气压升降椅,一枚放置在你身边的不定时“炸弹”。我们每天坐在椅子上处理公务、上网、开会,从没有意识到它的危险性。气压升降椅依靠气缸内的活塞气动杆上下活动控制升降,气缸内的填充气体为高压氮气,当内部气压超过气缸的承受限度时会产生爆炸,爆炸时产生的冲击力甚至可以将椅子的零件炸入人的腹腔,严重威胁生命安全。一些厂家生产零件所用的材质硬度不够,并且将内部的填充气体替换为 Air lift chair, a non-time placed on your side “bomb ”. We sit on a chair every day to handle official business, get online, meet, and never realize its dangers. Air lift chair rely on the pneumatic piston rod in the cylinder up and down activities control the lift, the cylinder filling gas is high pressure nitrogen, when the internal pressure exceeds the limit of the cylinder will produce an explosion, the impact of the explosion can even bomb the chair parts Into the abdominal cavity, a serious threat to life safety. Some manufacturers use parts of the material hardness is not enough, and the internal filling gas is replaced by
