Working environment of explosion-proof air compressor

Conclusion: Explosion-proof air compressor is mainly used in places with flammable and explosive gas or dust, such as chemical workshop, petroleum refining, pharmaceutical factory, flour processing factory, coal mine underground. The core requirement is one, the machine can not produce any sparks or high temperature surface during operation, otherwise it may explode when encountering combustible gas.

There are several specific environmental requirements.

The first is better ventilation. Even if the machine itself does not produce sparks, if the concentration of combustible gas in the surrounding air is too high, if there is any accidental ignition, something will happen. Therefore, the installation place must have continuous ventilation to take away the combustible gas that may leak in time.

The second is to control the temperature and humidity. If the environment is too hot, the surface temperature of the machine will increase, increasing the risk. Too much humidity is easy to produce static electricity, static electricity is also a source of ignition. Therefore, the general requirements of the environment is dry, the ground to do anti-static treatment.

The third is that the electrical part must be explosion-proof. Motors, switches, junction boxes, these components should have a special explosion-proof shell, the internal possible arc completely sealed, not to let it contact with the outside of the combustible gas.

Water-lubricated air compressors have more advantages in this environment. When it works, it uses water instead of oil to lubricate and seal, and there is no oil mist during compression. The gas discharged from the traditional oil-injected air compressor carries oil mist, which is a great hidden danger in the explosion-proof area. The water lubricated air compressor discharges water vapor instead of oil mist, which reduces the ignition risk from the root. Moreover, the cooling effect of water is good, the overall temperature of the machine is lower, and the surface is not easy to overheat. In the explosion-proof area, the water-lubricated air compressor is equipped with an explosion-proof electrical control system, and the safety is higher than that of the oil injection machine.

During installation, it should also be noted that the water pipes and drain pipes of the water-lubricated air compressor should be sealed, and the water should not leak to the electrical components, otherwise it will cause a short circuit. The drain outlet is connected to a safe place, and do not let the water flow to a low-lying place where combustible gas accumulates.

Simply put, the environmental core of explosion-proof air compressor is to eliminate all ignition sources. Water lubricated air compressor is naturally more suitable for this dangerous environment than oil injection machine because there is no oil.
