Large-tonnage servo hydraulic press for stack assembly is specifically designed for high-volume production of large-format, high-power stacks, enabling high-precision assembly and online gas leak testing for PEM electrolyzers, fuel cell stacks, and flow battery stacks.
The equipment features a heavy-duty frame structure and a high-efficiency servo hydraulic system, delivering micron-level control precision while meeting assembly requirements of over a hundred tons. It serves as core manufacturing equipment for the mass production of green hydrogen equipment and energy storage batteries.
PRODUCT DESCRIPTION
Core Technological Advantages
1. Ultra-Precision Dual Closed-Loop Control of Pressure and Position
High-response servo motor, imported pressure sensor, and grating scale enable full closed-loop control.
Pressure repeatability accuracy ≤ [±0.5%] F.S., Position control accuracy ≤ [±0.01mm].
Constant pressure holding ensures uniform contact between bipolar plates and membrane electrode assembly (MEA), preventing damage.
2. Advanced "Fast-Slow Combined" Assembly Process
Multi-stage adjustable speed: Rapid descent, slow approach (minimum [0.1mm/s]), and rapid return, eliminating impact and preventing plate misalignment.
Unique pressure relief circuit avoids stack loosening caused by unloading shock.
3. High Tonnage, High Rigidity & Eccentric Load Resistance
Integrated welded frame, stress-relieved through annealing, offering high strength and minimal deformation.
Precision guiding (linear guides/four-corner eight-face guides) ensures parallelism between slide and worktable ≤ [0.02/300mm] under high tonnage ([200 tons] - [600 tons]), effectively withstanding eccentric loads.
4. Intelligent Data Acquisition & Traceability
Industrial touch screen plus dedicated control system displays real-time pressure-displacement curves.
Data storage and export capabilities enable full lifecycle traceability with "one stack, one file," complying with IATF 16949 standards.
5. Flexible Production & Comprehensive Safety
Worktable equipped with T-slots/locating pins for quick mold changes, adaptable to multi-variety production.
Multi-level safety protection: Light curtains, safety door interlocks, overload protection, and audible/visual alarms.
Application Scenarios
This equipment is widely used in precision assembly lines within the new energy sector:
●Hydrogen Fuel Cell Stack Assembly: Stacking and compression for graphite plate stacks and metal bipolar plate stacks.
●PEM Electrolyzer Manufacturing: End plate compression and pre-assembly before leak testing for hydrogen production equipment.
●Large-format Flow Battery Stack Assembly: Stack compression for energy storage batteries such as Vanadium Flow Batteries (VFBs).
