China Supplier Water Injection Hole Packer for mine industry

      Product Description       China Supplier Water Injection Hole Packer for mine industry  The function of water injection hole packer: It can inject water into the coal bed which can release some gas. So it can reduce the gas content effectively. The dust can be reduced by 80% if the water-flooding effect is good. So it can improve the workers' operation conditions greatly and prevent the dust explosion accident effectively. The water can humidify the coal bed, which can prevent the auto-ignition of the coal. The water is injected in high pressure, which can crush the coal. So it can lessen initiating explosive devices, lower the cost and increase the workers' sense of safety. Breaking coal with water injection hole packer can prevent the explosion of coal and gas effectively. The details of water injection hole packer: Structure: water injection hole packer is composed of high pressure inflation hose, safety value and rapid-acting coupling. And high pressure inflation hose is made from high quality NR synthetic rubber, which is resistant to abrasion, weather, ozone and high pressure. Sealing hole diameter: 25 mm - 155 mm (changeable according to customers' requirements). Working pressure: 1 MPa - 8 MPa (changeable according to customers' requirements). Safety value opening pressure: 0.4 MPa - 0.5 MPa. Working flow: it can inject water 4 t - 5 t per hour. Sealing hole depth: 1 m - 8 m. Hose inflation coefficient: 60% - 100%. Inflatable area: 24 mm - 160 mm. Inner diameter: 10 mm - 102 mm. Outside diameter: 24 mm - 128 mm. Test pressure: 6 MPa - 30 MPa. Burst pressure: 12 MPa - 40 MPa. Specifications of Hole Packer
