Jinyuan teach you how to choose the air compressor for laser cutting

1.Two stage intake filtration system in series

Inlet air filter is the key component of the stable operation of screw air compressor. There is a lot of metal cutting dust in the laser cutting environment. When the air filter element is attached to a large amount of metal dust, it will produce deformation with the suction increase of the screw host. At this time, a large amount of metal dust is inhaled into the screw host with the air, resulting in the host and bearing wear, seriously affecting the service life of the screw air compressor. In view of this problem, we should choose the laser air compressor, choose the series 2-stage air intake filtration system, let the inhaled air filtration for two times, effectively reduce the risk of metal dust being inhaled.

2.The permanent magnet motor adopts the high protection grade of IP55

There is a lot of metal cutting dust in the laser cutting environment. Most of the supporting laser air compressors on the market use IP23 motor protection grade, and the gap between the motor rotor and the stator (air gap) is directly connected with the atmosphere. Because the motor rotor is a permanent magnet, the metal dust in the air will attach to the surface of the rotor after entering the motor. When the metal dust accumulates to a certain thickness, it will friction with the stator, leading to the direct burning of the motor. In view of this problem, we choose the laser air compressor should choose a high protection level of the motor, the motor using IP55 closed motor, the heat is dissipated by the motor housing heat sink.

3.The screw host adopts 6 pairs of SKF bearings, heavy load type

The maximum use pressure of the air compressor for laser cutting is 16 bar, which is nearly 2 times more powerful than the conventional 8 bar air compressor. Many in the market follow the consistent practice of low load 8 bar, using 4 pairs of bearings, and the motor is integrated without independent bearing support. The force of the whole motor depends on the 4 pairs of bearings of the screw engine, which seriously affects the service life of the screw engine. So when we choose the laser air compressor, we should choose 6 pairs of imported bearing screw host, and the motor is a split-type structure, with independent bearing support.

4.High efficiency and energy saving, large displacement

Air compressor is a big energy consumer. Take the 15KW laser air compressor as an example, if the air compressor is always used at full load, the power consumption per hour is 15 kWh. If a year presses 8000 hours average electricity price presses 1 yuan calculation, the electricity charge that uses every year is 120 thousand. Our energy-saving air compressor has nearly 25% energy saving rate, that is, can save electricity about 30,000 yuan every year.(Example: use one of our 15KW laser air compressor, can take two 3KW laser cutting machine.）

5.Patent water-removal structure design (unique)

Due to the high compression ratio of the laser cutting air compressor, the water molecules in the air are compressed with the air. If the liquid water is not vaporized, it will emulsify with the lubricating oil of the screw air compressor. In serious cases, the screw air compressor screw host will be hugged, and the whole screw host will be overhauled. Our patented water removal structure has 3 weights of protection, so that the screw air compressor can operate stably for a long time.

6.High temperature, high pressure resistant oil viewing lens

The air compressor for laser cutting is in the high temperature and high pressure operating environment for a long time. The commonly used oil level lens in the market adopts the general parts of the conventional 8 bar screw air compressor and the acrylic material. The life of the laser air compressor is about 2 years. If not replaced in time, it will cause oil mirror rupture and oil leakage. In serious cases, all the oil of the whole machine will run away, affecting the production.

7.High-matching frequency converter, stable operation

Our screw air compressor standard with Inovance frequency converter, stable and reliable operation.

8.Italy imported control valve parts and grade 5 precision filtration system

The high-end configuration ensures the stable operation of the system, and the precision filtration system provides pure compressed air to the laser cutting machine.

9.Air tank is a special equipment, safety first

Due to the pressure of air compressor for laser cutting is 16 bar, the air tank cannot be designed in a conventional 8bar mode. Because most of the air compressor is placed next to the laser cutting machine, the market is a lot of air tank design only pressure 15.8bar, there is a very big safety risk! The pressure that we design is 24.8bar, using pressure is 19.8bar, belongs to the standard class II container.
