Hydraulic Hole Sealing Device for the Coal Seam Water Injection
We have reserched and developed various gas drainage hole sealing devices and hydraulic fracturing hole sealing devices of different working principles and performances and meeting different working environments according to specific requirements of different coal mines, and have obtained Mining Products Safety Label.
Application: water injection for coal, gas drainage
Structure:
The hole sealing device is composed of high pressure rubber expansion hose, middle tube, sliding seal joint and injection pressure connector.
Techncial Parameter:
Sealing diameter: 65-150mm (can be processed according to customer’s requirements)
Working pressure: 1-6Mpa (can be processed according to customer’s requirements)
Start-up pressure of relief valve: 0. 4-0. 5Mpa
Working flow: water injection 5t-8t/h. Gas drainage volume depends on concentration and pressure
Sealing depth: 0. 5m-3m
Hose expansion coefficient: 60%-100%
Operation Guides and Precautions
1 Connect the waterway or airpump on the working site to the injection joint of the hole sealing device, and connect the middle tube to the gas drainage piping. Fully insert the hole sealing device into the borehole. Under certain pressure, the hole sealing device hose expands to realize hole sealing, water injection or gas drainage.
2 The gas drainage hole sealing device can be used repeatedly for serveral times. After water injection, remove the pressure, and the hoel sealing device can get back into shape, then you can take the devie out.
3 It is forbidden to insert and take out the device with pressure.
