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.
另外，过大的切割速度和过大的喷嘴高度都会引起切口上下宽度差的增加。
In addition, too much cutting speed and big nozzle height can cause and the increase of the poor incision width.
所以，选用尽量小的喷嘴高度对提高切割速度和切割质量都是有益的，但是，喷嘴高度过低时可能会引起双弧现象。
So, choose as far as possible to improve the nozzle of small high cutting speed and cutting quality is useful, but the nozzle at low altitude may cause double arc phenomenon.
采用陶瓷外喷嘴可以将喷嘴高度设为零，即喷口端面直接接触被切割表面，可以获得很好的效果。
Adopt ceramic nozzle can be the nozzle, that is set to zero height vent end direct contact with the surface is cut, can achieve very good result.
喷嘴高度：指喷嘴端面与切割表面的距离，它构成了整个弧长的一部分。
Five, the nozzle height: refers to the nozzle surface and cutting the distance from the end, it constitutes the part of the whole arc long.
所以在切割前要根据材料的厚度正确选用切割电流和相应的喷嘴。
So in before cutting the thickness of the material according to the correct choice of cutting current and the corresponding nozzle.
醇基燃烧喷嘴含有所述气动剪切刀、管式固定座、通气孔、气液疏导管、固定帽和气液切割座。
The alcohol group burning nozzle comprises the pneumatic cutting knife, a tubular fixing seat, an air vent, a gas and liquid conduit, a fixing cap and a gas and liquid cutting seat.
尽管水管运行会影响喷嘴压力，泵也要持续(不能使泵空载，同时启动切割头)输送列出的精确压力。
Although hose operation will affect the nozzle pressure, pump will continue to feed the listed precise pressure (don't make the pump idle and start up the cutting head at the same time).
模型采用三层结构，输入变量有水射流压力、水喷嘴直径、磨料粒子粒度(直径)、磨料流量和切割头进给速度。
Three layers network topology is adopted. The input variables are water pressure, diameter of orifice, diameter of abrasive particles, flow rate of abrasive and feed rate of cutting head respectively.
