability to lift or support a heavy object, resulting in damage to the item the strut is supporting and possible injury to anyone nearby. To check for this issue, look for a pressure loss in the spring cylinder or signs of leakage from the seal.
Shock Absorber Failure
Unlike traditional springs that use physical deformation, gas springs pneumatically store energy as high-pressure compressed gases in a cylinder. This allows them to lift, lower, open, close, and adjust various objects quickly and precisely.
They manage to trap this energy through a combination of liquid and seals; the cylinder contains pressurized nitrogen (which happens to be a neutral gas that makes up around 80% of the earth’s atmosphere, so it’s not dangerous) and oil. This system is then sealed to prevent any leaks or loss of pressure.
As a result, gas springs mustn’t be put in settings they were not designed to be used in; doing so could lead to them wearing out or breaking down completely. Furthermore, disassembling a new gas spring or welding it is not advised; both actions could cause the cylinder to explode and seriously injure the user.
Shock Absorber Replacement
Gas springs (gas shocks/absorbers or gas pistons) are versatile hydro-pneumatic lifting mechanisms used in all sorts of places to help make it easier to open and close doors, hatches, lids, seats, etc. They receive operating pressure from highly pressurized (compressed) gas and store the energy as potential power, freed when the piston that seals the energy lifts.
Rather like a super-sturdy version of a bicycle pump, they use a cylinder filled with pressurized nitrogen gas (a neutral, non-toxic substance that makes up around 80% of the earth’s atmosphere) and oil that is completely sealed so that the gas and oil cannot escape, allowing them to absorb and dampen vibrations.
When searching for a gas strut, technical specifications include the cylinder diameter or maximum width, compressed and extended lengths, load capacity, and complete cycles per minute. You should also know physical specifications such as the rod diameter, mounting options, and working temperatures.
