一声巨响过后，正在用电焊修椅子的工人手捂着左眼倒地，表情痛苦。

After a loud noise,Are using welding repair chair workers hand holding down the left,Expression pain.

　　正是面前这把升降椅突然爆炸，碎片崩坏了护目镜，才让他受了伤。

Before it is the chair lift sudden burst,Debris collapse the goggles,Just let him injured.

　　升降椅爆炸的事件屡见不鲜，其中不乏有人因此殒命。到底是什么原因，让一把看似普通的椅子成了“夺命炸弹”？

Chair lift explosion event common occurance,There is no lack of among them someone so perish.Exactly what reason be,Let a seemingly ordinary chair became"Seizes a life bomb"?

　升降椅爆炸崩伤眼睛 Chair lift explosion avalanche hurt eyes

　　9月18日下午1时许，54岁的张勇(化名)会电焊手艺，一个朋友拿来一把坏掉的气压升降椅，升降杆处有个地方断了，想叫老张给焊上。

On September 18, afternoon at about 1,54 zhang yong(alias)Will welding craft,A friend took a broken barometric chair,Lifting lever place there is a place is broken,Want to call Mr. Zhang to welding on.

　　老张一看这容易，也没多想，就打开了设备，戴上护目镜，开始工作。谁承想“咣”的一声巨响，受热后的升降椅突然爆炸，老张的护目镜碎了，左眼鲜血直流。

Lao zhang a look this easy,Did not want to,Open the equipment,goggles,Began to work.Who ChengXiang"MAO"A loud bang,After heated the chair lift sudden burst,Lao zhang goggles broken,Left eye blood dc.

　　家人赶紧把老张送到了鞍山市中心医院，眼科姚建新主任检查后发现，患者的左眼眼球晶体受损，里面清出杂物。“先保眼球，如果能行，再想办法恢复视力。 ”姚主任当即这样决定。

Family put Lao zhang to the anshan central hospital,Eye YaoJianXin director examination found,Patients with retinoblastoma crystal damaged,It clear the sundry."First the eyeball,If can do,To think of a way to restore vision. "Yao director promptly such decisions.

The doctor immediately for zhang yong carried out surgery,But he can restore vision not sure yet.

升降椅什么情况会爆炸？ Chair lift what circumstance will explode?

　　升降椅怎么会成了坐在屁股下的“炸弹”？它的内部充的是什么气体？

Chair lift how can sit under a bottom"bomb"?Its internal imitation is what gas?

　　鞍山市新兴教学设备厂白先生介绍，目前市面上出售的很多升降椅质量并不达标，正规厂家应该在升降椅的气压杆中充入浓度为99%的氮气，压力在一两个大气压左右，但很多黑心厂家充入的是空气。

Anshan emerging teaching equipment factory Mr Bai is introduced,At present on market to sell a lot of chair lift quality standard is not,Normal manufacturer should be in the chair lift pressure bar in filling the concentration of 99% nitrogen,Pressure in one or two about atmospheric pressure,But many shoddy manufacturer is filling the air.

　　与配件质量有关系吗？答案是肯定的。白先生说，气缸质量越好，越不容易爆炸。反之，气缸壁很薄，在反复升降中难免摩擦受损，容易发生气体外泄，可能导致气压不平衡而爆炸。

And parts quality is relationship?The answer is yes.Mr. Bai said,The quality of the cylinder, the better,The less easy to explosion.and,Cylinder wall is thin,In the repeated lifting is friction damage,Prone to gas leaked,May cause pressure imbalance and explosion.

　　为避免爆炸的危险，白先生建议市民购买正规厂家生产的座椅，切莫贪图便宜购买“三无”产品，他说：“正规的产品，在说明书中都会有使用年限或者使用次数范围，超出范围后安全性就降低了，请大家留意。 ”另外，他建议市民坐在椅子上时，不要频繁升降，以免过多损耗椅子的气压缸和气压棒。椅子升到最高时，气缸内压力最小。但这并不表示调节到最高的椅子不会爆炸。( 辽沈晚报 记者胡宜男 )

In order to avoid the risk of explosion,Mr. Bai proposal citizen purchase normal manufacturer production seat,Never covet is cheap to buy"neutral"products,He said:"Normal products,In the specification will have use fixed number of year or use frequency range,Beyond the scope of the safety was reduced,Please pay attention to. "In addition,He suggested that citizens when sitting on the chair,Don't frequent lifting,In order to avoid too much loss chair pneumatic cylinder and pressure bar.The chair up to the highest,In the cylinder pressure minimum.But that does not mean that adjustment to the highest chair will not explosion.( LiaoShen evening news reporter HuYi male )
