Product Description Product DescriptionI. Basic Functions- Precise Pressure Control: The tensioning pressure value (corresponding to the tensioning force) is set electronically, and the hydraulic system automatically adjusts the output pressure to ensure that the error between the actual pressure and the set value is kept to a very small range (typically ≤±1%).- Automated Tensioning Process: Preset tensioning procedures (such as "initial stress → holding load → staged tensioning → anchoring") are available, automatically completing the steps of pressure increase, holding load, and pressure replenishment, reducing manual intervention.- Data Recording and Storage: Real-time data such as pressure, displacement, and time are collected during the tensioning process, automatically generating tensioning records that can be stored locally or transmitted remotely for easy traceability and archiving.II. Core Components- Hydraulic System: This includes the oil pump, oil tank, and hydraulic valve block. It provides stable hydraulic power and precisely regulates pressure through proportional valves. - Control System: Comprised of a PLC (Programmable Logic Controller), a touch screen, and sensors (pressure and displacement sensors), it serves as the equipment's "brain," responsible for command issuance, data collection, and logical analysis.- Operation and Display Unit: Parameter settings (such as tensioning tonnage and hold time) are performed via the touch screen or keypad. Real-time display of tensioning progress, pressure, displacement, and other information provides intuitive feedback on construction status.- Safety Protection Devices: Equipped with overload protection (automatic shutdown due to overpressure), an emergency stop button, and an over-oil temperature alarm, they ensure the safety of equipment and personnel.III. Main Technical Features- Synchronous Tensioning Capability: Supports coordinated control of multiple units, enabling simultaneous tensioning of multiple strands (e.g., simultaneous construction of bridge web and roof slab strands), ensuring uniform stress distribution.- Remote Control and Networking: Some units feature wireless communication, enabling remote monitoring of the tensioning process via mobile app or computer, and even enabling coordinated management of multiple units, making them suitable for centralized control of large-scale projects. - Strong adaptability: It can adapt to jacks of different specifications (such as 200 tons, 500 tons, 1000 tons, etc.), and meet the tensioning process requirements of different prestressed steel strands (steel strands, precision-rolled rebar) through parameter adjustment..Major parameter and main configuration1.

Primary pump storage U disk (4G) Working Principle When using prestressed intelligent tension system, the main pump and the auxiliary pump are wirelessly connected, and the auxiliary pump will shift and pressure The signal is transmitted to the main pump. After the main pump processes the signal, it transmits the control signal to the auxiliary pump to control the oil supply, and stops and returns the jack. During the tensioning construction, the on-site tensioning parameters of the main pump are wirelessly transmitted to the on-site monitoring computer for storage to prevent the tensioning parameters from being lost due to transmission problems. Our AdvantagesIntelligent tensioning pumps and jacks are key equipment in modern prestressed construction. They offer numerous advantages over traditional equipment, primarily in the following areas:1. High tensioning precision and better quality control- Computer program control enables precise setting of parameters such as tensioning stress and elongation, with errors typically within a narrow range (typically within ±1%). This avoids under- or over-tensioning problems often caused by traditional manual operation due to factors like experience and physical strength.- Automatically records data during the tensioning process (such as stress, elongation, and time), providing traceability and facilitating quality verification and troubleshooting.2. High degree of automation, saving labor costs- Automatically performs processes such as pressure increase, load holding, pressure replenishment, and anchoring, reducing manual intervention and reliance on operator skills.- A single set of equipment reduces the number of operators and improves construction efficiency.3. Improved safety- Features such as overload protection and emergency shutdown mitigate safety risks caused by equipment failure or operator error. - Remote control (for some equipment) reduces personnel exposure time in high-risk areas.4. Improved Construction Efficiency- The tensioning process is automated according to pre-set procedures, eliminating the waiting and adjustment time associated with manual operation and shortening the single-tie tensioning cycle.- Automatic data storage and transmission reduces the workload of manual recording and organization during later stages.5. Adaptability to Complex Working Conditions- Program adjustments can be made to accommodate different steel strand specifications and different tensioning processes, providing high flexibility.- In large-scale projects such as bridges and tunnels, it can better coordinate the simultaneous tensioning of multiple strands, ensuring uniform stress distribution in the structure.These advantages have led to the widespread use of intelligent tensioning equipment in prestressed steel projects such as bridges and high-rise buildings, effectively ensuring project quality and construction safety.For more information, please contact Emily~~ application As core equipment for prestressing construction, intelligent tensioning pumps, with their high precision and automation advantages, are widely used in various engineering fields requiring prestressing technology, primarily in the following scenarios:1. Bridge Engineering- Beam Construction: During the prestressing of precast box beams, T-beams, and continuous beams, these pumps are used to tension steel strands or high-strength steel wires, ensuring uniform stress distribution and improving load-bearing capacity.- Bridge Reinforcement: During the repair or reinforcement of prestressed structures on existing bridges, these pumps precisely control tensioning parameters to ensure effective reinforcement.- Cable-Stayed and Suspension Bridges: During the tensioning of cables and suspenders, these pumps achieve simultaneous tensioning of multiple strands to ensure structural stability.2. Construction Engineering- Long-Span Structures: Precisely control tensioning forces during the prestressing of long-span floor slabs and roofs, such as those in stadiums and exhibition centers, to minimize structural deformation.- High-Rise Buildings: During the prestressing of transfer beams and shear walls, these pumps improve structural crack resistance and stiffness. - Underground Engineering: For example, jacking construction or prestressed reinforcement of structures in subway stations and utility corridors to adapt to complex underground load environments.3. Transportation Engineering- Highway and Railway Slope Reinforcement: Prestressed anchor cables and bolts are used to stabilize slopes and prevent landslides and other geological hazards.- Tunnel Engineering: Prestressed technology is used in tunnel lining and surrounding rock reinforcement to enhance structural integrity and resist surrounding rock pressure.4. Water Conservancy Engineering- Dams, sluices, and other hydraulic structures: During the construction of prestressed piers, corridors, and other structures, tensioning control is used to ensure structural impermeability and load-bearing capacity to withstand water pressure.5.
