Hydraulic Intensifier Pump

Converting Low-Pressure Systems to High-Pressure Output

Development headings often rely on roadheaders or roof bolters that provide hydraulic pressure between 20 MPa and 32 MPa. However, cable bolt tensioning typically requires 63 MPa. The Hydraulic Intensifier Pump bridges this pressure gap. By connecting directly to the existing low-pressure hydraulic lines, it uses a planetary gear motor to boost the fluid pressure locally. It converts the host machine's power into high-pressure output, relying entirely on the available fluid network rather than separate power sources.

Feature 1: The unit requires no extra electrical cables or compressed air lines. It connects to hydraulic lines operating between 7 MPa and 32 MPa, making it suitable for gassy environments where electricity is restricted.

Feature 2: The planetary gear hydraulic motor provides high torque and smooth operation. The intensification process is continuous without pulsation, delivering a 2.0 L/min flow rate to ensure steady jack advancement.

Feature 3: The compact design allows it to mount directly onto existing pipework using quick couplings. It travels with the roadheader or drilling rig, enabling immediate tensioning as the machine moves along the face.

When mounted on a roadheader or bolter, the Hydraulic Intensifier Pump applies tension immediately after installation, tracking the excavation progress. On coal faces, it can connect to the emulsion lines operating at 20-30 MPa to power anchor removal or reinforcement tasks. In high-altitude or restricted sites where standard electric or pneumatic motors face limitations, the unit utilizes the available hydraulic infrastructure.

For high-altitude, low-temperature, or highly corrosive environments, the factory supplies specific seal and material options. Input pressure matching, output flow, and interface specifications are customizable, with a 1 to 3-month sample lead time. The drive system and working fluid system run in independent circuits to prevent contamination and extend service life in dusty conditions. Every unit undergoes 100% inspection before packing in solid wood crates.
