Water ring vacuum pump in the coal industry applications
Safety of coal mines should start with small things, such as water ring vacuum pump in the coal industry: the safety of coal mines more and more people's attention, an endless stream of accidents continue to require a variety of coal mine safety checks, Water ring vacuum pump as a coal mine machinery products, explosion-proof motor performance and material has strict requirements. Mainly in: 1. Extraction of gas, also known as coal-bed methane, the main component is methane. Open coal seam gas content is quite rich, assuming natural distribution to the air will pose a serious greenhouse effect, but also more serious risk of explosion, every year due to gas explosion to the country and the family caused serious losses, gas safety has become Coal mining industry's most important work. As we all know, water-based vacuum pump as a medium in the whole pumping, exhaust are almost isothermal state, is the extraction of gas such flammable and explosive gases the best equipment. It is noteworthy that, if the extracted gas should be equipped with explosion-proof motor. 2. Dusting Coal mine dust quantity, composition is complex, is the main source of air pollution in the mining area. To large-scale water ring vacuum pump-based pumps, respectively, configuration, dust removal, maintenance and other devices to complete the recovery of mine dust applications, but also played a role in purifying the air. 3. Coal refining In the coal vacuum filtration process, the ordinary implore to withstand the impact of air flow and water air volume water ring vacuum pump, the need to configure the front separate devices to smooth the pressure, respectively, liquid. 4. Vacuum pump monotone cable mine cable in the more humid long-term mine, it is easy to reduce the insulation performance. Water ring vacuum pump pump for the extraction equipment, through the internal low-voltage cables, high current, after the internal heat, in the case of low oxygen concentration to complete the monotonous, effectively prevent the oxidation phenomenon, thus prolonging the aging of the cable process. 5. Consumption of anti-static equipment In the consumption of anti-static, flame retardant conveyor belt and downhole clothing and other products in the process, the vacuum impregnation process, so that anti-static, flame retardant into the conveyor belt to replace the original spraying process, More secure and reliable.
