high quality!Coal seam water injection hole sealing device FKSS II-38
1,Application:
It is used for coal water injection, dust falling, coal pressure reduction, coal cracking, gas drainage, etc.
2,Function:
1 By injecting water into coal mass, some of the gas can be discharged, thus the gas content of the coal mass can be effectively reduced.
2 If water injection achieves the desired effect, the dust can be redued by more than 80%, thus improving the working environment and avoiding dust explosion accident.
3 It can dampen the coal and prevent spontaneous combustion of coal.
4 It uses high pressure water injection to break the coal mass, so as to reduce fire work products, reduce the cost and improve the security of workers.
5 It breaks the coal with hole sealing device, thus effectively preventing coal and gas outburst and explosion.
3,Structure:
The hole sealing device is composed of high pressure rubber expansion hose, relief valve, and quick connector.
4,Technical Papramenters:
Sealing diameter: 30-120mm (can be processed according to customer’s requirements)
Working pressure: 1-8Mpa(can be processed according to customer’s requirements)
Start-up pressure of relief valve: 0. 4-0. 5Mpa
Working flow: water injection 4t-4.5t/h
Sealing depth:1m-8m
