Water ring vacuum pump used in coal industry

With the increasing attention to coal mine safety, the water-ring vacuum pump used in coal mine will also put forward higher requirements and standards. Efficient, fast and thorough is the main development direction of annular vacuum pump for coal mine. Next we will understand the application of a water ring vacuum pump in the coal industry, hoping to help you.

1. Coal making

In the vacuum filtration process of refined coal, it is generally required to be able to withstand the impact of air flow and water on the air flow water ring vacuum pump, which needs to be equipped with a pre-separator to stabilize the pressure to separate the liquid.

2, dust removal

Large amount of dust and complex components are the main sources of surface pollution in mining area. With large water-ring vacuum pump as the main pump, equipped with separation, dust removal, protection and other devices to achieve dust recovery and utilization in mining areas, but also played a role in purifying the air.

3. Production of antistatic equipment

In the process of producing anti-static and flame-retardant conveyor belts and underground clothes, vacuum slurry immersion process is adopted to make anti-static and flame-retardant agent enter the conveyor belts instead of the original spraying process, which is more safe and reliable.

4. Vacuum pump drying cable

Mine cable in a relatively humid mine for a long time, it is easy to reduce insulation performance. The water-ring vacuum pump is used as the pumping equipment. The cable is connected with low voltage and high current, which generates heat through the cable and dries under the condition of low oxygen concentration. The oxidation phenomenon is effectively prevented and the aging process of the cable is prolonged.

5. Gas extraction

Gas, also known as coal-bed methane, is mainly composed of methane. The underground coal seam gas content is quite rich, if the natural emission into the air will cause serious greenhouse effect, more serious is that there will be explosion danger, every year because of gas explosion to bring serious losses to the family, gas discharge has become an important job in the coal industry. As we all know, water-ring vacuum pump is an equipment for extracting flammable and explosive gases such as gas, because water is used as the medium in the whole pumping and exhausting almost isothermal state. It is worth noting that if the gas extraction should be equipped with explosion-proof motor.vacuum-equipments
