This large-scale electrostack assembly servo press is the core equipment designed for the large-scale and high-quality production of liquid-flow battery electrostacks.
Through the high-precision servo control system, it applies extremely precise pressure and displacement control to the assembly process of the stack to ensure that each piece of electrode, bipolar plate, runner frame and sealing layer is tightly combined under uniform and reliable mechanical conditions. This not only directly affects the power output, cycle efficiency and service life of the stack, but is also the key guarantee to achieve product consistency and high yield, and to promote the flow battery technology from demonstration application to large-scale industrial deployment.
PRODUCT DESCRIPTION
Main Functions of the Large-Scale Servo Press for Stack Assembly
●Positioning and Pre-pressing: Precisely aligns the stacked components.
●Dwell Curing and Pressurization: Applies uniform, immense pressure (typically tens to hundreds of tons) to deform the seals (such as gaskets), ensuring the sealing of internal cavities within the stack and preventing electrolyte leakage.
●Locking Assembly: While maintaining pressure, long tie rods running through the stack are tightened manually or automatically to lock the stack's height and preload force.
Technical Advantages
1. High-Precision Synchronous Control:
Due to the large area of flow battery stacks, multi-cylinder synchronous control technology is often used to ensure uniform pressure. Equipment like that from ShunTian may be equipped with high-response servo valves and controllers, ensuring no eccentric load during the pressing process, with balance accuracy reaching within 0.1mm.
2. Closed-Loop Pressure and Displacement Control:
The stack's compression height directly impacts battery performance. This equipment can precisely control the final height after pressing and display the pressure-displacement curve in real-time for quality traceability.
3. Large Platen and Extra-Wide Opening:
To accommodate industrial-grade flow battery stacks (e.g., tens of kilowatts or even megawatt-level modules), the press platen size is typically very large (e.g., 1.5m x 2m or larger), and the opening height must be sufficient to accommodate the stacked components.
4. Servo Energy-Saving Technology:
Compared to traditional hydraulic presses, servo-drive technology significantly reduces energy consumption. This is particularly important for long-dwell processes, which can last several minutes or even tens of minutes.
