ZF water sealing device, coal water sealing, a water sealing device price

Function: 1, water into the coal, the release of part of the gas, effectively reducing coal gas content; 2, to achieve the effect of water, dust can be reduced by 80%, improving workers' working environment, to prevent dust explosion; 3, moist coal prevention of spontaneous combustion in coal; 4, high-pressure water, broken coal, reduce fire industrial products, reduce costs and increase workers' sense of security; 5, sealing is broken coal use, can effectively prevent coal and gas outburst and explosion. Third, the structure: sealing rubber expansion consists of a high pressure hose, safety valve, quick coupling components. Fourth, the technical parameters: Sealing diameter: 30-120mm (according to user needs processing) Working Pressure: 1-20MPa (according to user needs processing) safety valve starting pressure: 0.4-0.5MPa Work flow: water per hour 4- 4.5 tons sealing depth: 0.5-8m hose expansion coefficient: 60% -100% Five, the use of methods and precautions: 1, the use of coal seam water sealing is fast and simple. Just the job site connecting waterways and sealing, the sealing device is fully inserted into the borehole, under pressure, to achieve expansion sealing device sealing hose, water breaking coal. 2, seam sealing water can be reused several times after the injection pressure is removed, the sealing device can be recovered, remove the sealing device. 3, sending plug sealing device and recycling with pressure sealing operation is prohibited. 4, the sealing device was not allowed to work the front of the job. Rubber water sealing device Application: coal water, drainage methane gas. Second, the function: 1, water into the coal, the release of part of the gas, effectively reducing coal gas content; 2, to achieve the effect of water, dust can be reduced by 80%, improving workers' working environment, to prevent dust explosion; 3, moist coal body, prevention of spontaneous combustion in coal; 4, using advanced emission drilling plus Face drainage system, the amount of gas emission and discharge drilling cuttings significantly increased play better outburst prevention effect, effectively release stress, gas pressure, to prevent the occurrence of incidents when cutting coal; 5, to solve when cutting coal and gas outburst prevention drilling gauge problem, can effectively prevent coal and gas outburst and explosion. Fourth, the structure: sealing rubber expansion consists of a high pressure hose, middle steel sliding sealing joints and injection pressure fittings components. V. Technical parameters: Sealing diameter: 65-150mm (according to user needs processing) Working Pressure: 1-20MPa (according to user needs processing) Work flow: 5-8 tons of water per hour, depending on the concentration of gas drainage volume and pressure sealing depth: 0.5-3m hose expansion coefficient: 60% -100% in June, using the methods and precautions: 1, the use of gas drainage sealing device quick and easy. Just the job site by sea or air pump and sealing device injection-molded terminal communicates with the intermediate pipe and gas discharge line communication, the sealing device is fully inserted into the borehole, under pressure, sealing hole hose expansion to achieve sealing, drainage water or gas. . 2, gas drainage sealing device can be used repeatedly several times, water or drainage after the gas pressure is removed, the sealing device can be recovered, remove the sealing device. 3, sending plug sealing device and recycling with pressure sealing operation is prohibited.
