气体增压泵在激光切割机中起到什么效果你知道吗?

  激光切割机切割不同的数据使用不同的辅助气体。辅助气体的压力和所需的流量随切削数据的厚度而变化。激光切割气体主要用于引导:激光气体(激光发生器用于激光气体)、压缩空气(通常用于保持光路,一些制造商也用于维护的气体),天然气(也就是说,楼主说启动喷嘴的气体)与氧气切割碳钢,其纯度一般在99.5%或更高。
  Laser cutting machine uses different auxiliary gas to cut different data. The pressure of the auxiliary gas and the required flow rate vary with the thickness of the cutting data. Laser cutting gas is mainly used for guiding: laser gas (laser generator is used for laser gas), compressed air (usually used to maintain the optical path, and some manufacturers are also used for maintenance), natural gas (that is, the gas for starting the nozzle) and oxygen cutting carbon steel, the purity of which is generally 99.5% or higher.
  其主要作用是助燃和吹走熔融物质。激光切割靴制造商的压力和流量是不同的,这与切割喷嘴的大小、切割数据板的厚度密切相关。压力一般要求在0.3-0.8mpa,切嘴一般为0.02-0.05Mpa。流量不易说出口,如切割22mm碳钢,有的厂家要达到10M3/h流量(包括双切割喷嘴维护氧气)。

  Its main function is to support combustion and blow away molten materials. The pressure and flow rate of laser cutting shoe manufacturers are different, which is closely related to the size of cutting nozzle and the thickness of cutting data plate. The pressure is generally 0.3-0.8mpa, and the cutting nozzle is generally 0.02-0.05mpa. It is not easy to say the outlet flow, such as cutting 22mm carbon steel, some manufacturers need to achieve 10m3 / h flow (including double cutting nozzle maintenance oxygen).
  氮是用来切割不锈钢的。其效果是消除氧化反应,吹走熔体。氮纯度有较高的要求(特别是8mm以上的不锈钢,一般要求达到99.999%以上的纯度),压力要求相对较大,一般要求1Mpa,如切割12mm以上,或较厚至25mm的不锈钢,压力要求较高,超过2Mpa或更高。根据切割喷嘴的类型有一些变化,但是变化非常大,比如有些厂家切割12mm不锈钢到150m3/h,切割3mm,只有流量低于50m3/h。
  Nitrogen is used to cut stainless steel. The effect is to eliminate the oxidation reaction and blow away the melt. The nitrogen purity has higher requirements (especially for stainless steel of 8mm or above, it is generally required to reach 99.999% or above), and the pressure requirements are relatively large. Generally, 1MPa is required, such as cutting stainless steel of 12mm or above, or thicker to 25mm, the pressure requirements are higher, more than 2MPa or higher. According to the type of cutting nozzle, there are some changes, but the changes are very large, for example, some manufacturers cut 12mm stainless steel to 150m3 / h, Cut 3mm, only the flow rate is less than 50m3 / h.
  在激光切割过程中,辅助气体必须有一个满意的压力,才能彻底清除切割产生的废渣。一般情况下,切割较厚的工件时,应降低压力,而残留在工件上的残渣会破坏切削刃。加气压力可以提高切割速度,但达到后,连续加气压力会导致切割速度下降。
  In the laser cutting process, the auxiliary gas must have a satisfactory pressure to completely remove the waste generated by cutting. In general, when cutting thick workpieces, the pressure should be reduced, and the residue on the workpieces will damage the cutting edge. The gas pressure can improve the cutting speed, but when it reaches the maximum, the continuous gas pressure will reduce the cutting speed.
  下辅助气体压力高,切割速度下降的原因可以归因于增强冷却效果的高挂的气流速度和冷却效果影响区,它也可能是间歇性的扰动气流的激波区激光冷却效果。气流中的压力和温度不均匀,会引起气流场密度的变化。这样的密度梯度导致场的折射率改变,然后光束的能量积累、重新聚集或发散。
  The reason for the high pressure of the lower auxiliary gas and the decrease of the cutting speed can be attributed to the high hanging air speed and the cooling effect influence area which enhance the cooling effect, and it may also be the laser cooling effect of the shock wave area which intermittently disturbs the air flow. The uneven pressure and temperature in the air flow will cause the change of air field density. Such a density gradient causes the refractive index of the field to change, and then the energy of the beam accumulates, regroups or diverges.
  这种扰动会影响熔化能力,有时会改变形状结构,如果光束偏离太远,会导致切割质量下降。如果斑点太大,甚至会导致严重的后果,不能有效地削减。相应的三种增压方式可以根据压差的不同而有不同的介质方案。
  This kind of disturbance will affect the melting ability and sometimes change the shape and structure. If the beam deviates too far, the cutting quality will be reduced. If the spots are too large, they will even lead to serious consequences and cannot be effectively reduced. The corresponding three pressurization methods can have different media schemes according to different pressure differences.
  空气充电电压输出,基本是保持流动的空气压力用于激光切割在0.6 - 1.5 Mpa在这种情况下,DTE02空气增压系统设备,如原始气压0.8 Mpa,增压压力可达2 Mpa。如果经过减压阀和减压阀来使用压力、喷嘴类型、流量不足的话,可以用DTE02增压泵来增压。
  The output of air charging voltage is basically to maintain the flowing air pressure for laser cutting at 0.6 - 1.5 MPa. In this case, Shandong Xinnuo dte02 air pressurization system equipment, such as the original air pressure of 0.8 MPa, pressurization pressure up to 2 MPa. If the pressure, nozzle type and flow are insufficient through the pressure reducing valve and pressure reducing valve, dte02 booster pump can be used for boosting.
  所需氧气和氮气的纯度气体不能减少,我们可以使用xinuo DTE02气体增压系统(这增压系统可以加压介质的压力增加到1.6 mpa的压力驱动下0.8 mpa),及其增压缸增压过程的独立操作不会导致纯度降低,二次污染。
  The purity gas of oxygen and nitrogen required cannot be reduced. We can use Xinuo dte02 gas pressurization system (this pressurization system can increase the pressure of the pressurized medium to 0.8 MPa driven by 1.6 MPa pressure), and the independent operation of the pressurization process of the pressurization cylinder will not lead to low purity and secondary pollution.
