Generally, there will be some pollution when using the equipment. So what are these pollutions? The following editor will talk about the pollution generated by the plasma cutting machine at work:
1. Prevention methods of arc light radiation: Arc light radiation is mainly infrared radiation and visible light radiation. The operator must wear a mask and gloves to protect the face, hands and neck. Masks are best protected with lenses. When cutting, you can use the water cutting method to use water to absorb light radiation.
2, dust and dust prevention methods: large gas flow during cutting, a large amount of vaporized metal vapor, ozone, nitrides, etc. during the cutting process. Causes a lot of dust to rise. Therefore, good ventilation equipment must be provided and dustproof measures must be taken. When cutting, an air exhaust device can also be placed under the grid table, or a water cutting method can be used to reduce dust.
3, electromagnetic field prevention methods: high-frequency electromagnetic harm to the human body. The preventive measures are mainly: the frequency of the pilot arc is more suitable to choose from 20 to 60Hz, the high frequency oscillator is equipped with a shielding cover, the workpiece must be well grounded; when the main arc is ignited, the power of the high frequency oscillator should be cut off immediately; When using high-frequency sparks to check electrode alignment, minimize the time.
4, electric shock prevention methods: manual operation, there is a danger of electric shock. Therefore, the power supply must be well grounded during use, and the torch and hand touching parts must be reliably insulated. The exposed rubber sleeve must be placed on the exposed switch to avoid direct contact with the hand.
5. Noise prevention method: CNC plasma cutting machine will produce high-intensity and high-frequency noise during arc cutting. Automatic cutting should be used as much as possible, and the operator works in the sound insulation room. The method of cutting in water and using water to absorb noise can also be used. In addition, the use of water curtain cutting torch can also greatly reduce the noise.
