20-50L/Min Mining Pneumatic Injection Pump With 2 Cylinders

High Quality Mining Pneumatic Injection Pump

Working Principle of Pneumatic Injection Pump

The compressed air enters the cylinder through the ball valve, the air source duo, and the two-position five-way reversing valve, and pushes the cylinder piston to reciprocate. Because the cylinder tie rod is connected with the pulp cylinder tie rod, the reciprocating motion of the cylinder piston also pushes the pulp cylinder piston to reciprocate to complete the suction and discharge action. The reversing is performed by the dial installed on the cylinder tie rod, and the stroke valve is toggled back and forth to control the reversing valve to change the direction of the intake and exhaust of the cylinder, and continuously complete the reciprocating motion of the cylinder piston.

Technical Parameter of Mining Pneumatic Grouting Pump

Advantages of Pneumatic Injection Pump

1. The resistance pump for mines is small in size, light in weight, and easy to transport and carry, especially for areas where the natural conditions in the underground are poor, the equipment and personnel are inconvenient to operate, and it is difficult to transport into larger equipment.
2. Residual coal injection can be sprayed with atomizing nozzles, and it only needs 2-3 people and a mine car to carry the chemical inhibitor solution to work, suppressing the spontaneous combustion of coal, it is a rare small, lightweight, Economical, practical and standing fire protection equipment. 

Application of Pneumatic grouting​ Pump

1. Pneumatic grouting pumps are mainly used in coal mines, iron mines, and other shaft wall waterproofing, and reinforcement grouting projects, as well as grouting water, blocking, and grouting consolidation projects in broken rock formations such as subways, tunnels, water conservancy, and buildings.
It can also be used for pre-grouting of the working face suitable for good depth. The pump can be used for single-liquid grouting (cement slurry), can also be used for double-liquid grouting (cement slurry, water glass), and can also be used to transport other kinds of slurries and clean water that are not too viscous or corrosive. The pump can be adjusted stepless, can also be automatically variable at constant pressure, and has a double-liquid grouting function with a slurry ratio of 1:1.
