Office Chair security issues need to pay attention
Recently, a news was aroused the attention of the chair and panic, Xiamen computer chair a woman exploded, was inserted into the lower body pressure bar chair lift. Because the lift chair itself has many advantages, it is very popular, and now basically offices are using the chair lift. But chairlift bombings in recent years has caused consumer panic, especially office workers who often come into contact. Careful analysis of today for everyone to look at why the chair will explode, and how to avoid explosion prevention chairs.
Chairlift cause of the blast
Currently, the lifting device on the market using the chair lift into three categories --- hydraulic, mechanical and pneumatic. At the low end of the chair lift to the pressure of the majority.
Pneumatic lift chair has a pneumatic rods, pneumatic rod is a kind of gas and liquid as the working medium, can play a supportive cushioning, braking, adjusting the height and angle adjustment and other functions of the elastic element, the basic principle is the internal charge high-pressure nitrogen gas, since the inside of the piston has a through-hole, the gas pressure across the piston equal, but different sides of the cross-sectional area of the piston, the piston rod has one end and the other end does not, under gas pressure, to produce a small cross-sectional area pressure side, namely the pressure rods stretch, people sit on the lift shaft to the pressure, then gently lift shaft fall, uniform speed, can be reduced to the lowest point. Not to force the lifting axle, lifting axle lift highest point on the back. It is understood that the regular manufacturers are filled with nitrogen gas spring, usually in concentrations above 99%, about atmospheric pressure in one or two.
This regular chair lift, there are three general situation may explode: First, lack of nitrogen purity, high temperature environment or rubbing too often the case, can lead to overheat the cylinder pressure becomes large explosion may occur; the second is a cylinder container wall is not strong enough or poor material, explosion may occur; the third is sealed Mifengbuyan dense, causing gas bursts.
Most of the market sales of office tools on display in the store are not marked chairlift manufacturer, origin, trademark, just like a "three non-product", and this "three non-product" because of its low price, the market is relatively selling. However, black manufacturers in order to lower the costs, filled with high-pressure air is even more likely to cause an explosion.
How to prevent
Pressure is not all chairlifts will happen "explosion" of a furniture dealer is this? Answer: Pressure great explosion is a probability event, good pressure bar explosion probability will be low, probably less than one ten thousandth , while the probability of poor pressure bar explosion will be high. If so, then the probability of this event how to minimize it? For no explosion protection chairlift event of an explosion, it will directly hurt the person. Want your chair safer? Then the following four points better pay attention:
First, be sure to purchase a quality certification and safety certification brand, in fact, the national security risks with these products have more stringent monitoring, so the time of purchase can not be cheap;
Second, the chair is in use, do not repeatedly lift;
Third, if not a professional, do not open the cylinder, do not let the chair near the hot things, such as roast stove or oven;
Fourth, after a period of use, it should be in time for professionals to check, once the cracks were found to loosen, timely maintenance and replacement.
Especially pneumatic lift chair lift chair although there may be an explosion, but as long as we buy the regular manufacturers factory, safe and reliable quality chair lift, with no time to use their usual frequent movements, identify problems and take manufacturers maintenance, the probability of an explosion chair lift will be much smaller.
