The application of water ring vacuum pump in coal mine industry

The safety of coal mines should be grasped from trivial matters, such as the application of water ring vacuum pump in the coal industry:


Coal mine safety problem more and more get the attention of the people, there are plenty of accidents happen, strictly control requirements on coal mine safety performance, water ring vacuum pump as the production of coal mine machinery products, explosion-proof performance of the motor and materials have strict requirements. My company's vacuum pump equipment (gas drainage pump), its configuration professional and specialized gradually, to better meet the needs of coal industry safety in production, efficient, fast, safe is the future of coal mine water ring vacuum pump of the main direction. Therefore, when targeting the special industry of coal mine, our company will have technical backbone to form a research team, focusing on type selection and analysis.

Mainly manifested in:


1. Gas extraction:


Gas, also known as coal-bed methane, is mainly composed of methane. Open coal bed gas content is quite rich, assumes that natural distribution into the air would pose a serious greenhouse effect, is more serious is that will attack the explosion risk, every year because of the gas explosion brought serious damage to the nation, and family, coal gas safety discharge has become the most important work. As is known to all, the water ring vacuum pump is the best equipment for extracting inflammable and explosive gases such as gas because of its almost isothermal extraction and exhaust with water as the medium. It is worth noting that if gas extraction should be equipped with explosion - proof motor.


2. The dust removal:


The quantity of dust in coal mine area is large and the composition is complex, which is the main source of air pollution in mining area. The large water ring vacuum pump is used as the main pump, and the equipment such as dedusting, dedusting and maintenance is equipped to complete the dust recovery application in the mining area, which also plays the role of purifying the air.


3. The artificial coal:


In the process of vacuum filtration of refined coal, the general supplication is to withstand the impact of air flow and water.


4. Vacuum pump monotonic cable:


Mine cable in the relatively damp mine for a long time, it is easy to reduce the insulation performance. Water ring vacuum pump as the extraction equipment, inside the cable is connected to low voltage, high current, after internal heat, in the case of low oxygen concentration complete drab, effectively prevent the oxidation phenomenon, so as to prolong the aging process of cable.


5. Consumption of anti-static equipment:


Walked in the consumption of antistatic, flame retardant belt and the process of downhole products such as clothing, the leaching pulp vacuum technology, antistatic, flame retardant into walks with internal, instead of spraying process, more safe and reliable.


Configuring security, high reliability: the 2 be series water ring pump matching specially designed for the gas separator, and related instrument consisting of a vacuum - compressor unit, ensure the pumping gas gas leak. Due to the use of water or other liquids as working fluid, it can take away the heat of compression, followed by isothermal compression process, especially suitable for the extraction and pressure delivery of inflammable and explosive gases.


Has characteristics of explosion-proof itself: in order to comply with the demand of coal industry safe consumption, more professional service in the coal industry, water ring vacuum pump design itself to extinguish the flame characteristics, so the use of water ring vacuum pump as the gas drainage and walks, dispense with explosion-proof equipment, this advantage is very obvious, mainly displays in: (1) the equipment to reduce; (2) save water; (3) reduce the monitoring point; (4) complete explosion-proof characteristics.


Patented one-way valve in the suction mouth of the vacuum pump and vacuum system, when there are abnormal downtime, can complete automatically switched systems and the access of the vacuum pump, have the effect that prevent backwater, prevent tempering.


The individuation characteristic is obvious: according to the request of mine gas overlimit and safety consumption of coal and gas outburst, the development and consumption of Marine gas drainage pump can effectively deal with the above problems. The moving pump is mainly composed of the pumping system, the monitoring control system, the inlet and outlet airway, and the moving pump base frame, shell and wheel.


The main features of the gas pump are:


1. Small size and sensitive movement;


2. Perfect maintenance measures;


3. Special requirements suitable for underground coal mines;


4. The gas containing a large amount of water vapor and small solid particles can be pumped out to be stronger.
