The single screw is a new type of grouting pump that works on the principle of a rotating meshing volumetric type. The main working parts are an eccentric screw (rotor) and a fixed bushing (stator).
Due to the special geometric shapes of the two parts, separate sealed chambers are formed respectively. The medium flows uniformly in the axial direction, the internal flow rate is low, the volume remains unchanged, and the pressure is stable, so turbulence and agitation are not generated. The output pressure of each stage pump is 0.6MPa, the head is 60m (clear water), and the self-priming height is generally 6m. It is suitable for conveying medium temperature below 80°C (up to 150°C for special requirements).
The single screw pump is a product with large grouting volume designed and produced by our factory according to market needs. It can transport a variety of media such as cement slurry, yellow mud, water glass, oil, and water. It has the advantages of compact structure, reliable work, low failure rate, convenient cleaning and maintenance, and high pumping pressure.
It can be widely used for grouting and blocking water in tunnels and mines, grouting for rock tunnels and concrete shaft walls, reinforcement and reinforcement of tunnel cracks, broken rock mass, and evacuated rocks, anchoring grouting, backfill grouting and prevention The ground sinks, prevents landslides, corrects the grouting of the building deflection, etc.
