ZHJ mining mobile fire-fighting grouting device is an important coal mine fire prevention grouting equipment, have convenient to move, connect a simple, quick, applicable in extinguishing grouting materials widely, grouting cost low characteristic, can meet different types of underground coal spontaneous combustion fire and use different slurry materials for fire prevention of the prevention and control of spontaneous combustion needs.
The main technical indexes:
1) with single screw pump, metering pump and mixer component of the underground grouting pump adopts the power transmission, suitable for long-distance transmission of yellow mud, fly ash, glue pulp extinguishing material infusion and coal goaf wall fracture zones, and coal wall fracture and high temperature points such as the drill perfusion plugging fire prevention or spontaneous combustion disasters processing.
The rated flow: 3, 6 m3 / h
Pressure rated: 2 ~ 5 MPa
Fire extinguishing material conveying slurry concentration: 60% or less (volume content)
Fire slurry materials containing solid particles diameter: more than 8 mm
2) ever after pump, metering pump and store up of material box underground grouting pump adopts the power transmission, mainly is suitable for the close conveying steam fog resistance, agents, nitrogen foam, gel, wong nei daub, fire fighting materials perfusion coal wall fracture zones and high take, used to put out happened in support of the top or high risk of spontaneous combustion with local fire.
Steam injection fog resistance, agents flow: 400 L/h
Note: 3.4 m3 / gel flow h
Note nitrogen gas bubble fluid flow: 3 m3 / h (high with low degree of bubble)
Note wong nei daub maximum flow: 50 m3 / h (add the accelerating)
3) the integration of double screw pump light with light weight, small size, high reliability, electricity (gas) move two drive mode and other characteristics, can meet mine perfusion gel extinguishing the need of quick flexible operation
