After a lot of practice summary, how to use the cutting nozzle of gasoline cutting machine is not easy to bad, to achieve the best service life, I believe that this is the most concern of many enterprises! Here's a brief analysis of the use of the extension of the gas cutting nozzle:
1,According to the thickness of the cutting workpiece to select the appropriate cutting nozzle.
Such not only guarantee cutting nozzle for optimum performance, but also can guarantee the cutting workpiece kerf width, material saving and gas, oxygen.
2,And gasoline cutting nozzle used normally for 15 days or so, first gasoline cutting mouth nozzle with cutting nozzle coat are separated, with a knife to slice the tooth slot and hole product of ballast cleaning, then the whole cutting nozzle immersion in small bottles of gasoline, to go to work the next day when the cutting nozzle to take out, wash again, so is the a new cutting nozzle.
3, The correct cutting distance, in metal cutting, cutting the distance between the nozzle and the workpiece according to the thickness of the workpiece, maintained at between 3-8mm, otherwise, it is easy to burn out cutting nozzle.
4, When the flame is burning, the fire heart must burn in the nozzle, otherwise easily burn cutting nozzle.
5, To extinguish the flame, when the screw preheating oxygen valve to adjust the flame, old flame to extinguish, is likely to is cutting torch head is not strict. At this time, should remove the cutting nozzle, check cutting torch head cavity and cutting nozzle have no dirt and contact surface is smooth, (not smooth words you can use fine sandpaper grinding research to smooth until closely together) disposal, and the cutting nozzle tighten the lock nut.
6, When preheat flame adjustment is normal, cutting nozzle loudspeaker sound, but the fire is not extinguished, if cutting open the oxygen, flame soon extinguished, the reason is oxygen from the high pressure cavity channeling into the low pressure chamber, the disposal of love with the five. If can not be disposed of after the problem is solved, can be considered in the 45# contact surface water tight tape cutting nozzle and try again.
Generally speaking, the normal service life of a gasoline cutting nozzle for 4 months (every 6 hours monthly according to 26 days) if cutting nozzle of the actual service life of the deviation is too big, please consider according to the above method for correct use of cutting nozzle.
