用球面压缩喷嘴取代常规的锥形压缩喷嘴,这些是设计反极性弱等离子弧粉末堆焊枪的关键所在。
Substituting double electrode for normal tungsten and substituting spherical constricting nozzle for normal cone one are the key to design the torch.
这个能量释放的不平衡,与很多工艺参数密切相关,如等离子弧压缩程度、切割速度及喷嘴到工件的距离等。
This energy release imbalance, closely related with many process parameters, such as plasma arc compression degree, cutting speed and nozzle to the distance, etc.
需要压缩空气的应用都可使用空气喷嘴。
An air nozzle can be used in any instance where compressed air is required for an application.
But you don't compress it so quickly that you're not in there reversible process so you compress that if you were to feel the temperature of the air and you can feel it through the nozzle gives you an idea of the temperature of the air inside your bicycle pump.
但是压缩速度,也不能太快,否则就不是,可逆过程了,这样当压缩气体时,从喷嘴可以感受到,内部气体的温度。
