Liquid Ring Pump for Mining Industry

The safety of coal mine should start from small matters, such as the application of liquid ring vacuum pump in coal mine industry:

The application of liquid ring vacuum pump in coal mine industry has attracted more and more people’s attention on the safety of coal mine. Increasing accidents have occurred, which require strict control over the safety performance of coal mine. As a mechanical product produced by coal mine, liquid ring vacuum pump has strict requirements on the explosion-proof performance and material of motor. Seek. Our company’s vacuum pump equipment gas drainage pumps and their configuration are gradually specialized and complete, to better meet the needs of coal industry safety production, high efficiency, fast, safe is the main direction of development of coal mine liquid ring vacuum pumps in the future. Therefore, in view of the special industry of coal mine, our company will have a research team composed of technical backbone, focusing on type selection and analysis.

The main manifestations are as follows:

1. Gas extraction

Liquid ring vacuum pump is used in coal mine industry. Gas is also known as coalbed methane, the main component of which is methane. Open coal seam gas content is quite abundant, assuming that natural distribution to the air will constitute a serious greenhouse effect, and even more serious is the risk of explosion. Every year, because gas explosion brings serious losses to the country and families, gas safety discharge has become the most important work of the coal industry. As we all know, liquid ring vacuum pump is the best equipment to extract flammable and explosive gases such as gas, because it uses water as medium in the whole pumping and exhausting process. It is worth noting that if gas extraction should be equipped with explosion-proof motor.

2. Dust removal

The amount of dust in coal mine area is large and its composition is complex, which is the main source of air pollution in coal mine area. Large liquid ring vacuum pump is used as the main pump, equipped with separate, dust removal, maintenance and other devices to complete the dust recovery application in mining area, and also plays a role in purifying air.

3. Coal-making

In the process of vacuum filtration of refined coal, liquid ring vacuum pump with air flow and water impact is usually required to be equipped with a pre-separator to stabilize the pressure and separate the liquids.

4. Vacuum pump monotonous cable

The insulation performance of mine cables can be easily reduced in damp mines for a long time. With liquid ring vacuum pump as pumping equipment, low voltage and high current are used inside the cable to generate heat and complete monotony under the condition of low oxygen concentration, which effectively prevents oxidation and prolongs the aging process of the cable.

5. Consumption of antistatic equipment

In the process of consuming anti-static, flame-retardant conveyor belts and underground clothing, vacuum slurry process is adopted to make anti-static and flame-retardant enter the conveyor belts, replacing the original spraying process, which is more safe and reliable.

Dust removal coal mine area is the main source of air pollution due to its large amount of dust and complex composition. Large liquid ring vacuum pump is used as the main pump, equipped with separate, dust removal, maintenance and other devices to complete the dust recovery application in mining area, and also plays a role in purifying air.

In the process of vacuum filtration of refined coal, liquid ring vacuum pumps with air flow and water impact are usually required to be equipped with pre-separators to stabilize pressure and separate liquids. Vacuum pump monotonous cable mine cable in wet mine for a long time, it is easy to reduce the insulation performance. With liquid ring vacuum pump as pumping equipment, low voltage and high current are used inside the cable to generate heat and complete monotony under the condition of low oxygen concentration, which effectively prevents oxidation and prolongs the aging process of the cable. In the process of consuming anti-static, flame-retardant conveyor belts and underground clothing, the consumption of anti-static equipment adopts vacuum grouting technology to make anti-static and flame-retardant enter the conveyor belts and replace the original spraying technology, which is more safe and reliable. Liquid ring vacuum pump is applied in coal mine industry. A series of water-ring pumps are equipped with a gas separator specially designed for it and a vacuum compressor set composed of related instruments to ensure that the gas pumped is leak-free. Because water or other liquids are used as working fluids, the heat of compression can be taken away and the isothermal compression process can be connected.

It is especially suitable for the extraction and pressing of flammable and explosive gases, which has its own explosion-proof characteristics. In order to meet the demand of safe consumption in coal industry and serve the coal industry more professionally, the design of liquid ring vacuum pump has its own characteristics. Because of the characteristics of extinguishing fire seedlings, liquid ring vacuum pump is used as gas drainage and transmission, which saves explosion-proof equipment and so on. This advantage is obvious, mainly manifested in:

(1) Reduction of equipment
(2) Water saving
(3) Reduction of monitoring points
(4) Complete explosion-proof characteristics.

The one-way vacuum valve with patent technology is placed between the suction port and the system of the vacuum pump. When there is abnormal shutdown, the system and the path of the vacuum pump can be completely and automatically switched. It has the function of backwater and temper prevention. Individualized characteristics are obvious: in view of the request of safe consumption of mine gas exceeding the limit and coal and gas outburst, shipping gas is developed and consumed.
