Computer chair gas rod explodes

Generally speaking, the following two situations may cause an explosion: First, the thickness of the gas spring wall is uneven or the preload is too large. Second, frequent high and low adjustments and rotations can lead to overheating and explosion.

Under normal circumstances, this pressure rod, which is similar to a bicycle pump, is filled with high-purity inert gas nitrogen. When a person sits on a chair, although the nitrogen is squeezed and the pressure increases, it is still within the limit range of air pressure expansion and no problems will occur. Some low-quality air pressure rods often have problems such as insufficient nitrogen purity and shoddy air rod materials. When the temperature is high in summer or the seat is frequently raised and lowered, the pressure inside the air pressure rod rises suddenly, which can easily cause an explosion. In order to reduce costs, some unscrupulous manufacturers use free high-pressure air instead of inert gas, which makes it easier to cause the gas pressure rod to explode. In addition, some consumers' wrong practices when using pneumatic lift chairs also pose safety risks, such as using too much force when sitting or frequently adjusting the lift handle.
