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).
