排烟焊枪具有俘获施焊时产生的有害烟气的功能,有利于环境的空气清洁,因而被广泛应用.排烟焊枪适用于各种大小的工件.可在固定场所或流动场所使用,不象其他排烟装置那样受使用条件的限制.排烟焊枪和普通焊枪的外形一样,.烟气的俘获由一系列围绕在焊枪未端的圆孔管完成.圆孔管的排列和方向根据不同情况而变化,吸入的空气和俘获的烟气通过一个软管来排除,这个软管接在排气系统的支管54上.软管的排气性能(排气量.流速).必须与焊枪上的烟气俘获装置相适度.气体保护传接用的焊枪喷咀,必须确保在任何焊接工况下使熔池不受空气中氧的影响.为了避免焊枪上附加的烟气俘获装置对气体保护区域的影响,需要对这种装置的设计进行研究.
Exhaust torch gun has trapping welding fumes generated when the function of harmful to the environment conducive to air cleaning, which is widely used. Exhaust torch for a variety of sizes of the workpiece. Can be used in fixed or mobile sites, not like Other exhaust devices are subject to the conditions of use. Exhaust gun and general welding torch shape. Flue gas capture by a series of round the end of the torch to complete the round tube arrangement and direction according to different circumstances Varying, the aspirated air and captured flue gas are removed by a hose connected to the exhaust system branch pipe 54. The exhaust performance of the hose (exhaust volume. Flow rate) must be the same as the smoke on the torch Gas capture device compatibility. The torch nozzle for gas-tight transfer must be such that the weld pool is protected from oxygen in the air under any welding conditions. In order to prevent the additional fume capture device on the torch from interfering with the gas protection zone Impact, the design of this device needs to be studied.
