The effect of the cutting machine with different gas cutting analysis

Cutting machine processing metal must use auxiliary gases is generally known, auxiliary gas is widely used in the gas is nitrogen, oxygen and air, and air is a gas of economic material benefit, only need a air compressor can enter the air stream.

air cutting machine cutting principle:

cutting machine at the time of processing, must want to use the protective gas, air, of course, is simple and economic protective gas, and the effect of air compressor is part of the compressed air with high purity oxygen and high purity nitrogen gas cutting gas for cutting head, the part as power source supplied to cylinder clamping workbench, after blowing dust removing part of the system is used to light the road, from the air out of the compressed air after gas-holder and dryer after entering pneumatic tank, then through a set of sophisticated processing system, into a clean, dry gas, eventually into three road, respectively as cutting gas cylinder power source, and light way of positive pressure dust gas to maintain the normal operation of the cutting machine, so the air compressor is an essential part of each cutting equipment, is also very important for cutting machine.





the effect of the cutting machine with different gas cutting analysis:

1. Air; Can be provided directly by the air compressor, so compared with other gas price is very cheap. Although containing about 20% of the oxygen in the air, but the cutting efficiency is much less oxygen, cutting ability similar to nitrogen. Cut surface will appear trace oxide film, but can be used as measures to prevent a coating layer falls off. Incision face yellow.

main applicable materials are aluminum, aluminum alloy, stainless copper, brass, galvanized steel, nonmetal and so on.

2, nitrogen; Some of the metal cutting when using oxygen oxidation film formed on the surface of the cutting, using nitrogen gas to prevent the occurrence of the oxide film could be without oxidation cutting. No cut surface oxide can be welding, direct daub, strong corrosion resistance, etc. Incision face pale.

the board that is mainly used with stainless steel, galvanized steel, brass, aluminum, aluminum alloy, etc.

3, oxygen; It is mainly used for cutting machine for cutting the carbon steel. Use oxygen heat of reaction of large-format improve cutting efficiency at the same time, the oxide film can improve the beam spectrum absorption factor of reflective materials. Incision face black or dark yellow.

the main applicable rolling steel, dissolves in rolling steel structure, mechanical structure with carbon steel, high tension, palette, stainless steel, galvanized steel, copper, copper alloy, etc.

cutting machine adopts air cutting, air compressor is a very important auxiliary equipment, of course, although adopts air cutting is no cost, but for the air compressor maintenance or have to pay attention to, this directly affects the purity of the air and air pressure, on the whole have affect the cutting quality. Let's air compressor maintenance steps to share with you:

1, air filter filter. In general every 500 hours to remove dust on the surface of the air filter filter material, check whether need to replace every 2000 hours. Inspection or replacement cycle according to extend or shorten the dustiness.

2, intake valve seal. Want to work at the cutting machine of the air compressor for every 4000 hours, check the sealing ring, to be replaced when necessary.

3, compressor lubricants. To check the oil every 1000 hours, enough to replace the new oil every 4000 hours.

4, oil filter. To replace a new one every 2000 hours.

5, oil vapor separator. Need to replace a new one every 4000 hours.

6, pressure valve. Once every 4000 hours cleaning, and check whether the open pressure is normal.

7, the relief valve. Check whether the action sensitive every 4000 hours.

8, the oil drain valve. Every 2000 hours to discharge water and dirt.

9, drive belt. Every 2000 hours to adjust the firmness, abrasion of checking every 4000 hours, according to the wear condition to decide whether need to change.

10, motor maintenance. According to the motor operating instructions for maintenance.

in order to make the cutting machine of the air compressor can run normally and reliably, and ensure the service life of the unit, must develop detailed maintenance plan, implement during operation, regular maintenance, regular inspection and maintenance, keep the air compressor unit, clean, no oil, no dirt.
