Dangers of Office Chair Cylinders
Office chair cylinders do pose certain risks, but those produced by reputable manufacturers generally do not explode. The dangers are mainly reflected in the following aspects:
Risks of Low-Quality Pneumatic Rods: Low-quality pneumatic rods can be considered as "time bombs", with three main reasons for their explosion. Firstly, some unscrupulous manufacturers reduce costs by filling the pneumatic rods with compressed air instead of nitrogen. When the temperature rises, the compressed air may ignite the lubricating oil inside the rod, leading to an explosion. Secondly, if the quality of the steel tube is subpar, during normal use, the internal pressure of the pneumatic rod can reach 24 atmospheres, and low-quality steel tubes are prone to cracking under such high pressure. Thirdly, improper use is also a significant factor. For example, frequently operating the lifting lever or placing the chair near heat sources such as radiators can increase the risk of explosion.
Material Issues of Pneumatic Rods: The material of the pneumatic rod itself is crucial. If unqualified materials are used, their strength and toughness cannot meet the requirements for normal use, making them prone to deformation or even rupture under pressure, which can lead to serious consequences such as explosions.
Gas Purity and Sealing Issues: Pneumatic rods are usually filled with nitrogen. When the gas purity is below 90%, there may be safety hazards. Additionally, the sealing performance of the pneumatic rod cannot be overlooked. If the sealing is not tight, gas can easily escape, which not only affects the normal use of the chair but may also cause harm to the user.
Cutting Corners in Production: Some unscrupulous merchants, in pursuit of profit, cut corners during production, resulting in substandard wall thickness of the pneumatic rods. When a person sits on the chair, the air chamber above the piston is compressed, and depending on the person's weight, the air pressure can increase to 18 - 25 atmospheres. This further increases the pressure on the already thin cylinder wall, increasing the likelihood of an explosion.
