liquid ring vacuum pump in coal mine industry of application

The safety of coal mines should start from small things, such as the application of liquid ring vacuum pumps in the coal industry:

Liquid ring vacuum pumps are used in the coal mine industry. The safety of coal mines has received more and more attention. An endless stream of accidents do not occur. It is required to strictly control the various safety performance of coal mines. Liquid ring vacuum pumps are used as coal mine production. The mechanical products have strict requirements on the explosion-proof performance and material of the motor.

EVP company’s liquid ring vacuum pump equipment and its configuration are gradually specialized and complete, to better meet the needs of safe production in the coal industry. High efficiency, speed and safety are the main development directions of coal mine water ring vacuum pumps in the future. Therefore, when our company focuses on the special industry of coal mines, there will be technical backbones to form a research team, focusing on type selection and analysis mainly in:

1.Extract Gas

Liquid ring vacuum pumps are used in coal mine industry. Gas is also known as coalbed methane, and its main component is methane. It is disclosed that the gas content of coal seams is quite rich. Natural distribution into the air will constitute a serious greenhouse effect, and even more serious is the risk of explosion. Every year, gas explosions bring serious losses to national households, and safe gas discharge has become a coal mine The most important job of the industry. As we all know, the water ring vacuum pump is almost isothermal in the whole pumping and exhausting due to the use of water as the medium. It is the best equipment for extracting flammable and explosive gases such as gas. It is worth noting that if the gas is extracted, explosion-proof motors should be equipped.

2 Dust removal

The large amount and complex composition of dust in coal mining areas are the main source of air pollution in mining areas. A large-scale water ring vacuum pump is used as the main pump, equipped with separate, dust removal, maintenance and other devices to complete the recovery and application of dust in the mining area, and also play a role in purifying the air.

3 Coal smelting

In the vacuum filtration process of refined coal, it is generally required to be able to withstand the impact of airflow and water. Atmospheric water ring vacuum pumps are required to be equipped with a front separator to separate liquids with a stable pressure.

4 Monotonic cable for vacuum pump

Mine cables are easy to reduce the insulation performance in relatively humid mines for a long time. The liquid ring vacuum pump is the pumping equipment. Low voltage and large current are passed inside the cable, and heat is generated inside the cable. It is monotonous when the oxygen concentration is low, which effectively prevents the oxidation phenomenon and prolongs the aging process of the cable.

5 Anti-static equipment

In the process of producing anti-static and flame-retardant transport belts and underground clothing and other products, the vacuum slurry process is adopted to make anti-static and flame retardant enter the inside of the transport belt, replacing the original spraying process, making it safer and more reliable.

Liquid ring vacuum pumps are used in the coal industry. The 2BE series water ring pumps are equipped with a specially designed gas separator and a vacuum-compressor unit composed of related instruments to ensure that the pumped gas does not leak. Since water or other liquids are used as the working fluid, the heat of compression can be taken away, and the isothermal compression process can be connected. It is especially suitable for the extraction and pressure delivery of easy-to-flame and explosive gases. It has the characteristics of its own explosion-proof: in order to meet the needs of safe consumption in the coal industry, and to serve the coal industry more professionally, the water ring vacuum pump design has its own characteristics of extinguishing fire sprouts, so the water ring vacuum pump is used as gas drainage and transportation, which saves you The advantages of explosion-proof devices and other equipment are very obvious, mainly in:

(1) Equipment reduction: (2) Water saving: (3) Reduced monitoring points: (4) Complete explosion-proof characteristics.

The main components of the system include: Vacuum pump/compressor, gas-liquid separator, heat exchanger, Basplate, internal pipelines. Customers can choose the equipment, accessories, measurement and control instruments, switchgear, electronic control devices, etc. base on their requirement.
The level meter of gas-liquid separator can use magnetic flap type, the control can be realized by electric magnetic valve or mechanical high-low level switch, with DCS interface, safe and reliable;
The vacuum pump unit is equipped with working fluid drainage pipeline. When the unit is stopped to use, the accumulated fluid in the unit can be drained to the designated place according to the requirement of environmental protection.
When the temperature of the gas pumped is too high, by adding a spray pipe, the gas is cooled and contracted before entering the pump, indirectly increasing the pump pumping capacity.
