hydraulic grout pump

The medium-pressure cement grouting pump features a single-piston, double-acting design with a gear reducer, a compact structure, and is suitable for medium-scale grouting projects such as soil nailing and anchor bolting. Typical applications include:
1. Foundation reinforcement: Injecting cement grout into soft soil foundations to improve bearing capacity and prevent settlement.
2. Tunnels and underground engineering: Used for filling voids behind tunnel linings, reinforcing rock strata, and waterproofing.
3. Slope stabilization: Grouting and reinforcing landslides or unstable rock strata to enhance slope stability.
4. Concrete structure repair: Repairing defects such as cracks and hollow areas to improve structural durability.
5. Water conservancy projects: Construction of dam anti-seepage walls, dam reinforcement, and foundation treatment.

A diesel cement grout injection pump is a device that uses a diesel engine as a power source to inject cement grout or other grouting materials into strata, fissures, or structures. It mainly consists of a power system, a pumping system, a mixing system, and a control system, and features high pressure, large flow rate, and strong adaptability.

A hydraulic high-pressure horizontal cement grouting pump is a specialized device driven by a hydraulic system to inject cement slurry and other readily setting materials into rock formations, soil cracks, or gaps in building structures at high pressure. The core principle is based on hydraulic transmission and the reciprocating motion of a plunger:
Hydraulic drive: An electric motor drives a gear pump, which delivers high-pressure oil through a relief valve and into a hydraulic reversing valve block, controlling the reciprocating motion of the hydraulic cylinder.
Synchronized grouting: The hydraulic cylinder and the working cylinder move synchronously, with suction and discharge valves at each end. This allows for single-liquid or dual-liquid grouting (e.g., a mixture of cement slurry and water glass).
