How to avoid explosion accidents in the use of fiber laser cutting machine?

When it comes to the use of fiber laser cutting machine, everyone should know that it is not very simple. In many cases, if you do not pay attention to it, it is very prone to accidents, so the editor recommends that you must not ignore some safety Precautions. Let's take a look at how to prevent the fiber laser cutting machine from exploding.

The fiber laser cutting machine adopts gas welding and flame cutting technology. The gas and oxygen or air are mixed in the torch through the proportion of the relevant combustion gas. The temperature of the generated flame is sufficient to fuse the relevant surface or cut Time is sufficient to produce molten oxides of the relevant metals.

However, because the working process of the fiber laser cutting machine involves the use of flammable and explosive gas, in the daily operation process, it is especially necessary for the operator to pay attention to the safety protection of the equipment. Among them, the fiber laser cutting machine supplies gas System failure or hot molten slag generated during use can cause dangerous situations such as fire and explosion. In addition, the toxic smoke and radiation generated during the process can also endanger health.

It aims to enumerate the safe working methods of gas welding and flame cutting with oxygen-acetylene (oxyacetylene for short, commonly known as wind coal) flame. It is also applicable to the use of other fuel gas such as propane (generally known as petroleum gas or 'LPG') ) And hydrogen and other flame welding or cutting work, to provide general guidelines for proprietors, managers, safety personnel and supervisors of industrial operations to protect workers from encountering dangers during gas welding and flame cutting, and to reduce fire alarms. And the casualties and losses caused by the explosion.

The fire and explosion hazards of fiber laser cutting machines are mainly caused by gas welding and flame cutting, mainly due to failure of the gas supply system, or due to the high temperature of the flame or hot molten slag. These hazards include:

1. Leakage of flammable gas or oxygen causes fire and explosion. These gases can leak from the joints of the gas supply system, the connection points of the gas hoses, or the gaps in the fittings;

2. Before ignition, the air in the gas hose is not completely discharged, or the gas flows back into the oxygen hose or oxygen flows back to the gas hose, causing the blowpipe to flash back;

3. The blowpipe is tempered, or the acetylene cylinder is overheated, so that the acetylene decomposes or is detonated in the absence of oxygen or air;

4. High-pressure oxygen (in the absence of gas) promotes the combustion of certain materials, such as grease, lubricating oil, organic matter, aluminum metal and its alloys, and elastomers used for valve gaskets and sealing rings;

5. The flame of the blowpipe, the hot surface of the workpiece, or the slag generated during the process burns flammable or combustible materials near the construction site and causes a fire.

This is an introduction to the specific preventive measures for explosion accidents during the operation of the fiber laser cutting machine. I hope it will be helpful to everyone.
