PRODUCT DETAILS

A prestressing tensioning oil pump is the core power source for prestressing construction. Its primary functions are:

- To supply high-pressure, stable, and controllable hydraulic oil to prestressing jacks (typically at pressures of 50–80 MPa)

- To drive the jacks to tension steel strands or reinforcing bars, thereby applying prestressing using the pre-tensioning or post-tensioning method

- Precisely control tensioning force, load holding, oil return, and pressure maintenance to meet design stress and elongation requirements

- Can be integrated with heading machines, extrusion machines, grouting equipment, and other devices to perform auxiliary processes such as anchoring, extrusion, and pressure testing

Typical Application Scenarios

1. Bridge Engineering (Most Common)

- Longitudinal/transverse prestressing of precast T-beams, box girders, and hollow slabs

- Tensioning of main cables/anchor cables for continuous beams, rigid-frame bridges, suspension bridges, and cable-stayed bridges

- Prestressing construction for municipal elevated bridges, ramps, and interchanges

2. Building Construction

- Post-tensioning construction for shear walls, frame beams, and long-span floor slabs in high-rise buildings

- Long-span prestressed structures in large stadiums, convention centers, and airport terminals

- Prestressing reinforcement in the strengthening, underpinning, and jacking of existing buildings

3. Water Resources and Hydropower

- Tensioning of anchor cables/bolts for dams, gate piers, and spillways

- Prestressed concrete construction for hydropower plant buildings, pressure pipelines, and surge chambers

4. Transportation and Geotechnical Engineering

- Anchor systems for highway/railway slopes, deep excavation shoring, and underground diaphragm walls

- Prestressing reinforcement for tunnel linings, segmental linings, and shield launch/reception portals

- Tensioning construction for subway, light rail, and high-speed rail track beams and platform beams

5. Precast Component Plants

- Mass production of pre-tensioned prestressed pipe piles, utility poles, sleepers, and box girders

Key Components and Operating Conditions

- Common Models: ZB Series (e.g., ZB2×2/50, ZB4-600), dual-line, high-pressure, synchronous control

- Compatibility: YCW through-type jacks (100–5000 kN), suitable for single-strand and multi-strand synchronous tensioning

- Operating Conditions: Complex environments such as high-altitude, confined spaces, underwater, open-air, and high/low-temperature conditions

Prototype with dual circuits

Solenoid-operated single-circuit oil pump = a hydraulic power unit featuring a single oil circuit (with only one high-pressure outlet and return line) and an integrated solenoid directional control/unloading valve, specifically designed for precise, electronically controlled, and pressure-maintaining operation of a single actuator (single jack or single cylinder).

Integrated Mortar Pump

The integrated design of the mixing and storage tank and pumping mechanism eliminates the need for a separate mixer. The feeding, mixing and conveying are completed in one go. It can transport cement mortar, cement slurry and grouting material, and is mostly used in small-scale grouting, repair, plastering and prestressed assisted grouting construction site scenarios.

Twin-Cylinder Slurry Pump

The dual-cylinder grouting pump uses two oil cylinders to alternately suck and discharge grout, resulting in continuous discharge without pulses, high pressure, and stable flow. Compared with the single-cylinder pump, it has higher efficiency and better pressure stabilization effect, making it the main equipment for large-scale grouting projects in roads, bridges, tunnels, mines, and foundation pits.
